Rapid HCV Treatment Access for Persons Who Use Drugs

This study is being done to compare two strategies to deliver HCV treatment to persons with hepatitis C virus (HCV) who also use drugs and are participating in an outpatient opioid treatment program (OTP). Participants will be randomized into one of two treatment groups: 1. Test and treat plus peer-mentors: This treatment group will be offered 8 weeks of glecaprevir/pibrentasvir (an FDA approved HCV treatment) within days of HCV diagnosis at the OTP. Participants in this group will receive treatment adherence support from a peer-mentor who is someone who has been cured of HCV infection. 2. Standard of care HCV treatment referral: This treatment group will be referred to an offsite HCV treatment location. This is the usual care for anyone who tests positive for HCV at the OTP who is not participating in this study.
