The present invention is directed to improved methods for the treatment of anxiety. Anxiety occurs in a patient suffering from an anxiety disorder, but is also a symptom of other mental or nervous system disorders.
The treatment comprises administering to a patient in need thereof a therapeutically effective amount of 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) or of a pharmaceutically acceptable salt thereof.
Anxiety is a feeling of uneasiness and worry. Experiencing occasional anxiety is a normal part of life.
However, individuals with anxiety disorders frequently have intense, excessive and persistent worry and fear about everyday situations.
Often, anxiety disorders involve repeated episodes of sudden feelings of intense anxiety and fear or terror that reach a peak within minutes (panic attacks).
These feelings of anxiety and panic interfere with daily activities, are difficult to control, are out of proportion to the actual danger and can last a long time. Avoidance behaviour can be a result to prevent these feelings.
Anxiety can be either idiopathic or can occur in the context of a medical condition such as mental disorders or nervous system disorders. In fact, several mental disorders and nervous system disorders are known to be associated with anxiety. Anxiety also occurs in patients suffering from certain medical health conditions leading to associated mental or nervous system conditions.
Anxiety can not only have a severe impact on the quality of life but can also lead to, or worsen, other mental and physical conditions, such as depression, which can be associated with an anxiety disorder, or other mental health disorders, cognitive dysfunction, sleep disturbance (for instance, insomnia), substance misuse, digestive or bowel problems, headaches and chronic pain, social isolation, problems functioning at daily life, and suicide.
Current treatment options for conditions involving anxiety are limited.
Thus, there is a need for an improved treatment of such conditions, in particular for anxiety associated with a mental disorder or a nervous system disorder and in patients suffering from certain medical health conditions leading to associated mental or nervous system conditions.
An aim of the invention is in particular the provision of therapies which are more effective (i.e., a) a larger percentage of patients experiencing a clinical response, b) a larger average clinical response, c) an earlier onset of the clinical response, and/or d) a more durable clinical response) than previously described therapies.
A further aim of the current invention is to provide a compound for improved psychoactive therapies and dosing regimens for said therapies which have a better safety profile and/or are better tolerated than previously described therapies. Another aim of the current invention is to provide a compound for improved psychoactive therapies and dosing regimens for said therapies which are more convenient than previously described therapies. Another aim of the current invention is to provide a compound for improved psychoactive therapies and dosing regimens for said therapies which are associated with higher rates of patient compliance (including higher rates of treatment initiation) than previously described therapies. A still further aim of the current invention is to identify specific disease aspects and specific subgroups of disease aspects which benefit from such improved psychoactive therapies.
The present invention provides 5-Methoxy-N,N-dimethyltryptamine (5-MeO-DMT) or a pharmaceutically acceptable salt thereof for use in treating a patient suffering from anxiety. The patient may be suffering from an anxiety disorder, from a mental or nervous system disorder and subthreshold anxiety or may have a comorbidity of anxiety and a further diagnosed disorder.
The anxiety may occur in a patient suffering a mental or nervous system disorder, such as disorders characterized by depressive episodes for example, Major Depressive Disorder (MDD), Postpartum Depression (PPD), Persistent Depressive Disorder, Seasonal Affective Disorder and Bipolar Disorder (BD), such as Bipolar I Dis-order and Bipolar II Disorder; Anxiety Disorder, for example Separation Anxiety Disorder, Agoraphobia, Generalised Anxiety Disorder (GAD), Social Anxiety Disorder (SAD), Panic Disorder, Phobias, and Substance/Medication Induced Anxiety Disorder; Somatic Symptom Disorder; Obsessive Compulsive and Related Disorders, for example, Obsessive Compulsive Disorder (OCD) and Body Dysmorphic Disorder (BDD); Post-Traumatic Stress Disorder (PTSD); Pain Disorders, for example Chronic Pain, Fibromyalgia and Migraine; Mental and Behavioural Disorders due to Psychoactive Substance Use, for example, Substance Use Disorder (SUD); Psychotic Disorders, for example Schizophrenia; Parkinson's Disease; Dementia, for example Alzheimer's Dementia (AD), Parkinson's Disease Dementia (PDD), Dementia with Lewy Bodies, Vascular Dementia, Fronto-Temporal Dementias; Eating Disorders; Attention Deficit Hyperactivity Disorder (ADHD); Personality Disorders, for example Schizotypal Personality Disorder and Borderline Personality Disorder; Autism Spectrum Disorder; Chronic Fatigue Syndrome; or a medical health conditions leading to an associated mental or nervous system condition, for example Anxiety due to Traumatic Brain Injury (TBI), HIV infection or Post COVID Condition.
The patient may also suffer from sleep disturbance associated with anxiety.
The present invention also provides dose ranges and dosing regimen useful for the treatment of anxiety.
In the context of the present invention, 5-MeO-DMT or a pharmaceutically acceptable salt thereof is administered via intravenous, intramuscular or subcutaneous administration.
5-MeO-DMT or a pharmaceutically acceptable salt thereof is administered at a dose or in a dosage regimen that causes the patient to experience a peak psychedelic experience. A dosage of about 1 mg to about 10 mg 5-MeO-DMT or an equimolar amount of a pharmaceutically acceptable salt may be administered.
As used in the context of the present invention, unless otherwise noted, the term “5-MeO-DMT” refers to the free base 5-MeO-DMT. It is contemplated that pharmaceutically acceptable salts of 5-MeO-DMT may also be used. Such salts are in particular acid addition salts, wherein the acid may be selected from, for instance, acetic acid, benzoic acid, citric acid, fumaric acid, hydrobromic acid, hydrochloric acid, hydrofluoric acid, hydroiodic acid, oxalic acid, succinic acid and triflic acid. A preferred example is the hydrobromide salt. The appropriate weight amount of a salt to be administered can be calculated from the weight amount of the free base, assuming that equimolar amounts are used.
As used in the context of the present invention, a “patient” to be treated is a human subject who is diagnosed with anxiety by a licensed professional in accordance with accepted medical practice or who is diagnosed by a licensed professional in accordance with accepted medical practice with a mental disorder or a nervous system disorder associated with anxiety. In the latter case, assessing anxiety may or may not be part of the diagnosis.
Diagnosis of a mental disorder or a nervous system disorder can, for instance, be in accordance with the Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (DSM-5) published by the American Psychiatric Association. The diagnosis will be by a physician or a psychologist. It is not sufficient that the human subject himself/herself considers that he/she is suffering from the disorder.
As used in the context of the present invention, unless otherwise noted, the terms “treating” and “treatment” shall include the management and care of a patient for the purpose of combating a disease, condition, or disorder and includes the administration of compounds and methods according to the present invention to alleviate the signs and/or symptoms of the disease or eliminate the disease, condition, or disorder.
“Treatment of anxiety” shall include the management and care of a patient for the purpose of combating anxiety and includes the administration of compounds and methods according to the present invention to alleviate the signs and/or symptoms of anxiety or eliminate anxiety.
The patient may suffer from an anxiety disorder or a disorder associated with anxiety. Anxiety may be associated with sleep disturbance.
The patient may suffer from treatment resistant disease. Treatment resistance means that the patient had no adequate improvement after at least two adequate courses of therapy. The patient in particular had no adequate improvement after at least two adequate courses of therapy, wherein at least one of the two courses was a pharmacotherapy; for instance, the patient had no adequate improvement after at least two adequate courses of pharmacotherapy. The at least two prior courses of treatment were in particular administered in the current episode of the disease, for instance, if the patient suffers from a disorder characterized by depressive episodes, in the current episode of depression.
As used in the context of the present invention, “suicidal ideation” refers to thinking about, considering, or planning for suicide. The presence of suicidal ideation in a patient will be diagnosed by a physician or a psychologist, using established protocols and methods for diagnosing suicidality. It is generally not sufficient that the patient himself considers that he is suffering from suicidal ideation. In some situations, a patient experiencing suicidal ideation will be at imminent risk of committing suicide, or will be considered to have ‘intent to act.’
As used in the context of the present invention, unless otherwise noted, the term “therapeutically effective amount” shall mean the amount of active compound or pharmaceutical ingredient that elicits the biological or clinical response in a human that is being sought by a researcher, medical doctor or other clinician, which includes alleviation of the signs and/or symptoms of the disease, condition or disorder being treated.
“Clinical response” includes, but is not limited to, improvements on rating scales. These scales assess (i) anxiety or aspects of anxiety and/or (ii) a mental disorder or nervous system disorder or aspects of such a disorder.
The severity of a condition as well as changes of the severity can be assessed by the Clinical Global Impression (CGI) rating scales which are measures of symptom severity, treatment response and the efficacy of treatments.
The CGI rating scales were developed to provide a brief, stand-alone assessment of the clinician's view of the patient's global functioning prior to and after a treatment (Busner, J. and Tagrum, S. D., 2007. The Clinical Global Impressions Scale: Applying a Research Tool in Clinical Practice. Psychiatry 2007, 29-37).
The CGI-Severity (CGI-S) is based on one question the clinician has to answer: “Considering your total clinical experience with this particular population, how mentally ill is the patient at this time?” This is rated on the following seven-point scale: 1=normal, not at all ill; 2-borderline mentally ill; 3=mildly ill; 4=moderately ill; 5=markedly ill; 6=severely ill; 7=among the most extremely ill patients.
The CGI-S can be used to assess treatment success by comparing scores before and after treatment.
Alternatively, treatment success can be assessed using the CGI-Improvement (CGI-I), which is similarly simple in its format. After the treatment, the clinician compares the patient's overall clinical condition to the one prior to the treatment (the so-called baseline value). Again, only one query is rated on a seven-point scale: “Compared to the patient's condition at admission to the project [prior to medication initiation], this patient's condition is: 1=very much improved since the initiation of treatment; 2=much improved; 3=minimally improved; 4=no change from baseline (the initiation of treatment); 5=minimally worse; 6=much worse; 7=very much worse since the initiation of treatment.”
The Patient Global Impression scale (PGI), also known as Subject Global Impression (SGI), is the counterpart to the Clinical Global Impressions scale (CGI). It consists of one item based on the CGI and adapted to the patient. It can measure disease severity (PGIS) or disease improvement (PGI-I).
Individual items of scales as described herein as well as sub-combinations of individual items may be used to assess specific disease aspects.
As used in the context of the present invention, unless otherwise noted, the term “administration” (or “application”) shall mean the introduction of an amount, which may be a predetermined amount, of active compound or pharmaceutical ingredient into a patient via any route. The active compound is administered by intravenous administration, by intramuscular administration or by subcutaneous administration.
As used in the context of the present invention, unless otherwise noted, the terms “dose” and “dosage” and “dosage amount” shall mean the amount of active compound or pharmaceutical ingredient which is administered to a patient in an individual administration. The term “dosage regimen” (or “dosing regimen”) shall mean a defined sequence of one or more individual administrations.
Anxiety is sometimes defined as an “apprehensive anticipation of future danger or misfortune accompanied by a feeling of dysphoria or somatic symptoms of tension”.
Anxiety is characterized by an intense, excessive, and persistent worry and fear about a situation that is only subjectively seen as menacing and is often accompanied by muscular tension, restlessness, fatigue, inability to catch one's breath, tightness in the abdominal region, nausea, and problems in concentration.
In anxiety disorders or other mental or nervous system disorders associated with anxiety, the feelings of anxiety are difficult to control and interfere with daily activities.
Anxiety is a core feature of anxiety disorders, including separation anxiety disorder, specific phobia, social anxiety disorder (social phobia), panic disorder, generalized anxiety disorder (GAD), agoraphobia, and substance/medication-induced anxiety disorder.
Anxiety is moreover associated with several other mental and nervous system disorders. Anxiety is also associated with sleep disturbance.
Several rating scales to assess anxiety are known on the art, and anxiety symptoms are furthermore assessed as part of various rating scales used to assess mental and nervous system disorders.
The Hamilton Anxiety Rating Scale (HAM-A) is designed to assess anxiety symptoms. The scale is clinician-administered. It has 14 items which can be divided into a group of psychic items (1-6 and 14) measuring in particular mental agitation and psychological distress and into a group of somatic items (items 7-13) measuring in particular physical complaints related to anxiety.
The HAM-A items are shown in the table below.
Each item is rated by the interviewer on a scale from 0 to 4:0=Not present, 1=Mild, 2=Moderate, 3=Severe, 4=Very severe.
A total score is obtained by summing the 14 items. The total score range is 0-56. Higher scores indicate more anxiety.
A score·7 is considered to represent no or minimal anxiety; a score of 8-14 mild anxiety; a score of 15-23 moderate anxiety; a score·24 severe anxiety.
The Beck Anxiety Inventory (BAI) is a 21-item self-report questionnaire developed to assess anxiety, with a focus on somatic symptoms. The items are rated on a four-point Likert scale ranging from zero (not at all) to three (severely: I could barely stand it). The total score ranges from 0 to 63.
Subthreshold anxiety as the term is used herein in particular means that the patient has a Hamilton Rating Scale for Anxiety (HAM-A) score of at least 9 but of less than 18 and/or a Beck Anxiety Inventory (BAI) score of at least 11 but of less than 16.
Numerous scales have been suggested to assess severity of a mental disorder or a nervous system disorder. Such scales are based on tests which can be self-administered or administered by a clinician.
Scales which may be used according to the invention include those known in the art for diagnosis and/or monitoring the mental or nervous system disorders discussed in more detail below.
Treatment outcome is assessed by using one or more indices or scales at one or more time points after completion of a treatment course.
The assessment can be carried out after the acute psychedelic experience has subsided. An appropriate point in time for an early assessment is generally about 2 to 3 hours after the last administration. An early assessment can generally be carried out, for instance, about 2 hours or about 3 hours after the last administration.
An assessment of an effect on sleep disturbance can, however, be carried out at the earliest on the day after the treatment (i.e., on day 1) so that the treated patient had the opportunity to sleep for at least one night.
Thus, an assessment at day 1 or on day 1 means an assessment on the day following the administration. The assessment will be carried out not earlier than 12 hours after the last administration and in any event not earlier than one night after the last administration and not later than 36 hours after the last administration. The assessment can be carried out after about 24 hours.
An assessment at day 7 or on day 7 means an assessment on the seventh day following the administration (the day of administration is day 0). Analogous definitions apply for other assessment timings measured in days.
When assessing a clinical response, for instance, using one of the scales to assess severity of a mental disorder or a nervous system disorder, at an early timepoint after drug administration (e.g. at 2 hours) based on endpoints which have been developed for a longer recall period (e.g. normally 7 days for the MADRS), a rational modification of such endpoint (e.g. changing the MADRS recall period to 2 hours and carrying forward the sleep item recorded at baseline before drug administration) may be applied. The same applies with respect to any other scale applied herein, unless a recall period is specifically indicated.
The considerations outlined apply for early timepoints because, on the one hand, in order to assess a clinical response, the influence of the patient's status before the treatment on any score recorded after treatment should be kept as low as possible, whereas on the other hand the sleep item cannot be assessed 2 hours after drug administration.
At later timepoints, for instance, on day 1 or later, typically all items of the relevant scales to assess a clinical response can be assessed, using, if necessary, an adapted recall period, so that it is not necessary to carry forward any pre-treatment score.
The Brief Psychiatric Rating Scale (BPRS) is intended to screen for psychiatric symptoms in a structured fashion. The scale is one of the most widely used scales to measure psychotic symptoms and was first published in 1962. The design has later been updated. The version most often used today includes 18 different areas for physicians or psychologists to evaluate (Overall, J. E. and Gorham, D. R., 1962. The brief psychiatric rating scale. Psychological Reports 10, p. 799; Overall, J. E. and Gorham, D. R., 1988. The Brief Psychiatric Rating Scale (BPRS): recent developments in ascertainment and scaling. Psychopharmacology Bulletin 22, p. 97).
The 18 items (somatic concern, anxiety, emotional withdrawal, conceptual disorganization, guilt feelings, tension, mannerisms and posturing, grandiosity, depressive mood, hostility, suspiciousness, hallucinatory behaviour, motor retardation, uncooperativeness, unusual thought content, blunted affect, excitement and disorientation) are scored and each item is rated on a scale of 1-7.
A physician or psychologist will complete two tasks during an approximate 15-minute interview with the patient:
Based on the answers and the behaviours observed, a physician or psychologist will complete the BPRS form by ranking the severity of each area using a scale of one to seven: a score of one means an absence of signs or symptoms up to a score of seven that means it is present and at a severe level. If it is not possible to rate the specific signs or symptoms, a score of 0 or “Not assessed” is recorded.
The Columbia Suicide Severity Rating Scale (C-SSRS) is a detailed questionnaire assessing both suicidal behaviour and suicidal ideation to help identify if there is an immediate need for medical intervention as well as providing data for the overall assessment of a treatment effect in relation to suicidality. The C-SSRS is evidence-supported and is part of a national and international public health initiative involving the assessment of suicidality (Posner, K., Brown, G. K., Stanley, B., Brent, D. A., Yershova, K. V., Oquendo, M. A., Currier, G. W., Melvin, G. A., Greenhill, L., Shen, S., and Mann, J. J., 2011. The Columbia-Suicide Severity Rating Scale: Initial Validity and Internal Consistency Findings From Three Multisite Studies With Adolescents and Adults. American Journal of Psychiatry 168 (12), p. 1266-77).
Brain processes can be studied by functional magnetic resonance imaging (fMRI). Brain activity is associated with blood flow, and temporal correlations of spontaneous blood oxygen level dependent (BOLD) signal fluctuations between different brain areas can be measured.
Functional images of the brain are acquired over the course of several minutes. Patterns of low-frequency BOLD signal oscillation are observed across the brain. The decomposition of this spontaneous signal reveals distributed areas with correlated and anti-correlated fluctuations.
In this way, resting-state fMRI can be used to characterize large-scale functional networks, so-called resting-state networks (RSN), which are a set of spatially distinct brain regions that show coordinated activity in the absence of any explicit cognitive task (i.e., at rest). The observed patterns, characterizing a network of brain regions with coherent patterns of signal variation, are called resting-state networks (RSN).
Different resting state networks have been identified and named mostly based on spatial similarity between the resting state networks and activation patterns seen in task fMRI experiments.
Resting-state fMRI can therefore be used to assess the intrinsic functional organization of the brain. Resting-state networks have been characterized for aspects of attention, memory, cognitive control, default mode, motor, and sensory system.
RSNs have been shown to be responsible for various aspects of complex brain function, and it has been found that these connectivity networks are compromised in various disease states. Such disease states, which include certain forms of anxiety, are associated with altered functional connectivity within a specific resting state network and/or between one or more regions in one or more additional resting state networks.
Based on such studies, a number of brain regions have been implicated in anxiety and anxiety disorders. Accordingly, anxiety and anxiety disorder pathophysiology involves aberrant connectivity between amygdala-frontal and frontal-striatal regions. Anxiety and anxiety disorders are associated with specific alterations to resting state networks.
Anxiety and anxiety disorders show abnormalities within and/or between default mode network, salience network and sensorimotor network. The resting state balance within and/or between each of these networks differs in the different anxiety disorders.
The above discussion shows that anxiety as such presents a significant disease burden and deserves appropriate treatment.
The inventors considered that a carefully chosen hallucinogen may lead to an improved treatment of important aspects of anxiety and may lead to overall improvements of the condition.
One group of hallucinogens entails compounds which bind to the 5-hydroxytryptamine (5-HT) receptors, which are also referred to as serotonin receptors (described are 7 families 5-HT1 to 5-HT7 with several subtypes). Examples are lysergic acid diethylamide (LSD), psilocybin, and N,N-dimethyltryptamine (DMT). These serotonergic agents are often referred to as “psychedelics”, which emphasizes their predominant ability to induce qualitatively altered states of consciousness such as euphoria, trance, transcendence of time and space, spiritual experiences, dissolution of self-boundaries, or even near-death experiences, while other effects such as sedation, narcosis, or excessive stimulation are only minimal.
Chemically, serotonergic psychedelics are either phenylalkylamines or indoleamines, with the indoleamine class being divided into two subsets, ergolines and tryptamines, the latter being derived from tryptamine.
The various serotonergic psychedelics have different binding affinity and activation potency for various serotonin receptors, particularly 5-HT1A, 5-HT2A, and 5-HT2C, and their activity may also be modulated by interaction with other targets such as monoamine transporters and trace amine-associated receptors.
Recently published clinical studies which have used serotonergic psychedelic drugs such as LSD, psilocybin and DMT (using the shamanic brew Ayahuasca, which contains DMT) in certain mental disorders suggest that those compounds could provide an alternative to the currently available treatments for certain mental disorders. However, there are reports that these compounds can induce mania in patients suffering from depressive symptoms, and this may preclude their clinical use.
For instance, Lake et al. (Lake, C. R., Stirba, A. L., Kinneman, R. E. Jr, Carlson, B., Holloway, H. C., 1981. Mania associated with LSD ingestion. American Journal of Psychiatry. 138 (11): 1508-9) report about a patient who suffered a manic attack after ingesting LSD or an LSD analogue. The patient experienced acute symptoms of LSD intoxication, which resolved but were followed in about 3 weeks by a typical manic episode of psychotic magnitude. Hendin and Penn (Hendin, H. M., Penn, A. D., 2021. An episode of mania following self-reported ingestion of psilocybin mushrooms in a woman previously not diagnosed with bipolar disorder: A case report. Bipolar Disorders 23 (4): 1-3) report about an episode of mania following self-reported ingestion of psilocybin mushrooms. Szmulewicz et al. (Szmulewicz, A. G., Valerio, M. P., and Jose M Smith, J. M., 2015. Switch to mania after ayahuasca consumption in a man with bipolar disorder: a case report. International Journal of Bipolar Disorders (2015) 3:4) report on a switch to mania after consumption of ayahuasca, a DMT containing brew, in a man with bipolar disorder.
A further case report is found in Brown, T., Shao, W., Ayub, S., Chong, D., & Cornelius, C. (2017). A Physician's attempt to self-medicate bipolar depression with N, N-dimethyltryptamine (DMT). Journal of Psychoactive Drugs, 49 (4), 294-296.
The inventors considered that in order to avoid the induction of mania or hypomania or at least reduce the risk of induction of mania or hypomania, the compound administered must be appropriately chosen and preferably is administered in a particular dosing regimen.
The inventors identified 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) as a psychedelic of particular interest for use in therapy. 5-MeO-DMT has a distinct pharmacological profile which differs from that of other psychedelic compounds.
5-MeO-DMT is a potent, fast-acting, naturally occurring serotonin (5-HT) agonist, acting at both the 5-HT1A and the 5-HT2A receptor, with higher affinity for the 5-HT1A receptor subtype compared to other classical psychedelics.
Inhibition constants (Ki values) as further detailed on the example section below for psilocin (the dephosphorylated from of psilocybin which is formed after uptake of psilocybin), DMT and 5-MeO-DMT are 48, 38 and 1.80 nM, respectively, at 5-HT1A receptors located in the hippocampus of post-mortem human brain. Thus, 5-MeO-DMT exhibits high affinity and psilocin and DMT exhibit moderate affinity for 5-HT1A receptors. Inhibition constants (Ki values) for psilocin, DMT and 5-MeO-DMT are 37, 117 and 122 nM, respectively, at 5-HT2A receptors located in the frontal cortex of post-mortem human brain. Therefore, psilocin exhibits moderate/strong affinity and DMT and 5-MeO-DMT exhibit comparatively weak affinity for 5-HT2A receptors.
Relative to the other psychoactive compounds mentioned previously, 5-MeO-DMT displays an enhanced affinity for the 5-HT1A receptor, where it acts as a potent agonist. In the case of psilocin and DMT, there is an increased contribution of 5-HT2A binding, relative to 5-MeO-DMT, with the latter displaying the largest differential affinity for 5-HT1A over 5-HT2A of the three compounds. Therefore, 5-HT1A binding plays a much bigger role in the overall effect of 5-MeO-DMT relative to 5-HT2A binding compared to the other two compounds.
It has been reported that 5-HT1A agonism reduces impulsivity and aggression, whereas 5-HT2A agonism can result in short-term increases in these same traits. Moreover, 5-HT1A agonists have anxiolytic effects. Furthermore, the dopamine system has been implicated in contributing to mania, with increased dopamine drive being linked to mania. LSD, psilocybin and DMT all display increased affinity for a variety of dopamine receptors relative to 5-MeO-DMT
Compared to other psychedelics, like LSD, psylocibin or DMT, 5-MeO-DMT can be administered to patients, preferably using dosing schemes as described herein, without a significant risk of inducing mania or hypomania in a patient suffering from a mental or nervous system disorder, including a disorder characterized by depressive episodes, for example, Major Depressive Disorder (MDD), Postpartum Depression (PPD), Persistent Depressive Disorder, Seasonal Affective Disorder and Bipolar Disorder (BD), such as Bipolar I Disorder and Bipolar II Disorder; a Psychotic Disorder, such as Schizophrenia; or a personality disorder, such as Schizotypal Personality Disorder. The patient suffering from such a mental or nervous system disorder, treated according to the invention, does not experience treatment-emergent mania or hypomania.
It is also noted that reports of treatment-emergent mania or hypomania related to psychoactive substance use seem to indicate large quantities of the respective compounds (e.g., DMT/ayahuasca, psilocybin, LSD) were used.
The inventors' approach of sequential up-titration of 5-MeO-DMT significantly reduces the risk of excessive dose administration with its potential for attendant adverse events.
Still further, the induction by antidepressants of isolated events of hypomania has been reported in patients suffering from treatment resistant depression (TRD) (Bader, Cynthia D., and David L. Dunner. “Antidepressant-induced hypomania in treatment-resistant depression.” ⋅Journal of Psychiatric Practice⋅13.4 (2007): 233-237). However, the recently concluded clinical trial of 5-MeO-DMT in TRD patients showed no evidence of hypomania induction.
5-MeO-DMT can induce peak experiences, i.e., experiences characterized by an emotional perspective shift, which is described as “loss of ego” which often culminates in an overwhelming sense of “oneness with the universe”, more rapidly than other psychedelics and has a short duration of acute psychedelic effects (5 to 30 minutes after intravenous injection compared with several hours for e.g. oral psilocybin and oral LSD). These characteristics of 5-MeO-DMT are associated with an improved therapeutic profile which can be explained by specific alterations of Resting State Network (RSN) activity under 5-MeO-DMT treatment.
Furthermore, 5-MeO-DMT is a 5-HT7 receptor agonist showing high affinity towards the receptor. The inventors determined, using recombinant human 5-HT7 receptor, [3H]LSD as a radio ligand and serotonin to estimate non-specific binding, a Ki of 2.3 nM.
Thus, besides the 5-HT1A and 5-HT2A receptors discussed above, 5-MeO-DMT also interacts with the 5-HT7 receptor. 5-MeO-DMT act as an agonist on this receptor and shows a high (nanomolar) binding affinity.
The 5-HT7 receptor has a role in neurogenesis, synaptogenesis and dendritic spine formation. It is, among other things, associated with central processes such as learning and memory, with sleep regulation and circadian rhythm and with nociception.
The 5-HT7 receptor is in particular expressed in the spinal cord, raphe nuclei, thalamus, hypothalamus including the suprachiasmatic nucleus, hippocampus, prefrontal cortex, striatal complex, amygdala and in the Purkinje neurons of the cerebellum.
The suprachiasmatic nucleus is the central pacemaker of the circadian timing system. It coordinates circadian rhythms in various brain regions. Disruption of this coordination will result in disease states, in particular disease states involving sleep disturbance. In patients suffering from sleep disturbance resting state functional connectivity analysis reveals alterations in functional connectivity between the suprachiasmatic nucleus and regions within the default mode network.
The expression of the 5-HT7 receptor in the suprachiasmatic nucleus corresponds to the function of the receptor in regulation of sleep/wake cycles. The inventors consider that this allows treatment of patients suffering from sleep disturbance by 5-MeO-DMT which acts on the receptor.
The inventors consider that binding of 5-MeO-DMT to the 5-HT7 receptor as one mediator of the pharmacological effects of 5-MeO-DMT, which involve functional connectivity “resets” of networks and neuroplasticity effects, contributes to the beneficial effects of 5-MeO-DMT in the treatment of patients suffering from sleep disturbance.
The inventors further consider that binding of 5-MeO-DMT to the 5-HT7 receptor as well as to the 5-HT1A receptor as two mediators of effects exerted by 5-MeO-DMT, which include functional connectivity “resets” of networks and neuroplasticity effects, allows achieving beneficial effects also in patients suffering from other symptoms or conditions, such as cognitive dysfunction, anxiety, psychomotor retardation, negative thinking or social/emotional withdrawal. This is supported by the clinical results demonstrated in studies referred to herein.
Another feature of 5-MeO-DMT is its short half-life.
5-MeO-DMT is mainly inactivated through a deamination pathway mediated by monoamine oxidase A, and it is O-demethylated by cytochrome P450 2D6 (CYP2D6) enzyme.
The inventors investigated pharmacokinetic properties of 5-MeO-DMT and observed rapid absorption and distribution of inhaled 5-MeO-DMT, with maximum concentrations and pharmacological effects observed during and immediately after dosing.
An analysis of the pharmacokinetic properties of 5-MeO-DMT after inhalation shows a very rapid decline of the plasma concentration. Already 10 minutes after administration, the concentration drops to 10% of Cmax or below; after 2 hours, it is 1% of Cmax or below; after 3 hours, 5-MeO-DMT is no longer detectable in the plasma. This applies over the whole dose range tested (6 mg, 12 mg, 18 mg). No accumulation is observed upon repeated administration within a time frame of 1 to 4 hours. Uptitration as disclosed herein will not lead to accumulation and thus not to higher plasma concentrations, for instance, 10 minutes, 2 hours, or 3 hours after administration.
The properties of 5-MeO-DMT make the compound especially suitable for the treatment of anxiety, in particular for patients suffering from a mental disorder or a nervous system disorder, or a medical health condition leading to an associated mental or nervous system condition; in a patient suffering from sleep disturbance, for instance, insomnia; in a patient suffering from an unspecified neurocognitive disorder.
The properties of 5-MeO-DMT also allow specific dosage regimens, as discussed in more detail below.
According to the invention, isotopic variants of 5-MeO-DMT and pharmaceutically acceptable salts thereof can also be used. When reference is made to the use of 5-MeO-DMT or a pharmaceutically acceptable salt thereof, the use of isotopic variants is also contemplated.
These variants are in particular deuterated forms of 5-MeO-DMT and pharmaceutically acceptable salts of such forms.
Deuterated forms of 5-MeO-DMT are forms having a higher deuterium content than expected based on the natural abundance of this isotope.
Deuterated forms of 5-MeO-DMT are in particular forms wherein deuterium has been introduced at one or more defined hydrogen positions.
Examples of deuterated forms of 5-MeO-DMT include, without limitation, 1-deuterio-2-(5-methoxy-1H-indol-3-yl)-N,N-dimethylethanamine, 1,1-dideuterio-2-(5-methoxy-1H-indol-3-yl)-N,N-dimethylethanamine, 1,1,2,2-tetradeuterio-2-(5-methoxy-1H-indol-3-yl)N,N-dimethylethanamine, and N,N-dimethyl-2-[5-(trideuteriomethoxy)-1H-indol-3-yl]ethanamine.
Further examples include forms of 5-MeO-DMT wherein deuterium has been introduced at one or more hydrogen positions of the N-bound methyl groups. Still further examples include forms of 5-MeO-DMT wherein one or more deuterium atoms replace hydrogen atoms of the indole ring system. It is moreover noted that combinations of the above substitution patterns are also contemplated.
Preparation methods for these compounds are known in the art.
According to the invention, mixtures of deuterated forms of 5-MeO-DMT, mixtures of one or more deuterated form with non-deuterated 5-MeO-DMT, pharmaceutically acceptable salts of deuterated forms of 5-MeO-DMT, mixture of such salts as well as mixtures of salts of deuterated and non-deuterated 5-MeO-DMT can also be used.
Further according to the invention, deuterated 5-MeO-DMT and salts of deuterated 5-MeO-DMT are used in amounts that are equimolar to the amounts of the corresponding non-deuterated forms.
According to the invention, prodrugs of 5-MeO-DMT and pharmaceutically acceptable salts of such prodrugs can also be used. Such prodrugs of 5-MeO-DMT can be metabolically converted to 5-MeO-DMT. Thus, when reference is made to the use of 5-MeO-DMT or a pharmaceutically acceptable salt thereof, his can be replaced by a 5-MeO-DMT prodrug or a salt thereof.
In suitable prodrugs, the hydrogen in position 1 of the indole moiety is substituted by an organic moiety which can be split off after administration.
Examples of suitable organic moieties are —C(O)OR1, —C(O)R2, —CH(R3)OR4, —C(O)OCH(R3)OC(O)R4, —C(O)OCH(R3)OC(O)OR4, —CH(R3)C(O)R4, —CH(R3)OC(O)R4, —CH(R3)OC(O)OR4, wherein each of R1, R2, R3, and R4 is independently hydrogen, alkyl, heteroalkyl, cycloalkyl, heterocyclylalkyl, aryl, or heteroaryl, wherein each alkyl, heteroalkyl, cycloalkyl, heterocyclylalkyl, aryl, and heteroaryl is independently substituted or unsubstituted.
Preferred examples of organic moieties are —CH(R3)OC(O)R4 and —C(O)OR1, wherein R1, R3, and R4 are defined as above.
Prodrugs, especially those of the above structure, can also be used on the form of pharmaceutically acceptable salts.
Specific examples of prodrugs are 5-MeO-DMT carboxy-isopropyl valinate, preferably in salt form, in particular as ditrifluoroacetate (1-(((S)-2-amino-3-methylbutanoyl)oxy)-2-methylpropyl 3-(2-(dimethylamino)ethyl)-5-methoxy-1H-indole-1-carboxylate di-trifluoroacetate) and 5-MeO-DMT methyl pivalate (3-(2-(dimethylamino)ethyl)-5-methoxy-1H-indol-1-yl)methyl pivalate).
Preparation methods for prodrugs as discussed herein are known in the art.
According to the invention, the Tmax value of the metabolite 5-MeO-DMT as measured in male Sprague-Dawley (SD) rats following oral dosing of the prodrug at 10 mg/kg is preferably 1 hour or less, more preferably 0.7 hours or less and in particular 0.5 hours or less.
Further according to the invention, prodrugs of 5-MeO-DMT and salts of prodrugs of 5-MeO-DMT are used in amounts that are equimolar to the amounts of the corresponding non-prodrug forms.
The therapeutically effective amount of 5-MeO-DMT is administered by intravenous administration, by intramuscular administration or by subcutaneous administration. Administration via these routes can assure a rapid onset of action. A most preferred route of administration is administration via the intravenous route, i.e. by intravenous injection.
5-MeO-DMT can be employed as a pharmaceutically acceptable salt, preferably the hydrobromide salt, or in the form of a formulation for administration via injection, examples of excipients and vehicles for such formulations being known in the art.
The present invention also provides dose ranges, particular doses as well as dosing regimens (administration schemes) and appropriate routes of administration.
The invention is in part based on the inventors' conclusion that the occurrence of a peak psychedelic experience during the acute phase after administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof is driving its therapeutic benefit in patients suffering from anxiety, in particular one or more of the aspects defined above, either in a causal relationship or at least as a surrogate behavioral marker for the underlying unknown therapeutic mechanism.
Consequently, achieving peak experiences more rapidly, in a larger proportion of patients and with better reproducibility in an individual patient, compared with previously tested psychedelic agents, dosing regimens and administration routes, will lead to a better therapeutic profile.
Further, the present invention also relies on the short duration of action of 5-MeO-DMT and the absence of relevant tolerance (i.e., the absence of diminished or no psychedelic effects after re-administration), as a basis for enabling a dosing regimen with frequent re-administrations (such as more than once daily, or daily), which are designed to increase the rate of occurrence of peak experiences, thereby increasing the therapeutic benefit. Such repeat administrations within short time also allow an intraindividual dose-optimization which reduces the risk of overdosing, which may otherwise lead to somatic side effects, such as the serotonin syndrome, negative psychic reactions, such as flashbacks of the experience at later timepoints, induction of mania or hypomania or to less meaningful psychedelic experiences with few or no memories of the altered state (so-called “white-outs”). Further, starting with a low dose allows familiarization of the patient with the psychedelic experience in general, and allows preparation for the more intense symptoms to occur at the higher doses, which will positively influence the experience at those higher doses. Also, the prospect of being able to initiate treatment with a low dose will increase patient acceptance of the therapeutic approach and improve overall compliance rates on the patient population level.
Frequent re-administrations of a serotonergic psychedelic with the aim to increase the rate and tailor the reproducibility of peak experiences and to improve the therapeutic effect, reduce the side effects and improve the compliance rates may not be possible with other psychedelics, due to the late onset and long duration of psychedelic effects and due to the rapid development of tolerance (i.e. diminished or no psychedelic effects after re-administration) which can last for several days.
A patient as defined herein who suffers from anxiety is treated by administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof.
In a preferred embodiment, the 5-MeO-DMT is administered as a monotherapy, i.e., the patient does not receive any other treatment for so anxiety.
The dosage amount of 5-MeO-DMT administered to a patient, as defined herein, suffering from anxiety, is in the range of about 1 mg to about 10 mg, or any amount of range therein and is administered in the form of a formulation for administration based on a pharmaceutically acceptable salt of 5-MeO-DMT, such as the hydrobromide salt, which weight amount can be calculated from the stated weight amounts of the 5-MeO-DMT free base, assuming that equimolar amounts are used. Useful specific amounts of 5-MeO-DMT are e.g. about 1 mg, about 2 mg, about 3 mg, about 4 mg, about 5 mg, about 6 mg, about 7 mg, about 8 mg, about 9 mg, and about 10 mg. Note that in this specification, when ranges are set forth, such as “about 1 mg to about 10 mg,” the inventor contemplates all discrete values within that range, some of which are specifically mentioned, but all of which are not-simply for the purpose of brevity.
In preferred embodiments the improved methods for the treatment of a patient, as defined herein, suffering from anxiety, with a therapeutically effective amount of 5-MeO-DMT, comprise the occurrence of a clinical response not later than about 2 hours after administration of 5-MeO-DMT.
In preferred embodiments the improved methods for the treatment of a patient, as defined herein, suffering from anxiety, with a therapeutically effective amount of 5-MeO-DMT, comprise the persistence of a clinical response, including a clinical response which occurred not later than about 2 hours after administration of 5-MeO-DMT, until at least about 6 days after the last administration of 5-MeO-DMT, preferably until at least about 14 days after the last administration of 5-MeO-DMT, more preferably until at least about 28 days after the last administration of 5-MeO-DMT.
In preferred embodiments the improved methods for the treatment of a patient, as defined herein, suffering from anxiety, with a therapeutically effective amount of 5-MeO-DMT comprise the administration of more than a single dose of 5-MeO-DMT.
In a preferred embodiment this more than a single dose of 5-MeO-DMT is administered to a patient in one or more treatment blocks, each block consisting of 2 to 7 administrations, with not less than about 1 hour and not more than about 24 hours between each administration within each treatment block, and not less than about 6 days between the end of one treatment block and the start of the next treatment block.
In an even more preferred embodiment this more than a single dose of 5-MeO-DMT is administered to a patient in one or more treatment blocks, each block consisting of 1 to 3 administrations, with about 24 hours between each administration within each treatment block, and not less than about 6 days between the end of one treatment block and the start of the next treatment block.
In a most preferred embodiment this more than a single dose of 5-MeO-DMT is administered to a patient in one or more treatment blocks, each block consisting of 1 to 3 administrations, with about 1 to 4 hours, preferably 1 to 2 hours, between each administration within each treatment block, and not less than about 6 days between the end of one treatment block and the start of the next treatment block.
In an embodiment the dosage amount of the 5-MeO-DMT administered to an individual patient in each of the administrations and in each of the treatment blocks is constant for that individual patient and is selected from about 1 mg to about 10 mg.
In a preferred embodiment the dosage amount of the 5-MeO-DMT administered to an individual patient is selected from about 1 mg to about 2 mg for the first administration within each treatment block, and then increases with each subsequent administration within each treatment block until the earlier of 10 mg being reached or all administrations within that treatment block being administered.
In an even more preferred embodiment the dosage amount of the 5-MeO-DMT administered to an individual patient is selected from about 1 mg to about 2 mg for the first administration within each treatment block, and then increases with each subsequent administration within each treatment block until the earlier of 10 mg being reached or all administrations within that treatment block being administered or the patient having experienced a peak psychedelic experience or the supervising physician having decided that further dose increases are inappropriate based on observed side effects.
For embodiments where the dosage amount increases for subsequent administrations, the dosage amount for the next administration is determined by adding about 0.25 mg to about 3 mg, preferably about 0.5 mg to about 3 mg to the dosage amount of the prior administration. For example, if the dosage amount of the first administration was 1 mg and the dosage amount increase is 3 mg, unless one of the previously mentioned stopping criteria has been reached, then the dosage amount of the second administration will be 4 mg. Preferably, the dosage amount for the third administration will be 7 mg.
In a preferred embodiment the dosage amount of the 5-MeO-DMT administered to an individual patient in each treatment block is selected from about 1 mg to about 3 mg for the first administration, and then increased, unless the patient has already experienced a peak psychedelic experience within that treatment block or the supervising physician has decided that further dose increases are inappropriate based on observed side effects, to a dosage selected from about 4 mg to about 6 mg for the second administration, and from about 7 mg to about 9 mg for the third administration. Useful specific amounts for the first, second and third administration are e.g. about 2 mg, about 5 mg, and about 8 mg.
In an additional preferred embodiment, the dosage amount of the 5-MeO-DMT administered to an individual patient in each treatment block is selected from about 0.5 mg to about 1.5 mg for the first administration, and then increased, unless the patient has already experienced a peak psychedelic experience within that treatment block or the supervising physician has decided that further dose increases are inappropriate based on observed side effects, to a dosage selected from about 1.5 mg to about 2.5 mg for the second administration, and from about 2.5 mg to about 3.5 mg for the third administration. Useful specific amounts for the first, second and third administration are e.g. about 1 mg, about 2 mg, and about 3 mg.
In a further preferred embodiment the dosage amount of the 5-MeO-DMT administered to an individual patient is selected from about 1 mg to about 2 mg for the first administration of the first treatment block, and then increases with each subsequent administration within that first treatment block until the earlier of 10 mg being reached or all administrations within that treatment block being administered or the patient having experienced a peak psychedelic experience or the supervising physician having decided that further dose increases are inappropriate based on observed side effects, with that highest dosage in that first treatment block being used as the dosage for all subsequent treatment blocks and administrations within those subsequent treatment blocks. For example, if the highest dosage in the first treatment block was 8 mg because the patient experienced a peak psychedelic experience at that dose, then the dosage for all subsequent treatment blocks and administrations within those subsequent treatment blocks will be 8 mg.
In a particularly preferred embodiment the dosage amount of the 5-MeO-DMT administered to an individual patient is selected from about 1 mg to about 3 mg for the first administration of the first treatment block, and then increased, unless the patient has already experienced a peak psychedelic experience within that treatment block or the supervising physician has decided that further dose increases are inappropriate based on observed side effects, to a dosage selected from about 4 mg to about 6 mg for the second administration of the first treatment block, and from about 7 mg to about 9 mg for the third administration of the first treatment block, with the highest dosage in that first treatment block being used as the dosage for all subsequent treatment blocks and administrations within those subsequent treatment blocks. Useful specific amounts for the first, second and third administration in the first treatment block are e.g. about 2 mg, about 5 mg, and about 8 mg.
In a particularly preferred embodiment the dosage amount of the 5-MeO-DMT administered to an individual patient is selected from about 0.5 mg to about 1.5 mg for the first administration of the first treatment block, and then increased, unless the patient has already experienced a peak psychedelic experience within that treatment block or the supervising physician has decided that further dose increases are inappropriate based on observed side effects, to a dosage selected from about 1.5 mg to about 2.5 mg for the second administration of the first treatment block, and from about 2.5 mg to about 3.5 mg for the third administration of the first treatment block, with the highest dosage in that first treatment block being used as the dosage for all subsequent treatment blocks and administrations within those subsequent treatment blocks. Useful specific amounts for the first, second and third administration in the first treatment block are e.g. about 1 mg, about 2 mg, and about 3 mg.
It is understood that a pharmaceutically acceptable salt of 5-MeO-DMT is preferably used in all of the above dosing regimen, and that the appropriate weight amounts of a salt to be administered can be calculated from the stated weight amounts of the free base, assuming that equimolar amounts are used.
According to the invention, 5-MeO-DMT is preferably not administered together with a MAO inhibitor.
The occurrence of a “peak psychedelic experience” in a patient can be identified through achievement of at least 60% of the maximum possible score in each of the four subscales (mystical, positive mood, transcendence of time and space, and ineffability) of the 30-item revised Mystical Experience Questionnaire (MEQ-30) (as described in Barrett FS, J Psychopharmacol. 2015; 29(11):1182-90).
The occurrence of a “peak psychedelic experience” in a patient can also be identified through achievement of at least 60% of the maximum possible score of the Oceanic Boundlessness (OBN) dimension of the Altered States of Consciousness (ASC) questionnaire (as described in Roseman L et al., Front Pharmacol. 2018; 8:974).
In accordance with the invention, the occurrence of a “peak psychedelic experience” in a patient is preferably identified through achievement of a score of at least 75 in the Peak Experience Scale (PES) Total Score, also referred to as the Peak Psychedelic Experience Questionnaire (PPEQ), which averages answers scored by the patient from 0 to 100 for the following three questions: 1. How intense was the experience; 2. To what extent did you lose control; 3. How profound (i.e. deep and significant) was the experience?
According to the invention, anxiety occurring in a patient suffering from an anxiety disorder, or another mental disorder or nervous system disorder associated with anxiety, can be treated. Moreover, anxiety occurring in a patient suffering from sleep disturbance, for instance, insomnia can be treated.
In patients suffering from anxiety in association with another mental disorder or nervous system disorder or sleep disturbance, for instance, insomnia, a treatment of anxiety according to the invention leads to an improvement of the condition with which the anxiety is associated.
Treatment according to the invention is by administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof.
5-MeO-DMT administered to a patient disrupts established functional connectivity patterns within and/or between resting state networks. This disruption leads to a reset of the pathological ill-connected connections as the networks reconnect. New, healthy functional connections are established with persistent effects.
Thus, according to the invention, influencing those networks by a therapy as described herein will lead to an improvement of the anxiety and, if the patient treated suffers from another mental disorder or nervous system disorder associated with anxiety, also of that disorder; if the patient treated suffers from sleep disturbance, for instance, insomnia, also of the sleep disturbance, for instance, insomnia.
To further support the clinical application of 5-MeO-DMT in patients suffering from anxiety, the inventors assessed clinical data relating to the use of 5-MeO-DMT in patients treated because of mental disease and noted particular improvements in anxiety which is typically also observed in patients with other disorders.
The data stem from a recently completed clinical trial investigating the use of 5-MeO-DMT in the treatment of patients diagnosed with Treatment Resistant Depression (TRD; see also the examples section below). While TRD is a specific condition, the inventors determined, as discussed in detail below, that certain clinical observations are made in the trial are relevant for devising a treatment for anxiety disorders and other conditions which are associated with anxiety.
In the clinical trial, 5-MeO-DMT was administered via inhalation (as described in more detail in the example section below). Patients were assigned to different groups. In the context of the present invention, the group who received a single, 12 mg dose and the group who underwent an intra-day individualized dosing regimen (IDR) that allowed for multiple, escalating doses (6 mg, 12 mg and 18 mg) within a single day, driven by the intensity of the patient-reported psychedelic experience are of interest.
The data gathered include the assessment of the treated patients against several scales including the Montgomery-Åsberg Depression Rating Scale (MADRS) and the Brief Psychiatric Rating Scale (BPRS). While the focus of the trial was on demonstrating treatment efficacy through improvements in overall MADRS score, the inventors focused on the items comprising the various rating scales and noticed that particular subscore items, like items related to anxiety, are relevant for other conditions in which anxiety is based on similarly altered functional connectivity within and/or between resting state networks.
Multiple patients within the recruited cohort displayed significant improvements, a result that confirms the inventors' finding that 5-MeO-DMT is a compound suitable for treating patients presenting with these symptoms.
More in particular, an aspect which can be treated by administration of 5-MeO-DMT, is anxiety. 5-MeO-DMT can be administered to patients to reduce or eliminate anxiety in said patients.
The BPRS item that is of particular relevance in this context is “anxiety”. This item relates to reported apprehension, tension, fear, panic or worry. Possible scores are:
In the study group receiving the individualized dosing regimen, the aggregated score for the BPRS item “anxiety” across all 8 patients was 37 at base line.
After 3 hours, it was reduced to 19 which corresponds to an improvement of 18 points or 49%. At day 1 after treatment, it was reduced to 16 which corresponds to an improvement of 21 points or 57%. At day 7 after treatment, it was reduced to 17 which corresponds to an improvement of 20 points or 54%.
In the 12 mg group, the aggregated score for the BPRS item “anxiety” across all 4 patients was 25 at base line.
After 3 hours, it was reduced to 11 which corresponds to an improvement of 14 points or 56%. At day 1 after treatment, it was reduced to 6 which corresponds to an improvement of 19 points or 76%. At day 7 after treatment, it was reduced to 6 which corresponds to an improvement of 19 points or 76%.
The inventors conclude that 5-MeO-DMT can be used to treat anxiety in patients, such as patients suffering from an anxiety disorder and patients suffering from a mental or nervous system disorder with associated anxiety.
Consequently, according to the invention, the treatment of a patient suffering from anxiety with 5-MeO-DMT or a pharmaceutically acceptable salt thereof reduces or eliminates anxiety.
The MADRS item “inner tension” represents feelings of ill-defined discomfort, edginess, inner turmoil, mental tension mounting to either panic, dread or anguish. It is rated according to intensity, frequency, duration and the extent of reassurance called for.
A score of 0 is assigned if the patient is placid and there is only fleeting inner tension. A score of 2 is assigned if there are occasional feelings of edginess and ill defined discomfort. The score is 4 if there are continuous feelings of inner tension or intermittent panic which the patient can only master with some difficulty. The score is 6 in case of unrelenting dread or anguish and overwhelming panic.
In the above indicated trial involving TRD patients, in the study group receiving the individualized dosing regimen, the aggregated score for the MADRS item “inner tension” across all 8 patients was 26 at base line. After 2 hours, it was reduced to 11 which corresponds to an improvement of 15 points or 58%. At day 1 after treatment, it was reduced to 6 which corresponds to an improvement of 20 points or 77%. At day 7 after treatment, it was reduced to 12 which corresponds to an improvement of 14 points or 54%.
In the 12 mg group, the aggregated score for the MADRS item “inner tension” across all 4 patients was 13 at base line. After 2 hours, it was reduced to 2 which corresponds to an improvement of 11 points or 85%. At day 1 after treatment, it was reduced to 3 which corresponds to an improvement of 10 points or 77%. At day 7 after treatment, it was reduced to 5 which corresponds to an improvement of 8 points or 62%.
These results further support the inventors' conclusion that a treatment according to the invention reduces or eliminates symptoms of anxiety.
A treatment according to the invention leads to a clinical response in a patient suffering from anxiety symptoms which is reflected by an at least 50% decrease of the HAM-A score, compared to the respective score prior to treatment, about 2 hours after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof; on day 1, for instance after about 24 hours; on day 7; on day 14; and/or on day 28 after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof.
A clinical response in a patient suffering from anxiety symptoms, as reflected by at least 50% decrease of the HAM-A score, compared to the respective score prior to treatment, occurs not later than about 2 hours after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof. The clinical response in a patient suffering from anxiety symptoms, as reflected by at least 50% decrease of the HAM-A score, preferably persists until at least 6 days; in particular until at least 14 days; more preferably until at least 28 days after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof.
A remission of the anxiety symptoms in a patient suffering from anxiety symptoms is reflected by a HAM-A score of 7 or less about 2 hours after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof; on day 1, for instance after about 24 hours; on day 7; on day 14; and/or on day 28 after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof.
A remission of the anxiety symptoms in a patient suffering from anxiety symptoms, as reflected by a HAM-A score of 7 or less, occurs not later than about 2 hours after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof. The remission of the anxiety symptoms in a patient suffering from anxiety symptoms, as reflected by a HAM-A score of 7 or less, preferably persists until at least 6 days; in particular until at least 14 days; more preferably until at least 28 days after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof.
Consequently, according to the invention, the treatment of a patient suffering from anxiety with 5-MeO-DMT or a pharmaceutically acceptable salt thereof reduces or eliminates anxiety.
Sleep disturbance refers to conditions, whether idiopathic or occurring in the context of a medical condition such as for example a mental disorder or a nervous system disorder, or a medical health condition leading to an associated mental or nervous system condition, that affect sleep quality, timing, or duration. It impacts a person's ability to properly function while the person is awake and in particular compromises cognitive function and also gives rise to anxiety.
There are two fundamental types of sleep: rapid eye movement (REM) sleep and non-REM sleep. Non-REM sleep can be divided into four stages (I-IV). These non-REM stages correspond to an increasing depth of sleep. Non-REM and REM sleep alternate during each of the four to five cycles of normal human sleep each night. During the earlier proportion of the night, non-REM sleep is deeper and occupies a disproportionately large amount of time, particularly within the first cycle of sleep. As the night progresses, non-REM sleep becomes shallow and more of each cycle is allocated to REM sleep.
Normal healthy sleep consists of different phases as outlined above that proceed in successive, tightly regulated order through the night.
Disruption of this tight regulation results in sleep disturbances.
Common forms of sleep disturbances encompass disorders of initiating and maintaining sleep (insomnia), disorders of excessive somnolence (hypersomnia), disorders of sleep-wake schedule (circadian rhythm disorders), dysfunctions associated with sleep, sleep stages, or partial arousals (parasomnia), disorders characterized by respiratory disturbance during sleep (sleep-related breathing disorders) and disorders characterized by abnormal movements during sleep (sleep-related movement disorders).
Insomnia is a sleep disturbance where people have difficulty falling or staying asleep. People with insomnia have difficulty falling asleep; wake up often during the night and have trouble going back to sleep; wake up too early in the morning; have unrefreshing sleep; and/or have at least one daytime problem such as fatigue, sleepiness, problems with mood, concentration, accidents at work or while driving, etc. due to poor sleep.
Hypersomnia is characterized by excessive daytime sleepiness, and/or prolonged nighttime sleep. Sleep drunkenness is also a symptom found in hypersomnia patients. It is a difficulty transitioning from sleep to wake. Individuals experiencing sleep drunkenness report waking with confusion, disorientation, slowness and repeated returns to sleep.
Circadian rhythm disorders are characterized by chronic or recurring sleep disturbances due to alterations of the individual's internal circadian rhythm or due to misalignments between their circadian rhythm and their desired or required work or social schedule. This dyssynchrony may be transient or persistent. The ensuing clinical picture combines elements of both insomnia and hypersomnia. Sleep periods are usually shortened and disrupted, performance during the desired waking state is impaired, and temporary opportunities to revert to a regular sleep schedule are unsuccessful.
Parasomnia designates various forms of sleep disturbance characterized by abnormal behavioural or physiological activity (such as sleepwalking or nightmares) that people experience prior to falling asleep, while asleep, or during the arousal period between sleep and wakefulness. There are considerable variations in terms of characteristics, severity, and frequency. Parasomnia may compromise the quality of sleep.
Sleep-related breathing disorders are characterized by abnormal and difficult respiration during sleep. Respiration is a complex process that relies heavily on the coordinated action of the muscles of respiration and the (control center in the) brain. One form of a sleep-related breathing disorder is central sleep apnoea. It occurs when the brain stops sending signals that control breathing, for instance, based on an underlying health condition. Central sleep apnoea has a potentially serious impact on sleep and the balance of oxygen and carbon dioxide in the blood. The reduction of airflow leads to intermittent hypoxia which in leads to sleep fragmentation due to microarousals or awakenings. A consequence can be excessive daytime sleepiness.
In sleep-related movement disorders repetitive, relatively simple, usually stereotyped, movements interfere with sleep or its onset. The most common of these are restless leg syndrome (RLS) and periodic limb movement disorder (PLMD).
Not getting the proper amount or quality of sleep may lead to personality changes and may not only exacerbate existing mental illness, but also be a trigger for the development of mental illness.
Sleep disturbances such as insomnia are highly comorbid with anxiety disorders. Insomnia and anxiety may be mutually influencing conditions as insomnia often precedes the development of anxiety, but anxiety symptoms are associated with abnormal sleep wake cycles and can therefore lead to disordered sleep. For instance, excess worry and fear make it harder to fall asleep and stay asleep through the night.
Anxiety has an influence on sleep cycles, as anxiety and pre-sleep rumination affect rapid eye movement (REM) sleep, involving the most vivid dreaming. More disturbing dreams are provoked and thus, a higher likelihood of sleep disruption arises.
Further, distress about falling asleep can itself complicate matters, creating a sleep anxiety that reinforces a person's sense of dread and preoccupation. These negative thoughts about going to bed, a type of anticipatory anxiety, can create challenges to healthy sleep schedules and routines.
Sleep deprivation can worsen anxiety, spurring a negative cycle involving insomnia and anxiety.
Abnormal function of the Locus Coeruleus-Norepinephrine System (LC-NS), an area in the brainstem critical for waking and attention, is implicated in insomnia and has been associated with anxiety symptoms in patients with chronic insomnia.
Poor sleep has a significant impact on functional impairment. Patients suffering from an anxiety disorder and sleep disturbance experience significantly worse mental health-related quality of life and increased disability relative to those with the anxiety disorder alone.
Sleep disturbances are very common in patients with Social Anxiety Disorder, Agoraphobia, Phobia and Substance/Medication Induced Anxiety Disorder, given the bidirectional relationship between sleep disturbances (mainly insomnia) and anxiety.
Separation Anxiety Disorder is also associated with sleep disturbances. Sleep disturbance is even part of the diagnostic criteria of Separation Anxiety Disorder. Sleep disturbances in patients suffering from Separation Anxiety Disorder include nightmares, difficulty falling or staying asleep, early waking, and parasomnias.
For Generalized Anxiety Disorder, sleep disturbance, in particular including difficulty falling or staying asleep, or restless unsatisfying sleep, is a key feature. Sleep disturbance is associated with significant disability in GAD. In the DSM-5 criteria, sleep disturbance is one of 6 symptoms of which at least 3 need to be present for a certain period of time to satisfy a diagnosis of GAD.
In patients with Panic Disorder, sleep disturbances (particularly insomnia and hypersomnia) are very common. Individuals suffering from Panic Disorder may also experience nocturnal panic attacks which are distinguished from night terrors. Nocturnal panic attacks can occur without a trigger and often result in difficulty falling back asleep.
Treatment of sleep disturbance varies depending on the type and underlying cause. Maintenance of good sleep hygiene, a healthy sleep environment, and a consistent sleep-wake schedule are often considered as first-line treatment. If not successful, treatment also involves pharmacotherapy or psychotherapy.
Available treatments are not successful in all patients, may be associated with side effects and/or require treatment over a long period of time to achieve a relevant treatment effect.
In patients suffering from sleep disturbance in association with a mental disorder or a nervous system disorder known treatments of the mental or nervous system disorder do not necessarily improve the sleep disturbance.
For instance, sleep disturbance is frequently associated with mental disorders, such as depression. However, treatment of depression does not necessarily lead to an improvement of the concomitant sleep disturbances. While most antidepressants have been proven to influence the sleep architecture, some classes of antidepressants improve sleep, but others may cause sleep impairment.
To assess sleep, parameters such as sleep duration, sleep architecture, sleep latency, and the frequency and duration of awakenings throughout the night can be measured. The quantitative metrics may be measured using objective methods, including polysomnography, actigraphy, and the determination of sleep latency, or by way of self-reported measures (questionnaires).
Polysomnography is a technique requiring that a patient is monitored overnight at a specialized clinic. A variety of functions are measured throughout the night, including eye movements, brain and muscle activity, respiratory effort and airflow, blood oxygen levels, body positioning and movements, snoring, and heart rate.
Another quantitative measurement is actigraphy. An actimetry sensor is worn to measure motor activity, which is recorded continually and used to assess sleep-wake cycles. This technique allows the patient to continue normal routines while the required data are being recorded in natural sleep environment.
Sleep latency can be measured by the multiple sleep latency test (MSLT). This test provides an objective measure to determine how long it takes a person to fall asleep across a multiplicity of test naps. An average sleep latency of approximately 10 minutes is considered to be normal; less than eight minutes is indicative of sleep disturbance/excessive daytime sleepiness. Accompanying analysis of brain activity can assist in the further diagnose of the sleep disturbance.
Sleep-rating questionnaires capture ratings of components of sleep quality, such as perceptions of sleep depth, rousing difficulties, and restfulness after sleep, in addition to other factors that could affect sleep quality, such as comorbid conditions and medication use. Since anxiety and sleep disturbance are linked, anxiety can be part of the assessment.
The evaluation of the qualitative aspects of sleep experience is important, as sleep complaints can often persist despite normal values for quantitative measures of sleep.
Questionnaires not only facilitate a quick and accurate assessment of a complex clinical problem, but they are potentially also helpful for tracking a patient's progress. Thus, self-reported sleep questionnaires completed by patients are an important mainstay for the assessment of sleep disturbance in clinical practice.
Various sleep quality indexes are known. The following indexes include examples of questionnaires to assess sleep in general and questionnaires to assess in particular insomnia, hypersomnia, circadian rhythm disorders and parasomnia, respectively. The invention is, however, not limited to the use of a particular index or questionnaire.
Some questionnaires rely on recall periods (recall windows) of several days or even weeks. While this may be appropriate for diagnosing sleep disturbances, it is not always appropriate for assessing treatment effects, in particular rapid onset of effect after treatment. For several of the questionnaires the recall period can be modified so that the scores obtained reflect a period after treatment. Questionnaires specifically discussed herein to assess effects of a treatment on sleep in patients suffering from specific conditions rely on a recall period that does not start earlier than the time point when acute psychedelic experiences have subsided after the last administration. To meet this criterion, the normally applied recall period is modified if necessary.
Sleep quality in general can be assessed, for instance, with the Sleep Quality Scale (SQS) and the Sleep-50 questionnaire.
The Sleep Quality Scale (SQS) is an all-inclusive assessment tool to achieve a general, efficient measure suitable for evaluating sleep quality in a variety of patient and research populations. Individual questions on daytime symptoms, such as attention, concentration difficulties or memory problems (Item 15, “Poor sleep makes hard for me to think”, item 19 “Poor sleep causes me to make mistakes at work”, item 21 “Poor sleep makes me forget things more easily”, item 22 “Poor sleep makes it hard to concentrate at work”), restoration after sleep, problems initiating and maintaining sleep, difficulty waking, and sleep satisfaction can be scored from 0 (“rarely”)-3 (“almost always”), with higher scores being indicative for more acute sleep problems (A. Shahid et al. (eds.), STOP, THAT and One Hundred Other Sleep Scales, Springer Science+Business Media, LLC 2012). Respondents are asked to report their experience over the previous month or another appropriate recall window.
Treatment success is indicated by a decrease of the score.
The SLEEP-50 questionnaire consists of 50 items designed to screen for various kinds of sleep disturbance in the general population. The scale consists of nine subscales, reflecting some of the most common disorders and complaints related to sleep and the factors required for diagnosis such as sleep apnoea, insomnia, narcolepsy, restless legs/periodic leg movement disorder, circadian rhythm sleep disorder, sleepwalking, nightmares, factors influencing sleep, and the impact of sleep complaints on daily functioning. For each item, respondents are provided with a scale ranging from 1 (“not at all”) to 4 (“very much”) and are asked to indicate the extent to which the statement has matched their experience over the previous month or another appropriate recall window.
For diagnosing a sleep disorder not only the specific subscale (e.g., insomnia) must exceed a certain cut-off point, but respondents must also meet a cut-off of at least 3 or 4 (“rather much” or “very much”, respectively) on the subscale evaluating the impact of sleep complaints on daily functioning (Spoormaker et al. Initial validation of the SLEEP-50 questionnaire. Behav Sleep Med. 2005; 3(4):227-46).
Treatment success is indicated (i) by a decrease of the score, preferably (ii) by a decrease to below the cut-off value.
A common questionnaire assessing sleep disturbance is the Pittsburgh Sleep Quality Index. Other instruments are the insomnia severity index, the Espie sleep disturbance questionnaire and the Patient Reported Outcomes Measurement Information System (PROMIS®) Sleep Disturbance.
The Pittsburgh Sleep Quality Index (PSQI) assesses overall sleep quality and disturbances. The PSQI is a self-rated questionnaire comprising 19 questions. Respondents are asked to indicate how frequently they have experienced certain sleep difficulties over the past month or another appropriate recall window.
The 19 self-rated questions assess a wide variety of factors relating to sleep quality, including estimates of sleep duration and latency and of the frequency and severity of specific sleep-related problems. These 19 items are grouped into seven component scores: (1) subjective sleep quality; (2) sleep latency; (3) sleep duration; (4) habitual sleep efficiency; (5) sleep disturbances; (6) use of sleeping medication; (7) daytime dysfunction.
Each component is assigned a score of 0 to 3. Higher scores indicate more acute sleep disturbances. Detailed Scoring Instructions for the Pittsburgh Sleep Quality Index can be found in the Appendix of Buysse et al. The Pittsburgh Sleep Quality Index: a new instrument for psychiatric practice and research. Psychiatry Res. 1989 May; 28 (2): 193-213.
The seven component scores are then summed to yield one global score, with a range of 0-21 points, “0” indicating no difficulty and “21” indicating severe difficulties in all areas. A global score cut-off of 5 distinguishes poor from good sleepers. A global score >5 indicates that a patient is having severe difficulties in at least two areas, or moderate difficulties in more than three areas.
If treatment outcome is assessed using the PSQI, treatment success is indicated (i) by a decrease of the score, preferably (ii) by a decrease to 5 or below.
The Insomnia Severity Index (ISI) is a short questionnaire relating to subjective sleep quality, severity of symptoms, subjective satisfaction with sleep, the degree to which insomnia interferes with daily functioning (Item 3, “To what extent do you consider your sleep problem to interfere with your daily functioning (e.g. daytime fatigue, ability to function at work/daily chores, concentration, memory, mood, etc).”), how noticeable the respondent feels his or her insomnia is compared to others, and the overall level of distress created by the sleep problem. Individual responses can be scored from 0 (=none) to 4 (=very); a higher total score corresponds to more severe insomnia. A total score of 0-7 indicates “no clinically significant insomnia,” 8-14 means “subthreshold insomnia,” 15-21 is “clinical insomnia (moderate severity),” and 22-28 means “clinical insomnia (severe)” (A. Shahid et al., loc.cit.). The usual recall window for the ISI is two weeks, but other appropriate recall window can also be used herein.
Treatment success is indicated (i) by a decrease of the score, for instance, by >7 points, in particular >8 point; preferably (ii) by a decrease to below the cut-off value for clinically significant insomnia.
The Espie sleep disturbance questionnaire (SDQ) evaluates subjective experiences of insomnia. With ratings on restlessness/agitation, mental overactivity, consequences of insomnia, and lack of sleep readiness, the SDQ is concerned specifically with beliefs about the sources of sleep issues. Respondents use a five-point scale to indicate how often certain statements about insomnia are representative of their experience. 1 means “never true,” while 5 means “very often true.” Higher scores are indicative of more dysfunctional beliefs about the causes and correlates of insomnia (A. Shahid et al., loc. cit.;).
Treatment success is indicated by a decrease of the score.
The Patient-Reported Outcomes Information System (PROMIS®) Sleep Disturbance Instrument is a universal measure to evaluate sleep disturbances. The instrument is available as a long form and 4 different short forms (e.g., 4-, 6-, and 8-items) and assesses self-reported perceptions of sleep quality, sleep depth, and any perceived difficulties related to getting and staying asleep over a 7-day period.
Each item on the measure is rated on a 5-point scale. The raw scores on the items are summed to obtain a total raw score. Total raw scores are then converted into a standardized T-score using conversion tables.
Treatment success is indicated by a decrease of the T-score.
Hypersomnia or hypersomnolence can be assessed by the Epworth Sleepiness Scale, the Stanford Sleepiness Scale, or the Idiopathic Hypersomnia Severity scale.
The Epworth Sleepiness Scale (ESS) evaluates overall daytime sleepiness. The questionnaire asks respondents to rate how likely they are to fall asleep in eight different situations representing a moment of relative inactivity, such as a nap in the afternoon or sitting in a car stopped in traffic. Using a scale of 0-3 (with 0 meaning “would never doze” and 3 meaning “high chance of dozing”), respondents rate their likelihood of falling asleep. Scoring ranges from 0-24; the higher the score, the higher the severity of daytime sleepiness. A cut-off score of 10 identifies daytime sleepiness at a potentially clinical level (A. Shahid et al., loc. cit.).
Treatment success is indicated (i) by a decrease of the score, preferably (ii) by a decrease to 10 or below.
The Stanford Sleepiness Scale is a subjective measure of sleepiness, evaluating sleepiness at specific moments in time. Consisting of only one item, the scale requires respondents to select one of seven statements best representing their current level of perceived sleepiness. A scale from 1 (=Feeling active and vital; alert; wide awake) to 7 (=Almost in reverie; sleep onset soon; lost struggle to remain awake) is used to assess the level of sleepiness (A. Shahid et al., loc. cit.).
Treatment success is indicated by a decrease of the score.
Parasomnias can be evaluated by the Paris Arousal Disorders Severity Scale (PADSS).
The Paris Arousal Disorders Severity Scale (PADSS) is a self-rating scale listing parasomniac behaviours, assessing their frequency and includes an evaluation of consequences (Arnulf et al. A scale for assessing the severity of arousal disorders. Sleep. 2014 Jan. 1; 37(1):127-36).
Treatment success is indicated (i) by a decrease of the score, preferably (ii) by a decrease to below the cut-off value.
A common questionnaire that assesses sleep-related breathing disorders is the Berlin Questionnaire (A. Shahid et al., loc. cit.). An appropriate recall period can also be chosen.
Treatment success is indicated by a decrease of the score.
A common questionnaire that assesses sleep-related movement disorders is the International Restless Legs Syndrome Study Group Rating Scale. The 10-item questionnaire asks respondents to use Likert-type ratings to indicate how acutely the disorder has affected them over the course of the past week. Questions can be divided into one of two categories: disorder symptoms (nature, intensity, and frequency) and their impact (sleep issues, disturbances in daily functioning, and resultant changes in mood. Each of the ten questions requires respondents to rate their experiences with RLS on a scale from 0 to 4, with 4 representing the most severe and frequent symptoms and 0 representing the least. Total scores can range from 0 to 40. As a brief scale with excellent psychometric qualities, the instrument may be suitable for a variety of research and clinical purposes, including screening and assessment of treatment out-comes. (A. Shahid et al., loc. cit.).
Treatment response can be assessed by a decrease of the score.
Treatment response can be evaluated by above-mentioned quantitative measurements such as polysomnography or actigraphy and/or the use of the above-mentioned questionnaires. Depending on the respective sleep scale, a significant reduction or increment, respectively, in total score, or significant reduction of prevalence, frequency and impact on daily-functioning, respectively is indicative for treatment-induced improvement of the sleep disturbance.
The severity of anxiety can be assessed by using the 14-item Hamilton Anxiety Rating Scale (HAM-A), in which the assessment of sleep disturbances is integral part of the scale. Item 4 is ‘Insomnia’, defined as ‘Difficulty in falling asleep, broken sleep, unsatisfying sleep and fatigue on waking, dreams, nightmares, night terrors.’ Each item is scored on a scale of 0 (not present) to 4 (severe).
To enhance the understanding of the pathophysiology and potential compensatory mechanisms at play, resting-state fMRI has been widely applied in patients with sleep disturbances.
Altered resting state networks can be found in insomnia, hypersomnia, circadian rhythm disorders, parasomnias, sleep-related breathing disorders and sleep-related movement disorders.
In insomnia patients, dysfunctional connectivity is observed within the default mode network (DMN) and within the salience network, which is implicated in the detection and integration of emotional and sensory stimuli. Studies have suggested that these networks contain critical regions integrating emotional and bodily states, and the dysfunctional connectivity within and/or between these networks and other brain areas may underlie the vigilance, subjective distress, and poor sleep continuity of patients.
For instance, sleep deprivation in healthy subjects leads to functional connectivity alterations within and/or between the default mode network, dorsal attention network and salience network and these brain functional connectivity changes somewhat resemble the vulnerability patterns of patients with Alzheimer's disease.
In hypersomnia patients, the default mode network is affected. For instance, in idiopathic hypersomnia, distinct DMN hubs—the precuneus and medial prefrontal cortex-demonstrate significant changes, and functional connectivity in the DMN correlates with self-reported sleepiness severity.
A study investigating differences between night shift nurses and day work nurses revealed that dysrhythmia of circadian rhythms contributes to resting-state functional changes in the cerebellum, involved in sleep regulation, and cognitive functions such as responsiveness and alertness. Moreover, the functional connectivity of the DMN is fundamentally different in early and late circadian phenotypes. Like other forms of sleep disturbance, circadian rhythm disorders can lead to changes in brain functional connectivity. Changes in resting state brain functional connectivity have been reported in various diseases with circadian rhythm disorders.
While functional brain imaging is technically difficult to perform during a parasomnia event, differences in the precuneus have been observed in disorders of arousal representing a non-REM parasomnia.
The precuneus is involved in the analysis and integration of visual, audio, and somesthetic information and the monitoring of movements. The precuneus is a subregion of the DMN. Thus, in patients with parasomnias the default mode network is affected.
Resting-state fMRI studies in patients suffering from sleep-related breathing disorders, such as central sleep apnoea, indicate significant global and regional connectivity deficits, especially in the default mode network (DMN) and regions involved in the arousal and sensorimotor systems. Sleep-related movement disorders, such as for example periodic limb movements during sleep are reflected by alterations in the prefrontal motor control pathway, a subregion of the default mode network. Also, activity in the cerebellum and thalamus, with additional activation in the red nuclei and brainstem can be observed.
In many instances, resting state networks involved in sleep regulation are also involved in cognition. Thus, according to the invention, influencing those networks by a therapy according to the invention will lead to an improvement of the sleep disturbance and, if the patient treated suffers from anxiety, also of the anxiety.
Clinical data from studies of patients suffering from Treatment Resistant Depression (TRD) or Postpartum Depression (PPD) confirm that sleep disturbance can successfully be treated by the administration of 5-MeO-DMT.
In the TRD studies, which are described in more detail in the example section below, among others the MADRS item “reduced sleep”, which reflects insomnia, was assessed.
The MADRS item “reduced sleep” represents the experience of reduced duration or depth of sleep compared to the subject's own normal pattern when well. A score of 0 is assigned when the subject sleeps as usual. A score of 2 reflects slight difficulty dropping off to sleep or slightly reduced, light or fitful sleep. A score of 4 means that sleep is reduced or broken by at least two hours. A score of 6 means less than two or three hours sleep.
In the study group receiving the individualized dosing regimen, the aggregated score for the MADRS item “reduced sleep” across all 8 patients was 25 at base line. At day 1 after treatment, the earliest timepoint for assessing an impact of the treatment on sleep, it was reduced to 12 which corresponds to an improvement of 13 points or 52%. At day 7 after treatment, it was reduced to 9 which corresponds to an improvement of 16 points or 64%.
In the 12 mg group, the aggregated score for the MADRS item “reduced sleep” across all 4 patients was 12 at base line. At day 1 after treatment, it was reduced to 10 which corresponds to an improvement of 2 points or 17%. At day 7 after treatment, it was reduced to 6 which corresponds to an improvement of 6 points or 50%.
Thus, the score of the scale item that is of particular relevance to sleep disturbance, “reduced sleep”, is markedly improved. The inventors conclude that 5-MeO-DMT can be used to treat sleep disturbance, in particular patients suffering from a mental disorder or a nervous system disorder.
Treating a patient suffering from sleep disturbance, in particular insomnia, and associated anxiety with 5-MeO-DMT or a pharmaceutically acceptable salt thereof reduces or eliminates the anxiety and leads to an improvement of the sleep disturbance, in particular the insomnia.
The reduction or elimination of anxiety in a patient suffering from sleep disturbance, in particular insomnia, is observed about 2 hours after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof; on day 1, for instance after about 24 hours; on day 7; on day 14; and/or on day 28 after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof.
The reduction or elimination of anxiety in a patient suffering from sleep disturbance, in particular insomnia, occurs not later than about 2 hours after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof. The reduction or elimination of anxiety preferably persists until at least 6 days; in particular until at least 14 days; more preferably until at least 28 days after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof.
As indicated above, anxiety is an important aspect in patients suffering from sleep disturbance. An improvement in anxiety will therefore also lead to an improvement of the sleep disturbance. Since anxiety furthermore also affects other aspects of the sleep disturbance, the inventors conclude that the observed improvement in anxiety will additionally contribute to an overall improvement of the sleep disturbance, in particular insomnia.
In cases of idiopathic sleep disturbance, a clinical response may be reflected by a reduction in the Clinical Global Impression-Severity (CGI-S) score. According to the invention, a reduction in the CGI-S score means that the CGI-S is reduced by at least 1. Preferably, the CGI-S is reduced by at least 2 and/or to a score of 0. It is especially preferred if the CGI-S is reduced by at least 3 and/or to a score of 0.
An improvement of idiopathic sleep disturbance, as reflected by a reduction in the CGIS score, is observed on day 1, for instance after about 24 hours; on day 7; on day 14; and/or on day 28 after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof.
An improvement of idiopathic sleep disturbance, as reflected by a reduction in the CGIS score, occurs not later than about 24 hours after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof.
An improvement in idiopathic sleep disturbance, as reflected by a reduction in the CGIS score, preferably persists until at least 6 days; in particular until at least 14 days; more preferably until at least 28 days after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof.
In cases of idiopathic sleep disturbance, an improvement in sleep disturbance, as reflected by at least a score of “much improved” in the Clinical Global Impression-Improvement (CGI-I) score or the Patient Global Impression-Improvement (PGI-I) score, preferably occurs not later than about 24 hours after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof.
In cases of idiopathic sleep disturbance, an improvement in sleep disturbance, as reflected by a reduction by at least a score of “much improved” in the CGI-I score or the PGI-I score, preferably persists until at least 6 days; in particular until at least 14 days; more preferably until at least 28 days after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof.
Improvements sleep disturbance may also be assessed by any other scale reflecting changes in sleep quality or quantity, as indicated above, for instance the Pittsburgh Sleep Quality Index (PSQI).
If treatment outcome is assessed using the PSQI, treatment success is indicated (i) by a decrease of the score, preferably (ii) by a decrease to 5 or below.
An improvement in sleep disturbance, as reflected by a decrease of the PSQI score, in particular by a decrease to 5 or below, preferably occurs not later than about 24 hours after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof, wherein the recall period does not start earlier than the time point when acute psychedelic experiences have subsided after the last administration to the assessment time point.
The improvement in sleep disturbance, as reflected by a decrease of the PSQI score, preferably persists until at least 6 days; in particular until at least 14 days; more preferably until at least 28 days after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof, wherein the recall period does not start earlier than the time point when acute psychedelic experiences have subsided after the last administration to the assessment time point.
An improvement of sleep disturbance, as reflected by a reduction in the PSQI score, is observed on day 1, for instance after about 24 hours; on day 7; on day 14; and/or on day 28 after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof, wherein the recall period does not start earlier than the time point when acute psychedelic experiences have subsided after the last administration to the assessment time point.
Anxiety and sleep disturbance, in particular insomnia, are closely linked to mental and nervous system disorders. Both, anxiety and sleep disturbance, in particular insomnia, occur in mental or nervous system disorders, such as disorders characterized by depressive episodes, for example, Major Depressive Disorder (MDD), Postpartum Depression (PPD), Persistent Depressive Disorder, Seasonal Affective Disorder and Bipolar Disorder (BD), such as Bipolar I Disorder and Bipolar II Disorder; Anxiety Disorder, for example Separation Anxiety Disorder, Agoraphobia, Generalised Anxiety Disorder (GAD), Social Anxiety Disorder (SAD), Panic Disorder, and Phobias, and Substance/Medication Induced Anxiety Disorder; Somatic Symptom Disorder; Obsessive Compulsive and Related Disorders, for example, Obsessive Compulsive Disorder (OCD) and Body Dysmorphic Disorder (BDD); Somatoform Disorders, for example, Body Dysmorphic Disorder (BDD); Obsessive Compulsive Dis-order (OCD); Post-Traumatic Stress Disorder (PTSD); Pain Disorders, for example Chronic Pain, and Fibromyalgia and Migraine; Mental and Behavioural Disorders due to Psychoactive Substance Use, for example, Substance Use Disorder (SUD); Psychotic Disorders, for example Schizophrenia; Parkinson's Disease; or Schizotypal Personality Disorder; Dementia, for example Alzheimer's Dementia (AD), Parkinson's Disease Dementia (PDD), Dementia with Lewy Bodies, Vascular Dementia, Fronto-Temporal Dementias; Parkinson's Disease (PD); Eating Disorders; Attention Deficit Hyperactivity Disorder (ADHD); Personality Disorders, for example Schizotypal Personality Disorder and Borderline Personality Disorder; Autism Spectrum Disorder; Chronic Fatigue Syndrome.
Anxiety and sleep disturbance, in particular insomnia, also both occur in medical health conditions leading to an associated mental or nervous system condition, such as HIV, Traumatic Brain Injury or Post COVID Condition.
A treatment according to the invention will lead to improvements in both anxiety and sleep disturbance, in particular insomnia, and furthermore to an improvement in the associated mental or nervous system disorder, examples of which are listed above, and also to an improvement in the mental or nervous system condition associated with certain medical health conditions as explained above.
There are several disorders which are characterized by depressive episodes.
A depressive episode is a period of depressed mood and/or loss of pleasure in most activities.
For instance, according to DSM-V, a Major Depressive Episode is characterized by five or more symptoms that have been present during the same 2-week period and represent a change from previous functioning; at least one of the symptoms being either (1) depressed mood or (2) loss of interest or pleasure.
A patient suffering from a Disorder Characterized by Depressive Episodes may suffer from a treatment resistant form of the disorder.
A patient suffering from a Disorder Characterized by Depressive Episodes may in addition show symptoms of anxiety, without being diagnosed as suffering from an anxiety disorder (subthreshold anxiety).
Subthreshold anxiety as the term is used herein in particular means that the patient has a Hamilton Rating Scale for Anxiety (HAM-A) score of at least 9 but of less than 18 and/or a Beck Anxiety Inventory (BAI) score of at least 11 but of less than 16.
A patient may also have been diagnosed with a Disorder Characterized by Depressive Episodes and in addition with an anxiety disorder, i.e., be considered having a comorbidity of the Disorder and anxiety. Such a patient may have an HAM-A score of at least 18 and/or a BAI score of at least 16.
Anxiety symptoms in a patient suffering from a Disorder Characterized by Depressive Episodes, such as a patient suffering from the Disorder and subthreshold anxiety or a patient having a comorbidity of the Disorder and anxiety, are linked to more severe depression and to an increased incidence of suicidal ideation.
Anxiety in a patient suffering from a Disorder Characterized by Depressive Episodes may be assessed by using the Hamilton Rating Scale for Anxiety (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Beck Anxiety Inventory (BAI); the Anxiety/Somatization factor of the Hamilton Rating Scale for Depression (HAM-D) (sum of items: anxiety (psychic), anxiety (somatic), somatic symptoms (gastrointestinal), somatic symptoms (general), hypochondriasis, and insight); the HAM-D items “anxiety psychic” and/or “anxiety somatic”; the Montgomery-Åsberg Depression Rating Scale (MADRS) item “inner tension”; the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Suicidal ideation may be assessed using the MADRS item “suicidal thoughts” or using the Columbia Suicide Severity Rating Scale (C-SSRS).
In patients suffering from a Disorder Characterized by Depressive Episodes altered functional connectivity is observed within and/or between several brain regions implicated in processing, regulation, emotional memory; cognitive processes related to rumination; impaired concentration and physiological arousal. Anxiety also involves aberrant connectivity within and/or between resting state networks, such as the default mode network and the salience network. The aberrant connectivity can be normalized by a treatment according to the invention.
Treating a patient suffering from a Disorder Characterized by Depressive Episodes, including a treatment resistant form of the Disorder, and having anxiety symptoms, such as a patient suffering from the Disorder and subthreshold anxiety or a patient having a comorbidity of the Disorder and anxiety, with 5-MeO-DMT or a pharmaceutically acceptable salt thereof reduces or eliminates the anxiety and leads to an improvement of the Disorder.
The reduction or elimination of anxiety in a patient suffering from a Disorder Characterized by Depressive Episodes, including a treatment resistant form of the Disorder, such as a patient suffering from the Disorder and subthreshold anxiety or a patient having a comorbidity of the Disorder and anxiety, is observed about 2 hours after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof; on day 1, for instance after about 24 hours; on day 7; on day 14; and/or on day 28 after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof.

