This is a prospective, multi-center, randomized, placebo-controlled trial in subjects with histological evidence of >33% hepatic steatosis or NASH and chronic hepatitis C. Patients who have not been previously treated for hepatitis C (treatment naïve) will be enrolled

Official title: A Multi-Centered, Prospective, Randomized, Placebo-Controlled Clinical Trial for the Treatment of Significant Steatosis or NASH With Xenical Followed by Treatment of Hepatitis C (HCV) With PEG-Interferon Alpha-2a/Copegus

Study design: Treatment, Randomized, Double-Blind, Placebo Control, Parallel Assignment, Safety/Efficacy Study

Primary outcome: Sustained virological response (SVR) defined as the percentage of participants with undetectable HCV-RNA as measured by the Roche AMPLICORTM HCV Test, v 2.0 (detection limit  50 IU/mL) at 24 weeks post completion of the treatment period

Secondary outcome: Hepatic steatosis, necroinflammatory activity and fibrosis improvement at week 36 as determined by Dr. Elizabeth Brunt at Saint Louis University

Detailed description: Recent evidence suggests that patients with concomitant chronic HCV infection and NASH or significant hepatic steatosis (>33%) respond less well to standard antiviral therapy. As previously noted, up to 10% of patients with chronic HCV infection will have concomitant NASH and an even greater percentage will have associated hepatic steatosis. No prospective studies to date have evaluated the sustained viral response rates to standard antiviral therapy in this group of patients who were previously treated with a medication to eliminate or improve the underlying NASH and/or hepatic steatosis.

Primary Outcome: To determine if decreasing the amount of NASH or hepatic steatosis in overweight (BMI >27 kg/m2) HCV patients results in improved overall SVR to PEGASYS and Copegus.

Secondary Outcome: 1. To determine the amount of steatosis, necroinflammatory activity, and fibrosis change in a group of participants with chronic hepatitis C and NASH or significant steatosis treated with Xenical vs. placebo for 36 weeks. 2. To assess for a difference in insulin resistance, as measured by the QUICKI score, before and after treatment with Xenical or Xenical placebo and diet and exercise.

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

criteria at the Enrollment Visit (WNL = within normal limits):

potential are practicing adequate contraception method, or monogamous relationship with a male partner who has had a vasectomy or is using a condom + spermicide) during the treatment period and for six months following the last dose of study medication

- Reconfirmation that sexually active male subjects are practicing two acceptable

methods of contraception

Exclusion Criteria:

- Women who are pregnant or breast-feeding

- Males whose female partner is pregnant

- No other Thiazolidinedione after liver biopsy and/or during the entire study

- Hepatitis C of non-genotype 1,2,3 or 4

- Previous anti-viral therapy for treatment of Hepatitis C

steatosis, including but not limited to: Hemochromatosis,Alpha-1 antitrypsin deficiency, Co-infection with HBV, Wilson’s disease, Autoimmune hepatitis, Alcoholic liver disease, Drug-related liver disease

- Any condition that would prevent the subject from having a liver biopsy

- Hemoglobinopathies (e. g. Beta Thalassemia)

- Evidence of advanced liver disease

- Patients with organ transplants other than cornea and hair transplant

- Any known preexisting medical condition that could interfere with the subject’s

participation in and completion of the protocol such as: Preexisting psychiatric condition, especially severe depression, or a history of severe psychiatric disorder, such as major psychoses, suicidal ideation and/or suicidal attempt are excluded, CNS trauma or preexisting/active seizure disorders uncontrolled with medication, Significant cardiovascular dysfunction within the past 12 months, Poorly controlled diabetes mellitus, Chronic pulmonary disease with documented pulmonary hypertension, Immunologically mediated disease (Crohn’s disease, ulcerative colitis), rheumatoid arthritis, idiopathic thrombocytopenia purpura, systemic lupus erythematosus, autoimmune hemolytic anemia, scleroderma, severe psoriasis, clinical cryoglobulinemia with vasculitis
