FDA Will Review New Dynavax Hepatitis B Virus Vaccine

alt

The U.S. Food and Drug Administration (FDA) has indicated that it will review for approval a new hepatitis B vaccine known as Heplisav.

Widespread immunization against hepatitis B virus (HBV) -- now part of the routine childhood vaccination series in the U.S. and much of the world -- has dramatically reduced infection rates over the past 2 decades. But researchers continue to work on new vaccines that are more effective and easier to administer.

Below is an edited excerpt from a Dynavax press release announcing the FDA's acceptance of its Heplisav review application.

Dynavax Announces FDA Acceptance of HEPLISAV BLA

Berkeley, CA -- June 26, 2012 -- Dynavax Technologies Corporation (NASDAQ: DVAX) today announced that the Food and Drug Administration (FDA) has accepted for review the U.S. Biologics License Application (BLA) for HEPLISAV, pursuing an indication for immunization against infection caused by all known subtypes of hepatitis B virus in adults 18 through 70 years of age.

Dynavax President and Chief Medical Officer, Tyler Martin, MD, said, "The FDA has established February 24, 2013, as the PDUFA action date. We look forward to working with the FDA in moving HEPLISAV through the regulatory review process over the next few months."

The company anticipates submitting a European Marketing Authorization Application (MAA) for HEPLISAV in the third quarter of 2012. Upon approval of the HEPLISAV BLA, Dynavax plans to submit a supplemental BLA for an indication in patients with chronic kidney disease.
