Description

GASTRO-RESISTANT CONTROLLED RELEASE ORAL DOSAGE FORMS

[0001] Intentionally left blank. FIELD OF THE DISCLOSURE

[0002] The present disclosure relates generally to oral gastro-resistant (GR) controlled release (CR) dosage forms that reduce the risk of QT prolongation in patients treated with the compound identified as 1H-Isoindol-1-one, 2-[[1-[2-(4-Fluorophenyl)-2-oxoethyl]-4-piperidinyl]methyl]- 2,3-dihydro-, hydrochloride, hydrate (1:1:2), and to the use of these dosage forms for treating schizophrenia and other diseases. BACKGROUND

[0003] The QT interval is a measurement of the duration of ventricular de- and repolarization. Prolongation of the QT interval, referred to as QT prolongation, can result in increased risk for ventricular arrhythmias, including torsades de pointes (TdP). Since a number of drugs have been shown to induce QT prolongation, development of new drugs typically includes assessment of their QT prolongation potential.

[0004] An investigational medicine, roluperidone hydrochloride, with the code name MIN-101 is being developed by Minerva Neurosciences, Inc. (Waltham, MA) for treating negative symptoms in schizophrenia patients. The active ingredient in MIN-101 (previously known as CYR-101 and MT-210) has the chemical name 1H-Isoindol-1-one, 2-[[1-[2-(4-Fluorophenyl)-2- oxoethyl]-4-piperidinyl]methyl]-2,3-dihydro-, hydrochloride, hydrate (1:1:2). Formula I below shows the structure of the free base (Compound (I)): [Image disponible dans le document PDF, Image available in the PDF document] (I).

[0005] As disclosed in US Patent No. 9,458,130, QT prolongation in patients treated with MIN- 101 has been observed and appears to be related to plasma levels of Compound (I) and more specifically to a metabolite identified as BFB-520. The '130 patent discloses that QT prolongation induced by administration of MIN-101 can be reduced by administering this agent in a modified release (MR) formulation that provides a maximum plasma concentration (C<com:Sub>max< / com:Sub>) of Compound (I) and BFB-520 below 80 ng / mL and 12 ng / mL, respectively. However, a need exists for a formulation that further reduces the potential for QT prolongation after oral administration of MIN-101 in either a fasted state or a fed state, while maintaining a therapeutically effective level of Compound (I) throughout a dosing interval. SUMMARY

[00180] The present disclosure relates to novel gastro-resistant CR oral dosage forms comprising Compound (I) or a pharmaceutically acceptable salt and / or solvate thereof, bulk compositions and processes for manufacturing the dosage forms, and use of the dosage forms for therapeutic treatment of patients suffering from various disorders and conditions.

[00181] In one embodiment, the present disclosure relates to novel gastro-resistant CR oral dosage forms comprising Compound (I), or a pharmaceutically acceptable salt and / or solvate thereof, wherein upon oral administration to a subject, the C<com:Sub>max< / com:Sub> of Compound (I) and its metabolite, BFB-520, are reduced while the AUC<com:Sub>(0-tau)< / com:Sub> is maintained compared to previously disclosed formulations and / or dosage forms, e.g., those as disclosed in US Patent No. 9,458,130.

[00182] In one embodiment, the present disclosure relates to novel gastro-resistant CR oral dosage forms comprising Compound (I), or a pharmaceutically acceptable salt and / or solvate thereof, wherein upon oral administration to a subject, similar AUC-based exposure of Compound (I) is maintained compared to a previous study with previously disclosed formulations and / or dosage forms, e.g., those as disclosed in US Patent No. 9,458,130, which achieved its primary endpoint of improving negative symptoms in patients with schizophrenia with both doses tested, 64 mg and 32 mg.

[00183] In one embodiment, the present disclosure relates to novel gastro-resistant CR oral dosage forms comprising Compound (I) or a pharmaceutically acceptable salt and / or solvate thereof, wherein upon oral administration to a subject, the <com:Math><semantics>t1 / 2<annotation encoding="application / x-tex">t_{1 / 2}< / annotation>< / semantics>< / com:Math> of Compound (I) is prolonged compared to previously disclosed formulations and / or dosage forms, e.g., those as disclosed in US Patent No. 9,458,130.

[00184] In one embodiment, the present disclosure relates to novel gastro-resistant CR oral dosage forms comprising Compound (I) or a pharmaceutically acceptable salt and / or solvate thereof, wherein upon oral administration to a subject, the <com:Math><semantics>Cmax<annotation encoding="application / x-tex">C_{max}< / annotation>< / semantics>< / com:Math> of BFB-520 in the subject's plasma is reduced to promote drug safety.

[00185] In one embodiment, the present disclosure relates to novel gastro-resistant CR oral dosage forms comprising Compound (I) or a pharmaceutically acceptable salt and / or solvate thereof, wherein upon oral administration to a subject, the <com:Math><semantics>Cmax<annotation encoding="application / x-tex">C_{max}< / annotation>< / semantics>< / com:Math> of BFB-520 is reduced by about 30% or more (e.g., 30%, 35%, or 40%) compared to previously disclosed formulations and / or dosage forms, e.g., those as disclosed in US Patent No. 9,458,130.

