Background
Ankylosing spondylitis (AS) is a chronic inflammatory condition with pain, stiffness and fatigue reported as the most troubling symptoms. Early and sustained relief of these symptoms is essential for effective management. Secukinumab provided sustained relief from pain and fatigue in AS patients over 2 years in the MEASURE 2 study. We report the effect of subcutaneous secukinumab 150 mg on key clinical symptoms (pain, morning stiffness and fatigue) in AS patients over 208 weeks in MEASURE 2.
Methods
This post-hoc analysis of MEASURE 2 assessed mean change from baseline to Week 208 in total and nocturnal back pain scores (by VAS [0-100]; ASAS outcome component), overall level of spinal pain (neck, back or hip) from BASDAI scores, and morning stiffness (overall level; mean of question 5 and 6 of BASDAI score). Additionally, the SF-36 physical component summary score, overall level of fatigue (BASDAI question 1), FACIT-Fatigue score and patients meeting minimal clinically important difference (MCID) criteria across multiple clinical domains were assessed. Data are shown for patients originally randomised to secukinumab 150 mg and placebo. Data are reported as observed for the overall population and by prior TNF inhibitor (TNFi) therapy status (naive vs inadequate response [IR]).
Results
Baseline characteristics were comparable across secukinumab 150 mg (N = 72) and placebo (N = 74) groups; total mean back pain score was 67.7±17.79, nocturnal back pain score was 64.9±19.58 and morning stiffness was 6.5±2.11. Secukinumab 150 mg-treated patients reported rapid and early reductions in pain scores by Week 4, which were sustained through Week 208 (Table 1). Improvements with secukinumab 150 mg were reported for all key clinical symptoms by Week 4, which were sustained at Week 208. A higher proportion of secukinumab 150 mg-treated patients met MCID criteria at Week 16 vs placebo across multiple clinical domains, which was sustained or further improved through Week 208. Improvements were observed in TNFi-naive and -IR patients, with a greater magnitude of improvement in TNFi-naive patients.
Conclusion
Secukinumab 150 mg was associated with rapid and clinically meaningful improvements in total and nocturnal back pain, morning stiffness and fatigue, with improvements sustained over 4 years of treatment.
