PHase 3 data on Heplisav in adults aged 18-55 published in vaccine
Berkeley, CA - February 13, 2012 - Dynavax Technologies Corporation (NASDAQ: DVAX) announced today that results of a pivotal Phase 3 trial of HEPLISAV (HBV-10) were published online in the journal VACCINE. Data from this study will be used to support the HEPLISAV Biologics License Application (BLA) submission for an indication in adults 18-70 years of age. The article concludes that a short, two-dose regimen of HEPLISAV over 1 month was well-tolerated and induced superior immunogenicity and earlier onset of protection than a three-dose regimen of a licensed hepatitis B vaccine over 6 months.
The article entitled "Comparison of Safety and Immunogenicity of Two Doses of Investigational Hepatitis B Virus Surface Antigen Co-administered with an Immunostimulatory Phosphorothioate Oligodeoxyribonucleotide and Three Doses of a Licensed Hepatitis B Vaccine in Healthy Adults 18-55 Years of Age" describes the results from one of the two pivotal Phase 3 trials of HEPLISAV. Dr. Scott Halperin of Dalhousie University was the principal investigator and lead author. The trial compared the safety and immunogenicity of HEPLISAV with Engerix-B® in 2,415 adults randomized in a ratio of 3:1, HEPLISAV to Engerix-B. The seroprotection rate at the primary endpoint after 2 doses for HEPLISAV (95%) was significantly higher than after 3 doses for Engerix-B (81%). Superiority of the seroprotection rates for HEPLISAV was demonstrated at all time points measured.
Dynavax plans to submit the BLA for HEPLISAV by the middle of May for an indication in adults 18-70 years of age.
