Sanofi shows how $500M bowel disease bet compares to Merck and Roche's rival assets
The article reports new phase 2 trial data for duvakitug, an experimental anti‑TL1A treatment for ulcerative colitis and Crohn’s disease, which helps compare it to rival candidates and shapes upcoming phase 3 plans.
Patients and clinicians following new treatment options or clinical trials may find the comparative efficacy and subgroup results relevant.
Adult patients with ulcerative colitis or Crohn’s disease interested in emerging therapies or clinical trials, clinicians treating IBD, researchers tracking TL1A programs, and patients on advanced biologic therapies monitoring new options.
What To Know
Sanofi and Teva published phase 2 data for duvakitug (an anti‑TL1A antibody) in ulcerative colitis and Crohn’s disease and presented updated subgroup and secondary endpoint results at the ECCO meeting.
The readout reported endoscopic improvement rates at 14 weeks for low and high doses (45% and 50%) versus 23% for placebo, and discussed placebo‑adjusted deltas compared to rival TL1A programs from Roche (Roivant) and Merck (Prometheus). The companies said the results are informing phase 3 design decisions.
Duvakitug’s phase 2 data included analyses by prior advanced‑therapy exposure (naïve vs experienced) and endoscopic outcomes; Sanofi/Teva reported higher placebo‑adjusted effects in some advanced‑therapy–experienced subgroups. The partners are finalizing a phase 3 plan informed by modeling from this study.
