Dynavax Technologies Corporation (DVAX)'s European Manufacturing Facility Approved for Commercial Production of HEPLISAV Hepatitis B Surface Antigen



12/9/2009 10:32:44 AM

BERKELEY, CA and DUSSELDORF, GERMANY--(Marketwire - December 09, 2009) -

Dynavax Technologies Corporation (NASDAQ: DVAX) announced today that its GMP manufacturing facility in Düsseldorf, Germany has been approved for the commercial production of hepatitis B surface antigen, a key component of HEPLISAV™, the Company's investigational adult hepatitis B vaccine. The approval comes as a result of an upgrade expanding production capacity. With an updated European Union GMP manufacturing license in place, Dynavax can meet the initial commercial production demands for the anticipated launch of HEPLISAV.

Dynavax's German subsidiary Rhein Biotech has manufactured the hepatitis B surface antigen for HEPLISAV clinical trials in this facility since 2006. The facility upgrade also enhances integrated product development and manufacturing services Rhein Biotech provides to third party partners.

About HEPLISAV

HEPLISAV is an investigational adult hepatitis B vaccine. In a completed pivotal Phase 3 trial, HEPLISAV demonstrated increased, rapid protection with fewer doses than current licensed vaccines. Dynavax has worldwide commercial rights to HEPLISAV and is developing the vaccine for large, high-value populations that are less responsive to current licensed vaccines, including individuals with chronic kidney disease. HEPLISAV combines hepatitis B surface antigen with a proprietary Toll-like Receptor 9 agonist known as ISS to enhance the immune response.

About Hepatitis B Vaccines

Currently available hepatitis B vaccines require three doses over six months to achieve full immunogenicity in healthy patient populations. Because compliance with this vaccine regimen is low, new vaccines are needed to provide increased protection in a shorter timeframe. Furthermore, currently available vaccines do not fully address the needs of several patient populations, including those with chronic kidney disease, HIV or chronic liver disease. In particular, patients with comprised immune systems require both rapid and enhanced protection, either because they are less responsive to conventional vaccine regimens or because they are at high risk of infection.

About Dynavax

The Company's lead product candidate is HEPLISAV, a Phase 3 investigational adult hepatitis B vaccine designed to provide more rapid and increased protection with fewer doses than current licensed vaccines.
