  Purpose

The purpose of this study is to further evaluate the safety and seroprotective immune response of a new investigational hepatitis B virus (HBV) vaccine, HEPLISAV™, in subjects 11-55 years old. The primary hypothesis is that HEPLISAV™ is well tolerated.

Primary Outcome Measures:
  • Occurrence of adverse events and local and systemic reaction rates [ Time Frame: 8 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Portion of subjects who have a seroprotective immune response (anti-HBsAg ≥ 10 milli-international unit (mIU)/ml) at Weeks 4, 8, 12 and 28. [ Time Frame: 28 weeks ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: 1 Biological: 1018 immunostimulatory sequence (ISS) immunostimulatory oligonucleotide with HBV surface antigen
Intramuscular (IM) injections on Day 0 and Week 4
Other Name: HEPLISAV™

Detailed Description:

Infection with hepatitis B virus (HBV) is a major global health problem. Worldwide, it is estimated that 2 billion people have been infected previously and 350 million are chronically infected. While acute HBV infection is associated with significant illness, the risk of chronic infection is of great importance since 5-10% of infected adults will not clear the infection after the initial phase of the illness. About 25% of people who do not initially clear the infection will later develop chronic active hepatitis.

This study will evaluate the safety and efficacy of two injections of HEPLISAV™ in subjects 11 to 55 years old. About 200 subjects will be included in the study. Once subjects have been consented and screened, they will receive a total of two injections over a 28-day period, with follow-up visits at 8, 12 and 28 weeks. Safety and tolerability will be evaluated by occurrence of adverse events, periodic laboratory tests, vital signs, and local/systemic reactogenicity.

Comparison: This study does not include a control treatment; all subjects will receive treatment with HEPLISAV™.
