HEPLISAV-B® in Adults With End-Stage Renal Disease (ESRD) Undergoing Hemodialysis

Phase 1

Completed

• Conditions: End Stage Renal Disease on Hemodialysis (Diagnosis)
• Interventions: Drug: HEPLISAV-B®

• Registration Number: NCT03934736
• Lead Sponsor: Dynavax Technologies Corporation

Brief Summary

This is an open-label, single arm study design to evaluate HEPLISAV-B® in adults with ESRD who are initiating or undergoing hemodialysis.

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
HEPLISAV-B®	HEPLISAV-B®	A single dose of 0.5 mL HEPLISAV-B® administered intramuscularly in the deltoid muscle at Week 0 (Visit 1), Week 4 (Visit 2), Week 8 (Visit 3), and Week 16 (Visit 4).

Primary Outcome Measures

Name	Time	Method
Percentage of Subjects Reporting Clinically Significant Adverse Events - Medically-attended Adverse Events, Serious Adverse Events, and Immune-mediated Adverse Events of Special Interest	Week 0 (Visit 1) until Week 68 or early termination	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.
Seroprotection Rate (SPR) = Percentage of Participants Who Have a Seroprotective Immune Response	Week 20	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

Secondary Outcome Measures

Name	Time	Method
Serum Anti-HBsAg Geometric Mean Concentration (GMC)	Weeks 4, 8, 16, 20	Serum Anti-HBsAg Geometric Mean Concentration (GMC).
