A randomized Phase II study of efmarodocokin alfa, an interleukin-22 agonist, versus vedolizumab in patients with ulcerative colitis

Clinical Gastroenterology and Hepatology 2025;23:1387–1397 doi: 10.1016/j.cgh.2024.11.013

Danese et al. observed that efmarodocokin alfa did not demonstrate efficacy compared to the PBO, and this Phase II study ended early for futility; however, there was evidence of target engagement (skin AEs, regenerating islet derived protein 3-alpha).

This interim analysis by Panaccione et al. supports the positive long–term risk–benefit profile for UPA 15mg and 30mg among patients with moderately to severely active UC. U–ACTIVATE is a Phase 3 LTE study evaluating the long-term safety and efficacy of UPA in patients with moderately to severely active UC who enrolled in the preceding induction and maintenance studies. Panaccione et al. reported the interim results from the U-ACTIVATE study after approximately 3 years of total treatment, showing that the risk–benefit profile of UPA in patients with moderately to severely active UC is favourable.
