Safety and Immunogenicity of HEPLISAV™ a Hepatitis B Virus Vaccine in Adults on Hemodialysis

An Open-Label, Randomized, Multi-Center Study Comparing the Safety and Immunogenicity of HEPLISAV™ to Engerix-B® and Fendrix® in Adults on Hemodialysis Who Have Previously Received Hepatitis B Vaccination and Are Not Seroprotected

The purpose of this study is to compare the immune response to HEPLISAV™ booster injection with the immune response to Engerix-B® and Fendrix® booster vaccinations among patients with end stage renal disease (ESRD) on hemodialysis.

The immune response of HEPLISAV compared with Engerix-B and Fendrix and measured by seroprotection rate (SPR) at 4 weeks after the booster injection
