Summary

The purpose of this study was to evaluate response to and safety of the HBV vaccine HEPLISAV-B in two study populations of people living with HIV: prior HBV vaccine recipients who are deemed non-responders and individuals who are naïve to HBV vaccination.

Detailed description

This phase III/IV study evaluated the response to and safety of the HBV vaccine HEPLISAV-B in two study populations of people living with HIV: prior HBV vaccine recipients who are deemed non-responders (Group A) and individuals who are naïve to HBV vaccination (Group B). The analyses were conducted as separate evaluations of the two study populations for all primary and secondary objectives. Group A (HBV vaccine non-responders) The study was designed as an open-label three-arm study to evaluate whether: 1. HEPLISAV-B vaccination given as a two-dose series achieves non-inferior seroprotection response (SPR) compared to standard dose ENGERIX-B. 2. HEPLISAV-B vaccination given as a three-dose series achieves superior SPR compared to standard dose ENGERIX-B. Participants were randomized in 1:1:1 ratio to the following study arms, stratified by sex at birth (male vs. female) and diabetes diagnosis status (yes vs. no): 2-CpG: Two doses of HEPLISAV-B at weeks 0 and 4. 3-CpG: Three doses of HEPLISAV-B at weeks 0, 4, and 24. 3-alum: Three doses of ENGERIX-B at weeks 0, 4, and 24. The target sample size in Group A was 561 participants, 187 participants in each arm. Group B (Naïve to HBV vaccination) Group B study was a single arm evaluation of vaccine response and safety of three doses of HEPLISAV-B. The target sample size was 73 participants. In both groups, participants were scheduled to attend several study visits through Week 72. All participants were to remain on their antiretroviral therapy (ART), not provided by the study, throughout the study. Visits included physical examinations and blood collection. For 7 days after each vaccination, participants were asked to record temperature and any reactions they experienced.
