Viral Clearance

In-House Training

TRAINING OVERVIEW

when developing a process for the manufacture of therapeutical recombinant proteins expressed in mammalian cell lines, gene therapy and cell therapy products, the biotherapeutics should not generate a risk of viral contamination of the patients. In the past, there were cases of viral contaminations that had tremendous safety, supply and financial impacts.

Regulatory agencies expect then that the manufacturing processes are appropriately designed to incorporate steps able to remove and/or inactivate viruses that may have been unexpectedly introduced into the process. But moreover, those risks should be prevented by using safe raw and starting materials, segregating the manufacturing steps and controlling the manufacturing environment.

The purpose of the Master Class is to give an overview of the sources and impacts of viral contaminations of biotherapeutics, how to prevent those risks and how to evaluate the capability of the process to remove and/or inactivate potential viruses through viral clearance studies.

  • Understand the consequences linked to a contamination of mammalian cell cultures and biologicals with unexpected viruses from experiences reported by the bioindustry

  • Understand the regulatory expectation on preventing the risks of viral contaminations

  • How to prevent the risk of biotherapeutics to be contaminated with adventitious viruses?

  • Propose methods to build up a process with an adequate capability to remove /inactivate potential viruses

  • How to demonstrate the capability of the process to remove / inactivate viruses?

  • Process development scientists and managers

  • CMC development program managers

  • Manufacturing managers

  • Heads of Quality assurance

  • Drug Regulatory Affairs managers
