March 30, 2009AATB Spring Meeting, Orlando FL
To Discuss Today Regulatory basis - CGTP Scope of draft guidance Selected draft guidance recommendations and
examples. These are focused on responses to identified: Compliance issues Frequent questions Recovery issues Relevance to AATB members
Because of time constraints, only Subpart D related sections will be discussed today (not Subpart E: Reporting and Labeling)
Background: CGTP Regulation 21 CFR 1271 Subparts D and E
Proposed rule: January 8, 2001 Final rule: November 24, 2004
Addressed public comment Effective date: May 25, 2005 for HCT/Ps
recovered on or after this date Most of subpart D and all subpart E
requirements not currently effective for reproductive establishments
Subpart D: CGTP Requirements for methods, facilities, and
controls for manufacturing Manufacturers must recover, process, store,
label, package, and distribute HCT/Ps, and screen/test donors, in a way that prevents introduction, transmission, and spread of communicable diseases/agents Includes viruses, bacteria, fungi, parasites,
and TSE agents Broad goals applicable to wide range of HCT/Ps Establishments determine how to meet these
goals through their own procedures
CGTP Requirements Exemptions/alternatives Quality Program Personnel Procedures Facilities Environmental control Environmental monitoring Equipment Supplies and reagents Recovery Processing/process
controls
Process changes Process validation Labeling controls Storage Receipt, pre-distribution
shipment, and distribution
Records Tracking Complaint file Donor eligibility
determination
Core CGTP Requirements Are those requirements that directly relate to
preventing the introduction, transmission, or spread of communicable disease by HCT/Ps
Other CGTP requirements discussed in the guidance support the core CGTP requirements
You must follow all CGTP requirements applicable to the manufacturing steps you perform
If you determine that an applicable requirement is not appropriate for your operations, then documentation of justification is required
Donor eligibility requirements are considered core CGTP

Draft CGTP Guidance FDA recommendations for complying with 21 CFR part
1271, subparts D and E CGTP Reporting and Labeling.
Also addresses whether establishment registration and listing requirements apply in certain instances
FDA’s current thinking - for comment only Docket No. FDA-2008-D-0659 - comments due April 16,
2009 Federal Register Notice:
http://frwebgate.access.gpo.gov/cgi-bin/getdoc.cgi?dbname=2009_register&docid=fr16ja09-101
Guidance: http://www.fda.gov/cber/gdlns/tissuehctps.htm
Scope of Draft Guidance Applies to establishments that manufacture HCT/Ps
regulated: Solely under section 361 of the Public Health
Service (PHS) Act and 21 CFR part 1271 and As drugs, devices, and/or biological products
under Section 351 of the PHS Act and/or the Federal Food, Drug and Cosmetic Act
Applies to establishments that perform a manufacturing step under contract, agreement or other arrangement for another HCT/P establishment
Provides examples of how compliance can be addressed for CGTP, reporting and labeling requirements
Scope of Draft Guidance Includes many of the Q and A’s submitted by
professional associations (AATB and EBAA) to FDA in 2005 Many were modified in the FDA draft guidance Some of the AATB/EBAA Q and A’s might not be
consistent with FDA’s current thinking Consider comparing with AATB’s 2006 Guidance to
assess consistency with FDA’s current thinking Includes issues identified by the FDA Human Tissue
Task Force (established in 2006) evaluations and inspections of recovery establishments
Guidance recommendations are focused on preventing infectious disease contamination and cross contamination (including mix-ups) during manufacture
Selected Draft Guidance Recommendations and
Examples
CGTP Not Covered by CGMP/QS Regulation
Provides explanations of what CGTP requirements apply if the HCT/P is not a 361 HCT/P
These requirements would be in addition to the Drug current good manufacturing practice
(CGMP) requirements for HCT/Ps regulated as biological products or
Quality system (QS) regulation requirements for HCT/Ps regulated as medical devices.
