Gedetailleerde beschrijving

Trial enrollment was prematurely discontinued on December 3, 2007. The results of an interim efficacy and safety analysis demonstrated an overall poor tolerability profile and high discontinuation rate when dual therapy with CP-195543 and Celecoxib was administered. The decision to discontinue further enrollment in the trial was not based on any efficacy or serious safety concerns. Previously enrolled study participants continued in the study and the trial completed on February 27, 2008.

Health Assessment Questionnaire-Disability Index (HAQ-DI): participant-reported assessment of ability to perform tasks in 8 categories of daily living activities: dress/groom; arise; eat; walk; reach; grip; hygiene; and common activities over past week. Each item scored on 4-point scale from 0 to 3: 0=no difficulty; 1=some difficulty; 2=much difficulty; 3=unable to do. Overall score was computed as the sum of domain scores and divided by the number of domains answered. Total possible score range 0-3, where 0 = least difficulty and 3 = extreme difficulty.

Change From Baseline in C-Reactive Protein (CRP) at Week 1, 2, 4, 8 and 12
Tijdsspanne: Baseline, Week 1, 2, 4, 8, 12
The test for CRP is a laboratory measurement for evaluation of an acute phase reactant of inflammation through the use of an ultrasensitive assay. A decrease in the level of CRP indicates reduction in inflammation and therefore improvement.

Tijdsspanne: Baseline, Week 1, 2, 4, 8, 12
DAS28-3 (CRP) was calculated from the SJC and TJC using the 28 joints count and CRP. It was calculated as DAS28-3 (CRP) = 1.15 + 1.10 * ([0.56 * square root of TJC] + [0.28 * square root of SJC] + [0.36 * natural logarithm of {CRP+1}]). Total score range: 0 to 9.4, higher score indicated more disease activity. DAS28-3 (CRP) <= 3.2 implied low disease activity and >3.2 to 5.1 implied moderate to high disease activity, and DAS28-3 (CRP) <2.6 = remission.
Baseline, Week 1, 2, 4, 8, 12
Change From Baseline in Duration of Morning Stiffness at Week 1, 2, 4, 8 and 12
Tijdsspanne: Baseline, Week 1, 2, 4, 8, 12
Duration of morning stiffness was defined as the time elapsed between the time participant woke up and was able to resume normal activities without stiffness in hours (duration was recorded in hours to the nearest quarter.
