That @U.S. FDA is recognizing here the urgent need for regulatory strategies to evolve to match the pace of scientific advances in ways that streamline bringing the science safely to patients is incredibly important. I hope these new policies provide a foundation that will eventually allow certain kinds of genetic surgeries to become as routine as life-saving conventional surgeries, in which the process is robust and standardized enough to be rapidly adapted to each patient, without the need for a separate multi-year regulatory process for each surgery.

"Nearly 30 years after the sequencing of the human genome, bespoke therapies are close to reality. The FDA will work as a partner and guide in ushering these therapies to market, and our regulatory strategies will evolve to match the pace of scientific advances."
