Key clinical point : Among biologic-naive individuals with psoriatic arthritis (PsA), interleukin-12/23 (IL-12/23) antagonists were less effective than tumor necrosis factor-alpha (TNF-α) inhibitors. PDE4 treatment was significantly less effective than TNF-α inhibitors among biologic-experienced individuals.
Major finding: Among biologic-naïve individuals, IL-12/23 was less effective than TNF-α ( adjusted relative risk [aRR], 0.63; 95% confidence interval [CI], 0.45-0.89), whereas PDE4 treatment was less effective than TNF-α inhibitor among biologic-experienced individuals (aRR, 0.67; 95% CI, 0.46-0.96).
Study details: Findings are from a retrospective study of 2,730 commercially insured and Medicare Advantage beneficiaries with PsA.
