Trial overview

Official title: Safety and immunogenicity of GSK’s Rabies G SAM (CNE) vaccine [GSK3903133A] in healthy adults.
Trial description: 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.
Primary purpose:
Prevention
Trial design:
Sequential Assignment
Masking:
Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Allocation:
Randomized