[00186] In one embodiment, the reduction of the <com:Math><semantics>Cmax<annotation encoding="application / x-tex">C_{max}< / annotation>< / semantics>< / com:Math> of BFB-520 in the subject leads to a reduction in the potential for transient QTc increases observed in a previous study at the higher dose but not at the lower dose. In one example, administration of novel gastro-resistant CR oral dosage forms described herein comprising Compound (I), or a pharmaceutically acceptable salt and / or solvate thereof, does not result in an observable QTc prolongations.

[00187] In one embodiment, the present disclosure relates to novel gastro-resistant CR oral dosage forms comprising Compound (I) or a pharmaceutically acceptable salt and / or solvate thereof, wherein the administration of the dosage form does not result in an observable food effect, i.e., the administration of the dosage form may occur with or without food without changing its pharmacokinetic properties.

[00188] In one embodiment, the present disclosure relates to novel gastro-resistant CR oral dosage forms comprising Compound (I) or a pharmaceutically acceptable salt and / or solvate thereof, wherein the dosage forms comprising Compound (I) retain previously established overall safety and tolerability profiles.

[00189] The novel gastro-resistant CR oral dosage forms disclosed herein allow for the delivery of Compound (I) to a lower part of the gastrointestinal tract, which unexpectedly reduced the highest concentration of BFB-520. This unexpected pharmacokinetic effect resulted in no observable QTc prolongations in the subjects who were administered these novel gastro- resistant CR oral dosage forms. Definitions and Abbreviations

[00190] The terms used herein have their ordinary meaning and the meaning of such terms is independent at each occurrence thereof. Notwithstanding the foregoing, and except where stated otherwise, the following definitions apply throughout the specification and claims.

[00252] An object of the present disclosure is to provide a gastro-resistant, controlled release oral dosage form comprising between about 4 mg to about 100 mg of Compound (I) or an equivalent amount of a pharmaceutically acceptable salt and / or solvate of Compound (I). The dosage form is formulated to exhibit, upon oral administration to a subject, a specific, desired release profile for Compound (I) which reduces the maximum plasma concentrations of BFB- 520 while providing a therapeutically effective amount of Compound (I) during one or more dosing intervals. This desired release profile is achieved in two ways: (a) delay release of Compound (I) until after gastric emptying pushes the dosage form to the small intestine and then (b) provide sustained release of at least about 90%, 95% or 100% of the amount of Compound (I) in the dosage form at a rate that provides a plasma PK profile which comprises a T<com:Sub>max< / com:Sub> for Compound (I) of between about 4 and about 22 hours.

[00253] This in vivo release profile for Compound (I) is designed to reduce the subject's plasma levels of BFB-520 below a threshold that is correlated with a greater risk for QT prolongation. In an embodiment, the threshold is a C<com:Sub>max< / com:Sub> for BFB-520 that is below 5.0 ng / mL, below 4.5 ng / mL, below 4.0 ng / mL, below 3.5 ng / mL, below 3.0 ng / mL, below 2.5 ng / mL, below 2.0 ng / mL, below 1.5 ng / mL, below 1.0 ng / mL, or below 0.5 ng / mL.

[00254] In some embodiments, the plasma PK profile for Compound (I) is further characterized in terms of one or more additional PK parameters, such as C<com:Sub>max< / com:Sub>, AUC<com:Sub>(0-tau)< / com:Sub>, C<com:Sub>min< / com:Sub> and other PK parameters defined above. It will be understood by the skilled person that the values for some of these additional PK parameters will depend, at least in part, on the amount of Compound (I) in the dosage form.

[00255] The values for the <com:Math><semantics>Tmax<annotation encoding="application / x-tex">T_{max}< / annotation>< / semantics>< / com:Math> and other plasma PK parameters produced by a dosage form described herein may exhibit some inter-individual variation within a population of subjects. Thus, in some embodiments, certain plasma PK parameters are expressed as mean values determined for a population of at least 2, 4, 8, 16 or more subjects. In an embodiment, the population consists of healthy volunteers. In an embodiment, each subject in the population has a positive test for an EM genotype. In an embodiment, each subject in the population has a positive test for an EM genotype or an IM genotype. In an embodiment, each subject in the population has a positive test for an IM genotype or a PM genotype. In an embodiment, each subject in the population has a positive test for a PM genotype.

[00256] Compound (I) may be synthesized using standard synthetic methods and procedures for the preparation of organic molecules and functional group transformations and manipulations, including the use of protective groups, as can be obtained from the relevant scientific literature or from standard reference textbooks in the field. Although not limited to any one or several sources, recognized reference textbooks of organic synthesis include: Smith, M.B.; March, J. March's Advanced Organic Chemistry: Reactions, Mechanisms, and Structure, 5<com:Sup>th< / com:Sup> ed.; John Wiley & Sons: New York, 2001; and Greene, T.W.; Wuts, P.G. M. Protective Groups in Organic Synthesis, 3<com:Sup>rd< / com:Sup>; John Wiley & Sons: New York, 1999. A method for preparing Compound (I) is described in U.S. Patent No. 7,166,617.

