Report of the third conference on next-generation sequencing for adventitious virus detection in biologics for humans and animals()

Next-generation sequencing (NGS) has been proven to address some of the limitations of the current testing methods for adventitious virus detection in biologics. The International Alliance for Biological Standardization (IABS), the U.S. Food and Drug Administration (FDA), and the European Directorate for the Quality of Medicines and Healthcare (EDQM) co-organized the “3rd Conference on Next-generation Sequencing for Adventitious Virus Detection in Biologics for Humans and Animals”, which was held on September 27–28, 2022, in Rockville, Maryland, U.S.A. The meeting gathered international representatives from regulatory and public health authorities and other government agencies, industry, contract research organizations, and academia to present the current status of NGS applications and the progress on NGS standardization and validation for detection of viral adventitious agents in biologics, including human and animal vaccines, gene therapies, and biotherapeutics. Current regulatory expectations were discussed for developing a scientific consensus regarding using NGS for detection of adventitious viruses. Although there are ongoing improvements in the NGS workflow, the development of reference materials for facilitating method qualification and validation support the current use of NGS for adventitious virus detection.
