Abstract
Description
Technical Field
[0001] This disclosure relates to pharmaceutical compositions for subcutaneous administration comprising olanzapine, an organic solvent, a triblock copolymer, and a diblock copolymer, and methods of using such compositions to treat mental illnesses and conditions that respond to olanzapine. Background Technology
[0002] Schizophrenia is a severely debilitating mental illness characterized by positive symptoms (such as delusions, hallucinations, and severe behavioral disturbances) and negative symptoms (such as emotional flattening, aphasia, and avoidance) (New York State Office of Mental Health, 2019; Stefan et al., 2002).
[0003] The global lifetime risk of developing this condition is approximately 1% across different geographical, cultural, and socioeconomic regions. Because the disease follows a chronic course and involves long-term, persistent damage in most patients, long-term treatment with antipsychotic medication is usually required.
[0004] Non-adherence and high discontinuation rates are particularly problematic in patients with schizophrenia. Premature discontinuation of antipsychotic medication is common; in the Clinical Antipsychotic Intervention Efficacy Trial (CATIE), 74% of patients discontinued medication within 18 months due to poor tolerability or inadequate efficacy, patient choice (i.e., non-compliance / withdrawal), or investigator-related reasons (Lieberman et al., 2005). Even among those who do not explicitly discontinue medication, non-adherence to long-term oral medication regimens remains one of the most significant treatment problems in schizophrenia and related conditions (Kane et al., 2013). Consequently, many of these patients do not experience the full benefits of antipsychotic medication and frequently relapse or worsen, requiring readmission (Carbon and Correll, 2014) and often experiencing psychotic emergencies (Rainer, 2008).
[0005] Therefore, the availability of long-acting injectable (LAI) antipsychotics may improve adherence in patients with schizophrenia (Barnes and Curson, 1994; Hughes, 2008; Keith and Kane, 2003; Kishimoto et al., 2021; Walburn et al., 2001), and has been shown in randomized trials, cohort studies, and mirror studies to significantly reduce relapse and rehospitalization compared to oral antipsychotics, and to significantly improve many clinically relevant outcomes.
[0006] Olanzapine is a well-characterized and commonly used atypical antipsychotic prescription drug approved for the treatment of schizophrenia, available in oral and intramuscular (IM) formulations. Olanzapine is currently marketed in the United States as ZYPREXA tablets (2.5, 5, 7.5, 10, 15, and 20 mg); ZYPREXA INTRAMUSCULAR for rapid-acting injection (10 mg / mL); and as... Orally disintegrating tablets (5, 10, 15, and 20 mg) (ZYPREXA, ZYPREXA-HYDIS, ZYPREXA INTRAMUSCULAR US Prescription Information [USPI] 2021). ZYPREXA It is an extended-release suspension of olanzapine dihydroxynaphthylpropionate powder and solution, administered via deep intramuscular injection into the gluteal muscle every 2 weeks (150, 210, and 300 mg) or every 4 weeks (300 and 405 mg), depending on the target oral olanzapine dose (10, 15, or 20 mg / day). ZYPREXA (ZYPREXA (PI, 2021) is currently approved and marketed in the United States for the treatment of schizophrenia; however, it is only available through a limited distribution process. It is another olanzapine dihydroxynaphthyl acid product, which is similar to ZYPREXA. They have the same composition.
[0007] ZYPREXA Administration must be performed in a registered medical facility with readily available emergency response services. After each treatment, healthcare professionals must monitor the patient continuously for at least 3 hours at the facility, ensuring the patient is conscious, disoriented, and free from any signs and symptoms of post-injection delirium / sedation syndrome (PDSS) (a possible consequence of the route of administration) before discharge. PDSS is characterized by severe sedation (which may include coma) and / or delirium following injection. In PDSS events, patients exhibit elevated plasma concentrations of olanzapine, suggesting that accidental partial intravascular injection or vascular injury during administration may induce accelerated salt dissolution, potentially contributing to the PDSS. See, for example, Heres S, Kraemer S, Bergstrom RF, and Detke HC, Pharmacokinetics of olanzapine long-acting injection: the clinical perspective, Int. Clin. Psychopharmacol. 2014.
[0008] All patients must remain vigilant for PDSS symptoms and be able to access emergency medical assistance at facilities capable of providing medical monitoring and resuscitation. This is due to the safe use of ZYPREXA. Extensive and inconvenient preventative measures are required, and this product is rarely used in routine clinical practice. Therefore, the available options for psychiatrists in the clinical management of schizophrenia are limited. Alternative treatment options are needed.

[0037] Figure 1 The X-ray diffraction (XRD) pattern of olanzapine crystal form II is shown.
[0038] Figure 2 The graph shows the mean (±SD) olanzapine plasma concentration versus time after a single subcutaneous injection of different compositions at a dose of 405 mg or after two repeated intramuscular administrations of ZYPADHERA products at a dose of 300 mg every 2 weeks.
[0039] Example 2 further describes this study. SD = Standard deviation.
[0040] Figure 3The graphs showing mean (+ / - SD) olanzapine plasma concentrations versus time, plotted on linear (upper) and semi-logarithmic (lower) scales by administration date, represent a safety analysis set of studies described in Example 5 following oral olanzapine concentrations at steady-state and washout periods. SD = standard deviation.
[0041] Figure 4 The mean (±SD) plasma olanzapine concentration (ng / mL) in healthy subjects, based on linear (upper) and semi-log (lower) scales, is shown in the study described in Example 5. SD = standard deviation.
[0042] Figure 5 The mean (±SD) plasma olanzapine concentrations (ng / mL) in patients following a single subcutaneous dose of formulation 1, based on linear (upper) and semi-logarithmic (lower) scales, are shown in the study described in Example 5. SD = standard deviation.
[0043] Figure 6 The graph shows the mean (± standard deviation) olanzapine plasma concentrations versus time on a linear scaling basis, plotted by cohort and administration date: multi-dose patient cohort after formulation 1 (safety analysis set). The horizontal line represents a clinically relevant olanzapine plasma concentration of 10 ng / mL.
[0044] Figure 7 The graph shows the mean (± standard deviation) olanzapine plasma concentrations versus time on a semi-logarithmic scale, plotted by cohort and administration date: multi-dose patient cohort after formulation 1 (safety analysis set). The horizontal line represents a clinically relevant olanzapine plasma concentration of 10 ng / mL.
[0045] Figure 8 The figures show the median pharmacokinetic characteristics and pharmacokinetic variability (5th and 95th percentiles) of olanzapine concentrations observed in the study described in Example 4 (left panel) and formulation 1 (right panel). The top panel shows cohort 8 (left panel: oral dose = 10 mg; right panel: formulation 1 dose = 283 mg). The bottom panel shows cohort 9 (left panel: oral dose = 20 mg; right panel: formulation 1 dose = 566 mg).
[0046] Figure 9A schematic diagram of the study described in Example 6 is shown. During the screening phase, patients who had not previously received oral olanzapine would receive two doses of oral olanzapine over two consecutive days (the second dose should be taken at least 24 hours before randomization) to assess patient tolerability (oral olanzapine 10 mg / day or higher [but not exceeding 20 mg / day], at the investigator's discretion). Patients who had received olanzapine within the past year would not need to receive two doses of oral treatment. The investigator would confirm prior use, tolerability, and duration of olanzapine treatment to ensure prior tolerability. To maintain blinding in Phase 1, all patients would be re-randomized between Phase 1 and Phase 2; patients previously assigned to the active treatment group would maintain their Phase 1 treatment group (the re-randomization of patients in the Formulation 1 group was only to maintain blinding in Phase 1 and was, in fact, a deterministic grouping, not a randomization), while patients previously assigned to the placebo group would be randomized to one of the active treatment groups in a 1:1:1 ratio. Treatment grouping on an individual patient basis would only be revealed in Phase 2 after the study procedures related to the assessment of the Phase 1 efficacy and safety endpoints were completed and reported. The unblinding of Phase 2 treatment allocations was conducted by the sponsor or representative during weeks 8 to 12 according to a pre-defined procedure in the relevant study plan, provided that all requirements specified in that procedure were met. Therefore, although the administration in week 8 was allocated to Phase 2, all parties were treated in a blinded manner, similar to the administration in Phase 1. q1m = once a month; R = randomization.

Examples of alkyl groups include methyl, ethyl, n-propyl, isopropyl, n-butyl, tert-butyl, isobutyl, sec-butyl, n-pentyl, n-hexyl, etc. When a range of carbon atoms is used herein, such as C1-C6, it includes all ranges and individual carbon atom numbers. For example, "C1-C3" includes C1-C3, C1-C2, C2-C3, C1, C2, and C3.
[0060] The term "patient" or "patient" is used throughout this specification to describe a person receiving treatment (including prophylactic treatment) with the compositions provided in this disclosure. As used herein, the term "patient" or "patient" also refers to a single human being, or, where the context permits, a group of humans. Thus, in some embodiments, a patient is an individual human being. In other embodiments, a patient is a group of humans.
[0061] As used herein, the terms “subject” or “test subject” refer to a person to whom the compositions of this disclosure are administered.
[0062] In one embodiment, “treatment” or “management” for any disease or condition refers to improving the disease or condition (e.g., preventing or reducing the development of the disease or at least one of its clinical symptoms). In another embodiment, “treatment” or “management” refers to improving at least one physical or psychological parameter that the subject may not be able to discern. In yet another embodiment, “treatment” or “management” refers to regulating the disease or condition, whether physically (e.g., stabilization of identifiable symptoms), physiologically (e.g., stabilization of physical parameters), or both. In yet another embodiment, “treatment” or “management” refers to delaying the onset of a disease or condition or its symptoms. In some embodiments, “treatment” or “management” includes maintenance treatment, i.e., treatment aimed at maintaining the improvement in a patient’s condition by reducing or eliminating adverse changes in the patient’s clinical symptoms or physical or psychological parameters.
[0063] The term “effective” used to describe treatment means a treatment that is effective (i.e., produces the expected results, including but not limited to achieving primary and / or secondary clinical endpoints).
[0064] "Post-injection delirium / sedation syndrome" or "PDSS" should be understood as those symptoms or combinations of symptoms and conditions as defined in "Detke, HC et al., BMC Psychiatry 2010, 10:43" (which is incorporated herein by reference), or as any person skilled in the art would understand the term. For example, delirium-related symptoms include disorientation, confusion, ataxia, and dysarthria. Sedation-related symptoms include somnolence, sedation, or other changes in level of consciousness.
[0065] Number-average molecular weight (Mn) is typically measured by gel permeation chromatography (GPC), usually using polystyrene standards. Polymers can also be characterized by weight-average molecular weight (Mw). This can also be measured by gel permeation chromatography (GPC), typically using polystyrene standards. The polydispersity index is defined as the ratio of Mw to Mn, and is typically greater than 1 and less than 2.
[0066] Alternatively, or as an alternative to defining polymers by number-average molecular weight, polymers can also be defined by their theoretical molecular weight. The term "theoretical molecular weight" refers to the molecular weight of a copolymer determined by calculating the sum of the molar amounts of the repeating units that make up the polymer. The theoretical molecular weight indicates the average length of the target polymer chain.
