About this study
Official title: Phase 1, Open-Label, Dose-Escalation Study to Evaluate the Safety, Tolerability, and Immunogenicity of RVM-V001 in Healthy Individuals Aged 18-65 Years Previously Vaccinated With BNT162b2 and mRNA-1273
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.
Read the detailed description
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.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing RVM-V001 10 µg, RVM-V001 30 µg and RVM-V001 60 µg in people with Infectious Disease and COVID-19, run by RVAC Medicines (US), Inc. at 2 sites in Australia.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 13 inclusion and 26 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 27 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Australia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early (reason given: The landscape of the study area changed, making it impossible to continue the study.). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of subjects with solicited adverse events (time frame: Day 1 to Day 8 post dose). The study lists 12 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jun 2023; AzTrials last refreshed its copy on 8 Nov 2026.
