Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease that is characterized by progressive loss of motor neurons in the spinal cord, brainstem and/or the motor cortex. About 5-10% of ALS patient show familial traits; in more than 90% of patients, the disease is sporadic and does not show familial traits. The disease is fatal within about three years of diagnosis and fatality is generally due to atrophy of muscles necessary for breathing including the diaphragm.
Described herein are methods of treatment of Amyotrophic Lateral Sclerosis (ALS) comprising administration of adrenocorticotropic hormone (ACTH), or ACTH-like compound, composition and/or preparation to an individual in need thereof. In some instances, ALS is associated with dysregulation of adrenal activity and/or abnormal secretion of ACTH. In some instances, normal levels of ACTH protect against loss of motor coordination and prevents degeneration of myelinated axons. In some instances, secretion of abnormal physiological levels of ACTH is associated with loss of motor neurons and/or motor function and/or muscle strength with subsequent manifestation of symptoms of ALS. Accordingly, administration of adrenocorticotropic hormone (ACTH), or ACTH-like compound, composition and/or preparation to an individual in need thereof, as described herein, provides neuroprotection, or in some instances, a neurotrophic effect, thereby alleviating symptoms of ALS. Further, administration of adrenocorticotropic hormone (ACTH), or ACTH-like compound, composition and/or preparation to an individual in need thereof, has an anti-inflammatory effect (e.g., reduction in release of neuroinflammatory cytokines), thereby alleviating symptoms of ALS.
Accordingly, in some embodiments, the methods of treatment of ALS described herein comprise administration of adrenocorticotropic hormone (ACTH) peptide, or fragment, analog, complex or aggregate thereof, or any combination thereof, to an individual in need thereof (e.g., an individual suffering from, suspected of having or predisposed to ALS) in doses and/or dosing regimens that allow for maintenance or restoration of the beneficial effects of ACTH, while reducing or reversing any detrimental effects caused by abnormal physiological levels of ACTH. In some embodiments, the methods of treatment of ALS described herein comprise administration of adrenocorticotropic hormone (ACTH) to an individual in need thereof (e.g., an individual suffering from, suspected of having or predisposed to ALS) in doses and/or dosing regimens such that physiological levels of ACTH in the individual are maintained, or rendered partially or substantially normal.

The novel features of the invention are set forth with particularity in the appended claims. A better understanding of the features and advantages of the present invention will be obtained by reference to the following detailed description that sets forth illustrative embodiments, in which the principles of the invention are utilized, and the accompanying drawings of which:
Provided herein, in some embodiments, are methods of treatment of ALS comprising administration of ACTH to an individual in need thereof. ALS is a disease of motor neurons. Skeletal muscles are innervated by a group of neurons (lower motor neurons) located in the ventral horns of the spinal cord which project out the ventral roots to the muscle cells. These nerve cells are themselves innervated by the corticospinal tract or upper motor neurons that project from the motor cortex of the brain. In some instances, ALS is associated with a degeneration of the ventral horns of the spinal cord, as well as atrophy of the ventral roots. In the brain, motor neuron atrophy may be present in the frontal and/or the temporal lobes. In some instances, motor neuron degeneration in ALS is associated with adrenal dysregulation and/or abnormal levels of ACTH.
ACTH is a hormone that is secreted by the pituitary gland and is a part of the hypothalamus-pituitary-adrenal (HPA) axis that maintains the stress response and homeostasis in the body. In some instances ACTH plays a role in motor neuron function. Physiologically, the principal effects of ACTH are stimulation of the adrenal cortex with subsequent increased production of glucocorticosteroids and/or cortisol from the adrenal cortex. ACTH levels are tightly regulated in the body via a negative feedback loop wherein glucocorticosteroids suppress the release of corticotropin release hormone (CRH) from the pituitary and CRH-mediated release of ACTH. In some instances, cortisol helps restore homeostasis after stress. In some instances, changed patterns of serum cortisol levels are observed in connection with abnormal ACTH levels. In some instances, prolonged ACTH-mediated secretion of abnormal levels of cortisol (e.g., higher or lower levels of cortisol compared to cortisol levels in normal individuals) has detrimental effects. Thus, any perturbation in the levels of ACTH has profound physiological implications. The treatment of ALS presents unique challenges. In some instances, current treatment regimens are directed to alleviation of symptoms of ALS and improving quality of life for patients; however, such treatments lengthen survival only by a few months. Current treatment regimens do not address the unmet medical need for therapies that address the underlying etiology of ALS and/or delay the progression of the disease.
In one aspect, the methods of treatment provided herein, comprising administration of ACTH or ACTH-like compounds or preparations to individuals in need thereof, reduce inflammation (e.g., neuroinflammation), thereby alleviating symptoms of ALS such as inflammation of motor neurons and/or musclature which affects, for example, the ability to swallow, or the ability to breathe. In another aspect, such methods delay disease progression. For example, where an individual suffering from ALS has paralysis on the left side of the body, administration of ACTH or ACTH-like compounds or preparations described herein delays further deterioration of the patient's condition, such as progression of paralysis to the right side of the patient's body.
