Key clinical point: Among biologic-naive, guselkumab-treated patients with psoriatic arthritis (PsA), enthesitis resolution (ER) was associated with dactylitis resolution (DR), and those achieving ER or DR showed improvements in patient-reported outcomes.
Major finding: At weeks 24, 52, and 100, guselkumab-treated patients who achieved DR were more likely to achieve ER, and vice versa (all P < .05). At week 24, a higher proportion of patients who did vs did not achieve ER reported minimal pain (30%-45% vs 11%-21%; all P < .001), with similar pain outcomes in patients who did vs did not achieve DR.
Study details: This post hoc analysis included 739 biologic-naive patients with PsA who were randomly assigned to receive guselkumab (100 mg every 4 or 8 weeks) or placebo with crossover to guselkumab (100 mg every 4 weeks) at week 24, of whom 68.6% and 44.9% of patients had enthesitis and dactylitis, respectively.
