ABSTRACT=<p>Canadian academic and industry stakeholders are concerned about the inclusion of “virus-like particles or sub-viral particles” in the definition of <italic>New Substances Notification Regulations for Organisms (NSNR(O))</italic> which impacts clinical cell and gene therapy and commercialization. The requirement of an independent 120 days Environment and Climate Change Canada (ECCC) review preceding a Health Canada review on quality <italic>and</italic> environmental concerns places an additional burden on Sponsors submitting clinical trial applications (CTA) and/or New Drug Submissions (NDS). A workshop initiated by CellCAN and BIOTECanada with participants from Environment and Climate Change Canada, Health Canada, the Public Health Agency of Canada and Innovation, Science and Economic Development (Ottawa, March 19, 2018) with invited stakeholders discussed approaches to streamline the environmental review process. The following main recommendations were the focus of the workshop:
<list list-type="order"><list-item><p>A regulatory policy to clarify <italic>Canadian Environmental Protection Act</italic> (<italic>CEPA</italic>)'s definition of “living organism.” This is currently defined as “a substance that is an animate product of biotechnology.” A regulatory policy could potentially exempt “human cells touched by biotechnology for use in human medicinal products” from this definition to clarify any unintended overreach of <italic>CEPA</italic>, particularly as it applies to non-genetically modified cell therapies.</p></list-item><list-item><p>A guidance document to better interpret <italic>NSNR(O)</italic> Schedule 1 requirements by CTA/NDS sponsors to satisfy the environmental review process.</p></list-item><list-item><p>An amendment at the level of regulations, to the <italic>NSNR (O)</italic> to create a deferment to postpone environmental assessment of micro-organisms used in the manufacturing during investigational clinical trials (pre-market stage). The regulations would apply at the time of market authorization evaluation and review, when sufficient clinical data on vector shedding has been collected, as part of the investigational clinical trials.</p></list-item><list-item><p>Amendment to Schedule 4 of the <italic>CEPA</italic> to include the <italic>Food and Drugs Act</italic> and Regulations (<italic>Food and Drugs Act /FDR</italic>) as an exclusion to the application of CEPA. This would remove the current dual regulation of cell and gene therapies by both <italic>CEPA</italic> and <italic>Food and Drugs Act</italic> /<italic>FDR</italic>.</p></list-item></list></p><p>These recommendations and other options were discussed at the workshop. These recommendations if adopted will significantly streamline the current regulatory burden and harmonize environmental assessment requirements with other jurisdictions.</p>
