Key clinical point: In patients with psoriatic arthritis (PsA), year-long treatment with interleukin-17 inhibitors (IL-17i) and IL-23(p19) inhibitors (IL23-[19]i), led to comparable drug survival and clinical response outcomes as tumor necrosis factor inhibitor (TNFi) treatment.
Major finding: At 12 months, the drug withdrawal rates for IL-17i (hazard ratio [HR] 1.36; 95% CI 0.59-3.14) and IL23-(19)i (HR 0.56; 95% CI 0.10-3.24) were comparable with those for TNFi. Moreover, the proportion of patients who achieved ≥50% improvement in the American College of Rheumatology scores was similar across the IL-17i, IL-23(19)i, and TNFi groups (19%, 29%, and 19%, respectively).
Study details: Findings are from a target trial emulation study including 109 patients with PsA who presented with peripheral manifestations and initiated either TNFi (n = 75), IL-7i (n = 26), or IL-23(19)i (n = 8).
