Patent Application
20210128528
The present invention is directed to the use of a 5-HT2A serotonin receptor inverse agonist for the prophylaxis and/or treatment of psychosis or psychotic symptoms in an individual comprising administering to said individual in need thereof a therapeutically effective amount of said 5-HT2A serotonin receptor inverse agonist. In some embodiments, administering to said individual in need thereof a therapeutically effective amount of said 5-HT2A serotonin receptor inverse agonist does not result in a worsening of psychosis or psychotic symptoms such as, but not limited to, hallucinations and delusions. In some embodiments, administering to said individual in need thereof a therapeutically effective amount of said 5-HT2A serotonin receptor inverse agonist results in an improvement of psychosis or psychotic symptoms such as, but not limited to, hallucinations and delusions. In some embodiments, administering to said individual in need thereof a therapeutically effective amount of said 5-HT2A serotonin receptor inverse agonist results in an improvement of psychosis or psychotic symptoms.
Any methods and materials similar or equivalent to those described herein can be used in the practice or testing of embodiments of the present invention. The methods, devices, and materials described herein are exemplary in nature.
Many people suffer from psychosis or psychotic symptoms from a variety of causes. There is a significant unmet need for therapies to treat psychosis and psychotic symptoms, regardless of cause, but particularly when associated with diseases such as Parkinson's disease, dementia with Lewy bodies and Parkinson's disease dementia, and other conditions. These patients can often suffer from psychotic symptoms and/or neuropsychiatric symptoms including hallucinations and delusions. Most existing antipsychotics aim to treat these symptoms by blocking the dopamine D2 receptor to limit dopamine activity. However, this activity against dopamine can exacerbate motor problems common to these patients. As a result, most existing antipsychotics are avoided altogether or used with extreme caution in patients with Parkinson's disease, dementia with Lewy bodies, and Parkinson's disease dementia. This application pertains to treating psychosis or psychotic symptoms, regardless of cause.
Inverse agonists/antagonists at the serotonin 2A receptor (5HT2AR) have proven to be highly effective, mainstay therapies for the treatment of psychosis for decades. Many atypical antipsychotics, including clozapine, have been explored for their efficacy in treating a wide range of neuropsychiatric deficits. However, atypical antipsychotics target multiple receptors, and in the case of clozapine, demonstrate activity at dopamine and 5HT2C receptors. Described herein are methods of using 5HT2AR inverse agonists described to treat psychosis or psychotic symptoms.
Psychosis is an abnormal condition of the mind that involves a “loss of contact with reality”. People experiencing psychosis may exhibit personality changes and thought disorder. Depending on its severity, this may be accompanied by unusual or bizarre behavior, as well as difficulty with social interaction and impairment in carrying out daily life activities. There are several subtypes of psychosis including, but not limited to cycloid psychosis, menstrual psychosis, post partum psychosis, monthematic delusions, myxedematous psychosis, stimulant psychosis, tardive psychosis, shared psychosis, and others. Psychosis may be the result of or symptomatic of an underlyin psychiatric disorder, stress, use of psychoactive drugs, alcohol consumption, medication, trauma, a medical condition, or combination of these and/or other causes. Psychosis can even be seen in normal states, often, but not always, accompanying stress, such as hallucinating when falling asleep or waking (hypnagogic and hypnopompic hallucinations), during bereavement, as a result of sleep deprivation, or sensory deprivation or impairment, from caffeine intoxication, or from other events.
Examples of psychiatric disorders that can cause psychosis or psychotic symptoms include, but are not limited to, schizophrenia, affective (mood) disorders, including depression, severe depression, or bipolar disorder, schizoaffective disorder, brief psychotic disorder, chronic hallucinatory psychosis, schizotypal personality disorder, paranoid personality disorder, schizoid personality disorder, borderline personality disorder, major depressive disorder, bipolar disorder, especially in manic or mixed episodes, post-traumatic stress disorder, induced delusional disorder, obsessive-compulsive disorder, dissaociative disorders, and others.
