Biovest's AutovaxID(TM) Cleared for Commercial Sale

First and Only Device to Automate Production of Complex Biologics: Applications Include Vaccines and Personalized Medicines, Such as BiovaxID(TM)

TAMPA, Fla. & WORCESTER, Mass.--(HSMN NewsFeed)--May 10, 2006--A majority-owned subsidiary of Accentia Biopharmaceuticals, Inc. (NASDAQ:ABPI ), Biovest International, Inc. (OTCBB:BVTI ), has been informed by the United States Food and Drug Administration (FDA) that its patent-pending AutovaxID(TM) device requires no further review by the FDA, allowing Biovest to commence commercialization of the device. AutovaxID is, to the best of the Company's knowledge, the first and only instrument to enable the cost-effective and scalable production of cells or cell-derived products such as monoclonal antibodies for personalized medicine applications. Potential applications include production of vaccines to treat a variety of diseases, as well as stem-cell amplification for therapeutic uses. AutovaxID is a reusable device that hosts a companion single-use, disposable, closed-system chamber containing a hollow-fiber cell-growth cartridge. This unique instrument has the potential to replace conventional cell-growth chambers that require up to ten times as much laboratory space, as well as additional labor and increased expenses.

"This is an important advancement in the use of cell-culture techniques for production of complex biologics, especially those for personalized medicine applications," said Dr. Steve Arikian, Chairman and Chief Executive Officer of Biovest. "For the first time, with AutovaxID, such production is less susceptible to contamination, more reliable, and truly economical."

Biovest has manufactured and distributed patented hollow-fiber cell-culture technologies for more than 12 years, and AutovaxID is the Company's next-generation computerized host device. By automating the production process and using single-use, closed-system disposable cartridges, AutovaxID minimizes costly and error-prone manual monitoring and adjustments and reduces the need for large production facilities containing costly isolation suites and clean rooms. The new instrument is expected to be a significant enabling technology for the emerging field of personalized medicine by allowing Companies to process personalized therapeutics in far less costly facilities while still maintaining sterility and strict segregation of patient-specific materials.

Dr. Arikian commented: "Our market research suggests a very robust demand from university, biotech, pharmaceutical and diagnostic clients. We believe that this will be a key enabling technology for large segments of the monoclonal antibody production community worldwide. In our case at Biovest, the AutovaxID technology is being used to produce BiovaxID, the personalized anti-cancer vaccine we are developing in coordination with the National Cancer Institute for our pivotal phase 3 trial. AutovaxID will make it economically feasible to produce this personalized medicine as well as scale production in response to growing demand."
