About this study

Official title: A Clinical Study to Evaluate the Immunogenicity and Safety of Recombinant New Coronavirus Vaccine (CHO Cells) After Vaccination With Two Inactivated Vaccine in Healthy People Aged 18 and Above

Popular topic: Clinical study on immunogenicity and safety evaluation of sequentially enhanced immunity with recombinant Novel Coronavirus vaccine (CHO cells) Research purpose:Main purpose:To evaluate the immunogenicity of recombinant Novel Coronavirus vaccine (CHO cells) after sequential booster immunization in populations vaccinated with two doses of marketed Novel Coronavirus inactivated vaccine.Secondary purpose:To evaluate the safety of recombinant Novel Coronavirus vaccine (CHO cells) after sequential booster immunization in populations vaccinated with two doses of marketed Novel Coronavirus inactivated vaccine.

Overall design:An open experimental design was used in this study Study population:The study involved people 18 years of age and older. Test groups: All subjects recruited must have received two doses of Novel Coronavirus inactivated vaccine for 3 to 13 months (the interval between booster and basic immunization is divided into 3 groups:120 subjects at 3-4 months (91-120 days), 6-8 months (181-240 days) and 11-13 months (331-390 days) were vaccinated with one dose of recombinant Novel Coronavirus vaccine (CHO cells).

Read the detailed description

Overall design: An open experimental design was adopted in this study, and 360 subjects were planned to be enrolled.To evaluate the immunogenicity and safety of recombinant Novel Coronavirus vaccine (CHO cells) after sequential booster immunization in populations vaccinated with two doses of marketed Novel Coronavirus inactivated vaccine.

Intervention: This study involved people 18 years of age and older.All subjects recruited must have received two doses of Novel Coronavirus inactivated vaccine for 3 to 13 months (the interval between booster and basic immunization is divided into 3 groups:120 subjects at 3-4 months (91-120 days), 6-8 months (181-240 days) and 11-13 months (331-390 days) were vaccinated with one dose of recombinant Novel Coronavirus vaccine (CHO cells).

Immunogenicity observation:

Blood samples were collected from all subjects before and 14 days after experimental vaccine vaccination for humoral immunoassay.

Safety observation:

AE and SAE:

Collect all adverse events (AE) at least 30 minutes after vaccination, all AE (both solicitation and non-solicitation AE) from 0 to 7 days, and all AE (non-solicitation AE) from 8 to 30 days;All serious adverse events (SAE) within 1 month after vaccination with the experimental vaccine were collected.

  1. Solicitation AE (the following events occurring within 0-7 days after vaccination with experimental vaccine) :Adverse events at the inoculation site (local) : pain, itching, redness, swelling, rash, induration; Non-inoculated site (systemic) adverse events: fever, headache, fatigue/fatigue, diarrhea, nausea, vomiting, muscle pain (non-inoculated site), acute allergic reaction, cough.
  2. Vital signs and physical examination:All subjects were assessed for vital signs (blood pressure, axillary body temperature, pulse) during screening and axillary body temperature before trial vaccination. All subjects underwent physical examination (skin, cardiopulmonary auscultation) during the screening period.
  3. Collection of pregnancy events:Women of childbearing age should undergo a urine pregnancy test before enrollment (on the day of vaccination). Pregnancy events occurring within 1 month after trial vaccination were collected.
  4. ADE/VED (Antibody enhancement/vaccine Enhancement) Risk Monitoring:After receiving the experimental vaccine, if the subject is diagnosed with COVID-19, he/she should go to the hospital for hospitalization or be isolated in accordance with the local epidemic prevention and control requirements.A special investigation will be conducted for severe/critical/fatal cases, and the existence of ADE/VED will be analyzed based on the results of the special investigation.

Questions about this trial

What is this clinical trial studying?

A study testing Recombinant new coronavirus vaccine (CHO cell) group in people with Coronavirus Disease 2019, 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 3 inclusion and 22 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: finished, as of the sponsor's last update on 22 Oct 2021. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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: 1 months after full vaccination). The study lists 2 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 22 Oct 2021.