Major Depressive Disorder (MDD) is a mood disorder that causes a persistent feeling of sadness and loss of interest. It affects how a person feels, thinks, and behaves and can lead to a variety of emotional and physical problems.
A patient suffering from MDD may suffer from a treatment resistant form of the disorder.
A patient suffering from MDD may in addition show symptoms of anxiety, without being diagnosed as suffering from an anxiety disorder (subthreshold anxiety). As the term is used herein, such a patient suffers from anxious depression.
Subthreshold anxiety as the term is used herein in particular means that the patient has a Hamilton Rating Scale for Anxiety (HAM-A) score of at least 9 but of less than 18 and/or a Beck Anxiety Inventory (BAI) score of at least 11 but of less than 16.
A patient may also have been diagnosed with MDD and in addition with an anxiety disorder, i.e., be considered having a comorbidity of anxiety and depression (rather than anxious depression). Such a patient may have an HAM-A score of at least 18 and/or a BAI score of at least 16.
Anxiety symptoms in a patient suffering from MDD, such as a patient suffering from anxious depression or a patient having a comorbidity of anxiety and depression, are linked to more severe depression and to an increased incidence of suicidal ideation.
Anxiety in a patient suffering from MDD may be assessed by using the Hamilton Rating Scale for Anxiety (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Beck Anxiety Inventory (BAI); the Anxiety/Somatization factor of the Hamilton Rating Scale for Depression (HAM-D) (sum of items: anxiety (psychic), anxiety (somatic), somatic symptoms (gastrointestinal), somatic symptoms (general), hypochondriasis, and insight); the HAM-D items “anxiety psychic” and/or “anxiety somatic”; the Montgomery-Åsberg Depression Rating Scale (MADRS) item “inner tension”; the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Suicidal ideation may be assessed using the MADRS item “suicidal thoughts” or using the Columbia Suicide Severity Rating Scale (C-SSRS).
In patients suffering from MDD dysfunctional connectivity and regulation within and/or between multiple resting-state networks including the DMN, salience network, executive control network and limbic network is observed. Functional connectivity differs significantly from that observed in healthy controls. Anxiety also involves aberrant connectivity within and/or between resting state networks, such as the default mode network and the salience network. The aberrant connectivity can be normalized by a treatment according to the invention.

