Filter by:A Phase 3 study to evaluate the efficacy and safety of two dosing regimens of telaprevir in combination with pegylated interferon alfa 2a (Peg-IFN-alfa-2a) and ribavirin (RBV).
For chronic hepatitis C patients unresponsive to previous (PEG-)IFN/RBV combination therapy we propose continuous subcutaneous administration of high-dose IFN-a2b (Intron A®) for 48 weeks in combination with 15 mg/kg/day RBV (Rebetol®) and optimal management of side effects in order to maintain the highest possible dosages of both IFN-a2b and RBV for 48 weeks. We expect improved tolerability with continuous subcutaneous pump delivery of IFN-a2b compared to thrice weekly or daily subcutaneous injection of IFN-a2b, and increased antiviral activity and biologic potency due to sustained and higher levels of a fully potent interferon protein.
This study will evaluate the efficacy and safety of peginterferon alfa-2a 40KD + ribavirin combination therapy given for 24 weeks versus 48 weeks in patients with chronic hepatitis C, genotype 2/3.
Safety: To describe the safety profiles following vaccination. Immunogenicity: To describe the immune response after a single dose of vaccine.
The purpose of this study is to assess the efficacy and safety after administration of MP-424 to patients with chronic hepatitis C.
This 3 arm study will assess the efficacy and safety of PEGASYS + entecavir combination therapy in treatment-naive patients with HBeAg positive chronic hepatitis B. Patients will be randomized to receive 1)PEGASYS 180 micrograms s.c./week for 48 weeks, 2)PEGASYS 180 micrograms s.c./week for 48 weeks + entecavir 0.5mg p.o. once daily from week 13 to week 36 or 3) entecavir 0.5mg p.o. once daily for 24 weeks + PEGASYS 180 micrograms s.c./week from week 21 to 68. Treatment will be followed by 24 weeks treatment-free follow up. The anticipated time on study treatment is 3-12 months for groups 1 and 2, and 1-2 years for group 3, and the target sample size is 100-500 individuals.
This randomized clinical trial will examine the effectiveness of a strategy of HIV and Hepatitis Care Coordination (HCC) consisting of testing, education, counseling and vaccination for methadone maintenance patients compared with standard Testing, Education, and Counseling (TEC).
The main objective of this study is to assess whether a recently-developed bioassay for the protein FGL2 can be used to predict the progression and/or response to treatment of Hepatitis C Virus disease in patients with chronic HCV infection. The hypothesis is that increased levels of FGL2 and increased numbers of T regulatory cells are associated with a failure to respond to treatment.
The GI-5005 therapeutic vaccine in combination with standard of care or standard of care alone will be injected under the skin of HCV subjects. Patients will be monitored for safety, immune responses and any therapeutic benefits related to the injections including EVR, ETR, and SVR.
This protocol posting describes the booster phase of the study. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT number = NCT00289731).
