UCB, a global biopharmaceutical company, announced positive top-line interim analysis results from the Phase III BE MOBILE 2 study, which is evaluating the efficacy and safety of Bimzelx (bimekizumab) in adults with active ankylosing spondylitis, also known as radiographic axial spondyloarthritis (r-axSpA).

BE MOBILE 2 is one of two Phase III studies evaluating bimekizumab across the full spectrum of axSpA disease, which includes both radiographic and non-radiographic (nr)-axSpA.

The BE MOBILE 2 study met its primary endpoint, as measured by the proportion of patients who achieved the Assessment of SpondyloArthritis International Society 40 (ASAS40) response at week 16, when compared to placebo. ASAS40 measures improvements in disease across different domains, including patient global assessment of disease activity, spinal pain, physical function and inflammation. The primary endpoint used in this study, ASAS40, set a high threshold for improvement in patient-reported outcomes, i.e., at least a 40 percent improvement relative to baseline.

The study also met all ranked secondary endpoints, including significant improvements with bimekizumab over placebo at week 16 in patient-reported disease activity, as measured by the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI); achievement of ASAS partial-remission (PR) and Ankylosing Spondylitis Disease Activity Score (ASDAS) Major Improvement (MI); and the nocturnal spinal pain score.

“Ankylosing spondylitis is a painful, chronic, inflammatory rheumatic disease that often starts in young adulthood. The encouraging top-line Phase III results are consistent with the Phase II findings and suggest that bimekizumab has the potential to deliver clinically meaningful improvements in the key signs and symptoms of the disease,” said Emmanuel Caeymaex, Executive Vice President, Immunology Solutions and Head of U.S., UCB. “Today’s findings for bimekizumab in ankylosing spondylitis follow closely behind the positive results in psoriatic arthritis reported last month and reinforce our continued commitment to advancing standards of care.”