[0067] As used herein, the terms "once a month" or "q1m" or "once a month" mean once a month, and they are used interchangeably. In some implementations, "once a month" or "q1m" or "once a month" means once every 28 days ± 5 days, such as once every 23 days, once every 24 days, once every 25 days, once every 26 days, once every 27 days, once every 28 days, once every 29 days, once every 30 days, once every 31 days, once every 32 days, or once every 33 days.

[0377] In some embodiments of the kit disclosed herein, the particle size distribution of olanzapine in the kit is characterized by a D(90) of about 20 μm to about 37 μm, a particle size distribution characterized by a D(3,2) of about 5.5 μm to about 7.5 μm, or a tap density of about 0.35 g / mL to about 0.44 g / mL, or any combination thereof. Olanzapine having these characteristics is described in U.S. Provisional Application No. 63 / 301,202, filed January 20, 2022.
[0378] As used herein, the term “D(90)” indicates that 90% (by volume) of the particles have a diameter less than or equal to the value shown. For example, D(90) or d(90) of 25 μm indicates that 90% (by volume) of the particles have a diameter less than or equal to 25 μm. As used herein, the term “D(3,2)” refers to the mean surface moment (Sottellal mean diameter, SMD), which may be relevant in cases where surface area is important (e.g., dissolution), reflecting the amount of fine particles in the sample. Particle size is typically determined by laser diffraction, optionally using a Mastersizer device from Malvern Instruments.
[0379] As used herein, “tap density” (TD) refers to the ability of a powder sample to pack together under vibration and provides a standard for measuring the cohesiveness of a powder, which may be related to its flowability and filling properties. Tap density can be determined by methods known to those skilled in the art. For example, bulk density / tap density can be determined according to European Pharmacopoeia 2.9.34. Method 1 (https: / / www.drugfuture.com / Pharmacopoeia / EP7 / DATA / 20934E.PDF; PDF downloaded November 14, 2021). Specifically, bulk density and tap density can be determined using an ERWEKA SV M 122 tap density tester equipped with a 100 mL glass cylinder. Approximately 30 g of powder is poured into a 100 mL graduated cylinder through a funnel. Bulk density is calculated by dividing the amount of powder (g) by the measured volume (mL). The tap density is then determined as follows:
[0380] Step (i): Tap the sample 10 times and read the volume V. 10 ;
[0381] Step (ii): Tap the sample 500 times (10+490) and read the volume V. 500 ;
[0382] Step (iii): Tap the sample 1250 times (500 + 750), and read the volume V. 1250 ;
[0383] Step (iv): Tap the sample 2500 times (1250+1250), and read the volume V.2500 ;
[0384] Step (v): If V 500 and V 1250 If the difference exceeds 2 mL, repeat the tapping: that is, tap the sample 1250 times and repeat until the difference is less than 2 mL.
[0385] Bulk density = weight of sample before impact / volume of sample.
[0386] Tap density = weight after tapping / volume.
[0387] calculate:
[0388] Bulk density = m(mg) / V0(mL)
[0389] Tap density = m(mg) / V 2500 (mL)

[0480] As used in this article, the term "C" 最大 "Refers to the maximum plasma concentration of olanzapine."
[0481] Unintentionally bound by theory, it is believed that after subcutaneous injection of the disclosed pharmaceutical composition, the organic solvent diffuses and the block copolymer (which is insoluble in aqueous media) precipitates, thereby forming a reservoir encapsulating olanzapine. Through drug diffusion and / or gradual reservoir degradation, olanzapine is slowly released from the reservoir, achieving and maintaining therapeutic levels of the drug over a certain period of time. In some embodiments, this period is 28 days ± 5 days, for example 25 days, 26 days, 27 days, 28 days, 29 days, 30 days, or 31 days. In some embodiments, this period is 30 days or about 30 days. In some embodiments, this period is 60 days or about 60 days.
[0482] In the method of this disclosure, the pharmaceutical composition of this disclosure is administered subcutaneously once a month. Therefore, a treatment regimen using the composition of this disclosure comprises a series of monthly subcutaneous injections.

[0513] In some aspects of the disclosed treatment methods, administration of the drug composition to a patient via subcutaneous injection results in a plasma concentration of at least 10 ng / mL of olanzapine for at least 21 days out of a 30-day period following the injection. In these aspects, the 21 days for an olanzapine plasma concentration of at least 10 ng / mL are not necessarily the first 21 days of the 30-day period following the injection, nor are they necessarily a consecutive 21-day timeframe.
[0514] In some aspects of the disclosed treatment methods, administration of the drug composition to a patient via subcutaneous injection results in a plasma concentration of at least 20 ng / mL of olanzapine for at least 21 days within a 30-day period following the injection.

[0517] In some aspects, this disclosure relates to a method of treating a patient with olanzapine, the method comprising: a) providing a kit of this disclosure; b) removing the mixture from a container in the kit containing a mixture of an organic solvent, a diblock copolymer, and a triblock copolymer; c) adding the mixture from b) to a container in the kit containing olanzapine, and then mixing to form a subcutaneous olanzapine pharmaceutical composition; and d) subcutaneously administering the subcutaneous olanzapine pharmaceutical composition to a patient requiring olanzapine treatment; wherein the treatment effectively treats the patient for approximately one month.
[0518] In some aspects of the disclosed treatment method, administration of the pharmaceutical composition to a patient via subcutaneous injection results in the patient scoring lower on the Positive and Negative Syndrome Scale (PANSS) than the patient scored before receiving the subcutaneous injection of the composition. In some aspects, the disclosed treatment method is superior to placebo in reducing the total PANSS score, for example, by 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 points relative to placebo, preferably at least 6 points, more preferably at least 8 points, and most preferably at least 10 points.
[0519] The PANSS is a 30-item scale used to assess positive and negative symptoms of schizophrenia (Kay SR, Fiszbein A, and Opler LA, The Positive and Negative Syndrome Scale (PANSS) for Schizophrenia, Schizophr Bull 1987, 13(2):261-76). The PANSS is used to identify the presence and severity of psychopathological symptoms, the relationships between these symptoms, and the overall psychopathological state. Each item is rated on a 7-point scale, from 1 (none) to 7 (extreme). The positive symptom scale includes 7 items with a maximum score of 49; the negative symptom scale includes 7 items with a maximum score of 49; and the general psychopathology scale includes 16 items with a maximum score of 112.
[0520] In some aspects of the disclosed treatment methods, administration of the drug composition to patients via subcutaneous injection resulted in patients scoring lower on the Clinical Global Impression-I (CGI-I) scale than they had before receiving the subcutaneous injection of the composition.
[0521] The CGI-I scale allows for a comprehensive assessment of the overall improvement in a patient's symptoms. The CGI-I scale uses a 7-point scale to rate the degree of improvement in patient symptoms, ranging from 1 (significant improvement) to 7 (significant deterioration). See Guy, W., ECDE U Manual of Psychopharmacology Assessment (Revised), Rockville (Maryland): U.S. Department of Health, Education and Welfare; Public Health Service; Administration of Alcohol, Substance Abuse and Mental Health; Institute of Psychopharmacology, National Institute of Mental Health, 1976b; 218-222.
[0522] In some aspects of the disclosed treatment methods, administration of the drug composition to patients via subcutaneous injection resulted in a lower Clinical Global Impression-Disease Severity Scale (CGI-S) score than the score before receiving the subcutaneous injection of the composition.
[0523] CGI-S allows raters to assess a patient's current disease severity on a scale of 1 to 7, where 1 = normal / no disease, 2 = borderline mental illness, 3 = mild illness, 4 = moderate illness, 5 = significant illness, 6 = severe illness, and 7 = very severe illness. See Guy, W., ECDE U Manual of Psychopharmacology Assessment (Revised), Rockville (Maryland): U.S. Department of Health, Education and Welfare; Public Health Service; Administration of Alcohol, Substance Abuse and Mental Health; Institute of Psychopharmacology, National Institute of Mental Health, 1976b; 218-222.
[0524] In some aspects of the disclosed treatment methods, administration of the drug composition to a patient via subcutaneous injection resulted in a lower Patient Overall Impression-I (PGI-I) score than the patient's score before receiving the subcutaneous injection of the composition.
[0525] The PGI-I scale is a single-item patient self-assessment tool used to measure improvement in a patient's condition; patients rate their perceived changes in their condition in response to treatment. Patients are asked to select a response option on a scale of 1 to 7, where 1 = significantly improved, 2 = somewhat improved, 3 = slightly improved, 4 = no change, 5 = slightly worsened, 6 = significantly worsened, and 7 = significantly worsened. See Steinert T, Eisele F. G, Albani C, Flammer E, Borbé R.[PGI-I (patient's global impression) as an outcome and quality indicator ofpsychiatric in-patient treatment:results and concordance with doctor's assessments].Psychiatr Prax 2010;37(7):343-9.
[0526] In some aspects of the disclosed treatment methods, administration of the drug composition to patients via subcutaneous injection resulted in patients scoring higher on the Personal and Social Functioning Scale (PSP) than they had before receiving the subcutaneous injection of the composition.
[0527] The PSP is a clinician assessment tool used to measure the personal and social functioning of patients with schizophrenia. See Morosini PL, Magliano L, Brambilla L, Ugolini S, and Pioli R, Development, reliability, and acceptability of a new version of the DSM-IV Social and Occupational Functioning Assessment Scale (SOFAS) to assess routine social functioning, Acta Psychiatr Scand, April 2000; 101(4):323-9. The PSP is a single-item rating scale with a maximum score of 100 points, divided into 10 equally spaced intervals. The score is based on an assessment of the patient's functioning in four categories: 1) socially beneficial activities, including work and study; 2) personal and social relationships; 3) self-care; and 4) disruptive and aggressive behaviors. Higher scores indicate better personal and social functioning, with scores of 91 to 100 indicating adequate and good functioning, while scores below 30 indicate poor functioning requiring enhanced supervision.
[0528] In some aspects of the disclosed treatment methods, administration of the drug composition to patients via subcutaneous injection resulted in patients scoring lower on the Schizophrenia Quality of Life Scale (SQLS) Revision 4 than they had before receiving the subcutaneous injection of the composition.
[0529] The Schizophrenia Quality of Life Scale Revision 4 (Martin CR and Allan R, Factorstructure of the Schizophrenia Quality of Life Scale Revision 4 (SQLS-R4), Psychol Health Med 2007; 12(2):126-34) is a 33-item scale that produces scores on three subscales: psychosocial, motivation / energy, and symptoms / side effects. See Wilkinson G, Hesdon B, Wild D, Cookson R, Farina C, Sharma V, et al., Self-report quality of life measure for people with schizophrenia: the SQLS, Br J Psychiatry 2000, 177:42-6. Higher scores on the scale indicate a lower quality of life.
[0530] In some aspects of the disclosed treatment methods, administration of the drug composition to patients via subcutaneous injection resulted in a decrease in patients' Level 3 EuroQol five-dimensional questionnaire (EQ-5D-3L) scores.
