NRI was used for missing data.
Tender Joint Count (TJC68): Change From Baseline to Week 16Baseline, Week 16Sixty-eight joints were assessed and classified as either tender (1) or not tender (0). A negative change represents a decrease in the number of tender joints.
Swollen Joint Count (SJC): Change From Baseline to Week 16Baseline, Week 16Sixty-six joints were assessed and classified as either swollen (1) or not swollen (0). A negative change represents a decrease in the number of tender joints.
Health Assessment Questionnaire Disability Index (HAQ-DI) Score: Change From Baseline to Week 16Baseline, Week 16The HAQ-DI is a patient-reported questionnaire specific for rheumatoid arthritis that consists of 20 questions referring to 8 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 0 represents no disability and 3 very severe, high-dependency disability. HAQ remission indicating normal physical function is defined by HAQ-DI score of \< 0.5. A negative change from Baseline indicates improvement.
Short Form-36 Health Status Survey (SF-36) Physical Component: Change From Baseline to Week 16Baseline, Week 16The SF-36 determined participant's overall quality of life by assessing 1) limitations in physical functioning due to health problems; 2) limitations in usual role because of physical health problems; 3) bodily pain; 4) general health perceptions; 5) vitality; 6) limitations in social functioning because of physical or emotional problems; 7) limitations in usual role due to emotional problems; and 8) general mental health. Items 1-4 comprise the physical component of the SF-36. Scores on each item were summed and averaged (range = 0-100); a positive change from Baseline indicates improvement.
Percentage of Participants Achieving American College of Rheumatology 50% (ACR50) Response at Week 16Week 16Response defined by ACR50 criteria (improvement from baseline) at Week 16: ≥ 50% improvement in tender joint count; ≥ 50% improvement in swollen joint count; and ≥ 50% improvement in at least 3 of the 5 following parameters: * Patient assessment of pain * Patient global assessment of disease activity * Investigator's global assessment of disease activity * HAQ-DI * Acute phase reactant value (C-reactive protein). NRI was used for missing data.
Dactylitis Count: Change From Baseline to Week 16 in Participants With Dactylitis at BaselineBaseline, Week 16The number of fingers and toes with dactylitis (ranging from 0 to 20). A negative change represents a decrease in the number of fingers and toes affected by dactylitis.
Spondyloarthritis Research Consortium of Canada (SPARCC) Enthesitis Index: Change From Baseline to Week 16 in Participants With Enthesitis at BaselineBaseline, Week 16Assessment of enthesitis was performed in the following 16 domains: left and right (L/R) medial epicondyle; L/R lateral epicondyle; L/R supraspinatus insertion into the greater tuberosity of humerus; L/R greater trochanter; L/R quadriceps insertion into superior border of patella; L/R patellar ligament insertion into inferior pole of patella or tibial tubercle; L/R Achilles tendon insertion into calcaneum; L/R plantar fascia insertion into calcaneum. Tenderness at each site was classified as either absent (0) or present (1) to yield total SPARCC scores ranging from 0 (0 sites with tenderness) to 16 (16 sites with tenderness). A negative change from Baseline indicates improvement.
Modified Nail Psoriasis Severity Index (mNAPSI): Change From Baseline to Week 16Baseline, Week 16mNAPSI grades each fingernail for onycholysis (separation of the nail plate from the nail bed) and oil-drop (salmon patch) dyschromia (reddish-brown discoloration under the nail plate) on a scale of 0 (none present) to 3 (\>30% of the nail); pitting (small, sharply defined depressions in the nail surface) on a scale of 0 (0 pits present) to 3 (\>50 pits present); nail plate crumbling on a scale of 0 (no crumbling) to 3 (\>50% of nail has crumbling); and presence (1) or absence (0) of leukonychia (white spots), splinter hemorrhages, nail bed hyperkeratosis, and red spots in the lunula. mNAPSI is calculated as the sum of all the components for all of the participants fingernails, for a minimal - maximal total score of 0 to 130. A negative change from Baseline indicates improvement.
Percentage of Participants Achieving 90% Improvement in Psoriasis Area and Severity Index (PASI) Score (PASI90) at Week 16Week 16PASI is a composite score based on the degree of effect on body surface area of psoriasis and the extension of erythema (reddening), induration (thickness), desquamation (scaling) of the lesions and area affected as observed on the day of examination. The severity of each sign was assessed using a 5-point scale, where 0=no symptoms, 1=slight, 2=moderate, 3=marked, 4=very marked. The PASI score ranges from 0 to 72, where 0 indicates no psoriasis and 72 indicates very severe psoriasis. PASI90 is defined as at least a 90% reduction in PASI score compared with the Baseline PASI score. The percent reduction in score is calculated as (PASI score at Baseline - score at follow-up visit) / PASI score at Baseline \* 100. The percentage of participants achieving PASI90 at Week 16 are provided. NRI was used for missing data.
SF-36 Mental Component: Change From Baseline to Week 16Baseline, Week 16The SF-36 determined participant's overall quality of life by assessing 1) limitations in physical functioning due to health problems; 2) limitations in usual role because of physical health problems; 3) bodily pain; 4) general health perceptions; 5) vitality; 6) limitations in social functioning because of physical or emotional problems; 7) limitations in usual role due to emotional problems; and 8) general mental health. Items 5-8 comprise the mental component of the SF-36. Scores on each item were summed and averaged (range = 0-100); a positive change from Baseline indicates improvement.

Percentage of Participants Achieving 90% Improvement in Psoriasis Area and Severity Index (PASI) Score (PASI90) at Week 16

PASI is a composite score based on the degree of effect on body surface area of psoriasis and the extension of erythema (reddening), induration (thickness), desquamation (scaling) of the lesions and area affected as observed on the day of examination. The severity of each sign was assessed using a 5-point scale, where 0=no symptoms, 1=slight, 2=moderate, 3=marked, 4=very marked. The PASI score ranges from 0 to 72, where 0 indicates no psoriasis and 72 indicates very severe psoriasis. PASI90 is defined as at least a 90% reduction in PASI score compared with the Baseline PASI score. The percent reduction in score is calculated as (PASI score at Baseline - score at follow-up visit) / PASI score at Baseline \* 100. The percentage of participants achieving PASI90 at Week 16 are provided. NRI was used for missing data.

SF-36 Mental Component: Change From Baseline to Week 16

The SF-36 determined participant's overall quality of life by assessing 1) limitations in physical functioning due to health problems; 2) limitations in usual role because of physical health problems; 3) bodily pain; 4) general health perceptions; 5) vitality; 6) limitations in social functioning because of physical or emotional problems; 7) limitations in usual role due to emotional problems; and 8) general mental health. Items 5-8 comprise the mental component of the SF-36. Scores on each item were summed and averaged (range = 0-100); a positive change from Baseline indicates improvement.

Spondyloarthritis Research Consortium of Canada (SPARCC) Enthesitis Index: Change From Baseline to Week 16 in Participants With Enthesitis at Baseline

Assessment of enthesitis was performed in the following 16 domains: left and right (L/R) medial epicondyle; L/R lateral epicondyle; L/R supraspinatus insertion into the greater tuberosity of humerus; L/R greater trochanter; L/R quadriceps insertion into superior border of patella; L/R patellar ligament insertion into inferior pole of patella or tibial tubercle; L/R Achilles tendon insertion into calcaneum; L/R plantar fascia insertion into calcaneum. Tenderness at each site was classified as either absent (0) or present (1) to yield total SPARCC scores ranging from 0 (0 sites with tenderness) to 16 (16 sites with tenderness). A negative change from Baseline indicates improvement.
