Introduction
Tofacitinib is an oral small molecule Janus kinase inhibitor for the treatment of ulcerative colitis (UC). The safety of tofacitinib was evaluated in the Overall Cohort, which consisted of 6 studies: 4 randomised, placebo-controlled Phase (P)2/3 studies (NCT00787202; NCT01465763; NCT01458951; NCT01458574), an open-label, long‑term extension study (NCT01470612) and a randomised P3b/4 study (NCT03281304). We report final safety analyses from the tofacitinib UC clinical programme of ≤9.2 years of tofacitinib exposure (cut off date: 18 April 2022).
Aims & Methods
This analysis included 1157 patients (pts) receiving tofacitinib 5 or 10 mg twice daily (BID; predominant dose [PD]) in the Overall Cohort and a previously reported 52-week Maintenance Cohort.1,2 Proportions and incidence rates (IRs; unique pts with events/100 pt-years of exposure) were evaluated for deaths and adverse events of special interest (AESI): serious infections; herpes zoster (HZ); opportunistic infections (OIs); malignancies (excluding non‑melanoma skin cancer [NMSC]); NMSC; major adverse cardiovascular events (MACE); deep vein thrombosis (DVT); pulmonary embolism (PE); and gastrointestinal (GI) perforations.
Results
In the Overall Cohort, 1157 pts received ≥1 dose of tofacitinib 5 or 10 mg BID; 938 (81.1%) received a PD of 10 mg BID; 552 (47.7%) pts had received tofacitinib for ≥2 years. Median treatment duration was 1.7 years (mean 2.8; range 0.0–9.2). IRs (95% CI) for all tofacitinib in the Overall Cohort (Table): deaths 0.24 (0.10, 0.48); serious infections 1.80 (1.37, 2.32); HZ (non-serious and serious) 3.24 (2.63, 3.94); serious HZ 0.24 (0.10, 0.48); OIs 0.96 (0.65, 1.36); malignancies (excluding NMSC) 0.88 (0.59, 1.26); NMSC 0.71 (0.45, 1.07); MACE 0.27 (0.12, 0.52); DVT 0.06 (0.01, 0.22); PE 0.18 (0.07, 0.40); and GI perforations 0.09 (0.02, 0.27).

Conclusion
IRs for AESI remained stable over an extended period of time (≤9.2 years) with the inclusion of the P3b/4 final data and were consistent with prior Overall Cohort analyses (≤7.8 years).1,2 The safety profile of tofacitinib in the UC clinical programme was consistent with that observed in other indications.3,4