[0531] The EuroQol 5D-3L Level 3 questionnaire is a standardized questionnaire for assessing overall health status. The EQ-5D-3L consists of two parts. In Part 1, patients rate their health status in five domains (mobility, self-care, daily activities, pain / discomfort, and anxiety / depression) on a scale of 1 to 3, where 1 = no problem, 2 = some problem, and 3 = serious problem. In Part 2, patients rate their health status on a visual analog scale on a scale of 0 to 100; a score of 0 represents the worst imaginable health status, and a score of 100 represents the best imaginable health status. See EuroQol Group, EuroQol—a new facility for the measurement of health-related quality of life, Health Policy 1990, 16:199-208; Rabin R and de Charro F, EQ-5D: a measure of health status from the EuroQol Group, Ann Med 2001, 33(5):337-43.
[0532] In some aspects of the disclosed treatment methods, administration of the drug composition results in a D2 receptor occupancy rate of 60% to 80%, optionally 65% to 80%, optionally 65% to 70%, as measured by positron emission tomography (PET).
[0533] Dopamine D2 receptor occupancy (D2RO) levels are considered one of the driving factors for the clinical efficacy and safety response of antipsychotic drugs. The currently accepted hypothesis is that D2RO receptor occupancy in the striatum should be 60% to 80% to achieve optimal antipsychotic efficacy and minimal side effects; a lower threshold is clinically necessary, while exceeding a higher threshold increases the risk of side effects, particularly extrapyramidal symptoms (EPS). The relationship between olanzapine concentration and striatal D2RO receptor occupancy is described by the Emax model as follows:
[0534]
[0535] Wherein, D2RO is the dopamine D2 receptor occupancy, Cp is the olanzapine plasma concentration, and Kd is the apparent equilibrium dissociation constant, which is the plasma concentration of the active fraction when 50% D2 receptor occupancy is observed. ROmax is the maximum achievable receptor occupancy. For most antipsychotic drugs, the ROmax value in the model is fixed at 100%. The estimated value of the Kd parameter is 11 ng / mL (Mamo D et al., D2 receptor occupancy of olanzapine pamoate depot using positron emission tomography: an open-label study in patients with schizophrenia, Neuropsychopharmacology, January 2008, 33(2):298-304).

[0559] For reference, the pharmacokinetics and dosage ratios of IM olanzapine are provided:
[0560] Intramuscular Olanzapine Pharmacokinetics
[0561] The immediate-release intramuscular injection (ZYPREXAIN TRAMUSCULAR) results in rapid absorption, with peak plasma concentrations occurring within 15 to 45 minutes. Pharmacokinetic studies in healthy volunteers showed that a 5 mg dose of intramuscular olanzapine for injection produced, on average, the maximum plasma concentration was approximately five times that produced by an equivalent dose of oral olanzapine. The AUC achieved after intramuscular administration was similar to that achieved after oral administration of the same dose. The half-life observed after intramuscular administration was similar to that after oral administration. The pharmacokinetic profile was linear within the clinically applicable range. Metabolism after intramuscular administration was qualitatively similar to that after oral administration.
[0562] Sustained-release (slowly dissolving) intramuscular injection (ZYPREXA) [Olanzapine dihydroxynaphthyl] causes systemic olanzapine plasma concentrations to remain elevated for weeks to months. ZYPREXA The basic pharmacokinetic properties of olanzapine are similar to those of daily oral olanzapine. ZYPREXA The only fundamental pharmacokinetic difference between oral and intravenous olanzapine administration is the change in slow release and rate-controlled absorption. ZYPREXA is injected every 2 or 4 weeks. It can provide olanzapine plasma concentrations similar to daily oral olanzapine doses. ZYPREXA is administered in doses of 150 mg to 405 mg every 2 or 4 weeks. Steady-state plasma concentrations were within the range known to be associated with daily oral doses of 5 to 20 mg olanzapine. Compared to the oral half-life of approximately 30 hours, intramuscular Zyprexa... The effective half-life of olanzapine after administration is approximately 30 days. (ZYPREXA injection) Subsequently, exposure to olanzapine may persist for several months. The long-term persistence of systemic olanzapine concentrations may be an important consideration in the long-term clinical management of patients. Typical systemic olanzapine plasma concentrations peak within the first week after injection and trough immediately before the next injection. The fluctuations in olanzapine plasma concentrations between peaks and troughs are comparable to those of once-daily oral administration.
[0563] Dosage ratio and oral dose correspondence
[0564] ZYPREXA The following administration regimens are available: 150 mg / 2 weeks, 300 mg / 4 weeks, 210 mg / 2 weeks, 405 mg / 4 weeks, or 300 mg / 2 weeks. Higher doses will proportionally increase systemic exposure. ZYPREXA The olanzapine exposure levels correspond to the oral olanzapine dose and dosing regimen, as detailed in the table below, “Recommended doses based on oral ZYPREXA doses”.

[0567] Example 1: Materials
[0568] The copolymer was synthesized according to the method described in US 6350812 (incorporated herein by reference), with slight modifications. Typically, the desired amount of PEG (providing a triblock copolymer) or methoxy-PEG (providing a diblock polymer) was heated at 65°C and vacuum dried in a reactor vessel for 2 hours. D,L-lactide (corresponding to the target lactic acid / ethylene oxide (LA / EO) molar ratio) and zinc lactate (1 / 1000 of the amount of lactide) were added. The reaction mixture was first dehydrated by three short vacuum / N2 cycles. The reaction mixture was heated at 140°C and rapidly degassed under vacuum. The reaction was carried out at 140°C for four days at a constant nitrogen flow rate (0.2 bar). The reaction was cooled to room temperature, its contents were dissolved in acetone, and then precipitated with ethanol. The resulting product was then dried under reduced pressure. Alternatively, the copolymer can be purchased from Corbion.
[0569] pass 1 The residual lactide content and LA / EO molar ratio of the obtained product were characterized by 1H NMR. A Brucker Advance 300MHz spectrometer was used for further analysis. 1 1H NMR spectral analysis. For all 1 ¹H NMR spectra were obtained by integrating and analyzing the characteristic peaks of PLA and PEG using TopSpin software. Chemical shifts were referenced to the solvent value of CDCl₃, δ = 7.26 ppm.
[0570] The obtained products were further characterized by gel permeation chromatography (GPC) to determine their molecular weight distribution. GPC was performed using an LC system equipped with a refractive index detector. This instrument was equipped with a series of Waters styrene columns (selected from HR4, HR3, HR2, and HR1) and maintained at a constant temperature. The sample was run at a constant flow rate in BHT-stable THF. The molecular weight distribution (Mn, Mw, and polydispersity index) was determined by routine calibration using polystyrene calibration standards.
[0571] Olanzapine polymorph II was used. Characterization included X-ray diffraction (XRD), particle size distribution, and packing density / tap density.
[0572] Typical XRD patterns obtained are as follows Figure 1As shown. The main characteristic peaks of olanzapine crystal form II are defined as the peaks at approximately 8.7, 12.5, 17.4, 19.9, 21.1, 21.6, 22.4, 24.0, 25.3 and 29.8 ± 0.2 degrees 2θ.
[0573] For the purposes of this paper, the particle size distribution (PSD) was determined as volume percentages, namely D(90) and D(3,2), and was measured by laser diffraction using a Malvern Mastersizer 2000 equipped with a Hydro 2000S dispersion unit.
[0574] Measurements were performed in a saturated aqueous dispersion medium (refractive index = 1.22 (general purpose)). The sample was added as a concentrated suspension with stirring until a 10% to 20% opacity was achieved. The results were obtained over 10 measurement cycles with a recycle time (after acoustic processing) of 30 seconds. The following parameters were used:
[0575] • Distributed unit: Hydro 2000S
[0576] • Measurement range: 0.02-2000μm
[0577] • Analysis models: General purpose, ordinary, and Mie models

[0579] • Particle shape: Irregular
[0580] • Sample refractive index: 1.709
[0581] • Absorbance: 0.01
[0582] • Dispersant: Olanzapine saturated aqueous dispersion medium
[0583] • Refractive index of the dispersive medium: 1.330
[0584] • Shading rate: 10% to 20%
[0585] Pump / mixer speed: 2500 rpm
[0586] • Liquid level sensor threshold: 64%
[0587] • Sample measurement time: 10 seconds
[0588] • Background measurement time: 10 seconds
[0589] • Repeated measurements (per aliquot): 10
[0590] • Internal ultrasound: 30 seconds at 90% power
[0591] • Recirculation time (after ultrasonic treatment): 30 seconds
[0592] • Number of measurements (equal sample divisions): 1
[0593] Sample preparation: The sample was prepared as a concentrated suspension. Using a spatula, approximately 50 to 100 mg of olanzapine sample was added to a small glass beaker, along with a few drops of saturated aqueous dispersion medium. A paste was obtained by gentle mixing. An additional 1 mL of saturated aqueous dispersion medium was then added to obtain a homogeneous, concentrated suspension.
[0594] Bulk density / tap density was determined according to European Pharmacopoeia 2.9.34. Method 1 (https: / / www.drugfuture.com / Pharmacopoeia / EP7 / DATA / 20934E.PDF; PDF downloaded on November 14, 2021).
[0595] Bulk density and tapped density were determined using an ERWEKA SVM122 tapped density tester equipped with a 100 mL glass cylinder. Approximately 30 g of powder was carefully poured into a 100 mL graduated cylinder with a funnel. Bulk density was calculated by dividing the amount of powder (g) by the measured volume (mL). Tapped density was then determined as follows:
[0596] Tap 10x - Read volume (=V) 10 )
[0597] 500 taps x (10 + 490) - read volume ( = V) 500 )
[0598] 1250 taps x (500 + 750) - read volume (= V) 1250 )
[0599] 2500 taps x (1250 + 1250) - read volume (= V) 2500 )
[0600] If V 500 and V 1250 If the difference is greater than 2 mL, repeat the tapping: that is, tap 1250x again and repeat until the difference is less than 2 mL.
[0601] Bulk density = weight of sample before impact / volume of sample.
[0602] Tap density = weight after tapping / volume.
[0603] calculate:
[0604] Bulk density = m(mg) / V0(mL)
[0605] Tap density = m(mg) / V2500 (mL)
[0606] Example 2
[0607] Pharmacokinetic studies were conducted on untreated young female dogs weighing approximately 8 kg, and test items were selected. Six animals were assigned to each treatment group and were numbered and identified before the start of the study.
[0608] Animals in the control group (Group 1) received repeated intramuscular administration of ZYPADHERA (compared to ZYPREXA sold in the United States) into the femoral muscle every 2 weeks. (Same), for 2 months. Reconstitute the reference product according to the instructions described in the SPC (Product Features Overview) to achieve an olanzapine concentration of 150 mg / mL. Administer 300 mg of olanzapine (2 mL) to each animal per injection using a 19G 1″ 1 / 2 needle.