[00257] In an embodiment, the drug substance form of Compound (I) used in the dosage form is a dihydrate of a hydrochloride salt of Compound (I), which has the chemical name 1H- Isoindol-1-one, 2-[[1-[2-(4-Fluorophenyl)-2-oxoethyl]-4-piperidinyl]methyl]-2,3-dihydro-, hydrochloride, hydrate (1:1:2), which has a molecular formula of C<com:Sub>22< / com:Sub>H<com:Sub>23< / com:Sub>FN<com:Sub>2< / com:Sub>O<com:Sub>2< / com:Sub>, HCl, 2H<com:Sub>2< / com:Sub>O and a molecular weight of 438.92. Methods for preparing this Compound (I) drug substance are described in US Patent Nos 7,166,617 and 9,458,130. An amount of this drug substance that is equivalent to a specified amount of free base may be calculated by multiplying the specified amount of Compound (I) by 1.2; thus, 38.4 mg of this drug substance is equivalent to 32.0 mg of Compound (I).

[00258] In an embodiment, the delayed and sustained-release properties of the CR oral dosage form may be provided by encasing a sustained-release composition comprising the desired amount of Compound (I), or a pharmaceutically acceptable salt and / or solvate thereof, within an enteric coating.

[00259] Various physical and chemical approaches for designing sustained-release compositions are well known in the art. Any sustained-release composition that is capable of releasing Compound (I) to provide the in vivo plasma PK profile described herein may be used to prepare a dosage form of the disclosure. In an embodiment, the sustained-release composition comprises at least one polymeric material that modulates release of Compound (I).

In one embodiment, the polymeric material is a hydroxyproplymethocellulose.

[00260] In an embodiment, a mixture of a low viscosity and a high viscosity hypromellose is used as the controlled release agent in the sustained-release composition. The viscosity properties of suitable hypromelloses may be determined in a 2% by weight solution in water at 20°C as described in USP Hypromellose Monograph, Official December 1, 2016, which is available at http: / / www.usp.org / usp-nf / official-text / stage-6 / hypromellose-2015-11-20.

[00261] The enteric coating, which typically comprises a pH-sensitive polymer, begins to dissolve in an aqueous solution at pH greater than 5.5, and in one embodiment, begins to dissolve in an aqueous solution at pH greater than 6.0. In one embodiment, the pH-sensitive polymer begins to dissolve in an aqueous solution at pH greater than 6.5. In one embodiment, the pH-sensitive polymer begins to dissolve in an aqueous solution at pH 6.7. In an embodiment, the amounts of Compound (I) released in the stomach from a gastro-resistant CR dosage form administered to subjects in a fed state or a fasted state are about the same (e.g., less than 5%, less than 2% or less than 1% difference).

[00262] The composition and thickness of the enteric coating are typically chosen to substantially maintain its integrity in the stomach, while allowing substantially all of the enteric coating to dissolve after the dosage form leaves the stomach. In an embodiment, substantially all of the enteric coating dissolves within 15 minutes, 30 minutes, 1 hour or 2 hours after the dosage form leaves the stomach.

[00263] The design and preparation of gastro-resistant enteric coatings are well-known in the formulation art. Polyacids having an appropriate pKa range may be used to prepare enteric coatings. Non-limiting examples of suitable enteric coating materials are polymerized gelatin, shellac, methacrylic acid copolymer type C NF, cellulose butyrate phthalate, cellulose hydrogen phthalate, cellulose proprionate phthalate, polyvinyl acetate phthalate (PVAP), cellulose acetate phthalate (CAP), cellulose acetate trimellitate (CAT), hydroxypropyl methylcellulose phthalate, hydroxypropyl methylcellulose acetate, dioxypropyl methylcellulose succinate, carboxymethyl ethylcellulose (CMEC), hydroxypropyl methylcellulose acetate succinate (HPMCAS), and acrylic acid polymers and copolymers, typically formed from methyl acrylate, ethyl acrylate, methyl methacrylate and / or ethyl methacrylate with copolymers of acrylic and methacrylic acid esters. For example, the enteric coating may comprise a copolymer based on methacrylic acid and ethyl acrylate marketed as EUDRAGIT® L 30 D-55 by Evonik Industries AG. In an embodiment, the coating comprises a mixture of (i) EUDRAGIT® L 30 D-55 at 4.5 % to 5.0 %, w / w, or about 4.7% w / w and (ii) PlasACRYL<com:Sup>TM< / com:Sup> HTP20 at 0.80 % w / w.

[00264] In another aspect, the disclosure provides a batch composition and process for manufacturing a gastro-resistant CR oral dosage form described herein.

In an embodiment, the cumulative dissolution amount and dissolution rate at each time point in substantially similar profiles are within + / - 10% of the values for the corresponding time point in the target, CR-GR-01 or CR-GR-02 dissolution profiles shown in Tables 6 and 7.

[00268] B. Detection of Compound (I) and BFB-520 in Human Plasma

[00269] To assess whether a gastro-resistant CR oral dosage form comprising Compound (I) produces the desired PK profile for one or both of Compound (I) and BFB-520, plasma concentrations of the compound(s) of interest may be determined at various time points after administration of the dosage form to a single subject, but is typically determined in a group of two or more subjects. In an embodiment, PK profile is determined in a group of at least 8, 12, 16 or 20 subjects. In an embodiment, the group comprises healthy male and female subjects. In an embodiment, the number of subjects in the group is chosen to allow a statistically significant assessment of whether the PK profile produced by a test oral dosage form is a bioequivalent PK profile with respect to the PK profile shown in Figure 1.

