摘要: The primary adventitious agents of concern for biologics are examined in detail—prions, viruses, mycoplasmas, and bacteria/fungi microbes. three major risk control procedures these contaminating agents—barriers to entry, testing confirm absence, inactivation/removal—are discussed. Risk examples provided animal-derived materials used biologic manufacturing, cell culture manufacturing processes, biopharmaceutical production transgenic animals plants, natural sourced human plasma-derived proteins, virus-based biologics, cell-based medicines. In addition, lessons learned from previously reported infectious agent contaminations presented. Finally, some CMC strategic tips minimizing the overall contamination biologics.
