Filter by:To identify a shorter duration of antiviral therapy (12 or 16 weeks) for the combination of daclatasvir with pegylated interferon alfa-2a and ribavirin.
To evaluate therapeutic efficacy and predicting factors of entecavir for treating patients with acute on chronic hepatitis B liver failure (ACHBLF). A total of 108 patients with ACHBLF were allocated into either a treatment group (ETV group, n=53) or a control group (n=55). The HBV DNA level, liver function and survival condition of the patients were observed for 48 weeks after enrollment. The factors possibly related to entecavir treatment efficacy were also identified.
The purpose of this study is to evaluate the effectiveness of telaprevir administered twice daily versus every 8 hours in combination with Peg-IFN-alfa-2a and ribavirin in treatment-naïve participants with chronic HCV genotype 1 infection.
This study will evaluate immune responses in patients with HBeAg-negative chronic Hepatitis B treated with Pegasys (peginterferon alfa-2a). Eligible patients will have been randomized in study ML18253 to receive Pegasys 180 mcg subcutaneously for 48 or 96 weeks. Sample collection period for each patients will occur in the first 24 weeks.
Vitamin D deficiency is commonly found in patients with chronic hepatitis C. The investigators hypothesize that the correction of hypovitaminosis D before the initiation of anti-HCV combination therapy and the maintenance of an optimal vitamin D status during antiviral therapy could improve the antiviral efficacy
This phase 2b study will evaluate the efficacy and safety of 16 and 24 weeks of response-guided duration of therapy with GS-9190 and GS-9256 in combination with Peginterferon Alfa-2a (Pegasys®) and Ribavirin (Copegus®). Additionally, the efficacy and safety of 24 weeks of GS-9256 in combination with Peginterferon Alfa-2a (Pegasys®) and Ribavirin (Copegus®) will be evaluated.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and antiviral activity of ABT-450 with ritonavir (ABT-450/r) dosed in combination with ABT-072 and ribavirin (RBV) in treatment-naïve participants with genotype 1 chronic hepatitis C virus (HCV) infection.
Filibuvir, a CYP3A4 inhibitor is being developed for the treatment of chronic Hepatitis C infection. Given the likelihood of co administration of filibuvir and methadone, this study will evaluate the effect of filibuvir on the pharmacokinetics of R/S Methadone.
Objective(s) The primary study objective is to assess the antiviral effect of 12 weeks of adefovir dipivoxil treatment in Korean patients with chronic hepatitis B and compensated liver disease. The secondary study objectives are to assess the antiviral effect, clinical benefit and safety of 52 weeks of adefovir dipivoxil treatment. Endpoint(s) The primary efficacy endpoint is "Mean log10 reduction in serum HBV DNA level from baseline to Week 12". The secondary efficacy endpoints include (a) the proportion of patients achieving serum ALT normalization at Week 52, (b) other assessments of antiviral effects (the proportion of patients achieving HBV DNA no less than 300 copies per mL at Week 52), (c)HBeAg loss, HBeAg seroconversion, HBsAg loss and HBsAg seroconversion, (d)the proportion of patients achieving serum ALT normalization at Week 12. Study Design This is an open label, multi centre phase IV study for Korean patients with chronic hepatitis B and compensated liver disease, assessing the antiviral effect of 12 weeks treatment of Adefovir dipivoxil as a primary objective and antiviral effect, clinical benefit and safety of 52 weeks treatment as secondary objectives. Patients will be screened for eligibility criteria and the baseline visit for the treatment initiation should occur no more than 4 weeks after screening. Total treatment period will be 52 weeks and patients will return to the clinic for assessments as scheduled during treatment period. After the 52 week study period, it is likely that the patient will benefit from continued treatment with commercial adefovir. If in the investigator's clinical judgement this is the case, the investigator should ensure that a routine prescription is available in a timely manner, and that no unnecessary interruption in treatment occurs. Study Population A minimum of 100 male or female Korean patients more than 18 years of age with HBeAg positive chronic hepatitis B and compensated liver disease who meet the eligibility criteria will be enrolled. Study Assessments and Procedures Potential patients will be screened prior to study entry and eligible patients who have given their consent will have further baseline assessments. Following the screening, the first doses of study medications will be given at baseline and patients will return to the clinic for assessment as scheduled during treatment period. Patients who discontinue treatment prematurely will be followed up every 4 weeks for 12 weeks following the withdrawal visit. The following key assessment and or measurement will be made at one or more visits during the study. (See section 14.1 Appendix 1. Time and event schedule): - Pregnancy test (females of child-bearing potential only) - Haematology and serum chemistry profile including prothrombin time(PT) and AFP - HBV DNA (Roche COBAS AMPLICOR HBV MONITOR Test, LLOD 300 copies per ml) - Hepatitis B markers: HBeAg(Anti HBe will be tested if HBeAg is negative), HBsAg(Anti HBs will be tested if HBsAg is negative) Investigational Product(s) Adefovir dipivoxil 10mg tablets will be supplied by GlaxoSmithKline and presented as a white to off white, round tablets, packaged in the bottle containing 30 tablets
The main purpose of this study is to determine the safety and tolerability of multiple dosing of miravirsen in subjects infected with chronic hepatitis C. Secondary purpose includes assessment of pharmacokinetics of miravirsen and assessment of miravirsen's effect on HCV viral titer.
