2021 PDA Virus Conference

Regulatory Updates
The first version of ICH Q5A was published in 1997 to regulate the Viral Safety Evaluation of Biotechnology
Products Derived from Cell Lines of Human or Animal Origin, then with a focus on interferons, monoclonal antibodies and recombinant DNA-derived products. A quarter of a century later, cell- and gene-based products, i.e. advanced therapies, now hold the promise of transforming medical practices, potentially offering cure rather treatment of medical conditions. The regulatory framework to support making theses advancements of biomedical research available to patients at adequate virus safety margins will be discussed.

Applications of Next Generation Sequencing, New Technologies, and Virus Detection
Adventitious viral contaminants are a major safety concern for biopharmaceutical manufactures; therefore, biopharmaceutical products undergo extensive adventitious agent testing to ensure that they are free of viral contamination. Traditional adventitious viral testing involves the use of cell culture or animals to detect viral contamination.  More recently, molecular techniques have been developed to detect adventitious virus yielding faster turnaround times and broader viral detection than the traditional methods.  In this session we will hear about molecular techniques such as next generation sequencing, and their potential to replace or supplement traditional adventitious virus tests.

Advanced Virus Detection Interest Group (AVDTIG) Session
The AVDTIG is an international effort focused on standards and standardization of next generation sequencing technologies for adventitious virus detection in biologics. The group has scientific discussions and collaborations to address technical and bioinformatics challenges in the NGS workflow, with the goal of facilitating broad applications of NGS for viral safety.  The session will include brief presentations on the background, ongoing activities, and achievements of the IG, and the status of ongoing collaborative studies for evaluating virus detection using NGS. The session will close with a member panel for audience Q&A and discussion.
