Real-World Skin Clearance and Quality of Life with risankizumab in Patients with Psoriasis with Moderate Skin Involvement and Those Eligible for Systemic Therapy Per International Psoriasis Council Classification.

introductionThe International Psoriasis Council (IPC) reclassified patients eligible for systemic therapy to include those with body surface area (BSA) > 10%, psoriasis lesions in high-impact areas, or failure of topical therapy. Risankizumab is an interleukin-23 inhibitor approved for the treatment of moderate-to-severe plaque psoriasis. This retrospective study evaluated the real-world effectiveness of risankizumab in patients with BSA 3-10% and patients meeting IPC systemic therapy criteria, addressing existing gaps in knowledge regarding its effectiveness in these patient groups.

methodsBiologic-naïve adults with moderate-to-severe plaque psoriasis who initiated risankizumab between April 2019 and August 2023 and were treated for 12 (± 3) months were identified from the CorEvitas Psoriasis Registry and stratified by baseline BSA. At 12 months, skin clearance was assessed by achievement of Psoriasis Area Severity Index (PASI) 90, PASI 100, and National Psoriasis Foundation (NPF) treat-to-target goals. Patient-reported outcomes (PROs) included achievement of Dermatology Life Quality Index (DLQI) 0/1, improvements in psoriasis symptoms, and work and activity impairment.

resultsOf 272 patients analyzed, 123 had BSA 3-10% (78 had any high-impact area involvement and 105 had prior topical therapy experience) and 149 patients had BSA > 10%. Among those with BSA 3-10%, 77.9% achieved PASI 90 and 67.2% achieved PASI 100. NPF acceptable and target responses were met by 95.3% and 87.9%, respectively. Regarding PROs, 68.1% of patients with moderate skin involvement (BSA 3-10%) attained a DLQI score of 0/1. Significant improvements from baseline in psoriasis symptoms and reductions in work and life impairments were also reported (P < .001). Comparable positive outcomes were observed across all IPC systemic therapy eligible patient subgroups.

conclusionIn patients with BSA 3-10% and those systemic-eligible per IPC classification, continuous treatment with risankizumab for 12 months resulted in high levels of skin clearance and improvements in PROs.