Advantageously, in some embodiments, the methods of treatment of ALS described herein comprise administration of adrenocorticotropic hormone (ACTH) to an individual in need thereof in doses and/or dosing regimens such that, for example, any dysregulation in the HPA axis is remedied or partially remedied, thereby alleviating the symptoms of ALS and/or delaying progressive neurodegeneration associated with ALS, i.e., providing a neuroprotective effect. In certain embodiments, the doses and/or dosing regimens described herein are designed to minimize any abrupt shifts in ACTH levels in an individual (e.g., a surge, or a drop in levels of ACTH). In some embodiments, the methods of treatment of ALS described herein delay, reduce or reverse damage to motor neurons, thereby allowing for long term survival of individuals diagnosed with, suspected of having, or predisposed to ALS.
In some other embodiments, the methods of treatment of ALS described herein comprise administration of adrenocorticotropic hormone (ACTH) to an individual in need thereof in doses and/or dosing regimens such that, for example, the circadian rhythm and/or diurnal ACTH and/or cortisol levels of individuals diagnosed with, suspected of having, or predisposed to ALS trend towards the circadian rhythm and/or diurnal ACTH and/or cortisol levels of normal individuals, thereby alleviating the symptoms of ALS and/or delaying progressive neurodegeneration associated with ALS. In some embodiments, the methods of treatment of ALS described herein normalize ACTH levels and/or promote long term survival of an individual suffering from, suspected of having or predisposed to ALS compared to an individual who is not treated with ACTH or ACTH-like compounds and preparations described herein.
In yet other embodiments, the methods of treatment of ALS described herein comprise administration of adrenocorticotropic hormone (ACTH) or ACTH-like compounds or preparations to an individual pre-disposed to ALS (e.g., an individual having a family history of ALS, or a mutation in SOD1) in doses and/or dosing regimens such that onset of ALS is delayed.
Amyotrophic Lateral Sclerosis (also called Motor Neuron Disease (MND), or Lou Gehrig's disease or Maladie de Charcot) is a progressive fatal neuromuscular disorder that is characterized by weakness, muscle wasting, and fasciculations (increased reflexes). Cognitive funtion is retained except where ALS is associated with dementia. The disease primarily affects motor neurons and is characterized by progressive degeneration of the motor neurons in the cerebral cortex, brainstem nuclei and anterior horns of the spinal cord. Individuals afflicted by the disease exhibit weakness of limbs, and difficulty in speech and swallowing. The weakness progresses to respiratory impairment and the disease is usually fatal and half of all patients die within about 3 years of onset of symptoms.
About 5-10% of ALS patients exhibit familial traits. About 20-30% of familial ALS patients exhibit a mutation in their copper/zinc superoxide dismutase (SOD1) gene. However, in greater than 90% of ALS patients, the disease is sporadic and the patients do not exhibit familial traits. In some instances, sporadic ALS patients exhibit Bunina bodies in motor neurons and are a pathological marker of ALS.
Neurons and glial cells (e.g., astrocytes) make up the neural framework in the brain. Astrocytes are responsible for maintenance of glutamate levels including the uptake and breakdown of glutamate. In some instances, the failure of astrocytes to sequester glutamate contributes to excess levels of glutamate and/or development of excitotoxicity. In some instances, ALS is associated with synaptic excitotoxicity that contributes to vulnerability of neurons to degeneration. In some instances, ALS patients exhibit higher levels of glutamate in spinal fluid and serum compared to levels of glutamate in spinal fluid and serum of individuals not suffering from ALS.
Glial cells play a role in maintenance of homeostasis in the brain. Activated glia secrete neutrophic agents including neuronal growth factor (NGF), brain-derived neutrophic factor (BDNF), neutrophin 3 (NT3), basic fibroblast growth factor (bFGF) or the like. Glial cells also counteract neuroinflammation by secretion of anti-inflammatory molecules such as IL-10, Apolipoprotein E, IL-1 receptor antagonist or the like. Thus glial activation protects the brain from the effects of stress or injury. Aberrant glial activation is accompanied by overproduction of pro-inflammatory cytokines, chemokines and reactive oxygen species. In some instances, aberrant glial activation is caused by excess glutamate. In some instances, pro-inflammatory cytokines and/or oxidative stress propagate the cycle of chronic glial activation. In some instances, ALS patients show increased levels of pro-inflammatory cytokines in spinal cord tissue and Cerebrospinal fluid (CSF) compared to controls.
Familial ALS is associated with genetic mutations in the Superoxide Dismutase 1 gene (SOD1). Mutations in SOD1 are “gain of function” mutations. In some instances, defects in SOD1 cause accumulation of free radicals. In some instances, familial ALS patients with mutations in the SOD1 gene exhibit decreased levels of VEGF in the cerebrospinal fluid compared to controls. In some instances, mutations in the SOD1 gene are associated with decreased expression of VEGF receptors on the surface of motor neurons. In some instances, under-expression of VEGF receptors is associated with degeneration of motor neurons.