Psychotic symptoms include but are not limited to hallucinations, delusions, catatonia, thought disorder, impairment of social cognition, and combinations thereof. Hallucinations are often thought of as visual, but may occur with any of the senses. Delusions are false beliefs held without adequate evidence, and may be paranoid or otherwise in nature. Catatonia describes a profoundly agitated state often characterized by either complete immobility and interaction with the world or excessive motor behavior and mental focus so as to prevent experiencing reality.
Nelotanserin, a 5HT2A inverse agonist with 80-fold selectivity over 5HT2C and inactive in a panel of 66 receptors and ion channels, is being investigated for treating psychosis or psychotic symptoms, particularly in patients diagnosed with Lewy body dementia who experience frequent visual hallucinations, and is particularly well suited for use in the treatment methods described herein.
There is a significant unmet need for therapies to treat psychosis and psychotic symptoms, regardless of cause, but particularly when associated with diseases such as Parkinson's disease, dementia with Lewy bodies and Parkinson's disease dementia, and other conditions. These patients can often suffer from psychotic symptoms and/or neuropsychiatric symptoms including hallucinations and delusions. Most existing antipsychotics aim to treat these symptoms by blocking the dopamine D2 receptor to limit dopamine activity. However, this activity against dopamine can exacerbate motor problems. As a result, most existing antipsychotics are avoided altogether or used with extreme caution in patients with Parkinson's disease, dementia with Lewy bodies, and Parkinson's disease dementia. Surprisingly and unexpectedly, Applicant has found that the 5-HT2A serotonin receptor inverse agonist nelotanserin has been effective in treating psychotic symptoms in mouse models.
Nelotanserin was characterized as an antagonist of 5-HT2A stimulation in the DiscoveRx PathHunter βarrestin2 enzyme fragment complementation assay using h5HT2A-Dx-U2OS cells (n=6-7). Cells were incubated with nelotanserin or clozapine for 90 minutes at 37° C. followed by addition of DiscoverX detection reagent for 60 minutes, after which luminescence was measured.
In vivo antagonist effects were assessed in C57Bl/6J male mice by 1: inhibition of DOI (1-(2,5-dimethoxy 4-iodophenyl)-2-amino propane hydrochloride)-induced head twitch response and 2: inhibition of PCP-induced hyperlocomotor activation. In the DOI-induced head twitch assay, mice were administered nelotanserin (1-10 mg/kg, i.p.) or vehicle 30 minutes prior to administration of the 5HT2A receptor agonist, DOI (1 mg/kg, i.p.) and observed for head twitch response over 1 hour. PCP-induced hyperlocomotion was measured in open field activity monitor chambers. Mice were administered nelotanserin (10 mg/kg, i.p.), clozapine (1 mg/kg, i.p.), or vehicle (i.p.), and their activity was monitored for 30 minutes before administration of either PCP (10 mg/kg, i.p.) or saline (i.p.) followed by an additional 30 minutes of activity monitoring. All studies were performed in a blinded and randomized manner and potencies were calculated. Clozapine was used as the basis for comparison.
Nelotanserin inhibited serotonin-induced 5HT2AR-β-arrestin 2 interactions, acting as a potent antagonist of the recruitment of β-arrestin 2 to the 5HT2A receptor (IC50 (SEM): 3.74 nM (±0.65)), and was found to be more potent than clozapine (IC50 (SEM): 67.8 nM (±12.1)). In mice, nelotanserin blocked DOI-induced head twitches in a dose-dependent manner (ED50 (95% CL): 2.4 mg/kg (1.3-4.4)), demonstrating potent in vivo antagonism of the 5HT2A agonist-induced behavior. Finally, in a mouse model of psychosis-like behavior, PCP-induced hyperlocomotor activity was effectively inhibited by nelotanserin (ED50 (95% CL): 3.0 mg/kg (1.7-5.5)), without any effect of nelotanserin on locomotor behavior on its own. This effect was comparable to the results obtained with clozapine. No significant effects on head twitches or locomotor activity were observed upon treatment of nelotanserin followed by vehicle.
