Cell therapy products (CTP) typically require full sterility, endotoxin and Mycoplasma testing before product release. Often this is not feasible with fresh cells, and sponsors may rely on rapid microbiological methods (RMM). RMM must be qualified in-house using the sponsor's facilities, equipment, consumables, cells and matrices to meet regulatory approval. Herein, we present a cost-effective strategy to conduct an in-house abbreviated qualification of a commercially available RMM kit to meet Health Canada regulatory requirements.
