A Clinical Study to Investigate the Effect of an Investigational Drug on Electrocardiogram Intervals in Adults With Schizophrenia.
Study Details
Study Description
Brief Summary
A clinical study to investigate the effect of an investigational drug in adults with schizophrenia by using Electrocardiogram (Picture of the electrical action of the heart). This study is accepting male and female participants between 18 years old -65 years old who have been diagnosed with schizophrenia. This study will be conducted in approximately 7 locations in the US. The study will last approximately 7 weeks.

Detailed Description
This is a Phase 1, randomized, single-dose, active and placebo controlled, 3-period crossover study of the effect of SEP-363856 150 mg on electrocardiogram (ECG) intervals in subjects with schizophrenia. SEP-363856 and matching placebo will be utilized in a double-blind fashion. Moxifloxacin will be utilized as an active control in an open-label fashion.
The primary analysis will be based on concentration-QTc modeling of the relationship between plasma concentrations of SEP-363856 or its metabolite SEP-363854 and change-from baseline QTc.

Outcome Measures
Primary Outcome Measures
- Placebo-adjusted change-from-baseline QTc interval (ΔΔQTc) [24 Hours]
Secondary Outcome Measures
- Change from baseline in heart rate, QTcF, pulse rate, and QRS intervals (∆HR, ΔQTcF, ΔPR, and ∆QRS) [24 Hours]
- If a substantial heart rate (HR) effect is observed: Change from baseline in QTcS, QTcI, and QTcP (ΔQTcS, ΔQTcI, and ΔQTcP) [24 Hours]
- Placebo-adjusted change from baseline in heart rate, pulse rate, and QRS intervals (ΔΔHR, ΔΔPR, and ΔΔQRS) [24 Hours]
- If a substantial heart rate (HR) effect is observed: Placebo-adjusted ΔQTcS, and/or ΔQTcI, and/or ΔQTcP, and/or ΔQTcF (ΔΔQTcS, ΔΔQTcI, ΔΔQTcP, ΔΔQTcF) if not selected as the primary endpoint [24 Hours]
- Categorical summary for QTcF, heart rate, pulse rate, and QRS intervals [24 Hours]
- If a substantial heart rate (HR) effect is observed: Categorical summary for QTcS, QTcI, and QTcP [24 Hours]
- Frequency of treatment-emergent changes of T-wave morphology and U-waves presence. [24 Hours]

Subject has 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
-
Female subject who is pregnant or lactating
-
Subject has any clinically significant abnormal laboratory value(s) at Screening as judged by the Investigator
-
Subject has an abnormal, clinically significant 12-lead ECG at screening

Subject has experienced significant blood loss (≥ 473 mL) or donated blood within 60 days prior to first dose of study drug; has donated plasma within 72 hours prior to the first dose of study drug or intends to donate plasma or blood or undergo elective surgery during study participation or within 60 days after the last study visit.
-
Subject has an abnormal, clinically significant 12-lead ECG at screening
-
Subject has a history of sick sinus syndrome, first, second, or third-degree AV block,myocardial infarction, NYHA Class II-IV heart failure, cardiomyopathy, pulmonary congestion, cardiac arrhythmia, prolonged QT interval, congenital long QT syndrome, family history of long QT, or moderate to severe hypokalemia
