A Study to Evaluate the Cardiac Safety of a Single Dose of AL-335 Administered on a Background of Simeprevir and Odalasvir and of Repeated Doses of Odalasvir Administered Alone in Healthy Participants

Summary

The main purpose of this study is to assess the effect of a single supratherapeutic dose of AL-335 administered on top of multiple doses of odalasvir (ODV) and simeprevir (SMV) versus placebo on QT/QT interval corrected for heart rate (QTc) interval changes, using intersection-union test (IUT) analysis (Panel 1); to assess the effect of ODV on QT/QTc and PR interval changes after multiple supratherapeutic doses of ODV using an exposure-response (ER) approach (Panel 2); and to assess the effect of multiple supratherapeutic doses of ODV on echocardiographic left ventricular ejection fraction (LVEF) (Panel 2) in healthy participants.
