The purpose of this workshop is to discuss the current state of the science for development and testing of certain cellular therapies and tissue-based products. In particular, FDA is convening this public workshop with relevant stakeholders to discuss best practices on generating scientific data necessary to further facilitate the development of cellular therapies, including stem cell products. Within 6 months after the meeting, FDA will issue a transcript of the meeting. This workshop will fulfill the requirement under the Food and Drug Omnibus Reform Act of 2022, section 3205.

## II. Topics for Discussion at the Public Workshop

The workshop will include presentations and panel discussions with experts from research and academic institutions to identify and discuss scientific considerations, opportunities, and challenges to help inform the development of cellular therapies and tissue-based products. Topics discussed during the workshop include:

1. The current state of the science for tissue and cell-derived therapies and explore what challenges remain as the field continues to mature.

2. Nonclinical work to assess the safety of cell therapy products in support of product development.

3. Considerations for characterization of cell therapy products to help ensure manufacturing quality during product development and through commercialization.

4. Clinical considerations and future directions for locally-administered cell therapies under investigation for niche indications
