Human cells, tissues, and cellular and tissue-based products; establishment registration and listing. Interim final
Abstract:
The Food and Drug Administration (FDA) is issuing an interim final rule to except human dura mater and human heart valve allografts, currently subject to application or notification requirements under the Federal Food, Drug, and Cosmetic Act (the act), from the scope of the definition of "human cells, tissues, or cellular or tissue-based products (HCT/P's)" subject to the registration and listing requirements contained in 21 CFR part 1271. That definition became effective on January 21, 2004. FDA is taking this action to assure that these products, which are currently subject to the act and therefore regulated under the current good manufacturing practice regulations set out in the quality system regulations in 21 CFR part 820 are not released from the scope of those regulations before a more comprehensive regulatory framework applicable to HCT/P's, including donor suitability requirements, good tissue practice regulations, and appropriate enforcement provisions, is fully in place. When that comprehensive framework is in place, FDA intends that human dura mater and human heart valves will be subject to it. FDA intends to revoke this interim final rule at that time.
