Study design details

Main study objective

What are the incidence rates of safety events of interest in adult ulcerative colitis (UC) patients aged ?18 years treated with tofacitinib in routine clinical care, as compared to the incidence rates in UC patients treated with other approved systemic agents, and UC patients naïve to biologics and immunomodulators/immunosuppressants (hereafter referred to as immunosuppressants)?

Outcomes

Estimate the incidence rates of malignancy and VTE (deep venous thrombosis DVT and pulmonary embolism PE) among adult UC patients years who initiate tofacitinib in the course of routine clinical care, as well as the incidence rates in UC patients treated with other approved systemic agents such as biologics and immunosuppressants, and in UC patients naïve to biologics and immunosuppressants, Estimate incidence rates of other safety events among adult UC patients who initiate tofacitinib in the course of routine clinical care, in UC patients treated with other approved systemic agents, and in comparator cohorts. Estimate incidence rates of primary and secondary safety events of interest stratified by tofacitinib dose.

Data analysis plan

Baseline demographic and clinical characteristics for each cohort, including proportion of patients with ?1 VTE risk factors will be described. For all the safety events of interest, descriptive statistics, counts and proportions, unadjusted cumulative incidence proportions, and crude incidence rates (i.e. number of events per person-years) and age/sex standardized incidence rates with associated 2-sided 95% confidence intervals will be calculated as appropriate. The estimated incidence rates will be based on survival analysis of time to first event based on an index date defined for each cohort with appropriate censoring rules applied for those who do not experience an event by end of follow-up period.