Postpartum Depression (PPD) is a debilitating mood disorder occurring during pregnancy or within 4 weeks following delivery. While over 50% of women may experience short-lasting low mood or tearfulness after childbirth, a subset of women may develop PPD. Epidemiological studies estimate that the prevalence rate of PPD is about 15%.
A patient may suffer from moderate or severe PPD as indicated by a Montgomery-Åsberg Depression Rating Scale (MADRS) score of 20 or more or by a Hamilton Depression Rating Scale (HAM-D) score of 16 or more. It is further considered that the patient may suffer from severe PPD as indicated by a Montgomery-Åsberg Depression Rating Scale (MADRS) score of 35 or more or by a Hamilton Depression Rating Scale (HAM-D) score of 27 or more.
A patient treated according to the invention may have a Montgomery-Åsberg Depression Rating Scale (MADRS) score of 20 or more or a 17-item Hamilton Depression Rating Scale (HAM-D) score of 16 or more.
Further, a patient treated according to the invention may have a MADRS score of 28 or more or a HAM-D score of 22 or more.
Still further, a patient treated according to the invention may have a MADRS score of 35 or more or a HAM-D score of 25 or more.
The patient suffering from PPD may suffer from a treatment resistant form of the disorder.
Anxiety symptoms are a significant feature of PPD. They are significantly more common in women who experience postpartum depression than in women with non-postpartum depression.
It is thought that the added burden of anxiety symptoms may be due to the responsibility of looking after a new child and significant sleep deprivation.
Depression and anxiety during the postpartum period both not only affects the mothers' overall wellbeing, but it also affects how a mother interacts with her child and thus how the child develops.
PPD can be assessed by the Edinburgh Postnatal Depression Scale (EPDS), a scale evaluating how the mother has felt the past 7 days. Anxiety is evaluated in three out of 10 questions that are assessed by the questionnaire. Rating ranges from “0” “No, not at all” to “3” “Yes, most of the time”. With a threshold level of a total score of 13, anxiety can be considered as a fundamental part of PPD diagnosis.
In patients with PPD, significant changes in neural activity in brain regions important for self-regulation, empathy, emotion, and cognition are observed. PPD is associated with dysfunctional connectivity of resting state networks, for instance, within and/or between the default mode network and frontoparietal network.
Anxiety also involves aberrant connectivity within and/or between resting state networks, such as the default mode network and the salience network. The aberrant connectivity can be normalized by a treatment according to the invention.

