Large-scale Production of Biologics is susceptible to microbial contamination because many manufacturing steps occur under non-sterile conditions in aqueous systems at ambient temperature or 2-8 °C under substantially neutral pH conditions. Regardless of where in the Drug Substance (DS) manufacture (manufacture of the Active Pharmaceutical Ingredient), or Drug Product (DP) manufacture (manufacture of the Final Drug, e.g. formulated mAbs filled in vials or syringes) they occur, microbial contaminations can have a significant impact on product quality and patient safety. Even after bioburden removal by 0.2 µm filtration subcellular microbial components like toxins, lipopeptide/lipoproteins, flagellin, bacterial and fungal DNA, cell wall polysaccharides, extracellular proteases or endoglycosidases remain in the product. Those microbial components potentially lead to toxic, allergic or inflammatory responses in humans or product degradation or modification. The CCAB approach described here enables a comprehensive assessment of these risks.

Merck KGaA, Darmstadt, Germany – A Leader in life science. Our purpose is to solve the toughest problems in life science by collaborating with the global scientific community – and through that, we aim to accelerate access to better health for people everywhere. We provide scientists and engineers with best-in-class lab materials, technologies and services. We offer more than a complete range of high quality microbiology testing solutions for the pharmaceutical, cosmetics, municipal water, beverages and food industries.

Testing for pyrogens and endotoxins is a critical step in ensuring the safety of parenteral pharmaceutical products and medical devices. The Monocyte Activation Test (MAT) can detect both endotoxin and non-endotoxin pyrogens in one test. Supported by many regulatory bodies, the robust MAT assay produces sensitive results based on the human reaction. With our new PyroMAT™ system, we provide a robust, reliable and standardized method for pyrogen detection.