The data depicted in
Thus, Nelotanserin performs as an antagonist in cell-based 5HT2A signaling assays (βarrestin2 recruitment) and in mouse models of 5HT2A block (DOI-induced head twitch) and psychosis-like behavior (PCP-induced hyperlocomotion). In all three assays, nelotanserin acts in a manner similar to clozapine, a clinically relevant atypical antipsychotic. These data suggest that nelotanserin, and other 5HT2A serotonin receptor inverse agonists may prove useful in the treatment of psychotic symptoms.

“Pharmaceutically acceptable salts, hydrates, polymorphs or solvates” is meant to indicate those salts, hydrates, polymorphs or solvates which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of a patient without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, Berge et al. (1977) J. Pharm. Sciences, Vol 6. 1-19, describes pharmaceutically acceptable salts in detail. A pharmaceutical acceptable “salt” is any acid addition salt, preferably a pharmaceutically acceptable acid addition salt, including, but not limited to, halogenic acid salts such as hydrobromic, hydrochloric, hydrofloric and hydroiodic acid salt; an inorganic acid salt such as, for example, nitric, perchloric, sulfuric and phosphoric acid salt; an organic acid salt such as, for example, sulfonic acid salts (methanesulfonic, trifluoromethan sulfonic, ethanesulfonic, benzenesulfonic or p-toluenesufonic, acetic, malic, fumaric, succinic, citric, benzoic gluconic, lactic, mandelic, mucic, pamoic, pantothenic, oxalic and maleic acid salts; and an amino acid salt such as aspartic or glutamic acid salt. The acid addition salt may be a mono- or di-acid addition salt, such as a di-hydrohalogic, di-sulfuric, di-phosphoric or di-organic acid salt. In all cases, the acid addition salt is used as an achiral reagent which is not selected on the basis of any expected or known preference for the interaction with or precipitation of a specific optical isomer of the products of this disclosure.
As used herein, the term “daily dose” refers to the amount of nelotanserin or pharmaceutically acceptable salts, hydrates, polymorphs or solvates thereof, per day that is administered or prescribed to a patient.

The compounds described herein may be formulated as pharmaceutical compositions that may comprise a pharmaceutically acceptable excipient. Conventional excipients, such as binding agents, fillers, acceptable wetting agents, tableting lubricants, and disintegrants may be used in tablets and capsules for oral administration. Liquid preparations for oral administration may be in the form of solutions, emulsions, aqueous or oily suspensions, and syrups. Alternatively, the oral preparations may be in the form of dry powder that can be reconstituted with water or another suitable liquid vehicle before use. Additional additives such as suspending or emulsifying agents, non-aqueous vehicles (including edible oils), preservatives, and flavorings and colorants may be added to the liquid preparations. Parenteral dosage forms may be prepared by dissolving the compound of the invention in a suitable liquid vehicle and filter sterilizing the solution before filling and sealing an appropriate vial or ampoule. These are just a few examples of the many appropriate methods well known in the art for preparing dosage forms.
The compounds described herein can be formulated into pharmaceutical compositions using techniques well known to those in the art. Suitable pharmaceutically-acceptable carriers, outside those mentioned herein, are known in the art; for example, see Remington, The Science and Practice of Pharmacy, 20th Edition, 2000, Lippincott Williams & Wilkins, (Editors: Gennaro, A. R., et al.).
While it is possible that, for use in the prophylaxis and/or treatment, a compound of the invention may, in an alternative use, be administered as a raw or pure chemical, it is preferable to present the compound or active ingredient as a pharmaceutical formulation or composition further comprising a pharmaceutically acceptable carrier.
