Dynavax Technologies Corporation: FDA Agrees With Hepatitis B Vaccine Findings
BERKELEY, CA--(Marketwire - July 28, 2011) - Dynavax Technologies Corporation (NASDAQ: DVAX) today announced that the Center for Biologics Evaluation and Research (CBER) of the U.S. Food and Drug Administration (FDA) advised the company that "CBER agrees that clinical consistency of three consecutively manufactured lots of HEPLISAV has been demonstrated." In a written communication to Dynavax, FDA noted that "Although lot consistency criteria were not met at the pre-specified time point of 4 weeks PLD (post last dose), lot consistency criteria were met 8 weeks PLD, the time point corresponding to the primary immunogenicity endpoint, as well as at several other time points."
According to Dr. Tyler Martin, President and Chief Medical Officer, "As expected, the FDA has confirmed our assessment of lot consistency in the Phase 3 trial we just announced. With their concurrence, we can now move forward towards our goal of preparing a BLA for submission by the end of the year for hyporesponsive populations aged 40 and older."
About HEPLISAV
HEPLISAV is an investigational adult hepatitis B vaccine. In an earlier 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.
