Key clinical point: Brepocitinib, the tyrosine kinase 2/Janus kinase 1 inhibitor, was superior to placebo in reducing signs and symptoms of psoriatic arthritis (PsA) and was well-tolerated throughout the 52-week study period.
Major finding: At week 16, American College of Rheumatology 20 response was achieved by a significantly higher proportion of patients receiving brepocitinib at doses of 30 mg (66.7%; P = .0197) and 60 mg (74.6%; P = .0006) compared with placebo (43.3%), with the response being maintained through week 52. Overall, 12 serious adverse events were reported in the brepocitinib arms (30 and 60 mg) by week 52. No deaths were reported.
Study details: Findings are from a phase 2b, dose-ranging, parallel treatment group trial including 218 patients with active PsA who were randomly assigned to receive either brepocitinib (60, 30, or 10 mg once daily) or placebo.
Disclosures: This study was sponsored by Pfizer Inc. Several authors declared being current or former employees and shareholders of Pfizer. The other authors reported ties with various sources, including Pfizer.