The invention thus further provides pharmaceutical formulations comprising a compound of the invention or a pharmaceutically acceptable salt or derivative thereof together with one or more pharmaceutically acceptable carriers thereof and/or prophylactic ingredients. The carrier(s) must be “acceptable” in the sense of being compatible with the other ingredients of the formulation and not overly deleterious to the recipient thereof.
Pharmaceutical formulations include those suitable for oral, rectal, nasal, topical (including buccal and sub-lingual), vaginal or parenteral (including intramuscular, subcutaneous and intravenous) administration or in a form suitable for administration by inhalation, insulation or by a transdermal patch. Transdermal patches dispense a drug at a controlled rate by presenting the drug for absorption in an efficient manner with a minimum of degradation of the drug. Typically, transdermal patches comprise an impermeable backing layer, a single pressure sensitive adhesive and a removable protective layer with a release liner. One of ordinary skill in the art will understand and appreciate the techniques appropriate for manufacturing a desired efficacious transdermal patch based upon the needs of the artisan.
The compounds of the invention, together with a conventional adjuvant, carrier, or diluent, may thus be placed into the form of pharmaceutical formulations and unit dosages thereof, and in such form may be employed as solids, such as tablets or filled capsules, or liquids such as solutions, suspensions, emulsions, elixirs, gels or capsules filled with the same, all for oral use; in the form of suppositories for rectal administration; or in the form of sterile injectable solutions for parenteral (including subcutaneous) use. Such pharmaceutical compositions and unit dosage forms thereof may comprise conventional ingredients in conventional proportions, with or without additional active compounds or principles, and such unit dosage forms may contain any suitable effective amount of the active ingredient commensurate with the intended daily dosage range to be employed.
For oral administration, the pharmaceutical composition may be in the form of, for example, a tablet, capsule, suspension or liquid. The pharmaceutical composition is preferably made in the form of a dosage unit containing a particular amount of the active ingredient. Examples of such dosage units are capsules, tablets, powders, granules or a suspension, with conventional additives such as lactose, mannitol, corn starch or potato starch; with binders such as crystalline cellulose, cellulose derivatives, acacia, corn starch or gelatins; with disintegrators such as corn starch, potato starch or sodium carboxymethyl-cellulose; and with lubricants such as talc or magnesium stearate. The active ingredient may also be administered by injection as a composition wherein, for example, saline, dextrose or water may be used as a suitable pharmaceutically acceptable carrier.
Compounds of the present invention or a solvate or physiologically functional derivative thereof can be used as active ingredients in pharmaceutical compositions, specifically as 5-HT2A receptor modulators. The term “active ingredient” is defined in the context of a “pharmaceutical composition” and shall mean a component of a pharmaceutical composition that provides the primary pharmacological effect, as opposed to an “inactive ingredient” which would generally be recognized as providing no pharmaceutical benefit.
The dose when using the compounds of the present invention can vary within wide limits, and as is customary and is known to the physician, it is to be tailored to the individual conditions in each individual case. It depends, for example, on the nature and severity of the illness to be treated, on the condition of the patient, on the compound employed or on whether an acute or chronic disease state is treated or prophylaxis is conducted or on whether further active compounds are administered in addition to the compounds of the present invention. Representative doses of the present invention include, but are not limited to, about 0.001 mg to about 5000 mg, about 0.001 mg to about 2500 mg, about 0.001 mg to about 1000 mg, about 0.001 mg to about 500 mg, about 0.001 mg to about 250 mg, about 0.001 mg to about 100 mg, about 0.001 mg to about 50 mg, and about 0.001 mg to about 25 mg. Representative doses of the present invention include, but are not limited to, about 0.0001 to about 1,000 mg, about 10 to about 160 mg, about 10 mg, about 20 mg, about 40 mg, about 80 mg or about 160 mg. Multiple doses may be administered during the day, especially when relatively large amounts are deemed to be needed, for example 2, 3 or 4 doses. In some embodiments, the dose is administered once daily in the morning, twice daily, or once daily about 1 hour prior to the individual's bedtime. In some embodiments, the dose is administered about one to about four times per day, once daily in the morning, once daily about 1 hour prior to the individual's bedtime, or twice daily. Depending on the individual and as deemed appropriate from the patient's physician or caregiver it may be necessary to deviate upward or downward from the doses described herein.
