Hepatitis CPhase 2NCT00069511
12 Week Study of Anti-Viral Effect of Oral UT-231B in Non-cirrhotic Hepatitis C Patients who have Failed Interferon-based Therapy.
A Phase 2 study testing UT-231B in people with Hepatitis C, run by United Therapeutics at 6 sites in United States.
Trial summary
This is a multi-center study. Neither the study subjects nor the physicians will know what treatment an individual subject is receiving. Subjects will be randomly assigned (like flipping a coin) to one of five treatment groups. Read more about this study

About this study
This is a multi-center study. Neither the study subjects nor the physicians will know what treatment an individual subject is receiving. Subjects will be randomly assigned (like flipping a coin) to one of five treatment groups. The treatment groups include four different dosing groups of active study drug and one group of subjects who will receive placebo. A 12 week follow up period occurs after the 12 weeks of dosing. The study endpoint is a reduction in Hepatitis C viral load.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing UT-231B in people with Hepatitis C, run by United Therapeutics at 6 sites in United States.
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 3 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 24 Jun 2005. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 6 sites in United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00069511, which also lists 14 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 24 Jun 2005; AzTrials last refreshed its copy on 8 Nov 2026.
