A Study to Assess Targeted Therapies for Treatment of Adults With Moderate to Severe Psoriasis

November 6, 2026 updated by: AbbVie

A Phase 2 Multicenter Platform Trial of Targeted Therapies for Treatment of Adult Subjects With Moderate to Severe Psoriasis

Psoriasis is a long-term skin disease that causes inflammation, thick skin, and scaly patches on the skin. This study evaluates the safety and effectiveness of risankizumab in combination with ABBV-295 compared with risankizumab alone in adult participants with moderate to severe psoriasis.

Risankizumab is an approved drug for the treatment of moderate to severe psoriasis. Participants are placed in 1 of 2 groups, called treatment arms. Each group receives a different treatment. Participants will receive either risankizumab plus ABBV-295 or risankizumab plus ABBV-295 matching placebo. Around 105 adult participants with moderate to severe psoriasis will be enrolled in the study at approximately 50 sites worldwide.

Participants will receive injections of risankizumab and ABBV-295 or risankizumab and ABBV-295 matching placebo for up to 52 weeks, with a 20-week follow-up period after the last dose of the study.

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 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.

Description

Inclusion Criteria:

  • Clinical diagnosis of chronic plaque psoriasis (PsO) with or without psoriatic arthritis for at least 6 months before the Baseline Visit
  • Stable moderate to severe chronic plaque psoriasis with or without Psoriatic arthritis (PsA) at both Screening and Baseline Visit defined as follows: ≥ 10% Body Surface Area psoriasis involvement, Static Physician's Global Assessment score of ≥ 3, and PASI score ≥ 12
  • Candidates for systemic therapy or phototherapy as assessed by the investigator.

Exclusion Criteria:

  • Participants with any form of PsO other than chronic plaque PsO (e.g., pustular PsO, palmoplantar pustulosis, acrodermatitis of Hallopeau, erythrodermic, or guttate PsO).
  • Participants with a history of current drug-induced PsO or a drug-induced exacerbation of pre-existing PsO.
  • Participants with a history of active ongoing inflammatory skin diseases other than PsO (with or without PsA) that could interfere with the assessment of PsO (e.g., hyperkeratotic eczema).

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants Achieving at least a 90% reduction from Baseline in Psoriasis Area and Severity Index (PASI 90)
Time Frame: Week 28

PASI is a measure of psoriatic disease severity taking into account the overall severity of erythema, induration and scaling, and the extent of affected area in each of four anatomical regions (head, trunk, upper extremities, and lower extremities). PASI scores range from 0 (no psoriasis) to 72 (severe disease over the entire body surface). Higher scores indicate worse disease severity. PASI 90 indicates at least 90% improvement from baseline.

Week 28
Number of Participants with Adverse Events (AEs)
Time Frame: Up to 72 Weeks

An AE is defined as any untoward medical occurrence in a patient or clinical investigation in which a participant is administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment.

Up to 72 Weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants Achieving 100% Reduction from Baseline in PASI 100
Time Frame: Week 28

PASI is a measure of psoriatic disease severity taking into account the overall severity of erythema, induration and scaling, and the extent of affected area in each of four anatomical regions (head, trunk, upper extremities, and lower extremities). PASI scores range from 0 (no psoriasis) to 72 (severe disease over the entire body surface). Higher scores indicate worse disease severity. PASI 100 indicates at least 100% improvement from baseline.

Week 28
Percentage of Participants Achieving ≥10% Body Weight Reduction from Baseline
Time Frame: Week 28

Achievement of at least 10% body weight reduction from Baseline.

Week 28
Percent Change from Baseline in Body Weight
Time Frame: Week 28

Percent change from Baseline in body weight.