The amount of active ingredient, or an active salt or derivative thereof, required for use in treatment will vary not only with the particular salt selected but also with the route of administration, the nature of the condition being treated and the age and condition of the patient and will ultimately be at the discretion of the attendant physician or clinician. In general, one skilled in the art understands how to extrapolate in vivo data obtained in a model system, typically an animal model, to another, such as a human. In some circumstances, these extrapolations may merely be based on the weight of the animal model in comparison to another, such as a mammal, preferably a human. However, more often, these extrapolations are not simply based on weights, but rather incorporate a variety of factors. Representative factors include the type, age, weight, sex, diet and medical condition of the patient, the severity of the disease, the route of administration, pharmacological considerations such as the activity, efficacy, pharmacokinetic and toxicology profiles of the particular compound employed, whether a drug delivery system is utilized, whether an acute or chronic disease state is being treated or prophylaxis is conducted, or whether further active compounds are administered in addition to the compounds of the present invention and as part of a drug combination. The dosage regimen for treating a disease condition with the compounds and/or compositions of this invention is selected in accordance with a variety of factors as cited above. Thus, the actual dosage regimen employed may vary widely and therefore may deviate from a preferred dosage regimen. One skilled in the art will recognize that dosage and dosage regimen outside these typical ranges can be tested and, where appropriate, may be used in the methods of this invention.
The desired dose may conveniently be presented in a single dose or as divided doses administered at appropriate intervals, for example, as two, three, four or more sub-doses per day. The sub-dose itself may be further divided, e.g., into a number of discrete loosely spaced administrations. The daily dose can be divided, especially when relatively large amounts are administered as deemed appropriate, into several, for example 2, 3 or 4, part administrations. If appropriate, depending on individual behavior, it may be necessary to deviate upward or downward from the daily dose indicated.
The compounds of the present invention can be administrated in a wide variety of oral and parenteral dosage forms. It will be obvious to those skilled in the art that the following dosage forms may comprise, as the active component, either a compound of the invention or a pharmaceutically acceptable salt of a compound of the invention.
For preparing pharmaceutical compositions from the compounds of the present invention, the selection of a suitable pharmaceutically acceptable carrier can be either solid, liquid or a mixture of both. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispersible granules. A solid carrier can be one or more substances which may also act as diluents, flavoring agents, solubilizers, lubricants, suspending agents, binders, preservatives, tablet disintegrating agents, or an encapsulating material.
In powders, the carrier is a finely divided solid which is in a mixture with the finely divided active component.
In tablets, the active component is mixed with the carrier having the necessary binding capacity in suitable proportions and compacted to the desired shape and size.
The powders and tablets may contain varying percentage amounts of the active compound. A representative amount in a powder or tablet may contain from 0.5 to about 90 percent of the active compound; however, an artisan would know when amounts outside of this range are necessary. Suitable carriers for powders and tablets are magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, a low melting wax, cocoa butter, and the like. The term “preparation” is intended to include the formulation of the active compound with encapsulating material as a carrier, providing a capsule in which the active component, with or without carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid forms suitable for oral administration.
For preparing suppositories, a low melting wax, such as an admixture of fatty acid glycerides or cocoa butter, is first melted and the active component is dispersed homogeneously therein, as by stirring. The molten homogenous mixture is then poured into convenient sized molds, allowed to cool, and thereby to solidify.
Formulations suitable for vaginal administration may be presented as pessaries, tampons, creams, gels, pastes, foams or sprays containing in addition to the active ingredient such carriers as are known in the art to be appropriate.
