Individuals aged 6 to less than 18 years old with a diagnosis of chronic plaque psoriasis for at least 6 months, may qualify to participate.
The study consists of 4 parts, each with distinct populations:
As the study progresses, some parts may no longer be enrolling.
Parts 1, 3, and 4 are open-label and all participants will receive investigational medication (active study drug), via injection. In Part 2, participants will receive one of two active study drugs during Period A; medication assignment may then change for Period B. Study medication and study-related procedures will be provided at no cost. Reimbursement for study-related expenses will also be provided.
Study participation in Parts 1, 3, and 4 will be about 65 weeks and involve about 9 visits to the study centre, plus a follow-up phone call.
In Part 2, study duration may be longer (81 weeks) and involve additional visits to the study centre.

Psoriasis is a chronic, systemic, inflammatory disease in which skin cells build up and develop thick, red and white scaly patches on the skin. There is an unmet medical need for effective treatment in pediatric patients and this study is being done to evaluate risankizumab in pediatric participants with moderate to severe plaque psoriasis. This study will assess the change in disease symptoms. Risankizumab is a drug being studied for the treatment for plaque psoriasis in pediatric participants. This study has 4 parts. Part 1: Participants aged 12 < 18 will receive a fixed dose of risankizumab. Part 2: Participants aged 12 < 18 will receive; Period A: Risankizumab or ustekinumab based on body weight followed by; Period B: Risankizumab or no treatment. Period C: Re-treatment with risankizumab (if needed). Part 3: Participants aged 6 < 12 will receive risankizumab based on body weight. Part 4: Participants aged 6 < 12 will receive risankizumab based on body weight (Japan only: Participants aged 12 > 18 will receive risankizumab based on body weight). Around 132 participants will be enrolled in approximately 50 sites worldwide. Risankizumab and ustekinumab are given as a subcutaneous (under the skin) injection. Parts 1, 3, and 4: Risankizumab for 40 weeks with a follow-up call 20 weeks later for a study duration of approximately 65 weeks. Part 2: Period A: Risankizumab or ustekinumab for 16 weeks. Period B: Risankizumab or no treatment for 36 weeks. Period C: Re-treatment with risankizumab for 16 weeks. Follow-up call 20 weeks later for a study duration of approximately 81 weeks. Participants from each Part who meet eligibility criteria for an open-label extension (OLE) study may continue on risankizumab for 216 additional weeks. There may be a higher burden for study participants compared to standard treatment. Participants will attend monthly visits and medical assessments will check the effect of treatment through blood tests, questionnaires, and checking for side effects.
Condition or Disease:
Ages Eligible for Study:
6 Years and 17 Years (Child)
Sexes Eligible for Study:
Diagnosis of chronic plaque psoriasis for at least 6 months before the Baseline Visit.
Stable severe or moderate to severe plaque psoriasis as defined in each study part by body surface area (BSA) psoriasis involvement and scores on the Psoriasis Area and Severity Index (PASI) and Static Physician Global Assessment (sPGA).
Candidate for systemic therapy as assessed by the investigator and meet the disease activity criteria at both the Screening and Baseline Visits per the protocol.
– Concurrent clinically significant medical conditions other than the indication being studied or any other reason that the investigator determines would interfere with the participant’s participation in this study, would make the participant an unsuitable candidate to receive study drug, or would put the participant at risk by participating in the study.
