  1. “361” Human Cells, Tissues, and Cellular and Tissue-Based Products (HCT/Ps) Samuel B. Barone, MD Division of Human Tissues

  2. Overview • What are HCT/Ps? • History of Tissue Regulation • “361” HCT/Ps • Tissue Rules/21 CFR 1271 • Registration • Donor Eligibility • Current Good Tissue Practice

  3. What are HCT/Ps? • Regulatory definition: Articles containing or consisting of human cells or tissues that are intended for implantation, transplantation, infusion, or transfer into a human recipient • Encompass a wide variety of products 21 CFR 1271.3(d)

  4. From deceased (cadaveric) donors: Musculoskeletal tissues Skin Dura mater Cardiovascular tissues Ocular tissues Tissue/device and other combined products From living donors: Hematopoietic stem/progenitor cells from peripheral and cord blood Other cell therapy products (e.g. pancreatic islets, mesenchymal stem/stromal cells, fibroblasts) Reproductive cells and tissues Examples of HCT/Ps 21 CFR 1271.3(d)

  5. Not HCT/Ps • Vascularized organs • Minimally manipulated bone marrow • Tissues intended for educational or non-clinical research use (not intended for transplantation) • Xenografts • Blood products • Secreted or extracted products; e.g., human milk, collagen, cell factors • Ancillary products used in manufacture • In vitro diagnostic products • Blood vessels recovered with an organ 21 CFR 1271.3(d)

  6. HISTORY OF TISSUE REGULATION

  7. History of HCT/P Regulation • 1993: interim final rule for immediate implementation in response to infectious disease concerns with imported tissues • 1997: final rule • Musculoskeletal, skin and ocular only (deceased donors) • Legal authority: Section 361 of the Public Health Service (PHS) Act – prevent the introduction, transmission, or spread of communicable diseases

  8. Proposed Approach • 1997: FDA announced a proposed approach to all human cells, tissues, or cellular or tissue-based products (HCT/Ps) • Tiered, risk-based approach • Broader scope, included previously unregulated cells and tissues • Issued through rulemaking in 3 parts • Entire 21 CFR Part 1271 became effective on May 25, 2005

  9. Goals • HCT/Ps carry a potential risk of communicable disease transmission from the donor to the recipient • Prevent the introduction, transmission, and spread of communicable diseases by HCT/Ps

  10. 21 CFR Part 1271 Applicability • For some HCT/Ps (“361” HCT/Ps) it is the sole regulatory requirement • Authority from section 361 of the PHS Act • Prevent the introduction, transmission, or spread of communicable disease • No pre-market review

  11. “361” HCT/Ps • Minimal manipulation • Advertised/labeled for homologous use only • Not combined with another article • Does not have a systemic effect (except for autologous, family-related or reproductive use) 21 CFR 1271.10(a)

  12. Other Cells and Tissues • If the cells or tissues do not meet the requirements to be regulated solely under 361 of the PHS act, are also regulated as drugs, devices, and/or biological products • pre-market approval required • demonstrate safety and efficacy • For these HCT/Ps, Part 1271 applies, but supplements other existing requirements

  13. Tissue Reference Group • Provides a single reference point for product specific questions concerning jurisdiction and applicable regulation of HCT/Ps http://www.fda.gov/BiologicsBloodVaccines/TissueTissueProducts/RegulationofTissues/ucm152857.htm  

  14. 21 Code of Federal Regulations Part 1271

  15. 21 CFR Part 1271

  16. Registration and Listing

  17. General Provisions • Purpose; Scope • Definitions • Criteria for regulation solely under section 361 of PHS Act • Exceptions from the requirements

  18. Definition: Manufacture • Manufacture means any or all steps in the recovery, processing, storage, labeling, or distribution of any human cell or tissue, and the screening or testing of the cell or tissue donor 21 CFR 1271.3(e)

