Worth, et al. found that namilumab did not show efficacy compared with placebo in patients with active axSpA, but the treatment was generally well tolerated. An unusually high proportion of ASAS20 responders at Week 12 were observed in the placebo group, which had a small sample size compared to the namilumab arm.

Bimekizumab (BKZ) treatment led to early improvements in physical function, sleep, work productivity, and overall health-related quality of life at Week 16 in patients across the full axSpA disease spectrum, which were sustained through Week 52. Dubreuil et al. investigated treatment impact over one year using BASFI, MOS-Sleep-R, SF-36 PCS/MCS, WPAI:axSpA, and ASQoL scores in patients with both non-radiographic and radiographic axSpA.

Bimekizumab may therefore offer patients with axSpA an effective treatment option with a novel mode of action.
