Abstract

Aim: To evaluate efficacy and safety of secukinumab in Asian patients with active ankylosing spondylitis (AS) via a pooled subgroup analysis from two phase 3 studies, MEASURE 1 (NCT01358175) and MEASURE 2 (NCT01649375). Methods: In MEASURE 1, patients were randomized to intravenous secukinumab 10 mg/kg or placebo at baseline, Weeks 2 and 4, followed by subcutaneous (s.c.) secukinumab 150 mg, 75 mg or placebo every 4 weeks (q4w) at Week 8. In MEASURE 2, patients were randomized to s.c. secukinumab 150 mg, 75 mg or placebo at baseline, Weeks 1, 2 and 3, and q4w starting at Week 4. Efficacy outcomes were SpondyloArthritis International Society (ASAS) 20/40, high-sensitivity C-reactive protein (hsCRP), ASAS5/6, Bath Ankylosing Spondylitis Disease Activity Index, Short Form-36 physical component summary, AS quality of life (QoL), ASAS partial remission, and Ankylosing Spondylitis Disease Activity Score – CRP at Weeks 16 and 52. Due to lack of efficacy, the secukinumab 75 mg dose in MEASURE 2 was excluded from this pooled Asian subgroup analysis. Safety analysis included patients who received ≥ 1 dose of study treatment. Results: Of 517 patients enrolled into the MEASURE studies, 69 (13.3%) were Asians: 46 in pooled secukinumab and 23 in placebo. At Week 16, ASAS20/40 responses in Asian patients were 69.6%/43.5% with pooled secukinumab versus 26.1%/17.4% with placebo, which were comparable with rates reported in the overall study population. Secukinumab improved predefined efficacy endpoints at Week 16, with responses sustained through Week 52. Secukinumab was well tolerated in Asian patients, with a safety profile consistent with that reported in the overall study population. Conclusion: Secukinumab improved signs and symptoms, physical function, and disease-specific QoL in Asian patients with active AS.
