Tofacitinib for Biologic-Experienced Hospitalized Patients With Acute Severe Ulcerative Colitis: A Retrospective Case-Control Study.

BACKGROUND & AIMS: Despite rescue therapy, more than 30% of patients with acute severe ulcerative colitis (ASUC) require colectomy. Tofacitinib is a rapidly acting Janus kinase inhibitor with proven efficacy in ulcerative colitis. Tofacitinib may provide additional means for preventing colectomy in patients with ASUC. METHODS: A retrospective case-control study was performed evaluating the efficacy of tofacitinib induction in biologic-experienced patients admitted with ASUC requiring intravenous corticosteroids. Tofacitinib patients were matched 1:3 to controls according to gender and date of admission. Using Cox regression adjusted for disease severity, we estimated the 90-day risk of colectomy. Rates of complications and steroid dependence were examined as secondary outcomes. RESULTS: Forty patients who received tofacitinib were matched 1:3 to controls (n = 113). Tofacitinib was protective against colectomy at 90 days compared with matched controls (hazard ratio [HR], 0.28, 95% confidence interval [CI], 0.10-0.81; P = .018). When stratifying according to treatment dose, 10 mg three times daily (HR, 0.11; 95% CI, 0.02-0.56; P = .008) was protective, whereas 10 mg twice daily was not significantly protective (HR, 0.66; 95% CI, 0.21-2.09; P = .5). Rate of complications and steroid dependence were similar between tofacitinib and controls. CONCLUSIONS: Tofacitinib with concomitant intravenous corticosteroids may be an effective induction strategy in biologic-experienced patients hospitalized with ASUC. Prospective trials are needed to identify the safety, optimal dose, frequency, and duration of tofacitinib for ASUC.

Efficacy of Induction Therapy With High-Intensity Tofacitinib in 4 Patients With Acute Severe Ulcerative Colitis.

As many as 25% of patients diagnosed with ulcerative colitis are hospitalized with an episode of acute severe ulcerative colitis (ASUC).1 The standard of care for patients hospitalized with ASUC relies on rapid induction with intravenous (IV) corticosteroids. Up to 30% of patients do not respond to corticosteroids alone.2 Rescue therapy with infliximab or cyclosporine has been shown to reduce rates of colectomy to 20% by 90 days.3,4 This still represents a significant rate of treatment failure, which leads to an unplanned and irreversible surgery. In recent years, increasing numbers of patients admitted with ASUC have already failed infliximab therapy, highlighting the need for additional treatment options for these patients. Tofacitinib is a rapidly acting, oral, small-molecule Janus kinase inhibitor that was recently approved by the Food and Drug Administration for treatment of ulcerative colitis.5 We present the first reported use of off-label, high-intensity tofacitinib in 4 patients admitted to our institution with ASUC predicted to fail medical management.
