OBJECTIVES: To evaluate improvement in pain and fatigue in ankylosing spondylitis (AS) patients treated with secukinumab over 2 years (MEASURE 2 study). METHODS: Patients with active AS were randomised to receive secukinumab 150 mg, 75 mg, or placebo weekly until Week 4, and every 4 weeks thereafter. This post hoc analysis included assessment of spinal and nocturnal back pain, FACIT-Fatigue, and association between pain and either FACIT-Fatigue or ASQoL item 5 (sleep quality) for the approved secukinumab 150 mg dose in the overall population, and stratified by baseline high-sensitivity C-reactive protein (hsCRP) levels (normal [<5 mg/L] or elevated [≥5 mg/L]) or prior TNF inhibitor therapy status (TNFi-naïve or inadequate response [TNFi-IR]). RESULTS: Secukinumab-treated patients reported rapid improvement in pain and fatigue scores in overall population by Weeks 1 and 4, respectively; this trend of improvement was also observed irrespective of baseline hsCRP levels or prior TNFi therapy. Mean change at Week 16 in spinal/nocturnal pain (secukinumab vs. placebo) for the subgroups were -34.6/-30.2 vs. -16.6/-10.0, p<0.05/0.01 (normal hsCRP); -26.7/-31.6 vs. -7.8/-9.3, p<0.001/0.0001 (elevated hsCRP); -33.2/-35.4 vs. -13.2/-14.9, both p<0.0001 (TNFi-naïve); and -22.5/-22.8 vs. -9.4/-4.0, p=0.06/p<0.01 (TNFi-IR). FACIT-Fatigue was 7.1 vs. 3.3, p=0.15 (normal hsCRP); 8.7 vs. 3.6, p<0.05 (elevated hsCRP); 10.0 vs. 5.2, p<0.05 (TNFi-naïve); and 5.7 vs. 0.5, p=0.06 (TNFi-IR). These improvements were sustained or further improved through Week 104. CONCLUSIONS: Secukinumab provides rapid and sustained relief of pain and fatigue over 2 years in patients with AS regardless of baseline hsCRP levels and prior TNFi therapy.
