About this study
Official title: Efficacy and Safety of the Association With Pentoxyphilline and Tocopherol on the Fibrosis in Patients With Chronic Hepatitis C
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.
Read the 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.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing pentoxyphilline and tocopherol in people with Hepatitis C, Chronic and Liver Fibrosis, run by French National Agency for Research on AIDS and Viral Hepatitis at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 12 Jan 2007. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early. Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
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).. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jan 2007; AzTrials last refreshed its copy on 8 Nov 2026.
