Dynavax Reports on Heplisav™ Pre-BLA Meeting With FDA

BERKELEY, CA--(Marketwire - Feb 2, 2012) - Dynavax Technologies Corporation (NASDAQ: DVAX) announced today that it met with the Food and Drug Administration (FDA) in a Pre-Biologics License Application (pre-BLA) meeting, and Dynavax and the FDA have agreed that the initial HEPLISAV BLA submission will be for an indication in healthy adults 18-70 years of age. This agreement represents a significant expansion of the previously anticipated population of healthy adults age 40 and over. In addition, it was confirmed that a supplemental BLA with an indication for patients with chronic kidney disease will be filed when the initial BLA is approved.

According to Dr. Tyler Martin, President and Chief Medical Officer of Dynavax, "This meeting with the FDA marks an important milestone for Dynavax. We have clarified the indication, scope and structure of the BLA submission. Following the submission, the BLA will undergo review and the HEPLISAV manufacturing facilities must be inspected prior to regulatory approval."

Dynavax said it is now making the required modifications to the BLA to support the expanded indication and plans to submit the BLA by the middle of May.


HEPLISAV is an investigational adult hepatitis B vaccine. In earlier Phase 3 trials, HEPLISAV demonstrated increased, rapid protection with fewer doses than current licensed vaccines. Dynavax has worldwide commercial rights to HEPLISAV. HEPLISAV combines hepatitis B surface antigen with a proprietary Toll-like Receptor 9 agonist known as ISS to enhance the immune response.
