0.5 mL HEPLISAV (20 mcg HBsAg and 3000 mcg 1018) administered intramuscularly in the deltoid muscle at Weeks 0, 4, and placebo (saline injection) at Week 24, followed by a 52-week safety follow-up from the last active dose of HEPLISAV.
Intramuscular injections at Week 0 and Week 4, plus a placebo injection at Week 24
Active Comparator: Engerix-B
1.0 mL Engerix-B (20 mcg HBsAg adsorbed on 500 mcg of aluminum hydroxide) administered intramuscularly in the deltoid muscle at Weeks 0, 4, and 24, followed by a 32-week safety follow-up from the last dose of Engerix-B.
Intramuscular injections at Week 0, Week 4, and Week 24
Other Name: Hepatitis B vaccine (recombinant)
- Percentage of Subjects Reporting Clinically Significant Adverse Events - Medically-attended Adverse Events, Serious Adverse Events, and Immune-mediated Adverse Events of Special Interest [ Time Frame: Week 56 ]The percentage of participants with Medically-attended adverse events (MAEs), Serious Adverse Events (SAEs), and immune-mediated Adverse Events of Special Interest (AESIs). MAEs are Adverse events (AEs) for which a subject sought medical attention at a doctor's office, clinic or study site, or emergency room, or was hospitalized. SAEs are AEs that met the definition of Serious per FDA regulations. Immune-mediated AESIs are AEs that were confirmed to be autoimmune in etiology.
- Percentage of Subjects With Type 2 Diabetes Mellitus Who Have a Seroprotective Immune Response [ Time Frame: Week 28 ]Percentage of subjects with type 2 diabetes mellitus who have a seroprotective immune response (anti-HBs ≥ 10 milli-international unit (mIU)/mL) who receive HEPLISAV compared with subjects who receive Engerix-B