Liquid form preparations include solutions, suspensions, and emulsions, for example, water or water-propylene glycol solutions. For example, parenteral injection liquid preparations can be formulated as solutions in aqueous polyethylene glycol solution. Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose, any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables.
The compounds according to the present invention may thus be formulated for parenteral administration (e.g. by injection, for example bolus injection or continuous infusion) and may be presented in unit dose form in ampoules, pre-filled syringes, small volume infusion or in multi-dose containers with an added preservative. The pharmaceutical compositions may take such forms as suspensions, solutions, or emulsions in oily or aqueous vehicles, and may contain formulatory agents such as suspending, stabilizing and/or dispersing agents. Alternatively, the active ingredient may be in powder form, obtained by aseptic isolation of sterile solid or by lyophilization from solution, for constitution with a suitable vehicle, e.g. sterile, pyrogen-free water, before use.
Aqueous formulations suitable for oral use can be prepared by dissolving or suspending the active component in water and adding suitable colorants, flavors, stabilizing and thickening agents, as desired.
Aqueous suspensions suitable for oral use can be made by dispersing the finely divided active component in water with viscous material, such as natural or synthetic gums, resins, methylcellulose, sodium carboxymethylcellulose, or other well-known suspending agents.
Also included are solid form preparations which are intended to be converted, shortly before use, to liquid form preparations for oral administration. Such liquid forms include solutions, suspensions, and emulsions. These preparations may contain, in addition to the active component, colorants, flavors, stabilizers, buffers, artificial and natural sweeteners, dispersants, thickeners, solubilizing agents, and the like.
For topical administration to the epidermis the compounds according to the invention may be formulated as ointments, creams or lotions, or as a transdermal patch.
Ointments and creams may, for example, be formulated with an aqueous or oily base with the addition of suitable thickening and/or gelling agents. Lotions may be formulated with an aqueous or oily base and will in general also contain one or more emulsifying agents, stabilizing agents, dispersing agents, suspending agents, thickening agents, or coloring agents.
Formulations suitable for topical administration in the mouth include lozenges comprising the active agent in a flavored base, usually sucrose and acacia or tragacanth; pastilles comprising the active ingredient in an inert base such as gelatin and glycerin or sucrose and acacia; and mouthwashes comprising the active ingredient in a suitable liquid carrier.
Solutions or suspensions are applied directly to the nasal cavity by conventional means, for example with a dropper, pipette or spray. The formulations may be provided in single or multi-dose form. In the latter case of a dropper or pipette, this may be achieved by the patient administering an appropriate, predetermined volume of the solution or suspension. In the case of a spray, this may be achieved, for example, by means of a metering atomizing spray pump.
Administration to the respiratory tract may also be achieved by means of an aerosol formulation in which the active ingredient is provided in a pressurized pack with a suitable propellant. If the compounds of the present invention or pharmaceutical compositions comprising them are administered as aerosols, for example as nasal aerosols or by inhalation, this can be carried out, for example, using a spray, a nebulizer, a pump nebulizer, an inhalation apparatus, a metered inhaler or a dry powder inhaler. Pharmaceutical forms for administration of the compounds of the present invention as an aerosol can be prepared by processes well-known to a person skilled in the art. For their preparation, for example, solutions or dispersions of the compounds of the present invention in water, water/alcohol mixtures or suitable saline solutions can be employed using customary additives, for example benzyl alcohol or other suitable preservatives, absorption enhancers for increasing the bioavailability, solubilizers, dispersants and others, and, if appropriate, customary propellants, for example include carbon dioxide, CFC's, such as, dichlorodifluoromethane, trichlorofluoromethane, or dichlorotetrafluoroethane; and the like. The aerosol may conveniently also contain a surfactant such as lecithin. The dose of drug may be controlled by provision of a metered valve.