[0609] Animals in groups 2 through 5 received a single subcutaneous injection of the corresponding test item. The olanzapine dose was fixed at 405 mg, with adjustments made according to the composition of the test item. The test item was reconstituted immediately before administration and injected using a 21G1″ needle. It was reported that injection of the test item in group 3 was more difficult compared to the other groups and therefore not optimal.

[0626] Effects of heating or rubbing the injection site on the pharmacokinetic (PK) of formulation 1 in male SD-IGS rats
[0627] This study aimed to evaluate the effects of external factors such as heating and friction at the injection site on the PK curve during the first 24 hours after olanzapine administration in male SD-IGS rats under clinically similar conditions following a single subcutaneous injection of formulation 1.
[0628] Test item D represents formulation 1, which is a pharmaceutical composition disclosed herein comprising: 30% to 32% (w / w) olanzapine; 52% to 54% (w / w) dimethyl sulfoxide; 12% to 14% (w / w) a diblock copolymer comprising polylactic acid and polyethylene glycol, the diblock copolymer having a number average molecular weight of 6.5 to 12.5 kg / mol and comprising 75% to 84% (w / w) polylactic acid by weight; and 3% to 3.5% (w / w) a triblock copolymer comprising polylactic acid and polyethylene glycol, the triblock copolymer having a number average molecular weight of 6 to 13 kg / mol and comprising 83% to 88% (w / w) polylactic acid by weight; wherein the diblock copolymer and the triblock copolymer together comprise 15% to 17.5% (w / w) of the composition by weight.
[0629] The study included three groups, with six animals in each group. The study design is shown in Table 3.1.
[0630] Table 3.1: Research-Experimental Design
[0631]
[0632] SC = Subcutaneous
[0633] All groups were administered 70 μL of formulation 1 subcutaneously, with a target dose of 80 mg / kg, which is the maximum tolerated dose of formulation 1 in SD-IGS rats.
[0634] Blood samples were collected from the tail vein of all animals using a continuous collection protocol with the following time points: before administration, 10 minutes after administration (for groups 1 and 2 only), 30 minutes, 1 hour, 2 hours, 4 hours, 4.5 hours, 5.5 hours, 12 hours, 24 hours, 48 hours, and 72 hours.
[0635] In all animal samples, olanzapine was present in all plasma samples from 10 minutes to 24 hours after administration.
[0636] Low variability in exposure parameters was observed in all groups (14% to 35%). Olanzapine plasma concentrations increased immediately in all groups, reaching C60 levels within 10 minutes of administration. 最大It then dropped to a plateau concentration, which remained there for 72 hours. In most of the animals studied, C... 最大 It occurs before the intervention, therefore C 最大 Any changes were independent of the intervention. In some animals, a modest increase in olanzapine plasma concentrations was observed after the intervention, but the effect on exposure was not significant.
[0637] Small peaks in olanzapine plasma concentrations were observed in some animals, none of which were associated with the intervention, followed by elimination similar to that in other individuals within the group, indicating that no dose dumping occurred.
[0638] All groups had the same exposure, which was determined by similar AUC. 0-72h The value indicates.
[0639] In summary, extreme manipulation of the injection site of Formulation 1, whether by heating or friction, at 0.5 or 4 hours post-injection did not affect the pharmacokinetic (PK) or local tolerance at the injection site in rats. This supports the conclusion that dose dumping of Formulation 1 is unlikely to occur in humans. Dose dumping is a phenomenon of premature and excessive drug release. This significantly increases the drug concentration in plasma, leading to side effects and potential drug-induced toxicity.
[0640] Example 4
[0641] Following promising PK results obtained in the studies described in Examples 2 and 3, further studies were conducted in humans using Formulation 1.
[0642] Pharmaceuticals are used for reconstitution. Carriers containing excipients are used for reconstitution.
[0643] The Phase I clinical trial drug includes the following components:
[0644] • A single-use vial containing olanzapine powder, or an empty vial (for placebo administration).
[0645] • A single-use PFS containing a carrier (diluent)
[0646] • Two 16-gauge needles are used for reconstitution; one is used to add the carrier to the vial, and the other is used to reconstitute the drug (formulation 1) and then draw it into the administration syringe.
[0647] • A Luer-lock disposable syringe with a Luer-lock tip
[0648] • A 21-gauge, 16mm subcutaneous injection safety needle with a needle protection device, used for subcutaneous injection.
[0649] Olanzapine, used as a sustained-release injectable suspension (Formulation 1) and carrier, should be stored at 2°C to 8°C. Under the specified storage conditions, the API (olanzapine) is a yellow powder, and the carrier is a frozen, opaque solid. Both components need to be acclimated to room temperature before reconstitution, under which conditions the drug is a yellow powder and the carrier is a clear, colorless solution. Reconstitution of the drug (i.e., the active pharmaceutical ingredient powder containing the carrier) yields a yellow, opaque suspension.
[0650] Example 5
[0651] This study was an open-label, SAD and MAD study designed to evaluate the safety, tolerability, and pharmacokinetic (PK) of formulation 1 in healthy subjects and patients diagnosed with schizophrenia or schizoaffective disorder. Healthy subjects received a subtherapeutic dose of formulation 1 up to 105 mg, and patients received a therapeutic dose up to 566 mg. Patients were clinically stable and not currently receiving antipsychotic treatment other than oral olanzapine. Eligible subjects and patients were assigned to one of eight active cohorts or a loading cohort, as detailed in Table 5.1 below.
[0652] Table 5.1: Treatment Groups in the Study
[0653]
[0654] N / A = Not applicable; sc = Subcutaneous; q1m = Once a month.
[0655] All cohorts included safety, tolerability, and enhanced PK sampling assessments.
[0656] In addition to the starting dose of 70 mg, the study followed an adaptive design: the decision to use escalating doses of formulation 1 was based on the review of PK and safety data from previous lower doses of formulation 1.
[0657] Research Results
[0658] The administration methods for all subjects and patients in all cohorts are shown in Table 5.1; none of the stop rules in the protocol were met.
[0659] Population statistics
[0660] 127 healthy subjects and patients met the enrollment criteria and were deemed eligible to enter Phase 1 of the study (oral olanzapine treatment phase).
[0661] During Phase 1 of the study, a total of 36 healthy subjects and 91 patients were enrolled (54 patients were randomized to receive a single dose of formulation 1, and 37 patients were randomized to participate in multiple doses of formulation 1).
[0662] During Phase 2, a total of 30 healthy subjects and 71 patients received at least one dose of Formulation 1 and were included in each enrolled dataset used for safety and pharmacokinetic analyses. In Phase 2 of the study, an additional 6 healthy subjects were randomly assigned to the load therapy group.
[0663] Pharmacokinetics
[0664] During the study, a washout period was established between the last oral dose of olanzapine and formulation 1, reducing the administration time from 7 days to 2 days for the single-dose cohort (4 and 5) and the multi-dose cohort (8 and 9). For non-compartmental analyses, no adjustment was made for the residual effect of oral olanzapine concentrations on formulation 1. This approach was considered effective because olanzapine residues were expected to dissipate within hours of administration of formulation 1 following the last oral dose. Therefore, its effect on the PK parameters of formulation 1 was expected to be minimal.
[0665] Oral olanzapine pharmacokinetics
[0666] Healthy subjects (2.5 and 5 mg / day) and patients (10, 15 and 20 mg / day) were given subtherapeutic doses of olanzapine orally. The treatment lasted for 7 days. Following the last oral dose, a comprehensive PK collection protocol was employed to fully characterize PK at steady state.
[0667] The obtained oral pharmacokinetic (PK) parameters are shown in Figure 3. The PK parameters and inter-individual variability are related to oral olanzapine. The data is consistent with the published data.
[0668] The systemic exposure of olanzapine (i.e., C) 最大 AUC τ,ss The dosage increases proportionally with the dose in the range of 2.5 to 20 mg.
[0669] Pharmacokinetics of Formulation 1 (Single-dose subjects and patients)
[0670] The p-value curve of olanzapine after a single escalation dose of formulation 1 administered subcutaneously is shown below. Figure 4 (healthy subjects) and Figure 5 (The patient) is shown.
[0671] Overall, the pharmacokinetic (PK) characteristics of formulation 1 were qualitatively similar in healthy subjects and patients. In patients enrolled in cohorts 4–6, olanzapine plasma concentrations of formulation 1 initially increased rapidly within 1–2 days after administration to clinically relevant levels (≥10 ng / mL; Meyer and Stahl 2021). The curves showed an initial immediate release characteristic with a gradual increase in plasma concentration, and no sudden spikes or unexplained increases in olanzapine exposure, indicating no dose dumping following subcutaneous injection of formulation 1, consistent with preclinical studies.
[0672] Olanzapine plasma levels gradually increase, reaching their maximum value within 11 to 14 days (i.e., 264 to 336 hours) after administration of doses ranging from 318 mg to 531 mg (C). 最大 The slow absorption of olanzapine following subcutaneous administration of formulation 1 was reflected in a longer apparent terminal half-life (flip-flop kinetics). The arithmetic mean t1 / 2 values for single-dose cohorts of formulation 1 (cohorts 4–6) ranged from 11 to 17 days (264 to 406 hours), depending on the dose. For clinically relevant doses, therapeutic levels were maintained over a 28-day dosing interval; thereafter, concentrations decreased in a markedly multiphasic manner until the last sample collection time point of 84 days (cohorts 1–4) or 42 days (cohorts 5 and 6).
[0673] Injection site interchangeability
[0674] In this study, 105 mg of formulation 1 was subcutaneously injected into the abdomen (cohort 2) and upper arm (cohort 3) to investigate the comparability of exposures. The pharmacokinetic (PK) curves for the two injection sites were similar. The absorption rate of olanzapine in the abdomen was similar to that in the arm, with a median t0. 最大 The values were 263 and 264 hours, respectively. C after subcutaneous injection in the upper arm 最大 and AUC 0-28d The average ratios were approximately 38% and 20% higher, respectively, than the corresponding values after subcutaneous abdominal injection. Importantly, the AUC... 0-t and AUC 0-∞ Similar exposures were observed at both injection sites. Therefore, the exposure to Formulation 1 after administration through these two injection sites was considered comparable.
[0675] Pharmacokinetics of Formulation 1 at Multiple Doses (Patients)
[0676] Multiple-dose pharmacokinetic (PK) studies of olanzapine were evaluated after three consecutive q1m injections of 283 mg or 566 mg formulation 1 (cohorts 8 and 9, respectively). The mean concentration versus time following the third subcutaneous injection of olanzapine is shown in the figure. Figure 6 and Figure 7 As shown.
[0677] In the multi-dose cohort, formulation 1 was administered three times on day 1, day 29 (week 4), and day 57 (week 8), respectively.
