VaxGen and BD to Jointly Evaluate Novel Dermal Injection Technology for Delivery of VaxGen's Anthrax Vaccine

BRISBANE, Calif., Feb. 21 (HSMN NewsFeed) -- VaxGen, Inc. (Pink Sheets: VXGN.PK ) announced today that they have entered into an agreement with BD (Becton, Dickinson and Company) (NYSE: BDX ) on a program to evaluate the potential advantages of using BD's Micro Injection technology to deliver VaxGen's recombinant anthrax vaccine candidate. Funding will be provided through BD's research contract with the Department of Defense (Award No. DAMD 17-03-2-0037).

The joint program is designed to determine if dermal administration (injection into the skin) of VaxGen's anthrax vaccine with the patented BD Micro Injection technology can enhance the immune response generated by the vaccine, versus standard intra-muscular injection, and/or reduce the required amount of vaccine to produce immunity. If the use of BD's technology in combination with VaxGen's anthrax vaccine proves safe and effective, and is approved by the U.S. Food and Drug Administration (FDA), it may be considered for use in future generations of VaxGen's recombinant anthrax vaccine as well as other vaccines. The evaluation being performed with BD will have no effect on VaxGen's existing contract to deliver 75 million doses of its anthrax vaccine to the U.S. government for civilian biodefense.

"This collaboration represents a shared commitment from VaxGen and BD to marshal the latest technology to further strengthen our nation's security," said Lance K. Gordon, Ph.D., VaxGen's President and Chief Executive Officer. "At VaxGen, we have every intention to continue exploring novel delivery devices and formulation technologies that show promise in enhancing our core vaccine technology. What we learn from our pursuit of dermal administration of our rPA anthrax vaccine may be applied to other much needed vaccines."

The collaboration will include a Phase I clinical trial to evaluate the use of BD's Micro Injection technology, featuring a microneedle technology, for vaccination with VaxGen's anthrax vaccine. The objectives of the study are to compare the safety and effectiveness of dermal injection versus traditional intramuscular administration of VaxGen's anthrax vaccine.

Dermal delivery has been studied in combination with a variety of vaccines. BD's Micro Injection technology is designed to easily and reliably deliver vaccine into the dermal layer of the skin with the potential to make dermal vaccination a practical alternative to intramuscular inoculation. There is evidence that delivery of vaccines specifically and accurately to the dermal tissue can produce an immune response that is more robust and/or requires less antigen or adjuvant than required with intramuscular inoculation.

Under the agreement, VaxGen will be responsible for providing vaccine, conducting clinical studies and regulatory submissions. BD will be responsible for providing devices incorporating the BD Micro Injection technology and for associated regulatory filings. BD will reimburse VaxGen for certain expenses associated with conducting the clinical studies and for serological assays associated with the study.
