A Study of PEGASYS (Peginterferon Alfa-2a (40KD)) in Combination With Copegus (Ribavirin) in Patients...
Hepatitis CChronicThis study will evaluate the safety and tolerability of PEGASYS plus ribavirin in previous intravenous (iv) drug users who have CHC and are currently enrolled in a methadone maintenance treatment program. The anticipated time on study treatment is 1-2 years, and the target sample size is <100 individuals.

A Study to Evaluate the Combination of Pegylated Interferon Alfa Plus Valopicitabine in Patients...
Chronic Hepatitis CThis Phase II study is being conducted in treatment-naive patients (no previous antiviral therapy for Hepatitis C infection) with genotype-1 chronic hepatitis C to evaluate the safety and effectiveness of valopicitabine alone and together with Pegylated Interferon (a drug approved by the Food and Drug Administration for the treatment of Hepatitis C infection).

Efficacy of Pegylated Interferon on Liver Fibrosis in Co-infected Patient With HIV and Hepatitis...
HIV InfectionsHepatitis C1 moreThe aim of this study is to prove the efficacy of peginterferon in HIV infected patients with liver disease caused by hepatitis C virus (HCV) when the treatment to eradicate the virus failed. This scientific proof needs a comparative study to be done including two groups of patients randomly allocated: one with the treatment (peginterferon) and the other without any treatment against HCV with a duration of 2 years. To conclude, two liver biopsies are needed; one before the study and a second 2 years after.

HCV-Smoking Cessation Study
Hepatitis CSmoking CessationA 12-week study for patients who are being treated for Hepatitis C and would like to quit smoking. During the 12 weeks of Hepatitis C treatment, the research team will have counseling sessions with the participants to discuss challenges related to Hepatitis C and smoking.

Elbasvir/Grazoprevir (EBR/GZR) and Sofosbuvir (SOF) With and Without Ribavirin (RBV) in Cirrhotic...
Hepatitis CThis is a randomized, multi-site, open-label trial of the co-administration of a fixed-dose combination (FDC) of EBR 50 mg + GZR (100 mg) (EBR/GZR) and SOF 400 mg, with and without RBV, in treatment-naïve (TN) and treatment-experienced (TE) participants with chronic HCV GT3 infection with compensated cirrhosis.

A Study of the Pharmacokinetics of Uprifosbuvir (MK-3682) and Ruzasvir (MK-8408) in Participants...
Hepatitis CChronicThis is a non-randomized, open-label, single-dose study to evaluate the pharmacokinetics (PK) of uprifosbuvir (MK-3682), the M5 and M6 metabolites of uprifosbuvir, and ruzasvir (MK-8408), in participants with moderate hepatic insufficiency (HI), participants with severe HI, and age-matched healthy control participants.

Influence of Ribavirin on the Initial Virological Response in Treatment Naïve Patients With Hepatitis...
Hepatitis CChronicThis study examined the influence of ribavirin on the initial virological response in treatment-naïve participants with chronic hepatitis C, genotype 1. Participants were randomized to 1 of 3 treatment groups to receive placebo, ribavirin monotherapy 1000 milligrams (mg) to 1200 mg orally daily depending on body weight or pegylated interferon (PEG-IFN) alfa-2a (Pegasys®) 180 micrograms (mcg) subcutaneously (SC) weekly, for 6 weeks. Following the initial 6 weeks, all participants received combination therapy with PEG-IFN alfa-2a plus ribavirin (Copegus®) for 12 weeks. If there was an initial virological response after 12 weeks of combination therapy, treatment could be continued for a further 36 weeks outside of the study.

A Study to Evaluate the Efficacy and Safety of Three Experimental Drugs in Adults With Hepatitis...
Chronic Hepatitis C InfectionThe purpose of this study is to evaluate the proportion of subjects achieving sustained virologic response 12 weeks post-treatment (SVR12) in adults with genotype 1 (GT1) chronic HCV infection, who received treatment with 3 direct-acting antiviral agents (3-DAAs; ombitasvir/paritaprevir/ritonavir and dasabuvir) with or without ribavirin.

Hepatitis C Pharmacy-based Strategy for Injectors
Hepatitis CThe aim of this study is evaluate the acceptability/usage of a newly implemented model of delivery of care, namely a community-pharmacy program, to provide access to medications to treat hepatitis C (HCV), and prevent overdose and HIV, for persons who inject drugs (PWID) with HCV who are in need of treatment. Adults will be enrolled who test positive for HCV at community sites and who agree to linkage to the community-pharmacy program through the use of patient navigators. The primary outcome of the study will be the measure of the number/% of participants who are successfully linked to the community-pharmacy program and assess HCV treatment initiation, completion, and cure. In addition, other outcomes including receipt of other medications (e.g. Naloxone, pre-exposure prophylaxis (PrEP), and medications for opioid use disorders), and self-reported substance use and HIV risk behaviors will also be measured.
