Report summary
This report summarizes Pfizer's Type II variation application for Xeljanz (tofacitinib) to update sections 4.8 and 5.1 of its Summary of Product Characteristics (SmPC). The updates incorporate long-term safety and efficacy data from Study A3921145, focusing on polyarticular course Juvenile Idiopathic Arthritis (pJIA) and psoriatic arthritis (PsA) patients. Key safety updates include incidence rates for serious infections, herpes zoster (including multidermatomal HZ), and liver enzyme elevations. Efficacy data is also included to provide a more accurate long-term performance assessment. The report concludes that Xeljanz maintains a positive benefit-risk balance and recommends approval of the variation.
