Dynavax Reports 2010 First Quarter Financial Results

Conference Call and Webcast Today at 4:30 pm EDT

BERKELEY, CA, May 06, 2010 (MARKETWIRE via COMTEX News Network) -- Dynavax Technologies Corporation (NASDAQ: DVAX) today reported financial results for the first quarter ended March 31, 2010, including $30.1 million in cash and cash equivalents. Total cash for the first quarter 2010 does not include $41 million in net proceeds from the public offering completed on April 16, 2010.

"With the completion of the recent financing, we are poised to achieve our most critical goals, including completion of the Phase 3 study required for submitting our BLA for HEPLISAV(TM), initiating clinical development for our Universal Flu and TLR autoimmune products, and positioning hepatitis B and C therapeutics for out-licensing," noted Dino Dina, M.D., President and CEO.

The tables included as part of this press release provide a reconciliation of GAAP revenues and operating expenses to pro forma revenues and operating expenses.

Conference Call

Dynavax will webcast a conference call today at 4:30 p.m. EDT (1:30 p.m. PDT). The live and archived webcast can be accessed by visiting the investor relations section of the Company's Web site at http://investors.dynavax.com/newsevents.cfm.

About HEPLISAV

HEPLISAV is an investigational adult hepatitis B vaccine. The vaccine candidate is being evaluated in two Phase 3 studies that are directed toward fulfilling licensure requirements in U.S., Canada and Europe. 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 Dynavax

Dynavax Technologies Corporation, a clinical-stage biopharmaceutical company, discovers and develops novel products to prevent and treat infectious diseases. The Company's lead product candidate is HEPLISAV, an investigational adult hepatitis B vaccine designed to enhance protection more rapidly and with fewer doses than current licensed vaccines.

(1) These pro forma amounts are intended to illustrate the Company's
    revenues including collaboration funding provided for the SDI programs
    and excluding certain non-cash items. The collaboration funding is
    reflected in the amount attributed to the noncontrolling interest in
    SDI in the Company's consolidated statement of operations, but would
    have been reported as revenue if SDI's results of operations were not
    consolidated with those of the Company. Management of the Company
    believes the pro forma results are a more useful measure of the
    Company's revenues because it provides investors the ability to
    evaluate the Company's operations in the manner that management uses
    to assess the continued progress of operating programs. These pro
    forma results are not in accordance with, or an alternative for,
    generally accepted accounting principles and may be different from pro
    forma measures used by other companies.