ALS is a chronic disease, often having an asymptomatic phase spanning 4-5 decades. During the asymptomatic phase, peripheral motor axons are maintained by monocyte populations. The onset of ALS is a non symptomatic stage when there is retraction of motor axons from their synapses onto muscles. In some instances, neuroinflammation and/or oxidative stress in muscles and/or mitochondrial dysfunction and/or glutamate excitotoxicity and/or reduced expression of VEGF receptors is associated with onset of ALS. In some instances, mutations in SOD1 gene and/or aberrant serum levels of ACTH and/or cortisol are associated with onset of ALS. During the symptomatic phase of ALS, unknown mechanisms result in deleterious immune response with subsequent neuroinflammation and neurodegeneration. The symptomatic phase of ALS is characterized by damage to microglia and astrocytes, loss of muscle strength and slurred speech. In the final stages of the disease, there is paralysis and muscle atrophy. In some embodiments, therapeutic intervention at onset of disease, or in early stages of disease, includes modulating abnormal glutamate metabolism associated with astrocytes. In some embodiments, therapeutic intervention in later stages of disease includes modulating excitoxicity associated with astrocytes and/or modulating aberrant activation of glial cells, thereby delaying progression of disease. In some instances, therapeutic intervention in ALS includes inducing overexpression of VEGF, thereby reducing or delaying neurodegeneration.
ACTH is a 39 amino acid peptide hormone secreted by the anterior pituitary gland. ACTH is secreted from the anterior pituitary in response to corticotropin-releasing hormone (CRH) that is secreted from the hypothalamus. The release of ACTH stimulates the adrenal cortex with subsequent increased production of glucocorticosteroids and/or cortisol from the adrenal cortex.
ACTH is synthesized from a precursor polypeptide pre-pro-opiomelanocortin (pre-POMC). The removal of the signal peptide during translation produces a 267 amino acid polypeptide POMC. POMC undergoes a series of post-translational modifications to yield various polypeptide fragments including and not limited to ACTH, β-lipotropin, γ-lipotropin, α, β, γ-Melanocyte Stimulating Hormone (MSH) and β-endorphin. POMC, ACTH and β-lipotropin are also secreted from the pituitary gland in response to the hormone corticotropin-releasing hormone (CRH). In some embodiments, the first 13 amino acids of ACTH1-39 are cleaved to form α-melanocyte-stimulating hormone (α-MSH).
In some instances, multiple hypothalamic, pituitary, and peripheral factors regulate stress-mediated or inflammation-induced POMC expression and/or ACTH secretion. Essential cellular functions maintaining metabolic and neuroendocrine control require a homeostatic, non-stressed pattern of ACTH and glucocorticoid secretion. ACTH secretion is characterized by both circadian periodicity and ultradian pulsatility that is generated by CRH release and is also influenced by peripheral corticosteroids. Thus, ACTH secretion peaks at about before 7 am and nadir adrenal steroid secretion occurs between about 11 pm and 3 am, with periodic secretory bursts occurring throughout the day. Serum cortisol levels also exhibit a similar pattern of circadian periodicity. These rhythms are further reinforced by visual cues and the light-dark cycle. In some instances, stress results in increased ACTH pulse amplitude. In some instances, ALS is associated with abnormality in the circadian periodicity and ultradian pulsatility of ACTH and/or cortisol levels in the body.
In some instances, an abnormality in ACTH levels is associated with inflammation (e.g., increased release of pro-inflammatory cytokines). In some instances, an abnormality in ACTH levels is associated with reduced VEGF secretion. In some instances, reduced VEGF secretion is associated with reduced growth of new blood vessels and inadequate oxygen supply to tissues (e.g., neurons and/or muscles).
In some instances, ACTH promotes axonal regeneration. In some instances, ACTH acts as a neutrophic factor. In some instances, endogenous ACTH increases muscle action potential. In some instances, ACTH levels in the body increase upon activation of certain glutamate receptors such as the NMDA receptors. In some other instances, excitotoxicty increases or decreases secretion of ACTH.
In some instances, ACTH regulates astrocyte response by binding to melanocortin receptors. In some instances, ACTH suppresses neuroinflammation associated with ALS by binding to melanocortin receptors. In some instances, ACTH regulates migration of inflammatory cells and maintains the integrity of the blood brain barrier.

Any ACTH peptide, fragment, complex, aggregate, or analog or homolog thereof described above or below retains ACTH-like activity. As used herein, “ACTH-like activity”, in some embodiments, may refer to activity of ACTH1-39 peptide which is responsible for (1) steroidogenesis via interaction at, for example, melanocortin receptor MCR2, and/or (2) neuroprotective and/or anti-inflammatory activity mediated via interaction of ACTH, or fragment, anolog or homolog thereof at, for example, melanocotin receptors 1 and 3 (MCR1 and MCR3). Thus ACTH-like activity for a fragment arises from different domains of the ACTH1-39 peptide. Accordingly, in one embodiment, ACTH-like activity at, for example, MCR2, resides in residues 14-39 of the ACTH1-39 peptide. In a different embodiment, ACTH-like activity at, for example, MCR1 and MCR3, resides in residues 6-9 of the ACTH1-39 peptide.
