Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this study is to evaluate the steady-state pharmacokinetics (PK) and confirm the age-appropriate dose of sofosbuvir/velpatasvir/voxilaprevir (SOF/VEL/VOX) fixed-dose combination (FDC) in pediatric participants with chronic hepatitis C virus (HCV) infection.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants will receive placebo to match SOF/VEL/VOX FDC to assess ability to swallow tablets at screening up to Day 1.