[0678] Following subcutaneous injection of 3q1m, the median time to reach peak plasma concentrations was 11 days and 10 days (262 and 236 hours) for cohorts 8 and 9, respectively. After reaching peak concentrations, olanzapine levels declined slowly until the last sample collection. Increased olanzapine exposure appeared to be proportional to the increase in dose in the multi-dose cohorts. Data used to calculate the arithmetic mean t1 / 2 value between cohorts 8 and 9 after the last dose of formulation 1 (third dose) ranged from 22 to 25 days (539 to 589 hours). AUC 0-tau and C 最大 The cumulative ratio (3 injections / 1 injection) indicates that in cohorts 8 and 9, the AUC 0-tau C accumulated only moderately at 1.30 and 1.14 respectively. 最大 The values are 1.09 and 0.90 respectively. This can be verified by checking C. 谷值 AUC tau and C 最大 Both NCA and popPK analyses were used to estimate the attainment of steady state. Steady state was determined once the observed and simulated steady-state values were reached. As previously stated, in cohorts 8 and 9, formulation 1 showed the lowest cumulative olanzapine levels after the second or third dose. The conclusion is that steady state was rapidly reached within two injections at the end of the second administration on day 57 (week 8). Figure 6 and Figure 7 ).
[0679] β-elimination phase half-life
[0680] In multi-compartment kinetic sustained-release scenarios, using the relevant β-elimination phase half-life instead of the observed terminal elimination phase (the observed best-fit λZ) may be beneficial for estimating the time to steady state (Gidal et al., 2017; Krause et al., 2021). The relevance of using the terminal half-life may be limited if the drug concentration decreases slowly at low levels at the end of the tested pharmacokinetic curve, as this has a small impact on overall drug exposure.
[0681] Due to the multiphase distribution of formulation 1, the β-elimination phase half-life correlated better with the steady state of formulation 1 compared to the terminal elimination phase half-life (the observed best-fit λZ). For the single-dose patient cohort, the mean β-half-life of formulation 1 was 5 to 7 days, and for the multiple-dose patient cohort, the mean β-half-life of formulation 1 was 8 to 10 days (Table 5.2).
[0682] Table 5.2: Estimated terminal (λZ) elimination half-life and β half-life
[0683]
[0684] We investigated other characteristics of formulation 1 under steady-state exposure using Pop PK modeling and simulation.
[0685] Dosage ratio
[0686] According to C 最大 Based on AUC assessment, systemic exposure increased in approximately dose-proportional manner within the treatment dose range of 283 mg to 566 mg, except for cohort 6 (531 mg formulation, 1 sc dose). In cohort 6, AUC 0-28d and AUC 0-∞ Slightly lower than expected based on exposure at other dose levels; however, this change was not clinically significant and is likely related to faster olanzapine clearance in individuals after oral administration of olanzapine and formulation 1, and a smaller sample size.
[0687] Although this study lacked the ability to assess dose proportionality, and despite the high variability of PK parameters observed, a clear trend indicated dose proportionality. This finding was also supported by popPK analysis. The observed median PK curves and PK variability of oral olanzapine and formulation 1 are shown below. Figure 8 As shown. Furthermore, PK / PD simulations correlated olanzapine concentration with D2 receptor occupancy and determined the dose at which D2 receptor occupancy occurred. The simulations also confirmed that the target dose was to achieve a D2RO ranging from 60% to 80% D2 receptor occupancy, which is related to the balance between antipsychotic efficacy and minimal side effects.
[0688] Comparability of Formulation 1 with Oral Olanzapine
[0689] Following the third injection of formulation 1 (day 57), when olanzapine plasma levels were considered to be at steady state at doses of 283 and 566 mg, the range of systemic exposure over 28 days (C) was [not specified]. 最大 ,ss, the trough plasma drug concentration on day 28 [C28d / C 谷值 [,ss] and mean plasma concentration [C 平均 The steady-state systemic exposure observed after oral olanzapine in the 10 to 20 mg dose range is comparable to that observed after oral olanzapine.
[0690] Figure 8 The median concentrations of olanzapine observed after the third dose of formulation 1 (q1m; 283 mg) and the seventh dose of oral olanzapine (10 mg / day) are shown, including the 5th and 95th percentiles, both considered as steady state. Formulation 1 (q1m; 566 mg) and oral olanzapine (20 mg / day) are shown as... Figure 8 middle.
[0691] Overall, Figure 8The figures show that the pharmacokinetic variability of formulation 1 over a 28-day dosing interval is comparable to that of oral olanzapine over a 24-hour dosing interval in terms of the 5th and 95th percentiles. Similarly, the overall exposure (i.e., AUC) is comparable and exhibits similar variability.
[0692] Relative bioavailability
[0693] Table 5.3 lists the relative bioavailability of formulation 1 and oral olanzapine. The relative bioavailability at steady state is calculated using a single dose of formulation 1 (as the steady-state AUC). tau (alternatives) after AUC inf The dose-normalized ratio divided by the AUC of oral olanzapine tau The relative bioavailability of the subcutaneous olanzapine formulation was 112%, with a 90% confidence interval close to the bioequivalence acceptance criteria (0.969, 1.291) after a single dose in patient cohorts (cohorts 4 and 6). After multiple doses in patient cohorts (cohorts 8 and 9), the relative bioavailability of formulation 1 compared to oral olanzapine was 95%, with 90% CIs of 0.855 and 1.059, respectively. Although the sample size of this study was insufficient to support a bioavailability analysis, these results support the overall similarity between formulation 1 and oral olanzapine at comparable doses.

[0701] Security assessment
[0702] Safety was assessed during the study by evaluating adverse events (AEs), clinical laboratory results (serum, hematology, urinalysis, and prolactin), vital sign measurements, ECG, physical examination, injection site pain, local tolerance, and leakage assessment. In addition, psychiatric, neurological, and clinical symptom assessments included:
[0703] • Abnormal Involuntary Movement Scale (AIMS)
[0704] • Barnes' Inability to Sit Rating Scale (BARS)
[0705] • Clinical Global Impression Scale - Disease Severity (CGI-S)
[0706] • Columbia Suicide Severity Rating Scale (C-SRS)
[0707] • Extrapyramidal Symptom Rating Scale (ESRS)
[0708] • Epworth Sleepiness Scale (ESS)
[0709] • Positive and Negative Syndrome Scale (PANSS)
[0710] According to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 guidelines, the severity of adverse events (AEs) is graded, ranging from Grade 1 (mild, asymptomatic, or mildly symptomatic) to Grade 5 (AE-related death).
[0711] Formulation 1 Research Overview
[0712] The safety and risk-benefit profile of formulation 1 was assessed using clinical safety data available to date in this study. All study cohorts have been completed. Cutoff data include all safety and pharmacokinetic (PK) data from the single-dose cohorts (cohorts 1 through 6). For the multi-dose cohorts (cohorts 8 and 9), partial PK and safety data after the third dose are available, as all patients had received three consecutive q1m injections of formulation 1 and completed the treatment phase (day 85). In cohort 8, 11 patients were in the FU phase, and 1 patient completed the study. In cohort 9, 6 patients were in the FU phase, 6 patients completed the study, and 1 patient terminated the study early during the FU phase.
[0713] Results from laboratory tests, vital signs, ECG, clinical scales, and adverse events (AEs) indicated that formulation 1 did not present any new systemic safety signals and remained consistent with the safety profile of olanzapine. No PDSS events or suspected PDSS events were observed during the study.
[0714] The injection site reactions observed in the study were related to the route of administration and did not appear to significantly alter the benefit-risk profile of formulation 1.
[0715] Safety conclusions
[0716] Safety endpoints for this study included the incidence of adverse events, changes in ECG parameters compared to baseline, selected clinical laboratory values (including prolactin) and vital signs, changes in neurological and clinical symptom assessments (e.g., PANSS, ESRS, AIMS, BARS, CGI-S, C-SRS), and other safety measures assessed throughout the study.
[0717] Overall, subcutaneous administration of olanzapine extended-release injection suspension (formulation 1) in healthy subjects and patients diagnosed with schizophrenia or schizoaffective disorder was well tolerated. Its safety profile, except for ISR, was similar to that of oral olanzapine.
[0718] No deaths or treatment-related serious adverse events occurred in this study. During the washout period following oral olanzapine administration, 4 / 127 (3.1%) participants withdrew from the study due to adverse events (2 cases of elevated LDL cholesterol, 1 case of neutropenia, and 1 case of rash); all participants were healthy subjects. In Phase 2 of the study, only 1 patient receiving a clinically relevant dose of formulation 1 (cohort 4; formulation 1 425 mg) withdrew from the study due to a Grade 3 serious adverse event of psychiatric disorder, and 1 patient in cohort 9 (multiple q1m formulation 1 566 mg) experienced a Grade 2 serious adverse event of schizophrenia during the study. The investigators and sponsor considered these two serious adverse events to be unrelated to formulation 1.
[0719] In all treatment cohorts of Phase 2, at least one healthy subject or patient experienced at least one treatment-related adverse event. The incidence of treatment-related adverse events was slightly higher in the single-dose healthy subject cohort (30.0%) compared to the single-dose patient cohort (23.8%), while the incidence was highest in the multi-dose patient cohort (44.8%). The most frequently reported treatment-related adverse events (occurring in more than 4% of healthy subjects or patients) in the single-dose healthy subject cohort were injection site erythema (6.7%) and headache (6.7%); in the single-dose patient cohort, these were headache (4.8%), somnolence (4.8%), increased appetite (4.8%), or weight gain (4.8%); and in the multi-dose patient cohort, these were obesity (13.8%) and injection site pruritus (10.3%). Treatment-related adverse events were typically grade 1 or 2 in severity. Only three healthy subjects or patients experienced grade 3 treatment-related events (one healthy subject in cohort 3 [formula 1, 105 mg, upper arm] experienced elevated ALT, one patient in cohort 5 [formula 1, 318 mg] experienced injection site abscess, and one patient in cohort 9 [multiple q1m doses of formulation 1, 566 mg] experienced injection site erythema). No grade 4 or 5 adverse events were reported during the study.
[0720] Adverse events of particular concern as defined in the protocol included ISRs (only those defined as adverse events). ISRs were observed in all treatment cohorts except for Cohort 6 (Formula 1, 531 mg). Among injection site adverse events, the most frequently reported were injection site abscesses (5 patients in all cohorts), injection site erythema (4 patients in all cohorts), and injection site pruritus (3 patients in all cohorts). Most of these injection site adverse events were grade 1 or 2 in severity; except for one grade 3 injection site abscess in Cohort 5 (Formula 1, 318 mg) and one grade 3 injection site erythema in Cohort 9 (multiple q1m Formula 1, 566 mg). Seven of these events were classified as purulent lesions: one reported 5 cases of injection site abscesses with prior inflammation, and two cases of injection site infections without a clear dose response. One injection site infection (1 patient in Cohort 4) was not considered an ISR or related to Formula 1 administration because the infection was caused by patient irritation / scratching and was therefore classified as injection site irritation. None of these incidents were classified as serious, and all have recovered and been resolved after receiving systemic antibiotic treatment.
[0721] The distribution and incidence of purulent lesions varied at each injection site; specifically, 3 / 11 (27.3%) of healthy subjects received 3 injections out of 11 arm injections, and 3 / 71 (4.2%) of patients received 3 injections out of 129 abdominal injections. None of these events affected the pharmacokinetics of formulation 1.
