Abstract

Background Secukinumab improved signs and symptoms of ankylosing spondylitis (AS) over 2 years in the MEASURE 2 study (NCT01649375).1,2

Objectives To report the efficacy and safety of secukinumab over 3 years from the MEASURE 2 study.

Methods 219 patients (pts) with active AS were randomised to subcutaneous secukinumab 150mg (72 pts), 75mg (73 pts) or placebo (PBO, 74 pts). At Week (Wk) 16, PBO treated pts were re-randomised 1:1 to secukinumab 150mg or 75mg, irrespective of clinical response. Pts initially randomised to secukinumab and those who switched from PBO to secukinumab at Wk 16 were included in the analysis (secukinumab 150mg, N=106 and secukinumab 75mg, N=105). Outcome measures at Wk 156 included ASAS20 and 40, ASDAS-CRP inactive disease, ASAS5/6, BASDAI, SF-36 PCS and ASAS partial remission. Data are reported as observed. Safety analyses included all pts who received ≥1 dose of secukinumab.

Results At 156 wks, the completion rates for secukinumab 150mg was 81.1% (86/106) and 72.4% (76/105) for 75mg. Higher discontinuation rates for 75mg were in part due to lack of efficacy or patient/guardian decision. Efficacy observed across endpoints from Wks 52 to 156 are summarised in the Table. Higher responses were observed in the 150mg group (Table and Figure). Over the entire study period, the mean exposure [±SD] to secukinumab was 914.3±315.5 days. The exposure-adjusted incidence rates with Any secukinumab for infections/infestations, Crohn's disease, malignant/unspecified tumours and major adverse cardiovascular events were 1.5, 0.6, 0.6 and 0.6 per 100 pt-years, respectively.

Summary of Efficacy Results at Wks 52 and 156

Conclusions Secukinumab 150mg provided sustained improvement in the signs & symptoms along with physical functions with over 80% retention rate through 3 years in pts with AS. Safety profile remained favourable and was consistent with previous reports.1,2
