AB This workshop was held on June 3, 2013, in Berlin, Germany, in conjunction with the PDA Virus & TSE Safety Forum 2013. A total of nine speakers presented on key considerations of virus filtration, including a historical overview and emerging trends in evaluating parvovirus filters. Several talks addressed understanding the mechanism of virus capture and breakthrough by filters, as well as addressing this risk by carefully controlling transmembrane pressure. Improvements to validation studies were proposed via the use of highly purified virus preparations, more relevant models such as Chinese Hamster Ovary retrovirus-like particles, as well as new assays for virus quantification. The workshop ended with a panel discussion covering a range of topics including virus breakthrough, up-stream media treatment, virus spike preparation quality control, and regulatory expectations.
