A Phase 4 interventional study of Risankizumab and Deucravacitinib in Moderate Plaque Psoriasis, sponsored by AbbVie. Completed at 88 sites in 12 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-04-15.

Psoriasis is a long-term skin disease which causes red, itchy, scaly patches most commonly on the knees, elbows, scalp, and torso (chest, back, and abdomen). In participants with psoriasis, certain skin cells multiply much faster and the skin can develop rough patches that may be red or white with scales. There are many types of psoriasis, but plaque psoriasis is the most common. The exact cause of psoriasis is unknown, but researchers think it may be caused by the body's immune system not working properly.
This study is designed to enroll 336 participants 18 years of age and older with have been diagnosed with moderate chronic plaque psoriasis for at least 6 months prior to Baseline (Day 1) and who have not previously been treated with a biologic treatment (natural substance that is made by using living cells in a laboratory). This is a Phase 4, randomized, open-label, assessor blinded, active comparator study with 2 Parts. Phase 4 studies test treatments that have already been approved to treat patients with a condition or disease. This study is open-label, which means that both participants and study doctors know which study treatment is given to participants
Participants will be administered subcutaneous (SC) treatment of risankizumab every 12 weeks for up to 44 weeks or provided deucravacitinib oral tablets to be taken once daily.
There may be higher treatment burden for participants in this trial compared to their standard of care (due to study procedures). Participants will attend regular (weekly, monthly) visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

Period A: Percentage of Participants Achieving 90% Improvement in Psoriasis Area Severity Index (PASI) Score (PASI 90)
The Psoriasis Area and Severity Index (PASI) is a composite score based on the degree of effect on body surface area of psoriasis and extension of erythema (reddening), induration (thickness), desquamation (scaling) of the lesions and area affected as observed on the day of examination. The severity of each sign was assessed using a 5-point scale, where 0=no symptoms, 1=slight, 2=moderate, 3=marked, 4=very marked. The PASI score ranges from 0 to 72, where 0 indicates no psoriasis and 72 indicates very severe psoriasis. PASI 90 is defined as at least a 90% reduction in PASI score compared with the Baseline PASI score. The percent reduction in score is calculated as (PASI score at Baseline - score at follow-up visit) / PASI score at Baseline \* 100.
Time frame: At Week 16
Period A: Percentage of Participants Achieving a Static Physician Global Assessment (sPGA) Score of 0 (Clear) or 1 (Almost Clear) with at least 2-grade improvement from Baseline
The static Physicians Global Assessment (sPGA) is an assessment by the investigator of the overall disease severity at the time of evaluation. Erythema (E), induration (I), and desquamation (D) are scored on a 5-point scale ranging from 0 (none) to 4 (severe). The sPGA composite score ranges from 0 to 4 and is calculated as Clear (0) = 0 for all three; Almost clear (1) = mean \>0, \<1.5; Mild (2) = mean ≥1.5, \<2.5; Moderate (3) = mean ≥2.5, \<3.5; and Severe (4) = mean ≥3.5.
Time frame: Baseline, Week 16
Period B: Percentage of Participants Achieving 90% Improvement in Psoriasis Area Severity Index (PASI) Score (PASI 90) in the Intent to Treat Population for non-responders in Period B (ITT_B_NR).
The Psoriasis Area and Severity Index (PASI) is a composite score based on the degree of effect on body surface area of psoriasis and extension of erythema (reddening), induration (thickness), desquamation (scaling) of the lesions and area affected as observed on the day of examination.

PASI 90 is defined as at least a 90% reduction in PASI score compared with the Baseline PASI score. The percent reduction in score is calculated as (PASI score at Baseline - score at follow-up visit) / PASI score at Baseline \* 100.
Time frame: At Week 52
Number of Participants Experiencing Adverse Events (AEs)
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not the event is considered causally related to the use of the product.
Time frame: Baseline up to 73 Weeks
