The COAST-X trial assessed the impact of ixekizumab on functioning and health in patients with active nonradiographic axial spondyloarthritis over 52 weeks, comparing it to placebo.
Ixekizumab treatment led to significant improvements in self-reported health scores, particularly in physical functioning, pain, and overall health status, with better results in patients receiving treatment every 2 weeks.
Patients on ixekizumab reported notable enhancements in quality of life measures (EQ-5D-5L) compared to placebo, showing sustained benefits by week 52.