[0722] As expected for this type of drug, an initial increase in mean prolactin levels was observed in both treatment phases (oral olanzapine and formulation 1). However, no adverse events associated with hyperprolactinemia were observed during the study.
[0723] Overall, the injections were generally well tolerated. In cohort 6 (1531 mg dosage form), one patient had an NPRS score of 10 immediately after injection pain, one patient in cohort 5 (single dose of 1318 mg dosage form) had a score of 9, one patient in cohort 4 (1425 mg dosage form) had a score of 9, two patients in cohort 6 had scores of 8, and one patient in cohort 5 had a score of 8; all other patients had NPRS scores ≤7. Minimal and sporadic injection site pain scores were recorded after day 8. Injection site reactions were generally grade 1 or 2 in severity and transient in nature.
[0724] Clinical laboratory tests (including clinical chemistry, hematology, and urinalysis), vital signs, and physical examination results showed no clinically significant trend in mean change from baseline, nor any clinically significant outcome in these assessments. However, occasional increases in creatine kinase appeared to be dose-independent in both treatment phases. 38% of patients randomized to the multi-dose cohort experienced a weight gain ≥7% from baseline. ECG results were slightly worse in all treatment cohorts, although these were generally considered clinically insignificant. Only one patient in the single-dose cohort (cohort 5; formulation 1318 mg) experienced an adverse event of tachycardia.
[0725] No clinically significant changes were observed in PANSS, ESRS, AIMS, BARS, or ESS scores during the study. Overall, patients' CGI-S and C-SRS scores remained stable throughout the study. No confirmed or suspected PDSS events (protocol-defined adverse events used for rapid reporting) occurred during the study.
[0726] Formulation 1 Safety Overview
[0727] Safety data for formulation 1 were evaluated in 71 patients and 30 healthy subjects at doses ranging from 70 to 566 mg. Six healthy subjects receiving a carrier dose of formulation 1 were also evaluated. The systemic safety profile derived from these data was consistent with other formulations of olanzapine. In this study, there were no clinically significant changes in the assessment scales of mental, neurological, and clinical symptoms compared to baseline, including in clinically stable patients who had previously received oral olanzapine. This supports the sustained release of olanzapine after injection in formulation 1, and therefore its pharmacodynamics and systemic safety profile are comparable to oral olanzapine. Most identified ISR AEs were mild to moderate in severity and not serious. These ISR AEs did not significantly alter the benefit-risk profile of formulation 1.
[0728] Example 6
[0729] A multinational, multicenter, randomized, double-blind, parallel-group, placebo-controlled study with an open-label, long-term safety profile was conducted to evaluate the efficacy, safety, and tolerability of olanzapine extended-release suspension (formulation 1) for subcutaneous injection in adult patients with schizophrenia.
[0730] Table 6.1: Goals and End Points
[0731]
[0732] Overall Design
[0733] Patients whose schizophrenia worsened ≤8 weeks prior to screening, and those requiring psychiatric hospitalization or continued hospitalization due to schizophrenia symptoms, may be included. The study consists of two phases: Phase 1 (double-blind, placebo-controlled, efficacy and safety phase) and Phase 2 (open-label safety phase). For each patient, Phase 1 lasts 8 weeks, and Phase 2 lasts up to 48 weeks. Randomization was performed up to 8 days prior to screening. In Phase 1, patients were randomly assigned to one of the three treatment groups of Formulation 1 (318 mg once monthly [q1m], 425 mg q1m, or 531 mg q1m) or a placebo group q1m in a 1:1:1:1 ratio. To maintain blinding in Phase 1, all patients were re-randomized between Phase 1 and Phase 2; patients previously assigned to the active treatment group retained their Phase 1 treatment group in Phase 2, and patients previously assigned to the placebo group were randomly assigned to one of the active treatment groups in a 1:1:1 ratio in Phase 2. Treatment ended and follow-up was conducted 4 weeks and 8 weeks after the last dose of the clinical trial drug, respectively.
[0734] Research interventions and intervention methods
[0735] This study aimed to evaluate the efficacy, safety, and tolerability of subcutaneous olanzapine extended-release injection suspension (formulation 1) in patients with schizophrenia compared to placebo. The total study duration was up to 61 weeks, with a treatment duration of up to 56 weeks.
[0736] Number of participants:
[0737] Approximately 985 patients were screened to obtain approximately 640 randomized patients.
[0738] This study enrolled patients diagnosed with schizophrenia according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). The diagnosis was confirmed using a structured assessment tool (DSM-5 Structured Clinical Interview Clinical Trial Version [SCID-5-CT]).
[0739] An acute condition is defined as a total PANSS score of 80 to 120 (inclusive) at screening and baseline (before randomization) and a score ≥4 on at least two of the following four items on the PANSS positive subscale: hallucinatory behavior, delusions, conceptual confusion or suspicion / persecution, and a CGI-S score ≥4 at screening and baseline (before randomization) (moderate disease).
[0740] Patient inclusion criteria
[0741] Only patients who meet all of the following criteria will be randomly assigned to groups in this study:
[0742] a. The patient is a male or female of any race, and is 18 to 65 years old (inclusive) at the time of screening.
[0743] b. The patient is able to provide a signed informed consent form. Unless prohibited by local regulations, patients will be asked to consent to share their information with the vendor, who will verify that they are not currently or recently involved in another clinical study. Additionally, patients will be asked to consent to have their PANSS assessments recorded (which will be reviewed if necessary to monitor the quality of the scores).
[0744] c. According to DSM-5, the patient is currently diagnosed with schizophrenia, with a duration of >1 year. The diagnosis must be confirmed by SCID-5-CT.
[0745] d. Patients with a total PANSS score of 80 to 120 (inclusive) at screening and baseline examination (before randomization) and scores ≥4 on at least two of the following four items of the PANSS positive subscale: hallucinatory behavior, delusions, conceptual confusion, or suspicion / persecution.
[0746] e. Patients who begin to experience worsening of schizophrenia ≤8 weeks prior to screening and will benefit from psychiatric hospitalization or continued hospitalization due to schizophrenic symptoms.
[0747] f. Patients with a CGI-S score ≥4 (moderate prevalence) at screening and baseline examination (before randomization).
[0748] g. Patients who have received antipsychotic medication (excluding clozapine) in the past year must be deemed to have responded to treatment based on the investigator's judgment (and discussions with family members, caregivers, or healthcare professionals, if applicable).
[0749] h. The patient has a designated responsible person (referred to as a caregiver) who agrees to provide information about the patient's location, condition, and overall status during the outpatient portion of the study in Phase 1. Field staff must identify the caregiver during the screening visit and consider them a reliable contact. The caregiver must have regular contact with the patient (defined as at least three direct contacts per week), and this frequency of contact is expected to continue in the outpatient portion of Phase 1 (and is also recommended for the remainder of the study, including Phase 2 and FU). Regular contact with the patient is not mandatory during the Phase 1 hospitalization. The patient's caregiver will be required to sign a caregiver ICF.
[0750] i. At the time of screening, the body mass index was between 18.0 and 40.0 kg / m². 2 (Including end values).
[0751] j. Only women who test negative for β-human chorionic gonadotropin (β-HCG) at screening and baseline (serum testing should be performed and negative if urine test results are borderline) or who are infertile (documented hysterectomy, bilateral oophorectomy, or bilateral salpingectomy or congenital infertility) or postmenopausal can be included.
[0752] k. Women of childbearing age must agree not to attempt pregnancy unless they have a monogamous partner, and must agree to use a highly effective method of contraception before the first dose of IMP, and to continue using this method during the study period and for 70 days after the last dose of IMP. Highly effective methods of contraception include the following:
[0753] 1. Combined hormonal contraception with estrogen and progestin (oral, vaginal, transdermal) associated with ovulation suppression; these should be initiated during the screening visit prior to the first dose of IMP.
[0754] m. Progestin-only hormonal contraceptives (oral, injectable, implantable) associated with ovulation suppression; these should be initiated during the screening visit prior to the first dose of IMP.
[0755] n. Intrauterine devices and intrauterine hormone-releasing systems; these need to be inserted at least 2 months before screening.
[0756] o. Bilateral fallopian tube obstruction.
[0757] p. Vasectomy of the partner, provided that he is the only sexual partner and undergoes a medical evaluation of the procedure.
[0758] q. Abstinence (avoiding heterosexual intercourse) for a prescribed period is also considered a very effective method. The reliability of abstinence needs to be evaluated based on the duration of clinical studies and the patient's preferred and daily lifestyle.
[0759] r. The patient (if an adult male) is surgically infertile, or if capable of fathering children, has only a same-sex partner, or is currently using an approved method of contraception and agrees to continue using this method during the study period (and for 70 days after the last dose of IMP). Male patients whose sexual partners are women of childbearing age must use condoms, even if they are sterilized. Furthermore, male patients are prohibited from donating sperm during the study period and for 70 days after the last dose of IMP.
[0760] s. The patient is able to understand the nature of the study and comply with the protocol requirements, including the prescribed dosage regimen (oral and subcutaneous), the avoidance of concomitant medications, and hospitalization at the clinical site for at least 4 weeks; be able to read and understand written text in order to complete the patient-reported outcome measurement independently; and be able to reliably score on the assessment scale.
[0761] Patients must be willing and able to comply with the study restrictions, the required time spent at the research center during the study phase (including at least 4 weeks of on-site hospitalization), and must be willing to return to the research center for further visits (if applicable), as well as the FU procedures and assessments as specified in this agreement.
[0762] u. Patients had a stable place of residence for about 3 months prior to screening and were not expected to change their place of residence during the study participation process.
[0763] v. Based on medical history and psychiatric history, physical examination, electrocardiogram (ECG), serum chemistry, hematology, coagulation urine test and serology, the patient's health condition is determined to be good.
[0764] Patient exclusion criteria
[0765] Patients meeting any of the following criteria will not be randomly assigned in this study:

[0773] g. The patient meets the criteria for moderate to severe substance use disorder (based on DSM-5 criteria) within the past 6 months, such as chronic alcohol abuse or drug abuse (excluding caffeine or nicotine-related drug abuse). A positive urine drug test result is not exclusionary if, in the investigator's judgment, the patient does not meet the criteria for substance use disorder. In the case of such a positive result without medical interpretation, the patient's eligibility will be determined by the investigator based on the patient's background, drug use history, and discussions with family, caregivers, or healthcare professionals (if applicable).
[0774] h. The patient is currently using an antipsychotic drug with a specific LAI, or is still within the coverage phase of a particular LAI at the time of screening.

[0803] ff. Patients who have donated or received any blood, plasma, or platelet transfusions within 30 days prior to the study, or who plan to donate during the study or within 6 months of the last dose of IMP.
[0804] The patient may have a pending trial that could lead to imprisonment.
[0805] Phase 2 eligibility criteria
[0806] To proceed to Phase 2, patients must meet the following eligibility criteria:
[0807] 1. The patient has completed Phase 1.
[0808] 2. Based on the researchers' judgment, the patient was considered to have sufficient clinical stability.
