FDA Approves Dynavax BLA for Hepatitis B Vaccine

FDA has approved a Dynavax Technologies BLA for Heplisav-B [hepatitis b vaccine, recombinant (adjuvanted)] for immunization against hepatitis B infection in adults 18 years of age and older. Approval was based on data from three Phase 3 non-inferiority trials of nearly 10,000 adults who received Heplisav-B.
