BEIJING — A powerful new national medical ethics committee, which will approve all clinical trials involving high-risk biomedical technologies, is at the center of a regulatory shakeup Chinese authorities are planning in the aftermath of the widely condemned “CRISPR babies” experiment, STAT has learned.

The technologies that will be regulated by the ethics committee are often new and are deemed risky either because of safety or moral concerns. They will include not only gene editing, but also cloning, cell therapy, xenotransplantation, mitochondrial replacement, and nanotechnology.
