Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Baseline in Disease Activity in Psoriatic Arthritis (DAPSA) Score at Month 1 | DAPSA assessed the joint domain of PsA and was derived from the sum of the following components: tender joint count (0-68), swollen joint count (0-66), C-reactive protein (CRP) level (milligram per deciliter [mg/dL]), participant assessment of pain (0 to 10 centimeter [cm] visual analog scale (VAS), 0= no pain, 10= worst possible pain), and participant's global assessment of disease activity on arthritis (0 to 10 cm VAS, 0= excellent and 10= poor). A higher DAPSA score indicated more active disease activity. The assessment did not have a score range with an upper or lower bound. The outcome measure compared response between anti-cyclic citrullinated peptide positive and negative participants. | Baseline, Month 1 | 
| Change From Baseline in Disease Activity in Psoriatic Arthritis (DAPSA) Score at Month 12 | DAPSA assessed the joint domain of PsA and was derived from the sum of the following components: tender joint count (0-68), swollen joint count (0-66), C-reactive protein (CRP) level (milligram per deciliter [mg/dL]), participant assessment of pain (0 to 10 centimeter [cm] visual analog scale (VAS), 0= no pain, 10= worst possible pain), and participant's global assessment of disease activity on arthritis (0 to 10 cm VAS, 0= excellent and 10= poor). A higher DAPSA score indicated more active disease activity. The assessment did not have a score range with an upper or lower bound. The outcome measure compared response between anti-cyclic citrullinated peptide positive and negative participants. | Baseline, Month 12 |
