If there’s one area of biologics where the FDA has been consistently busy lately it’s the perinatal cell therapy space.

The Association for the Advancement of Blood & Biotherapies or AABB recently had a very useful Q&A with the FDA on cord blood use. There are some important new things from the FDA on the marketing and use of cord blood in there. The agency was also quite blunt in some ways about the challenges, …

The FDA seems oddly slow in oversight of unproven stem cell clinic-related firms like one here in California called Invitrx Therapeutics. I’ve written before about Invitrx, but interactions between them and the FDA have continued including a new warning letter. It’s become a puzzling situation.
