Key clinical point: Guselkumab administered every 4 weeks (Q4W) or every 8 weeks (Q8W) yielded better clinical outcomes than placebo in patients with psoriatic arthritis (PsA), without any new safety concerns.
Major findings: At week 24, a higher proportion of patients receiving guselkumab Q4W (60%) and Q8W (51%) vs placebo (30%) achieved a ≥ 20% improvement in the American College of Rheumatology (ACR)20 response. The response rates increased through week 52 (69%-78) and were consistent at week 100 (76%-80%) across all the groups. Similar trends were observed for ACR50, with no new safety signals.
Study details: This post hoc analysis of the phase 3 trials DISCOVER-1 and DISCOVER-2 included 1002 biologic-naive patients with PsA who received 100 mg guselkumab Q4W, 100 mg guselkumab at weeks 0 and 4 and then Q8W, or placebo through week 24 with crossover to 100 mg guselkumab Q4W.
Disclosure: The study was sponsored by Janssen-Cilag Ltd. Four authors were employees of Johnson & Johnson. Several authors received research grants, consulting fees, or had ties with various sources.