In formulations intended for administration to the respiratory tract, including intranasal formulations, the compound will generally have a small particle size for example of the order of 10 microns or less. Such a particle size may be obtained by means known in the art, for example by micronization. When desired, formulations adapted to give sustained release of the active ingredient may be employed.
Alternatively, the active ingredients may be provided in the form of a dry powder, for example, a powder mix of the compound in a suitable powder base such as lactose, starch, starch derivatives such as hydroxypropylmethyl cellulose and polyvinylpyrrolidone (PVP). Conveniently the powder carrier will form a gel in the nasal cavity. The powder composition may be presented in unit dose form for example in capsules or cartridges of, e.g., gelatin, or blister packs from which the powder may be administered by means of an inhaler:
The pharmaceutical preparations are preferably in unit dosage forms. In such form, the preparation is subdivided into unit doses containing appropriate quantities of the active component. The unit dosage form can be a packaged preparation, the package containing discrete quantities of preparation, such as packeted tablets, capsules, and powders in vials or ampoules. Also, the unit dosage form can be a capsule, tablet, cachet, or lozenge itself, or it can be the appropriate number of any of these in packaged form.
Tablets or capsules for oral administration and liquids for intravenous administration are preferred compositions.
The compounds according to the invention may optionally exist as pharmaceutically acceptable salts including pharmaceutically acceptable acid addition salts prepared from pharmaceutically acceptable non-toxic acids including inorganic and organic acids. Representative acids include, but are not limited to, acetic, benzenesulfonic, benzoic, camphorsulfonic, citric, ethanesulfonic, dichloroacetic, formic, fumaric, gluconic, glutamic, hippuric, hydrobromic, hydrochloric, isethionic, lactic, maleic, malic, mandelic, methanesulfonic, mucic, nitric, oxalic, pamoic, pantothenic, phosphoric, succinic, sulfuric, tartaric, oxalic, p-toluenesulfonic and the like, such as those pharmaceutically acceptable salts listed in Journal of Pharmaceutical Science, 66, 2 (1977); incorporated herein by reference in its entirety.
The acid addition salts may be obtained as the direct products of compound synthesis. In the alternative, the free base may be dissolved in a suitable solvent containing the appropriate acid, and the salt isolated by evaporating the solvent or otherwise separating the salt and solvent. The compounds of this invention may form solvates with standard low molecular weight solvents using methods known to the skilled artisan.
Compounds of the present invention can be converted to “pro-drugs.” The term “pro-drugs” refers to compounds that have been modified with specific chemical groups known in the art, and when administered into an individual, these groups undergo biotransformation to give the parent compound. Pro-drugs can thus be viewed as compounds of the invention containing one or more specialized non-toxic protective groups used in a transient manner to alter or to eliminate a property of the compound. In one general aspect, the “pro-drug” approach is utilized to facilitate oral absorption. A thorough discussion is provided in T. Higuchi and V. Stella, “Pro-drugs as Novel Delivery Systems,” Vol. 14 of the A. C. S. Symposium Series; and in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987, both of which are hereby incorporated by reference in their entirety.
Some embodiments of the present invention include a method of producing a pharmaceutical composition for “combination-therapy” comprising admixing at least one compound according to any of the compound embodiments disclosed herein, together with at least one known pharmaceutical agent as described herein and a pharmaceutically acceptable carrier.

Accordingly, this invention includes all modifications and equivalents of the individual matter recited in the claims appended hereto as permitted by applicable law. Moreover, any combination of the above-described elements in all possible variations thereof is encompassed by the invention unless otherwise indicated herein or otherwise clearly contradicted by context.
Specific embodiments disclosed herein may be further limited in the claims using “consisting of” or “consisting essentially of” language, rather than “comprising”. When used in the claims, whether as filed or added per amendment, the transition term “consisting of” excludes any element, step, or ingredient not specified in the claims. The transition term “consisting essentially of” limits the scope of a claim to the specified materials or steps and those that do not materially affect the basic and novel characteristic(s). Embodiments of the invention so claimed are inherently or expressly described and enabled herein.