[00270] An open-label, randomized, 3-treatment sequence, 3-period study to evaluate the PK profile of Compound (I) and its metabolite BFB-520 after single oral administration of 3 formulations of MIN-101 (2 prototypes of CR gastro-resistant (GR) formulations (GR-01 and GR-02) and 1 comparator MR formulation (MR32)) is summarized in Scheme 1 (MIN-101) and Scheme 2 (BFB-520).

[00282] BFB-520 is believed to be metabolized in part by CYP2D6. In clinical studies of MIN-101, CYP2D6 poor metabolizers have exhibited high plasma levels of BFB-520. Thus, in an embodiment, the C<com:Sub>max< / com:Sub> for BFB-520 is assessed after oral administration of a test dosage form comprising Compound (I) to only subjects who have been assigned an IM CYP2D6 genotype or an EM CYP2D6 genotype using a commercially available genotype test. In an embodiment, all of the subjects have been assigned an EM CYP2D6 genotype.

[00283] Levels of Compound (I) and the metabolite BFB-520 produced in plasma after oral administration of an oral dosage form of the disclosure may be determined by the method described below. It is expected that variations of and improvements to this method could be employed as well.

[00284] Blood samples from subjects are collected on sodium heparin tubes at various time points of interest. A suitable sampling schedule includes the following: Day 1 (D1): at pre-dose; 1h; 2h; 3h; 4h; 6h; 8h; 10h; 12h and 16h; Day 2 to Day 6 (D2-D6): at pre-dose Day 7 (D7): at pre-dose; 1h; 2h; 3h; 4h; 6h; 8h; 10h; 12h; 16; 24h (D8) and 48h (D9).

[00285] After blood centrifugation, a desired number of aliquots (typically 2) of each plasma sample are prepared in suitable storage containers (e.g., polypropylene tubes tightly capped to prevent leak and desiccation which could occur during storage). The containers containing the plasma samples are stored at -80°C for up to one month before analysis.

[00286] A GLP validated method to detect and quantify Compound (I) and its metabolites BFB-520 and BFB-999 employs liquid chromatographic (LC) analysis coupled to a mass spectrometry detection (MS / MS) after a liquid / liquid extraction step of Compound (I) and metabolites BFB-520 and BFB-999 from plasma samples.

[00287] The analytical method uses two internal standards (a deuterated analog of MIN-101 (designated herein as [<com:Sup>2< / com:Sup>H<com:Sub>6< / com:Sub>]-MIN-101 or MIN-101-d6 or CYR-101-d6) and BFB-784 for both BFB-520 and BFB-999), which were submitted to the same analytical procedure as MIN-101, BFB-520 and BFB-999 in plasma samples. MIN-101-d6 and BFB-784 have the structures shown in Formulas IV and V below: [Image disponible dans le document PDF, Image available in the PDF document] [Image disponible dans le document PDF, Image available in the PDF document] .. (IV) (V).

[00288] Chromatograms are processed by default in an automatic mode. Chromatographic peaks of MIN-101, BFB-520, BFB-999 and internal standards (IS) are identified according to their retention times. The recorded response is expressed as an area ratio of MIN-101 to MIN-101-d6, and of BFB-520 or BFB-999 to BFB-784.

[00289] The lower limit of quantification (LLOQ) of this analytical method in plasma is 0.25 ng / mL for MIN-101 and its metabolites BFB-520 and BFB-999.

[00290] Details of the analytical method are described in Example 7 below. It is expected that variations of and improvements to this analytical method could be employed as well. Treatment Methods

[00291] The gastro-resistant CR oral dosage forms of the present disclosure may be useful for treating diseases or conditions that are susceptible to treatment with Compound (I). As not limiting examples, it is believed that Compound (I) can potentially be used to treat schizophrenic and non-schizophrenic patients with one or more of the following symptoms or conditions: negative symptoms, depressive symptoms, sleep disorders and cognitive impairment.

[00292] In a phase 2b study, MIN-101 at 32 mg and 64 mg doses, demonstrated rapid, statistically significant and clinically meaningful reductions in negative symptoms in patients with schizophrenia. The oral dosage forms used in this Phase 2b study were the 32 mg MR tablet described in Example 1 below and an essentially identical 64 mg MR tablet. Neither of these MR tablets had a GR coating and each produced in vitro dissolution and plasma PK profiles that are different than those produced by the gastro-resistant CR oral dosage forms of the present disclosure.

