Application Process The application was formally received on 1 April 1999. The application was stalled on 16 April 1999 whilst additional information was sought from the applicant. The application was verified on 31 March 2000. The application was not publicly notified. The documents available for the evaluation and review of the application by ERMA New Zealand included; the application, appendices (including copies of all literature cited), general reference material on retroviruses, material from other jurisdictions including the Genetic Manipulation Advisory Committee (GMAC) Guidelines for Small Scale Genetic Manipulation Work April 1995 (Australia), and comments from the Department of Conservation (DoC). The application was determined by the Genetically Modified Organisms Standing Committee of the Authority appointed in accordance with section 19(2)(b) of the Hazardous Substances and New Organisms (HSNO) Act 1996. The Committee comprised members of the Authority: Professor Barry Scott (Chair), Helen Hughes, and Dr Oliver Sutherland. Environmental Risk Management Authority Decision: Application GMD99002 Page 2 of 18 Additional Information In the course of its consideration the Committee agreed that further information was required on aspects of the application. Information was requested primarily with respect to the occupational risk to personnel working with these organisms, and specifically on the adequacy of the proposed containment controls to minimise this risk. It was agreed that an expert virologist review and comment on the following aspects of the application: the adequacy of the proposed controls to manage the risks associated with the organisms, principally the occupational risk to workers any additional risks associated with the applications not identified in the ERMA New Zealand Evaluation and Review, and any additional measures required to manage those risks In addition, advice was sought on the appropriateness and feasibility of requiring the applicant to test for the production of replication-competent retroviruses in cells and in the packaging cell lines to be utilised in the development of genetically modified retroviruses. Information received from the external reviewer on the adequacy of the proposed controls was considered by the Committee. No additional risks were identified by the reviewer that had not been identified in the ERMA New Zealand Evaluation and Review Report. Relevant Legislative Criteria The application was lodged pursuant to section 40(1)(b) of the HSNO Act 1996. The matters considered in making this decision comprise those set out in sections 37, 44 and 45 of the Hazardous Substances and New Organisms Act 1996, and those relevant matters in Part II of the Act. Consideration of the application followed the relevant provisions of the Hazardous Substances and New Organisms (Methodology) Order 1998. The Application Scope of the application The application seeks approval for a multi-stage programme; including the development of genetically modified E. coli, retroviruses, and the development of the genetically modified cell lines. The development of specified categories of genetically modified organisms, as defined in Category A and B of the Hazardous Substances and New Organisms (Low-Risk Genetic Modification) Regulations 1998 are able to be considered by an Institutional Biological Safety Committee (IBSC) under delegated authority from the Environmental Risk Management Authority (the Authority). However Category C experiments as defined in the regulations cannot be considered under delegated authority. Environmental Risk Management Authority Decision: Application GMD99002 Page 3 of 18 The development of the genetically modified retroviruses as a part of this application is required to be considered by the Authority, as the manipulation techniques and materials to be utilised make the development fall within the definition of a Category C (c) experiment. A number of the other stages of the programme, including the development of genetically modified E. coli, are not Category C experiments and could have been considered by an IBSC, however they have been included in this application in order that the programme as a whole be considered as. Identification of the organisms In the case of this application not all of the genetic modifications are fully described by the applicant. The range of foreign genes to be introduced into the organisms has not been completely specified, as this can only be determined as the research proceeds. However, the applicant has identified the general sources of the genes that will be used, ie papillomaviruses, adenoviruses and eukaryotes (primarily mammals). In addition, the applicant has identified that they are concerned with genes that will assist them to study the role of viral and cellular proteins in cell cycle control. The Authority accepts that in the case of the development of genetically modified organisms an exact identification of all of the elements of the organisms may not be able to be specified at the outset of the research. However this approval (in the description of the organisms approved on page 1) details the organisms that may be developed and the range of the genetic modifications that can be introduced. This position is consistent with policies developed by the Authority for the identification of organisms. The ERMA New Zealand Protocol Interpretations and explanations of key concepts (Number 3, Series 2) provides for this type of identification specifying that… if a complete taxonomic description is difficult or problematic the Authority will, within the latitude provided by the requirements of the HSNO Act, require a description of the biological