Highlights

  • Tulisokibart, an anti-TL1A monoclonal antibody, demonstrates endoscopic and clinical efficacy in phase 2 trials for both Crohn’s disease and ulcerative colitis refractory to standard therapies.
  • In Crohn’s disease, 26% achieved endoscopic response at week 12; in ulcerative colitis, clinical remission was significantly higher with tulisokibart versus placebo (26% vs. 1%).
  • Safety profile was favorable, with most adverse events mild to moderate and no deaths reported.
  • Ongoing phase 3 trials will further assess long-term efficacy and safety.
