Equillium, Inc. announced positive topline results on February 6, 2025, from its Phase 2 study evaluating itolizumab in patients with moderate to severe ulcerative colitis (UC). The study demonstrated clinical efficacy after 12 weeks of treatment. Itolizumab achieved a clinical remission rate of 23.3% in UC patients, which compares favorably to 20.0% for adalimumab and 10.0% for placebo in the study. The drug also met the key secondary endpoint of endoscopic remission, with a rate of 16.7%, matching adalimumab and surpassing placebo's 6.7%. These results highlight the therapeutic potential of itolizumab in a new indication, suggesting a broader application for the anti-CD6 monoclonal antibody. The data supports further development of itolizumab for inflammatory bowel diseases.
