RMD OpenPublished Secondary analysis of the BE MOBILE 1 and 2 randomised trials

Authors' conclusion

Bimekizumab treatment led to early improvements in physical function, sleep, work productivity and overall HRQoL at Week 16 in patients across the full axSpA disease spectrum. Improvements were sustained to Week 52.

Primary result

As reported in the abstract

Physical functioning, sleep, work productivity and health-related quality of life (HRQoL) (BASFI, MOS-Sleep-R Index II, WPAI:axSpA, SF-36 PCS/MCS, ASQoL) · Week 16
Significantly greater improvement from baseline vs placebo in Bath Ankylosing Spondylitis Functional Index (BASFI), SF-36 PCS and Ankylosing Spondylitis Quality of Life (ASQoL)
p<0.001

Further findings

BASFI ≤4 and meaningful improvements in SF-36 PCS and ASQoL in bimekizumab-treated patients · Week 52

Responses sustained or further improved; achieved by bimekizumab-treated patients regardless of original randomisation
