A5380: A Phase II Trial of Glecaprevir/Pibrentasvir Fixed-dose Combination Treatment for Acute Hepatitis C Virus Infection (PURGE-C)

Treatment Category


Study Description

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.

Study Purpose

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).

Target Participant

  • Age ≥18 years of age
  • With or without HIV. If living with HIV, on a stable treatment (antiretroviral regimen) or untreated due to lack of treatment per physician.
  • HIV RNA <50 and CD4 >100 cells/ mm3 (CD4 cells are a kind of white blood cell that are a measure of the immune system)
  • May not have Hepatitis B or prior Hepatitis C
  • Recently infected with HCV
  • Cannot be pregnant or breastfeeding
  • Must be willing to use birth control to prevent pregnancy
  • Must be willing to come to study visits
  • Must be able to swallow pills
  • May not have other known liver disease

Treatments Or Drugs Involved With Study

Glecaprevir/pibrentasvir (G/P) Fixed-dose Combination (FDC-single tablet) three pills by mouth once a day for 4 weeks (Step 1). If this medicine does not work for you after the 4 weeks or you become infected again while on study, you will be asked to take the G/P with or without Ribavirin for a longer time, 8-16 weeks longer.


Duration Of Study

Up to 28 weeks on Step 1 and up to an additional 40 weeks if on Step 2.
