BERKELEY, CA--(Marketwired - August 05, 2016) - Dynavax Technologies Corporation (NASDAQ: DVAX) announced today that the Vaccines and Related Biological Products Advisory Committee (VBRPAC) will review the Biologics License Application (BLA) for HEPLISAV-B™ [Hepatitis B Vaccine, Recombinant (Adjuvanted)] at its meeting on November 16, 2016. The FDA has indicated it will communicate questions for the VRBPAC to address closer in time to the meeting date. HEPLISAV-B, the company's vaccine candidate for immunization against infection caused by all known subtypes of hepatitis B virus in adults ages 18 years of age and older, is currently under FDA review, with a December 15, 2016 Prescription Drug User Fee Act (PDUFA) action date.
"The upcoming VBRPAC meeting is the next step towards our goal of obtaining regulatory approval for HEPLISAV-B and we are prepared for it," said Eddie Gray, chief executive officer of Dynavax. "The company looks forward to discussing HEPLISAV-B with the advisory committee and continuing to work closely with the FDA through the review process."
The VRBPAC reviews and evaluates data regarding the safety, efficacy, and appropriate use of vaccines and related biological products that are intended for use in the prevention, treatment, or diagnosis of human diseases.
About Hepatitis B
Hepatitis B is a viral disease of the liver that can become chronic and can lead to cirrhosis of the liver, hepatocellular carcinoma and death. In the U.S., the CDC estimates that approximately 20,000 hepatitis B infections continue to occur annually, with the vast majority occurring in adults. There is no cure for hepatitis B, and disease prevention through effective vaccination is critical to reducing the spread of the disease. Currently marketed hepatitis B vaccines are administered in three doses over a six-month schedule. Results of a published Vaccine Safety Datalink study showed that 54 percent of adults completed the currently available three-dose hepatitis B vaccine series in one year. Those who do not complete the series may not be adequately protected against hepatitis B.
HEPLISAV-B is an investigational adult hepatitis B vaccine that combines hepatitis B surface antigen with a proprietary Toll-like Receptor 9 agonist to enhance the immune response. HEPLISAV-B is administered in two doses over one month.
In Phase 3 trials, HEPLISAV-B demonstrated higher and earlier protection with fewer doses than a currently licensed hepatitis B vaccine. It also demonstrated a similar safety profile to the existing vaccine.
The investigational vaccine's safety profile is based on clinical trials that generated safety data from more than 14,000 participants. The most frequently reported local reaction was injection site pain. The most common systemic reactions were fatigue, headache and malaise, all of which were similar to an existing vaccine.
Dynavax has worldwide commercial rights to HEPLISAV-B.
