Introduction: There is limited information on safety events observed for tofacitinib using real-world data that includes an active comparator. In this analysis, we examined the risk of serious infections (SIs) among patients (pts) with ulcerative colitis (UC) initiating tofacitinib or biologics using data from an adjudicated United States (US) medical and pharmacy claims database (Komodo Health).

Methods: Pts with UC initiating a new treatment with tofacitinib, ustekinumab, vedolizumab, or TNFi from 31 May 2018–30 September 2022 were selected. Stabilized inverse probability treatment weights (sIPTW) were calculated using 17 covariates in the main analysis to examine the risk of developing SIs, and an additional 53 covariates in a sensitivity analysis to control for additional comorbidities, UC-related measures, and health care utilization variables. Cox proportional hazards models with sIPTW were used to calculate hazard ratios (HRs) and bootstrapping to calculate 95% confidence intervals (CIs).

Results: Data from UC pts initiating new treatments were included: n=5,171 tofacitinib; n=10,424 ustekinumab; n=17,129 vedolizumab; n=29,872 TNFi. Mean age at index date was 43.1 (+ 15.1) years, and mean follow-up 359.2 (+/- 323.7) days. A greater proportion of pts initiating tofacitinib had used >3 prior biologics (14.8%) compared to ustekinumab (6.8%), vedolizumab (1.4%), and TNFi (1.6%).

The incidence rate of SI (n=1,572 total) per 100 person-years was 2.62 (95% CI 2.17, 3.13) for tofacitinib; 2.73 (95% CI 2.41, 3.08) for ustekinumab; 2.45 (95% CI 2.23, 2.69) for vedolizumab; and 3.25 (95% CI 3.05, 3.46) for TNFi. In analyses adjusting for 70 total covariates, no significant differences in SIs in pts treated with biologics vs. tofacitinib were found (Table).

Discussion: In this large US-based claims analysis that adjusted for many covariates, there was no significant difference in the risk of SIs among pts with UC receiving tofacitinib compared to biologics. These findings have important implications for IBD management.
