This is a Phase 3b/4, prospective, open-label, randomized, multicenter study of peginterferon alfa-2b plus ribavirin in participants with chronic hepatitis C, genotype 1. The study consists of two parts: (1) a noninterventional arm (HOMA IR <= 2) and (2) an interventional arm (HOMA IR > 2), where HOMA IR is the insulin resistance index for the participants calculated by fasting insulin (uU/mL) x [fasting glucose (mmol/L)/22.5]. Participants in the noninterventional arm are treated according to the European labeling and response rates are evaluated at Month 1 (optional), 3, 6, 12, and follow up. Participants in the interventional arm are treated with PEG-Intron 1.5 ug/kg (subcutaneous) once weekly plus weight-based REBETOL 800-1400 mg (oral capsules) daily for a variable period depending on their response at Week 12: (1) HCV-RNA positive with < 2-log drop in viral load, treatment will be discontinued; (2) HCV-RNA positive with >= 2-log drop in viral load; participants will be randomized (1:1) to Group A (stop treatment at Week 48) or Group B (stop treatment at Week 72); and (3) HCV-RNA negative, treatment will be changed to be according to the European labeling and response rates will be evaluated at Month 6, 12, and follow up. All participants will go on with their treatment after Week 12 until the results of the HCV polymerase chain reaction (PCR) are available (maximum of 4 weeks).
A Phase 2 study to evaluate safety, pharmacokinetics and efficacy of Hepatitis C Immune Globulin Intravenous (human) [Civacir(TM)] for preventing or reducing the impact of recurrent HCV infection following liver transplantation.
This single arm study will evaluate the efficacy and safety of PEGASYS in patients with lamivudine resistant HBeAg negative chronic hepatitis B. Patients will receive PEGASYS 180 micrograms s.c. weekly for 48 weeks; following this, there will be a 48 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.
This is an uncontrolled, non-randomized, open-label, multinational study designed to evaluate the efficacy and safety of PegIntron plus Rebetol in subjects with chronic hepatitis C. The study is designed to determine the proportion of chronic hepatitis C genotype 1 subjects who did not respond to previous treatment with Pegasys 180µg QW plus ribavirin, that will achieve sustained virological response (SVR) when treated with PegIntron plus Rebetol.
This study represents the first administration of GSK625433 in humans. The study is designed to evaluate initial safety and tolerability in healthy adults as well as anti-viral activity in Hepatitis C(HVC) infected adults. The way the human body processes GSK625433 will also be investigated.
This is a Phase IIIB randomized, controlled, multi-centre, open-label study of 24 versus 48 weeks therapy with Pegetron® (peginterferon alfa-2b + ribavirin) at standard doses in naïve Hepatitis C Virus (HCV) genotype 1 high viral load (HVL) participants who are Hepatitis C Virus-Ribonucleic Acid (HCV-RNA) negative at Week 4. HVL will be defined as HCV-RNA of >600,000 IU/mL prior to the initiation of therapy. Participants with genotype 1 baseline HVL prescribed Pegetron® (peginterferon and ribavirin) in the usual manner in accordance with the marketing authorization and who are viral negative at Week 4 will be randomized at Week 8 to receive a total of 24 or 48 weeks of therapy. Participants will be required to have their baseline and Week-12 viral load analyzed by the same local laboratory using the standard of care test used by the site. Qualitative testing at Week 4, 8, 16-20, 24, and 48 may be conducted either by local laboratory or a central laboratory identified by the sponsor using an assay specified by the sponsor. No additional interventions outside of the clinic's standard of care and the conditions of the Canadian product monograph for Pegetron® will be applied to participants.
To evaluate the combination of telbivudine 600 mg orally (PO) once daily and peginterferon alpha-2a 180 ug subcutaneous (sq) injection weekly for antiviral efficacy in comparison to peginterferon alpha-2a monotherapy.
In France, 50% of hepatitis C virus carriers develop chronic clinical hepatitis, which may lead to cirrhosis and liver transplantation. Transplant infection by hepatitis C virus is constant after transplantation and recurrence causes chronic liver disease in 50 to 80% of cases. The aim of this study is to assess the efficacy of cyclosporin on C virological response. Patients included in the Transpeg 1 study and non-responder or with a recurrent disease will be switched from their tacrolimus therapy to cyclosporin, in association with a 1 year peginterferon alfa-2a / ribavirin bitherapy. Efficacy will be assessed by the percentage of patients with a negative qualitative PCR after 19 months of cyclosporin treatment.
