Methods of inactivation of viruses using n-methlyglucamide and its derivatives

This disclosure relates to methods for use in inactivating viruses. The methods of inactivating viruses with N-methylglucamides is applicable to the purification process of biologically-active drugs such as protein subunits, proteins (enzymes, factors, etc.), recombinant proteins, antibodies, vaccine or gene therapeutic products. The detergents used in this method are based on multiple N-methylglucamide homologs, consisting of a hydrophilic glucose moiety and hydrophobic fatty acid tail, linked by an amide bond. Additionally, these sugar-based detergents are nonionic by nature, which do not disrupt the drug protein, plasma biologies, non-enveloped viral vaccine or adeno associated viral particles. A method of purifying a biological product solution of interest having an unidentified enveloped virus contaminant, including incubating a biological product solution of interest with a standard solution, inactivating any potential enveloped virus contaminant present in the biological product solution of step (a), measuring the inactivated virus present in the final solution of step (b), incubating a separate biological product solution of interest with a N-methylglucamide solution, measuring the inactivated virus present in the final solution of step (d), and comparing the results of the final solutions of step (c) and step (e).

CONTINUOUS FLOW, HIGH THROUGHPUT APPARATUS AND METHOD FOR INACTIVATING VIRUSES AND PATHOGENS IN HUMAN PLASMA
20240350691 · 2024-10-24 · ·

The present invention is for a continuous-flow pathogen reduction apparatus and method, based purely on pathogen inactivation physical principles, for controlling or eliminating trans fusion-transmittable infections from emerging pathogens, pandemic viruses, and bioterrorism threats. The invention inactivates both nonenveloped and enveloped viruses as well as pathogenic bacteria and parasites in human plasma and biologies, while retaining the natural bioactivity, integrity and potency of the treated biologic. The method uses critic al, near-critical or supercritical fluids for viral and pathogen reduction of plasma and biologies. The apparatus is designed to rapidly process high volumes of plasma and biologies with high levels of pathogen reduction in a continuous flow fashion.
