This is an open-label, single arm study design to evaluate HEPLISAV-B® in adults with ESRD who are initiating or undergoing hemodialysis.
Eligible participants will receive single doses of HEPLISAV-B® at Weeks 0, 4, 8, and 16 and will be followed through Week 68 or end of study (EOS). The study is designed to evaluate the immunogenicity over a 20-week period and safety over a 68-week period.

Percentage of Subjects Reporting Clinically Significant Adverse Events - Medically-attended Adverse Events, Serious Adverse Events, and Immune-mediated Adverse Events of Special Interest
Proportion 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.
Time frame: Week 0 (Visit 1) until Week 68 or early termination
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
Time frame: Week 20
Percentage of Subjects With Anti-HBs Concentration ≥100 mIU/mL
Percentage of subjects with anti-HBs concentration ≥100 mIU/mL.
Time frame: Weeks 4, 8, 16, 20
Serum Anti-HBsAg Geometric Mean Concentration (GMC)
Serum Anti-HBsAg Geometric Mean Concentration (GMC).
Time frame: Weeks 4, 8, 16, 20
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
Time frame: Weeks 4, 8, 16, 20
