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).
Approximately fifty HIV/HCV coinfected patients with decompensated liver disease will be enrolled in the study. Ten (up to twenty) subjects will be treated with FDC SOF/LDV (Harvoni) pre or post liver transplant and followed prospectively. Forty + subjects will be enrolled retrospectively with the intent to capture all patients who have been exposed to sofosbuvir based DAA therapies at participating sites since 1/2014, and to mirror the population being enrolled prospectively.
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.

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.
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%.

The study is evaluating the effectiveness of the hepatitis B vaccine in people infected with chronic hepatitis C. The study includes healthy volunteers (people without hepatitis C). The objective of the study is to compare the immune response of the hepatitis B vaccine people with hepatitis C vs. healthy volunteers.

Cryoglobulinemia is a disorder caused by the hepatitis C virus. The symptoms and health problems of cryoglobulinemia lead to mild to moderate to severe disease and for some people, it can be life-threatening. Treating cryoglobulinemia with direct-acting antiviral medications has been shown to reduce the symptoms of the disease and for some, it can lead to a remission and cure of cryoglobulinemia.
This objective of this clinical trial is to treat and cure hepatitis C genotype 1 and measure the effect of curing or reducing the complications of hepatitis C-related cryoglobulinemia.

The study is evaluating the safety and effectiveness of Viekira Pak to treat pediatric patients with chronic hepatitis C genotypes 1 and 4. Viekira Pak is already approved by the Food and Drug Administration to treat adults with hepatitis C. This is the first clinical trial of Viekira Pak to treat pediatric patients.
