A Phase 3b Study of Vernakalant Injection in Patients With Recent Onset Symptomatic Atrial Fibrillation (AF)(MK-6621-045) — ACT V  

Atrial Fibrillation Clinical Trial

Official title: A Phase 3b Randomized, Double-Blind, Placebo Controlled, Parallel Group Study to Evaluate the Safety and Efficacy of Vernakalant Hydrochloride Injection in Patients With Recent Onset Symptomatic Atrial Fibrillation

Status Terminated

Clinical Trial Summary

The purpose of this study is to evaluate the safety and efficacy of vernakalant injection in subjects with recent onset (AF > 3 hours to <= 7 days), symptomatic atrial fibrillation and no evidence or history of congestive heart failure.

Clinical Trial Description

Participants received a 10-minute intravenous (IV) infusion of vernakalant (3 mg/kg) or an equivalent amount of normal saline (placebo), followed by a 15-minute observation period. If the participant was still in atrial fibrillation or atrial flutter, a second 10-minute IV infusion of vernakalant (2 mg/kg) or an equivalent amount of placebo was administered unless the participant experienced any dose-stopping criteria after the start of the first infusion. If a participant converted to sinus rhythm during the first or second infusion, that infusion was completed. ;
