Trial to Evaluate the Effects of OPC-34712 on QT/QTc in Subjects With Schizophrenia or Schizoaffective Disorder
29. září 2015 aktualizováno: Otsuka Pharmaceutical Development & Commercialization, Inc.
A Parallel-arm, Double-blind, Placebo and Positive Controlled Multiple Oral Dose Administration Trial to Evaluate the Effects of OPC-34712 on QT/QTc in Subjects With Schizophrenia or Schizoaffective Disorder
The purpose of this study is to establish pharmacodynamics (PD), pharmacokinetics (PK), and adverse event (AE) profile of OPC-34712 administered to schizophrenic/schizoaffective subjects. The goals of this trial are three-fold:
- To determine the effect of OPC-34712 on the individual QT interval (QTcI) corrected for placebo
- To determine the effect of moxifloxacin on QTcI
- To examine the concentration-effect relationship of OPC-34712 and moxifloxacin on QTcI

Time-matched QTcI Change From Baseline (Day -1) Corrected for Placebo on Day 11 Following Brexpiprazole Treatment.
Časové okno: Day 11 (Hours 1, 2, 3, 4, 5, 6, 8, 12, 16, 24)
|
Pharmacodynamics endpoint is the time-matched corrected QT interval (QTcI) change from baseline (Day -1) corrected for placebo on Day 11 following brexpiprazole treatment.
The primary QT to QTc correction formula (QTcI) was determined for each participant using the participant's baseline (Day -1 placebo) ECG data.
The QT correction formula QT / (RR)k was derived using log-log-linear regression, where log (QT) = a + k × log (RR) + ε to estimate the exponent (k).
