What is being measured

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

  1. Geometric mean titer (GMT) of SARS-CoV-2 neutralising antibody

    Measured: 28 days after each dose

  2. Proportion of participants achieving seroconversion for SARS-CoV-2 neutralising antibody

    Measured: 28 days after each dose

  3. Geometric mean increase (GMI) of SARS-CoV-2 neutralising antibodies

    Measured: 28 days after each dose

  4. Geometric mean titer (GMT) of SARS-CoV-2 specific IgG binding antibodies.

    Measured: 28 days after each dose

  5. Proportion of participants achieving seroconversion for SARS-CoV-2 specific IgG binding antibodies..

    Measured: 28 days after each dose

  6. Geometric mean increase (GMI) of SARS-CoV-2 specific IgG binding antibodies.

    Measured: 28 days after each dose

Secondary outcomes (5)
  1. Incidence of adverse events (AEs) after vaccination

    Percentage of participants with AEs for 28 days following each vaccination (Days 0, 28) by intensity, relevance.

    Measured: 28 days after the first or second vaccination

  2. Incidence of solicited adverse events (AEs) after vaccination

    Percentage of participants with solicited AEs for 30 minutes and 7 days following each vaccination (Days 0, 28) by intensity, relevance

    Measured: 30 minutes and 7 days after the first or second vaccination

  3. Incidence of unsolicited adverse events (AEs) after vaccination

    Percentage of participants with unsolicited AEs for 28 days following each vaccination (Days 0, 28) by intensity, relevance.

    Measured: 28 days after the first or second vaccination

  4. Proportion of subjects with abnormal markers of hematology, biochemistry, urinalysis, thyroid and coagulation parameters

    Safety Laboratory Values (Serum Chemistry, Hematology)

    Measured: Day 4 after first or second vaccination

  5. Incidence of serious AEs (SAEs) and adverse events of special interest (AESIs)

    Percentage of participants with SAEs or AESIs for 12month after last dose vaccination

    Measured: up to 12month after last dose vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing ZR-202-CoV in people with COVID-19, run by Shanghai Zerun Biotechnology Co.,Ltd 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 18 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 19 Apr 2023. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined 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.

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 titer (GMT) of SARS-CoV-2 neutralising antibody (time frame: 28 days after each dose). The study lists 6 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 19 Apr 2023.