In closing, it is to be understood that the embodiments of the invention disclosed herein are illustrative of the principles of the present invention.

As depicted in
Inverse agonists/antagonists at the serotonin 2A receptor (5HT2AR) have proven to be highly effective, mainstay therapies for the treatment of psychosis for decades. Many atypical antipsychotics, including clozapine, have been explored for their efficacy in treating a wide range of neuropsychiatric deficits. However, atypical antipsychotics target multiple receptors, and in the case of clozapine, demonstrate activity at dopamine and 5HT2C receptors. Nelotanserin is a 5HT2A inverse agonist with 80-fold selectivity over 5HT2C that was shown to be inactive in a panel of 66 receptors and ion channels. Nelotanserin is being investigated in a Phase 2 clinical trial of subjects diagnosed with Lewy body dementia who experience frequent visual hallucinations. In the nonclinical study presented here, we evaluated the in vitro characteristics of nelotanserin and examined its effects in mouse models of 5HT2AR activation and psychosis.
The competitive properties at the 5HT2AR of nelotanserin were characterized with the DiscoveRx PathHunter β-arrestin2 enzyme fragment complementation assay in h5HT2A-Dx-U2OS cells (n=6-7). Cells were incubated with nelotanserin or clozapine for 90 minutes at 37° C. followed by addition of DiscoveRx detection reagent for 60 minutes, after which luminescence was measured. In vivo effects were assessed in male C57Bl/6J mice by 1) inhibition of DOI (1-(2,5-dimethoxy 4-iodophenyl)-2-amino propane hydrochloride)-induced head twitch response and 2) inhibition of PCP-induced hyperlocomotion. In the DOIinduced head twitch assay, mice were administered nelotanserin or vehicle 30 minutes prior to administration of the 5HT2A receptor agonist, DOI (1 mg/kg, i.p.) and observed for head twitch response over 1 hour. PCP-induced hyperlocomotion was measured in open field activity monitor chambers. Mice were administered nelotanserin, clozapine, or vehicle (i.p.), and their activity was monitored for 30 minutes before administration of either PCP (10 mg/kg, i.p.) or saline (i.p.) followed by an additional 30 minutes of activity monitoring. All studies were performed in a blinded and randomized manner and potencies were calculated. Clozapine was used as the basis for comparison. Results: Nelotanserin inhibited serotonin-induced 5HT2AR-β-arrestin 2 interactions, acting as a potent antagonist of the recruitment of β-arrestin 2 to the 5HT2A receptor (IC50 (SEM): 3.74 nM (±0.65)), and was found to be more potent than clozapine (IC50 (SEM): 67.8 nM (±12.1)). In mice, nelotanserin blocked DOI-induced head twitches in a dose-dependent manner (ED50 (95% CL): 2.4 mg/kg (1.3-4.4)), demonstrating potent in vivo antagonism of the 5HT2A agonist-induced behavior. Finally, in a mouse model of psychosis-like behavior, PCP-induced hyperlocomotion was effectively inhibited by nelotanserin (ED50 (95% CL): 3.0 mg/kg (1.7-5.5)). No effect of nelotanserin alone was observed on locomotor behavior following administration of saline. This effect was comparable to the results obtained with clozapine. No significant effects on head twitches or locomotor activity were observed upon treatment of nelotanserin followed by vehicle.
Conclusions: Nelotanserin antagonizes β-arrestin 2 recruitment in cell-based 5HT2A signaling assays and in mouse models blocks the effects of 5HT2A agonism (DOI-induced head twitch) and of psychosis-like behavior (PCP-induced hyperlocomotion). In all three assays, nelotanserin acts in a manner similar to clozapine, a clinically relevant atypical antipsychotic. These data suggest that nelotanserin may prove useful in the treatment of psychotic symptoms.
