Study design details

Main study objective

To understand the patterns of treatment, clinical effectiveness, patient-reported outcomes and treatment adherence among Australian adult patients with RA treated with tofacitinib. Similar data will also be collected for patients treated with bDMARDs to provide descriptive information about clinical management of RA in real-world Australian clinical practice.

Outcomes

(1) To describe tofacitinib treatment patterns among Australian adult patients with RA. (2) To assess the clinical effectiveness of tofacitinib, as defined by disease severity markers and percentage of patients reaching targeted treatment goals, in Australia. (3) To assess patient reported outcomes and treatment adherence in Australian adult patients with RA who are prescribed tofacitinib. (1) To describe bDMARD treatment patterns among Australian adult patients with RA. (2) To assess patient reported outcomes and treatment adherence in Australian adult patients with RA who are prescribed bDMARDs. (3) To describe the safety profile of Australian adult patients with RA who have been prescribed tofacitinib.

Data analysis plan

Patients meeting the inclusion and exclusion criteria described above will be categorised into one of two mutually exclusive drug cohorts, based on the type of DMARD received (tofacitinib or bDMARDs). All continuous variables will be summarised using n (non-missing sample size), mean, standard deviation, median, minimum and maximum. The frequency and percentages (based on the non-missing sample size) or observed levels will be reported for all categorical measures. Descriptive summaries will be produced for each data cut, providing there is sufficient data available, and again at the final analysis. All summaries are descriptive and there are no comparative analyses being undertaken, therefore, no adjustments for multiple data cuts and multiple endpoints are required. Patients who discontinue their index treatment (tofacitinib or bDMARD) will continue to be followed for a period of 1 year.