properties of the organism. In general, it will require relatively more detailed information where the potential risks are high and relatively less detailed information where the potential risks are low. Adequacy of the Proposed Containment Regime In considering the adequacy of the proposed containment regime the Committee considered, inter alia: i. the ability of genetically modified organisms (including Escherichia coli strains K12 and B, genetically modified replication-defective but infection-competent retroviral vectors, and, cell lines) to escape from containment, including inter alia: (a) the risk of inadvertent infection of personnel working with the organisms (b) the adequacy of PC1 and PC2 containment levels for containing organisms under this approval ii. the ability of the organisms to establish self-sustaining populations iii. the ease of eradication of any populations established. Environmental Risk Management Authority Decision: Application GMD99002 Page 4 of 18 Ability of genetically modified organisms to escape from containment, establishment of self-sustaining populations and ease of eradication In accordance with section 44(b) the Committee considered the ability of genetically modified organisms as a part of this application to escape from containment. The principal mechanisms of escape considered by the Committee included: i. inadvertent release, via human error or failure of procedures ii. deliberate action (sabotage) iii. natural disaster iv. infection of personnel working with the organisms. And furthermore, having escaped that the organisms would fail to be recovered as a result of: deficiencies in procedures, including identification of material inadequacy of contingency plans infection of personnel. The organisms are required to be contained in an approved containment facility (under the Biosecurity Act 1993) in compliance with the Ministry of Agriculture and Forestry (MAF) Biosecurity Authority (Animal Health and Welfare) Standard 154.03.02: Containment Facilities for Microorganisms. This standard is employed to meet the requirements of the Hazardous Substances and New Organisms (HSNO) Act 1996. In addition the operation, construction and management of the facility must be in accordance with the relevant provisions of the Australian/New Zealand Standard (AS/NZS) 2243.3:1995 Safety in Laboratories Part 3: Microbiology at Physical Containment Level 1 or 2. Furthermore, the applicant must comply with the additional controls imposed by the Authority in this decision. The principal pathway for escape of the organisms from containment, other than infection of workers, would be inadvertent, or deliberate removal of the organisms from the facility. A condition of facility registration is that the approval holder (facility Operator) must prepare, maintain and implement a quality assurance programme and procedures that address the requirements of the standard, including the operating requirements. The manual and operating procedures approved by the facility Supervisor2, are required to address the containment requirements (including how controls imposed by the Authority are to be met), training requirements for personnel working within the facility, and internal quality systems in place. In addition, to ensure that personnel working with these organisms are aware of, and understand all of the requirements of containment, including the provisions of the MAF Biosecurity Authority/ERMA New Zealand Standard, AS/NZS2243.3: 1995, and the additional controls imposed in this decision, the applicant is required to prepare a laboratory operations manual (containment manual) for all persons working with organisms under this approval. This containment manual is required to be available at all times, and all personnel are required to sign 2 An inspector appointed under the Biosecurity Act. Environmental Risk Management Authority Decision: Application GMD99002 Page 5 of 18 a declaration stating that they have read and understood the relevant standards, and the additional controls specified in this approval. Taking into account that the applicant has experience in developing and using these organisms in containment for research purposes, and additional controls imposed to ensure that all personnel are adequately trained in the containment requirements, the Committee was satisfied that the likelihood of an escape of these organisms from containment by inadvertent removal is very low. The Committee was satisfied that the containment regime in place would equally minimise the likelihood of deliberate action (sabotage) or natural disaster leading to a breach in containment. Inadvertent Infection of Personnel Working with the Organisms The Committee considered that the principal risk associated with this application is the risk that personnel working with these organisms could become inadvertently infected with the retroviral vectors they are handling. Such an infection route would also constitute a pathway for the escape of the organism from containment. The vectors included in this application are replication-defective (in that they lack essential gene products that would enable them to propagate) and therefore are only able to infect cells they directly come in contact with and not be able to produce more infective particles. However replication-competent retrovirus could be formed if recombination occurs between the retroviral vector and an (undetected) integrated retrovirus in the cell(s) used. This recombination event could restore the deleted genes into the vector and make it a fully functional retrovirus. The applicant has indicated that it is not possible to guarantee that the cell(s) and cell lines to be used will be