Full Title: CCAB: Addressing the risk of microbial impurities in Biologics and certain Advanced Therapy Medicinal Products (ATMPs)
For parenteral drugs such as monoclonal antibodies, injectable oligonucleotides, and RNA- or DNA-based ATMPs, filtration using pore sizes ranging between 0.02 and 0.2 µm is the method of choice to reduce bioburden and ensure terminal sterilization of the drug product. While filtration efficiently removes intact microbial cells it does not remove subcellular microbial components like toxins, lipopeptide/lipoproteins, flagellin, bacterial and fungal DNA, cell wall polysaccharides, extracellular proteases or endoglycosidases. These microbial impurities can have a significant impact on product quality and patient safety when critical loads are exceeded during a contamination event. The CCAB approach described here enables a comprehensive assessment of these risks.
