Product Development

Most cell and gene therapy products are regulated as medicinal products in the EU and the US; as such their development must result in data that confirm quality, safety and efficacy.  
One of the key objectives of
 , aside from demonstration of clinical efficacy, is to fully understand the characteristics of the product and the process used to make it. Characterisation is central to product development, this figure provides an overview of the scope of characterisation activities and how they interrelate.

Effective development processes provide all the tools necessary to implement changes, and these tools are a result of thorough characterisation.  Implementation of changes to the manufacture of medicinal products requires that the product before and after the change is comparable.  Comparability is a central concept in the regulation of medicinal products; this tool provides an overview of the various parameters that might be required for a comparability exercise. 


Regulatory Tools (last update)


Regulatory Guidance (last update)

There are a number of specific guidelines covering the development of ATMP's, however, many more general biological/biotech guidance is also indirectly relevant since they provide the general principle described in ICH documents are harmonised across ICH member countries

Pharmacopoeial chapters with relevance to cell-based medicinal products:

Note: These figures do not include hyperlinks since the content requires subscription.


UPDATE: The Common Technical Document (CTD) (Version 2.1 December 2019)

Now with increased detail including excerpts from ICH guidelines and authors comments and suggestions
