FDA, EMA Rare Diseases Cluster
FDA and the European Medicines Agency (EMA) are establishing a joint cluster on rare diseases to share scientific evaluation of various aspects of drug development for rare diseases. A document on terms of reference for the cluster says that the aspects include selection and validation of trial endpoints, potential trial designs in small populations, opportunities for regulatory flexibility (approval supported by other than two adequate and well-controlled studies and/or use of a novel endpoint), determination of safety populations, evaluation of pre-clinical data needed to support human trials, and design and conduct of post-marketing studies especially in the case of accelerated approval (FDA) and conditional/exceptional approval (EMA) or breakthrough designation (FDA) and PRIME designation (EMA).
“The main mechanism to achieve these goals will be regularly scheduled teleconferences,” the document says, “including individuals from review divisions and therapeutic teams, for exchange of information and experiences. It may be appropriate to agree to additional in-depth discussions on specific topics during separate ad hoc teleconferences when it might be relevant to include participation of appropriate EMA/FDA staff members.”
Cluster participants are to discuss and determine which topics will be discussed at this cluster and which will be deferred to other platforms/clusters such as pediatric, oncology, and pharmacovigilance-related topics.
