• To evaluate the safety of HEPLISAV compared to Engerix-B in subjects with CKD
• To compare immunogenicity with HEPLISAV and Engerix-B as measured by SPR at Weeks 4, 8, 12, 18, 24, 36, 44, and 52
• To compare immunogenicity of HEPLISAV and Engerix-B as measured by percentage of subjects with anti-HBsAg ≥ 100 mIU/mL at Weeks 4, 8, 12, 18, 24, 28, 36, 44 and 52
• To evaluate the immunogenicity of HEPLISAV compared to Engerix-B as measured by serum anti-HBsAg GMC at Weeks 4, 8, 12, 18, 24, 28, 36, 44 and 52
• To evaluate the immune response as measured by SPR of subjects with type II diabetes mellitus who receive HEPLISAV compared to Engerix-B at 4 weeks after the last injection (Week 28) |

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
The end of study date is defined as the date at which the last data point required for statistical analysis (ie, key safety and efficacy results for decision making) from the last patient is received at Dynavax.
The justification for the end of trial not being the last visit of the last subject is to allow the reporting of any key safety information (ie, laboratory values) that may have been previously overlooked. |
