Primary outcomePrimary: HCV Treatment Completion — 22; 22 Participants
Summary
The primary objective of this pilot trial is to evaluate the feasibility of 12 weeks vs. 24 weeks of field-based directly observed therapy (DOT) for HCV therapy in a resource-limited setting. The investigators will compare treatment completion rates among 50 persons chronically infected with HCV who will be randomized to receive either 1) 12 weeks of sofosbuvir (SOF) + ribavirin (RBV) + pegylated interferon alfa-2a (PEG); or 2) 24 weeks of SOF + RBV. Treatment will be delivered daily by field workers at a location of a participants choosing. Secondary objectives are 1) To compare the efficacy of SOF+RBV with or without PEG as measured by the proportion of subjects with sustained viral response at 12 weeks after discontinuation of therapy (SVR12); 2) To evaluate the safety and tolerability of SOF+RBV with or without PEG; 3) To assess the impact of SVR12 on insulin resistance.

Eligibility Criteria
Inclusion Criteria
- Willing/able to provide consent
- Age ≥ 18
- Chronic HCV (HCV RNA positive)
- Resident of Chennai and can provide locator information
- If co-infected with HIV, must have CD4 (Cluster of Differentation 4) > 350 cells/mm3 and either: 1) ART naïve or 2) if on ART be on a tenofovir-containing regimen. If a participant's CD4 drops below 350 cells/μl (threshold for treatment in India), will have to initiate a tenofovir-containing regimen (current standard of care).
- Participants must have the following at screening:
- Alanine Aminotransferase (ALT) ≤ 10 x the upper limit of normal (ULN)
- Aspartate Aminotransferase (AST) ≤ 10 x ULN
- Hemoglobin ≥ 12 g/dl for males and 11 g/dl for females
- International normalized ratio (INR) ≤ 1.5 x ULN unless subject has known hemophilia or is stable on an anticoagulant regimen affecting INR
- Albumin ≥ 3 g/dl
- Direct bilirubin ≤ 1.5 x ULN
- Creatinine clearance ≥ 60 ml/min (Cockgroft-Gault Equation)
- Alpha fetoprotein 50 years of age with cessation (for ≥12 months) of previously occurring menses
- Of childbearing potential and negative urine pregnancy test prior to randomization and agree to one of the following from 3 weeks prior to Baseline/Day 1 until 6 months after the last dose of RBV.
- Complete abstinence from intercourse.
Or
- Consistent use of approved methods of birth control in addition to a male partner who correctly uses a condom from 3 weeks prior to Baseline/Day 1 until 6 months after the last dose of RBV.
- Male participants must agree to consistently and correctly use a condom. If their female partner is of childbearing potential, their partner must agree to use one of the study approved non-hormonal methods of birth control or a hormone-containing contraceptive, from the date of screening until 7 months after their last dose of RBV
- Male participants must agree to refrain from sperm donation for at least 7 months after the last dose of RBV.
- Of generally good health as determined by the investigator.
- Able to comply with the dosing instructions for study drug administration and willing to complete the study schedule of assessments.
Exclusion Criteria
- Pregnant/nursing female or male with pregnant/nursing female partner.
- Current or prior history of clinical hepatic decompensation (e.g., ascites, encephalopathy or variceal hemorrhage, MELD 10 mg/day)
- Use of any prohibited concomitant medications within 28 days of the Baseline/Day 1 visit.
- Contraindications to RBV therapy or PEG/RBV
- Known hypersensitivity to RBV or PEG, the metabolites or formulation excipients
- Additional exclusion criteria related to Aim 1 regimen
- Pre-existing significant psychiatric condition(s) including severe depression, severe bipolar disorder and schizophrenia. Other psychiatric disorders are permitted if the condition is well controlled with a stable treatment regimen for ≥ 1 year from screening.
- Presence of autoimmune disorders (e.g., systemic lupus erythematosus, rheumatoid arthritis, sarcoidosis).
- History of clinical significant retinal disease.