[0809] 3. The patient is an outpatient (i.e., meets the RDQ criteria and is discharged before Phase 2).
[0810] Patients who do not meet the RDQ criteria but whose clinical stability is deemed sufficient to transition to Phase 2 and who may benefit from continued participation in the study may continue as inpatients in Phase 2 for up to 8 weeks. For these patients, the RDQ may be assessed periodically at the investigator's discretion; if the RDQ criteria are not met by the end of the additional 8-week hospital stay (week 16), the patient will discontinue study treatment and be required to complete ET and FU visits.
[0811] Intervention group and duration
[0812] The screening phase included two consecutive days of oral olanzapine administration prior to randomization to Phase 1 to determine tolerability (for patients who had not received oral olanzapine treatment in the past year). During Phase 1 (8 weeks), patients received two monthly subcutaneous injections of formulation 1 (318 mg, 425 mg, or 531 mg) or placebo. During Phase 2 (up to 48 weeks), all patients received up to 12 monthly injections of formulation 1.
[0813] Clinical trial drugs used in the study
[0814] IMP is defined as the test IMP and the placebo IMP matched with the test IMP.
[0815] The descriptions of the IMP (formulation 1) and placebo IMP tests are shown in Table 6.3.
[0816] Testing drugs for clinical trials
[0817] Formulation 1 mentioned in the examples is a pharmaceutical composition disclosed herein, comprising: 30% to 32% (w / w) olanzapine; 52% to 54% (w / w) dimethyl sulfoxide; 12% to 14% (w / w) a diblock copolymer comprising polylactic acid and polyethylene glycol, the diblock copolymer having a number average molecular weight of 6.5 to 12.5 kg / mol and comprising 75% to 84% (w / w) polylactic acid by weight; and 3% to 3.5% (w / w) a triblock copolymer comprising polylactic acid and polyethylene glycol, the triblock copolymer having a number average molecular weight of 6 to 13 kg / mol and comprising 83% to 88% (w / w) polylactic acid by weight; wherein the diblock copolymer and the triblock copolymer together comprise 15% to 17.5% (w / w) of the composition by weight.
[0818] Pharmaceuticals are used for reconstitution. Carriers containing excipients are used for reconstitution.
[0819] Formulation 1 requires reconstitution from the following two components: one vial containing olanzapine active pharmaceutical ingredient powder and one PFS containing a carrier (two block copolymer excipients dissolved in an organic solvent containing dimethyl sulfoxide). Prior to administration, Formulation 1 is reconstituted in the vial by adding the carrier from the PFS and mixing.
[0820] Formulation 1 is administered subcutaneously to the abdomen at q1m intervals, at a dose equivalent to 10, 15, or 20 mg / day of oral olanzapine, converted according to Table 6.2. After reconstitution, each gram of total formulation 1 contains 305 mg of olanzapine. The dosage is selected by inhaling a specific prescribed volume into the injection syringe.
[0821] Inject alternately into the right and left sides of the navel. Subsequent monthly injections should be administered in a clockwise rotation between the abdominal quadrants.
[0822] Dosage group
[0823] In this study, formulation 1 was administered at three doses: low dose (318 mg q1m), medium dose (425 mg q1m), and high dose (531 mg q1m).
[0824] Table 6.2: Dosage Conversion Between Oral Olanzapine and Formulation 1
[0825] Olanzapine oral dosage Formulation 1 Olanzapine dosage Application volume of Formulation 1 10mg 318mg 0.9mL 15mg 425mg 1.2mL 20mg 531mg 1.5mL
[0826] Placebo clinical trial drugs
[0827] Formulation 1, the placebo, consists of two components: one empty vial and one PFS containing a carrier (two block copolymer excipients dissolved in DMSO). Prior to administration, the placebo product is prepared in the vial by adding the carrier from the PFS and mixing. The dosage of Formulation 1, the placebo, is 0.8 mL.
[0828] Other components
[0829] The kits for IMP and placebo IMP contain the following:
[0830] • Two 16-gauge needles: one for adding the carrier to the vial for reconstitution, and the other for drawing the drug into the administration syringe after reconstitution.
[0831] • A 3mL Luerlock disposable syringe with a Luerlock tip
[0832] • A 21-gauge, 16mm (5 / 8-inch) safety needle for subcutaneous injection, with a needle protection device.
[0833] Table 6.3: Clinical Trial Drugs Used in the Study
[0834]
[0835] IMP = Clinical Trial Drug; INN = International Nonproprietary Name; q1m = Once a Month; sc = Subcutaneous Injection.
[0836] Permitted concomitant medication
[0837] rescue drugs
[0838] Permitted rescue medications include zolpidem, zopiclone, zaleplon, or diphenhydramine for treating insomnia; benzalkonium chloride, trihexyphenidyl, or diphenhydramine for Parkinson's disease symptoms; and propranolol and benzodiazepines for akathisia.
[0839] In addition, during the screening phase and in Phase 1, lorazepam may be used as needed, except for akathisia (anxiety) (up to 6 mg / day or not exceeding the local maximum permitted daily dose [whichever is lower]). In this case, use must be limited to no more than 72 consecutive hours, and lorazepam must not be taken within 8 hours prior to the assessment of the rating scale.
[0840] In Phase 2, lorazepam (at the locally labeled approved dose) will be permitted for use as needed for indications other than akathisia (anxiety disorder). During the study, antihistamines and anticholinergics will be permitted for the treatment of agitation and insomnia.
[0841] Antidepressants and mood stabilizers
[0842] Screening phase and phase 1 Patients who have been receiving antidepressants and / or mood stabilizers for at least 3 months prior to screening and whose dosage has not changed for at least 4 weeks prior to screening (except for indications that exclude patients from the study, such as schizoaffective disorder) may continue treatment during screening phase / phase 1. Dosage changes or initiation of new treatments with these medications are not permitted during screening phase / phase 1.
[0843] Phase 2 During Phase 2, patients who received mood stabilizers and antidepressants for at least 3 months prior to screening and whose dosage remained unchanged for at least 4 weeks prior to screening, and who continued treatment during Phase 1, will be allowed to continue treatment. New mood stabilizers are not permitted; however, the dosage of mood stabilizers may be adjusted based on specific circumstances after discussion with the MM (Medical Analyst).
[0844] Phase 2 will allow for adjustments to antidepressant dosages based on the investigator's clinical judgment. Patients who have not previously received antidepressants will be permitted to begin treatment with some antidepressants (including selective serotonin reuptake inhibitors [except fluvoxamine], serotonin and norepinephrine reuptake inhibitors, and trazodone) in Phase 2, based on the investigator's clinical judgment. Investigators are encouraged to contact MM or the sponsor before initiating any new antidepressant treatment. The use of other antidepressants (such as tricyclic and tetracyclic antidepressants and bupropion) is prohibited.
[0845] Screening period (up to 8 days before randomization to enter Phase 1) :
[0846] Patients underwent screening and assessment up to 8 days prior to randomization to Phase 1. Informed consent was provided during the screening visit prior to any study-related procedures. Patients were asked to consent to share their information with the vendor, who would verify that they were not currently or recently involved in another clinical study, unless prohibited by local regulations. Furthermore, patients were asked to consent to the recording of their PANSS assessments (for review if necessary to monitor the quality of the scores). Patients willing to participate in optional pharmacogenetic and biomarker sampling, as well as optional recorded exploratory assessments, signed separate informed consent forms (ICFs) for this purpose.
[0847] Patients whose condition worsened ≤8 weeks prior to screening (investigators should confirm the worsening based on the patient's medical records and / or medical history) and patients who benefited from schizophrenia hospitalization or continued hospitalization due to schizophrenia symptoms were eligible for inclusion in this study.
[0848] During screening, patients should have a total score of 80 to 120 (inclusive) on the Positive and Negative Syndrome Scale (PANSS) and a score of ≥4 on at least two of the following four items on the PANSS positive subscale: hallucinatory behavior, delusions, conceptual confusion, or suspicion / persecution.
[0849] Patients must have a designated responsible person (referred to as a caregiver) who agrees to provide information about the patient's location, condition, and overall status during the outpatient portion of the Phase 1 study. Field staff must identify the caregiver during the screening visit and consider them a reliable contact. Caregivers must maintain regular contact with patients (defined as at least three direct contacts per week), and this frequency of contact is expected to continue during the outpatient portion of Phase 1 (and is also recommended for the remainder of the study, including Phase 2 and the FU period). The patient's caregiver is required to sign the caregiver ICF at the time of screening.
[0850] Patients who have not yet been hospitalized will be admitted during the screening phase (for details on length of stay and discharge criteria, see the description of “Phase 1” below).
[0851] Patients gradually reduced their previous oral antipsychotic medication at a rate determined by the investigator. The tapering process should be completed before randomization.
[0852] During the screening phase, patients enrolled in the study who had not previously received oral olanzapine received two doses of oral olanzapine over two consecutive days (the second dose should be taken at least 24 hours before randomization) to assess tolerability (oral olanzapine 10 mg / day or higher [but not exceeding 20 mg / day], at the investigator's discretion). PANSS and Clinical Global Impression-Severity (CGI-S) were completed before oral olanzapine administration.
[0853] Patients who have received olanzapine treatment within the past year do not need to receive two doses of oral therapy. Researchers verified prior use, tolerability, and duration of olanzapine treatment to ensure prior tolerability.
[0854] If a patient meets all study inclusion criteria and no study exclusion criteria, but the results of the blood sample collected during the 8-day screening period are not available by day 8, the screening period can be extended by 2 days (until day 10) to obtain results to confirm the patient's eligibility. If no results are available by day 10, the patient is considered to have failed the screening, and rescreening may be considered.
[0855] Phase 1 (8 weeks) :
[0856] Phase 1 is an 8-week double-blind, placebo-controlled efficacy and safety phase (acute treatment phase).
[0857] Randomized patients had a total PANSS score of 80 to 120 (inclusive) at baseline (before randomization) and a score ≥4 on at least two of the following four items on the PANSS positive subscale: hallucinatory behavior, delusions, conceptual confusion, or suspicion / persecution.
[0858] Patients whose total PANSS score decreased by ≥20% between screening and baseline (randomized) visit were not eligible for randomization to the study.
[0859] Randomized patients received either formulation 1 (low dose [318 mg q1m], medium dose [425 mg q1m], or high dose [531 mg q1m]) or placebo subcutaneously at their second visit (week 0) and seventh visit (week 4).
[0860] At the 2nd and 7th visits, prior to administration of the clinical trial drug (IMP), the PANSS, Columbia Suicide Severity Rating Scale (C-SRS), CGI-S, and Clinical Global Impression-Improvement (CGI-I; 7th visit only [week 4]) scales were completed; all other scales and questionnaires were completed before or after IMP administration. Any assessments performed after IMP administration were completed on the day of IMP administration.
[0861] Prior to screening, patients were either outpatients or inpatients. All patients were hospitalized upon entry into the study (screening period) and remained hospitalized during the screening phase and for the first 4 weeks after randomization (until the second IMP administration). After the second injection, patients were discharged if they met all discharge criteria and the investigators deemed discharge appropriate.
