| Study group | Role | What they receive |
|---|---|---|
| A | Active comparator | Period 1 (Double Blind): 50mg bi-weekly (BIW) for weeks 1-12. Period 2 (Open Label): 50 mg weekly (QW). Receives: Drug: etanercept |
| B | Active comparator | Period 1 (Double Blind): 50mg weekly (QW) with matching placebo for weeks 1-12. Period 2 (Open Label): 50 mg weekly (QW) for weeks 13-24. Receives: Drug: etanercept; Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Patients Achieving "Clear" or "Almost Clear" on Physician Global Assessment (PGA) of Psoriasis
The PGA of Psoriasis scale ranges from 0 (no psoriasis) to 5 (severe disease). "Clear" and "Almost Clear" includes all patients who were scored as a 0 or 1.
Measured: 12 weeks
Secondary outcomes (1)
Number of Patients Achieving Psoriatic Arthritis Response Criteria (PsARC)
The PsARC response was defined as improvement in at least 2 of the four criteria: >=30% decrease in swollen joint count, >=30% decrease in tender joint count, >=20% improvement in patient's Global Assessment of Disease Activity (arthritis) using VAS (0-100 mm, 0=excellent and 100= poor), >=20% improvement in physician's Global Assessment of Disease Activity using VAS (VAS: 0-100 mm, 0=no arthritis activity and 100=extremely active arthritis), and at least one of the 2 joint criteria with no deterioration in the other criteria.
Measured: 12 and 24 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing etanercept in people with Psoriatic Arthritis, run by Wyeth is now a wholly owned subsidiary of Pfizer at 120 sites in 26 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 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 31 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 120 sites in Germany, France, United Kingdom, Italy, Argentina and 21 more countries. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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 27 May 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 Patients Achieving "Clear" or "Almost Clear" on Physician Global Assessment (PGA) of Psoriasis (time frame: 12 weeks). 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 NCT00245960, which also lists 6 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 31 Jan 2022.