The term “ACTH peptide, or fragment, analog, complex or aggregate thereof” includes, in addition to embodiments described above or below, a peptide of formula
or a fragment, complex, aggregate, or analog thereof, or any combination thereof, or a peptide fragment of formula:
or a fragment, complex, aggregate, or analog thereof, or any combination thereof, or a peptide fragment of formula:
or a fragment, complex, aggregate, or analog thereof, or any combination thereof.
The term “ACTH peptide, or fragment, analog, complex or aggregate thereof” also includes, in certain embodiments, pre-POMC, POMC, β-lipotropin, γ-lipotropin, Melanocyte Stimulating Hormone (α-MSH, □-MSH, □-MSH), β-endorphin, or the like, or any other polypeptide fragment that is a post-translational product of the POMC gene. POMC genes for various species are found in the NCBI GenBank including and not limited to human POMC transcript variant 1, mRNA, (NCBI Accession number NM_001035256), human POMC transcript variant 2, mRNA, (NCBI Accession number NM_000939), swine pro-opiomelanocortin, mRNA (NCI Accession number S73519), swine proopiomelanocortin protein (POMC) gene (NCBI Accession number EU184858), rat proopiomelanocortin (POMC) gene (NCBI Accession number K01877), or the like. Other examples of POMC genes include, for example, catfish POMC gene described in Animal Genetics, 2005, 36, 160-190. Melanocortin peptides, including ACTH and alpha, beta and gamma MSH derive from post-translational modification of POMC. A number of melanocortin peptides share an invariant sequence of four amino acids, His-Phe-Arg-Trp (SEQ ID NO: 10), which also correspond to residues 6-9 of ACTH and alpha-MSH. Accordingly, also contemplated within the scope of embodiments presented herein, is the use of amino acid sequences that correspond to alpha MSH, beta MSH or gamma MSH. See Catania et al., Pharmacol. Rev. 2004, 56: 1-29. The term “ACTH peptide, or fragment, analog, complex or aggregate thereof” includes, in addition to embodiments described above or below, also includes, an antibody that binds to melanocortin receptors and possess ACTH-like activity.
The term “ACTH peptide, or fragment, analog, complex or aggregate thereof” includes, in addition to embodiments described above or below, synthetic preparations of ACTH that are commercially available including and not limited to ACTHAR® powder for injection or gel, Synacthen®, Adrenomone®, or the like.

The term “prodrug” refers to a precursor molecule that is a derivative of ACTH or ACTH fragments or analogs thereof that is suitable for incorporation in any dosage form described herein. A “prodrug” refers to a precursor compound that is converted into active compound in vivo. Prodrugs are often useful because, in some situations, they may be easier to administer than the parent drug. They may, for instance, be bioavailable by oral administration whereas the parent is not. The prodrug may also have improved solubility in pharmaceutical compositions over the parent drug. In some embodiments, prodrugs facilitate transmittal across a cell membrane where water solubility is detrimental to mobility but which then is metabolically hydrolyzed to the carboxylic acid, the active entity, once inside the cell where water-solubility is beneficial. As non-limiting examples, a prodrug of ACTH or fragment of analog thereof is metabolically stable and is not degraded in the stomach.
Prodrugs are generally drug precursors that, following administration to a subject and subsequent absorption, are converted to an active, or a more active species via some process, such as conversion by a metabolic pathway. Some prodrugs have a chemical group present on the prodrug that renders it less active and/or less labile and/or confers solubility or some other property to the drug. Once the chemical group has been cleaved and/or modified from the prodrug the active drug is generated. In some embodiments, a prodrug of ACTH or fragment or analog thereof is an alkyl ester of the parent compound such as, for example, methyl ester, ethyl ester, n-propyl ester, iso-propyl ester, n-butyl ester, sec-butyl ester, tert-butyl ester or any other ester.
Provided herein are methods of treating ALS comprising administration of ACTH to individuals in need thereof. In some embodiments, methods of treatment of ALS described herein allow for early intervention upon detection of loss of muscle strength and/or slurred speech and prior to onset of twitches/paralysis. In some embodiments, upon detection of a mutation in SOD1, the methods of treatment of ALS described herein allow for prophylactic administration of ACTH in familial ALS patients and/or patients who are pre-disposed to ALS and allow for delayed onset of disease or for slowing down progression of disease.
In some instances, secretion of abnormal physiological levels of ACTH (e.g., lower levels or higher physiological levels of ACTH compared to normal physiological levels of ACTH) is associated with loss of motor neurons and/or motor function and/or muscle strength with subsequent manifestation of symptoms of ALS. Accordingly, in some embodiments, administration of ACTH allows for correction of abnormal physiological levels of ACTH, thereby alleviating symptoms of ALS and/or slowing down disease progression.

Exemplary carrier materials include, e.g., binders, suspending agents, disintegration agents, filling agents, surfactants, solubilizers, stabilizers, lubricants, wetting agents, diluents, and the like.
