About this study

Official title: A Randomized, Blinded, Placebo-Controlled, Dose Escalation Phase 1 Trial of Recombinant COVID-19 Trivalent (XBB.1+BQ.1.1+Prototype) Protein Vaccine (CHO Cell)(LYB002V14) in Booster Vaccination in Participants Aged 18 Years Old and Above

This is a randomized, blinded, and dose escalation phase I trial in males and non-pregnant females, starting at 18 years of age, inclusive, who are in good health and meet all eligibility criteria. This clinical trial is designed to assess the safety and immunogenicity of Recombinant COVID-19 Trivalent (XBB.1+BQ.1.1+Prototype) Protein Vaccine (CHO Cell)(LYB002V14).

Read the detailed description

The study is a randomized, blinded and dose escalation Phase I clinical trial. It will evaluate the safety and immunogenicity of 2 dose levels of recombinant COVID-19 trivalent (XBB.1+BQ.1.1+Prototype) protein vaccine (CHO Cell)(LYB002V14)in booster vaccination. Approximately 120 participants aged 18 years and older will be enrolled in this study. The subjects in each dose group will randomly receive an intramuscular (IM) injection of experimental vaccine or placebo on Days 0 in the deltoid muscle at 2:1 and will be followed through 12 months post vaccination.

Being tested
30μg dose of LYB002V14, 60μg dose of LYB002V14, placebo

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing 30μg dose of LYB002V14 and 60μg dose of LYB002V14 in people with SARS-CoV-2 and COVID-19 Vaccine, run by Guangzhou Patronus Biotech 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 6 inclusion and 10 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 26 Dec 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 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?

Contact Qin Yu, Master (18980602109, 908929936@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Adverse events and adverse reactions (time frame: Day 0 to Day 7). 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 26 Dec 2023.
