What is being measured

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

  1. Psoriasis Area and Severity Index (PASI) 75 Response Rate at Week 10

    PASI correlates to the physician's assessment of psoriasis symptoms including redness of lesions, thickness of lesions, scaliness of lesions and extent of disease. Each parameter is graded from 0-4, 0 refers to no disease and 4 to severe involvement. The body is divided into 4 areas for scoring (head, arms, trunk to groin, legs to top of buttocks), and the final score ranges from 0-72. The PASI 75 response rate at Week 10 is measured as the percentage of participants who achieved at least 75% improvement from baseline PASI at Week 10.

  12. Percent Reduction in Self-Administered Psoriasis Area Severity Index (SAPASI) at Week 18

    SAPASI is the participant's measurement of severity of psoriasis. The participant estimates the area of psoriatic involvement for each body district (head, upper limbs, trunk and lower limbs) and scores it from 0 (no involvement)-6 (90-100% involvement); and the extent of psoriasis from 0 (no involvement) to 4 (very marked) for each - erythema, desquamation and induration of the plaques. The final score computed by the investigator ranged from 0-72. The percent reduction in SAPASI at Week 18 compared to baseline is reported.

    Measured: Baseline and Week 18

  13. Percent Reduction in SAPASI at Week 24

    SAPASI is the participant's measurement of severity of psoriasis. The participant estimates the area of psoriatic involvement for each body district (head, upper limbs, trunk and lower limbs) and scores it from 0 (no involvement)-6 (90-100% involvement); and the extent of psoriasis from 0 (no involvement) to 4 (very marked) for each - erythema, desquamation and induration of the plaques.

    Measured: Baseline and Week 24

  14. Percent Reduction in Affected Body Surface Area (BSA) at Week 18

    The BSA is the physician's evaluation for the extent of disease. The entire body area is divided into 4 districts: head, upper limbs, trunk and lower limbs to which corresponds the 10%, 20%, 30% and 40% of the entire body surface respectively. The investigator assesses the percentage of the participant's body surface area affected by psoriasis in each district. The final affected BSA value is the sum of the percentage of each district. The percent reduction in affected BSA at Week 18 compared to baseline is reported.

    Measured: Baseline and Week 18

  15. Percent Reduction in Affected BSA at Week 24

Participants answered 29 questions referring to the previous 4-week period, on a 5-point scale from "never" (=0) to "all the time" (=4). The score for each scale ranges from 0 to 100 and higher scores reflect a worse quality of life. The percent reduction in SKINDEX-29 scores at Week 18 compared to baseline is reported.

    Measured: Baseline and Week 18

  21. Percent Reduction in SKINDEX-29 Scores at Week 24

    The SKINDEX-29 measures the quality of life in dermatological participants, who complete a questionnaire assessing 3 scales - burden of symptoms, social functioning and emotional state. Participants answered 29 questions referring to the previous 4-week period, on a 5-point scale from "never" (=0) to "all the time" (=4). The score for each scale ranges from 0 to 100 and higher scores reflect a worse quality of life. The percent reduction in SKINDEX-29 scores at Week 24 compared to baseline is reported.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Infliximab in people with Psoriasis, 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 12 inclusion and 26 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 9 Aug 2023. 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 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 24 Feb 2011). 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?

Psoriasis Area and Severity Index (PASI) 75 Response Rate at Week 10 (time frame: Baseline and 10 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 NCT00686595, 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 9 Aug 2023.
