简要总结
A Clinical Study that will look at an investigational medication, SEP-363856 (called "study medication") in patients with schizophrenia and assess whether it changes:
- how the body processes (uses) glucose (blood sugar)
- how much insulin the pancreas can make. Insulin is a hormone that lowers blood sugar levels in the body.
The information from this study will help to understand any effect the study medication may have on how the body uses and stores glucose.
This study is accepting both male and female subjects. It will be held in approximately 6 locations in the United States. Participation could last up to 12 weeks.
详细描述
This is an open-label, fixed sequence, multiple dose design. Following screening evaluations, subjects will check-in to the clinical research unit. After confirmation of continuation criteria, subjects will undergo an oral glucose tolerance test (oGTT), mixed meal tolerance test (MMTT) and spirulina breath test (GEBT). After these assessments are completed, subjects will have their prior antipsychotic (PA) or any other medication with psychotropic propensity washed out (dependent on their antipsychotic elimination half-life).
Subjects will undergo SEP-363856 titration schedule, followed by the oGTT, MMTT and GEBT tests during the SEP-363856 Stable Dose Period.
Subjects will be stabilized on their prior antipsychotic, discharged from the clinical research unit, and return to the unit for the follow-up visit 7 + 2 days after discharge.

- •Male or female subjects between 18 and 65 years of age, inclusive at time of consent.
- •Subject meets Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria for a primary diagnosis of schizophrenia as established by clinical interview, using the DSM-5 as a reference and confirmed using the Structured Clinical Interview for DSM-5, Clinical Trials Version [SCID-CT]).
- •Subject must have a CGI-S score ≤ 4 (normal to moderately ill) at Screening
- •Subject must have a PANSS total score ≤ 80 at Screening and a score of ≤ 4 on the following PANSS items at Screening: P7 (hostility) and G8 (uncooperativeness)
- •Subjects' antipsychotic medication at screening must have had no dose change (minor dose adjustments for tolerability purposes are permitted) for at least eight weeks prior to the Screening visit.
排除标准
- •(this list is not all inclusive)
- •- Subject has a DSM-5 diagnosis or presence of symptoms consistent with a DSM-5 diagnosis other than schizophrenia or intellectual disability (IQ < 70).
- •Subject has attempted suicide within 12 months prior to Screening.
- •Subject answers "yes" to "Suicidal Ideation" Items 4 (active suicidal ideation with some intent to act, without specific plan) or Item 5 (active suicidal ideation with specific plan and intent) on the C-SSRS at Screening (ie. in the past 1 month) or at any subsequent C-SSRS assessment prior to dosing (ie, since last visit).
- •Subject is at risk of harming him/herself or others according to the Investigator's judgment.
