Active clinical trials for "Hepatitis C, Chronic"

The purpose of this study is to demonstrate that the proportion of treatment-naive non-cirrhotic subjects with Genotype (GT)-1b treated with Daclatasvir (DCV)/Asunaprevir (ASV)/BMS-791325 who achieve Sustained Virologic response (SVR12), defined as Hepatitis C virus (HCV) RNA < LOQ target detected or target not detected (LOQ TD/TND) at follow-up Week 12, is significantly higher than SVR12 of current Standard of Care (SOC).

The purpose of this study is to assess the efficacy and safety of grazoprevir (MK-5172) 100 mg in combination with elbasvir (MK-8742) 50 mg in the treatment of chronic hepatitis C virus (HCV) in participants who are co-infected with human immunodeficiency virus (HIV). The primary hypothesis is that the percentage of participants who receive grazoprevir + elbasvir and achieve Sustained Virologic Response after 12 weeks of therapy (SVR12) will be greater than 70%.

The purposes of this study are: To test if 36 weeks of standard dose of ribavirin with PEGASYS® is non-inferior to standard dose of 48 weeks of ribavirin with PEGASYS® in SVR for patients with RVR and HVL To test if the 72 weeks of treatment with PEGASYS® plus standard dose ribavirin is superior to 48 weeks of the same treatment for patients with HCV RNA seropositivity at week 12

The purpose of this study is to evaluate the safety and efficacy of ABT-450/ritonavir/ABT-267 (ABT-450/r/ABT-267; ABT-450 also known as paritaprevir; ABT-267 also known as ombitasvir) and ABT-333 (also known as dasabuvir) coadministered with ribavirin (RBV) in hepatitis C virus (HCV) genotype 1-infected adults taking methadone or buprenorphine ± naloxone.

This research protocol "Comparative pharmacokinetics and pharmacodynamics of peginterferon Bacterial Intravenous Protein 48 kilodaltons (BIP48) and 40 kilodaltons (40kDa) in healthy volunteers." This is a Phase I clinical trial which will compare pharmacokinetic and pharmacodynamic parameters, and safety of two products: peginterferon alfa-2a (PEGASYS ®) and BIP48. It will be a double-blind, randomized crossover with a rest period (wash-out) of 4 weeks. The study population will be 32 healthy male volunteers to whom will be administered a single dose of 180 microgram of each product, subcutaneously. The study will have a total duration of 14 days in each treatment step. The serum concentration of PEG-interferon for both products, measured by enzyme immunoassay (EIA) and by antiviral activity of PEG-interferon, is the main variable.For this purpose 15 samples of each volunteers will be needed. Clinical and laboratory variables, useful as pharmacodynamics parameters Beta-2 microglobulin (β2M) - 2'5'oligoadenylate synthetase - oligoadenylate synthetase (OAS)- and neopterin) and safety evaluation, will be measured.

This study will evaluate the safety and efficacy of combination treatment with grazoprevir (MK-5172) + elbasvir (MK-8742) for cirrhotic and non-cirrhotic participants with chronic Genotype 1 (GT1) hepatitis C virus (HCV) infection and chronic kidney disease (CKD). The primary study hypothesis is that the proportion of HCV GT1-infected CKD participants within the Immediate Treatment and Intensive Pharmacokinetics (PK) groups achieving a sustained viral response 12 weeks after the end of all study treatment (SVR12) will be >45%.

This is an open-label, multi center study of treatment-naive non-cirrhotic subjects with genotype 1 chronic Hepatitis C Virus. All subjects will receive telaprevir (TVR) in combination with sofosbuvir (SOF) for 12 weeks.

The purpose of this study to evaluate the efficacy, safety and tolerability of TMC435 in combination with Peginterferon alfa-2a (PegINF alfa-2a) and ribavirin (RBV) in both treatment-naïve and treatment experienced, chronic hepatitis C (HCV) virus, genotype-4 infected patients.

This randomized, double-blind, placebo-controlled, 3-part study will assess the safety, tolerability, and pharmacokinetics of orally administered ALS-002200 in healthy volunteers (HV) and subjects with chronic hepatitis C (CHC) genotype 1 infection. Part 1 will assess single ascending dosing pharmacokinetics and safety in HV. Part 2 will assess food effects on pharmacokinetics in HV. Part 3 will assess multiple ascending dosing pharmacokinetics and safety in subjects with CHC genotype 1 infection.

This open-label, multicenter, treatment response guided study will evaluate the sustained virological response and safety of the triple combination therapy boceprevir, Pegasys (peginterferon alfa-2a) and Copegus (Ribavirin) in previously untreated patients with genotype 1 chronic hepatitis C. In the lead-in phase, patients will receive a dual combination therapy of Pegasys and Copegus for 4 weeks. In the following triple combination therapy phase, 800 mg boceprevir, 180 mcg Pegasys and 1000-1200 mg Copegus will be administered for 24, 32 or 44 weeks; the duration depending on the patient's treatment response. The anticipated time on study treatment is up to 48 weeks.
