What is being measured

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

  1. Number of Participants With Treatment-Emergent Adverse Events (AEs) or Serious Adverse Events (SAEs)

    An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to the last participants visit in the study. The baseline data of Study A3921039, A3921040 or A3921044 were used as baseline data for safety evaluation.

Each item scored on 4-point scale, 0 to 3: 0=no difficulty; 1=some difficulty;2=much difficulty; 3=unable to do. Overall score was computed as sum of domain sc ores and divided by number of domains answered. Total possible score range 0-3: 0=least difficulty and 3=extreme difficulty.

Total score range:0 to 9.4, higher score indicated more disease activity. The baseline data of Study A3921039, A3921040 or A3921044 were used as baseline data for efficacy evaluations except for Modified Total Sharp Score (mTSS).

The score for a section is an average of the individual question scores, which are scaled 0-100 (100=highest level of functioning) and is reported as 2 summary scores; physical component score and mental component score. Total score range for the summary scores = 0-100, where higher score represents higher level of functioning. The baseline data of Study A3921039, A3921040 or A3921044 were used as baseline data for efficacy evaluations except for Modified Total Sharp Score (mTSS).

    Measured: Baseline, Weeks 12, 24, 48, 72, 96, 120, 144, 168, 192, 216, 240, 264, and 288

  21. Change From Baseline in 36-Item Short-Form Health Survey (SF-36) Component Score_Mental

    SF-36 is a standardized survey evaluating 8 aspects of functional health and well being: physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotional and mental health. The score for a section is an average of the individual question scores, which are scaled 0-100 (100=highest level of functioning) and is reported as 2 summary scores; physical component score and mental component score. Total score range for the summary scores = 0-100, where higher score represents higher level of functioning. The baseline data of Study A3921039, A3921040 or A3921044 were used as baseline data for efficacy evaluations except for Modified Total Sharp Score (mTSS).

    Measured: Baseline, Weeks 12, 24, 48, 72, 96, 120, 144, 168, 192, 216, 240, 264, and 288

  22. Change From Month 24 in Study A3921044 in Modified Total Sharp Score (mTSS)

    mTSS = sum of erosion and Joint Space Narrowing (JSN) scores for 44 joints (16 per hand and 6 per foot). mTSS scores range from 0 (normal) to 448 (worst possible total score). Change: scores at observation minus score at baseline. An increase in mTSS from baseline represented disease progression and/or joint worsening, no change represented halting of disease progression, and a decrease represented potential improvement. Month 24 (the final visit) in Study A3921044 was taken as the first visit in current study.

    Measured: First visit in the study (Month 24 in Study A3921044), Weeks 24, 48, and 96

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing CP-690,550 in people with Rheumatoid Arthritis, run by Pfizer at 56 sites in Japan.

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 1 inclusion and 1 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 May 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 56 sites in Japan. 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 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 May 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?

Number of Participants With Treatment-Emergent Adverse Events (AEs) or Serious Adverse Events (SAEs) (time frame: Baseline up to Week 288). 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 NCT00661661, which also lists 17 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 12 May 2015.
