SECONDARY outcome

Timeframe: Predose up to 48 hours after administration of study drug

Population: Participants who received at least one dose of LY2886721 at the 280-mg dose level and with evaluable mean QTcF data.

The mean QTcF value at Cmax for participants administered a single dose of 280 mg LY2886721 was reported. The QT interval is a measure of the time between the start of the Q wave and the end of the T wave and was calculated from electrocardiogram (ECG) data using Fridericia's formula: QTc = QT/RR\^0.33. Corrected QT (QTc) is the QT interval corrected for heart rate and RR, which is the interval between two R waves. Time matched mean change from baseline in QTcF = time matched plasma concentration + participant + random error.
