Short-term effectiveness and safety of tofacitinib in ulcerative colitis-real world data from tertiary medical centers in Israel

A B S T R A C T 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. (c) 2021 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd. All rights reserved.

Automated summary

Tofacitinib showed effectiveness and safety in treating moderate to severe ulcerative colitis in Israeli patients, achieving corticosteroid-free remission in about 20% of patients with extensive biologics experience. Despite some patients continuing to use tofacitinib at 26 weeks, it was well tolerated and safe. Earlier use of tofacitinib in the treatment algorithm may lead to improved outcomes.
