MANASSAS, Va.–(BUSINESS WIRE)–ATCC, the world’s premier biological materials management and standards organization, today announced that it has been awarded a task order with a ceiling value of $15.5 million, inclusive of base and options, by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH). Under this task order 75N93019D00002-75N93024F00001, ATCC will develop well-characterized challenge material (WCCM) for the In Vitro Assessment for Antimicrobial Activity (IVAAA) program. This program aims to evaluate candidate countermeasures against microbial pathogens and vectors, including those derived from clinical specimens. The assessments are conducted in vitro and focus on antiviral screening assays for biosafety level (BSL)-3/4 viruses relevant to human diseases, as well as other rapidly emerging viruses that employ similar assay methodologies.
Due to the rise in countermeasures requiring the use of well-characterized viral stocks for animal studies and human clinical trials, researchers are examining the potential impact of cell substrates on the genetic stability and quality of progeny virus following serial propagation. In mammalian cells, serially propagating viruses can lead to rapid increases in genetic variants and instability, which have been shown to impact the interpretation of data from animal studies as well as from clinical trials. Ensuring the genomic homogeneity of WCCM, as well as improving the production capacity of WCCM used in drug screening studies, is essential for therapeutic drug development.
