About this study

Official title: A Clinical Study to Evaluate the Safety and Immunogenicity of Sequential Immunization of Recombinant SARS-CoV-2 Fusion Protein Vaccine (V-01) in Healthy Participants Aged 18 Years and Older After the Vaccination of 2 Doses of Inactivated Vaccines

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

Read the detailed description

This is a single arm, open-label clinical study. 34 participants aged 18 years and older who have completed the 2 doses of administration of inactive vaccines will be enrolled in this study to evaluate the safety and immunogenicity of V-01.

The participants will be collected blood before immunization, on day 7, day 14, day 28, day 90 and 6 month to evaluate humoral immunity.

All adverse events (AEs) within 30 minutes and 0-7 days after booster immunization, and unsolicited AEs from 8 to 28 days after booster immunization, as well as SAEs and AESIs from the first vaccination to 12 months after booster immunization will be collected from all participants.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of adverse events (AEs)

    The incidence of adverse events (AEs) occured within 30 minutes, 0-7 days, 0-30 days after booster immunization, as well as SAEs and AESIs from the first vaccination to 12 months after booster immunization.

    Measured: Within 12 months after booster immunization.

  2. Geometric Mean Titer (GMT)

    GMT of SARS-CoV-2 neutralizing antibody on 14 days and 28 days after booster immunization

    Measured: 28 days after booster immunization

  3. Geometric Mean Increase (GMI)

    GMI of SARS-CoV-2 neutralizing antibody on 14 days and 28 days after booster immunization

    Measured: 28 days after booster immunization

  4. Seroconvension rate

    Seroconvension rate of SARS-CoV-2 neutralizing antibody on 14 days and 28 days after booster immunization

    Measured: 28 days after booster immunization

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Recombinant SARS-CoV-2 Fusion Protein Vaccine 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 13 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 3 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?

Incidence of adverse events (AEs) (time frame: Within 12 months after booster immunization.). The study lists 4 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 3 Mar 2022.