[00293] Negative symptoms generally refer to a reduction in normal functioning, and include five major sub-domains: blunted affect (affective flattening, blunted expression), alogia (poverty of speech), amotivation (loss of volition), anhedonia (reduced ability to experience or anticipate pleasure) and asociality (social withdrawal). While negative symptoms are a well- documented and intensively studied aspect of schizophrenia, this class of symptoms has been identified in patients with other psychiatric and neurological disorders, including, for example, Alzheimer's disease and other dementias, particularly frontotemporal dementia (FTD), autism spectrum disorder (ASD), bipolar disorder (BPD), major depressive disorder (MDD), Parkinson's disease, temporal lobe epilepsy, stroke, and traumatic brain injury (TBI) (see, e.g., Boone et al, J. of Internat. Neuropsycol. Soc., 2003, Vol 9, pages 698-709; Bastiaansen, J. et al., J. Autism Dev. Disord. 2011, Vol 41:1256-1266; Getz, K. et al., Am. J. Psychiatry 2002, Vol 159:644-651; Winograd-Gurvich, C. et al., Brain Res. Bulletin, 2006, Vol. 70:312-321; Galynker et al., Neuropsychiatry Neuropsychol Behav Neurol 2000, Vol 13:171-176; Galynker I, et al., J. Nerv. Ment. Dis 1997, Vol 185:616-621; Chaudhury, S., et al., Indian J. of Neurotrauma 2005, Vol 2:13-21; Ameen, S et al., German J. of Psychiatry 2007). Indeed, as early as 2001, it was proposed that negative symptoms are common to mental illnesses generally (Herbener and Harrow, Schizophrenia Bulletin 2001, Vol. 27:527-537). Furthermore, reports of several population studies have concluded that between 20-22% of the general population have one or more negative symptoms, and that the majority of subjects with negative symptoms do not exhibit a clinical diagnosed psychiatric disorder (Werbeloff, N. et al., PLoS ONE 2015, Vol 10:e0119852; Barrantes-Vidal, N., et al., Schizophr. Res. 2010, Vol 122:219-225).

[00294] Thus, it is an object of the present disclosure to treat at least one negative symptom in a subject by a method of administering to the subject a gastro-resistant CR dosage form described herein one time per day (QD). In an embodiment, the subject is diagnosed with schizophrenia. In another embodiment, the subject does not have a clinical diagnosis of schizophrenia, i.e., is a non-schizophrenic patient.

[00295] For purposes of the disclosure encompassed herein, the term "negative" symptoms" is to be understood as including primary negative symptoms typically associated with schizophrenia, the negative symptoms measured in the PANSS negative symptoms subscale score, the negative factor score based on the pentagonal structure model method, and the negative symptoms measured in the BNSS.

[00296] In an embodiment, the negative symptom is one of the five major sub-domains of negative symptoms: blunted affect, alogia, amotivation, anhedonia and asociality. The core characteristics of each sub-domain are described below.

[00297] Blunted affect (affective flattening, blunted expression) is characterized by reduced intensity and range of emotional expression as manifested via vocal and non-verbal modes of communication including intonation (prosody), facial expression, hand-gestures and body movements.

[00298] Alogia (poverty of speech) is characterized by decreased quantity of speech, reduced spontaneous speech and loss of conversational fluency.

[00299] Amotivation (loss of volition) is characterized by deficits in the initiation and maintenance of goal-directed behaviors like work, study, sport, personal hygiene and daily tasks, especially when requiring and effort (cognitive or physical) and significant organization, as well as deficits in desire to undertake such activities. This sub-domain is related to apathy and lack of energy.

[00300] Anhedonia (reduced ability to experience or anticipate pleasure) is characterized by the looking forward to a reward, recreational or other pleasurable experience ("wanting") being more markedly and consistently impaired (anticipatory anhedonia) than the appreciation ("liking") of the experience itself (consummatory anhedonia).

[00301] Asociality (social withdrawal) is characterized by diminished interest in, motivation for, and appreciation of social interactions with others, like family and friends, loss of interest in intimate (sexual) relationships independent of any somatic problems, and for a child, may include loss of interest in playing with other children.

[00302] In some embodiments, the dosage form is administered to the subject once a day for a first treatment period of sufficient length to achieve improvement in at least one negative symptom. In an embodiment, the first treatment period is at least 2 weeks, at least 4 weeks, at least 6 weeks, at least 8 weeks, at least 10 weeks or at least 12 weeks. In an embodiment, positive symptoms in a subject treated with the dosage form are stable during the treatment period, i.e., remain at substantially the same level as at baseline. In an embodiment, the level of improvement in negative symptoms is a reduction of at least 3 points on the PANSS five factor (pentagonal structure model) negative symptom factor scores after 12 weeks of treatment. In an embodiment, the subject's negative symptom score continues to improve from 12 weeks to at least about 24, 36 or 48 weeks of treatment. The PANSS pentagonal structure model is described in WHITE L, HARVEY PD, OPLER L, LINDENMAYER J. EMPIRICAL ASSESSMENT OF THE FACTORIAL STRUCTURE OF CLINICAL SYMPTOMS IN SCHIZOPHRENIA. PSYCHOPATHOLOGY. 1997;30(5):263-74.

[00303] In some embodiments, if a subject experiences improvement in at least one negative symptom during the first treatment period, then administration of the therapeutically effective dose of Compound (I) is continued for a second treatment period of at least 12 weeks, at least 24 weeks, at least 48 weeks, or until the subject is determined to exhibit functional improvement subsequent to improvement in the negative symptoms. In an embodiment, positive symptoms in a subject treated with the dosage form are stable during at least part of the second treatment period, i.e., remain at substantially the same level as at baseline.

