- Proportion of Participants Simultaneously Achieving American College of Rheumatology (ACR)50 and Psoriasis Area and Severity Index (PASI)100 [ Time Frame: Week 24 ]Proportion of participants simultaneously achieving ACR50 and PASI100 will be derived from the number of participants who have achieved PASI100 and achieved ACR50 divided by the total number of participants.
- Proportion of Participants Achieving ACR50 [ Time Frame: Week 24 ]ACR50 response is defined as a ≥50% improvement from baseline for tender joint count (TJC) and swollen joint count (SJC) and in at least 3 of the following 5 criteria: Participant's assessment of joint pain Visual Analog Scale (VAS), Participant's Global Assessment of Disease Activity (PatGA) VAS, Physician's Global Assessment of Disease Activity (PGA) VAS, participant's assessment of physical function using the Health Assessment Questionnaire-Disability Index (HAQ-DI), or High Sensitivity (assay) C-Reactive Protein (hs-CRP).
- Proportion of Participants Achieving PASI100 [ Time Frame: Week 24 ]The PASI is an index that combines assessments of the extent of body-surface involvement in 4 anatomical regions (head, trunk, arms, and legs) and the severity of desquamation, erythema, and plaque induration/infiltration (thickness) in each region, yielding an overall score of 0 for no psoriasis to 72 for the most severe disease. Participants achieving PASI 100 are defined as having an improvement of 100% in the PASI score compared to baseline.
- Change from Baseline in TJC [ Time Frame: Baseline, Week 52 ]TJC is determined by examination of 68 joint counts that are assessed for tenderness by pressure and joint manipulation on physical examination.
- Change from Baseline in SJC [ Time Frame: Baseline, Week 52 ]SJC is determined by examination of 66 joint counts that are classified as either swollen or not swollen. Swelling is defined as palpable fluctuating synovitis of the joint.
- Change from Baseline in Participant's Assessment of Pain VAS [ Time Frame: Baseline, Week 52 ]Participants are asked to assess his/her current level of arthritis pain by marking a vertical tick on a horizontal VAS with the left end marked as "no pain" and the right end marked "worst possible pain."
- Change from Baseline in Participant's Global Assessment of Disease Activity [ Time Frame: Baseline, Week 52 ]The participant's overall assessment of his or her PsA activity are recorded using a horizontal VAS.
- Change from Baseline in Physician's Global Assessment of Disease Activity [ Time Frame: Baseline, Week 52 ]The investigator, who must be a physician, is asked to give an overall assessment of the severity of the participant's current PsA activity using a horizontal VAS.
- Change from Baseline in C-Reactive Protein (CRP) [ Time Frame: Baseline, Week 52 ]CRP is the ACR Core Set laboratory measure of acute-phase reactant.
- Change from Baseline in HAQ-DI [ Time Frame: Baseline, Week 52 ]HAQ-DI is a participant reported questionnaire that measures disease-associated disability (physical function). It consists of 24 questions with 8 domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and other daily activities. The disability section scores the participant's self-perception on the degree of difficulty (0 = without any difficulty, 1 = with some difficulty, 2 = with much difficulty, and 3 = unable to do), covering the 8 domains. The reported use of special aids or devices and/or the need for assistance of another person to perform these activities is assessed. The HAQ-DI is a composite ranging from 0-3 with lower scores indicating less functional disability.
- Proportion of Participants Simultaneously Achieving ACR50 and PASI100 [ Time Frame: Week 52 ]Proportion of participants simultaneously achieving ACR50 and PASI100 will be derived from the number of participants who have achieved PASI100 and achieved ACR50 divided by the total number of participants.
- Change from Baseline in Disease Activity Score-CRP (DAS28-CRP) [ Time Frame: Baseline, Week 52 ]The DAS28-CRP is a measure of disease activity in 28 joints that consists of a composite numerical score with the following variables: TJC28, SJC28, hs-CRP (measured in milligrams per liter), and Participant's Global Assessment of Disease Activity recorded by participants on a 0 to 100 VAS. For DAS28-CRP, the Tender Joint Count 28 (TJC28) and Swollen Joint Count (SJC28) are a subset of TJC and SJC, and include 14 joints on each side of the body: 2 shoulders, 2 elbows, 2 wrists, 10 metacarpophalangeal joints, the 2 interphalangeal joints of the thumb, the 8 proximal interphalangeal joints, and the 2 knees.
- Proportion of Participants Achieving Minimal Disease Activity (MDA) [ Time Frame: Week 52 ]MDA is achieved if 5 of 7 outcome measures are fulfilled: TJC ≤1; SJC ≤1; psoriasis activity and severity index (PASI total score) ≤1 or BSA ≤3; participant pain VAS score of ≤15; participant global disease activity VAS score of ≤20; HAQ-DI score ≤0.5; and tender entheseal points ≤1.
