Serum samples were collected to determine the presence of ADA using two validated assays, one specific for PF-05280586 and one specific for the licensed drug products.
For participants assigned to PF-05280586 in Study B3281001, blood samples were screened for ADA using the assay specific to PF-05280586; if the blood samples were confirmed to be positive (+ve) for ADA against PF-05280586, the samples were also analyzed using the assay specific for the licensed drug products to assess cross-reactivity of the ADA.
For participants assigned to the licensed products in Study B3281001, blood samples were screened for ADA using both assays in order to assess any product-specific ADA and/or cross-reactivity for the transition from the licensed products to PF-05280586.

Mean Change From Initial Study Baseline in Disease Activity Score (DAS28)-C-Reactive Protein (CRP) - by the End of Course 1
Time Frame: Baseline B3281001, Week 1, 6, 13, and 25 (Course 1).
|
The disease activity score (DAS) assessment is a continuous composite measure derived using differential weighting given to the following 4 components: tender/painful joint count (28 joints), swollen joint count (28 joints), CRP and patient's global assessment of arthritis Visual Analog Scale (VAS).
The formula for calculation of DAS28-CRP from these 4 components is DAS28-CRP equals (=) 0.56 square root (sqrt) (DAS 28 tender joint count) + 0.28 sqrt (DAS 28 swollen joint count) + 0.36 natural log [ln] (CRP [milligrams per liter, mg/L] +1) + 0.014 (global assessment of health [GH]) + 0.96.
Total score range: 0 to 9.4, higher score indicated more disease activity.

The DAS assessment is a continuous composite measure derived using differential weighting given to the following 4 components: tender/painful joint count (28 joints), swollen joint count (28 joints), CRP and patient's global assessment of arthritis VAS.
The formula for calculation of DAS28-CRP from these 4 components is DAS28-CRP = 0.56 sqrt (DAS 28 tender joint count) + 0.28 sqrt (DAS 28 swollen joint count) + 0.36 (ln CRP [mg/L] +1) + 0.014 (GH) + 0.96.
Total score range: 0 to 9.4, higher score indicated more disease activity.
DAS28-CRP <2.6 implied remission.

Percent Change From Initial Study Baseline in Individual Components of the ACR Response: Health Assessment Questionnaire - Disability Index (HAQ-DI) - by the End of Course 1
Time Frame: Week 1, 6, 13, and 25 (Course 1).
|
HAQ-DI assessed the degree of difficulty participants experienced in 8 daily living activity domains during a week: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and other activities. Each activity category consisted of 2-3 items. Each question's difficulty was scored from 0-3 (0=no difficulty, 1=some difficulty, 2=much difficulty, 3=unable to do). Activities requiring assistance (from people or assistive devices) were adjusted to ≥2 to denote more limited functional status. The questionnaire was to be completed by the participant prior to any procedures during the visit, if possible. Overall HAQ-DI score was computed as the sum of domain scores divided by the number of domains answered, providing a score from 0-3. Low scores denoted improvement of disability/lower degree of domain difficulty. Primary outcomes reported post baseline mean percent (%) changes in HAQ-DI score. Post baseline values are reported on the % change from initial study Baseline scale. |