Moreover, the pharmaceutical compositions described herein, which include a ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, are formulated into any suitable dosage form, including but not limited to, aqueous oral dispersions, liquids, gels, syrups, elixirs, slurries, suspensions and the like, for oral ingestion by a patient to be treated, solid oral dosage forms, aerosols, controlled release formulations, fast melt formulations, effervescent formulations, lyophilized formulations, tablets, powders, pills, dragees, capsules, delayed release formulations, extended release formulations, pulsatile release formulations, multiparticulate formulations, and mixed immediate release and controlled release formulations. In some embodiments, a formulation comprising a ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, is a solid drug dispersion. A solid dispersion is a dispersion of one or more active ingredients in an inert carrier or matrix at solid state prepared by the melting (or fusion), solvent, or melting-solvent methods. (Chiou and Riegelman, Journal of Pharmaceutical Sciences, 60, 1281 (1971)). The dispersion of one or more active agents in a solid diluent is achieved without mechanical mixing. Solid dispersions are also called solid-state dispersions. In some embodiments, any ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, described is formulated as a spray dried dispersion (SDD). An SDD is a single phase amorphous molecular dispersion of a drug in a polymer matrix. It is a solid solution prepared by dissolving the drug and a polymer in a solvent (e.g., acetone, methanol or the like) and spray drying the solultion. The solvent rapidly evaporates from droplets which rapidly solidifies the polymer and drug mixture trapping the drug in amorphous form as an amorphous molecular dispersion. In some embodiments, such amorphous dispersions are filled in capsules and/or constituted into powders for reconstitution. Solubility of an SDD comprising a drug is higher than the solubility of a crystalline form of a drug or a non-SDD amorphous form of a drug. In some embodiments of the methods described herein, ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, are administered as SDDs constituted into appropriate dosage forms described herein.
Pharmaceutical preparations for oral use are optionally obtained by mixing one or more solid excipient with a ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, optionally grinding the resulting mixture, and processing the mixture of granules, after adding suitable auxiliaries, if desired, to obtain tablets or dragee cores. Suitable excipients include, for example, fillers such as sugars, including lactose, sucrose, mannitol, or sorbitol; cellulose preparations such as, for example, maize starch, wheat starch, rice starch, potato starch, gelatin, gum tragacanth, methylcellulose, microcrystalline cellulose, hydroxypropylmethylcellulose, sodium carboxymethylcellulose; or others such as: polyvinylpyrrolidone (PVP or povidone) or calcium phosphate. If desired, disintegrating agents are added, such as the cross linked croscarmellose sodium, polyvinylpyrrolidone, agar, or alginic acid or a salt thereof such as sodium alginate. In some embodiments, a prodrug of the ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, is used in preprations for oral use.
Dragee cores are provided with suitable coatings. For this purpose, concentrated sugar solutions are generally used, which optionally contain gum arabic, talc, polyvinylpyrrolidone, carbopol gel, polyethylene glycol, and/or titanium dioxide, lacquer solutions, and suitable organic solvents or solvent mixtures. Dyestuffs or pigments are optionally added to the tablets or dragee coatings for identification or to characterize different combinations of active compound doses.
In some embodiments, the solid dosage forms disclosed herein are in the form of a tablet, (including a suspension tablet, a fast-melt tablet, a bite-disintegration tablet, a rapid-disintegration tablet, an effervescent tablet, or a caplet), a pill, a powder (including a sterile packaged powder, a dispensable powder, or an effervescent powder) a capsule (including both soft or hard capsules, e.g., capsules made from animal-derived gelatin or plant-derived HPMC, or “sprinkle capsules”), solid dispersion, solid solution, bioerodible dosage form, controlled release formulations, pulsatile release dosage forms, multiparticulate dosage forms, pellets, granules, or an aerosol. In other embodiments, the pharmaceutical formulation is in the form of a powder. In still other embodiments, the pharmaceutical formulation is in the form of a tablet, including but not limited to, a fast-melt tablet. Additionally, pharmaceutical formulations of a ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, are optionally administered as a single capsule or in multiple capsule dosage form. In some embodiments, the pharmaceutical formulation is administered in two, or three, or four, capsules or tablets.
In another aspect, dosage forms include microencapsulated formulations. In some embodiments, one or more other compatible materials are present in the microencapsulation material. Exemplary materials include, but are not limited to, pH modifiers, erosion facilitators, anti-foaming agents, antioxidants, flavoring agents, and carrier materials such as binders, suspending agents, disintegration agents, filling agents, surfactants, solubilizers, stabilizers, lubricants, wetting agents, and diluents.
