Title: (0554–0592) Spondyloarthritis Including Psoriatic Arthritis – Treatment Poster I
Session Type: Poster Session A
Session Time: 10:30AM-12:30PM
Background/Purpose: Psoriatic arthritis (PsA) affects up to one-third of patients with psoriasis;1 early identification and intervention for patients with psoriasis and risk factors (RFs) for progression to PsA, or those screening PsA-positive, may reduce progression.1
Methods: Data were pooled from the BE VIVID (NCT03370133), BE SURE (NCT03412747), and BE READY (NCT03410992) phase 3 trials, their open-label extension (OLE) BE BRIGHT (NCT03598790), and the BE RADIANT phase 3b trial (NCT03536884; including its OLE).2–6 Included patients received bimekizumab (BKZ) 320 mg every 4 weeks (Q4W) to Week 16, then Q4W or Q8W, and entered the OLE (BKZ Total). Data are also reported for the subset of patients who received BKZ Q4W to Week 16 then Q8W continuously (Q4W/Q8W). Achievement of 100% improvement from baseline in Psoriasis Area and Severity Index (PASI 100) was evaluated through Year 3 (OLE Week 96) in patients with baseline nail involvement (modified Nail Psoriasis Severity Index [mNAPSI] >10), and in patients screening PsA-positive at baseline (Psoriatic Arthritis Screening and Evaluation [PASE] ≥47). Patients with ≥3 RFs, including mNAPSI >10, scalp Investigator’s Global Assessment ≥3, PASI ≥20, and BMI >30 kg/m2, were also analyzed. 7–10 Modified non-responder imputation was used: patients discontinuing due to lack of efficacy or treatment-related adverse events were considered non-responders; multiple imputation was used for other missing data.
Results: Among 1,107 BKZ Total patients, 377, 189, and 320 had mNAPSI >10, PASE ≥47, or ≥3 RFs, respectively. Among Q4W/Q8W patients (Nf374), 129, 53, and 99 had mNAPSI >10, PASE ≥47, or ≥3 RFs, respectively. At Week 16, 61.8%, 68.8%, and 59.7% of BKZ Total patients with mNAPSI >10, PASE ≥47, or ≥3 RFs achieved PASI 100, respectively, consistent with the overall BKZ Total population (65.5%). At Year 3, 68.6%, 63.5%, and 66.9% achieved PASI 100, generally consistent with 70.2% overall.Responses were similar in Q4W/Q8W patients with mNAPSI >10/PASE ≥47/≥3 RFs at Week 16 (72.1%/69.8%/66.7%) and Year 3 (73.8%/66.3%/70.4%), consistent with Q4W/Q8W patients overall (Week 16/Year 3: 71.5%/74.0%).
Conclusion: Rates of complete skin clearance were high through Year 3 in BKZ-treated patients with psoriasis and PsA RFs at baseline, and those screening PsA-positive at baseline, consistent with the overall BKZ-treated group. These patients may benefit from highly effective psoriasis treatment, to help prevent progression in the long term.References: 1. Zabotti A. Ann Rheum Dis 2023;82:1162–70; 2. Reich K.
