Bioassays for Gene Therapy Products

Sidebar Image

ddPCR InstrumentGene therapy products are a unique class of biopharmaceuticals that offer exciting potential to treat life-threatening or debilitating diseases. Like all biopharmaceuticals, critical quality attributes of gene therapy products need to be carefully assessed to ensure product safety and efficacy. Unlike traditional protein therapeutics, efficacy of gene therapy products depends on multiple coordinated steps, including efficient cell entry, expression of the gene of interest, and proper biological function of the protein. Consequently, a matrix approach involving multiple bioassays - such as an infectivity assay combined with one or more functional assay(s) - are often required to sufficiently characterize the products. Oftentimes, the complexity of the mechanism of action also leads to higher intrinsic variability in bioassays, making them the most challenging assays to implement in quality control.

Eurofins BioPharma Product Testing network of laboratories offers extensive experience in bioassay development, optimization, phase appropriate method validation/transfer, as well as assay maintenance to support routine lot release and stability testing.
