NCT04062669

Brief Summary

The purpose of this first time-in-human (FTiH) study is to evaluate the safety, reactogenicity and immunogenicity of different dose levels of an experimental rabies glycoprotein G (RG) vaccine (RG-SAM \[CNE\] vaccine), made using a new technology, when administered intramuscularly (IM) on a 0, 2, 6 \*-month schedule to healthy adults. \* There will be no vaccinations with the third dose of any of the study treatments.

Masking Details
In Part 1 of the study, only data during the primary vaccination phase (from study start to Day 91) will be collected in an observer-blind manner. By observer-blind, it is meant that the vaccines recipient and those responsible for the evaluation of any study endpoint will all be unaware of which vaccine was administered. For Part 1, the study will be observer-blind until Day 91. When the Day 91 analysis will result in unblinding of all the subjects to the sponsor. Therefore, the study cannot be considered observer-blind beyond Day 91 and will be conducted in a single-blind\* manner thereafter; with all subjects remaining blinded up to study conclusion (Month 14). For Part 2, the study will be conducted in open-label manner from study start to study conclusion. \*Due to the recent COVID-19 pandemic, the study will be fully unblinded from study start to study conclusion to allow all subject treatments to be known to the team and investigators, thereby facilitating rapid safety assessment.
