The manufacturers of regenerative medicines make changes during the development and after approval, for the purposes of improving the process, scale-up, site-changes, and so on. As an approach to explain comparability, some cases are appropriate to follow the biotechnological products, while some cases are not, then the extent of requirement to demonstrate comparability is an issue. In this session, we will have speakers who will share their insights and experiences. The panel discussion will follow to figure out the general considerations and approaches to the current issues.