Anxiety moreover compromises maternal functioning.
Maternal functioning can, for instance, be assessed using the Barkin Index of Maternal Functioning (BIMF). This index was designed to measure functioning in the year after childbirth. The BIMF is a 20-item self-report measure of functioning. Each item is assigned a score between 0 and 6 so that the maximum total score is 120. The higher the score, the better maternal functioning is rated.
The BIMF identifies the key functional domains of a mother during the postnatal period as: self-care, infant care, mother-child interaction, psychological wellbeing of the mother, social support, management, and adjustment.
A BIMF score of 95 or below is considered herein as representing slightly compromised maternal functioning, a score of 80 or below is considered herein as representing compromised maternal functioning, a score of 65 or below is considered herein as representing severely compromised maternal functioning.
The inventors have determined that increases in the score of the BPRS item “anxiety” and/or the MADRS item “inner tension” have negative impacts on maternal functioning (maternal competence relating to interactions with the infant(s) as well as maternal self-care).
In particular, the inventors have determined that increases in the score of the BPRS item “anxiety” have negative impacts on both aspects of maternal functioning (maternal competence relating to interactions with the infant(s) as well as maternal self-care). Increased scores in the BPRS item “anxiety” impair psychological wellbeing, social support and management.
Conversely, improvements regarding this BPRS item lead to improvements in maternal functioning, in particular in the BIMF functional domains psychological wellbeing, social support and/or management.
Moreover, the inventors have determined that increases in the score of the MADRS item “inner tension” have negative impacts on both aspects of maternal functioning (maternal competence relating to interactions with the infant(s) as well as maternal self-care). Increased scores in the MADRS item “inner tension” impair mother-child interaction as well as psychological well-being of the mother as assessed by the BIMF.
Conversely, improvements regarding this MADRS item lead to improvements in maternal functioning, in particular in the BIMF functional domains mother-child interaction and/or psychological well-being of the mother.
The inventors conclude that 5-MeO-DMT can be used to treat PPD patients to achieve an improvement of anxiety.
The inventors furthermore conclude that a reduction or elimination of anxiety by treating a PPD patient does not only lead to a reduction in the MADRS total score, but also to an improvement in maternal functioning, as reflected by an increase in the BIMF score.
The BIMF total score is improved by 10% or more, preferably by 20% or more.
The improvement of maternal functioning in a patient suffering from PPD is reflected by at least an improvement in the BIMF total score on day 7; on day 14; and/or on day 28 after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof.
The improvement of maternal functioning in a patient suffering from PPD, as reflected by an improvement in the BIMF total score, occurs not later than about 6 days after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof. The improvement of maternal functioning, as reflected by an improvement in the BIMF total score, preferably persists until at least 14 days; more preferably until at least 28 days after the last administration of 5-MeO-DMT or a pharmaceutically acceptable salt thereof.
Persistent Depressive Disorder, also referred to as dysthymia, is a chronic form of depression. It is diagnosed if depression is present for most of the day for the majority of days over at least a two year period. Any symptom-free period is less than 2 months.
While depressed, two or more of the following must be present: 1. Hopelessness; 2. Energy low or fatigue; 3. Self-esteem is low; 4. Sleep decreased (insomnia) or increased (hypersomnia): 5. Appetite poor, or overeating; 6. Difficulty making decisions or poor concentration.
The patient suffering from Persistent Depressive Disorder may suffer from a treatment resistant form of the disorder.
A patient suffering from Persistent Depressive Disorder may in addition show symptoms of anxiety, without being diagnosed as suffering from an anxiety disorder (subthreshold anxiety).
Subthreshold anxiety as the term is used herein in particular means that the patient has a Hamilton Rating Scale for Anxiety (HAM-A) score of at least 9 but of less than 18 and/or a Beck Anxiety Inventory (BAI) score of at least 11 but of less than 16.
A patient may also have been diagnosed with Persistent Depressive Disorder and in addition with an anxiety disorder, i.e., be considered having a comorbidity of the Disorder and anxiety. Such a patient may have an HAM-A score of at least 18 and/or a BAI score of at least 16.
Anxiety symptoms in a patient suffering from Persistent Depressive Disorder, such as a patient suffering from the Disorder and subthreshold anxiety or a patient having a comorbidity of the Disorder and anxiety, are linked to more severe depression and to an increased incidence of suicidal ideation.
Anxiety in a patient suffering from Persistent Depressive Disorder may be assessed by using the Hamilton Rating Scale for Anxiety (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Beck Anxiety Inventory (BAI); the Anxiety/Somatization factor of the Hamilton Rating Scale for Depression (HAM-D) (sum of items: anxiety (psychic), anxiety (somatic), somatic symptoms (gastrointestinal), somatic symptoms (general), hypochondriasis, and insight); the HAM-D items “anxiety psychic” and/or “anxiety somatic”; the Montgomery-Åsberg Depression Rating Scale (MADRS) item “inner tension”; the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Suicidal ideation may be assessed using the MADRS item “suicidal thoughts” or using the Columbia Suicide Severity Rating Scale (C-SSRS).
In patients suffering from Persistent Depressive Disorder altered functional connectivity is observed within and/or between several brain regions implicated in processing, regulation, emotional memory; cognitive processes related to rumination; impaired concentration and physiological arousal. Dysfunctional connectivity is observed within and/or between the DMN, salience network, executive control network and limbic network. Functional connectivity differs significantly from that observed in healthy controls.
Anxiety also involves aberrant connectivity within and/or between resting state networks, such as the default mode network and the salience network. The aberrant connectivity can be normalized by a treatment according to the invention.

