Efficacy and Safety of Pentoxyphilline and Tocopherol on the Fibrosis in Patients With Chronic Hepatitis C - Full Text View

Purpose

The fibrosis of liver is a complication of chronic hepatitis C. There is actually no established treatment for fibrosis of the liver. Pentoxyphilline and tocopherol may have an activity on fibrosis. The aim of the study is to analyse the efficacy and the safety of the combination with pentoxyphilline and tocopherol (12 months) on liver fibrosis, in patients with chronic hepatitis C, who are non-long-term responders, or with intolerance or contra-indication to interferon-alfa and ribavirin.

Primary Outcome Measures:

Variation of the percentage of liver fibrosis evaluated with morphometric analysis between the liver biopsies performed at the end and before the trial (defined as significant if over 5 percent).

Secondary Outcome Measures:

Variation of fibrosis Metavir score between the two biopsies
Variation of activity Metavir score between the two biopsies
Variation of liver markers of fibrosis : hyaluronate, N-terminal peptide of procollagen III, TNF-alfa and fibrotest
Variation of ALT


Estimated Enrollment:	100
Study Start Date:	February 2002
Estimated Study Completion Date:	December 2006

Detailed Description:

The aim of this study is to analyse the efficacy and the safety of the combination of pentoxyphilline (400 mg, twice a day) and tocopherol (500 mg, twice a day), given during 12 months on the fibrosis related to HCV chronic hepatitis in 100 patients who are non-long-term responders, or with contra-indication or intolerance to the current treatment of reference (combination with interferon-alfa and ribavirin). It is a therapeutic, national, multicentric, double-blind, placebo-controlled phase III trial. The patients included had histological liver injuries with a Metavir score of A 0 to 2, F 2 or 3 and no other etiology of liver disease. The primary objective is to analyse the variation of the liver fibrosis evaluated by morphometric analysis between the 2 liver biopsies performed at the end of the trial and within 3 years before the treatment. The secondary objectives are the variation of the Metavir fibrosis and activity scores, of serum markers of fibrosis (hyaluronate, PIIIP, TNF-alfa, fibrotest) and ALT between the end and the beginning of the treatment.
