Institutional Biosafety Committee Member Training October 2014
Background Recombinant DNA work covered under NIH Office of Biotechnology Activities (NIH OBA) in: NIH GUIDELINES FOR RESEARCH INVOLVING RECOMBINANT OR SYNTHETIC NUCLEIC ACID MOLECULES (March 2013) Purpose of Guidelines: specify the practices for constructing and handling: (i) recombinant nucleic acid molecules, (ii) synthetic nucleic acid molecules, including those that are chemically or otherwise modified but can base pair with naturally occurring nucleic acid molecules, (iii) cells, organisms, and viruses containing such molecules.
IBC Institutional Biosafety Committee (IBC) Reviews all research that involves the use of rDNA NIH/OBA rDNA Guidelines as reference document Reviews research involving the use of infectious agents NOT rDNA Inclusive of subcommittees-needlestick and healthcare BMBL as a reference document
Biosafety Levels Biosafety levels are a combination of facilities, equipment and practices. Level 1: basic lab, good lab practices Level 2: limited lab access, specific training and practices Level 3: containment (biosafety cabinet), specific training and practices Level 4: full containment; specific facility, training and practices
Risk Assessment Factors Pathogenicity Route of Transmission Agent Stability Infectious Dose Concentration Availability of effective prophylaxis, treatment Availability of medical surveillance Host susceptibility
Risk Assessment Organism Hosts Vector Expression of foreign gene Protein produced Containment Facility Laboratory-specific protocol Training & expertise of personnel
History of the Guidelines The NIH Guidelines were implemented in response to public and scientific concern over the emerging science of rDNA technologies in the early 1970’s. By 1976, NIH had published the first set of guidelines which have been amended over time to allow for greater public access and a greater emphasis on safety.
Section I: Scope and Applicability If your institution receives NIH funding for rDNA research, then it must comply with the NIH Guidelines. Even if a project is privately sponsored, that research must still be conducted in accordance with the NIH Guidelines if conducted at an institution subject to the NIH Guidelines.
Section II: Safety Considerations Risk Assessment Risk Group 1 (RG1) agents are not associated with disease in healthy adult humans. Risk Group 2 (RG2) agents are associated with human disease which is rarely serious and for which preventive or therapeutic interventions are often available. Risk Group 3 (RG3) agents are associated with serious or lethal human disease for which preventive or therapeutic interventions may be available. Risk Group 4 (RG4) agents are likely to cause serious or lethal human disease for which preventive or therapeutic interventions are not usually available.
Section II: Safety Considerations Containment Containment should be a combination of standard microbiology practices, engineering controls, laboratory facilities and design. Containment is defined in: Appendices G, P, & Q of the NIH Guidelines Laboratory Safety Monograph (historical document) Biosafety in Microbiological and Biomedical Laboratories (BMBL)
Section III: Experiments covered by the NIH Guidelines III-A: transfer of drug resistance III-B: cloning of lethal toxins III-C: human gene transfer research III-D: infectious agents as vectors & transgenic animals III-E: generation of transgenic rodents III-F: exemptions
Experiments Covered by the NIH Level of ReviewSectionResearch Example IBC, RAC review and NIH Director review and approvalIII-ACipro resistant Bacillus anthracis IBC approval and NIH review for containment determinationIII-BCloning botulinum toxin expression into adenovirus IBC and IRB approval and NIH review before research particpant enrollmentIII-CHuman gene transfer IBC approval before initiationIII-D Expression of a nonnative protein in Staphylococcus aureus IBC notification at initiationIII-E Germline alteration of rodents which may be housed in BL-1 ExemptIII-FPurchased transgenic rodents
III-A: Major Actions Requires: IBC Approval, RAC Review, NIH Director Approval Before Initiation of Work Transfer of therapeutically useful drug resistance to organisms which may compromise human health/agriculture/medicine
III-B: Toxin Transfer Requires: NIH/OBA, IBC Review and Approval Before Initiation of Work Deliberate cloning of toxin molecules lethal to vertebrates at an LD 50 of less than 100 nanograms/Kg of body weight (e.g., botulinum toxin) Containment determined by NIH/OBA
III-C: (Deliberate Transfer of rDNA into Research Participants, ex. Gene Therapy) Requires: RAC Review, IBC and IRB Approval Before Participant Enrollment Human gene transfer (HGT) protocols All HGT trials except those covered under vaccine exemption require RAC registration. 20-30% will be publicly reviewed and may require public review prior to participant enrollment.
III-D: General Work Requires: IBC Review and Approval Prior to the Initiation of Work Involves RG 2-4 agents, host/vector system Cloned DNA from RG 2-4 agents into non-pathogenic prokaryotes RG 2-4 agents into whole animals, usually transgenic Recombinant plants Large scale experiments greater than 10L Generation of any transgenic animal other than BSL-1 rodents
III-E: Less Restrictive Work Requires: IBC Notification at the Initiation of Work (BSL-1 Containment), and Subsequent IBC Review and Approval rDNA molecules that contains less than 2/3 of any eukaryotic viral genome Transgenic rodents with BSL-1 containment (crossbreeding of transgenics now exempt at BSL-1) Whole plants that require minimal containment Anything else NOT covered under sections III-A through III- D & III-F
III-F: Exemptions Exempt from the NIH Guidelines and Does Not Require IBC Review or Approval rDNA molecules that are: Not in organisms or viruses Not a risk to health or the environment -See Appendix C Note: exceptions to exemptions!

Section IV: Roles and Responsibilities Responsibilities of the Institution: Ensure compliance with NIH Guidelines Establish IBC Appoint a Biosafety Officer if conducting BSL-3, BSL-4, or large-scale work Ensure IBC has expertise in the research that is reviewed Establish a medical surveillance program as needed Report all incidents to the NIH OBA
Section IV: Roles and Responsibilities Responsibilities of the IBC: Review rDNA research, and approve those research projects that are found to conform with the NIH Guidelines. This review shall include: -(i) independent assessment of the containment levels required by the NIH Guidelines for the proposed research; (ii) assessment of the facilities, procedures, practices, and training and expertise of personnel involved in rDNA research; (iii) ensuring that all aspects of Appendix M have been appropriately addressed by the PI; (vii) ensuring compliance with all surveillance, data reporting, and adverse event reporting requirements set forth in the NIH Guidelines. Notify the PI of the results of the IBC’s review and approval. Lower containment levels for certain experiments as specified in Section III-D-2-a, Experiments in which DNA from Risk Group 2, Risk Group 3, Risk Group 4, or Restricted Agents is Cloned into Nonpathogenic Prokaryotic or Lower Eukaryotic Host- Vector Systems.
