Brief summary

Proportion of participants achieving ACR50 (ie, ≥50% improvement on the ACR response criteria) at Week 16

Detailed description

1. Proportion of participants achieving ACR20 (ie, ≥20% improvement on the ACR response criteria) at Week 16, 2. Proportion of participants achieving Minimal Disease Activity (MDA) at Week 16, 3. Change from Baseline in Health Assessment Questionnaire—Disability Index (HAQ-DI) at Week 16, 4. Proportion of participants achieving a decrease of ≥90% in the Psoriasis Area and Severity Index (PASI90) response at Week 16 in the subgroup of participants with PsO involving ≥3% body surface area at Baseline, 5. Change from Baseline in SF-36 PCS at Week 16, 6. Change from Baseline to Week 16 in joint/bone structural damage (van der Heijde modified Total Sharp Score), 7. Incidence, relatedness, severity, and seriousness of TEAEs, 8. Withdrawal due to TEAEs, 9. Clinically relevant abnormalities in vital signs (blood pressure and heart rate) and body weight, 10.
