About this study
Official title: A Randomized, Active-Controlled, Efficacy Assessor-Blinded Study to Evaluate Pharmacokinetics, Safety and Efficacy of Risankizumab in Patients From 6 to Less Than 18 Years of Age With Moderate to Severe Plaque Psoriasis
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.

Change From Baseline in Children's Dermatology Life Quality Index (CDLQI) Total Score
The CDLQI is a 10-item, validated questionnaire used in clinical practice and clinical trials to assess the impact of dermatologic disease symptoms and treatment on quality of life (QOL). The CDLQI items include symptoms and feelings, daily activities, leisure, school, relationships, sleep, and treatment. Each item was scored on a 4-point scale: 0 = not at all; 1 = only a little; 2 = quite a lot; and 3 = very much. Item scores (0 to 3) were added to provide a total score range of 0 to 30 with higher scores representing greater impairment of QOL and worse outcomes. A negative change from baseline score indicated a reduced impairment of QOL.

- 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.

Primary outcome
Percentage of Participants Achieving Psoriasis Area Severity Index (PASI) 75 (Defined as at Least 75% Improvement in PASI)
Time frame: Baseline (Week 0) to Week 16 of initial treatment in each part of the study (Parts 1-4)
The PASI is used to evaluate a participant's overall psoriasis disease state that includes the percent of surface area of skin that is affected and the severity of erythema, induration, and desquamation over four body regions (head, upper extremities, trunk, and lower extremities). Scores range from 0 to 72, with the highest score representing the worst outcome (complete erythroderma of the severest degree). Data are reported for the percentage of participants achieving at least a 75% improvement in PASI.
Percentage of Participants Achieving Static Physician's Global Assessment (sPGA) of Clear or Almost Clear (Score of 0 or 1)
Time frame: At Week 16 of initial treatment in each part of the study (Parts 1-4)
The sPGA is the physician's current assessment of the average thickness, erythema, and scaling of all psoriatic lesions. Scores range from 0 (clear) to 4 (severe) with higher scores representing worse outcomes. Data are reported for the percentage of participants achieving sPGA of clear (score of 0) or almost clear (score of 1).
Percentage of Participants Achieving Static Physician's Global Assessment (sPGA) of Clear or Almost Clear (Score of 0 or 1) and With at Least 2 Grade Improvement From Baseline
Time frame: Baseline (Week 0) to Week 16 of initial treatment in each part of the study (Parts 1-4)
The sPGA is the physician's current assessment of the average thickness, erythema, and scaling of all psoriatic lesions. Scores range from 0 (clear) to 4 (severe) with higher scores representing worse outcomes. Data are reported for the percentage of participants achieving sPGA of clear (score of 0) or almost clear (score of 1).

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Risankizumab and Ustekinumab in people with Psoriasis, run by AbbVie at 53 sites in 7 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 20 May 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 53 sites in United States, Germany, Japan, United Kingdom, Poland and 2 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 20 May 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of Participants Achieving Psoriasis Area Severity Index (PASI) 75 (Defined as at Least 75% Improvement in PASI) (time frame: Baseline (Week 0) to Week 16 of initial treatment in each part of the study (Parts 1-4)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 May 2025.
