Exclusion Criteria:

  1. Subjects who experienced an acute exacerbation of psychosis requiring change in antipsychotic medication (with reference to drug or dose) within 90 days before screening.
  2. Subjects who become strongly affected by potent central nervous system depressants (including barbiturate) as considered by the Investigator.
  3. Subjects who have any clinically significant unstable medical condition or any clinically significant chronic disease that in the opinion of the Investigator, would limit the subject's ability to complete and/or participate in the study.
  4. Subjects with active suicidal ideation or those with a suicide attempt history.
  5. Subjects with a history or complication(s) of hypersensitivity to any medication.
  6. Subjects with a history or complication(s) of malignant tumor within 5 years before screening, except for adequately treated basal cell or squamous cell skin cancer or in situ cervical cancer. Pituitary tumors of any duration are excluded.

5. Study Description

Brief Summary
This is a multiple oral dose, randomized, double-blind, placebo-controlled study assessing the safety, tolerability and pharmacokinetics (PK) of SEP-363856 when administered qhs to Japanese subjects with schizophrenia.
Detailed Description
This multicenter study will be conducted in 2 cohorts (Cohort 1 and 2). Cohort transition will be determined by the Safety Review Team (SRT) before the start of Cohort 2. For each cohort, the target number of subjects completing the treatment period is defined as 8 for SEP-363856 group and 4 for placebo group. Subjects will be randomly assigned to either group. Dosing of the SEP-363856 group in Cohort 1 will be initiated at 50 mg SEP-363856 as an oral once daily dose for 3 consecutive days, followed by 75 mg SEP-363856 as an oral once daily dose for 4 consecutive days, and followed by 100 mg SEP-363856 as an oral once daily dose for 7 consecutive days. The SEP-363856 group in Cohort 2 will be dosed at 25 mg SEP-363856 as an oral once daily dose for 3 consecutive days, followed by 50 mg SEP-363856 as an oral once daily dose for 3 consecutive days, followed by 75 mg SEP-363856 as an oral once daily dose for 4 consecutive days, and followed by 100 mg SEP-363856 as an oral once daily dose for 7 consecutive days. In the placebo group, placebo will be orally administered according to the same administration schedule as the SEP-363856 group in each cohort.
