Outcomes

Primary Outcome Measures

Percentage of Participants by Anti-Drug Antibody (ADA) Status Using Anti-PF-05280586 Antibody Assay
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
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.

Sixty-eight joints were assessed by a blinded joint assessor to determine the number of joints that were considered tender or painful. For consistency, a single assessor was preferred to perform all evaluations across the study for an individual participant. The response to pressure/motion on each joint was assessed using the following scale: Present/Absent/Not Done/Not Applicable (to be used for artificial or missing joints).

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
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.

Outcome Measure Using HAQ-DI - by the End of 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 outcome reported in the table is mean HAQ-DI score at each time point, and it is on the scale of HAQ-DI score with the range from 0 to 3.

Sixty-six joints were assessed by a blinded joint assessor for swelling. For consistency, a single assessor was preferred to perform all evaluations across the study for an individual participant. The response was assessed using the following scale: Present/Absent/Not Done/Not Applicable (to be used for artificial or missing joints). Artificial joints were not be assessed.
Time Frame
Screening, Week 1, 6, 13, and 25 (Course 1 and Course 2).

Title
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
Description
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.
Time Frame
Week 1, 6, 13, and 25 (Course 1).
