Naval Health Research Center Presents Preliminary Data on Biovest Bioreactor System

TAMPA, Fla. and MINNEAPOLIS--(BUSINESS WIRE)-- Biovest International, Inc. (OTCQB:BVTI) today announced that the U.S. Department of Defense (DoD), Naval Health Research Center (NHRC), presented encouraging preliminary results demonstrating that Biovest’s hollow fiber bio-manufacturing system is capable of efficiently producing a strain of pandemic A/H1N1 influenza virus. The results were presented this week at the 13th Annual Force Health Protection Conference in Phoenix, Arizona.

NHRC and Biovest investigations demonstrated that Biovest’s hollow fiber bioreactor system has the capability to produce high titer influenza virus (A/Mexico/4108/2009 H1N1) in MDCK cells, and growth variables can be manipulated to increase viral titer and production. This work utilizes Biovest’s Primer-HF® bioreactor, a disposable single-use hollow fiber instrument designed for producing research quantities of proteins or virus. Future NHRC studies are planned to be conducted in Biovest’s AutovaxID™ bioreactor, a scalable, automated, hollow fiber instrument designed for larger-scale GMP production applications.

Biovest’s President, Mr. Samuel S. Duffey, stated, “We have been working collaboratively with the DoD to expand the capabilities of our hollow fiber bioreactor systems, and the NHRC’s initial studies confirm that Biovest’s hollow fiber instruments hold the promise to play a vital role in the efficient cell culture production of viral vaccines.”
