An Industry Proposal for a Cell and Gene Therapy Safety Data Sheet.

Introduction: A safety data sheet (SDS) is an established hazard communication tool for chemicals, for which no comparable document exists in the biotherapeutics industry. As the cell and gene therapy (CGT) field expands, industry leaders have identified a growing need to address this gap in communication of the unique occupational health and safety risks posed by CGT materials and products.

Methods: Following the sections of a traditional chemical SDS, information was modified by industry subject matter experts, relevant to CGT biological materials.

Environmental Health and Safety Offers a Biosafety Risk Assessment for a Theoretical Model of a Gene Therapy Process Transfer from Research and Development to Large-Scale Manufacturing.

Introduction: This article provides a strategy by which a manufacturing process with a Biosafety Level 2 (BL2) designation can be downgraded to Biosafety Level 1 (BL1). The principles of the downgrading process are based on the robust contamination controls in clinical and commercial manufacturing, which typically are not part of Research and Development processes. These strict requirements along with the application of current Good Manufacturing Practice (cGMP) principles provide a framework by which processes can be suitably managed and controlled to mitigate biohazard risk, specifically for cell lines that may be contaminated with human pathogenic viral agents.

Environmental Health and Biosafety Risk Assessment Guidance for Commercial-Scale Cell and Gene Therapy Manufacturing.

Introduction: This article aims to identify best practices, improve risk controls, and aid regulatory agencies in developing guidance for environmental and biosafety risk assessment for commercial-scale cell and gene therapy manufacturing.

Methods: A cross-functional team should start with hazard classification and testing requirements for materials used or generated by the process and process hazard characterization.

Results: The team develops a safety profile of the process to mitigate risks, including: product biological contamination risk and process controls, including raw materials, facilities, operator and environmental controls, and method of detection;a technical review of the process to evaluate the operational and engineering controls;monitoring systems to mitigate the risk of failure and/or breach of the system, preventing the release of material to the facility or operator exposure;site sanitization strategy and facility containment measures, including engineering designs, air handling systems, spill containment measures, surface cleanability, waste flows, and decontamination practices;a review of site practices, including process, employee, material and waste flows, staff training, controlled access, operator gowning, and emergency response plans/measures.
