About this study

  • Adding Amantadine to standard anti-viral treatment can improve sustained response rates in patients with chronic hepatitis C
Read the detailed description

The CIRA-study is a double blind, placebo controlled, randomised, multicentre study in previously untreated patients suffering from chronic hepatitis C comparing double therapy, consisting of (PEG-)interferon alpha 2b ((PEG)Intron-A®) and ribavirin (Rebetol®), with triple therapy, consisting of (PEG-)interferon alpha 2b, ribavirin and amantadine, for 52 weeks. Follow-up is completed at week 104. 150 Subjects per treatment group will be included. Patients will be stratified before randomisation according to genotype (1 versus non-1). Viral load will not be a discriminating factor.

The aim is to investigate the efficacy of the adjunct amantadine to the currently used combination therapy with interferon alpha and ribavirin.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Amantadine in people with Chronic Hepatitis C, run by UMC Utrecht at 1 site in Netherlands.

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 15 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: finished, as of the sponsor's last update on 5 Sep 2005. 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 Netherlands. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Response rate at end of treatment and end of follow-up (sustained response rate). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00146016, which also lists 4 linked publications.

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 5 Sep 2005.