Seasonal Affective Disorder is a mood disorder with seasonal pattern, with symptoms often beginning in autumn and remitting in spring. Many people experience sadness, hopelessness, a loss of interest in activities, fatigue, and social withdrawal.
The patient suffering from Seasonal Affective Disorder may suffer from a treatment resistant form of the disorder.
A patient suffering from Seasonal Affective Disorder may in addition show symptoms of anxiety, without being diagnosed as suffering from an anxiety disorder (subthreshold anxiety).
Subthreshold anxiety as the term is used herein in particular means that the patient has a Hamilton Rating Scale for Anxiety (HAM-A) score of at least 9 but of less than 18 and/or a Beck Anxiety Inventory (BAI) score of at least 11 but of less than 16.
A patient may also have been diagnosed with Seasonal Affective Disorder and in addition with an anxiety disorder, i.e., be considered having a comorbidity of the Disorder and anxiety. Such a patient may have an HAM-A score of at least 18 and/or a BAI score of at least 16.
Anxiety symptoms in a patient suffering from Seasonal Affective Disorder, such as a patient suffering from the Disorder and subthreshold anxiety or a patient having a comorbidity of the Disorder and anxiety, are linked to more severe depression and to an increased incidence of suicidal ideation.
Anxiety in a patient suffering from Seasonal Affective Disorder may be assessed by using the Hamilton Rating Scale for Anxiety (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Beck Anxiety Inventory (BAI); the Anxiety/Somatization factor of the Hamilton Rating Scale for Depression (HAM-D) (sum of items: anxiety (psychic), anxiety (somatic), somatic symptoms (gastrointestinal), somatic symptoms (general), hypochondriasis, and insight); the HAM-D items “anxiety psychic” and/or “anxiety somatic”; the Montgomery-Åsberg Depression Rating Scale (MADRS) item “inner tension”; the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Suicidal ideation may be assessed using the MADRS item “suicidal thoughts” or using the Columbia Suicide Severity Rating Scale (C-SSRS).
Resting state activity involved in sensorimotor, attention, and visual processing is altered in patients with Seasonal Affective Disorder compared to healthy controls.

