Abstract

OBJECTIVES: Evaluate the efficacy and safety of anifrolumab in the subpopulation of Japanese patients with systemic lupus erythematosus (SLE) in phase 3 TULIP-2 trial. METHODS: TULIP-2 was a 52-week randomized placebo-controlled trial (N = 362) that evaluated efficacy and safety of anifrolumab 300 mg IV every 4 weeks vs. placebo in patients with moderate to severe SLE who were receiving standard therapy. We performed a post hoc analysis of the primary and key secondary endpoints, and safety, of TULIP-2 in the Japanese subpopulation. RESULTS: In the Japanese subpopulation (anifrolumab, n = 24; placebo, n = 19), the proportion of patients who achieved a British Isles Lupus Assessment Group-based Composite Lupus Assessment response at Week 52 (primary endpoint) was greater in the anifrolumab group vs. placebo [50.0% (12/24) vs. 15.8% (3/19); treatment difference: 34.2%, 95% confidence interval 6.9, 61.5; nominal p = .014]. Improvement in skin activity and flare rates (key secondary endpoints) were favourable for anifrolumab vs. placebo. Consistent with the overall population, anifrolumab had an acceptable safety and tolerability profile. CONCLUSIONS: The efficacy and safety of anifrolumab 300 mg in Japanese patients with SLE was consistent with the demonstrated clinical profile of anifrolumab for the overall TULIP-2 population.
