Multiple sclerosis (MS) is a complex and heterogeneous disease with a wide range of clinical presentations and treatment responses. This variability makes it difficult to define what constitutes a “responder” to a given MS therapy. As a result, there is a lack of consensus on how to measure treatment efficacy, which can make it challenging to compare different therapies and make treatment decisions.
This workshop aimed to bring together experts in MS research and clinical practice to discuss the challenges of defining responders and non-responders in MS therapies. The goal of the workshop was to develop a set of recommendations for standardising these definitions. The specific objectives of this workshop were:
- To review the current state of the art in defining responders and non-responders in MS therapies
- To discuss the challenges of developing standardised definitions
- To propose a set of recommendations for standardising definitions
- To identify future research directions
