First Phase 3b study in psoriatic arthritis to evaluate the superiority of an IL-17A and IL-17F inhibitor to an IL-23 inhibitor This first head-to-head study in psoriatic arthritis to use ACR50 at Week 16 as a primary endpoint Study underscores UCB's belief in BIMZELX with top-line results expected in 2026 ATLANTA , Sept. 30, 2024 /PRNewswire/ -- UCB, a global biopharmaceutical company, today announced the start of BE BOLD, a head-to-head Phase 3b study, comparing BIMZELX ® (bimekizumab-bkzx), an interleukin (IL)-17A and IL-17F inhibitor, with SKYRIZI ® (risankizumab), an IL-23 inhibitor, in the treatment of adults with active psoriatic arthritis (PsA). BE BOLD is the first head-to-head study in PsA evaluating the superiority of an IL-17A and IL-17F inhibitor to an IL-23 inhibitor.
"The conduct of head-to-head, evidence-based, clinical studies in psoriatic arthritis is important since they add to the existing scientific evidence available to healthcare professionals and patients and can help to make informed treatment decisions," said Philip J. Mease , MD, Director of Rheumatology Research at the Providence Swedish Medical Center and Clinical Professor at the University of Washington School of Medicine in Seattle, WA , U.S.
"This is the first Phase 3b head-to-head study in psoriatic arthritis to utilize the primary endpoint of ACR50 at Week 16. This robust assessment is set to provide a meaningful comparison of bimekizumab vs. risankizumab on inflamed joints, one of the are.
