NCT01423916

Brief Summary

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

Outcome Measures

Primary Outcomes (5)

  • Time-matched QTcI Change From Baseline (Day -1) Corrected for Placebo on Day 11 Following Brexpiprazole Treatment.

    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).

    Day 11 (Hours 1, 2, 3, 4, 5, 6, 8, 12, 16, 24)

  • Number of Participants With Adverse Events (AE) and Clinically Important Changes in Vital Signs, Physical Examinations, Laboratory Tests, and Standard ECGs (Electrocardiogram).

    Clinically important changes in vital signs, physical examinations, laboratory tests and ECGs were by and large reflected in AE/SAE (which are presented in safety section) of this report.

    AEs were recorded from Screening (informed consent was signed) during the 12-day treatment period to follow-up 30 (+ 2) days post-last dose of study medication

  • Maximum Peak Plasma Concentration (Cmax) of Brexpiprazole and Moxifloxacin.

    Pharmacokinetics endpoint is the maximum (peak) plasma concentration (Cmax) of brexpiprazole and moxifloxacin. Values for Cmax were determined directly from the observed data. Blood samples were collected on Days -1, 1, 11, and 12 at predose, and 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, and 24 hours postdose or at ET.

    Day 11

  • Time to Maximum (Peak) Plasma Concentration (Tmax) of Brexpiprazole and Moxifloxacin.

    Pharmacokinetics endpoint is the time to maximum (peak) plasma concentration (tmax) of brexpiprazole and moxifloxacin. Values for tmax were determined directly from the observed data. Blood samples were collected on Days -1, 1, 11, and 12 at predose, and 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, and 24 hours postdose or at ET.

    Day 11

  • Area Under the Plasma Concentration-time Curve During Dosing (AUCT).

    Pharmacokinetics endpoint is the area under the concentration-time curve from time zero to 24 hours (AUC0-24h) of brexpiprazole and moxifloxacin. Area under the plasma concentration-time curve during the dosing interval at steady-state (AUCT) value was estimated using the linear trapezoidal rule; the value reported represent the area under the curves to the last time point during that day. Blood samples were collected on Days -1, 1, 11, and 12 at predose, and 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, and 24 hours postdose or at ET.

    Day 11

Secondary Outcomes (8)

  • Number of Participants Noted With Time-matched Change in Mean QTcI Change From Baseline for Assay Sensitivity of Moxifloxacin Treatment Corrected for Placebo at Day 11.

    Baseline, Day 11

  • Change From Baseline in Summary of Maximum QTcI on Day 11 Minus Mean QTcI on Day -1 (Baseline).

    Baseline, Day 11

  • Change From Baseline in Summary of Maximum QTcI on Day 11 Minus Maximum QTcI on Day -1 (Baseline).

    Baseline, Day 11

  • Number of Participants With QTcI Interval Between 30 and 60 Msec on Day 11.

    Day 11

  • Number of Participants With QTcI Interval > 60 Msec on Day 11.

    Day 11