Exemplary microencapsulation materials useful for delaying the release of the formulations including a ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, include, but are not limited to, hydroxypropyl cellulose ethers (HPC) such as Klucel® or Nisso HPC, low-substituted hydroxypropyl cellulose ethers (L-HPC), hydroxypropyl methyl cellulose ethers (HPMC) such as Seppifilm-LC, Pharmacoat®, Metolose SR, Methocel®-E, Opadry YS, PrimaFlo, Benecel MP824, and Benecel MP843, methylcellulose polymers such as Methocel®-A, hydroxypropylmethylcellulose acetate stearate Aqoat (HF-LS, HF-LG, HF-MS) and Metolose®, Ethylcelluloses (EC) and mixtures thereof such as E461, Ethocel®, Aqualon®-EC, Surelease®, Polyvinyl alcohol (PVA) such as Opadry AMB, hydroxyethylcelluloses such as Natrosol®, carboxymethylcelluloses and salts of carboxymethylcelluloses (CMC) such as Aqualon®-CMC, polyvinyl alcohol and polyethylene glycol co-polymers such as Kollicoat monoglycerides (Myverol), triglycerides (KLX), polyethylene glycols, modified food starch, acrylic polymers and mixtures of acrylic polymers with cellulose ethers such as Eudragit® EPO, Eudragit® L30D-55, Eudragit® FS 30D Eudragit® L100-55, Eudragit® L100, Eudragit® S100, Eudragit® RD 100, Eudragit® E100, Eudragit® L12.5, Eudragit® 512.5, Eudragit® NE30D, and Eudragit® NE 40D, cellulose acetate phthalate, sepifilms such as mixtures of HPMC and stearic acid, cyclodextrins, and mixtures of these materials.
The pharmaceutical solid oral dosage forms including formulations described herein, which include a ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, are optionally further formulated to provide a controlled release (also known as modified release) of the ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof. As used herein, a modified release or controlled release refers to the release of the ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, from a dosage form in which it is incorporated according to a desired profile over an extended period of time. Such modified and/or controlled release profiles include, for example, sustained release, prolonged release, pulsatile release, and delayed release profiles. In contrast to immediate release compositions, controlled release or modified release compositions allow delivery of an agent to a individual over an extended period of time according to a predetermined profile. Such release rates provide levels of ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, for an extended period of time and thereby provide a longer period of pharmacologic response while minimizing side effects as compared to conventional rapid release dosage forms. Such longer periods of response provide for many inherent benefits that are not achieved with the corresponding short acting, immediate release preparations.
In other embodiments, the formulations described herein, which include a ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, are delivered using a pulsatile dosage form. A pulsatile dosage form is capable of providing one or more immediate release pulses at predetermined time points after a controlled lag time or at specific sites. Pulsatile dosage forms including the formulations described herein, which include a ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, are optionally administered using a variety of pulsatile formulations that include, but are not limited to, those described in U.S. Pat. Nos. 5,011,692, 5,017,381, 5,229,135, and 5,840,329. Other pulsatile release dosage forms suitable for use with the present formulations include, but are not limited to, for example, U.S. Pat. Nos. 4,871,549, 5,260,068, 5,260,069, 5,508,040, 5,567,441 and 5,837,284.
In further embodiments, the formulations described herein, which include a ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, are delivered as immediate release formulations (e.g., intravenously).
Additional embodiments include oral administration of an ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof. Oral administration is optionally in the form of a solid dosage form (e.g., a gelatin capsule or the like), or liquid dosage form. Liquid formulation dosage forms for oral administration are optionally aqueous suspensions selected from the group including, but not limited to, pharmaceutically acceptable aqueous oral dispersions, emulsions, solutions, elixirs, gels, and syrups. See, e.g., Singh et al., Encyclopedia of Pharmaceutical Technology, 2nd Ed., pp. 754-757 (2002). In addition to the ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, the liquid dosage forms optionally include additives, such as: (a) disintegrating agents; (b) dispersing agents; (c) wetting agents; (d) at least one preservative, (e) viscosity enhancing agents, (f) at least one sweetening agent, and (g) at least one flavoring agent. In some embodiments, the aqueous dispersions further includes a crystal-forming inhibitor.
In some embodiments, the pharmaceutical formulations described herein are self-emulsifying drug delivery systems (SEDDS). Emulsions are dispersions of one immiscible phase in another, usually in the form of droplets. Generally, emulsions are created by vigorous mechanical dispersion. SEDDS, as opposed to emulsions or microemulsions, spontaneously form emulsions when added to an excess of water without any external mechanical dispersion or agitation. An advantage of SEDDS is that only gentle mixing is required to distribute the droplets throughout the solution. Additionally, water or the aqueous phase is optionally added just prior to administration, which ensures stability of an unstable or hydrophobic active ingredient. Thus, the SEDDS provides an effective delivery system for oral and parenteral delivery of hydrophobic active ingredients. In some embodiments, SEDDS provides improvements in the bioavailability of hydrophobic active ingredients. Methods of producing self-emulsifying dosage forms include, but are not limited to, for example, U.S. Pat. Nos. 5,858,401, 6,667,048, and 6,960,563.
Suitable intranasal formulations include those described in, for example, U.S. Pat. Nos. 4,476,116, 5,116,817 and 6,391,452. Nasal dosage forms generally contain large amounts of water in addition to the active ingredient. Minor amounts of other ingredients such as pH adjusters, emulsifiers or dispersing agents, preservatives, surfactants, gelling agents, or buffering and other stabilizing and solubilizing agents are optionally present.
