A Phase 3, Randomized, Double-Blind, Study Comparing Risankizumab to Placebo in Subjects With Active Psoriatic Arthritis (PsA) Who Have a History of Inadequate Response to or Intolerance to at Least One Disease Modifying Anti-Rheumatic Drug (DMARD) Therapy (KEEPsAKE 1)

Overview
Brief Summary
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).
Detailed 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.

Arms & Interventions
Placebo
Participants randomized to receive double-blind placebo at Week 0, Week 4, and Week 16 in Period 1. At Week 24 participants will receive 150 mg risankizumab followed by open-label 150 mg risankizumab at Week 28, and every 12 weeks thereafter in Period 2 until the final dosing time point at Week 316.
Intervention: Placebo
Placebo
Participants randomized to receive double-blind placebo at Week 0, Week 4, and Week 16 in Period 1. At Week 24 participants will receive 150 mg risankizumab followed by open-label 150 mg risankizumab at Week 28, and every 12 weeks thereafter in Period 2 until the final dosing time point at Week 316.
Intervention: Risankizumab
Risankizumab
Participants randomized to receive 150 mg risankizumab administered by subcutaneous injection at Week 0, Week 4, and Week 16 in Period 1. At Week 24 participants will receive blinded placebo followed by open-label 150 mg risankizumab at Week 28, and every 12 weeks thereafter in Period 2 until the final dosing time point at Week 316.
Intervention: Placebo
