Brief Summary

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

The primary objectives of this study are to describe the efficacy of:

1. 8-week treatment of SOF/LED for treatment-naïve, non-cirrhotic, HCV genotype 6
2. 12-week treatment of SOF/LED for all other HCV-6 populations

Detailed Description

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

The secondary objective of this study is to describe safety, persistency, and tolerability of SOF/LED in patients with HCV-6.
