A study to determine the maximum tolerated dose of an investigational drug in subjects with schizophrenia

Study summary:

This is a single-center, randomized, double-blind, placebo-controlled, inpatient, single ascending dose (SAD) study designed to evaluate the safety, tolerability, and PK of lurasidone injectable suspension in subjects with schizophrenia. This study will determine the minimum intolerable dose (MID), the maximum tolerated dose (MTD) of lurasidone injectable suspension, and characterize the PK profiles of lurasidone and its metabolites in serum (ID-14283, ID-14326, ID-11614, ID-20219, and ID-20220) and urine (ID-14283, ID-14326, and ID-11614) in this subject population. The potential effects of gender on the PK of lurasidone injectable suspension and its metabolites will also be evaluated when applicable.


Inclusion Criteria: - 1. Subject has capacity; is willing and able to provide written consent for use and disclosure of protected health information per requirements of 45CFR164.508 (Health Insurance Portability and Accountability Act; HIPAA) prior to initiating any study procedure after being informed of the nature of the study, in the opinion of the study staff and PI. 2. Subject is male or female 18 to 65 years of age, inclusive. 3. Subject has a diagnosis of schizophrenia as per DSM-IV-TR criteria, which in the opinion of the Investigator has been clinically stable for the past 6 months. 4. Subject has a Body Mass Index (BMI) greater than or equal to 19.5 and less than or equal to 38 kg/m2. 5. Subject does not have clinically relevant abnormal laboratory values per Investigator discretion. 6. Subject does not have clinically relevant findings from vital signs measurements per Investigator discretion. 7. Female subject is eligible to enter and participate in the study if she is of: a. Non-childbearing potential (ie, physiologically incapable of becoming pregnant, including any female who is pre-menarchal or post-menopausal); - Postmenopausal females defined as being amenorrheic for greater than 2 years (or confirmed by FSH level) with an appropriate clinical profile. - Women who have not been confirmed as postmenopausal should be advised to use contraception as outlined below. - Women who have had a hysterectomy, bilateral oophorectomy or bilateral salpingectomy (as determined by subject's medical history). b. Child-bearing potential (all females ≤ 65 years of age), has a negative pregnancy test at screening and agrees to satisfy one of the following requirements: - Complete abstinence from intercourse (as part of an abstinent lifestyle) a minimum of 2 months prior to administration of the first dose of study drug, throughout the Treatment Period, and for a minimum of 3 months after completion or premature discontinuation from the study drug; or, - Established use of highly effective methods of contraception from 1 month prior to administration of the first dose of study drug, during the Treatment Period, and 60 days after completion or premature discontinuation from the study drug. - Because of the unacceptable failure rate of barrier (chemical and/or physical) methods, the barrier method of contraception must only be used in combination with a highly effective method. Post-coital methods of contraception are not permitted. 8. Male subjects with partners of child bearing potential must be practicing abstinence, part of an abstinent life style or using protocol-specified methods of birth control throughout the study and for 30 days after completion or premature discontinuation from the study drug. 9. Subject is able and willing to remain off of prior antipsychotic medication until the protocol-specified restabilization period. 10. Subject has a stable living arrangement for at least 3 months prior to Day -12 and agrees to return to a similar living arrangement after discharge. Such subjects remain eligible to participate in this protocol with approval from the PI. Chronically homeless subjects should not be enrolled. The Medical Monitor should be consulted for individual cases as Exclusion Criteria: 1. Subject had an acute exacerbation of psychiatric symptoms requiring change in antipsychotic medication (with reference to drug or dose) within 3 months (90 days) before screening. 2. Subject has known or suspected carcinoma. 3. Subject has known presence or history of renal or hepatic insufficiency. 4. Subject has significant disease(s) or clinically significant finding(s) on physical examination determined by the Investigator to pose a health concern to the subject while on study. 5. Subject has a history or presence of clinically significant abnormal ECG (based on ECG central overread report) that may jeopardize the subject's safety to participate in this study, or a screening 12-lead ECG demonstrating any one of the following: heart rate (HR) > 100 bpm, QRS > 120 msec, QTcF > 450 msec, or PR > 220 msec. 6. Subject has known history of a severe reaction to a previous antipsychotic (in the Investigator's opinion), including up to 80 mg/day of oral lurasidone. 7. Subject has a history of drug-dependence as per DSM-IV-TR criteria during the six month period immediately prior to study entry. 8. Subject has known or suspected excessive alcohol consumption, (exceeding more than 4 drinks on any single day or more than 14 drinks per week; 1 drink = 5 ounces of wine or 12 ounces of beer or 1.5 ounces of hard liquor) within 6 months of the screening visit or a positive urine alcohol test at screening. 9. Subject answers "yes" to "Suicidal Ideation" Items 4 or 5 on the C-SSRS at screening (in the past 1 month [30 days]) or at any point prior to randomization or history of suicidal behavior within the last two years. 10. Subject has significant orthostatic hypotension at screening (ie, a drop in systolic blood pressure of 30 mmHg or more and/or drop in diastolic blood pressure of 20 mmHg or more on standing). 11. Subject has presence or history (within the last year) of a medical or surgical condition that might interfere with the absorption, metabolism, or excretion of administered Lurasidone injectable suspension. 12. Subject has a history of epilepsy or risk of having seizures. 13. Subject has a positive urine alcohol at screening or on Day -12. 14. Subject has positive test results within 28 days prior to the start of the study for: 1. Human immunodeficiency virus (HIV). 2. Hepatitis B surface antigen and Hepatitis C antibody. 3. Urine drug test (marijuana, amphetamines, barbiturates, cocaine, opiates, benzodiazepines, methadone, or other drugs of abuse). However, a positive test for benzodiazepines may not result in exclusion of subjects if the Investigator determines that the use of a prescription benzodiazepine is appropriate. 4.

Subject has used of any inhibitor or inducer of CYP3A4 taken within 28 days prior to drug administration and until discharge. 16.

Subject has poor peripheral venous access or does not tolerate venipuncture that would cause difficulty for collecting blood samples. 19. Subject has experienced significant blood loss (≥ 473 mL) or donated blood within 30 days prior to screening, or intends to donate plasma or blood or undergo elective surgery during study participation or within 30 days after the last study visit. 20.