[0862] Throughout Phase 1 (including inpatient and outpatient care), a window of ±3 days is permitted around the planned visit date for administration of the visit; a window of ±2 days is permitted for all other visits (during inpatient care, every effort will be made to keep the assessment on the planned date). The visit date is calculated from the date of the last IMP administration. In exceptional circumstances, at the investigator's discretion and with the permission of the Medical Supervisor (MM) or the sponsor, administration of the visit should be performed (and recorded accordingly) 5 days prior to the planned visit date.
[0863] Phase 2 (up to 48 weeks) :
[0864] After completing Phase 1 (8 weeks), eligible patients proceed to Phase 2, the safety phase (long-term safety period; up to 48 weeks). During this period, patients receive monthly subcutaneous injections of Formulation 1.
[0865] The 11th visit (week 8) was the final visit for Phase 1 and the first visit for Phase 2. To maintain blinding in Phase 1, all patients were re-randomized between Phase 1 and Phase 2; patients previously assigned to the active treatment group retained their Phase 1 treatment group (the re-randomization of patients in the Formulation 1 group was solely for maintaining blinding in Phase 1 and was, in effect, a deterministic grouping, not a randomization), while patients previously assigned to the placebo group were randomly assigned to one of the active treatment groups in a 1:1:1 ratio. At this visit, the Treatment 1 group was assigned to Phase 2 and proceeded according to the re-randomized treatment grouping. Scales, questionnaires, and other assessments were completed only once. Treatment grouping in Phase 2 was revealed on a patient-by-patient basis only after the study procedures related to the assessment of the Phase 1 efficacy and safety endpoints were completed and reported. The re-disclosure of Phase 2 treatment grouping was conducted by the sponsor or representative from weeks 8 to 12 according to a predefined procedure in the relevant study plan, provided that all requirements specified in this procedure were met. Therefore, although the administration in week 8 was grouped into phase 2, all parties were treated in a blinded manner, similar to the administration in phase 1.
[0866] The study will continue on an outpatient basis (or with inpatient care for patients requiring up to 8 weeks), with weekly telephone contact (or other similar forms of remote communication) between monthly outpatient visits. If the investigator determines that a patient's condition may worsen or pose a danger to themselves or others, the patient will be invited for ad hoc appointments and / or hospitalization if necessary, and will be treated according to the investigator's judgment. If treatment with prohibited medications, including antipsychotics other than Formulation 1, is required, the patient will discontinue study treatment and be required to complete ET and FU visits.
[0867] Complete the PANSS, C-SRS, CGI-S, and CGI-I scales before IMP administration; all other scales and questionnaires may be completed before or after IMP administration (except for the 11th visit [week 8], where all assessments must be completed before IMP administration). Any assessments conducted after IMP administration should be completed on the same day as IMP administration.
[0868] Throughout Phase 2 (including any telephone visits), a window of ±3 days is permitted around the planned visit date for administration of the visit; for any patient hospitalized at the start of Phase 2, every effort shall be made to assess them on the planned date during their hospitalization. The visit date is calculated from the date of the last IMP administration. In exceptional circumstances, at the investigator's discretion and with the permission of the MM or the sponsor, administration of the visit may be performed up to 5 days before the planned visit date (and recorded accordingly).
[0869] Patients entering Phase 2 receive up to 48 weeks of treatment. The End-of-Treatment (EOT) visit is completed 4 weeks after the patient's last injection.
[0870] Dosage adjustment :
[0871] During Phase 2, researchers may, based on clinical judgment, adjust the dosage of Formulation 1 starting from the 12th visit (week 12) (to one of the dosages provided in the protocol). Dosage adjustments are recorded in the case report form.
[0872] Procedures for potential post-injection delirium / sedation syndrome
[0873] During Phase 1 and Phase 2, patients should remain in the clinic for at least 3 hours for observation following IMP administration. In the event of a potential PDSS event, vital signs and blood samples (for patients who consent to biomarker collection) should be collected immediately upon suspicion of a potential PDSS event to determine plasma drug concentrations and biomarkers. If a suspected PDSS event is reported, toxicological blood tests should be performed on the patient immediately upon suspicion of a PDSS event. Additional pharmacokinetic samples should be collected at 3, 6, 12, and 24 hours after the event and at 24 hours after resolution, or as feasible. Additional biomarker samples should be collected at 24 hours after the event and at 24 hours after resolution, or as feasible. Vital signs should be measured concurrently with the collection of additional pharmacokinetic samples.
[0874] The total duration of patient participation in this study includes screening for up to 8 days, during which time patients will take olanzapine orally for 2 consecutive days (to determine tolerability), treatment with formulation 1 or placebo for 8 weeks (Phase 1 [Acute Treatment Period]), treatment with formulation 1 for up to 48 weeks (Phase 2 [Long-Term Safety Period]), and 4 weeks of FU.
[0875] The end of the study was defined as the last visit to the last patient.

[0894] Other assessments may include the DSM-5 Structured Clinical Interview Clinical Trial Version (SCID-5-CT) or the EuroQol Level 3 five-dimensional questionnaire.
[0895] For a description of the Positive and Negative Syndrome Scale (PANSS), see paragraph
[0418] above. Audio recordings of PANSS assessments may be made (and will be reviewed as necessary to monitor the quality of the scores).
[0896] PANSS is administered by the investigator / trained rater at screening and at all time points specified in Tables 6.4 and 6.5.
[0897] Table 6.4: Phase 1
[0898]
[0899] Table 6.5: Phase 2
[0900]
[0901] For a description of the Clinical Global Impression-I (CGI-I) scale, see paragraph
[0420] above. The CGI-I is administered by the investigator / trained rater at the time points specified in Tables 6.4 and 6.5. The CGI-I during Phase 1 and Phase 2 is related to the CGI-S score at the baseline visit (Visit 2 of Phase 1).
[0902] The Clinical Global Impression-Disease Severity (CGI-S) scale is described in paragraph
[0422] above. Investigators / trained raters completed the CGI-S at the time points specified in Tables 6.4 and 6.5.
[0903] The Patient Overall Impression-Improvement (PGI-I) scale is as described in paragraph
[0424] above (see the time points specified in Tables 6.4 and 6.5).
[0904] The Personal and Social Performance (PSP) scale is used to manage patients at the time points specified in Tables 6.4 and 6.5. It is a tool for clinician assessment, as described in paragraph
[0426] .
[0905] Other assessments
[0906] DSM-5 Structured Clinical Interview Clinical Trial Version (SCID-5-CT)
[0907] SCID-5-CT is a semi-structured interview guideline for the diagnosis of DSM-5. It is administered by clinicians familiar with the DSM-5 classification and diagnostic criteria or by trained mental health professionals during screening.
[0908] SCID-5-CT can be used to ensure a systematic review of the primary diagnoses of DSM-5, ensure that all study patients meet the inclusion and exclusion criteria of DSM-5, and characterize the study population based on current and previous psychiatric diagnoses.
[0909] Quality of life scale
[0910] The quality of life scale used in this study includes the following two indicators.
[0911] The Schizophrenia Quality of Life Scale (SQLS) Revision 4 (see paragraph
[0428] ) was administered at the time points specified in Tables 6.4 and 6.5 to record quality of life.
[0912] The Level 3 EuroQol five-dimensional questionnaire (EQ-5D-3L; see paragraph
[0430] ) was administered at the time points specified in Tables 6.4 and 6.5. This is a standardized questionnaire for assessing general health status.
[0913] Security assessment
[0914] In this study, qualified investigators assessed safety by evaluating reported adverse events (including serious adverse events, extrapyramidal symptoms, injection pain and other ISRs [local tolerability]), vital signs (blood pressure, pulse and orthostatic changes and body temperature), weight, laboratory tests, ECG, concomitant medications, all-cause discontinuation time, all-cause discontinuation rate and discontinuation rate due to adverse events (tolerance), and rating scales (including AIMS, BARS, SAS, C-SRS and CDSS).
[0915] Post-injection delirium / sedation syndrome monitoring
[0916] Patients receiving formulation 1 (based on the time points in Tables 6.4 and 6.5) will be clinically observed for at least 3 hours after administration to monitor for symptoms of potential PDSS events.
[0917] If a potential PDSS event is suspected, the Medical Management Department (MM) and the sponsor should be contacted immediately. Once a potential PDSS event is suspected, vital signs and blood samples should be collected as soon as possible to determine plasma drug concentrations and biomarkers (for patients who consent to biomarker collection). If a suspected PDSS event is reported, toxicological blood tests should be performed on the patient immediately after PDSS is suspected.
[0918] Additional pharmacokinetic samples should be collected at 3, 6, 12, and 24 hours after the event and at 24 hours after its resolution, or as practicable. Additional biomarker samples should be collected at 24 hours after the event and at 24 hours after its resolution, or as practicable. Vital signs should be measured concurrently with the collection of additional pharmacokinetic samples.
[0919] Any potential PDSS event needs to be evaluated by researchers according to the following criteria.
[0920] If a potential PDSS event occurs, IDMC will review the case and determine whether it meets all five criteria of the following PDSS clinical diagnostic definition:
[0921] 1. One or both of the conditions listed in (a) and (b):
[0922] a. At least one of the following three symptom clusters is a sign or symptom consistent with olanzapine overdose, and more than one of them is at least moderately severe:
[0923] - Seizure
[0924] -Sedation / Sleepiness
[0925] - Delirium / Confusion / Disorientation / Other cognitive impairments
[0926] - Articulation disorders / other speech disorders
[0927] - Ataxia / other movement disorders
[0928] -Extrapyramidal symptoms
[0929] -Excited / Irritable / Anxious / Uneasy
[0930] - Dizziness / weakness / general malaise
[0931] b. Any of the following signs and symptoms that lead to the patient's:
[0932] - Unable to wake up, unconscious, comatose or comatose
[0933] 2. The condition appeared within 24 hours after administration of formulation 1.
[0934] 3. This situation cannot be explained by a significant increase (i.e., overdose) in the dose of formulation 1, the initiation or addition of oral olanzapine (or other forms of olanzapine) or other sedatives.
[0935] 4. Underlying medical conditions have been ruled out, including concomitant medications or drug abuse.
[0936] 5. Olanzapine plasma levels >100 ng / mL within ≤3 hours after injection.
[0937] Example 7
[0938] In vitro release from human plasma
[0939] Commercially available human plasma was placed in a well-sealed conical flask and placed on a rail-shaking water bath. Throughout the test, the temperature was maintained at 37°C and the rotation speed was set to 100 RPM. Formulation 1 and ZYPREXA Reconstitute according to the instructions and inject directly into human plasma. At designated time points during the 72-hour period, aliquot the sample solution from the conical flask and immediately filter through a 0.45 μm syringe filter. Replace the sampled plasma volume with the same volume of fresh plasma and incubate at 37°C to maintain a constant total plasma volume in the flask. Quantify olanzapine in the collected in vitro released samples using LC-MS / MS with an ESI ion source. Studies have shown that the PDSS risk is minimized using Formulation 1 technology.
