About this study

Official title: A Phase III Randomized, Double-blind, Placebo-controlled Clinical Trial in 18 Years of Age and Above to Determine the Safety and Efficacy of ZF2001, a Recombinant Novel Coronavirus Vaccine (CHO Cell) for Prevention of COVID-19

A randomized, double-blind, placebo-controlled international multicenter clinical trial design will be adopted. A total of 29,000 subjects aged 18 years and above are planned to be recruited, including 750 subjects aged 18-59 years and 250 subjects aged 60 years and above in China; 21,000 subjects aged 18-59 years and 7,000 subjects aged 60 years and above will be recruited outside China. Safety and immunogenicity will be evaluated among the Chinese subjects, and efficacy, immunogenicity and safety will be evaluated among the subjects outside China. Among them, 750 subjects aged 18-59 and 250 subjects aged 60 and above from outside China and all subjects from China will be selected as the immunogenicity subgroup for immunogenicity bridging study. The IgG levels of SARS-COV-2 neutralizing antibody and RBD protein binding antibody will be detected by blood sampling before vaccination, 14 days and 6 months after full course of vaccination to evaluate the immunogenicity and immune persistence.

Read the detailed description

After signing the informed consent form, the volunteers aged 18 years and above will receive the relevant examinations after an inquiry by investigator of the medical history (including COVID-19 history), recent medication(vaccine) history, allergy history and concomitant medications, and demographic data collection by the investigators, including physical examination (skin and mucous membranes, lymph nodes, head, neck, chest, abdomen, spine/limbs), novel Coronavirus (SARS-COV-2) nucleic acid test and antibody test, urine pregnancy (women of childbearing age) test, and vital signs (blood pressure, axillary/oral temperature, pulse) evaluation.

Screening eligible subjects will be 1:1 randomly assigned to the experimental group and the placebo control group, and vaccinated as per the 0, 1, 2 month immunization schedule.

All adverse events (AEs) up to 30 minutes after each dose of vaccination, all AEs from 0 to 7 days (including both solicited and unsolicited), and all AES from 8 to 30 days (unsolicited) will be collected; All serious adverse events (SAEs) will be collected from the first dose of vaccination to 12 months after the whole vaccination.

The incidence rate and efficacy of any severity of COVID-9 of any severity 14 days after whole vaccination.

Blood samples (5ml) will be collected before the first dose of vaccination and 14 days and 6 months after the whole course of vaccination to detect neutralizing antibody of SARS-COV-2 and protein binding antibody IgG of receptor binding region (RBD) .

Being tested

What is being measured

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

  1. The endpoint of efficacy study

    The number of any severity of COVID-9 cases 14 days after whole vaccination

    Measured: 14 days to one year after whole vaccination

  2. The endpoint of safety study

    Analysis of adverse events from the first dose of vaccination until 30 days after full course of vaccination

    Measured: From the first dose of vaccination until 30 days after full course of vaccination

  3. The endpoint of safety study

    Analysis of serious adverse events from the first dose of vaccination until 12 months after full course of vaccination

    Measured: From the first dose of vaccination until 12 months after full course of vaccination

Secondary outcomes (2)
  1. The endpoint of efficacy study

    The number of severe and severity above COVID-19 cases 14 days after whole vaccination; The number of any severity of COVID-9 cases after first dose of vaccination; The number of COVID-19 cases of any severity in populations of different age group (18-59 years vs. 60 years and above) 14 days after whole vaccination.

    Measured: Up to one year after the vaccination

  2. Endpoint of immunogenicity and immune persistence study

    The level of neutralizing antibody to SARS-COV-2 and IgG level of RBD protein binding antibody at 14 days and 6 months after full course of vaccination.

    Measured: At 14 days and 6 months after full course of vaccination

A Phase 3 study testing Recombinant new coronavirus vaccine (CHO cell) group in people with Prevention of COVID-19 and Safety and Efficacy, run by Anhui Zhifei Longcom Biologic Pharmacy Co., Ltd. at 18 sites in 5 countries.

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 3 inclusion and 15 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 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 sites in Pakistan, Uzbekistan, Ecuador, Indonesia, 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 phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

The endpoint of efficacy study (time frame: 14 days to one year after whole vaccination). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04646590, which also lists 1 linked publication.

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 Jan 2022.
