About this study

Official title: A Multi-center, Double-blind, Randomized, Placebo Parallel Controlled, Safety and Tolerability Phase I Clinical Trial of Recombinant Novel Coronavirus Vaccine (CHO Cells) in Healthy People Between 18 and 59 Years of Age

In this trial, a total of 50 subjects were recruited; the test vaccines were divided into 3 groups, low-dose vaccine groups, high-dose vaccine groups, and placebo groups. The first-stage randomized participants in the low-dose group (20 cases) and the placebo group (5 cases) were evaluated for 7 days. After the 7-day safety data was evaluated and agreed by the DSMB, the second-stage study was conducted. Into the high-dose group (20 cases) and placebo group (5 cases) subjects; follow-up to 30 days, after the safety assessment by the investigator and consent, then inoculate the second dose. Observation was performed for 1.0 hour after the second dose. The researchers conducted a safety evaluation and agreed to follow-up after discharge.

What is being measured

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

  1. The number of adverse events after intramuscular injection

    The main observation methods of adverse reactions mainly include laboratory examination, local reactions and systemic reactions at the administration site, vital signs, blood routine, blood biochemistry, and urine routine.

    Measured: Up to one year after the last vaccination

Secondary outcomes (1)
  1. Immunogenic end point

    All subjects The levels of IL-2, IL-4, IL-5, IL-6 and IFN-γ levels before each vaccination, day 14 after the first vaccination, day 7 after the second vaccination, and 1 and 6 months after the entire vaccination.

    All subjects before each dose of vaccination, on the 14th day after the first dose, on the 7th day after the second and 1 month and 6 months after the full vaccination That Positive rate of New coronavirus (SARS-CoV-2) neutralizing antibody、S protein binding antibody (IgG) and RBD protein binding antibody (IgG).

    All subjects before each dose of vaccination, on the 14th day after the first dose, on the 7th day after the second and 1 month and 6 months after the full vaccination That Titer level and its multiplier than before exemption of New coronavirus (SARS-CoV-2) neutralizing antibody、S protein binding antibody (IgG) and RBD protein binding antibody (IgG).

    Measured: Within 6 months after the last dose of vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Recombinant new coronavirus vaccine (CHO cell) low-dose group and Recombinant new coronavirus vaccine (CHO cells) high-dose group in people with Coronavirus, run by Anhui Zhifei Longcom Biologic Pharmacy 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 5 inclusion and 26 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 Dec 2020. 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 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?

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 number of adverse events after intramuscular injection (time frame: Up to one year after the last vaccination). 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 NCT04445194, 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 3 Dec 2020.
