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

September 29, 2020 updated by: Anhui Zhifei Longcom Biologic Pharmacy Co., Ltd.

Phase III Clinical Study of Recombinant Mycobacterium Tuberculosis Allergen ESAT6-CFP10 on Healthy People Aged 18-65,Adopting Randomized Blinded and Parallel Controlled Method

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

At 24 hours after Intradermal injection with EC or TB-PPD
Number of study population III Negative for Reaction at 48 hours After intradermal injection with EC or TB-PPD
Time Frame: At 48 hours after Intradermal injection with EC or TB-PPD
At 48 hours after Intradermal injection with EC or TB-PPD

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
the number of participants with Adverse Events after Intradermal injection
Time Frame: within 48 hours after after Intradermal injection
