About this study

Official title: A Placebo-controlled, Double-blinded, Randomized Clinical Trial of Anti-TNF Chimeric Monoclonal Antibody (cA2) in Korean Patients With Active Rheumatoid Arthritis Despite Methotrexate Treatment (Open-label Extension Part)

This trial is extension part of the P04280 (placebo-controlled, double-blind, randomized study of chronic treatment with infliximab in approximately 140 patients, NCT00202852). This study will be conducted at 6 study centers in South Korea. After completion of the last follow-up visit at Week 30 and code break in main double-blind trial, subjects randomized to the placebo group and those who were treated with an infliximab-containing regimen who maintained clinical response at the time of study completion will be provided with open-label infliximab for treatment of their conditions and additional safety data will be collected.

Being tested
Infliximab + methotrexate (MTX)
Medical subject headings
Arthritis, Rheumatoid

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Infliximab + methotrexate (MTX) in people with Arthritis, Rheumatoid, run by Merck Sharp & Dohme LLC.

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 27 inclusion and 24 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 13 Apr 2017. Status can change between updates, so confirm with the study contact before making plans.

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?

Yes. Results are posted in the registry (first posted 21 Jul 2009). 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?

Number of Subjects Experiencing Any Adverse Event (time frame: throughout entire study (61 +/- 28.9 weeks on average)). The study lists 3 primary outcomes in all. 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 NCT00732875, 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 13 Apr 2017.
