What is being measured
The primary outcome is the main question the study is designed to answer.
To compare the efficacy of etanercept (25 mg, twice weekly) with that of placebo based on the
percentage of patients who achieved the assessment in Ankylosing Spondylitis (ASAS 20%) response criteria at week 12.
Secondary outcomes (2)
To assess: 1) the safety of etanercept in this patient population; 2) the efficacy of etanercept
compared with that of placebo using the ASAS response criteria at 50% and 70% levels at week 12.

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?
To compare the efficacy of etanercept (25 mg, twice weekly) with that of placebo based on the. The study lists 2 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 NCT00421915, which also lists 2 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?
