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 are 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. Negative mean changes from Baseline in the overall score indicate improvement in functional ability.
- Change From Baseline in C-reactive Protein Concentration Over Time [ Time Frame: Baseline and weeks 4, 8, 12, 16, 24, 36, and 48 ]C-reactive protein (CRP) is a specific measure of inflammatory activity.

The CDAI score ranges from 0-76 where lower scores indicate less disease activity.
- Change From Baseline in Simplified Disease Activity Index (SDAI) Over Time [ Time Frame: Baseline and weeks 4, 8, 12, 16, 24, 36, and 48 ]
The Simplified Disease Activity Index (SDAI) is a composite index that is calculated as the sum of the following items:

DAS28(CRP) scores range from 0 to approximately 10, with the upper bound dependent on the highest possible level of CRP. A DAS28 score higher than 5.1 indicates high disease activity, a DAS28 score less than 3.2 indicates low disease activity, and a DAS28 score less than 2.6 indicates clinical remission.

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 are 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. Negative mean changes from Baseline in the overall score indicate improvement in functional ability.
- Change From Baseline in Medical Outcomes Health Survey Short Form 36 Items Version 2 (SF-36 v2) at Week 24 [ Time Frame: Baseline and week 24 ]The SF-36 is a health-related survey that assesses participant's quality of life and consists of 36 questions covering 8 health domains. Two summary component scores are calculated: mental component summary score (MCS) and physical component summary score (PCS). The MCS consists of social functioning, vitality, mental health, and role-emotional scales and the PCS consists of physical functioning, bodily pain, role-physical, and general health scales. Each domain is scored by summing the individual items and transforming the scores into a 0 to 100 scale with higher scores indicating better health status or functioning.
- Change From Baseline in Modified Nail Psoriasis Severity Index (mNAPSI) at Week 24 [ Time Frame: Baseline and week 24 ]

- red spots in lunula (0 = absent, 1 = present)
- nail bed hyperkeratosis (0 = absent, 1 = present)
- splinter hemorrhages (0 = absent, 1 = present)
In participants with fingernails involved with psoriasis, each fingernail was scored at baseline to determine the worst fingernail (ie, the fingernail with the highest mNAPSI score). This fingernail was followed for the remainder of the study.
mNAPSI scores range from 0-13 where higher scores represent worse nail disease.

- Change From Baseline in Leeds Dactylitis Index (LDI) at Week 24 [ Time Frame: Baseline and week 24 ]The Leeds dactylitis index quantitatively measures dactylitis using the circumference of involved digits and control digits and tenderness of involved digits. Digits affected by dactylitis are defined as those with a 10% difference in the ratio of circumference of the affected digit to the contralateral digit. The control digit is either the contralateral digit (digit on opposite hand or foot), or if the contralateral digit is also affected, values from a standard reference table. Tenderness of affected digits is assessed on a scale from 0 [none] to 3 [worst]. The ratio of circumference between an affected digit and the control digit is multiplied by the tenderness score for the affected digit. The results from each involved digit are summed to provide the final LDI. A higher LDI indicates worse dactylitis.

- Change From Baseline in Spondyloarthritis Research Consortium of Canada (SPARCC) Enthesitis Index at Week 24 [ Time Frame: Baseline and week 24 ]The SPARCC enthesitis index assesses enthesitis at 18 sites for palpitation with a resultant total score of 0 to 16 (for scoring purposes, the inferior patella and tibial tuberosity are considered 1 site because of their anatomical proximity). Tenderness at each site is quantified on a dichotomous basis (0 = non-tender, 1 = tender). Entheses assessed are medial epicondyle (left and right), lateral epicondyle (left and right), supraspinatus insertion into greater tuberosity of humerus (left and right), greater trochanter (left and right), quadriceps insertion into superior border of patella (left and right), patellar ligament insertion into inferior pole of patella or tibial tubercle (left and right), Achilles tendon insertion into calcaneum (left and right), plantar fascia insertion into calcaneum (left and right). A higher count represents greater enthesitis burden.
