Key clinical point: Ixekizumab was more effective than adalimumab in resolving distal interphalangeal (DIP) joint tenderness, swelling, and adjacent nail psoriasis in patients with psoriatic arthritis (PsA) and DIP joint involvement who nearly invariably had adjacent nail psoriasis.
Major finding: More than 96% of patients with PsA and simultaneous DIP joint involvement reported adjacent nail psoriasis in at least one digit in the finger unit. Ixekizumab vs adalimumab led to greater improvements in DIP involvement and adjacent nail psoriasis as early as week 12 (38.8% vs 28.4%; P < .0001), with improvements sustained up to week 52 (64.9% vs 57.5%; P = .0055).
Study details: This post hoc analysis of the SPIRIT-H2H study included 354 patients with PsA who had simultaneous DIP joint involvement and adjacent nail psoriasis and were randomly assigned to receive ixekizumab or adalimumab.
