OBJECTIVE: To evaluate the effect of brodalumab on psoriasis signs and symptoms assessed by the Psoriasis Symptom Inventory (PSI) in patients with psoriatic arthritis (PsA).
METHODS: This prespecified analysis of a phase II study (NCT01516957) evaluated patients with active PsA and psoriasis-affected body surface area ≥ 3%, randomized to brodalumab (140 or 280 mg) or placebo every 2 weeks (Q2W) for 12 weeks with loading dose at Week 1. At Week 12, patients entering an open-label extension received brodalumab 280 mg Q2W. The PSI measures 8 psoriasis signs and symptoms: itch, redness, scaling, burning, stinging, cracking, flaking, and pain. PSI response is defined as total PSI ≤ 8 (range 0-32), each item ≤ 1 (range 0-4). PSI scores were assessed at weeks 12 and 24.
RESULTS: There were 107 eligible patients. At Week 12, mean improvement in PSI scores was 7.8, 11.2, and 1.5 in brodalumab 140 mg, 280 mg, and placebo groups, respectively; by Week 24, improvement was 10.2, 12.4, and 11.7. At Week 12, 75.0%, 81.8%, and 16.7% of patients receiving brodalumab 140 mg, 280 mg, and placebo, respectively, achieved PSI response; improvement was sustained through Week 24, when 83.9% of prior placebo recipients achieved response. At Week 12, 25.0%, 36.4%, and 2.8% of patients receiving brodalumab 140 mg, 280 mg, and placebo, respectively, achieved PSI 0. Percentages improved through Week 24: 40.0% brodalumab 140 mg, 42.9% brodalumab 280 mg, and 48.4% placebo.
CONCLUSION: Significantly more brodalumab-treated patients with PsA achieved patient-reported improvements in psoriasis signs and symptoms than did those receiving placebo. Improvements were comparable between brodalumab groups.
