Key clinical point: Guselkumab effectively resolved dactylitis in the majority of patients with psoriatic arthritis (PsA), with improvements sustained through 1 year, which in turn improved other clinical outcomes.
Major finding: At week 24, a significantly higher proportion of patients receiving guselkumab every 4 or 8 weeks (Q4W or Q8W) vs placebo (63.5% or 59.4% vs 42.2%, respectively; P < .05) achieved dactylitis resolution; approximately 80% of patients receiving guselkumab achieved ≥70% improvement in dactylitis severity score by week 52. Patients with resolved dactylitis at week 24 were more likely to achieve American College of Rheumatology 50 response and other clinical outcomes (P < .05).
Study details: This pooled analysis included 1120 patients with active PsA from the phase 3 DISCOVER-1 and DISCOVER-2 studies who were randomly assigned to receive 100 mg guselkumab Q4W or Q8W or placebo.