retrovirus-free, so that there exists a prospect of replication-competent viruses being formed. However the probability of this occurring is considered to be low. Retroviral vectors have been used since the early 1980s and published reports of reconstitution of replication competence are uncommon. No evidence is available that the cell lines to be used (HeLa and A549) contain any endogenous retroviruses, and there is no evidence that any replication-competent retroviral vectors have been generated in either of these cell lines. These cell lines have been used for many years by many researchers for a variety of retroviral infection (and other) experiments so there is reasonable certainty that they are safe for use. Furthermore, considerable research involving retroviral vectors is undertaken internationally and no major incidents, including infection of workers, have been identified in the scientific literature available. In the unlikely event of the generation of a replication-competent retrovirus, and in the event of that organism escaping from containment, it would be unlikely that the organism would be able to be recovered or eradicated, and there is a remote possibility that it could spread if the infection path could not be controlled. However, the Committee were satisfied that the likelihood of the generation of a replicationcompetent retrovirus is very low. The Committee noted the comments of the expert reviewer that although it was uncommon for a recombination event between a recombinant replication-deficient retrovirus and an endogenous Environmental Risk Management Authority Decision: Application GMD99002 Page 6 of 18 retrovirus in a packaging system to occur, that personnel working with these organisms should be adopting containment measures on the assumption that the stocks and cells do potentially contain replication-competent retroviruses. All experiments involving work with retroviruses will be conducted under PC2 containment conditions, as specified in the AS/NZS 2243.3: 1995. The application states that the experiments will also be undertaken in accordance with the Australian Genetic Manipulation Advisory Committee Guidance for work involving genetically modified viruses for gene transfer into animal and human cells (Appendix 5 of the Guidelines for small scale genetic manipulation work). This document provides guidelines based on good virological and tissue culture techniques. The Committee has reviewed the guidelines and incorporated a number of the elements into the controls to which this approval is subject. These additional control measures over and above the requirements of PC2 containment are designed to further minimise the possibility of infection of personnel working with retroviruses, and include: the use of a biological safety cabinet of class II (refer AS 2252.2 3) for all experiments involving the handling of retroviruses handling of dishes and plates of cells containing human-infectious viruses in larger plates (or inverted lids) to provide traps for accidental spills storage of tissue cultures infected with human-infectious or potentially human-infectious viruses in incubators dedicated to the use of human-infectious viruses storage of human-infectious viruses or infected cell lines in a section of the freezer specifically designated for this purpose and clearly marked to this effect Furthermore, additional controls have been imposed in this approval requiring the facility Operator in conjunction with the IBSC, to ensure that only suitably qualified trained personnel may handle human-infectious recombinant viruses, and that their qualifications and training records be available for inspection. Taking into account the additional controls imposed in this decision derived in part from the GMAC Guidelines, and the specific requirements with respect to the training and qualifications of personnel working with genetically modified retroviruses, the Committee considered that probability of a worker being infected is low. The key factor in enabling this risk to be managed to a low level, however, is the management and oversight by those responsible for ensuring the controls imposed in this decision are rigorously adhered to. Adequacy of PC1 and PC2 containment levels for containing genetically modified organisms under this approval As noted above this application covers the development of a range of genetically modified organisms, including E. coli, retroviruses, and cell lines that each present differing risk profiles. 3 AS 2252.2 Part 2: Laminar flow biological safety cabinets (Class II) for personnel and product protection Environmental Risk Management Authority Decision: Application GMD99002 Page 7 of 18 E. coli The low-risk regulations referred to above, the Hazardous Substances and New Organisms (Low-Risk Genetic Modification) Regulations 1998, specify the appropriate level of containment for the development of genetically modified organisms in accordance with the manipulation techniques and materials utilised. Theses regulations state that where certain techniques are performed (defined as Category A or B) using host/vector systems listed in Schedule 2 of the regulation the appropriate level of containment is Physical Containment Level 1 (PC1) as defined in the in 2243.3:1995. Schedule 2 of the HSNO Low-Risk Regulations (referred to above), Approved Host/Vector Systems, identifies as an approved host E. coli K12 or E. coli B derivatives that do not contain conjugative plasmids4 or generalised transducing phages5. Approved vectors for use with these E. coli strains are either non-conjugative plasmids or specific bacteriophage6. The particular nucleic acids used in each modification will determine whether