A5380: Glecaprevir/pibrentasvir Fixed-dose Combination Treatment for Acute Hepatitis C Virus Infection (PURGE-C)

This is a study to treat participants, with or without HIV, who are found to have been recently infected with the Hepatitis C virus (HCV). This known as acute HCV.

People who are recently infected with HCV are often considered to have acute HCV. People with acute HCV have a good chance of being cured of the infection when they are treated with a combination of two drugs within the first 6 months of being infected. This study is being done to see if a shorter course of treatment will be effective if started early in the infection (Step 1). In case of failure with this shorter course of treatment, a longer and different treatment for HCV will be offered (Step 2).