[00304] In some embodiments, the subject has a diagnosis of schizophrenia. In an embodiment, a subject selected for treatment with an oral dosage form of the disclosure has a base-line PANSS negative sub-score greater than or equal to 20. In an embodiment, the selected subject also has baseline scores of less than 4 on the following PANSS items: excitement, hyperactivity, hostility, suspiciousness, uncooperativeness and poor impulse control. In an embodiment, the selected schizophrenic subject has exhibited stable positive symptoms of schizophrenia for at least the previous one, two or three months and has exhibited negative symptoms for at least the previous one, two or three months.

[00305] In some embodiments, the schizophrenic subject treated with a gastro-resistant, CR oral dosage form of the present disclosure has prominent negative symptoms. In an embodiment, a schizophrenic subject is defined as having prominent negative symptoms when the subject has having a score <com:Math><semantics>≥4<annotation encoding="application / x-tex">\geq 4< / annotation>< / semantics>< / com:Math> (moderate) on at least three subscale items in the PANSS negative symptoms subscale items but not on PANSS positive subscale items. In an embodiment, the subject has both prominent positive and prominent negative symptoms when the subject has scores <com:Math><semantics>≥<annotation encoding="application / x-tex">\geq< / annotation>< / semantics>< / com:Math>4 on items for both positive and negative symptom items.

[00306] Up to 75% of schizophrenic patients suffer from cognitive impairment, and the phase 2b study of MIN-101 discussed above showed improvement in cognitive function. Thus, in an aspect, administration of a gastro-resistant CR oral dosage form of the present disclosure to a patient with a diagnosis of schizophrenia is intended to improve cognitive function in the patient.

[00307] In some embodiments, the subject has not been previously treated with an anti- psychotic drug. In other embodiments, the subject has discontinued prior treatment with an anti- psychotic drug due to experiencing one or more of the following: satisfactory reduction in positive symptoms, an inadequate response for negative symptoms, or intolerable side effects.

[00308] A secondary outcome of the phase 2b study of MIN-101 discussed above was patients' performance on the Calgary Depression Scale for Schizophrenia (CDSS) ADDINGTON D, ADDINGTON J, MATICKA-TYNDALE E. ASSESSING DEPRESSION IN SCHIZOPHRENIA: THE CALGARY DEPRESSION SCALE. BRITISH JOURNAL OF PSYCHIATRY SUPPLEMENT 1993; (22):39-44. The CDSS has little overlap with positive and negative symptoms and has become the recommended scale to assess the severity of depression in patients with schizophrenia. In the phase 2b study, the severity of symptoms as measured by the CDSS was reduced following treatment with 32 or 64 mg of MIN-101 compared to placebo. A correlation analysis between baseline treatment effects on negative symptoms and on depression symptoms in this patient cohort demonstrated there was only a small correlation between MIN-101's effects on these two symptom categories. Thus, since the effects of MIN-101 on negative symptoms and depression symptoms in schizophrenia patients were largely independent of each other, MIN-101 has the potential to alleviate one or more depression symptoms in patients who are not schizophrenic.

[00309] Thus, another object of the present disclosure is to treat at least one symptom of depression in a subject in need thereof by a method of administering a gastro-resistant CR dosage form described herein. In an embodiment, the subject has a diagnosis of schizophrenia. In an embodiment, the improvement in depression symptoms in a schizophrenic patient is measured using the CDSS.

[00310] It is another object of the present disclosure to reduce the risk for QT prolongation in a subject treated with Compound (I) by administering to the subject Compound (I) as formulated in a gastro-resistant CR dosage form described herein. In an embodiment, the subject has been identified as having one or more risk factors for drug-induced QT prolongation. In an embodiment, the subject discontinued previous treatment with a compound other than Compound (I) due to experiencing QT prolongation. In an embodiment, the subject discontinued previous treatment with a different dosage form comprising Compound (I) due to experiencing QT prolongation. In an embodiment, the subject has a diagnosis selected from the group consisting of: prominent negative symptoms of schizophrenia, prominent positive and prominent negative symptoms of schizophrenia, major depressive disorder (MDD), a sleep disorder and cognitive impairment.

[00311] In some embodiments of any of the above treatment methods, the gastro-resistant oral dosage form is administered in the morning or evening. In an embodiment, the dosage form is administered at least two hours before eating.

[00312] In some embodiments of any of the above treatment methods, the subject is 12 or more years of age. In some embodiments, the subject is at least 14, 16, 18, or 20 years old. In some embodiments, the subject is less than 50, 45, 40, 35 or 30 years old. In an embodiment, the subject is at least 16 years old and less than any of 40, 35 or 30 years old.

[00313] In some embodiments of any of the above treatment methods, the dosage form may be administered to the subject in combination with another therapeutic agent. In an embodiment, the other therapeutic agent does not inhibit CYP2D6 activity. In an embodiment, the subject is diagnosed with schizophrenia and the other therapeutic agent is an anti-psychotic drug.

[00314] In some embodiments of any of the above treatment methods, the subject may have been assigned an IM genotype or and EM genotype. In an embodiment, the subject has been assigned an EM genotype.

[00315] In some embodiments of any of the above treatment methods, the oral dosage form may comprise 32 mg of Compound (I). In an embodiment, the oral dosage form consists essentially of the components listed in Table 2 or Table 3 below. EXAMPLES Example 1: Description of a 32 mg MR tablet used in the Phase 2b Trial of MIN-101.

