About this study

Official title: Phase Ib Clinical Trial Evaluating the Safety and Immunogenicity of Freeze-dried Recombinant Tuberculosis Vaccine (AEC / BC02) in Healthy Adults

Single-center, single-dose, placebo-controlled, open-label trials were used to evaluate the safety and immunogenicity of low-dose adjuvants and low-dose vaccines in the upper arm deltoid muscle intramuscularly in the double negative population. Thirty (PPD-QFT-) healthy adult subjects aged 18-45 were selected and divided into placebo group, low-dose adjuvant group, and low-dose vaccine group. During the test, each subject must not change groups and inoculate drugs. Every two weeks (0-2-4-6-8-10 weeks), alternately inject a dose of placebo or left and right upper arm deltoid muscles. Low-dose adjuvant or low-dose vaccine, a total of 6 doses.

Low-dose adjuvant or low-dose vaccine, a total of 6 doses.

Collected adverse events within 14 days after each dose of vaccination, non-recruited adverse events within 30 days after the first dose of vaccination, subjects will receive 6 months follow-up after the last dose of vaccination, and study throughout Serious adverse events were recorded during the period. Immunogenicity will be assessed before the first dose, 24 hours after the third dose, before the fourth dose, 24 hours after the sixth dose, 1 month, and 6 months.

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 adverse events observed mainly from laboratory examination(including vital signs/routine blood/routingurine/Liver and kidney fuction/Electrocardiograghy and Chest X-ray detection),skin reactivity and local reaction after drug injection.Vital signs(breathing,pulse,blood pressure,body temperature) of each volunteer before each dose injection,and 30min after injection.Routine blood,routine urine,liver and kidney function,and ECG before first dose,fourth dose,and 7 days after the sixth time injection;skin reactivity and local reaction of rach volunteer at 30min before and after every injection.

    Measured: Up to 6 months after the sixth time injection

Secondary outcomes (1)
  1. Laboratory markers of immunity

    Evaluation of IFN-γand antibody level of before and after the immune,intracellular cytokine staining in blood .

    Measured: Up to 6 months after the sixth time injection

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Low-dose freeze-dried recombinant tuberculosis vaccine (AEC / BC02) and Low-dose adjuvant for freeze-dried recombinant tuberculosis vaccine (AEC / BC02) in people with Tuberculosis, 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 6 inclusion and 15 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 6 Sep 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. 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?

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: Up to 6 months after the sixth time injection). 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 NCT04239313, which also lists 3 linked publications.

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 6 Sep 2022.
