Filter by:This is an open label, randomized, comparative, multi-center study. Subjects will be screened within 2 weeks prior to study entry to establish eligibility. Subjects who meet all the selection criteria will be randomly assigned 1:1 to (1) once-a-week, subcutaneous Pegylated interferon alfa-2b (PegIntron) (1.5 mcg/kg body weight) or (2) oral adefovir 10 mg daily. The treatment phase will be 24 weeks for PegIntron and 48 weeks for adefovir. All subjects completing the assigned treatment phase will be followed up for an additional 48 weeks for PegIntron and 24 weeks for adefovir as observation phase. The primary objective is to establish the efficacy profile of PegIntron. Secondary objectives are to compare the efficacy profile of PegIntron with that of adefovir, compare efficacy of PegIntron in lamivudine-naïve and lamivudine-experienced subjects, and to establish the safety profile of PegIntron in treating patients with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B.
The purpose of this clinical research study is to develop observational clinical experience with the use of entecavir in participants who are either of Black/African-American race or of Hispanic ethnicity.
The purpose of this trial is to determine the safety, tolerability and effectiveness of KRN7000 for chronic hepatitis B infection.
Chronic hepatitis C may relapse in simple chronic hepatitis C patients who initially obtained sustained virologic responses. Although the HCV SVR could be maintained in around 90%, the remaining 10% of these patients may develop hepatitis C relapse during follow-up. Therefore, it is important to follow up the long-term of these patients with dual chronic hepatitis B and C. From another aspect, for the treatment of chronic hepatitis B, the virologic and serologic responses may also not be durable. Alternatively, previous studies suggested that the therapeutic efficacy might not be seen in the study period, and incremental response might occur during long-term follow-up. Therefore it is also important to clarify the long-term outcome of treatment in this dually infected population. Evaluation of the long term effects of treatment with peginterferon alfa-2a plus ribavirin for patients with chronic hepatitis C/ hepatitis B co-Infection and chronic hepatitis C in the original study ML17862 is important. This present protocol is thus to assess whether the HCV SVR is sustained and to assess the durability of the HBV virologic and serologic responses or any incremental response during a 5-year follow-up period, including six months after end of the therapy in the original study and an additional 4 and half years in this project (5 years overall follow-up after the end of treatment). Specifically, we wish to assess the (1) sustained virologic response (SVR) of HCV in both populations, (2) incidence of HBsAg loss and HBsAg seroconversion (HBsAg loss and appearance of anti-HBs) in dually infected population, (3) ALT normalization or flare off-treatment during both populations, (4) reductions of HCV RNA from the original baseline levels in the two patient populations, and (5) reduction of serum HBV DNA off-treatment in the dually infected population.
The efficacy of lamivudine in Hepatitis Be Antigen (HBeAg) positive Asian patients of chronic hepatitis has been well established.The evidence in HBeAg negative patients is limited. Limited sustained response was observed post-treatment following a one year treatment period. Whether these results can be applied to patients in Iran is uncertain. This study is therefore intended to further assess the efficacy profile after two years of open treatment in the adult Iranian population.
This 2-arm study will compare the efficacy and safety of treatment with Pegasys (180 µg weekly) plus Copegus (800 mg daily) and Pegasys (180 µg weekly) plus Copegus (1000-1200 mg daily) in interferon-naive patients with CHC genotype 1 co-infected with HIV-1. Treatment will be administered for 48 weeks, and this will be followed by 24 treatment-free weeks. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.
Phase I/II trial of KRN7000 in patients with chronic hepatitis C. Study objectives: To evaluate and compare the safety and tolerability of 3 ascending doses of a-GalCer. The primary efficacy parameter: HCV-RNA response at the end of treatment. Secondary efficacy parameter: Serum ALT response. Further objectives of the study are to evaluate the effect of a-GalCer on serum cytokines IFNg and TNFa and on iNKT cells. Number of dose levels: 3 Investigational product: KRN7000 Route of administration: intravenous Dosages and frequency: 0.1, 1, 10 mcg/kg, monthly injection, 3 times (day 0, day 28 and day 56)
The objective of this study is to better understand the influence of insulin resistance upon treatment response in hepatitis C virus treated with PEG Intron and Rebetol.
Patients with chronic hepatitis C genotype 1 virus infection are usually treated with Interferon alfa plus Ribavirin over 48 weeks. For some patients this might be too long, for others too short. An individually adapted therapy length from 24 to 72 weeks will be determined in dependence of the initial virus load and the time to HCV RNA negativity. The primary objective is to compare the cumulative rate of the sustained viral response (SVR) of the patients with the individually adapted therapy duration to the SVR rates of a historic patient collective under the 48 week standard therapy.
This 36-month open-label study of adefovir dipivoxil investigates the clinical benefits of the therapy in chronic hepatitis B patients with advanced fibrosis or cirrhosis confirmed with biopsy. Primary endpoint is histological improvement defined as a decrease of Ishak Fibrosis Score by one point or more from baseline at Month 36 of adefovir dipivoxil treatment. Approximately 150 patients will be recruited in study centres in the Asia Pacific area. The patients are offered 36 months of open label adefovir dipivoxil treatment, with assessments every three months, after which there is a 6-month post study treatment follow-up prior to study completion. After the 36 months of study treatment, it is likely that the patient will benefit from continued treatment with adefovir dipivoxil. If this is the case in the investigators clinical judgement, the investigator should ensure that a routine prescription is available in a timely manner, and that no unnecessary interruption in treatment occurs.
