About this study

Official title: Immunogenicity and Safety of a Recombinant Adenovirus Type-5-vectored COVID-19 Vaccine in Healthy Adults (18-80 Years Old) Finished 3 Doses Inactivated COVID-19 Vaccine: a Randomised, Double-blind, Parallel Controlled, Clinic Trial

COVID-19 is a novel coronavirus infection caused by respiratory droplets and contact transmission. With the spread of the epidemic, it has become a serious threat to global public health. China has launched a full range of vaccination including the third dose of homologous and sequential booster immunization. To further improve COVID-19 vaccine immunization strategy, we start the clinic research about sequential Immunization With Recombinant Adenovirus Type-5-vectored COVID-19 Vaccine in Health Adults Based on 3 Doses Inactivated COVID-19 Vaccine in Zhejiang province.

Being tested
Recombinant adenovirus type-5-vectored COVID-19 vaccine

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Recombinant adenovirus type-5-vectored COVID-19 vaccine in people with Immunogenicity and Safety of a Recombinant Adenovirus Type-5-vectored COVID-19 Vaccine Using for Sequential Immunization, run by Zhejiang Provincial Center for Disease Control and Prevention 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 4 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 13 May 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Contact Hangjie Zhang, phD (+86-13634159682, hjzhang@cdc.zj.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of adverse reactions (AR) in 0-14 days after immunization (time frame: 14 days). 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?

On the ClinicalTrials.gov record for NCT05373030, 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 13 May 2022.
