Revisions to the general safety requirements for biological products--FD. Direct final rule.

The Food and Drug Administration (FDA) is amending the biologics regulations by adding "cellular therapy products" to the list of products excepted from the general safety test (GST) and by adding an administrative procedure for obtaining exemptions from the GST requirements for other biological products. FDA is taking this action because the GST may not be relevant or necessary for biological products, including cellular therapy products, currently in various stages of development. This direct final rule is part of FDA's continuing effort to achieve the objectives of the President's "Reinventing Government" initiative, and is intended to reduce the burden of unnecessary regulations on biological products without diminishing the protection of the public health. Elsewhere in this Federal Register, FDA is publishing a companion proposed rule under FDA's usual procedures for notice and comment to provide a procedural framework to finalize the rule in the event the agency receives any significant adverse comment and withdraws this direct final rule.
