The purpose of this study was to find out if a new investigational hepatitis B virus vaccine, HEPLISAV™, was 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®.

Primary Outcome Measures:
  • Proportion of subjects who have a seroprotective immune response (anti-HBsAg ≥ 10 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 ] [ Designated as safety issue: No ]

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

Detailed Description:

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

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