[00316] The MR 32 mg tablets are supplied as round (diameter 10 mm and R=10) white- coated tablets free from visual defects. Each tablet contains 32 mg of Compound (I). The complete statement of the components and quantitative composition of MR 32mg tablet is given in Table 1 below.

[00317] The CR GR-01 tablets are supplied as round (diameter 10 mm and R=10) tablets, free from visual defects. Each tablet contains 32 mg of Compound (I). The complete statement of the components and quantitative composition of CR GR-01 tablet is given in Table 2.

[00318] The CR GR-02 tablets are supplied as round (diameter 10 mm and R=10) tablets, free from visual defects. Each tablet contains 32 mg of Compound (I). The complete statement of the components and quantitative composition of CR GR-02 tablet is given in Table 3 below.

Batch Formula for CR GR-01 and CR GR-02 tablets.

[00319] A representative batch size for the CR GR-01 and CR GR-02 tablets are 5,400 tablets. The batch formulas are described in Tables 4 and 5 below. Table 4: Batch Formula for CR GR-01 tablet [Image disponible dans le document PDF, Image available in the PDF document] NA: Not Applicable Table 5: Batch Formula for CR GR-02 tablet [Image disponible dans le document PDF, Image available in the PDF document] Table 5A: Batch Formula for GR-01 / B Tablets (representative batch formula size is 150 000 tablets [Image disponible dans le document PDF, Image available in the PDF document] [Image disponible dans le document PDF, Image available in the PDF document] Example 5: Development of an Optimized In Vitro Dissolution Method

[00320] Based on Compound (I) PK profiles obtained with MIN-101 MR 32mg tablets used in clinical studies, an in vitro / in vivo correlation (IVIVC) approach was proposed. The IVIVC approach is defined by the FDA as a predictive mathematical model describing the relationship between an in-vitro property of the dosage form and an in-vivo response. In this context, the model refers to the relationship between the in vitro dissolution of the MR 32mg tablet and its in vivo response such as Compound (I) plasma concentration. The main objectives of the IVIVC model were to validate the use of a predictive in-vitro dissolution method and to select target optimized formulations. If the validity of the IVIVC model is confirmed by clinical results, the in-vitro dissolution method could be used as a surrogate method for clinical studies.

[00321] First, after analysis of all PK data for Compound (I) from clinical studies, an in-vitro dissolution profile of the MR 32 mg tablet described in Example 1 was defined. This target in-vitro dissolution profile was then used to develop an optimized in-vitro dissolution method. This method is described in the next Example.

[00322] Secondly, and when the in-vitro dissolution method was considered as closed enough to the expectations, the target in-vitro dissolution profile of a gastro-resistant CR oral dosage form was defined and used to design the gastro-resistant dosage forms described in Examples 2 and 3. The dissolution profiles for these two GR dosage forms (GR-01 and GR-02) and the MR 32 mg tablet of Example 1, which were generated using the optimized dissolution method, are shown in tables 6 and 7 below. Table 6: Cumulative In Vitro Dissolution Profiles [Image disponible dans le document PDF, Image available in the PDF document] [Image disponible dans le document PDF, Image available in the PDF document] Table 7: In Vitro Dissolution Rate Profiles [Image disponible dans le document PDF, Image available in the PDF document] <com:Sup>1< / com:Sup>not considered

[00323] The CR GR-01 and CR GR-02 tablets and the MR 32 mg tablet, used as a comparator, were tested in a clinical study (MIN-101-C06) to evaluate the plasma PK profile of each dosage form.

Part 1: PK Evaluation Part 1 is an open-label, randomised, 3-treatment sequence, 3-period study to evaluate the PK profile of MIN-101 and its metabolites (BFB-520 and BFB-999) after single oral administration of 3 formulations of MIN-101 (2 prototypes of CR gastro-resistant (GR) formulations and 1 comparator MR formulation). Each subject will receive a single dose of each of the formulations over the 3 periods. There will be a washout of <com:Math><semantics>14±2<annotation encoding="application / x-tex">14 \pm 2< / annotation>< / semantics>< / com:Math> days between the three periods. In total, 16 healthy CYP2D6 EM male or female subjects (with an ideal equal gender split, but a minimum of 6 of each sex) will be dosed to ensure data in 12 evaluable subjects. To be evaluable, subjects must have received all 3 formulations and have sufficient data for the primary objective of Part 1 of the study. Subjects must provide written informed consent to participate in the study before evaluations are performed or any laboratory samples are collected. Subjects will be evaluated for study eligibility during the screening period. After written informed consent is obtained, a complete medical history will be documented. A complete physical examination will be conducted, including measurement of vital signs, ECG (triplicate), body weight, and height. Hematology, clinical chemistry and urinalysis will be performed for all subjects. All subjects must be willing to use an acceptable double-barrier method of birth control with their partners from Screening through 90 days after the last dose. Part 2: Food effect Subjects who completed part 1 of the study will return and receive a further single oral dose of one of the selected GR prototype under fed conditions to allow the assessment of food effect by comparison of the PK properties to those obtained in Part 1. Part 2 will commence after a review of the PK and safety data to decide which GR formulation will be used. There will be a wash-out period of <com:Math><semantics>14±2<annotation encoding="application / x-tex">14 \pm 2< / annotation>< / semantics>< / com:Math> days after part 1 has been completed. The end-of-study or early withdrawal assessments will be performed 5-9 days after the last received dose. Number of Subjects (planned): In total, 16 healthy CYP2D6 EM male or female subjects (with an ideal equal gender split, but a minimum of 6 of each sex) will be dosed to ensure data in 12 evaluable subjects. Subjects who are withdrawn for non-IMP related adverse events (AEs) will be replaced as required to ensure 12 evaluable subjects for Part 1 and for Part 2, at the end of the clinical study. Subjects withdrawn due to an IMP-related AE will not be replaced. Diagnosis and Main Criteria for Inclusion / Exclusion: Inclusion Criteria Subjects must satisfy all of the following inclusion criteria during screening to be enrolled in the study: 1.

