Daytime (AUC0-8)/8 was defined as the area under the QTc curve during the 8 hours postdose, where 0 was defined as the time of dosing (i.e., T = 0) on a given day. Daytime (AUC0-8)/8 was computed by dividing AUC0-8 by the time from dosing to the 8 hour postdose time point. QTcF is corrected QT interval using Fridericia's formula.

This endpoint will measure the plasma PK profiles of eleclazine and GS-623134. PK parameters that will be measured include AUC\_0-inf and Cmax.
AUCinf was defined as the concentration of drug extrapolated to infinite time (area under the plasma concentration versus time curve extrapolated to infinite time).
AUCinf was defined as the concentration of drug extrapolated to infinite time (area under the plasma concentration versus time curve extrapolated to infinite time).
Cmax was defined as the maximum observed concentration of drug in plasma.
Cmax was defined as the maximum observed concentration of drug in plasma.
This endpoint will measure the plasma PK profiles of GS-6615 and dofetilide. PK parameters that will be measured include Cmax, Tmax, AUC\_0-24, and AUC\_0-tlast.
The primary outcome measure is the safety and tolerability of GS-6615 including neurological findings, adverse events, clinical laboratory tests, vital signs and ECG data (PR, RR, QRS, QT, and QTc \[Fridericia\] interval).
The primary outcome measure is the PK profile of GS-6615 which will be measured with Cmax, Tmax, AUCtau, AUC0-∞, T1/2, CL/F, VSS/F, and R.
Changes in QTc intervals (Fridericia formula; QTcF) from the time-matched ECG in the primary lead V5. In case QT cannot be measured in lead V5, lead II will be designated as the primary lead * Change from the time-matched ECG on Day -1 to Day 1 for Cohorts 1-4 * Change from the time-matched ECG average of Day -1 and Day -2 to Days 1-7 for Cohort 5 and 6