Category A or B applies, however PC1 is the required containment for both, where approved host/vector systems are used. Controls to which this approval is subject therefore require that the development of genetically modified E. coli be undertaken at Physical Containment Level 1 (PC1) as defined in the Australian/New Zealand Standard 2243.3:1995. Retroviruses The development of the retroviruses, and infection of the cells lines constitute Category C experiments and are required to be undertaken at Physical Containment Level 2 (PC2) as defined in AS/NZS 2243.3:1995. In addition, as a result of the risk of infection of personnel working with these organisms the Committee has imposed a range of additional controls to address particular issues of training and the qualifications personnel working with these organisms, and other measures to minimise the prospect of inadvertent infection occurring. The Committee was satisfied that adherence with the requirements of the relevant standards including the MAF Biosecurity Authority/ERMA New Zealand containment standard, the relevant sections of AS/NZS 2243.3: 1995, and the additional controls specified, can adequately contain organisms specified under this approval, and in particular, will minimise the prospect of an escape from containment via infection of personnel. Population establishment and ease of eradication The majority of the organisms covered under this approval are not in themselves able to enter the natural environment and all microorganisms covered under this approval are required to be maintained in specialised vessels (petri dishes or tubes) within the containment facility, containing specific culture media required for the survival of the organism. Retroviruses covered under this approval cannot survive independently outside of a host cell. Conjugative plasmid: a plasmid containing a set of transfer genes that promotes bacterial conjugation (transfer of DNA from one bacteria to another). 4 5 Transducing phages: virus particle containing host cell DNA instead of the viruses’ own genes. 6 Bacteriophage: a virus which infects bacteria and is usually species-specific. Environmental Risk Management Authority Decision: Application GMD99002 Page 8 of 18 E. coli The ability of E. coli to establish a self-sustaining population was considered in the context of application NOC99007 (to import into containment genetically modified E. coli), approved by the Authority in March 2000. In the decision on that application it was noted that E. coli strain K12 has been subcultured in research laboratories since 1922 and the closely related strain B has been subcultured for over 30 years. They are not known to colonise the alimentary tract of a human host or cause any symptoms of disease. The strains are genetically crippled and therefore cannot survive without certain growth factors. As the laboratory-based strains of E. coli will be maintained in approved containment, are unable to survive outside of controlled conditions, and do not contain self-transmissible vectors, the Committee in that case considered that escape and establishment of self-sustaining populations, which might cause adverse effects, was extremely unlikely. Retroviruses Replication-deficient retroviruses would be unable to establish a self-sustaining population, as they are unable to propagate themselves. For a replication-deficient retrovirus to establish a self-sustaining population it would first be required to recover its original gene complement, and therefore become ‘replication-competent’. Retroviruses have very small genomes (only 7-10 kilobases) so that carrying additional foreign genes will confer a packaging disadvantage on the virus and, consequently, is likely to make it less infective. An escaped and infective retrovirus is unlikely to carry foreign genes and so any infected individuals will be at risk primarily from the symptoms caused by that virus. Any affected individuals may be able to be identified and treated to ameliorate the effects, as well as controlling the retroviruses spread. Retroviruses are transmitted primarily by direct contact between infected body fluids and other suitable cells, so that spread of the virus would be able to be managed. Cell Lines The ability of cell lines containing foreign DNA to establish a self-sustaining population was considered in the context of application NOC99004 (to import into containment genetically modified mink epithelial cell line modified by human and firefly DNA), approved by the Authority in October 1999. In the decision on that application it was noted that the cell line could not survive unassisted in the uncontrolled environment. The Committee took into account that the cells could only survive (i) in a laboratory cell culture system that provides a complex and accurately balanced mixture of highly purified nutrients and a stable temperature, or (ii) after being placed by surgery or injection inside an immune system-weakened laboratory animal. Furthermore, the Committee noted that there has been no recorded instance of a cultured cell acquiring an ability to naturally infect an animal or plant. It was, however, noted that in the case of NOC99004 no viral or other infectious agent was used in the genetic transformation of the cell line. The issue of infection of workers from viral components is addressed in the present decision. Environmental Risk Management Authority Decision: Application GMD99002 Page 9 of 18 Effects of the Organism As a result of the low likelihood of organisms under this approval surviving or persisting in the environment, and the low likelihood of the escape of organisms from containment, the principal effect considered by the Committee