Clinical Study of Recombinant Mycobacterium Tuberculosis Allergen ESAT6-CFP10 on Healthy People Aged 18-65(III-healthy)
Study Details
Study Description
Brief 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.

Detailed 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.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: ESAT6-CFP10 in the right arm Each volunteer is intradermally injected two agents in different arms 12 weeks after Bacillus Calmette - Guerin (BCG) or placebo of BCG immunization :ESAT6-CFP10 in the right arm and TB-PPD in the left arm concomitantly,according to a randomisation scheme. |
Biological: Bacillus Calmette - Guerin
The participants are injection intradermally with 0.1ml ESAT6-CFP10(EC) in the right OR left arm and TB-PPD in the other arm(right OR left) after 12 weeks immunization of BCG .
Other Names:
Biological: placebo of Bacillus Calmette - Guerin
The participants are injection intradermally with 0.1ml ESAT6-CFP10(EC) in the right OR left arm and TB-PPD in the other arm(right OR left) after 12 weeks immunization of placebo of BCG .