- Proportion of Participants Achieving Psoriatic Arthritis Response Criteria (PsARC) [ Time Frame: Week 52 ]The PsARC is a composite criteria reported in terms of the percentage of participants achieving response according to the following criterion: TJC, SJC, PGA, and PatGA. Overall response is defined by improvement from baseline assessment in 2 of 4 criteria, 1 of which must be a joint count; there must not be worsening in any of the 4 criteria: at least 30% reduction in TJC, at least 30% reduction in SJC, at least a 20 millimeter (mm) reduction in PGA and at least a 20 mm reduction in PatGA.
- Change from Baseline in Modified Composite Psoriatic Disease Activity Index (CPDAI) Score (Modified) [ Time Frame: Baseline, Week 52 ]The CPDAI is a validated instrument intended to assess composite psoriatic disease activity and response to therapy. Domains include peripheral arthritis as assessed by the number of tender and swollen joints and the HAQ-DI, skin as assessed by the PASI and the Dermatology Life Quality Index (DLQI), enthesitis as assessed by the number of sites with enthesitis and the HAQ-DI, and dactylitis as assessed by the number of digits affected and the HAQ-DI.
- Change from Baseline in the Spondyloarthritis Research Consortium of Canada (SPARCC) Enthesitis Index in Participants with Enthesitis at Baseline [ Time Frame: Baseline, Week 52 ]The SPARCC enthesitis index evaluates tenderness in a total of 16 enthesitis sites: the greater trochanter (right/left [R/L]), quadriceps tendon insertion into the patella (R/L), patellar ligament insertion into the patella and tibial tuberosity (R/L), Achilles tendon insertion (R/L), plantar fascia insertion (R/L), medial and lateral epicondyles (R/L), and the supraspinatus insertion (R/L).
- Change from Baseline in the Leeds Enthesitis Index (LEI) in Participants with Enthesitis at Baseline [ Time Frame: Baseline, Week 52 ]The LEI was developed specifically for use in PsA. It measures enthesitis at 6 sites (lateral epicondyle, left and right; medial femoral condyle, left and right; Achilles tendon insertion, left and right).
- Change from Baseline in the Leeds Dactylitis Index-Basic (LDI-B) in Participants with Dactylitis at Baseline [ Time Frame: Baseline, Week 52 ]The LDI-B measures the severity of dactylitis. In each digit, the ratio of the circumference of the affected digit to the circumference of the digit on the opposite hand or foot measured in mm. Each dactylitic digit is defined by a minimum increase of 10% in circumference over the contra-lateral digit.
- Change from Baseline in Psoriasis Body Surface Area (BSA) [ Time Frame: Baseline, Week 52 ]The investigator evaluates the percentage involvement of psoriasis on each participant's BSA on a continuous scale from 0% = no involvement to 100% = full involvement, where 1% corresponded to the size of the participant's handprint including the palm, fingers, and thumb.
- Change from Baseline in the Nail Psoriasis Severity Index (NAPSI) Fingernails Score in the Subgroup of Participants with Fingernail Involvement at Baseline [ Time Frame: Baseline, Week 52 ]The NAPSI scale is used to evaluate the severity of fingernail bed Ps and fingernail matrix Ps by area of involvement. The fingernail is divided into quadrants. Each fingernail is given a score for fingernail bed Ps 0 (none) to 4 (Ps in 4 quadrants of the fingernail) and fingernail matrix Ps 0 (none) to 4 (Ps in 4 quadrants of the matrix), depending on the presence (score of 1) or absence (score of 0) of any of the features of fingernail bed or matrix Ps in each quadrant. The sum of all fingernails equals the total NAPSI score range is from 0 (no effect) to 80 (more severe psoriasis).
- Change from Baseline in the Itch NRS [ Time Frame: Baseline, Week 52 ]The Itch NRS is a participant-administered, 11-point horizontal scale anchored at 0 and 10, with 0 representing "no itch" and 10 representing "worst itch imaginable." Overall severity of a participant's itching from psoriasis is indicated by circling the number that best described the worst level of itching in the past 24 hours.
- Change from Baseline in Fatigue Severity NRS (Fatigue NRS) Score [ Time Frame: Baseline, Week 52 ]The Fatigue Severity NRS is a participant-administered single-item 11-point horizontal scale anchored at 0 and 10, with 0 representing "no fatigue" and 10 representing "as bad as you can imagine." Participants rate their fatigue (weariness, tiredness) by circling the 1 number that described their worst level of fatigue during the past 24 hours.
- Change From Baseline in Medical Outcomes Study 36-item Short Form Health Survey (SF-36): Physical Component Summary (PCS) [ Time Frame: Baseline, Week 52 ]SF-36 is a standardized participant-administered measure designed to evaluate 8 domains of functional health and well-being.
