Evaluation of the Novel Therapeutic Hepatitis B Virus Synthetic Long Peptide Vaccination ISA104 (HEB-PEP)
February 16, 2024 updated by: Dave Sprengers, Erasmus Medical Center
Phase I/II Study to Determine the Safety, Immunogenicity and Efficacy of the Therapeutic Hepatitis B Virus Synthetic Long Peptide Vaccination ISA104
The goal of this clinical trial is to test ISA104 in patients with chronic hepatitis B. The main question[s] it aims to answer are:
- How safe is ISA104?
- Does ISA104 induce immunity against hepatitis B virus?
Different doses of the vaccine ISA104 will be administered to participants. These participants are chronic HBV patients being actively treated with antiviral drugs.
Researchers will compare the ISA104 vaccine to a placebo.
