About

The purpose of this study is to compare the safety and efficacy of risankizumab versus placebo in participants with moderately to severely active psoriatic arthritis (PsA).

Full description

The study consists of a Screening Period (approximately 35 days), Period 1, Period 2, and a 20-week Follow-up Period. Period 1 is a 24-week randomized, double-blind, placebo-controlled, parallel-group treatment period. Period 2 is the long-term treatment period and starts at Week 24. To maintain the blind to the original treatment allocation, treatment at the Week 24 Visit is blinded: participants randomized to placebo receive blinded risankizumab 150 mg, and participants randomized to risankizumab receive blinded placebo. At Week 28 and for the remaining dosing visits (to Week 316), all participants are to receive open-label risankizumab 150 mg every 12 weeks. Participants will remain blinded to the original randomization allocation for the duration of the study. The total study duration is 336 weeks including a telephone call 140 days (20 weeks) after last dose of study drug.