was the effect on personnel working with genetically modified retroviruses in the event of infection. Occupational risk to workers This approval covers the use of several different retroviral vectors, some of which are capable of infecting only a specific host (such as mouse), while others have the potential to affect several species, including humans. As the retroviral vectors used in this application are replication-defective, any escape is expected to result only in the infection of cells that the virus comes in direct contact with. However, as noted previously, there is a possibility for a replication-competent virus to be created, but it too requires direct contact with uninfected cells to escape. Infection of a researcher, or other person, with one of the retroviral vectors (whether or not the vector is replication-competent) could have one or more of the following effects: i. alteration of cellular processes as a consequence of retroviral infection ii. expression of the foreign gene in the recipient iii. random insertion of the virus into the genome could induce a mutational change (such as knocking out a gene) in an endogenous gene if the insertion occurred within it iv. random insertion of the retrovirus could induce cellular transformation (ie tumour formation) rather than a simple mutational change. The most significant of these effects is the possibility of expression of the genes that the vector contains. The consequences will be larger for a replication-competent vector since this would be able to spread to other cells. Most of the foreign genes to be utilised in these experiments are those involved in cell cycle control, and therefore there is a high likelihood that infected cells would have altered growth and/or development. The extent to which growth and development of cells would be altered can not be precisely defined at this point, although considering the nature of the genes involved, some of the effects on the infected cells may be significant. The nature of the effects would also be dependent upon the types of cells infected, for example whether they are short-lived epithelial cells or pluripotent stem cells. Retroviruses are only able to infect cells that have the appropriate cell surface proteins, so that not all cells will have the same susceptibility to infection. If the vector is unable to replicate effectively the effect may be limited to the infected cells or tissues. The effects of such an infection could range from: i. non-demonstrable effects, due to the foreign genes having very little effect on the infected cell(s) ii. local effects on the growth or development of the infected cell(s) or tissue that may be treatable Environmental Risk Management Authority Decision: Application GMD99002 Page 10 of 18 iii. more severe effects such as tumour development or organ function disruption. However, oncogenesis is considered to be of lower likelihood relative to the other effects because it often requires separate mutations in two or more genes. The likelihood of the occurrence of other effects listed aboved is considered to be very much lower as a result of: The fact that only about approximately 10% of the human genome appears to code for specific genes, and therefore there is a high probability that a retrovirus will insert at a location that will not disrupt genome function. The fact that the effects of other viruses that commonly infect humans and animals appear to be largely due to the genes encoded by the virus, rather than mutations introduced by integration of the virus into the genome. Viral infections are often effectively controlled by the body’s immune system. In most individuals virus-encoded proteins will be expressed on the surface of infected cells and so be targets for destruction by the immune system. However newborn animals or individuals that are immuno-compromised appear to be most susceptible to developing tumorous responses to viral infection. As the retroviral vectors specified in this approval are replication-deficient, they are unable to propagate in cells (or humans). However, as noted above, there is a possibility the replicationcompetent retroviruses could be produced. The major effects of this situation would be that more cells could become infected and that the virus is transmitted to other individuals. Taking into account the advice received from an expert virologist, the Committee considers that controls and protocols specified in this decision will minimise the probability of infection of personnel. Other human health effects As a result of the low likelihood of the generation of replication-competent retroviruses, and the low likelihood of the survival of these organisms outside of the specific mediums in which they are maintained in the containment facility, the risks to human health of other than experimenters working with the organisms is considered to be negligible. Inseparable organisms In accordance with section 45(a)(ii) the Committee considered the effects of any inseparable organisms. In this case the issue of inseparable organisms includes any endogenous retroviruses present in cell lines into which DNA will be transferred by recombinant replication-deficient retroviral vectors. The cell lines to be utilised in these experiments are not certified as retrovirus free, and it is not considered to be feasible to test for the presence or absence of unknown retroviruses. In reviewing this application an expert virologist noted that it was uncommon for a recombination event between a recombinant replication-deficient retrovirus and an endogenous retrovirus in a packaging system to occur. And furthermore, that in the case of in vitro work, the Environmental Risk Management