About this study
Official title: Multicenter, Double-Blind, Placebo-Controlled, Randomized Phase III Study of Etanercept in the Treatment of Subjects With Ankylosing Spondylitis
This study will represent the sponsor's first controlled study of etanercept in Chinese subjects with Ankylosing Spondytitis (AS). This trial is designed to assess the safety and efficacy of etanercept compared to placebo in the treatment of patients with AS.
Read the detailed description
Multicenter, double-blind, randomized, parallel and placebo-controlled outpatient study. The study consists of 2 parts: part A is a 6-week double-blind treatment period and part B is a 6-week open-label treatment period. During part A of the study, subjects will be randomly assigned to 1 of 2 treatment regimens: 2 etanercept 25 mg or placebo once weekly, administered subcutaneously (SC). After the completion of part A, all subjects will receive 2 etanercept 25 mg once weekly. The use of placebo as a control in part A is necessary to allow a valid comparison and to provide a quantitative assessment of effect.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Enbrel (etanercept) in people with Ankylosing Spondylitis, run by Wyeth is now a wholly owned subsidiary of Pfizer.
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 3 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 Dec 2007. 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?
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?
Assessment in Ankylosing Spondylitis (ASAS) response criteria 20% at week six.. 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 13 Dec 2007.
