Trial summary
The primary objective of the study is to demonstrate that the efficacy of peginterferon alfa-2a 40KD combination therapy with ribavirin in interferon naïve patients with chronic hepatitis C virus infection genotype 2 or 3 given for 12 weeks is non-inferior to 24 weeks. Read more about this study

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Peginterferon alfa-2a 40KD and Ribavirin in people with Hepatitis C Virus, run by NORDynamIC Study Group at 1 site in Sweden.
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 10 inclusion and 21 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 7 Apr 2008. 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 Sweden. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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?
Sustained Viral Response (SVR) rate defined as percentage of patients with non-detectable HCV-RNA as measured by COBAS TaqMan 48™ (<50 IU/mL) at 24 weeks post completion of the 12 or 24 week treatment period.. 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 NCT00143000, which also lists 1 linked publication.
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 7 Apr 2008.
