Study description

Tofacitinib citrate (Xeljanz®) is an oral Janus kinase inhibitor approved by the European Commission (EC) for the treatment of adults with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ulcerative colitis (UC). To minimise important potential and identified risks associated with the use of tofacitinib, the Marketing Authorisation Holder (MAH) implemented additional risk minimisation measures (aRMMs). This protocol describes a drug utilisation study to assess prescribing patterns of tofacitinib and whether there is evidence that prescribers are following the screening and monitoring recommendations and limitations for use included in the aRMM materials for patients prescribed tofacitinib, as well as any potential off-label use of tofacitinib, contraindicated use, and use with concomitant medications not compatible with tofacitinib. Additionally, as a result of the 2019 benefit-risk reassessment requested by the EC pursuant to Article 20 of Regulation (EC) No 726/2004, as well as the 2021 signal evaluation procedure, the MAH will evaluate healthcare professionals’ compliance with the new Pharmacovigilance Risk Assessment Committee (PRAC) recommendations and limitations for use implemented after the 2019 Article 20 referral to minimise the risk of venous thromboembolism (VTE), use in elderly patients aged ≥65 years, and mortality, and after the signal evaluation procedure to assess use in patients with cardiovascular (CV) risk factors and use in patients with malignancy risk factors.
