About this study

Official title: A Randomized, Double Blind, Positive Control Clinical Study to Evaluate the Immunogenicity and Safety of Sequential Immunization of Recombinant SARS-CoV-2 Fusion Protein Vaccine (V-01) Against COVID-19 in Healthy Adults Aged 18 Years and Older After the Vaccination of 2 Doses of Inactivated Vaccines

A Randomized, Double Blind, Positive Control Clinical Study to Evaluate the Immunogenicity and Safety of Sequential Immunization of Recombinant SARS-CoV-2 Fusion Protein Vaccine (V-01) Against COVID-19 in Healthy Adults Aged 18 Years and Older After the Vaccination of 2 Doses of Inactivated Vaccines

Read the detailed description

This is a Randomized, Double Blind, Positive Control exploratory clinical study. 150 participants aged 18 years and older who have completed the 2 doses of administration of inactive vaccines 6 months (±1 month) ago were enrolled in this study to evaluate the safety and immunogenicity of V-01.

The participants will be enrolled to test group A (V-01 10 μg), test group B (V-01 25 μg) and test group C (inactivated vaccine) by the ratio of 1:1:1. The participants received 1 dose of V-01 or inactivated vaccine base on the group.

The random stratification factor is age (18-59 years old vs. ≥ 60 years old).

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Recombinant SARS-CoV-2 Fusion Protein Vaccine 10μg, Recombinant SARS-CoV-2 Fusion Protein Vaccine 25μg and SARS-Cov-2 Vaccine Inactivated in people with COVID-19 Pandemic, run by Livzon Pharmaceutical Group Inc. at 1 site in China.

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 12 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 29 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

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?

Geometric Mean Titers of SARS-CoV-2 neutralizing antibodies (time frame: 28 days after booster immunization). 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 29 Mar 2022.
