Increasing Cure Rate of Hepatitis C Therapy in Obese Hepatitis C Patients - Full Text View

Sponsor:	University of Pittsburgh
Information provided by:	University of Pittsburgh
ClinicalTrials.gov Identifier:	NCT00871845

Purpose

The purpose of this study is to determine whether obese people do not respond to hepatitis C treatment as well as lean people. This research studies whether obese people will show higher sustained virologic response rate if they lose weight by Orlistat use and dietary and lifestyle modification.

Arms	Assigned Interventions
1) non obese, naive: No Intervention Patients naive to hepatitis C therapy with body mass index (BMI) <25
2) obese, naive, control: No Intervention Patients naive to hepatitis C therapy with BMI ≥ 30
3) obese, naive, orlistat: Active Comparator Patients naive to hepatitis C therapy with BMI ≥ 30 as an interventional group, patients will receive up to 6 sessions of dietary and physical education after which they will start receiving their standard hepatitis C treatment. they will be encouraged to attend up to 12 monthly meetings (along side the monthly visits for their standard viral hepatitis therapy) at the health education room of center for liver diseases, to check dietary diaries. The dietary and physical education (given through up to 6 weekly sessions and subsequently up to 12 monthly follow-up meetings) will be presented. Orlistat (60 mg capsules, three times daily, before meals) will be prescribed for a time frame starting 3 to 6 weeks prior to and during the 48 weeks of the standard anti-viral therapy.	Drug: Orlistat Orlistat 60 mg capsules, three times daily, before meals) will be prescribed for a time frame starting 3 to 6 weeks prior to and during the 48 weeks of the standard anti-HCV therapy.
4) obese, naive, Placebo: Placebo Comparator Patients naive to hepatitis C therapy with BMI ≥ 30 as an interventional group, patients will receive up to 6 sessions of dietary and physical education after which they will start receiving their standard hepatitis C treatment. they will be encouraged to attend up to 12 monthly meetings (along side the monthly visits for their standard viral hepatitis therapy) at the health education room of center for liver diseases, to check dietary diaries. The dietary and physical education (given through up to 6 weekly sessions and subsequently up to 12 monthly follow-up meetings) will be presented. Placebo will be prescribed for a time frame starting 3 to 6 weeks prior to and during the 48 weeks of the standard anti-viral therapy.	Behavioral: Dietary and Lifestyle modification educational sessions 6 sessions of dietary and physical education after which they will start receiving their standard hepatitis C treatment. they will be encouraged to attend up to 12 monthly meetings (along side the monthly visits for their standard viral hepatitis therapy.
5) obese, non-naive, orlistat: Active Comparator Patients non responder or relapser after previous course of Hepatitis C therapy, with BMI ≥ 25. Patients will receive up to 6 sessions of dietary and physical education after which they will start receiving their standard hepatitis C treatment. they will be encouraged to attend up to 12 monthly meetings (along side the monthly visits for their standard viral hepatitis therapy. The dietary and physical education. Orlistat 60 mg capsules, three times daily, before meals) will be prescribed for a time frame starting 3 to 6 weeks prior to and during the 48 weeks of the standard anti-viral therapy.	Drug: Orlistat Orlistat 60 mg capsules, three times daily, before meals) will be prescribed for a time frame starting 3 to 6 weeks prior to and during the 48 weeks of the standard anti-HCV therapy.
6) obese, non-naive, Placebo: Placebo Comparator Patients naive to hepatitis C therapy with BMI ≥ 30 as an interventional group, patients will receive up to 6 sessions of dietary and physical education after which they will start receiving their standard hepatitis C treatment. they will be encouraged to attend up to 12 monthly meetings (along side the monthly visits for their standard viral hepatitis therapy) at the health education room of center for liver diseases, to check dietary diaries. The dietary and physical education (given through up to 6 weekly sessions and subsequently up to 12 monthly follow-up meetings) will be presented. Placebo will be prescribed for a time frame starting 3 to 6 weeks prior to and during the 48 weeks of the standard anti-viral therapy.
