Sands et al. evaluated tamuzimod, a selective sphingosine 1-phosphate receptor 1 modulator, in patients with moderately-to-severely active UC. At Week 13, clinical remission (defined as an MMS stool frequency subscore of ≤1, rectal bleeding subscore of 0, and endoscopic subscore ≤1, excluding friability) was achieved by 28% and 24% of patients receiving tamuzimod 60 mg and 30 mg, respectively, compared with 11% in the placebo group. The treatment was well tolerated; most AEs were mild or moderate.

Risankizumab for Ulcerative Colitis Two Randomized Clinical Trials

JAMA. 2024;332:881-897 doi: 10.1001/jama.2024.12414

Louis et al. demonstrated risankizumab to significantly improve clinical remission rates compared to placebo in both an induction trial and in a maintenance trial for patients with moderately to severely active ulcerative colitis.

Filgotinib (FIL) 200mg was associated with numerical reductions in the number of draining perianal fistulas based on combined clinical and MRI findings compared with placebo. Reinisch et al. reported a numerically higher proportion of patients achieving the primary endpoint of a combined fistula response and/or remission at Week 24 with FIL 200mg compared with placebo.

This post hoc analysis provides additional support for the utility of risankizumab therapy in patients with moderately to severely active CD. Investigators examined the efficacy of risankizumab for providing early symptom relief, along with the prognostic value of early symptom relief for achieving future clinical and endoscopic endpoints.

The authors highlighted a significantly greater clinical remission rate at Week 52 for vedolizumab SC versus placebo in patients with moderately to severely active CD. This study aimed to report results from VISIBLE 2 which evaluated a new SC vedolizumab formulation as maintenance treatment in adults with moderately to severely active CD.

Guselkumab induced greater clinical and endoscopic improvements in patients with Crohn’s disease versus placebo, with a favourable safety profile in this Phase 2 trial by Sandborn, et al.

Risankizumab was effective and well tolerated as induction therapy in patients with moderately to severely active Crohn’s disease, though there were no significant differences in efficacy between 600mg and 1200mg doses.

Etrasimod demonstrated significant efficacy in achieving clinical remission, and was well tolerated compared to placebo in an induction and maintenance therapy.

Mirikizumab as induction and maintenance therapy for ulcerative colitis

N Engl J Med 2023;388(26):2444–2455 doi: 10.1056/NEJMoa2207940

Mirikizumab was more effective than placebo in inducing and maintaining clinical remission in patients with moderately to severely active ulcerative colitis. D’Haens, et al. also noted that opportunistic infections and cancer developed in a small number of mirikizumab-treated patients.

The results of two induction studies (UC1 and UC2) and a maintenance study (UC3) show upadacitinib superiority to placebo in treating ulcerative colitis (UC). Rates of clinical remission were significantly higher for all upadacitinib doses versus placebo in all three studies.
