Chronic Hepatitis CHepatitis C (HCV)1 moreA study to evaluate immune restoration following removal of viral antigen in non-cirrhotic hepatitis C virus (HCV) genotype (GT) 1a treatment-naïve and pegylated-interferon (pegIFN)/ribavirin (RBV) treatment-experienced adults receiving treatment with ombitasvir/paritaprevir/ritonavir and dasabuvir coadministered with ribavirin (RBV) for 12 weeks.

FibrosisHepatitis C ChronicThe aim of this study was to assess whether two-year treatment with Pirfenidone influence necro-inflammation, fibrosis and steatosis in patients with chronic hepatitis C.

Study to Investigate the Influence of Hepatic Insufficiency on the Pharmacokinetics of Grazoprevir...
Hepatitis CThis study will compare the pharmacokinetics (PK) of grazoprevir (MK-5172) when administered to participants with mild, moderate or severe hepatic insufficiency (assessed by the criteria of the Child-Pugh's scale) with the PK of grazoprevir when administered to healthy participants.

A Study to Evaluate the Pharmacokinetic Effect of SCH 503034 (Boceprevir) on Methadone or Buprenorphine/Naloxone...
Hepatitis C VirusIn this study, participants on methadone or buprenorphine/naloxone maintenance therapy will be given boceprevir. Blood samples will be taken at specified intervals to find out whether boceprevir affects the pharmacokinetics of methadone, buprenorphine, or naloxone.

Drug Interaction Study With BI 201335 and Methadone or Buprenorphine/Naloxone
Hepatitis COtherwise healthy subjects who are currently bein maintained on either methadone or buprenorphine/naloxone for opioid maintenance therapy who have been on a stable dose for at least 30 days will be administered BI 201335 daily to determine if a drug interaction occurs between BI 201335 and either methadone or buprenorphine/naloxone.

A Study of Different Durations of Treatment With Grazoprevir (MK-5172) in Combination With Ribavirin...
Hepatitis CThis study will compare two different durations of treatment with grazoprevir (MK-5172) in combination with ribavirin (RBV) in treatment-naïve non-cirrhotic interferon-eligible interleukin 28b CC (IL28B CC) genotype participants with genotype 1 (GT1)-positive chronic hepatitis C (CHC). Participants will be randomized to receive 12 or 24 weeks of combination therapy.

Efficacy of Sofosbuvir With Ribavirin Administered Pre-Transplant in Preventing Hepatitis C Virus...
Hepatitis CHepatocellular CarcinomaThe primary objective is to determine if the administration of a combination of sofosbuvir (SOF; GS-7977; PSI-7977) and ribavirin (RBV) to HCV-infected adults with hepatocellular carcinoma (HCC) meeting the MILAN criteria prior to undergoing liver transplantation could prevent post-transplant re-infection as determined by a sustained post-transplant virological response (HCV RNA < LLoQ) at 12 weeks post-transplant. Participants will enroll in the pretransplant treatment phase (24 or 48 weeks). Participants enrolling for 24 weeks in the pretransplant treatment phase may receive treatment for up to an additional 24 weeks in the pretransplant retreatment phase. Participants enrolling for 48 weeks in the pretransplant treatment will have a second baseline at Week 24 for combined analysis in the pretransplant retreatment phase. Participants who undergo liver transplant will stop all study drug 24 hours prior to transplant, and enter a 48-week follow-up phase to monitor for recurrent HCV infection.

Grazoprevir (MK-5172) and Elbasvir (MK-8742) Combination for Chronic Hepatitis C Virus (HCV) Genotypes...
Hepatitis CThis is a randomized, multi-site, placebo-controlled trial of a fixed dose combination (FDC) of grazoprevir (MK-5172) 100 mg + elbasvir (MK-8742) 50 mg in participants with chronic Hepatitis C Virus (HCV) genotype (GT) 1, GT4 or GT6 with inherited blood disorders. The primary hypothesis is that the proportion of participants treated with grazoprevir+elbasvir achieving Sustained Virologic Response (SVR) 12 weeks after the end of all study therapy (SVR12) will be greater than the reference rate of 40%.

Efficacy and Safety of Adding Alisporivir (DEB025) to Peginterferon (IFN) Alfa-2a (Peg-IFN Alfa-2a)...
Hepatitis CThe study is to investigate whether participants with hepatitis C virus (HCV) genotype 1 who have a history of non-response/relapse to peginterferon alfa-2a (PEG) and ribavirin (RBV) may benefit from treatment with triple therapy alisporivir (ALV; DEB025) with PEG and RBV versus placebo with PEG and RBV.

Safety and Efficacy of Daclatasvir (BMS-790052) Plus Standard of Care (Pegylated-interferon Alpha...
Hepatitis C InfectionThe purpose of this study is to identify 1 or more doses of daclatasvir, which when used in combination with pegylated interferon alpha and ribavirin, are safe and demonstrate sufficient anti-hepatitis C virus activity.
