Active clinical trials for "Hepatitis"

Pegylation of interferon prolongs the medication half-life which has resulted in Pegylated Interferon (PEG-IFN) as the new modality for treatment of chronic hepatitis C. We current this clinical trial to assess the efficacy and safety of domestic PEG-IFN alpha-2a (Pegaferon®) in the patients with chronic hepatitis C.

The primary objective is to determine the safety of sub-cutaneous (SC) injections of TG4040 in non-cirrhotic, treatment-naïve patients chronically infected with HCV (genotype 1). Patients will be sequentially treated at an escalting dose of TG4040. All patients will be followed up to at least 6 months after his/her first injection. In addition, all patients treated at the highest dose will receive a TG4040 boost injection 6 months after the first injection, and will be followed up during an additional 6-month period.

Debio 025 (alisporivir) is an oral cyclophilin inhibitor with a new mechanism of action demonstrating potent anti-hepatitis C virus (HCV) activity in pre-clinical models and patients. The current standard of care (SOC) in HCV patients consists of a combination of peg-IFN alpha and ribavirin. Treatment duration and ribavirin dose depend on the genotype treated. Only 40-50% of patients with genotype 1 achieve a sustained viral response (SVR). This study assesses whether Debio 025 administered in combination with peg-IFN alpha 2a and ribavirin can improve the outcome of treatment in this group of patients.

This study is to evaluate the antiviral efficacy of add-on adefovir to telbivudine in non-responders to telbivudine monotherapy after 24 and 36 initial weeks. Antiviral efficacy is assessed by hepatitis B virus (HBV) DNA non-detectability (PCR <300 copies/ml) by week 104 with CHB.

The primary purpose of this study is to evaluate the safety profile and tolerability of single oral doses of BMS-650032 in subjects with chronic hepatitis C infection

The purpose of this study is to evaluate the activity and safety of telaprevir on Hepatitis C Virus (HCV) Genotype 4, alone or in combination with standard therapy, that is, pegylated-interferon-alfa-2a and ribavirin in treatment-naive (never been treated before with antiretroviral therapy) participants.

Assess the safety, tolerability and pharmacokinetics of multiple oral doses of PF-00868554 in HCV positive patient volunteers

HBe seroconversion is an important goal for anti-HBV treatment, since it is associated with a non progressive liver infection and a better clinical outcome. However, the rate of HBe seroconversion is low in HIV-HBV co-infected patients, mostly treated by tenofovir and emtricitabine. This study will evaluate the efficacy and the safety of a one-year Peg-interferon alpha 2a additional treatment in patients already treated by tenofovir and emtricitabine without reaching HBe seroconversion.

This is a phase 3, randomized, multi-center study to evaluate the efficacy and safety of albumin interferon alfa-2b (alb-IFN)in combination with ribavirin compared with peginterferon alfa-2a (PEGASYS or PEG-IFNa2a) in combination with ribavirin in subjects with chronic hepatitis C, genotype 2/3 who are IFNa treatment naive.

This study will evaluate the efficacy and safety of 4 regimens of PEGASYS plus Copegus, in patients with chronic hepatitis C (CHC) genotype 1 who have failed to respond to previous treatment with standard doses of PEGASYS plus ribavirin. Patients will be randomized to one of 4 groups, to receive a)PEGASYS 360 micrograms/week plus Copegus 1000-1200mg/day, b)PEGASYS 180 micrograms twice weekly plus Copegus 1000-1200mg/day, c)PEGASYS 360micrograms/week plus Copegus 1200-1600mg/day, or d)PEGASYS 180 micrograms twice weekly plus Copegus 1200-1600mg/day. Following 48 weeks 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 100-500 individuals.
