Dynavax Technologies Corporation
The purpose of this study is to find out if a new investigational hepatitis B virus vaccine, HEPLISAV™, is safe and effective compared with Engerix-B® vaccine in subjects 11-55 years old. The primary hypothesis is that the seroprotective immune response of HEPLISAV™ is at least as good as that of Engerix-B®.

Condition Intervention Phase
Hepatitis B Biological: 1018 ISS with HBsAg and Placebo Biological: Engerix-B Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Prevention
Official Title: A Phase III Safety and Efficacy Study to Compare Immune Responses Following Injection With Either Two Doses of HEPLISAV™ or Three Doses of Engerix-B®

Primary Outcome Measures:
  • Proportion of subjects who have a seroprotective immune response (anti-HBsAg ≥ 10 milli-international unit (mIU)/ml after the final active injection in each treatment group (Week 12 for HEPLISAV™ and Week 28 for Engerix-B®) [ Time Frame: 28 weeks ]

Secondary Outcome Measures:
  • Rates of adverse events and local and systemic reactions to injections [ Time Frame: 28 weeks ]

Enrollment: 2428

Primary Completion Date: February 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1018 ISS with HBsAg and Placebo
0.5 mL 1018 ISS (immunostimulatory sequence) with HBsAg (hepatitis B surface antigen)
Biological: 1018 ISS with HBsAg and Placebo
Intramuscular (IM) injections on Week 0, Week 4 and Week 24; placebo (saline) injection at Week 24
Other Names:
  • Hepatitis B vaccine (recombinant), adjuvanted
Active Comparator: Engerix-B
1.0 mL Engerix-B
Biological: Engerix-B
Intramuscular (IM) injections on Week 0, Week 4 and Week 24
Other Name: Hepatitis B vaccine (recombinant)

Detailed Description:

This study will evaluate the safety and efficacy of two injections of HEPLISAV™, compared with three injections of a commercially available hepatitis B virus (HBV) vaccine, Engerix-B®, in subjects 11 to 55 years old. About 1,740 subjects will be included in the study. Once subjects are consented, screened, and randomized to treatment, all subjects will receive a total of three injections over a 24-week period, with a follow-up visit at 28 weeks. Subjects randomized to Engerix-B® will receive 3 injections of active vaccine, while subjects randomized to HEPLISAV™ will receive 2 injections of active vaccine plus 1 injection of placebo. Safety and tolerability will be evaluated by occurrence of adverse events, periodic laboratory tests, vital signs, and local/systemic reactogenicity.

Comparison: Subjects will receive treatment with either HEPLISAV™ or the comparator vaccine, Engerix-B®.
