Merck & Company IncMerck's tulisokibart met primary endpoint in Phase 3 UC study, a positive drug development milestone.

Merck announced that its investigational anti-TL1A monoclonal antibody tulisokibart met the primary endpoint of clinical remission at week 12 in the Phase 3 ATLAS-UC induction-only study for moderately to severely active ulcerative colitis. The study, one of two independent studies in the ATLAS-UC program, also met key secondary endpoints including endoscopic improvement, clinical response, and histologic-endoscopic mucosal improvement. No safety concerns were identified, consistent with earlier Phase 2 data. Merck stated that tulisokibart is the first anti-TL1A biologic to demonstrate clinical remission in a Phase 3 trial for this condition, and results will be presented alongside the ongoing induction and maintenance study at a future scientific congress.
