Viral Vector Safety Testing

Viral vectors are widely used in gene therapy, vaccine development and gene editing. Safety testing is important to ensure the safety and efficacy of these gene therapy products. Creative Biogene has developed comprehensive viral vector safety characterization protocols during quality control for GMP manufacturing in accordance with regulatory requirements, encompassing all factors that may affect viral vector safety. These tests help ensure that process intermediates or final products are free of detectable contaminants that could pose a risk to patients, thereby providing customers with high-quality products for their viral vector-related program development.

Overview of Viral Vector Safety Testing

Safety testing of viral vectors is critical in GMP production. This testing is critical to identify any potential risks associated with viral vectors, such as toxicity, immunogenicity and integration with the host genome. Key parameters for safety testing include sterility, endotoxin, mycoplasma, exogenous viruses and the presence of replication-competent viruses. The viral vector safety testing we offer provides valuable information for risk assessment of viral vectors and helps in designing and optimizing vector systems in GMP manufacturing to minimize potential adverse effects. In addition, this testing is critical for regulatory approval of gene therapy products and vaccines. Our high- quality testing services can provide detailed safety data for preclinical/clinical studies of any viral vector-based therapeutic product.

Viral Vector Safety Testing Strategy at Creative Biogene

Creative Biogene offers viral vector safety testing that includes a wide range of assays, including cell-based assays, in vivo studies, genotoxicity, tumorigenicity, and biodistribution analysis. These assays help determine the tissue tropism and transduction efficiency of viral vectors, their replication capacity and potential off-target effects.

Testing Item	Method
Sterility testing	According to USP or EP recommendations to assess the bacterial or fungal load of the product.
