Dynavax Announces Termination of Partnership with Merck for
HEPLISAV™ Hepatitis B Vaccine
- All Rights Revert to Dynavax-
BERKELEY, CA - December 19, 2008 - Dynavax Technologies Corporation (Nasdaq: DVAX) today announced the termination of a global license and development collaboration agreement with Merck & Co., Inc. for HEPLISAV(TM), a Phase 3 hepatitis B virus (HBV) vaccine. All rights to develop and commercialize HEPLISAV revert to Dynavax.
Dynavax will continue to evaluate regulatory options for the development of HEPLISAV indicated for adults outside of the United States and for the global end-stage renal disease markets, which the Company estimates represent approximately 70% of the total market opportunity for this vaccine. If the regulatory feedback is favorable, Dynavax plans to pursue a new partner or financing arrangement to support the completion of HEPLISAV's development for these markets.
"We believe the economics for HEPLISAV, which has been shown to be clinically superior in our trials, favor identifying an appropriate regulatory path in the U.S. and Europe," commented Dino Dina, M.D., President and Chief Executive Officer of Dynavax. "In the first quarter of 2009, we expect to gain additional insight into the regulatory path for HEPLISAV that will enable us to evaluate further development and pursue partnering agreements with potential collaborators or investors. Independently of HEPLISAV, with our current cash position and strong pharmaceutical partnerships, we have the ability to continue to advance our diversified, well-funded pipeline of products to position Dynavax for future success."
Update to 2008 Cash Outlook
Dynavax's consolidated cash, cash equivalents, marketable securities and investments held by Symphony Dynamo, Inc., or total cash, is projected to be over $65 million at December 31, 2008, an increase from the previous guidance of over $50 million. This increase is due to the $10 million initial payment under Dynavax's worldwide strategic alliance with GlaxoSmithKline as well as the Company's conservatively managed cash burn rate. Due to the termination of the Merck partnership, Dynavax anticipates that it will accelerate the recognition of approximately $31 million of non-cash revenue previously reported as deferred revenue.

About HEPLISAV
HEPLISAV is a Phase 3 hepatitis B vaccine that combines HBV surface antigen (HBsAg) with Dynavax's proprietary immunostimulatory sequences (ISS), which specifically target Toll-Like
Receptor 9 (TLR9) to stimulate an innate immune response. Clinical data demonstrate HEPLISAV's highly effective protection against HBV with a more rapid onset of protection, superior 2-dose regimen, and longer lasting seroprotection compared to current vaccines. In a recent Phase 3 trial, 95% of subjects receiving 2 doses of HEPLISAV were seroprotected compared to 81% of subjects receiving 3 doses of Engerix-B. In 9 clinical trials conducted over a period of nearly 10 years, a total of approximately 2,500 individuals have been vaccinated with more than 5,000 doses of HEPLISAV.
In October 2008, the U.S. Food and Drug Administration (FDA) requested additional information prior to considering further development of HEPLISAV in end-stage renal disease patients but advised that the balance of risk versus potential benefit no longer favors continued clinical evaluation of HEPLISAV in healthy adults and children. The clinical hold on the two U.S. IND Applications for HEPLISAV has been in effect since March 2008 following the FDA's request for a complete review of safety data, including all available information about a single case of Wegener's granulomatosis reported in a Phase 3 clinical trial.
HEPLISAV is not on clinical hold in any market outside of the U.S.