  19. Registration and Listing • Any establishment that manufactures HCT/Ps must • Register and submit a list of every HCT/P it manufactures within 5 days after beginning operation • Re-register annually • Update if change in location or ownership • All foreign establishments importing HCT/Ps to the US must register and list each HCT/P 21 CFR 1271.21, 1271.10(b)

  20. Registration and Listing cont. • Establishment registration is not a pre-market review program • An establishment may begin to market its product once it registers (361 HCT/Ps) • There are periodic inspections, but distribution may begin before the establishment is inspected 21 CFR 1271.21, 1271.37

  21. DONOR ELIGIBILITY

  22. Donor Eligibility • A donor-eligibility determination, based on donor screening and testing for relevant communicable disease agents and diseases (RCDADs), is required for all donors of HCT/Ps, with some exceptions • HCT/P must not be administered until the donor has been determined to be eligible, with some exceptions 21 CFR 1271.45(b,c)

  23. Donor Screening and Testing • Screening for risk factors and clinical evidence of disease • Current donor medical history interview • Current physical assessment/examination • Medical records; coroner and autopsy reports, if available • Testing • FDA-licensed, cleared, or approved tests • CLIA-certified laboratory (very few outside the US) 21 CFR 1271.65/.80

  24. Requirements 21 CFR 1271.3(r)/.75/.85

  25. Donor Screening and Testing • FDA Guidance for Industry: Eligibility Determination for Donors (8/27/07) • Provides FDA’s current thinking • Assists manufacturers in complying with the requirements http://www.fda.gov/BiologicsBloodVaccines/GuidanceComplianceRegulatoryInformation/Guidances/Tissue/ucm073964.htm

  26. CURRENT GOOD TISSUE PRACTICE

  27. Subpart D – Current Good Tissue Practice • Methods, facilities, and controls for manufacturing to prevent communicable disease transmission • Broad goals applicable to the wide range of HCT/Ps • Establishments have the flexibility to determine how to meet goals through SOPs • Narrower in scope than GMP • Requires a quality program to prevent, detect, and correct deficiencies that could increase communicable disease risk 21 CFR 1271.150

  28. Donor eligibility determinations Exemptions and Alternatives Quality Program Personnel Procedures Facilities Environmental Control and Monitoring Equipment Supplies and Reagents Recovery Processing and Process Controls Process Changes Process Validation Labeling Controls Storage Receipt, Pre-distribution Shipment, and Distribution Records Tracking Complaint File Requirements 21 CFR 1271.150-320

  29. Procedures • Establish and maintain procedures for all steps that are performed during manufacture of the HCT/P • Designed to prevent circumstances that increase the risk of introduction, transmission, or spread of communicable disease • Reviewed, approved and followed • Available to personnel • Can adopt standard procedures from another organization 21 CFR 1271.180

  30. Adverse Reaction Reporting • Adverse reaction: A noxious and unintended response to any HCT/P for which there is a reasonable possibility that the HCT/P caused the response • Investigate any adverse reaction involving a communicable disease from an HCT/P that the establishment made available for distribution • Report those that are fatal, life-threatening, result in permanent impairment or permanent damage, or necessitate medical or surgical intervention 21 CFR 1271.350(a)

  31. HCT/P Deviation Reporting • HCT/P deviation: A deviation from applicable regulations, standards, or established specifications, or an unexpected event that relates/may relate to communicable disease transmission or HCT/P contamination • Investigate all deviations related to a distributed HCT/P • That occurred in your facility or • A facility under contract, agreement, or other arrangement to you • Report certain deviations 21 CFR 1271.350(b)

  32. Inspection and Enforcement • Inspections • Usually unannounced • Frequency is at the Agency’s discretion • Inspections include foreign establishments • Donor confidentiality observed • Orders of retention, recall, destruction, and cessation of manufacturing • Address actions FDA can take if manufacture of HCT/Ps is in violation of the regulations 21 CFR 1271.400
