UV-C Treatment—a New Procedure for Viral Inactivation

Life Sciences, Pharmaceutical, Pharma Manufacturing & Supply Chain,
  • Wednesday, December 11, 2013

Virus clearance studies are performed to ensure that the purification process has sufficient capability to remove and/or inactivate any viruses that may possibly contaminate the starting material. Selected steps are tested against a panel of viruses, including both enveloped and non-enveloped. It is typically more difficult to show viral clearance for non-enveloped viruses than enveloped viruses because of their smaller size and their relative resistance to physical-chemical inactivation. For these reasons, there is a need for an effective inactivation procedure for non-enveloped viruses.

UV-C treatment has been evaluated in the past for viral inactivation, but recent improvements in the technology have made it practical to use for the first time. Adding this step to a manufacturing process can provide an additional option for viral clearance for products where it is difficult to show adequate clearance. In addition, manufacturers planning to simplify their purification process may find this method beneficial as a means to maintain a sufficient viral clearance level with fewer purification steps.

During this presentation you will learn:

  • Design and function of the UVivatec instrument
  • Effectiveness of UV-C for inactivation of a number of different viruses in different virus families
  • Impact of UV-C irradiation on the product
  • How to integrate this technology into a manufacturing process
  • Results from a case study detailing the use of UVC as a solution to viral inactivation when other techniques failed for a virus-like-particle vaccine.

Dr. Todd Talarico, Vice President of Manufacturing, Medicago

Todd Talarico is Vice President of Manufacturing for Medicago and oversees the US and Canadian development and manufacturing operations. He has been responsible for Medicago-USA’s completion of an aggressive design-build project resulting in rapid construction and deployment of a facility designed to produce more than 10 million doses (in 30 days) of H1N1 vaccine expressed in and purified from tobacco plants.

Todd received a BS in Chemical Engineering from the Pennsylvania State University and a Ph.D. in Microbiology from North Carolina State University. He completed postdoctoral work at Burroughs Wellcome studying protein translocation and purification. Todd was the Director of Product Development at Apex Bioscience where he was responsible for a team that brought a PEGylated hemoglobin molecule from development to Phase III clinical trials.

He began working in the vaccine field with AlphaVax where he was a Senior Director responsible for development and process scale up of a virus replicon particle vaccine. While at AlphaVax, he was part of the team that delivered vaccines for colon/prostate cancer (CEA and PSMA), Her-2, Flu, CMV and HIV into clinical trials.
