Key clinical point: Guselkumab treatment led to durable improvements in key Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (PsA)-recognized domains through 2 years and showed a consistent safety profile in biologic or Janus kinase inhibitor-naive patients with active PsA.
Major finding: At week 100, more than 50% of patients receiving guselkumab (100 mg every 4 or 8 weeks) achieved achieved a low PsA Disease Activity Index, had enthesitis resolution, dactylitis resolution, and 100% improvement in Psoriasis Area and Severity Index. No new safety signals were observed.
Study details: This post hoc analysis included 442 biologic or Janus kinase inhibitor-naive patients with active PsA and previous inadequate response or intolerance to standard nonbiologics who received 100 mg guselkumab every 4 or 8 weeks through week 100.