[Image disponible dans le document PDF, Image available in the PDF document] EVALUATION CRITERIA Pharmacokinetics: Plasma will be stored at -80°C until analysis. Plasma samples will be analyzed for MIN-101 and its metabolites BFB-520 and BFB-999 using a validated LC-MS / MS method. Blood samples for MIN-101 will be collected at time 0 (pre-dose), 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 10, 12, 14, 16, 20, 24, 28, 32, 36, 48, 60, and 72 hours post-dose on Day 1 of all periods. The following key plasma PK parameters will be calculated using non-compartmental methods: C<com:Sub>max< / com:Sub>, T<com:Sub>max< / com:Sub>, <com:Math><semantics>Tlag<annotation encoding="application / x-tex">T_{lag}< / annotation>< / semantics>< / com:Math>, partial AUC (e.g., AUC<com:Sub>12< / com:Sub>, AUC<com:Sub>24< / com:Sub>), AUC<com:Sub>last< / com:Sub>, AUC<com:Math><semantics>∞<annotation encoding="application / x-tex">\infty< / annotation>< / semantics>< / com:Math>, and <com:Math><semantics>t1 / 2<annotation encoding="application / x-tex">t_{1 / 2}< / annotation>< / semantics>< / com:Math>. Additional PK parameters may be included if deemed appropriate. ECG to be detailed as there will be PK / PD assessment The effects on cardiovascular variables will be evaluated by means of descriptive statistics and frequency tabulations. These tables will include observed values and changes from Baseline values (the pre-dose ECG will be used as Baseline) to allow detection of clinically relevant changes in individuals. The ECG variables that will be analyzed are heart rate, PR interval, QRS interval, QT interval, and QTc interval corrected for heart rate using QTcF. QTcF values will be tabulated for their absolute values and also tabulated relative to Baseline measurements in order to detect individual QTcF changes. Descriptive statistics of QTcF intervals and changes from Baseline will be summarised at each scheduled time point. The percent of subjects with QTc interval > 450 milliseconds, > 480 milliseconds, or <com:Math><semantics>≥<annotation encoding="application / x-tex">\geq< / annotation>< / semantics>< / com:Math> 500 milliseconds will be summarised as will the percent of subjects with QTcF interval increases from Baseline of 30 to 59 milliseconds or <com:Math><semantics>≥<annotation encoding="application / x-tex">\geq< / annotation>< / semantics>< / com:Math> 60 milliseconds. Important abnormalities in ECG waveform that are changes from the Baseline readings will be reported (e.g., changes in T-wave morphology or the occurrence of U-waves). Safety and Tolerability: The incidence of adverse events and clinically significant abnormal laboratory, vital signs and ECGs values will be recorded based upon Investigator observation and subject reporting. STATISTICAL CONSIDERATIONS Sample size: The sample size for this study is based upon both quantitative and qualitative consideration. In previous single dose experience with EM subjects, the inter-subject coefficient of variance (CV) for plasma AUC and C<com:Sub>max< / com:Sub> for MIN-101 reference formulation is estimated to be about 30% and 50%, respectively. Therefore, the selected sample size of 12 to 16 completers should be sufficient to address the objectives of this study and to detect the occurrence of rare adverse events should such event are likely due to treatment with MIN-101. Every effort will be made to have an equal number of males and females enrolled. Pharmacokinetics: Pharmacokinetic parameters will be summarized by mean, standard deviation, standard error of the mean, coefficient of variation, minimum, median, and maximum, as appropriate, for each formulation and between the selected MR formulation for each food condition. The 90% confidence intervals for the ratio of mean log-transformed plasma partial AUC, AUC<com:Sub>last< / com:Sub>, and AUC<com:Sub>10< / com:Sub> and C<com:Sub>max< / com:Sub> will be constructed using the estimated least squares means and intra-subject variance from a mixed effects model. Additional analysis will be performed if deemed necessary including the relationship between plasma levels of MIN-101 and its main metabolites and changes in QTcF intervals. Safety: Safety and tolerability of MIN-117 will be based upon the review of individual values and summary statistics. Incidence of treatment-emergent adverse events will be tabulated by counts and percentages. Abnormalities in clinical laboratory, vital signs, and ECG will be based on pre-defined normal ranges and will be tabulated by dose group showing subject counts and percentages.
