Targeting the TL1A pathway in inflammatory bowel disease: mechanistic insights and emerging therapeutic pipeline. (PubMed, Inflamm Bowel Dis) - "Three anti-TL1A monoclonal antibodies (tulisokibart, afimkibart, and duvakitug) have advanced to phase 3 trials across multiple global programs, with phase 2 clinical remission rates of 26%-48% in ulcerative colitis (placebo-adjusted differences 15-26 percentage points) and endoscopic response rates of 26%-48% in Crohn's disease, alongside favorable safety profiles...The pipeline has expanded to at least 19 development programs, including extended half-life antibodies (XmAb942, SPY002, and BCD-261), bispecifics combining TL1A with IL-23 or α4β7 (RO7837195, XmAb412, LQ080, and ALX001), a first-in-class oral anti-TL1A nanobody, and a first-in-class DR3 receptor antagonist (SL-325). We discuss therapeutic positioning and timing, the opportunity in acute severe UC, and the unusual standing of IBD as the lead indication for this mechanism class."

Preclinical evaluation of a TL1A × IL-23 bispecific antibody for immune-mediated inflammatory diseases (ECCO-IBD 2026) - "The favorable PK profile supports extended dosing intervals, a key benefit for patients with chronic IMIDs. These findings warrant further development of ALX001 for the treatment of IMIDs."
