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.

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.

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.

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.

Reinisch, et al. show that filgotinib treatment has no effect on semen parameters for men with active inflammatory diseases. This contrasts with pre-clinical studies that showed fertility issues in male animals.
