Clinical Study of Recombinant Mycobacterium Tuberculosis Allergen

Status Completed

Clinical Trial Summary

The investigators recruit about 1800 cases participants who has signed ICF,then do some physical examinations for these people, including ecg, X-ray, HIV,blood pressure, specific gamma-interferon detection ,collection of medical history and the like .These subjects who meet the standard are considered as study population I. Population I are injected intradermally with ESAT6-CFP10 and Tuberculin purified protein derivative(TB-PPD) at different arm of the same subject and get at least 360 participants whose three kinds of detection result are all negative and are considered as study population II.Then,they are immune to the Bacillus Calmette -Guerin(BCG) vaccine or the placebo of the BCG.Do specific gamma-interferon detection before the skin test,then inject intradermally with ESAT6-CFP10 and TB-PPD at different arm of the same subject 12 weeks after immunity.

Clinical Trial Description

The investigators recruit about 1800 cases participants who has signed ICF,then do some physical examinations for these people, including ecg, X-ray, HIV,blood pressure, specific gamma-interferon detection(γ-IFN) ,collection of medical history and the like .These subjects who meet the standard are considered as study population I. Population I are injected intradermally with ESAT6-CFP10 and Tuberculin purified protein derivative(TB-PPD) at different arm of the same subject and get at least 360 participants whose three kinds of detection result are all negative(specific gamma-interferon detection ,TB-PPD and ESAT6-CFP10 ) and are considered as study population II.Then,they are immune to the Bacillus Calmette -Guerin(BCG) vaccine or the placebo of the BCG(BCG and the palcebo ratio of 2:1 ),they are incorporated into the Population III. Do specific gamma-interferon detection before the skin test,then inject intradermally with ESAT6-CFP10 and TB-PPD at different arm of the same subject 12 weeks after immunity. Evaluate the specificity of the ESAT6-CFP10 allergen by negative coincidence rate for BCG vaccinated crowd ,and the safety of ESAT6-CFP10 in all participant,and the correlation between ESAT6-CFP10 ,TB-PPD and γ-IFN. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
