Trial of Simplified Treatment Monitoring for 8 Weeks Glecaprevir/ Pibrentasvir (Mayret) in Chronic Hepatitis C Patients (SMART-C)
Data has shown that direct-acting antiviral (DAA) regimen of glecaprevir (300mg)/pibrentasvir (120mg), a protease inhibitor and NS5A inhibitor respectively, provides key features for HCV treatment simplification.
Eligible participants (naïve pre-cirrhosis chronic HCV patients) will be randomized (1:2) to the standard or simplified monitoring arm and will receive treatment for 8 weeks.
One post-treatment visit will be conducted 12 weeks after the final dose of study medication to evaluate the proportion of patients with undetectable HCV RNA at this time point (SVR12).
A Study to Evaluate the Pharmacokinetics, Safety, and Efficacy of Glecaprevir/Pibrentasvir in Pediatric Subjects With Genotypes 1-6 Chronic Hepatitis C Virus (HCV) Infection (DORA)
An open-label study to assess the pharmacokinetics (PK), safety, and efficacy of glecaprevir (GLE)/pibrentasvir (PIB) (Mavyret) in pediatric (children) participants divided into 4 age groups: 3 to < 6, 6 to < 9, 9 to < 12, and 12 to < 18 years of age. Within each age group, some participants will be enrolled for intensive pharmacokinetics (IPK) to characterize the PK of a particular age group and the remainder of participants will be enrolled for the evaluation of safety and efficacy of each age group. Intensive PK sampling is designed to allow for dose adjustment, based on available PK and clinical data to achieve therapeutic exposures that have been safe and efficacious in adults.

This study will enroll subjects who are at high risk for nonadherence (including active alcohol and/drug use, recent hospitalization for a psychiatric condition, previous nonadherence or missed clinic visits, or transportation issues). This study is evaluating the use of a digital medicines program to help sustain adherence and hopefully increase the chance of a cure. Study subjects will be compensated for their time in the study.

The study is both qualitative and quantitative, gathering patient’s perceptions of HCV treatment benefits before and after HCV treatment by administering surveys and conducting in-depth qualitative patient interviews. The study seeks to understand all anticipated and actual benefits patients perceive before and after viral eradication.
The study will enroll well-compensated cirrhotic as well as non-cirrhotic subjects treatment experienced with an NS5a Inhibitor + sofosbuvir and will include patients who did not complete the prescribed duration due to adverse event or any reason other than for non/poor compliance. Subjects will be randomized to 12 or 16 weeks of treatment.
Phase 1 of this study will compare the effectiveness of 3 approved HCV treatment regimens to learn whether they work equally well under real-world conditions. Phase 2 of this study will begin early 2017 and will compare the effectiveness of 2 FDA approved HCV treatments. Patients receiving HCV therapy in community and academic clinics will be offered the opportunity to consent to be randomly assigned to one of three regimens and then observed for outcomes. Once randomized, all medical care, laboratory testing, and any disease or side effect management will be assumed by usual care conditions, and patient-reported outcomes will be collected outside clinic in keeping with pragmatic design principles.
Mavyret: A Phase 3b, single arm, open-label, multicenter study to evaluate the safety and to demonstrate the non-inferiority of the sustained virologic response 12 weeks post dosing (SVR12) rates of 8 weeks of treatment with the glecaprevir (GLE)/pibrentasvir (PIB) combination regimen to the historical SVR12 rate of 12 weeks of treatment with the GLE/PIB in treatment-naïve adults with chronic HCV GT 1, 2, 4, 5, or 6 infection and compensated cirrhosis.
Subjects are being asked to take part in a research study to test two levels of alcohol services for patients with hepatitis C virus (HCV) who drink alcohol. The two levels differ in intensity of alcohol services and in whether or not they include a focus on liver health. The study will look at which level of alcohol services best decreases alcohol use among patients with HCV.
The study is evaluating the treatment of HCV genotype 1 with the Viekira regime in people coinfected with hepatitis C and HIV. Viekira regime is approved by the Food and Drug Administration (FDA) to treat people mono-infected with HCV and in people coinfected with HCV and HIV. Previous studies have achieved cure rates of 95% to 100%.

Pediatric patients infected with HCV genotypes 1, 3, 4, 5, and 6 will be treated with ledipasvir and sofosbuvir (with and without ribavirin). There will also be a placebo arm. A lead-in phase is testing the safe and effective dose. After the lead-in phase, the same patients will be treated with the combinations. There are different arms based on the ages of the children.
