About this study

Official title: An Open-label Trial in Genotype 2, 3, 4, 5 and 6 Hepatitis C-infected Subjects to Evaluate the Antiviral Activity, Safety, Tolerability and Pharmacokinetics of TMC435350 Following 7 Days Once Daily Dosing as Monotherapy.

The purpose of this study is to assess anti-viral activity (inhibition of viral growth) of TMC435350 in genotype 2,3,4,5 and 6 hepatitis C virus infected participants who have never received treatment for their hepatitis C infection.

Read the detailed description

This is an open-label (all people know the identity of the intervention) study to assess the antiviral activity, safety, tolerability and pharmacokinetics (explores what the body does to the medication) of TMC435350 hereafter referred to as TMC435. Approximately 40 participants will be divided in 5 groups as per the genotype (8 participants each group). The study will include a screening phase (up to 6 weeks), treatment phase (7 days) and a follow-up phase (30-35 days after the last dose of study medication). Safety evaluations will include assessment of adverse events, clinical laboratory tests and cardiovascular safety.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing TMC435 in people with Hepatitis C, run by Tibotec Pharmaceuticals, Ireland at 10 sites in 3 countries.

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 4 inclusion and 4 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 28 Jul 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in Belgium, Germany, Thailand. 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?

Yes. Results are posted in the registry (first posted 28 Jul 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Change From Baseline in log10 Plasma Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) Levels (time frame: Baseline, Day 3, and Day 7). 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 28 Jul 2014.
