Seroprotection Rate (SPR) = Percentage of Participants Who Have a Seroprotective Immune Response
SPR is the percentage of participants who have a seroprotective immune response (antibody level to anti-HBsAg greater than or equal to 10 milli-international unit \[mIU\]/mL) after HEPLISAV-B compared to that after Engerix-B.
Time frame: Week 28
Reactogenicity as Measured by the Percentage of Participants With Local and Systemic Post-injection Reactions Within 7 Days After Each Injection Visit
Local reactions include redness greater than or equal to 25 mm, swelling greater than or equal to 25 mm, and pain. Systemic reactions include malaise, headache, myalgia, fatigue, and fever (temperature greater than or equal to 38ºC). This table presents post-injection reactions at active injection visits only. Post-injection reactions after the third (placebo) injection visit in the HEPLISAV-B group are not included.
Time frame: 7 days after each injection visit (Weeks 0, 4, 8, and 24)
Seroprotection Rate (SPR) = Percentage of Participants Who Have a Seroprotective Immune Response at Weeks 4, 8, 12, 18, 24, 28, 36, 44, and 52
SPR is the percentage of participants who have a seroprotective immune response (antibody level to anti-HBsAg greater than or equal to 10 milli-international unit \[mIU\]/mL) after HEPLISAV-B compared to that after Engerix-B.
Time frame: Weeks 4, 8, 12, 18, 24, 28, 36, 44, and 52
Percentage of Participants With Anti-HBsAg Greater Than or Equal to 100 mIU/mL at Weeks 4, 8, 12, 18, 24, 28, 36, 44, and 52
Time frame: Weeks 4, 8, 12, 18, 24, 28, 36, 44, and 52
Serum Anti-HBsAg Geometric Mean Concentration (GMC) at Weeks 4, 8, 12, 18, 24, 28, 36, 44, and 52
Time frame: Weeks 4, 8, 12, 18, 24, 28, 36, 44, and 52

SPR of Participants With Type 2 Diabetes Mellitus at Week 28
SPR is the percentage of participants who have a seroprotective immune response (antibody level to anti-HBsAg greater than or equal to 10 milli-international unit \[mIU\]/mL) after HEPLISAV-B compared to that after Engerix-B.
Time frame: Week 28
