Abstract

Background: We sought to define the effectiveness and safety of tofacitinib in a real-world (RW) cohort of Israeli patients with moderate to severe ulcerative colitis (UC).

Methods: This was a multi-center retrospective observational cohort study (2019-2020) to assess the effectiveness and safety of tofacitinib induction and maintenance therapy up to 26 weeks. Clinical response and remission were defined as a reduction in Simple Clinical Colitis Activity Index (SCCAI) or partial Mayo score (PMS) of ≥3 points, and SCCAI ≤2 or a PMS ≤1, respectively.

Results: We included 73 patients, 47% male; median age 26 years [IQR: 19.5-39.5], disease duration 7 years [IQR: 2.5-14.5], follow-up 7.1 months [IQR: 3-12], 91% biologics-experienced, and 74% ≥ 2-biologics. Half of patients used concomitant corticosteroids (CS). Overall, 56.1% discontinued therapy due to either lack of response and/or adverse events (AEs), median time to discontinuation - 9.7 months [IQR 3.4-16]. Overall, response, remission, and CS-free-remission were achieved in 47.6%, 20.6%, and 17.5% of patients, respectively. At early maintenance (week 26), response, remission, and CS-free-remission were achieved in 65%, 22.5%, and 20% of patients, respectively. At week 26, tofacitinib 10 mg BID was still used in 43%. Seventeen patients (23.2%) had an adverse event including herpes zoster- 2.7%, hospitalization- 12.3%, and colectomy- 2.7%.

Conclusions: Tofacitinib was effective in achieving CS-free-remission in about 1/5 of highly biologics -experienced patients with UC. Despite a considerable proportion of patients maintained on tofacitinib 10 mg bid, it was well tolerated and safe. Earlier positioning of tofacitinib in the therapeutic algorithm may result in improved outcomes.
