Brief summary

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

Detailed description

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

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.
