Time-matched Difference Between the OPC-61815/Moxifloxacin and Placebo Data in Change From Baseline for QTcF in 12-lead Holter Electrocardiogram (ECG)

For each OPC-61815 dose, the upper limit of the confidence interval (CI) for the time-matched difference in the least squares (LS) mean for the change in QT corrected for heart rate by Fridericia's formula (QTcF) from baseline compared to the placebo data was evaluated to determine if it was lower than 10 msec at all postdose time points. Using a linear mixed effect model with baseline QTcF in each treatment period as a covariate, treatment, sequence, treatment period, time point, and interaction between treatment and time point as fixed effects, and subject as a random effect, point estimates and CIs for the time-matched difference in the LS mean for the change in QTcF from baseline compared to the placebo data were calculated.

Time frame: Baseline, 1h, 1.5h, 2h, 3h, 4h, 6h, 12h, 24h after dosing

Population: Central tendency analysis for OPC-61815 was performed for subjects in the Pharmacodynamic Analysis Set who appropriately completed all IMP treatments and for whom predose and postdose QT data are available for all 4 treatment periods. One subject was excluded from the central tendency analysis due to lack of QT data following OPC-61815 16 mg, OPC-61815 32 mg, and placebo administration.
