The public workshop is being cosponsored by FDA, CBER, and PDA, Inc. The goals of the public workshop are to discuss: (1) Current and new viral removal technologies; (2) issues related to the reuse of chromatographic columns with an emphasis on viral clearance requirements; (3) current opinions on the need to standardize quality attributes of viral preparations used as controls in spiking and infectivity assays; (4) current methods used to standardize or validate traditional infectivity assays; (5) implementation and acceptability of polymerase chain reaction (PCR), PCR enhanced reverse transcriptase, and real-time PCR-based viral assays, standardization and validation of these new assays, and (6) the potential of and issues related to bracket/matrix studies defining generic virus inactivation conditions. FDA expects that participation in this workshop will provide manufacturers a regulatory perspective on viral clearance and facilitate product development and approval.