If there is a conflict, the more specific regulation would supersede the more general one
CGTP Not Covered by CGMP/QS Regulation
All donor eligibility requirements (Subpart C) Prevention of the introduction, transmission, or
spread of communicable diseases (1271.145) Certain parts of manufacturing arrangements
(1271.150(c)(1)(ii) and (iii)) Procedures for sharing with other establishments
information pertaining to possible contamination or potential for transmission of communicable disease (1271.160(b)(2))
Audits (only biological products not covered) (1271.160(c))
CGTP Not Covered by CGMP/ QS Regulation
Prohibition on pooling (1271.220(b)) Predistribution shipment (1271.265(b)) HCT/P availability for distribution only after donor
eligibility established (1271.265(c)(2)) Packaging and shipping requirements
(1271.265(d)) Record keeping for 10 years (1271.270(d))
(facility cleaning and sanitation records for 3 years (1271.190(d)(2))
Certain records for contracts and agreements (1271.270(e))
Tracking (1271.290(a) – (g))
Examples Where No Corresponding CGMP or QS Regulation
HCT/Ps from 2 or more donors may not be placed in physical contact or mixed in a single receptacle during manufacture (pooling)
Where there is shipment within or between establishments before making the HCT/P available for distribution, you must: Establish criteria and document they are met
that are designed to prevent communicable disease transmission
Ship in quarantine
Manufacturing ArrangementsExamples of How to Ensure
Compliance with CGTP Requirements
Responsibilities are listed and understood Review test kit package inserts used by
contract test laboratory Review applicable procedures Review certifications where appropriate
(e.g., CLIA, Certificate of Analysis) Review previous compliance actions
1271.150(c)(iii)
Manufacturing Arrangements Recommendations Continued
Perform for cause and random comparisons of documentation provided by your contractor with source documents from the originator of the documents. (e.g., testing records)
Ensure the establishment has a quality program that addresses the operations they perform for you
Perform periodic audits that address review of compliance with all Part 1271 requirements applicable to the operations the establishment performs for you
Example of Manufacturing ArrangementProcessor receives HCT/Ps from a recovery establishment under contract and decides to audit the establishment for compliance with regulations for:Recovery, donor medical history interview, obtaining specimens for communicable disease testing, and shipping at appropriate temperaturesConsiders reviewing records provided by the recovery establishment to confirm accuracy of source such as
Attending physician Testing laboratory Coroner or hospital Next of kin
Considers accompanying a recovery team to review adherence to procedures and quality program activities
Quality Program and Sharing Information
Must ensure that procedures exist to share information (pertaining to possible contamination or transmission of a communicable disease) with other establishments known to have Recovered HCT/Ps from the same donor Performed manufacturing steps with the same
HCT/P Procedures must include provisions for assessing
risk and appropriate follow-up, and notification of all entities involved as necessary
Recommend that procedures are defined in your contracts, agreements and other arrangements
1271.160(b)(2)
Example of Information Sharing:Positive Test Results Received
Tissue establishment evaluates test results and determines if there are concerns for potential increase in risk of transmission of a relevant communicable disease agent or disease by the HCT/P (even if the test is not recommended by FDA)
Shares results with the establishment that recovered the HCT/Ps from the donor
Recovery establishment shares results with other establishments that received HCT/Ps from the same donor
Tissue establishments should notify consignees of released HCT/Ps
Example of Information Sharing: Adverse Reaction
Recovery establishment recovers HCT/Ps for several processing establishments
Recovery establishment receives information from one processor that a recipient had developed a serious infection
Recovery establishment is responsible for sharing this information with other processing establishments that received HCT/Ps from the same donor
Computer SoftwareValidation or Verification
Applicable if computer software is used to comply with any core CGTP requirement
Validation examples: If you develop your own software to store
information used to make donor eligibility determinations
If you use a computer generated labeling system developed for a different intended use (labeling blood products)
Verification example: If you use a commercial spread sheet to record donor testing results used to make a donor eligibility determination
1271.160(d)
Availability of Procedures
Must be readily available to personnel in the area where operations are performed
Do not have to be physically maintained in the area of operation if impractical
Examples Copies of applicable procedures on paper or
electronically accessible should be taken to a recovery site
If not feasible to physically keep in the processing clean rooms, then can be in an adjacent area
1271.180(c)
Facility Requirements: Examples Applicable to Recovery
