What is being measured

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

  1. The Percentage of Subjects Achieving American College of Rheumatology (ACR) 20 Improvement

    The ACR 20 is defined as ≥ 20% improvement in tender joint count plus ≥ 20% improvement in swollen joint count plus ≥ 20% improvement in 3 of the following 5 criteria: subject's assessment of pain, Subject's global assessment of disease activity (PGA), Physician's global assessment of disease activity (PHGA), subject's self-assessed disability Health Assessment Questionnaire (HAQ), and Erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP), whichever shows the greatest change.

    Measured: Day 28

Secondary outcomes (8)
  1. The Percentage of Subjects Achieving ACR 50 Improvement

    The ACR 50 is defined as ≥ 50% improvement in tender joint count plus ≥ 50% improvement in swollen joint count plus ≥50% improvement in 3 of the following 5 criteria: subject's assessment of pain, PGA, PHGA, subject's self-assessed disability HAQ, and ESR or CRP, whichever shows the greatest change.

    Measured: Day 28

  2. The Percentage of Subjects Achieving ACR 70 Improvement

    The ACR 70 is defined as ≥ 70% improvement in tender joint count plus

    ≥ 70% improvement in swollen joint count plus ≥ 70% improvement in 3 of the following 5 criteria: subject's assessment of pain, PGA, PHGA, subject's self-assessed disability HAQ, and ESR or CRP, whichever shows the greatest change.

    Measured: Day 28

  3. Change From Baseline in Disease Activity Score 28 (DAS 28) ESR Score

    Calculation of the disease activity score 28 (DAS 28) score was based on the tender joint count, plus swollen joint count, plus PGA, plus Erythrocyte sedimentation rate (ESR). The DAS28-ESR is expressed as units on a scale with the minimum score=0 (best) to maximum score=10 (worst). Remission was defined as DAS28-ESR <2.6. The mean change from baseline (which represent decreases in the DAS 28 ESR scores) are shown as positive numbers in these analyses.

    Measured: Baseline, Day 28

  4. Change From Baseline in Disease Activity Score 28 (DAS 28) CRP Score

    Calculation of the disease activity score 28 (DAS 28) score was based on the tender joint count, plus swollen joint count, plus PGA, plus C-reactive protein (CRP). A higher score indicated more disease activity. The mean change from baseline (which represent decreases in the DAS 28 CRP scores) are shown as positive numbers in these analyses. The DAS28 provides a score on a scale from 0 to 10 indicating the current activity of the rheumatoid arthritis (>5.1=high disease activity; <3.2=low disease activity; <2.6=remission).

    Measured: Baseline, Day 28

  5. Percentage of Subjects Who Achieved DAS 28 ESR Low Disease

    Subjects who achieved low disease activity based on the DAS 28 ESR (score <3.2). Subjects who achieved low disease activity were classified as responders in this analysis.

    Measured: Day 28

  6. Percentage of Subjects Who Achieved DAS 28 CRP Low Disease

    Subjects who achieved low disease activity based on the DAS 28 CRP (score <3.2). Subjects who achieved low disease activity were classified as responders in this analysis.

    Measured: Day 28

  7. Percentage of Subjects Who Achieved DAS 28 ESR Inactive Disease

    Subjects who achieved inactive disease based on the DAS 28 ESR (score <2.6). Subjects who achieved low disease activity were classified as responders in this analysis.

    Measured: Day 28

  8. Percentage of Subjects Who Achieved DAS 28 CRP Inactive Disease

    Subjects who achieved inactive disease based on DAS 28 CRP (score <2.6). Subjects who achieved low disease activity were classified as responders in this analysis.

    Measured: Day 28

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing INCB018424 in people with Rheumatoid Arthritis, run by Incyte Corporation at 15 sites in 2 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 2 inclusion and 5 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 23 Mar 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in United States, Poland. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 23 Mar 2015). 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?

The Percentage of Subjects Achieving American College of Rheumatology (ACR) 20 Improvement (time frame: Day 28). 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 23 Mar 2015.