Authority Decision: Application GMD99002 Page 11 of 18 most significant effect of such an event would be from the point of view of the interpretation of experimental results, rather than from the perspective of a risk to human health. These comments were made in the context of comments noted above that personnel working with these organisms should be adopting appropriate containment measures on the assumption that the stocks and cells do potentially contain replication-competent retroviruses. Taking into account the additional controls imposed in this decision, the Committee was satisfied that occupational risks associated with the possibility of the development of replicationcompetent retroviruses as a result of the presence of endogenous retroviruses is low. However the Committee notes that the applicant should take heed of the comments of the reviewer with respect to assuming that replication-competent retroviruses may be present, and take any additional measures over and above the requirements of this approval in order to protect personnel from the risk of infection. Negligible risk Infection of personnel working with genetically modified retroviruses could result in adverse health effects, and although the likelihood of such an infection occurring is low, the Committee concluded that the occupational risk to workers could not be considered negligible. In evaluating this risk to workers the Committee considered the characteristics of this risk, noting that exposure to the risk was predominantly voluntary, any adverse effects to the health of the worker would likely not persist, any adverse effects would be unlikely to spread, any adverse effects would likely be treatable, and the risk is known and relatively well understood by those working with the organisms. The Committee also concluded that, taking into account the containment regime and additional controls imposed in this decision, the risks to the environment and wider public health associated with the development of these organisms, are negligible provided careful and strict management is maintained. Benefits The principal direct benefit to be derived from the development in containment of these organisms was identified as being the generation of scientific knowledge that may answer questions about how viruses cause cells to die. The value of this information was considered to be potentially significant in that it may lead to a better understanding of the normal cellular controls of growth and death. The Committee acknowledges that the degree of benefit to be derived from this research, as with all fundamental research, is difficult to quantify. However, that is not to say that the knowledge accumulated in the research is not beneficial as that information adds to the pool of knowledge from which other benefits flow, and the Committee accepts that exploratory research is an essential prerequisite for scientific progress. Environmental Risk Management Authority Decision: Application GMD99002 Page 12 of 18 In addition the Committee took into account other indirect benefits that may accrue from the work to be undertaken under this approval, including: possible future applications in therapeutic strategies in the treatment of disease such as cancer enabling New Zealand scientists to undertake innovative research projects maintaining New Zealand researchers’ involvement in the international scientific community maintaining New Zealand’s standing in international science. Environmental Risk Management Authority Decision: Application GMD99002 Page 13 of 18 Conclusion Pursuant to section 45(1)(a)(i) of the Act, the Committee is satisfied that this application is for one of the purposes specified in section 39(1) of the Act, being section 39(1)(a), The development of any genetically modified organism. In terms of clause 27 of the Methodology where risks are deemed not negligible, the Authority must take into account the extent to which the risks and any costs associated with the organism may be outweighed by benefits. And, in accordance with section 45(1)(a) may approve the application if the beneficial effects of having the organism in containment outweigh the adverse effects of the organism and any inseparable organism should the organism escape, taking account of the ability of the organism to escape from containment. In this case the Committee formed the view that the occupational risk to workers associated with the development of genetically modified retroviruses is not negligible. However, taking into account the characteristics of the risk, principally that the risk is voluntary and understood by personnel working with the organisms, and the low likelihood of any adverse effect occurring, the Committee considered that the risk to workers to be low, provided careful management is maintained. The Committee concluded that risks to the environment and wider public health from the development of these organisms in containment are negligible. In the absence of any costs to other parties, the Committee weighed the benefits of the proposal against occupational risk to workers, and concluded that the benefits, principally the generation of scientific knowledge to be gained outweigh the low risk to workers, taking into account the voluntary nature of the risk, and the additional risk management measures imposed in controls to which this approval is subject. The Committee is satisfied that the proposed containment regime, including compliance with MAF Biosecurity Authority Standard 154.03.02 and the relevant sections of AS/NZS 2243.3: 1995 Safety in Laboratories. Part 3: Microbiology, and the additional control conditions imposed in this decision will adequately contain the organism.