Bipolar Disorder is a mental health condition characterized by extreme mood swings that include emotional lows (major depressive episodes) and highs (manic or hypomanic episodes). Bipolar disorder is a recurrent chronic disorder that affects more than 1% of the world's population irrespective of ethnic origin or socioeconomic status.
BD is classified as Bipolar I Disorder if there has been at least one manic episode, with or without depressive episodes. It is classified as Bipolar II Disorder if there has been at least one hypomanic episode (but no full manic episodes) and one major depressive episode. If these symptoms are due to drugs or medical problems, they are not diagnosed as bipolar disorder.
The patient suffering from BD including Bipolar I Disorder and Bipolar II Disorder may suffer from a treatment resistant form of the disorder.
The patient suffering from BD, whether diagnosed with Bipolar II Disorder or with Bipolar I Disorder, in particular suffers from a current major depressive episode.
The severity of a current major depressive episode may be assessed using the Montgomery-Åsberg Depression Rating Scale (MADRS). The patient may have a total score of equal to or greater than 19, such as greater or equal than 24, in particular greater or equal than 37.
Alternatively or in addition, the patient may have a Bipolar Depression Rating Scale (BDRS) total score of 19, such as greater or equal than 24, in particular greater or equal than 37.
Anxiety symptoms are common in BD and a co-morbid diagnosis of any anxiety disorder is higher for patients with BD than major depressive disorder.
Anxiety is moreover a commonly reported feature of certain manic episodes, which can subsequently be labelled as a ‘mixed presentation’.
A patient suffering from BD may in addition show symptoms of anxiety, without being diagnosed as suffering from an anxiety disorder (subthreshold anxiety).
Subthreshold anxiety as the term is used herein in particular means that the patient has a Hamilton Rating Scale for Anxiety (HAM-A) score of at least 9 but of less than 18 and/or a Beck Anxiety Inventory (BAI) score of at least 11 but of less than 16.
A patient may also have been diagnosed with BD and in addition with an anxiety disorder, i.e., be considered having a comorbidity of BD and anxiety. Such a patient may have an HAM-A score of at least 18 and/or a BAI score of at least 16.
The presence of co-morbid anxiety symptoms is important to identify as co-morbid anxiety disorders increase the risk of suicide in patients with bipolar disorder.
Anxiety in a patient suffering from BD may be assessed by using the Hamilton Rating Scale for Anxiety (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Beck Anxiety Inventory (BAI); the Anxiety/Somatization factor of the Hamilton Rating Scale for Depression (HAM-D) (sum of items: anxiety (psychic), anxiety (somatic), somatic symptoms (gastrointestinal), somatic symptoms (general), hypochondriasis, and insight); the HAM-D items “anxiety psychic” and/or “anxiety somatic”; the Montgomery-Åsberg Depression Rating Scale (MADRS) item “inner tension”; the Bipolar Depression Rating Scale (BDRS) item “anxiety”; the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Suicidal ideation may be assessed using the MADRS item “suicidal thoughts”; the BDRS item “suicidal ideation” or using the Columbia Suicide Severity Rating Scale (C-SSRS).
Patients suffering from Bipolar Disorder show characteristic aberrant intrinsic organization and interconnectivity of resting state networks. In comparison with healthy controls, resting state functional magnetic resonance imaging studies demonstrated functional connectivity alterations of specific regions within and/or between the default mode network, the salience network, and the central executive network.
Anxiety also involves aberrant connectivity within and/or between resting state networks, such as the default mode network and the salience network. The aberrant connectivity can be normalized by a treatment according to the invention.

An Anxiety Disorder is a type of mental health condition. Symptoms include feelings of nervousness, panic and fear as well as sweating and a rapid heartbeat. Anxiety involves a complex cognitive, affective, physiological, and behavioural response system associated with preparation for anticipated events or circumstances perceived as threatening.
The patient suffering from an Anxiety Disorder may suffer from a treatment resistant form of the disorder.
The severity of an Anxiety Disorder can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Anxiety Disorders are moreover associated with suicidal ideation.
Suicidal ideation may be assessed using the Columbia Suicide Severity Rating Scale (C-SSRS).
Anxiety disorders are studied by functional magnetic resonance imaging. In general, all anxiety disorders show abnormalities in the default mode network (DMN). Further networks affected by these disorders are the salience network (SN) and the sensorimotor network (SMN). The resting state balance within and/or between each of these networks, e.g., SMN and SN, relative to the DMN may be abnormal in the different anxiety disorders.

A Phobia is an anxiety disorder defined by a persistent and excessive fear of an object or situation. A patient suffering from phobia experiences extreme anxiety when anticipating exposure or being exposed to a feared stimulus. There are animal type (spiders, snakes, dogs) phobias, natural environment type (tornadoes, heights, water, fire) phobias, blood injection type (needles, medical procedures) phobias, situational type (flying on an airplane, enclosed spaces) phobias and other type phobias (phobias that do not fit into one the previous categories).
Phobias typically result in a rapid onset of fear and are usually present for more than six months. Patients make great efforts to avoid the feared stimulus. Fear and avoidance cause significant distress and/or impairment in occupational, academic, or social functioning.
The patient suffering from Phobia may suffer from a treatment resistant form of the disorder.
The severity of Phobia can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Phobia is moreover associated with suicidal ideation.
Suicidal ideation may be assessed using the Columbia Suicide Severity Rating Scale (C-SSRS).
In individuals with specific Phobia, the amygdala, the anterior cingulate cortex (ACC) and insular cortex all appear to be hyperresponsive to phobia-related stimuli. For instance, functional neuroimaging studies identified the dorsal part of the anterior cingulate cortex (dACC), which is part of the salience network, to be hyperresponsive to phobia-related stimuli or the anticipation of such stimuli.

Substance/Medication-Induced Anxiety Disorder is an anxiety disorder in which anxiety or panic occurs after using alcohol, a drug of abuse, or a medication or after a toxin exposure. Substance/Medication-Induced Anxiety Disorder leads to prominent symptoms of panic or anxiety and can occur during the intoxication or withdrawal phases of using a substance or medication.
The disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning.
While taking substances or medication or within a short time thereafter, individuals suffering from Substance/Medication-Induced Anxiety Disorder may feel nervous and worried, experience symptoms of negative thinking, may have trouble concentrating or remembering things, may have fear of losing control or insanity or death, may lose weight due to gastrointestinal problems, may have chills, hot flashes, sweating, shaking, numbness, or a pounding heartbeat, trouble breathing, trouble swallowing, or chest pain.

Somatic Symptom Disorder is a mental disorder diagnosed when a person has a significant focus on physical symptoms, such as pain, weakness, or shortness of breath to a level that results in major distress and/or problems functioning and/or cause disruption in daily life. Feelings and behaviours related to the illness are excessive or out of proportion.
Health-related quality of life is often impaired, both physically and mentally. In severe Somatic Symptom Disorder, the impairment is marked, and when persistent, the disorder can lead to invalidism.
Somatic symptom disorder can be assessed by the DSM-5 Level 2—Somatic Symptom—Adult measure. This measure comprises 15 somatic symptoms. Respondents are asked to rate the severity of the individual's somatic symptoms during the past 7 days. The total score can range from 0 to 30, with higher scores indicating greater severity of somatic symptoms. A cut-off value of 5, 10 and 15 indicates low, medium, high somatic symptom severity, respectively.
Moreover, anxiety in individuals suffering from Somatic Symptom Disorder can be assessed using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Patients suffering from Somatic Symptom Disorder and anxiety symptoms moreover tend to also suffer from suicidal ideation.
Suicidal ideation may be assessed using the Columbia Suicide Severity Rating Scale (C-SSRS).
Brain functional connectivity analysis reveals alterations within and/or between resting state networks in patients with Somatic Symptom Disorder in comparison to healthy controls. Alterations are identified within and/or between default mode network (DMN), salience network, dorsal attention network (DAN) and sensorimotor network. Somatic Symptom Disorder may be associated with alterations of sensory-discriminative processing of somatic symptoms, which is influenced by affective processing.
Anxiety also involves aberrant connectivity within and/or between networks. The aberrant connectivity can be normalized by a treatment according to the invention.

Obsessive Compulsive Disorder (OCD) is a mental illness that causes repeated unwanted thoughts or sensations (obsessions) or the urge to do something over and over again (compulsions). Patients may suffer from both obsessions and compulsions.
The patient suffering from OCD may suffer from a treatment resistant form of the disorder.
Anxiety and OCD are very closely linked. Worries and obsessions may share a common underlying process of intolerance of uncertainty in anxiety and OCD.
The severity of anxiety in patients suffering from OCD can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.

Patients suffering from Body Dysmorphic Disorder (BDD) misperceive defects in their appearance, disrupting their ability to function in their daily lives, with disturbing preoccupations, ritualistic behaviours, and emotional distress.
The patient suffering from BDD may suffer from a treatment resistant form of the disorder.
The presence of body dysmorphic disorder (BDD) is found to be a significant predictor of anxiety, and comorbid anxiety disorders are highly prevalent amongst patients with body dysmorphic disorder.
Anxiety may have a stronger detrimental impact on patients with BDD than on healthy controls. A path analysis study found that anxiety is more strongly associated with adverse outcomes such as depression, suicidality and impairment in patients with BDD when compared to this relationship in healthy controls.
The severity of anxiety in patients suffering from BDD can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.

Post-Traumatic Stress Disorder (PTSD) is a mental health condition that can develop based on a terrifying event-either experienced or witnessed by the patient. Symptoms may include flashbacks, nightmares and severe anxiety, as well as uncontrollable thoughts about the event.
A patient suffering from PTSD may suffer from a treatment resistant form of the disorder.
Post-traumatic stress disorder (PTSD) is characterised by abnormal cognitive and emotional processes that interfere with daily life following a traumatic event.
Anxiety-related symptoms, which are thought to characterise Post-Traumatic Stress Disorder (PTSD), may be due to a failure of extinguishing conditioned fear responses.
Co-morbid anxiety disorders are highly prevalent in patients with PTSD. The presence of PTSD increases the risk of concomitant anxiety disorder.
The severity of anxiety in patients suffering from PTSD can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Patients suffering from PTSD and anxiety symptoms moreover tend to also suffer from suicidal ideation.

Chronic Pain, also referred to as persistent pain, is long standing pain that persists beyond the usual recovery period, for instance, after an injury or operation, despite medication or treatment. Patients may also suffer from Chronic Pain without any apparent cause, such as a history of an injury or operation.
A patient suffering from Chronic Pain may suffer from a treatment resistant form of the disorder.
The prevalence of anxiety disorders is markedly elevated in patients with Chronic Pain compared to in those without that condition.
Anxiety can have a detrimental effect on the perception of pain. Pain-related anxiety may worsen the chronic pain experience by reducing the perceived ability to control pain, and has been shown to correlate with reduced use of cognitive pain controlling strategies.
The relationship between anxiety and increased pain intensity may be mediated by the presence of sleep disturbance.
The severity of anxiety in patients suffering from Chronic Pain can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Patients suffering from Chronic Pain and anxiety symptoms moreover tend to also suffer from suicidal ideation.
Suicidal ideation may be assessed using the Columbia Suicide Severity Rating Scale (C-SSRS).
Chronic Pain patients display brain alterations regarding brain function and structure. These changes are related to the persistence of pain, long after the initial nociceptive input has disappeared. Resting state functional magnetic resonance imaging reveals alterations in distinct regions within and/or between the default mode network, the sensorimotor network, and the salience network.
Anxiety also involves aberrant connectivity within and/or between resting state networks, such as the default mode network, the salience network and the sensorimotor network. The aberrant connectivity can be normalized by a treatment according to the invention.

Fibromyalgia is a chronic disorder that is characterized by widespread musculoskeletal pain throughout the body or at multiple sites, accompanied by fatigue, sleep disturbances, memory and mood issues. Patients may also encounter muscle and joint stiffness, tenderness to touch, numbness or tingling in the arms and legs, problems with concentrating, thinking clearly, and memory (sometimes called “fibro fog”), heightened sensitivity to light, noise, odors, and temperature, or digestive issues, such as bloating or constipation.
Symptoms of anxiety are common among patients suffering from Fibromyalgia. Anxious symptoms can further compromise the course of the disease. Anxiety in Fibromyalgia may increase the severity of pain perception and thus increase the severity of the disease.
The severity of anxiety in patients suffering from Fibromyalgia can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.

Migraine is a headache that can cause severe throbbing pain or a pulsing sensation, usually on one side of the head. Migraine is often accompanied by nausea, vomiting, and extreme sensitivity to light and sound. Migraine attacks can last for hours to days, and the pain can be so severe that it interferes with daily activities.
In some patients, a symptom known as an aura occurs before or with the headache. This symptom can include visual disturbances, such as flashes of light or blind spots, or other disturbances, such as tingling on one side of the face or in an arm or leg and difficulty speaking.
Anxiety is highly prevalent in migraine patients.
Anxiety disorders are far more prevalent among migraine patients than in the general population, especially those with chronic migraines. Migraine and anxiety disorders have a bidirectional relationship, with one increasing the risk of the other, although in most cases, it is the anxiety disorder that precedes migraine.
The presence of anxiety disorders in patients with Migraine can lead to impairment and significantly affects the patient's quality of life.
The severity of anxiety in patients suffering from Migraine can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Patients suffering from Migraine and anxiety symptoms moreover tend to also suffer from suicidal ideation.
Suicidal ideation may be assessed using the Columbia Suicide Severity Rating Scale (C-SSRS).
In patients suffering from migraine, resting state network analysis shows differences to healthy controls. Studies during the migraine attacks reveal marked abnormalities in networks relevant for mediating cognitive, attentional, somatosensory and emotional components of pain.
Current evidence for the pathogenesis of anxiety disorders involves the activation of a ‘threat circuit’ in the brain with the perception of noxious stimuli that consists of connections between the prefrontal cortex, insula, and amygdala. These structures are a part of the limbic system, and their overstimulation leads to the features of anxiety disorders. Therefore, in a patient with chronic migraine, the limbic system structures are highly sensitized due to the neuronal hyperexcitability that occurs in the regional and neighbouring areas in the brain.

