Brief Summary: This study will evaluate the effect of oral GS-6615 on QTc interval in healthy adults with dofetilide-induced QTc prolongation.
Detailed Summary:
Sponsor: Gilead Sciences
Current Primary Outcome:
- Change in daytime QT interval corrected for heart rate using the Fridericia formula (QTcF) [ Time Frame: Up to 6 days ]
- Pharmacokinetic (PK) profiles of GS-6615 and dofetilide [ Time Frame: Predose and postdose on Days -2 through Day 4 ]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.
Original Primary Outcome: Same as current
Current Secondary Outcome: Incidence of adverse events, clinical laboratory test results, vital sign measurements, and electrocardiogram (ECG) data [ Time Frame: Up to 6 days ]
