Yuflyma® (Adalimumab), Patient Experience After Switching

Overview

Patient preference and experience can impact patients' adherence and persistence regarding a treatment, especially when switching. A number of factors contribute to this, including their beliefs, fears, expectations, and overall knowledge. This is compounded by the fact that many switched patients are not trained on how to use the new injection device. Specifically, some patients report a degraded experience with current adalimumab biosimilars (40mg/0.8mL) as compared to the originator: injections appear more painful and seem to cause more bruising. Indeed, treatment-related factors such as treatment volume or the presence of citrate have the potential to negatively impact patient experience and contribute to local reactions at or around the injection site, such as pain and swelling. Yuflyma® (CT-P17 adalimumab), developed by Celltrion Inc., is a biosimilar of the anti-TNF treatment adalimumab, having obtained a marketing authorisation from the European Commission on 11th February 2021 (addressed to Celltrion Healthcare). Yuflyma® is the first high-concentration adalimumab biosimilar (40mg/0.4mL) available in France, which makes the product similar to the currently available adalimumab originator formula in terms of drug concentration. Studying patient experience over the course of a switch involves querying patients at the time of prescription, while they are still under the previous treatment, and for the following 3 months, during which they have been able to pick up their prescribed medication from a pharmacy and have started using the new treatment. Describing patient experience over the course of a switch from another adalimumab (originator or biosimilar) to Yuflyma® would contribute to identifying significant factors which contribute to patient experience and satisfaction. Our primary objective is to assess patients' overall satisfaction with the injection after the switch to the high-concentration adalimumab biosimilar Yuflyma®, at 3 months following the initiation, compared to their experience with the previous adalimumab. * Overall satisfaction with the injection (7-level likert) before initiation * Overall satisfaction with the injection (7-level likert) 3 months after initiation
