Clinical Trial Summary

The purpose of this study is to assess the efficacy of a fixed dose combination (FDC) of glecaprevir/pibrentasvir (G/P) given for 4 weeks in acute hepatitis C (HCV)-infected participants, with or without HIV-1 coinfection.

Description:

The study will be conducted in two steps. In Step 1, participants will receive four weeks of treatment with G/P for acute HCV infection and then followed 24 weeks post treatment. Participants with HCV recurrence (reinfection, suspected relapse or undefined post-treatment viremia) or HCV virologic failure before or at the Step 1 Week 16/SVR12 (sustained virologic response 12 weeks post-treatment) visit may enter Step 2 for re-treatment. The remaining participants complete the study at Week 28 of Step 1. The study primary and secondary outcome measures pertain to Step 1.

In Step 2, participants will be re-treated with G/P with or without ribavirin (RBV) for up to 16 weeks, and followed for 24 weeks post treatment. Post-treatment follow-up for Step 2 will include visits for SVR12 determination after re-treatment.

In Step 1, study visits are scheduled at study entry, weeks 1 and 2 (on-treatment), week 4 (treatment discontinuation), and weeks 8, 12, 16 and 28 (post-treatment follow-up). In Step 2, participants will have study visits during the re-treatment period, where the number of visits depends on the re-treatment, and visits at 12 and 24 weeks post treatment. Study visits may include physical examinations, clinical assessments, blood and urine collection, questionnaires, and HCV re-infection prevention counseling.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Proportion of participants with sustained virologic response at 12 weeks post-treatment (SVR12)	SVR12 defined as achieving unquantifiable HCV RNA (less than the lower limit of quantification [LLOQ] target detected [TD] or target not detected [TND]) at study visit 12 weeks post treatment. If a participant does not have any HCV RNA measurements in this time period then the participant will be considered as SVR12 failure, unless there are preceding and subsequent HCV RNA measurements that are both LLOQ (either TD or TND).	Week 16 (12 weeks post treatment)
Primary	Proportion of participants who experienced adverse events (AEs)	Study protocol required reporting of (1) AEs Grade greater than or equal to 2, (2) AEs that led to a change in study treatment regardless of grade and (3) AEs meeting ICH definition of SAE or Expedited AE (EAE) reporting requirement. DAIDS AE Grading Table (V2.1) and DAIDS EAE Manual (V2.0) are used.	From study treatment initiation to 4 weeks after study treatment discontinuation (Week 8)
Primary	Number of participants who complete 4 weeks of treatment without discontinuation due to AEs	Number of participants who complete 4 weeks of treatment without discontinuation due to AEs	From study entry to Week 4
Secondary	Proportion of participants with HCV RNA less than LLOQ	Proportion of participants with HCV RNA less than LLOQ (TD or TND)	Weeks 1, 2, 4, 8, 12, 28
Secondary	Number of participants with HCV virologic failure	Virologic failure defined as failure to achieve unquantifiable HCV RNA and confirmed increase in HCV RNA greater than 1 log10 from on-treatment nadir	Weeks 1, 2, 4
