E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the efficacy (by evaluating the percentage of subjects achieving SVR12) and safety of glecaprevir/pibrentasvir (GLE/PIB) in adults with chronic hepatitis C virus (HCV) genotype (GT) 1 – 6 infection with or without compensated cirrhosis and with chronic renal impairment in both HCV treatment-naïve and treatment experienced subjects. The efficacy of GLE/PIB will be assessed based on the overall population (i.e., across treatment durations, genotypes, and cirrhosis status) and the safety of GLE/PIB will be assessed by treatment duration and cirrhosis status across genotypes |
|
E.2.2 | Secondary objectives of the trial |
To assess the percentage of subjects with HCV on-treatment virologic failure and the percentage of subjects with HCV virologic relapse across treatment durations, genotypes, and cirrhosis status. |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Optional pharmacogenetic exploratory research. Optional pharmacogenetic samples may be collected to conduct exploratory investigations into known and novel biomarkers. |
|
E.3 | Principal inclusion criteria |
1. Male or female at least 18 years of age at time of Screening.
2. Positive for anti-HCV antibody (Ab) at Screening and HCV RNA > 1,000 IU/mL at Screening.
3. Subject has an Estimated Glomerular Filtration Rate (eGFR) < 45mL/min/1.73 m2 as estimated by the MDRD method at screening according to the following formula:
eGFR (mL/min/1.73 m2) = 175 × (Serum Creatinine) – 1.154 × Age – 0.203 × (0.742 if female) × (1.212 if black), or is dialysis-dependent. Subjects requiring dialysis should have been receiving dialysis for at least 1 month prior to enrollment, and may be on hemodialysis or peritoneal dialysis.
4. Screening laboratory result indicating HCV GT1-, 2-, 3-, 4-, 5- and/or 6-infection.
5. Subject must be HCV treatment-naïve (i.e., patient has never received a single dose of any approved or investigational anti-HCV regimen) or treatment-experienced (i.e., subject has failed prior interferon [IFN] or pegylated interferon [pegIFN] with or without ribavirin [RBV], or sofosbuvir [SOF] plus RBV with or without pegIFN therapy). Prior HCV treatment with any other approved or investigational medications is not allowed. Previous HCV treatment must have been completed ≥ 2 months prior to screening. |
|
E.4 | Principal exclusion criteria |
Female who is pregnant, planning to become pregnant during the study, or breastfeeding during the study or for approximately 30 days after the last dose of study drug.
2. Positive test result at Screening for hepatitis B surface antigen (HBsAg) or anti-human immunodeficiency virus antibody (HIV Ab).
3. Clinical history of acute renal failure in the 3 months prior to screening.
4. Clinically significant abnormalities or co-morbidities, or recent (within 6 months prior to study drug administration) alcohol or drug abuse that make the subject an unsuitable candidate for this study in the opinion of the investigator.
5. Receipt of any other investigational or commercially available direct acting anti HCV agents other than sofosbuvir (e.g., telaprevir, boceprevir, simeprevir, paritaprevir, grazoprevir, daclatasvir, ledipasvir, ombitasvir, elbasvir, velpatasvir or dasabuvir). |

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
12 weeks following the last dose of study drug |
