How to Build a Release Testing Strategy for Cell Therapy Products
A well-designed Release Testing strategy is essential for determining whether a cell therapy product meets predefined quality requirements before it is released for its intended use. Unlike conventional pharmaceuticals, cell therapies are complex biological products, and their quality can be influenced by starting material variability, manufacturing conditions, processing time, and storage. For biotechnology and pharmaceutical companies, Release Testing should not be treated as the final isolated step in manufacturing. The strongest strategy connects release assays with in-process testing , process knowledge, product characterization, and Good Manufacturing Practice controls. This creates a more complete understanding of product quality and helps reduce the risk of discovering critical issues only after manufacturing is complete. What Is Release Testing for Cell Therapy Products? Release Testing refers to the analytical and quality control activities used to confirm that a manufact...
