Abstract
PurposeThis article describes preclinical development of cell-based medicinal products for European markets and discusses European regulatory mechanisms open to developers to aid successful product development. Cell-based medicinal products are diverse, including cells that are autologous or allogeneic, have been genetically modified, or not, or expanded ex vivo, and applied systemically or to an anatomical site different to that of their origin; comments applicable to one product may not be applicable to others, so bespoke development is needed, for all elements - quality, preclinical and clinical.MethodsAfter establishing how the product is produced, proof of potential for therapeutic efficacy, and then safety, of the product need to be determined. This includes understanding biodistribution, persistence and toxicity, including potential for malignant transformation. These elements need to be considered in the context of the intended clinical development.ResultsThis article describes regulatory mechanisms available to developers to support product development that aim to resolve scientific issues prior to marketing authorization application, to enable patients to have faster access to the product than would otherwise be the case.ConclusionsDevelopers are encouraged to be aware of both the scientific issues and regulatory mechanisms to ensure patients can be supplied with these products.
Highlights
MethodsAfter establishing how the product is produced, proof of potential for therapeutic efficacy, and safety, of the product need to be determined
In the development of cell-based medicinal products, data needs to be generated to support progression from testing in animals into testing in patients
Developers are encouraged to be aware of both the scientific issues and regulatory mechanisms to ensure patients can be supplied with these products
Summary
After establishing how the product is produced, proof of potential for therapeutic efficacy, and safety, of the product need to be determined. This includes understanding biodistribution, persistence and toxicity, including potential for malignant transformation. These elements need to be considered in the context of the intended clinical development