Substance Use Disorder (SUD) is a mental disorder that affects a person's behaviour, leading to a person's inability to control their use of substances such as legal or illegal drugs, alcohol, or medications. Symptoms can range from moderate to severe, with addiction being the most severe form of SUD.
A patient suffering from SUD may suffer from a treatment resistant form of the disorder.
Anxiety is a symptom commonly seen in patients suffering from SUD. Significantly elevated rates of moderate-severe and severe anxiety are observed in patients with SUD.
Substance use may perpetuate anxiety symptoms by providing an avenue to temporarily avoid anxious symptoms and thereby preventing resolution or extinguishment.
The severity of anxiety in patients suffering from SUD can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Patients suffering from SUD and anxiety symptoms moreover tend to also suffer from suicidal ideation.
Suicidal ideation may be assessed using the Columbia Suicide Severity Rating Scale (C-SSRS).
Resting state functional connectivity (rsFC) is found to be altered not only in patients with anxiety, but also in patients with Substance Use Disorders. In particular, deficits in cognitive control are associated with altered connectivity within and/or between resting state networks, such as the default mode network, the salience network, the central executive network, the limbic network and the reward network.
The aberrant connectivity can be normalized by a treatment according to the invention.

Psychotic Disorders are severe mental disorders that cause abnormal thinking and perceptions. Psychotic disorders are characterised by significant impairments in reality testing and alterations in behaviour manifest in positive symptoms such as persistent delusions, persistent hallucinations, disorganised thinking (typically manifest as disorganised speech), grossly disorganised behaviour, and experiences of passivity and control, negative symptoms such as blunted or flat affect and avolition, and psychomotor disturbances.
A patient suffering from a Psychotic Disorder may suffer from a treatment resistant form of the disorder.
Anxiety disorders are highly prevalent in patients with psychotic disorders.
The severity of anxiety in patients suffering from a Psychotic Disorder can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.

Parkinson's Disease (PD) is an illness characterized by gradually progressive problems with movement, most commonly involving slowing of movements, a tremor present at rest, and walking instability which can cause falls.
Anxiety is a common psychiatric comorbidity in Parkinson's disease (PD) and contributes to significant impairments in areas of cognitive, functional, motor and social performance.
The severity of anxiety in patients suffering from PD can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.

Dementia is generally characterized by a loss of memory, language, problem-solving and other thinking abilities that are severe enough to interfere with daily life.
Dementia is caused by brain changes which trigger a decline in cognitive abilities and also affect behaviour, feelings and relationships.
Neuropsychiatric symptoms in Dementia patients include anxiety.
The severity of anxiety in patients suffering from Dementia can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Dementia affects various functional and structural connectivity networks in the brain, as can be shown by magnetic resonance imaging studies. Alterations within and/or between the default mode network (DMN), the salience network, and the central executive network (CEN) are observed.
Anxiety also involves aberrant connectivity within and/or between resting state networks, such as the default mode network and the salience network. The aberrant connectivity can be normalized by a treatment according to the invention.

Alzheimer's Dementia (AD) is a highly prevalent neurodegenerative disorder with an insidious onset and gradual progression of cognitive deficits. The percentage of neurocognitive disorders attributable to Alzheimer's disease ranges from about 60% to over 90%, depending on the setting and diagnostic criteria. Decline in learning and memory is an early and predominant feature, and the decline is progressive.
Cognitive dysfunction is primarily due to degeneration of the prefrontal cortex.
Patients with Alzheimer's dementia exhibit a characteristic mood lability, irritability, and apathy in reaction to their cognitive impairment. Dysfunction in sustained attention, visual orienting and memory impairment can interfere with normal daily functioning.
Neuropsychiatric symptoms are common in AD. Anxiety is the third most common neuropsychiatric symptom in AD after depression and apathy. In fact, there is a high prevalence of anxiety in AD patients.
Anxiety may also be a risk factor for the development of AD and may be an early manifestation of the disease.
The severity of anxiety in patients suffering from Dementia can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
AD affects various functional and structural connectivity networks in the brain which are associated with the topography, clinical phenotype, and severity of the disease. Magnetic resonance imaging studies have demonstrated successive structural and functional disconnection among brain regions supporting the idea that AD is a disconnection syndrome. The core brain network targeted by AD pathology plays a key role in sleep-wake cycling: sleep disturbance in AD may therefore establish a pathophysiological ‘vicious cycle’, whereby loss of normal restorative functions of sleep amplifies the neurodegenerative process within vulnerable neural circuitry. Moreover, alterations within and/or between the default mode network (DMN), salience network, and central executive network (CEN) are observed both in patients with AD and individuals who were at high risk for developing AD.
Anxiety also involves aberrant connectivity within and/or between resting state networks, such as the default mode network and the salience network. The aberrant connectivity can be normalized by a treatment according to the invention.

Parkinson's Disease Dementia (PDD) is characterized by changes in thinking and behaviour in a patient with a diagnosis of Parkinson's disease, an illness characterized by gradually progressive problems with movement, most commonly involving slowing of movements, a tremor present at rest, and walking instability which can cause falls.
In the vast majority of patients with PD cognitive function deteriorates over time. By 20 years of disease duration, up to 80% of patients develop Parkinson's Disease Dementia, with a mean time from onset of PD to dementia of 10 years.
Neuropsychiatric symptoms are common in PDD, and there is a high prevalence of anxiety in PDD patients.
The severity of anxiety in patients suffering from PDD can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Studies show a functional reorganization of resting state networks which are critical to generate and maintain an efficient behavioural and cognitive performance in patients suffering from PDD.
As such, Parkinson's Disease Dementia is associated with reduced connectivity in networks relevant to cognition, most prominently the default mode network.
Anxiety also involves aberrant connectivity within and/or between networks. The aberrant connectivity can be normalized by a treatment according to the invention.

Dementia with Lewy Bodies (DLB) is a type of dementia characterized by changes in sleep, behaviour, cognition, movement, and regulation of automatic bodily functions.
Core features include REM sleep behaviour disorder as well as visual hallucinations, marked fluctuations in attention or alertness, and parkinsonism (slowness of movement, trouble walking, or rigidity).
Anxiety symptoms are found to be significantly more common in DLB than in Alzheimer's disease. In fact, anxiety is recognised to be a prominent feature in DLB and is as such listed as a supporting feature in the diagnosis of DLB.
The presence of anxiety may precede the diagnosis of DLB by 4-5 years and it is argued that the combination of cognitive decline alongside anxiety should prompt consideration for a diagnosis of DLB.
The severity of anxiety in patients suffering from DLB can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
In patients suffering from DLB, resting state network (RSN) alterations can be identified. Functional MRI studies show changes in functional connectivity within and/or between the default mode network, salience network, executive network and basal ganglia/limbic network.
Anxiety also involves aberrant connectivity within and/or between resting state networks, such as the default mode network and the salience network. The aberrant connectivity can be normalized by a treatment according to the invention.

Vascular Dementia is a common type of dementia characterized by problems with reasoning, planning, judgment, memory and other thought processes. Vascular Dementia is due to brain parenchyma injury resulting from one or more cerebrovascular event (ischemic or haemorrhagic). The vascular aetiology is very varied, ranging from microvascular disease to large vessel stroke.
Patients with Vascular Dementia often have symptoms of anxiety. The prevalence of anxiety is higher in patients suffering from vascular dementia compared to patients suffering from Alzheimer's disease.
Moreover, anxiety increases the risk of development of vascular dementia.
The severity of anxiety in patients suffering from Vascular Dementia can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Functional magnetic resonance imaging reveals altered functional connectivity of resting state networks after a cerebrovascular insult. Patients show an abnormal functional connectivity within and/or between the DMN and other resting state networks.

A Fronto-Temporal Dementia (FTD) is a neurodegenerative disorder caused by progressive nerve cell loss in the brain's frontal or temporal lobes that constitute a leading cause of younger onset dementia.
Patients present with heterogeneous constellations of behavioural and psychological symptoms among which progressive changes in social conduct, lack of empathy, apathy, disinhibited behaviours, and cognitive impairments are frequently observed. While impairments are pronounced in executive and social functions, the assessment of cognitive performance is crucial for clinical diagnosis and patient management.
The behavioural variant is characterized by at least three symptoms such as disinhibition; apathy or inertia, which leads to inactivity and lack of effort; loss of sympathy or empathy; perseverative, compulsive, ritualistic behaviours or stereotypies; and hyperorality and dietary changes, associated with a prominent decline in social cognition and/or executive abilities.
Patients suffering from FTD also suffer from anxiety symptoms. Anxiety is moreover associated with an increased risk of developing FTD.
The severity of anxiety in patients suffering from FTD can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Resting state-functional magnetic resonance imaging (rs-fMRI) analysis of individuals suffering from a FTD reveals global functional deterioration and a loss of network integration. Altered functional connectivity was mainly identified within and/or between the attention network, the default mode network and in particular the salience network.
Anxiety also involves aberrant connectivity within and/or between resting state networks, such as the default mode network and the salience network. The aberrant connectivity can be normalized by a treatment according to the invention.

An Eating Disorder is a mental disorder characterised by abnormal eating behaviours that negatively affect a person's physical or mental health.
A patient suffering from an Eating Disorder may suffer from a treatment resistant form of the disorder.
Anxiety may increase the risk of developing Eating Disorders and moreover may represent a manifestation of a shared psychopathological mechanism.
The severity of anxiety in patients suffering from an Eating Disorder can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Patients suffering from an Eating Disorder and anxiety symptoms moreover tend to also suffer from suicidal ideation.
Suicidal ideation may be assessed using the Columbia Suicide Severity Rating Scale (C-SSRS).
In patients suffering from Eating Disorders, results from functional network connectivity studies indicate disrupted resting-state connectivity within and/or between executive networks, the default-mode network and the salience network.
Anxiety also involves aberrant connectivity within and/or between resting state networks, such as the default mode network and the salience network. The aberrant connectivity can be normalized by a treatment according to the invention.

Schizotypal Personality Disorder is a mental health condition marked by a consistent pattern of intense discomfort with relationships and social interactions. Patients suffering from Schizotypal Personality Disorder have unusual thoughts, speech, and behaviours, which hinder their ability to form and maintain relationships.
The condition also involves cognitive difficulties, perceptual disturbances, and paranoia.
A patient suffering from Schizotypal Personality Disorder may suffer from a treatment resistant form of the disorder.
Anxiety disorders are highly prevalent in patients with Schizotypal Personality Disorder.
The severity of anxiety in patients suffering from Schizotypal Personality Disorder can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAMA (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Patients suffering from Schizotypal Personality Disorder and anxiety symptoms moreover tend to also suffer from suicidal ideation.

Patients suffering from an Autism Spectrum Disorder (ASD), including autism, Asperger's syndrome and atypical autism, have persistent deficits in the ability to initiate and to sustain reciprocal social interaction and social communication. The condition is moreover characterized by a range of restricted, repetitive, and inflexible patterns of behaviour, interests or activities that are clearly atypical or excessive for the individual's age and sociocultural context.
The onset of the disorder is during the developmental period, but symptoms may not become fully manifest until later. Deficits are sufficiently severe to affect a patient's ability to function in personal, family, social, educational, occupational or other areas.
Patients suffering from an Autism Spectrum Disorder may also suffer from anxiety disorders.
Difficult social situations and sensory environments can increase stress and increase anxiety for patients suffering from an Autism Spectrum Disorder. Also, a sense of being misunderstood and not accepted by non-autistic people can cause anxiety. To ‘fit in’ and not be seen as different, patients might mask or camouflage. This can increase anxiety and have a negative effect on their mental health.
Moreover, other reasons that autistic people may experience anxiety include a change to routine, particularly an unexpected change and the difficulty identifying, understanding and managing emotions (also known as alexithymia).
Experiencing such high levels of anxiety can lead to exhaustion, autistic fatigue or burnout, significantly affecting a person's quality of life, such as physical and mental health, work/school and social life.
The severity of anxiety in patients suffering from an Autism Spectrum Disorder can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAMA (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Patients suffering from an Autism Spectrum Disorder and anxiety symptoms moreover tend to also suffer from suicidal ideation.
Suicidal ideation may be assessed using the Columbia Suicide Severity Rating Scale (C-SSRS).
ASD is a disorder of brain network connectivity. Neuroimaging studies indicate that ASD is related to the anomalous responses in certain brain areas, significant alteration of brain networks, including altered functional connectivity within and/or between the default mode network (DMN) and the sensory processing network, and disturbed neural synchronization between brain areas. Anxiety also involves aberrant connectivity within and/or between networks. The aberrant connectivity can be normalised by a treatment according to the invention.

Fatigue describes a feeling of exhaustion, lethargy, and decreased energy. Fatigue is experienced as a weakening or depletion of one's physical or mental resources. Even though considered as normal following a period of exertion, mental or physical, fatigue may occur in the absence of such exertion as a symptom of health conditions.
Chronic fatigue exacerbated by activity is moreover a prominent symptom in Chronic Fatigue Syndrome. In this disorder, severe fatigue is accompanied by neurocognitive, autonomic, and immunological symptoms.
A variety of abnormalities in normal sleep patterns, which may act as perpetuating factors, have been reported in Chronic Fatigue Syndrome patients.
Patients suffering from Chronic Fatigue Syndrome often also suffer from anxiety symptoms.
Fatigue in Patients suffering from Chronic Fatigue Syndrome is commonly assessed by for example the Chalder Fatigue Scale, a 14-item instrument designed to measure the severity of physical and mental symptoms in both clinical and research settings. Respondents are asked to answer questions pertaining to fatigue with one of four response choices: “better than usual,” “no more than usual,” “worse than usual,” or “much worse than usual.”
In terms of scoring, the scale can accommodate two different methods. The first weights the individual's responses as Likert-type items and uses those scores to interpret results. The second ignores the severity of responses and uses a bimodal system to categorize each answer as either problematic or not.
The severity of anxiety in patients suffering from Chronic Fatigue Syndrome can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Patients suffering from Chronic Fatigue Syndrome and anxiety symptoms moreover tend to also suffer from suicidal ideation.
Suicidal ideation may be assessed using the Columbia Suicide Severity Rating Scale (C-SSRS).
Patients suffering from Chronic Fatigue Syndrome show abnormal resting state functional connectivity, significantly correlated with the severity of their chronic fatigue.
Anxiety also involves aberrant connectivity within and/or between networks. The aberrant connectivity can be normalized by a treatment according to the invention.

Anxiety in Patients with a Traumatic Brain Injury
A traumatic brain injury (TBI) is an injury to the brain caused by an external force.
Traumatic brain injuries are characterized as primary or secondary brain injuries. A primary brain injury refers to the structural damage created during the time of impact from contact, acceleration-deceleration, and/or rotational forces. A secondary brain injury refers to the damage sustained from the subsequent cellular processes that occur from the primary injury (ie, hypoxia and/or raised intracranial pressure).
Patients suffering from TBI often experience anxiety symptoms. Patients may have anxiety in situations that did not bother them in the past.
The severity of anxiety in patients suffering from TBI can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Patients suffering from TBI and anxiety symptoms moreover tend to also suffer from suicidal ideation.
Suicidal ideation may be assessed using the Columbia Suicide Severity Rating Scale (C-SSRS).
Resting state functional connectivity analysis reveals alterations in overall functional connectivity within and/or between resting state networks, such as the DMN, the frontoparietal network, the executive network, and the sensory motor network. For instance, highly connected regions that can be found within the DMN are particularly susceptible to alterations in functional connectivity following traumatic brain injury.
Anxiety also involves aberrant connectivity within and/or between networks. The aberrant connectivity can be normalized by a treatment according to the invention.

Anxiety in Patients with Post COVID Condition
Coronavirus disease 2019 (COVID-19) is a contagious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-COV-2).
Post COVID Condition (sometimes referred to as “Long COVID”) is a multisystemic condition comprising often severe symptoms that follow a SARS-COV-2 infection. It is an often-debilitating illness that occurs in at least 10% of the infections.
The World Health Organization (WHO) defines this condition as a symptom complex which occurs within 3 months after infection, lasts at least 2 months, can fluctuate and for which there is no explanation that is not attributable to alternative diagnoses.
Post COVID Condition can include a wide range of ongoing health problems; these conditions can last weeks, months, or years and can sometimes result in disability.
Individuals suffering from Post COVID Condition most commonly report typical symptoms such as fatigue, shortness of breath and cognitive disorders such as for example difficulty thinking or concentrating (sometimes referred to as “brain fog”). However, patients may also experience respiratory and heart symptoms, neurological symptoms, for example sleep problems (for example insomnia), and digestive symptoms.
Post COVID Condition patients often experience lingering symptoms, such as anxiety, even after surviving a mild case of the disease. Anxiety in Post COVID Condition can be either a direct result of the SARS-COV-2 infection or caused by an acute SARS-COV-2 infection-related stay in hospital, in particular a stay in an intensive care unit.
Individuals suffering from Post COVID Condition induced anxiety often have fears about health and recovery, have stress about being off work and the impact on finances and worry about family and friends also getting ill. Moreover, Post COVID Condition induced anxiety leads to trouble sleeping, difficulty concentrating, difficulty remembering things, changes in mood, flashbacks, breathing dysfunction, chest pain and racing thoughts.
The severity of anxiety in patients suffering from Post COVID Condition can be assessed by using the Beck Anxiety Inventory (BAI). It can also be assessed by using the Hamilton Anxiety Rating Scale (HAM-A); the Psychic Anxiety subscale of the HAM-A (sum of items 1-6 and 14); the Anxious Mood item of the HAM-A (item 1); the Brief Psychiatric Rating Scale (BPRS) item “anxiety”.
Patients suffering from Post COVID Condition and anxiety symptoms moreover tend to also suffer from suicidal ideation.
Suicidal ideation may be assessed using the Columbia Suicide Severity Rating Scale (C-SSRS).
Functional magnetic resonance imaging of patients suffering from Post COVID Condition reveals alterations within and/or between resting state networks. Most commonly, the default mode network is affected.
Anxiety also involves aberrant connectivity within and/or between networks. The aberrant connectivity can be normalized by a treatment according to the invention.