For administration by inhalation, the ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, is optionally in a form as an aerosol, a mist or a powder. Pharmaceutical compositions described herein are conveniently delivered in the form of an aerosol spray presentation from pressurized packs or a nebuliser, with the use of a suitable propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide or other suitable gas. In the case of a pressurized aerosol, the dosage unit is determined by providing a valve to deliver a metered amount. Capsules and cartridges of, such as, by way of example only, gelatin for use in an inhaler or insufflator are formulated containing a powder mix of the ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, and a suitable powder base such as lactose or starch.
Buccal formulations that include a ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, include, but are not limited to, U.S. Pat. Nos. 4,229,447, 4,596,795, 4,755,386, and 5,739,136. In addition, the buccal dosage forms described herein optionally further include a bioerodible (hydrolysable) polymeric carrier that also serves to adhere the dosage form to the buccal mucosa. The buccal dosage form is fabricated so as to erode gradually over a predetermined time period, wherein the delivery of the ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, is provided essentially throughout. Buccal drug delivery avoids the disadvantages encountered with oral drug administration, e.g., slow absorption, degradation of the active agent by fluids present in the gastrointestinal tract and/or first-pass inactivation in the liver. The bioerodible (hydrolysable) polymeric carrier generally comprises hydrophilic (water-soluble and water-swellable) polymers that adhere to the wet surface of the buccal mucosa. Examples of polymeric carriers useful herein include acrylic acid polymers and co, e.g., those known as “carbomers” (Carbopol®, which may be obtained from B.F. Goodrich, is one such polymer). Other components also be incorporated into the buccal dosage forms described herein include, but are not limited to, disintegrants, diluents, binders, lubricants, flavoring, colorants, preservatives, and the like. For buccal or sublingual administration, the compositions optionally take the form of tablets, lozenges, or gels formulated in a conventional manner.
Transdermal formulations of a ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, are administered for example by those described in U.S. Pat. Nos. 3,598,122, 3,598,123, 3,710,795, 3,731,683, 3,742,951, 3,814,097, 3,921,636, 3,972,995, 3,993,072, 3,993,073, 3,996,934, 4,031,894, 4,060,084, 4,069,307, 4,077,407, 4,201,211, 4,230,105, 4,292,299, 4,292,303, 5,336,168, 5,665,378, 5,837,280, 5,869,090, 6,923,983, 6,929,801 and 6,946,144.
The transdermal formulations described herein include at least three components: (1) a formulation of a ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof; (2) a penetration enhancer; and (3) an aqueous adjuvant. In addition, transdermal formulations include components such as, but not limited to, gelling agents, creams and ointment bases, and the like. In some embodiments, the transdermal formulation further includes a woven or non-woven backing material to enhance absorption and prevent the removal of the transdermal formulation from the skin. In other embodiments, the transdermal formulations described herein maintain a saturated or supersaturated state to promote diffusion into the skin.
In some embodiments, formulations suitable for transdermal administration of a ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, employ transdermal delivery devices and transdermal delivery patches and are lipophilic emulsions or buffered, aqueous solutions, dissolved and/or dispersed in a polymer or an adhesive. Such patches are optionally constructed for continuous, pulsatile, or on demand delivery of pharmaceutical agents. Still further, transdermal delivery of the ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, is optionally accomplished by means of iontophoretic patches and the like. Additionally, transdermal patches provide controlled delivery of the ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof. The rate of absorption is optionally slowed by using rate-controlling membranes or by trapping the ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, within a polymer matrix or gel. Conversely, absorption enhancers are used to increase absorption. An absorption enhancer or carrier includes absorbable pharmaceutically acceptable solvents to assist passage through the skin. For example, transdermal devices are in the form of a bandage comprising a backing member, a reservoir containing the ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, optionally with carriers, optionally a rate controlling barrier to deliver the ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, to the skin of the host at a controlled and predetermined rate over a prolonged period of time, and means to secure the device to the skin.
Formulations that include a ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, suitable for intramuscular, intrathecal, subcutaneous, or intravenous injection include physiologically acceptable sterile aqueous or non-aqueous solutions, dispersions, suspensions or emulsions, and sterile powders for reconstitution into sterile injectable solutions or dispersions. Examples of suitable aqueous and non-aqueous carriers, diluents, solvents, or vehicles including water, ethanol, polyols (propyleneglycol, polyethylene-glycol, glycerol, cremophor and the like), suitable mixtures thereof, vegetable oils (such as olive oil) and injectable organic esters such as ethyl oleate. Proper fluidity is maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants. Formulations suitable for subcutaneous injection also contain optional additives such as preserving, wetting, emulsifying, and dispensing agents.
For intravenous injections, a ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, is optionally formulated in aqueous solutions, preferably in physiologically compatible buffers such as Hank's solution, Ringer's solution, or physiological saline buffer. For transmucosal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. For other parenteral injections including intrathecal and intramuscular injections, appropriate formulations include aqueous or nonaqueous solutions, preferably with physiologically compatible buffers or excipients.
