Active clinical trials for "Hepatitis C"

This study will evaluate the efficacy and safety of PEGASYS plus ribavirin in male patients with hemophilia A and chronic hepatitis C. All patients will receive PEGASYS 180 micrograms s.c. weekly plus ribavirin 1000-1200mg p.o. daily (depending on body weight) for 48 weeks. Following treatment there will be a 24 week period of treatment-free follow-up. The anticipated time on study treatment is 3-12 months, and the target sample size is <100 individuals.

The purpose of this study is to determine the efficacy, safety and tolerability of different regimens of TMC435 with standard treatment compared to standard treatment alone in participants with chronic, genotype 1, hepatitis C virus (HCV) infection who has failed previous treatment with pegylated interferon (Peg-INF-alfa-2a) and ribavirin (RBV).

The substances BI 201335 and BI 207127 are being developed for the treatment of chronic hepatitis C virus infection. BI 201335 and BI 207127 work by preventing the virus from replicating. The currently available medications pegylated interferon alfa and ribavirin for hepatitis C ca have considerable adverse events in patients and in many cases are not sufficiently effective. This is particularly the case in treatment of patients infected with genotype 1 of HCV. A combination therapy of these new substances without pegylated interferon alfa may be associated with fewer adverse events that currently available (pegylated interferon-alfa-based) medication and may also provide a treatment option to the large number of patients with contraindications or intolerance to pegylated interferon alfa. This clinical trial (1241.21) currently consists of 3 distinct studies: Part 1, Part 2 and Part 3. Part 1 (SOUND-C1) is a 2 armed study as described in experimental arms 1 and 2 below (actual enrollment: 56 patients; randomized and treated: 32) Part 2 (SOUND-C2) is a 5 armed study as described in experimental arms 3 to 7 below (actual enrollment: 465; randomized and treated: 362) Part 3 (SOUND-C3) includes 3 arms as described in experimental arms 8 to 10 below (83 patients randomized and treated)

The purpose of the study is to evaluate the potential effect of TMC435 on the sensitivity of the skin towards exposure to sunlight. TMC435 is a drug that is currently under development for treatment of chronic hepatitis C virus infection. This study will be conducted in healthy volunteers. Ciprofloxacin, a commonly used antibiotic, is used as a positive control as this drug is known to mildly increase skin sensitivity to exposure to sunlight. This study also evaluates the levels of TMC435 and ciprofloxacin in the blood circulation and the safety and tolerability of TMC435.

To establish that at least 1 dose of daclatasvir combined with standard of care (pegylated interferon and ribavirin) is safe and well tolerated and demonstrates extended rapid virologic response rates at least 35% greater than those with placebo.

The purpose of this study is to determine if the combination treatment of CTS-1027, pegylated interferon and ribavirin can improve the response rates in HCV patients who did not previously respond to pegylated interferon and ribavirin therapy.

In patients with chronic hepatitis C, the ultimate treatment goal is the improvement of liver histology and inhibition of progression to liver cirrhosis and hepatocellular carcinoma (HCC). These effects are reported to be correlated with sustained ALT improvement. Therefore, the aim of this study is to determine if a low-dose (0.25, 0.5, or 1.0 mcg/kg SC QW) PegIntron monotherapy administered for 12 weeks will result in ALT normalization in Japanese patients with chronic hepatitis C.

The purpose of this study is to determine the effect of EFV (Efavirenz) and TDF (Tenofovir disoproxil fumarate) on the pharmacokinetics of TVR (Telaprevir) and to determine the effect of TVR on the pharmacokinetics of EFV and TDF. Pharmacokinetics means how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body. Furthermore, the short-term safety and tolerability of giving TVR, EFV and TDF together will be evaluated.

The pathogenesis of chronic hepatitis C (CHC) is associated to severe oxidative stress and non-selective immunological disturbance that leads to necro-inflammation and progression of fibrosis. Previous trials suggested that antioxidant and inmunostimulant therapies may have a beneficial effect. The purpose of the study is to evaluate whether Viusid, a nutritional supplement with hepatoprotective properties, could ameliorate the oxidative stress and modulate the immune response in patients with CHC and non-responders to pegylated interferon plus ribavirin, during 24 weeks of treatment.

The purpose of this study is to evaluate the efficacy of 4 different regimens of TMC435 in combination with peginterferon alfa-2a (PegIFNα-2a) and ribavirin (RBV), defined as the proportion of patients with sustained virologic response at Week 72 (patients with undetectable plasma HCV RNA [less than 25 IU per mL undetectable] at the end of treatment and at Week 72), compared to the control group receiving PegIFN and RBV in combination with TMC435-matched placebo.
