Approximately 54 healthy non-pregnant female and male adults aged 18-65 years inclusive are planned to be enrolled in the study. All subjects will have completed either a 2-dose primary vaccination series with Pfizer Biontech-BNT162b2 SARS-CoV-2 vaccine (P) or Moderna mRNA-1273 (M) (as authorized/approved or as investigational product in a clinical trial), OR have completed the primary series and one homologous booster of Pfizer Biontech-BNT162b2 or mRNA-1273 i.e, P-P-P and M-M-M; the last dose in all cases should have been administered at least 6 months prior to enrollment.~This study is composed of 3 dose groups, Groups 1, 2 and 3 per dose level. 18 eligible subjects in each dose group will receive RVM-V001 on Study Day 1 via intramuscular (IM) injection into deltoid muscle of the non-dominant arm.~Subjects will be sequentially assigned to a dose group beginning with Group 1 (10 µg RVM-V001) based on the timing of completion of screening. As a precautionary step, 3 sentinel subjects, at least one male and one female will be used within each dose group. Enrollment of each dose group will start with the 3 sentinel subjects. After at least 2 days from the time of study vaccine administration of the 3 sentinel subjects, the 2-day safety data will be collected and reviewed by the principal investigator and local medical monitor. Should there be no safety concerns, the remaining subjects in the same dose group can be enrolled.
Phase 1, open-label, dose-escalation study to evaluate the safety, tolerability, and immunogenicity of RVM-V001 administered as a single intramuscular injection in healthy adults. Three dose levels will be evaluated, with progression from low- to high-dose level based on the assessment of safety and tolerability. The study will be conducted at one or more sites in Australia.