Parenteral injections optionally involve bolus injection or continuous infusion. Formulations for injection are optionally presented in unit dosage form, e.g., in ampoules or in multi dose containers, with an added preservative. In some embodiments, the pharmaceutical composition described herein are in a form suitable for parenteral injection as a sterile suspensions, solutions or emulsions in oily or aqueous vehicles, and contain formulatory agents such as suspending, stabilizing and/or dispersing agents. Pharmaceutical formulations for parenteral administration include aqueous solutions of the ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, in water soluble form. Additionally, suspensions of the ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, are optionally prepared as appropriate oily injection suspensions.
In some embodiments, the ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, is administered topically and formulated into a variety of topically administrable compositions, such as solutions, suspensions, lotions, gels, pastes, medicated sticks, balms, creams or ointments. Such pharmaceutical compositions optionally contain solubilizers, stabilizers, tonicity enhancing agents, buffers and preservatives.
The ACTH peptide or fragment, analog, complex or aggregate thereof, or any combination thereof, is also optionally formulated in rectal compositions such as enemas, rectal gels, rectal foams, rectal aerosols, suppositories, jelly suppositories, or retention enemas, containing conventional suppository bases such as cocoa butter or other glycerides, as well as synthetic polymers such as polyvinylpyrrolidone, PEG, and the like. In suppository forms of the compositions, a low-melting wax such as, but not limited to, a mixture of fatty acid glycerides, optionally in combination with cocoa butter is first melted.
Male Sprague Dawley rats weighing 125-150 g are maintained on a 12 hr light: 12 hr dark cycle and supplied with rat chow and water ad lib. The animals are divided into 3 groups: (1) intact; (2) denervated controls which receive 0.2 ml saline IP 3 hr after crush denervation and thereafter every 48 hr until one day prior to the electromechanical recordings; (3) 3 h after crush denervation, treated with a first dose of 20 IU ACTHAR® gel, a subsequent dose of 20 IU ACTHAR® gel in the same week, 40 IU ACTHAR® gel twice a week and then every other month for three months.
Denervation procedure is carried out as described by Strand et al. in Peptides, 1988, 9, 215-221. Mechanical recordings and Motor Unit Performance are determined as described by Strand et al.
Significance of differences among groups is determined by means of analysis of variance. Significance between specific means is tested by the Student Newman-Keuls test. An improvement in Tetanic tension of EDL muscle is indicative of beneficial effect of a pulsed dosing regimen of ACTHAR® gel.
Transgenic mice carrying high copy numbers of the transgene with the G93A human SOD1 mutation are used in this study which is a modification of the study described by Feng et al., Neuroscience, 2008, 155, 567-572. All transgenic mice are genotyped by PCR amplification of DNA extracted from the tails to identify the SOD1 mutation.
Mice are divided into vehicle and treatment groups. ACTHAR® gel treatment is initiated 30 days after birth and continued until the end stage. Each animal is given a first dose followed by a subsequent weekly dose of ACTHAR® gel. All animals are maintained on a 12 hours light/dark cycle. Behavior tests are performed during the light period. Various tests are routinely performed starting from 12 weeks of age until death.
Rotarod performance test: Motor coordination is assessed by measuring the length of time for which mice remained on the rotating rod (16 r.p.m.). Three trials are given to each animal and the longest retention time is used as a measure of competence at the task. The evaluation scores are: grade 0, >180 s; grade 1, 60-180 s; grade 2, <60 s; grade 3, falling off the rod before rotation.
Postural reflex test: This is conducted essentially as described by Bederson et al., Stroke, 1986, 17, 472-476 to examine the strength of the forelimbs. The deficits are scored as follows: grade 0, no evidence of paralysis; grade 1, forelimb flexion upon tail suspension; grade 2, decreased resistance to lateral push (and forelimb flexion) without circling; grade 3, same as grade 2 but with circling; grade 4, unable to walk but maintaining upright body position; grade 5, complete paralysis.
Screen test: This test serves as an indicator of general muscle strength. The animal is placed on a horizontally positioned screen with grids. The screen is then rotated to the vertical position. The deficit scores are: grade 0, grasping the screen with forepaws for more than 5 s; grade 1, temporarily holding the screen without falling off; grade 2, same as grade 1 but falling off within 5 s; grade 3, falling off instantaneously.
An improvement or stabilization in any of the above scores is indicative of a therapeutic effect of ACTHAR® gel.
G93A SOD1 (G1H, high copy) transgenic mice—16 control animals and 56 treated animals—were included in this study. Control animals were injected with 5% gelatin. Test animals were divided into groups of 5-9 animals where each group was injected intramuscularly or subcutaneously with ACTHAR® gel as follows and as shown below in Table 1: IM 120 U/kg 2 day interval (i.e., every other day); SC 120 U/kg 2 day interval (i.e., every other day); SC 60 U/kg 2 day interval (i.e., every other day); SC 60 U/kg 7 day interval.
All animals were maintained on a 12 hours light/dark cycle. Behavior tests were performed during the light period. Various tests for tremor and paralysis were routinely performed starting from injections of ACTHAR® gel until death.
