About

The purpose of this study is to evaluate safety and efficacy of risankizumab in participants with ulcerative colitis (UC) in participants who responded to induction treatment with risankizumab in a prior AbbVie study of risankizumab in UC. This study consists of three sub-studies and a Continuous Treatment Extension (CTE): Substudy 1 is a 52-week, randomized, double-blind, placebo-controlled maintenance study; Substudy 2 is 52-week, randomized, exploratory maintenance study; and Substudy 3 is an open-label long-term extension study for participants who completed Substudy 1 or 2, or participants who responded to induction treatment in Study M16-067 with no final endoscopy due to the Covid-19 pandemic or due to the geopolitical conflict in Ukraine and surrounding impacted regions. The CTE is an open-label extension for Substudy 3 completers to ensure continuous treatment with risankizumab until such time that risankizumab becomes commercially available and/or the subject can access treatment locally or can transition to a Continued Treatment for Trial Participants Open-Label Extension study.

1,242 participants in 8 patient groups, including a placebo group

Substudy 1: Double-blind Placebo
Placebo Comparator group
Description:
Participants randomized to receive placebo for risankizumab administered by subcutaneous (SC) injection.
Treatment:
Drug: placebo for risankizumab
Substudy 1: Double-blind Risankizumab Dose 1
Experimental group
Description:
Participants randomized to receive risankizumab dose 1 administered by subcutaneous (SC) injection.
Treatment:
Drug: risankizumab
Substudy 1: Double-blind Risankizumab Dose 2
Experimental group
Description:
Participants randomized to receive risankizumab dose 2 administered by subcutaneous (SC) injection.
Treatment:
Drug: risankizumab
Substudy 2: Open-label (OL) Clinical Assessment Risankizumab
Experimental group
Description:
Participants randomized to receive risankizumab dose 1 administered by subcutaneous (SC) injection.
Treatment:
Drug: risankizumab
Substudy 2: OL Therapeutic Drug Monitoring Risankizumab
Experimental group
Description:
Participants randomized to receive risankizumab dose 1 administered by subcutaneous (SC) injection.
Treatment:
Drug: risankizumab
Substudy 3: OL Extension Risankizumab
Experimental group
Description:
Participants who completed Sub-study 1 or 2 receive open-label risankizumab in Sub-study 3.
Treatment:
Drug: risankizumab
OL Continuous Treatment Extension - Dose 1
Experimental group
Description:
Participants who complete Sub-study 3 and continue to tolerate and derive benefit from receiving risankizumab, will continue to receive risankizumab based on their assignment during Sub-study 3. Participants completing Sub-study 3 without receiving risankizumab rescue therapy in any sub-study will receive risankizumab Dose 1 administered by subcutaneous (SC) injection.
Treatment:
Drug: risankizumab
OL Continuous Treatment Extension - Dose 2
Experimental group
Description:
Participants who complete Sub-study 3 and continue to tolerate and derive benefit from receiving risankizumab, will continue to receive risankizumab based on their assignment during Sub-study 3. Participants completing Sub-study 3 and received risankizumab rescue therapy in any sub-study will receive risankizumab Dose 2 administered by subcutaneous (SC) injection.
Treatment:
Drug: risankizumab
