Chronic Hepatitis C Infection
Drug: Rosiglitazone and Pegasys/Ribavirin
|Study Design:||Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Primary Purpose: Treatment
|Official Title:||Randomized Placebo-Control Pilot Study Evaluating the Efficacy and Safety of Rosiglitazone Combined With Pegylated Interferon Plus Ribavirin Versus Pegylated Interferon Plus Ribavirin Alone in Genotype 1 Hepatitis C With Steatosis|
- To compare the efficacy of Rosiglitazone in combination with pegylated interferon alfa-2a and ribavirin (weight-based) to that of pegylated interferon alfa-2a and ribavirin alone in terms of sustained viral response.
- To compare the safety and tolerability of Rosiglitazone in combination with pegylated interferon-2a and ribavirin to that of pegylated interferon alfa-2a and ribavirin alone in terms of adverse events.

Eligible thirty subjects will be randomized in a double blinded fashion to either Rosiglitazone 4mg pills twice a day versus placebo for six weeks. Then after this six week period, both groups will be treated for 48 weeks of standard therapy for hepatitis C consisting of Pegasys 180mcq weekly injections with Ribavirin 1,000mg-1,200mg daily depending if the subject weights less than 75 kg will then receive the lower dosage. In addition, the subjects will be continued on Rosiglitazone or placebo for the 48 weeks.
The subjects will be monitored for side-effects by history taking and blood testing at predetermined time periods during the study. If the viral load has not dropped more than two log at week 12 of standard therapy for hepatitis C then therapy will be stopped and the subject is considered a treatment failure. Similarly, if there was a greater than two log drop in the viral load at week 12 but there is still virus present in the blood at week 24 then therapy is stopped and the subject is considered treatment failure. If the virus is undetectable in the blood at week 12 and 24 then therapy is continued for the full 48 weeks. If the virus is detectable at week 48 then the subject is considered a treatment failure.
After this 48 week treatment period and the virus is still undetectable, there is a follow-up period consisting of 24 weeks off therapy. At the end of the 24 weeks, blood will be tested for the virus and if the virus is not present then the subject has a sustained viral response and is a treatment success.
During therapy if the subject becomes significantly anemic Procrit 40,000Units weekly injections will be started. Similarly, if the white blood cell count drops below a certain level then weekly Neupogen 300mcq injections will be started. In addition, if there is mild depressive symptoms treatment will be started but if there is major depressive symptoms, then therapy will be stopped and a referral to a psychiatrist will be made.
