What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Diphtheria, tetanus and acellular pertussis (component) combined vaccine (adsorbed)Biological

    Three doses of basic immunization were administered at 3, 4, and 5 months of age, and one dose of booster immunization was administered at 18-24 months of age, for a total of four doses. The administration route for experimental vaccine is intramuscular injection of 0.5ml into the lateral deltoid muscle of the upper arm.

  • Diphtheria, tetanus and acellular pertussis combined vaccine (adsorbed)Biological

    Three doses of basic immunization were administered at 3, 4, and 5 months of age, and one dose of booster immunization was administered at 18-24 months of age, for a total of four doses. The administration route for active control vaccine 1 is intramuscular injection of 0.5ml into the lateral deltoid muscle of the upper arm.

  • Diphtheria, tetanus, pertussis (acellular, component), poliomyelitis (inactivated) vaccine (adsorbed) and Haemophilus influenzae type b conjugate vaccineBiological

    Three doses of basic immunization were administered at 3, 4, and 5 months of age, and one dose of booster immunization was administered at 18-24 months of age, for a total of four doses. The administration route for active control vaccine 2 is through intramuscular injection of 0.5ml into the anterolateral side of the thigh or the upper arm.

What is being measured

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

  1. Immunogenicity results of experimental group and active control group (DTaP)

    Positive conversion rate (4-fold increase) of antibodies against diphtheria (anti D) and tetanus (anti T)

    Measured: 30 days after basic immunization

  2. Immunogenicity results of experimental group and active control group (DTaP-IPV//PRP-T)

    Positive conversion rate (4-fold increase) of pertussis toxin antibody (anti PT), pertussis filamentous hemagglutinin antibody (anti FHA) antibodies

    Measured: 30 days after basic immunization

  3. Immunogenicity results of experimental group

    Positive conversion rate of pertussis adhesin antibody (anti PRN)

    Measured: 30 days after basic immunization

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Diphtheria, tetanus and acellular pertussis (component) combined vaccine (adsorbed), Diphtheria, tetanus and acellular pertussis combined vaccine (adsorbed) and Diphtheria, tetanus, pertussis (acellular, component), poliomyelitis (inactivated) vaccine (adsorbed) and Haemophilus influenzae type b conjugate vaccine in people with Healthy Volunteers, run by Beijing Zhifei Lvzhu Biopharmaceutical 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 11 inclusion and 20 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: looking for participants now, as of the sponsor's last update on 3 Apr 2024. 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 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Wenjian Fang (+86-18611630252, fangwenjian@zhifeishengwu.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Immunogenicity results of experimental group and active control group (DTaP) (time frame: 30 days after basic immunization). 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?
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 Apr 2024.
