Percentage of Participants Achieving a Total Fingernail Modified Nail Psoriasis Severity Index (mNAPSI) 75 Response at Week 26
Week 26

Each fingernail was assessed for psoriasis with mNAPSI, and the scores of all 10 fingernails were combined. Investigators assessed each nail abnormality for each of a participant's nails by grading 3 features or groups of features (pitting, onycholysis and oil-drop dyschromia, and crumbling) and noting the presence or absence of 4 features (leukonychia, splinter hemorrhages, hyperkeratosis, and red spots in the lunula). The range of possible scores was 0 to 130, with a score of 0 indicating absence of nail psoriasis and a score of 130 indicating the most severe nail psoriasis. A decrease in mNAPSI score indicates improvement. The mNAPSI 75 response is defined as at least 75% reduction from baseline in mNAPSI.

Mean Change From Baseline in Health Assessment Questionnaire (HAQ-DI) at Weeks 36 and 48
Baseline (Study NCT01712178 Week 0 Visit), Weeks 36 and 48

The Health Assessment Questionnaire - Disability Index (HAQ-DI) is a patient-reported questionnaire specific for rheumatoid arthritis. It consists of 20 questions referring to eight domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and daily activities. Participants assessed their ability to do each task over the past week using the following response categories: without any difficulty (0); with some difficulty (1); with much difficulty (2); and unable to do (3). Scores on each task were summed and averaged to provide an overall score ranging from 0 to 3, where zero represents no disability and three very severe, high-dependency disability. The minimal clinically important difference (MCID) defined for the HAQ-DI is 0.22. HAQ remission indicating normal physical function is defined by HAQ-DI \< 0.5.

Serum Concentrations of Adalimumab at Weeks 12 and 24
Measured at Weeks 12 and 24

Blood samples for adalimumab analysis were collected by venipuncture and serum concentrations of adalimumab were determined using a validated enzyme-linked immunoadsorbent assay (ELISA) method.

Mean Disease Activity Scores (DAS28) at Weeks 12 and 24
Measured at Weeks 12 and 24

The Disease Activity Score (DAS28) is a validated index of rheumatoid arthritis disease activity. Twenty-eight tender joint counts, 28 swollen joint counts, C-reactive protein, and general health are included in the DAS28 score. Scores on the DAS28 range from 0 to 10. A DAS28 score \>5.1 indicates high disease activity, a DAS28 score \<3.2 indicates low disease activity, and a DAS28 score \<2.6 indicates clinical remission.

Mean Injection Site Pain on a Visual Analogue Scale (VAS)
Immediately after injection

The primary response variable is participant's immediate pain of injection on a visual analogue scale (VAS) of 0 to 10 (cm), with 0 representing no pain and 10 representing the worst possible pain.
