What is being measured

The primary outcome is the main question the study is designed to answer.

  1. PASI 75 Response at Week 24

    Percentage of participants achieving at least a 75% decrease (improvement) from Baseline in the Psoriasis Area and Severity Index (PASI) at Week 24. PASI Score incorporates measures of erythema, desquamation, infiltration, and affected body surface area. Involvement and severity of psoriasis was scored by a blinded assessor using a scale of 0 to 72, where 0 = no psoriasis and 72 = severe disease.

    Measured: Baseline and 24 Weeks

Secondary outcomes (9)
  1. PASI 50 Response at Week 24

    Percentage of participants achieving at least a 50% decrease (improvement) from Baseline in the Psoriasis Area and Severity Index (PASI) at Week 24. PASI Score incorporates measures of erythema, desquamation, infiltration, and affected body surface area. Involvement and severity of psoriasis was scored by a blinded assessor using a scale of 0 to 72, where 0 = no psoriasis and 72 = severe disease.

    Measured: Baseline and 24 Weeks

  2. Static Physician Global Assessment (sPGA) Response at Week 24

    Percentage of participants achieving a clear (0) or almost clear (1) status on the Static Physician Global Assessment (sPGA) at Week 24. This index evaluates the physician's global assessment of the participant's psoriasis based on severity of induration, scaling, and erythema. The assessment was scored by a blinded assessor on a scale of 0 to 5, where 0 = clear, with no evidence of plaque elevation, erythema, or scale, and 5 = severe induration, erythema, and scaling.

    Measured: Week 24

  3. PASI 50 Response at Week 12

    Percentage of participants achieving at least a 50% decrease (improvement) from Baseline in the Psoriasis Area and Severity Index (PASI) at Week 12. PASI Score incorporates measures of erythema, desquamation, infiltration, and affected body surface area. Involvement and severity of psoriasis was scored by a blinded assessor using a scale of 0 to 72, where 0 = no psoriasis and 72 = severe disease.

    Measured: Baseline and 12 Weeks

  4. PASI 75 Response at Week 12

    Percentage of participants achieving at least a 75% decrease (i.e. improvement) from Baseline in the Psoriasis Area and Severity Index (PASI) at Week 12. PASI Score incorporates measures of erythema, desquamation, infiltration, and affected body surface area. Involvement and severity of psoriasis was scored by a blinded assessor using a scale of 0 to 72, where 0 = no psoriasis and 72 = severe disease.

    Measured: Baseline and 12 Weeks

  5. Static Physician Global Assessment (sPGA) Response at Week 12

    Percentage of participants achieving a clear (0) or almost clear (1) status on the Static Physician Global Assessment (sPGA) at Week 12. This index evaluates the physician's global assessment of the participant's psoriasis based on severity of induration, scaling, and erythema. The assessment was scored by a blinded assessor on a scale of 0 to 5, where 0 = clear, with no evidence of plaque elevation, erythema, or scale, and 5 = severe induration, erythema, and scaling.

    Measured: Week 12

  6. PASI 90 Response at Week 12

    Percentage of participants achieving at least a 90% decrease (improvement) from Baseline in the Psoriasis Area and Severity Index (PASI) at Week 12. PASI Score incorporates measures of erythema, desquamation, infiltration, and affected body surface area. Involvement and severity of psoriasis was scored by a blinded assessor using a scale of 0 to 72, where 0 = no psoriasis and 72 = severe disease.

    Measured: Baseline and 12 Weeks

  7. PASI 90 Response at Week 24

    Percentage of participants achieving at least a 90% decrese (improvement) from Baseline in the Psoriasis Area and Severity Index (PASI) at Week 24. PASI Score incorporates measures of erythema, desquamation, infiltration, and affected body surface area. Involvement and severity of psoriasis was scored by a blinded assessor using a scale of 0 to 72, where 0 = no psoriasis and 72 = severe disease.

    Measured: Baseline and 24 Weeks

  8. Change From Baseline in the Percentage of Body Surface Area Involved With Psoriasis at Week 12

    A measurement of psoriasis involvement, given as the physician's assessment of the percentage of the participant's total body surface area (BSA) involved with psoriasis. The BSA numerical score was completed by a blinded assessor. A decrease from Baseline indicates improvement. Change from Baseline was calculated as Baseline score - Week 12 score; a positive change from Baseline therefore indicates improvement.

    Measured: Baseline and 12 Weeks

  9. Change Form Baseline in Percentage of Body Surface Area Involved With Psoriasis at Week 24

    A measurement of psoriasis involvement, given as the physician's assessment of the percentage of the participant's total body surface area (BSA) involved with psoriasis. The BSA numerical score was completed by a blinded assessor. A decrease from Baseline indicates improvement. Change from Baseline was calculated as Baseline score - Week 24 score; a positive change from Baseline therefore indicates improvement.

    Measured: Baseline and 24 Weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Methotrexate and Etanercept in people with Psoriasis, run by Amgen.

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 12 inclusion and 61 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 12 Aug 2013. 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 12 Aug 2013). 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?

PASI 75 Response at Week 24 (time frame: Baseline and 24 Weeks). 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 12 Aug 2013.