The area used for recovery should be evaluated for: Suitable size, location and construction for aseptic
procedure Limited access Good state of repair Adequate lighting, ventilation and airflow Access to running water and sink Working surfaces – verified cleaning agents used
and use documented Recommend development of a checklist to
document that the location meets established parameters each time a recovery is performed
1271.190(a)
Facilities: Separate Areas Needed? Evaluate the type of area that a task would require
in order to prevent contamination or cross-contamination
Recommendation that it is not appropriate to utilize a clean-room used for processing for: Preparing packaged, recently recovered HCT/Ps
for shipment to another facility Prepackaging freshly recovered HCT/Ps for
quarantine Handling blood specimens to be used for
infectious disease testing Decontaminating instruments used for recovery
or processing
1271.190(c)
Environmental Controls Related to Recovery
Procedures must be established and maintained to prevent contamination or cross-contamination
Environmental controls should be in place at each recovery site
Establish recovery site suitability parameters and verify that they have been met
Operating room setting is recommended but not required
If other types of facilities are used for recovery then they must provide adequate temperature and humidity controls and ventilation
1271.195(a)
Equipment RecordsDocument and Maintain
Records for use of each piece of equipment including identification of each HCT/P manufactured with it
Cleaning and maintenance records of equipment including those instruments that are regularly washed and disinfected
For recovery instruments cleaned and sterilized by a contract facility:
Obtain and approve procedures and review records Establish and maintain verification procedures for
sterilization specifications Contract facility does not have to register as this is not
a manufacturing step
1271.200(e)
Equipment for Recovery Recommendations
No requirement to segregate equipment used for different donors prior to cleaning
Acceptable to place multiple instrument trays into automated washers
Recommend if possible, that instruments used on the same type of tissue be cleaned together
Should ensure that automated washers operate consistently and are cleaned/maintained according to established procedures
Containers and solutions used in instrument cleaning can be reused per manufacturer’s instructions
Supplies and ReagentsVerification of Specifications
Ensure that a verification system is in place to meet specifications by the: Establishment that uses the supply or reagent or Vendor
Verification examples for recovery supplies: Designed to prevent leakage that could cause
contamination or cross-contamination if used to wrap, package or store HCT/Ps
Shipping containers used to transport HCT/Ps are capable of maintaining expected storage environment relative to controlling contamination
1271.210(a)
RecoveryProcedures and Records
Recovery is a core CGTP, therefore procedures and records must be established and maintained for:FacilitiesEnvironmental controlEquipmentSupplies and reagentsLabeling controlsStorage and Receipt, predistribution shipment and distribution
1271.215
Recovery: Examples for Reducing Contamination/Cross Contamination Evaluate technical procedures used such as
Aseptic technique Use of published industry practices Specific body cooling parameters established
Evaluate personnel involved for Experience, education and training
Evaluate equipment, supplies, and reagents used for
Appropriate design Records and procedures for maintenance, cleaning,
sanitizing, calibration and other activities Establish and document suitability of facilities
where recovery takes place (including audits)
Recovery: Examples for Verifying and Documenting Donor Identification
Critical for HCT/P tracking Prior to recovery of HCT/Ps from a deceased
donor, compare the donor’s identification with Information on the consent/authorization
documents Relevant medical records Other identifiers such as age, sex, race and
weight Document the methods used to verify donor
identity and the source of information Processor could periodically audit recovery
establishment records to compare them with other available information related to the donor
Processing: Recommendations for Pre-Processing Cultures
Issues to take into consideration when you evaluate pre-processing culture results to determine whether to utilize a donor:Capability of your microbiological testing, disinfection, and sterilization processes (validated to sterility assurance level of 10-6) Identify rule out organisms (Clostridium, or Group A Streptococcus) that are difficult to eliminateIdentification of multiple cultures for enteric or pathogenic microorganisms
Records: Methods for Retention Maintain electronically, original paper records or
as true copies such as photocopies, microfiche, or microfilm
Back-up is required if stored electronically Examples of retention requirements:
Paper records are scanned into a computer file that is backed up. These are true copies so the paper records may be destroyed
Paper records are re-typed into a computer file. It is not possible to determine that these are true copies, so the original paper records must be kept
1271.270(c)
