Study Of The Blood Thinner, Apixaban, For Patients Who Have An Abnormal Heart Rhythm (Atrial Fibrillation) And Expected To Have Treatment To Put Them Back Into A Normal Heart Rhythm (Cardioversion) (EMANATE)

A Phase 3, Single-Blind Study to Evaluate the Effect of GS-6615 on Shortening of the QT Interval, Safety, and Tolerability in Subjects With Long QT-3 Syndrome

This study will evaluate the effect of GS-6615 on shortening of the corrected QT interval (QTc), safety, and tolerability in adults with type 3 long QT syndrome (LQT3). During the single-blind treatment period (24 weeks), participants will receive GS-6615 and/or placebo to match GS-6615. Following the single-blind treatment period, participants who have not permanently discontinued study drug will be eligible, at the discretion of the investigator, to continue receiving GS-6615 during an open-label extension phase.
