Participant Flow

Participants were recruited at five community sites - four in the United States and one in Canada. All sites were Opioid Treatment Programs (OTPs). Participants were recruited through staff referrals, on-site table events manned by research staff, as well as recruitment flyers and self-referrals.

198 participants were screened and consented. 16 participants were ineligible for randomization (for 3 participants, they were unable to collect blood, 12 participants had undetectable HCV RNA, and 1 participant was excluded per investigator decision). The remaining 182 were randomized.

Measure
Test and Treat Plus Peer Mentors Intervention Arm
Participants offered 8 weeks of glecaprevir/pibrentasvir (GLE/PIB) at OTP plus peer support. Test and treat plus peer mentors: Rapid start of HCV treatment at OTP within days of HCV diagnosis. Participants will receive 8 weeks of glecaprevir/pibrentasvir and will work with a peer mentor during and after treatment.
Standard of Care Referral Arm
Participants referred to offsite (non-OTP) location for HCV treatment. Usual care: Participants are referred to another location for HCV treatment.

Analyses were conducted with a modified intention to treat of approach, which excluded randomized participants who were found on testing to have an undetectable HCV RNA, HBsAg positive or a platelet count \<150,000.

Participants who start HCV treatment in each arm.
