3. CBER 3 How does FDA regulate cord blood for autologous use and use in first or second-degree relatives? Regulated solely under Section 361 of the Public Health Service Act, from which the HCT/P regulations derive (21 CFR 1271 Subparts A-F), unless more than minimally manipulated; for non-homologous use; or combined with another article with some exceptions such as preserving and sterilizing agents (§1271.10) –Establishment registration and listing rule –Donor eligibility and CGTP rules –Reporting and labeling requirements –Inspection, import, and enforcement provisions

4. CBER 4 How does FDA regulate cord blood from unrelated donors? Regulated as HCT/P under 21 CFR Part 1271 Subparts A-D (Registration, DE, and CGTP rules) Also regulated as a drug under the FD&C Act and as a biological product under Section 351 of the PHS Act, and therefore additional regulations apply –Labeling and advertising (21 CFR Part 201 and 202) –CGMPs (Part 211) –IND regulations (Part 312) –Licensing and general biological products standards (Parts 600, 601, 610)
