The HAQ-DI assesses a subject's level of functional ability and includes questions of fine movements of the upper extremity, locomotor activities of the lower extremity, and activities that involve both upper and lower extremities. There are 20 questions in 8 categories of functioning including dressing, rising, eating, walking, hygiene, reach, grip and usual activities. The stem of each item asks 'Over the past week, "are you able to..." perform a particular task'. Each item is scored on a 4 point scale from 0 - 3, representing normal, no difficulty (0), some difficulty (1), much difficulty (2) and unable to do (3). The disability index score is calculated as the mean of the available category scores, ranging from 0 to 3. A negative change from baseline indicates improvement.

Participants from the full analysis set were considered for the analysis. Participants with measurements at both baseline and week 24 were analyzed. The full analysis set was comprised of all randomized participants (excluding mis-randomized participants) who were assigned to study treatment.

Separate radiographs of each hand/wrist and each foot were taken at basline and Week 24. The radiographs were assessed using the van der Heijde modified Sharp score. The change in the Van der Heijde modified Sharp score is calculated against the baseline value. The total van der Heide modified Sharp score goes from 0 to 448, the bigger the change, the worse it is for the patient.

Participants from the full analysis set were considered for the analysis. Participants with measurements at both baseline and week 24 were analyzed.

The major clinical response is defined as continuous six-month period of ACR70 response during the 1 year period. ACR70 response was defined as having a positive clinical response to treatment (individual improvement) in disease activity if the participant had at least 70% improvement in tender 68-joint count, swollen 66-joint count and at least 3 of the following 5 measures: patient's assessment of RA pain, patient's global assessment of disease activity, physician's global assessment of disease activity, subject self-assessed disability (Health Assessment Questionnaire [HAQ-DI] score), and/or acute phase reactant (high sensitivity c-reactive protein (hsCRP) or erythrocyte sedimentation rate (ESR). The ACR70 response results at week 24 used non-responder imputation.

The Full analysis set (FAS) comprised all patients who were randomized and to whom study treatment had been assigned. N=The total number of subjects in the treatment groups with evaluation

ACR20 response was defined as having a positive clinical response to treatment (individual improvement) in disease activity if the participant had at least 20% improvement in tender 68-joint count, swollen 66-joint count and at least 3 of the following 5 measures: patient's assessment of RA pain, patient's global assessment of disease activity, physician's global assessment of disease activity, subject self-assessed disability (Health Assessment Questionnaire [HAQ-DI] score), and/or acute phase reactant (high sensitivity c-reactive protein (hsCRP) or erythrocyte sedimentation rate (ESR). The ACR20 response results at week 24 used non-responder imputation.

The Full analysis set (FAS) comprised all patients who were randomized and to whom study treatment had been assigned.

The DAS28 score is a measure of RA disease activity calculated using variables such as swollen joint count, the Erythrocyte Sedimentation Rate (ESR) and patient reported assessment of health.

Using this data, the DAS28 calculation provides a number on a scale from 0-10 indicating the current activity of a patient's RA. A DAS28 score above 5.1 means high disease activity whereas a DAS28 below 3.2 indicates low disease activity. Remission is achieved by a DAS28 score lower than 2.6.

The outcome measures were not analyzed, as a result of the lack of efficacy found in study AIN457F2309 and as per changes to the planned analysis plan for CAIN457f2302/E1

Low Disease Activity is defined as DAS28 ≤ 3.2. EULAR good response requires an improvement of > 1.2 in the DAS28 score with a present score of ≤3.2; EULAR moderate response is defined as an improvement of >0.6 to ≤1.2 in DAS28 and a present score of ≤5.1; or an improvement of >1.2 and a present score of >3.2.

ACR/EULAR remission is defined as SDAI ≤ 3.3, where SDAI is a measure of disease activity in RA based on 28 tender and swollen joint counts, CRP, Physician and Patient's Global Assessments of Disease

Short Form Health Survey (SF-36) consists of eight subscales that can be scored individually: Physical Functioning, Role-Physical, Bodily Pain, General Health, Vitality, Social Functioning, Role-Emotional, and Mental Health. Two overall summary scores, the Physical Component Summary (PCS) and the Mental Component Summary (MCS) also can be computed.
