Peyrin-Biroulet et al. evaluated the efficacy and safety of etrasimod in patients with moderately to severely active isolated proctitis, demonstrating significant improvement in clinical outcomes compared to placebo. The study reported a favourable safety profile, making etrasimod a viable treatment option for this population.

Upadacitinib Induction and Maintenance Therapy for Crohn’s Disease

N Engl J Med 2023; 388:1966–1980 doi: 10.1056/NEJMoa2212728

Upadacitinib was associated with higher percentages of remission and endoscopic response regardless of previous failure of biologic therapy. This paper reports the Phase 3 efficacy and safety results of upadacitinib in patients with moderate-to-severe Crohn’s disease.

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

This post-hoc analysis of 31 clinical trials in ulcerative colitis, rheumatoid arthritis and psoriatic arthritis concludes that combined influenza adverse event incidence rates were highest in ulcerative colitis, while in each indication they were generally similar across tofacitinib, placebo, and comparator groups.

June 2022

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.

May 2022

Maintenance treatment with risankizumab was associated with an improvement in coprimary endpoints of clinical remission and endoscopic response in patients with Crohn’s disease compared with placebo.

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.

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.

Tofacitinib as induction and maintenance therapy for ulcerative colitis

N Engl J Med. 2017 May 4;376(18):1723-1736. DOI 10.1056/NEJMoa1606910

Tofacitinib, at a dose of 10 mg twice daily, was more effective than placebo for induction of remission and mucosal healing in patients with moderately to severely active ulcerative colitis. Furthermore, maintenance therapy with tofacitinib, at a dose of either 5 mg or 10 mg twice daily, was more effective than placebo in sustaining remission and mucosal healing.
