About this study

Official title: A Randomized, Blinded, Positive Control Phase 1b Trial to Evaluate the Safety and Immunogenicity of a SARS-CoV-2 mRNA Chimera Vaccine (RQ3013) in Healthy Adults Completed a Two-dose Primary Series of Inactivated Vaccine

This is a phase 1b, randomized, double-blind, positive control trial in healthy adults, intended to evaluate the safety and immunogenicity profile of RQ3013 in healthy adults primed with a two-dose inactivated vaccine 6-9 months earlier. The study vaccine is administered IM in the upper arm deltoid as single booster shot on day 0.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing RQ3013 and Comirnaty in people with COVID-19, run by Walvax Biotechnology Co., Ltd..

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 4 inclusion and 23 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: status not confirmed, as of the sponsor's last update on 31 May 2022. Status can change between updates, so confirm with the study contact before making plans.

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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Shuyuan Yang ((+86)18687832269, ynwsysy@walvax.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Immediate AEs within 30 minutes after booster vaccination, solicited local and systemic AEs for within 7 days and unsolicited AEs within 28 days following booster vaccination (time frame: within 28 days following booster vaccination). 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 31 May 2022.
