About this study
Official title: For Tuberculosis (TB) Clinical Auxiliary Diagnosis of Recombinant Mycobacterium Tuberculosis Allergen ESAT6-CFP10 Dose Certain Phase III Clinical Research in Children Under the Age of 18 Years Old
In this clinical research,48 cases TB (Tuberculosis patients) participants and 48 cases non-TB participants with lung disease who all meet the standard are divided into different groups through a randomized and blind method. Every subject inject intradermally ESAT6-CFP10 and TB-PPD (tuberculin purified protein derivative) in different arms of the same person by blind method. Specific gama-interferon (γ-IFN) detection is needed before the injection.Measure the induration and (or) redness of longitudinal diameter size and transverse diameter vernier caliper by vernier caliper after injection 24h, 48h and 72h. At the same time, we observe all kind of adverse events in order to assess the safety of drug.
Read the detailed description
In this clinical research,we make sure of the safety in the crowd 5-18 years old firstly,then carry out the crowd of under 5 years old(including 5).
Firstly, 24 cases TB (Tuberculosis) participants and 24 cases non-TB participants with lung disease who are all 5-18 years old and meet the standard respectively are divided into different groups through a randomized and blind method.
- ESAT6-CFP10(10ug/ml) in left arm and TB-PPD in right arm
- ESAT6-CFP10(10ug/ml) in right arm and TB-PPD in left arm Inject intradermally ESAT6-CFP10 and TB-PPD in different arms of the same participant. For each of participant, the person in this clinical research, the study uniform is that every subject injects firstly left arm, observe no obvious adverse reaction, then another drug inject in right arm. Measure the induration and (or) redness of longitudinal diameter size and transverse diameter vernier caliper by vernier caliper after injection 24h, 48h and 72h. At the same time, we observe the vital signs (breathing, heart rate, blood pressure and temperature), local reactions (rash, pain, itching and skin mucous membrane) and a variety of adverse events.
Secondly, 24 cases TB (Tuberculosis) participants and 24 cases non-TB participants with lung disease who are all less than 5 years old are divided into two different groups and the procedure are as the same as 5-18 years old.
Finally, we calculate the sensitivity (positive coincidence rate) by TB (Tuberculosis patients), the specificity (negative coincidence rate) by non-TB participants with lung disease, and verify the safety and effectiveness of ESAT6-CFP10(10ug/ml) for the clinical auxiliary diagnosis of tuberculosis.

What is being measured
The primary outcome is the main question the study is designed to answer.
The diameter of induration or redness at the injection sites measured transversely to the long axis of the forearm 24 hours、48 hours and 72 hours after application of the agents
After skin test 1-3d,subjects's injection site may appear inuration or redness .The diameters of induration or redness are measured and recorded.The number of diameter of induration or redness<5mm,the result is negtive.If the number of diameter are not lower than 5mm,the result is positive.
Measured: From injections to 1-3 days after aplication
Secondary outcomes (1)
Number of participants with Adverse Events
Any AE of every subject appeared is recorded and traced after signing ICF,until remission of AE.
Measured: within 72h after injection two drug each participant

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing ESAT6-CFP10 in left arm and TB-PPD in right arm and ESAT6-CFP10 in right arm and TB-PPD in left arm in people with Tuberculosis Diagnosis, run by Anhui Zhifei Longcom Biologic Pharmacy Co., Ltd. at 4 sites 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 0 inclusion and 19 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 12 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites 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?
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 diameter of induration or redness at the injection sites measured transversely to the long axis of the forearm 24 hours、48 hours and 72 hours after application of the agents (time frame: From injections to 1-3 days after aplication). 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 NCT03027154, which also lists 4 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 12 Apr 2018; AzTrials last refreshed its copy on 8 Nov 2026.