The following Examples are listed to aid understanding of the invention and are not intended and should not be construed to limit in any way the invention set forth in the claims which follow thereafter.
Step 1: A stock solution of 5-MeO-DMT free base in 100% ethanol is prepared in a volumetric flask, so that the target dosage of 5-MeO-DMT free base to be administered via inhalation to the volunteer or patient is contained in a solution volume of 200 μl. Typical target dosages are from 1 mg to 25 mg 5-MeO-DMT. E.g. for a target dosage of 18 mg 5-MeO-DMT, 90 mg of 5-MeO-DMT will be dissolved in 100% ethanol for a final solution volume of 1 ml. Aliquots of the stock solution can then be stored in vials until further use.
Step 2:200 μl of the solution is transferred to a dosing capsule containing the drip pad (Storz & Bickel, Germany), and then the dosing capsule is closed with its lid.
Step 3: The dosing capsule filled with the 5-MeO-DMT ethanol solution is transferred to the filling chamber of a first Volcano Medic Vaporizer, which has been pre-heated with the temperature set at 55° C. Then the airflow of the vaporizer is switched on for 60 seconds at the pre-set rate of about 12 l/min. The heated air will flow through the dosing capsule, allowing the ethanol to evaporate, with the target dosage of 5-MeO-DMT being left in the capsule, as a thin layer covering the stainless-steel wire mesh. Accurate preparation of the dosing capsule can be confirmed by demonstrating that the final weight increase of the capsule compared to the weight of the empty capsule is about equal to the target dosage of 5-MeO-DMT.
Step 4: The prepared dosing capsule is removed from the filling chamber. It is then transferred to the filling chamber of a second Volcano Medic Vaporizer, which has been preheated with the temperature set at 210° C. and the airflow on for at least 5 minutes and then turned off immediately prior to transfer. An inhalation balloon with a valve (Storz & Bickel, Germany) is mounted on the socket of the filling chamber, the filling chamber is closed tightly and immediately afterwards the airflow is switched on for exactly 15 seconds at the pre-set flow rate of about 12 l/min, and then turned off. This will allow the full dose of 5-MeO-DMT to aerosolize and be distributed in approximately 3 liters of air in the inhalation balloon. Accurate aerosolization of the 5-MeO-DMT can be confirmed by demonstrating that the capsule weight has returned to about its initial weight.
Step 5: The balloon is then disconnected from the filling chamber, which automatically closes the valve. After attachment of the mouthpiece to the balloon, the aerosol is ready for immediate administration to the volunteer or patient.
Step 6: To prepare for the administration, the patient is asked to initially perform 1-2 deep inhalations with full exhalations, ending this sequence with a deep exhalation. Then, with the mouthpiece firmly held against the lips, the full and complete volume of the inhalation balloon is inhaled in one inhalation, holding the breath for 10 (+2.5) seconds, followed by a normal exhalation. After completing the inhalation procedure, the patient will be instructed to lie down.
Further details regarding the administration of 5-MeO-DMT by inhalation are disclosed in Example 1 of WO 2020/169850 A1, the contents of which is incorporated herein by reference.
5-MeO-DMT (2.0 g) was dissolved in MTBE (4 mL, 2.0 volumes) at 35 to 40° C. before being cooled to room temperature over 30 minutes. After stirring at room temperature for 50 minutes no crystallisation was observed, therefore, the batch temperature was decreased to 7 to 12° C. over 30 minutes. After stirring at 7 to 12° C. for 10 minutes crystallisation occurred. The batch was subsequently filtered following a 1 hour stir out at 7 to 12° C. After washing with MTBE (1 mL, 0.5 volumes), at 7 to 12° C., the batch was pulled dry under vacuum for 3.5 hours to yield a pale orange solid in 1.02 g (50% recovery). The isolated solid was analysed for purity by HPLC as described in WO 2020/169850 A1. The purity was found to be 99.74% area.
The results from the analysis further indicate that the level of individual impurities was below 0.10% area. Solvent analysis of sample indicated an MTBE level of 17 ppm.
5-MeO-DMT HBr was prepared on a 100 mg scale.
5-MeO-DMT free base was combined with isopropyl acetate (10 vols), and the resulting solution of 5-MeO-DMT was heated to 50° C. HBr was charged (1M in ethanol, 1 eq) in one single aliquot. The mixture was held at temperature and equilibrated for 3 hours.
After 1 hour, a suspension had formed. The suspension was finally cooled to room temperature and equilibrated for 18 hours. Solids were isolated by filtration and dried in vacuo at 40° C. for 18 hours.
An off-white crystalline material was obtained.

In this study, the affinity of three psychedelic test compounds (psilocin, DMT and 5-MeO-DMT) for 5-HT1A and 5-HT2A receptors in post-mortem human brain tissue from the hippocampus and frontal cortex, respectively, was determined using the technique of radioligand binding.
Human brain samples were obtained from the Edinburgh Sudden Death Brain Bank. All donors were sudden deaths with no prior history of coma, psychiatric or neurological disorders and under the age of 65 with a post-mortem interval of less than or equal to 72 hours.
Hippocampus was homogenised in ice-cold 0.25 M sucrose (1:30 w/v) using a motor driven Teflon pestle (12 strokes at 120 rpm). Myelin and cell debris were removed by centrifugation at 1,000 g for 10 minutes. The supernatant was stored on ice and the pellet re-homogenised in 0.25 M sucrose (1:15 w/v) and centrifuged at 750 g for 10 minutes. The supernatants were combined and diluted in ice-cold membrane preparation buffer, (1:100 w/v) using a tight-fitting glass/Teflon homogeniser (12 strokes, 800 rpm) and centrifuged at 20,500 g for 10 minutes. The pellet was resuspended in ice-cold membrane preparation buffer and incubated at 37° C. for 10 minutes before being centrifuged at 20,500 g for 10 minutes. The pellet was resuspended and centrifuged a final time to wash the tissue (20,500×g for 10 mins). The resulting pellet was then resuspended in ice-cold assay buffer at a tissue concentration equivalent to 3.125 mg wet weight of tissue/ml. All centrifugations were carried out at 4° C. The membrane preparation buffer consisted of 50 mM Tris-HCl, pH 7.7, 4 mM CaCl2) and 0.1% ascorbic acid. The assay buffer consisted of 50 mM Tris, pH 7.7, 4 mM CaCl2), 0.1% ascorbic acid and 10 μM Pargyline.
For saturation binding analysis, hippocampal membranes (400 μl; equivalent 1.25 mg wet weight tissue/tube) was incubated with 50 μl of 0.075-9.6 nM [3H]8-OH-DPAT and either 50 μl of assay buffer (total binding) or 50 μl of 1 μM WAY 100635 (non-specific binding) at 25° C. for 30 minutes. The wash buffer consisted of 50 mM Tris, pH 7.7.
In a displacement assay, hippocampal membranes (400 μl; equivalent 1.25 mg wet weight tissue/tube) were incubated with 50 μl of 0.6 nM [3H]8-OH-DPAT and either 50 μl of assay buffer (total binding) or 50 μl of 1·M WAY 100635 (non-specific binding) or 50 μl of one of the test compounds in one of ten concentrations between 1 and 10000 nM at 25° C. for 30 minutes.
Membrane bound radioactivity was recovered by filtration under vacuum through Skatron 11731 filters, pre-soaked in 0.5% polyethylenimine (PEI) using a Skatron cell harvester. Filters were rapidly washed with ice-cold wash buffer (wash setting 0,9,9) and radioactivity determined by liquid scintillation counting (1 ml Packard MV Gold scintillator).
The concentration of compound required to inhibit 50% of specific binding (IC50) and the Hill Slope were calculated by using non-linear regression. The Ki was calculated using the one-site binding model allowing for ligand depletion.
Frontal cortex was homogenised in ice-cold 0.25 M sucrose (1:30 w/v) using a motor driven Teflon pestle (12 strokes at 120 rpm). Myelin and cell debris was removed by centrifugation at 1,000 g for 10 minutes. The supernatant was stored on ice and the pellet re-homogenised in 0.25 M sucrose (1:15 w/v) and centrifuged at 750 g for 10 minutes. The supernatants were combined and diluted in ice-cold 50 mM Tris-HCl assay buffer, pH 7.4 (1:100 w/v), homogenised using a tight-fitting glass/Teflon homogeniser (12 strokes, 800 rpm) and centrifuged at 20,500 g for 10 minutes. The pellet was centrifuged a further two times to wash the tissue (20,500×g for 10 mins). The resulting pellet was then resuspended in ice-cold 50 mM Tris-HCl assay buffer, pH 7.4 at a tissue concentration equivalent to 10 mg wet weight of tissue/ml. All centrifugations were carried out at 4° C.
For saturation binding analysis, frontal cortical membranes (400 μl; equivalent to 4 mg wet weight of tissue/tube) were incubated with 50 μl of 0.00625-0.8 nM [3H]MDL-100,907 and either 50 μl of assay buffer or 50 μl of 10·M ketanserin (non-specific binding) at 25° C. for 60 minutes. The assay and wash buffer consisted of 50 mM Tris-HCl buffer pH 7.4.
In a displacement assay, frontal cortical membranes (400 μl; equivalent 4 mg wet weight tissue/tube) was incubated with 50 μl of 0.1 nM [3H]MDL-100,907 and either 50 μl of assay buffer (total binding) or 50 μl of 10·M ketanserin (non-specific binding) or 50 μl of one of the test compounds in one of ten concentrations between 1 and 10000 nM at 25° C. for 60 minutes.
Membrane bound radioactivity was recovered and determined as above. Data analysis was also as above.
The dissociation constant (Kd value) of [3H]8-OH-DPAT for 5-HT1A receptors in hippocampal membranes from post-mortem human brain tissue was determined for each of the three donors. The dissociation constants (Kd values) obtained were 0.51, 0.28 and 0.52 nM, respectively.
Mean inhibition constants (Ki values) for psilocin, DMT and 5-MeO-DMT were 48, 38 and 1.80 nM (mean n=3), respectively. All compounds gave Hill slopes approximating to unity, suggesting a one-site binding model.
The dissociation constant (Kd values) of [3H]MDL-100,907 for 5-HT2A receptors in frontal cortical membranes from post-mortem human brain tissue was determined for each of the three donors. The dissociation constants (Kd values) obtained were 0.11, 0.08 and 0.08 nM, respectively.
Mean inhibition constants (Ki values) for psilocin, DMT and 5-MeO-DMT were 37, 117 and 122 nM (mean n=3), respectively. All compounds gave Hill slopes approximating to unity, suggesting a one-site binding model.
The selectivity ratio of psilocin, DMT and 5-MeO-DMT for 5-HT2A over 5-HT1A receptors was 0.78, 3.1 and 68, respectively.
5-MeO-DMT did not induce mutation in four histidine-requiring bacterial strains (TA98, TA100, TA1535 and TA1537) of Salmonella typhimurium, and one tryptophan-requiring strain (WP2 uvrA pKM101) of Escherichia coli. These conditions included treatments at concentrations up to 5000 μg/plate (the maximum recommended concentration according to current regulatory guidelines), in the absence and in the presence of a rat liver metabolic activation system (S-9).
In order to investigate the pharmacokinetic properties of 5-MeO-DMT, three groups of 8 subjects each were formed. Subjects were administered a single dose of 6 mg; 12 mg or 18 mg 5-MeO-DMT via inhalation. Blood samples were obtained at 1; 2; 4; 7; 10; 15; 20; 30; 45 min and 1; 1.5; 2; 3; 4 hours after administration.
5-MeO-DMT concentrations were determined using LC-MS/MS. PK parameters were generated by algebraic analysis of the concentration versus time plots for each individual. The analysis was carried out using the software Phoenix WinNonlin 6.3.
Median Cmax values obtained for the three groups were 11.85 ng/ml (6 mg group), 22.90 ng/ml (12 mg group) and 38.45 ng/ml (18 mg group).
Table 1 below shows median percentage plasma concentrations relative to Cmax as determined for the time points indicated.
Pharmacokinetic measurements were also carried out for dosing schemes relying on uptitration. Substantially similar results were obtained.
Blood concentrations were also determined for the 5-MeO-DMT metabolite bufotenine. Only in few samples, concentrations were above the lower level of quantification (LLOQ) (25 pg/ml). From 15 min onwards, the bufotenine concentration was always below the LLOQ.
Substantially similar observations were made when subjects receiving an uptitration scheme were included.
A Phase 1/2 clinical trial of 5-MeO-DMT, administered via inhalation as described herein, in patients with treatment-resistant major depressive disorder (TRD) has been completed. This trial was designed in two parts. Part A was an open-label, single-arm, single-dose Phase 1 trial with two dose levels (12 mg (n=4) and 18 mg (n=4)). Part B was an open-label, single-arm Phase 2 trial applying an individualized dosing regimen with intra-patient dose escalation with 5-MeO-DMT. Patients (n=8) received at least one and up to three doses of 5-MeO-DMT (6 mg, 12 mg and 18 mg) in a single day, with higher doses only being administered if a peak experience was not achieved at the previously administered dose. The primary endpoint of Part A was to assess the safety and tolerability of single dosing of 5-MeO-DMT in patients with TRD. The primary endpoint of Part B was to assess the effects on the severity of depression, as assessed by the proportion of patients in remission on day seven after dosing, defined as a MADRS total score of less than or equal to 10.
In Part A, 3 of 4 patients in both groups (12 mg and 18 mg) experienced at least one ADR, all of which were mild and resolved spontaneously. No SAEs were reported.
Two of four patients (50%) in the 12 mg group and one of four patients (25%) in the 18 mg group had a MADRS remission on day seven after dosing, and one further patient (25%) in the 18 mg group had a MADRS clinical response on day seven after dosing. The mean MADRS change from baseline at day seven was −21.0 (−65%) in the 12 mg group and −12.8 (−41%) in the 18 mg group.
In Part B, 7 of 8 patients (87.5%) experienced at least one ADR. All ADRs resolved spontaneously. No SAEs were reported.
The primary endpoint was met with seven of eight patients (87.5%) achieving a MADRS remission on day seven (p<0.0001). The mean MADRS change from baseline at day seven was 24.4 (76%).
No clinically significant changes were observed in either Part A or Part B in any of the safety laboratory analyses, vital signs, psychiatric safety assessments or measures of cognitive function.
Results are summarized in the tables below.
The single-arm, open-label clinical trial will involve 15 adult female patients with clinically diagnosed postpartum depression (PPD).

More in particular, the patients will receive up to three doses of 5-MeO-DMT on Day 0:6 mg, 12 mg, and 18 mg.
The patients will be assessed for a peak psychedelic experience (based on a patient-scored visual analogue scale, the PE scale), sedation, and other endpoints after dosing. Follow-up visits are planned for Day 1, and Day 7 after the dosing day.
The following criteria must be met by all patients considered for clinical trial participation:
A potential patient who meets any of the following key exclusion criteria will be excluded from participation in this trial:
The primary objective of the trial is to determine the onset and 7-day durability of anti-depressive effects of a single-day individualized dosing regimen of 6 mg, 12 mg and 18 mg of 5-MeO-DMT in adult, female patients with PPD.
Secondary objectives are to determine the anti-depressive effects; the anti-anxiety effects; the effects on maternal behavior; the safety and tolerability; the intensity and duration of psychoactive effects (PsE); the impact on cognitive outcome of a single-day individualized dosing regimen of 6 mg, 12 mg and 18 mg of 5-MeO-DMT in adult, female patients with PPD.
An exploratory objective is to determine in breastmilk, blood and urine the amount of 5-MeO-DMT and metabolites, bufotenine and 5-methoxyindole-3-acetic acid (5-MIAA), measured by LC/MS/MS (metabolite identification screening may be performed, as required), following dose administration of a single-day IDR of 6 mg, 12 mg and 18 mg of 5-MeO-DMT in adult, female patients with PPD.
The primary endpoint of the study is the evaluation of the anti-depressive effects of 5-MeO-DMT by the change from baseline in MADRS assessed at Day 7.
Secondary endpoints include the anti-depressive effects of 5-MeO-DMT evaluated by
Except for a temporary, clinically non-relevant increase in heart rate and blood pressure shortly after administration of 5-MeO-DMT, no other noteworthy changes in vital parameters occurred. Assessments of ECG (at 3 hours after administration) and safety laboratory analyses (at 7 days), CADSS (at 3 hours, 1 day and 7 days) were unremarkable. The few reported adverse events (cramping left abdominal pain and headache, both on Day 0) were mild, short-lasting and resolved spontaneously by the end of the study.
With regard to the intensity of the psychedelic experience, the recorded PES score achieved upon exposure to a nominal dose of 6 mg was 17.3. This score indicated the need to proceed to the administration of a subsequent, higher dose of 12 mg, per the design of the individualised dosing regimen. The PES score achieved for this dose was 85.7 and, being. 75, indicated the occurrence of a peak psychedelic experience and the completion of the IDR for this patient.
Significantly, the patient reported a major improvement in her depressive symptoms as assessed by MADRS at the earliest assessment timepoint of 2 hours after drug administration, with the effect being maintained over time (Table 4). The patient also fulfilled standard criteria for MADRS response (at least 50% improvement from baseline) and MADRS remission (MADRS total score equal or less than 10).
Significant improvements were noted for several MADRS items in particular. The items are outlined in Table 4. While the patient's baseline scores for some items reflected absence of the symptom (reduced appetite, concentration difficulties, suicidal thoughts), items with scores reflecting severe symptoms (e.g., reduced sleep, inner tension) saw remarkable improvement.
Similarly, improvements were seen in several BPRS items, including Somatic Concerns, Anxiety, Emotional withdrawal, Guilt feelings and Tension.
Additionally, improvements in maternal functioning were evidenced by improvements in the BIMF score recorded at Day 7, as outlined in Table 5, with the total score improving by 14% from 92 to 105 (out of a possible total of 120).
Several functional domains of maternal function were also assessed, as defined by Barkin et al. The improvements in each functional domain are outlined in more detail in Table 6.
Here, noteworthy improvements in self-care, psychological well-being and management were achieved, with percentage improvements ranging from 18% (management) to (44%), % (self-care). These improvements reinforce the relationship between improvement in depressive items, as assessed by the MADRS, and improvements in maternal functioning.
It is noted that the patient scored comparatively high already before treatment. In some functional domains, the score was at the maximum value, or close to it (see Table 6), so that the scope for improvement by therapy was limited.
The highlighted aspects show that 5-MeO-DMT has a significantly improved efficacy profile compared to approved pharmacological therapies for postpartum depression and to all previously tested psychedelic agents, when used according to the present invention.
Together with the short duration of the acute psychedelic effects and the favourable safety profile, these data show that the technical problem to provide an improved psychoactive therapy in a patient with a postpartum depression is solved by the present invention.
The single-arm, open-label clinical trial will involve 15 adult patients with bipolar II disorder and a current major depressive episode.
Patients who are currently taking anti-depressive medication need to discontinue or taper over time such medication.
The patients will receive a single-day individualized 5-MeO-DMT dosing regimen via inhalation after vaporization.
More in particular, the patients will receive up to three doses of 5-MeO-DMT on the administration day (Day 0): 6 mg, 12 mg, and 18 mg.
The patients will be assessed for a peak psychedelic experience based on the patient-scored PES described above, sedation and other endpoints after dosing. Follow-up visits are planned for Day 1, and Day 7 after the dosing day.
Selection of patients is based on the following key inclusion criteria:
A potential patient who meets any of the following key exclusion criteria will be excluded from participation in this trial:
