There’s a big FDA stem cell meeting coming along next week that has gotten much attention, but many people didn’t realize there’s also an FDA meeting on stem cells this week too in three days on September 8th.
I pasted this week’s meeting schedule at the bottom of this post from the FDA page. The meeting is a workshop entitled, “Public Workshop: Scientific Evidence in the Development of Human Cells, Tissues, and Cellular and Tissue-Based Products Subject to Premarket Approval”.
The meeting next week on September 12-13 getting all the attention is entitled, “Draft Agenda: Part 15 Hearing: Draft Guidances Relating to the Regulation of Human Cells, Tissues, or Cellular or Tissue-Based Products”.
Within the “Human Cells, Tissues, and Cellular and Tissue-Based Products” or HCT/P larger category the ones getting the most attention are stem cells. If you look at the speakers at this week’s meeting including the keynote by Irv Weissman, it’s pretty clear this meeting is focused squarely on stem cells even though it could apply to other products.
What’s the difference between the meetings?
The first meeting seems to be a broader look at the science related to stem cell products and considerations for their pre-market approval. The talks range from potential promise to serious negative outcomes that have been experienced, ethical and policy considerations, and then some other stuff that to me doesn’t quite seem to fit such as the warfare talk.
By contrast, the second meeting occurring next week is specifically focused on the four FDA draft guidances published last year and provides an opportunity for dozens of stakeholders to speak.
What will happen and be the aftermath of these meetings? One would need a stem cell crystal ball to be sure. Why is the FDA doing these meetings? Together they will demonstrate a reasonable effort on the part of the FDA to seriously tackle the stem cell issue on multiple levels, get various perspectives, and form a foundation for future decisions and potential regulatory actions. I’m hopeful the meetings will lead to a better oversight framework for stem cells that is more nimble, ultimately safer for patients, and better for the stem cell field overall.
