Brief Summary

This is a randomized, blind, positive-controlled study to explore the skin test dosage of recombinant mycobacterium tuberculosis fusion protein ( EEC) in the population aged 18 to 65 years old , and to further evaluate the safety and preliminary efficacy of EEC in the population aged 3 to 75 years old. In the first stage,180 healthy subjects, 140 tuberculosis(TB)subjects and 40 non-TB subjects with lung diseases aged 18 to 65 years old are divided into different groups through a randomized, blind methods. Every group carry out a low-dose (2.5μg/ml) or high-dose (5μg/ml) study, with 180 subjects in each dose group .Every subject injects intradermally EEC and EC randomly in both arms of the same person. Evaluate the consistency of assay results of EEC, EC and Interferon-Gamma Release Assay(IGRA).Evaluate the sensitivity, specificity and consistency of assay results of EEC, EC and IGRA in healthy people, TB patients and non-TB patients with lung diseases, and determine the optimal dose of EEC for clinical auxiliary diagnosis of tuberculosis. In the second stage, 60 healthy subjects and TB subjects aged 3-17 years and 66-75 years old are divided into different groups through a randomized, open, single-arm method with the target dose. Evaluate the safety, tolerance and preliminary efficacy of target dose of EEC in healthy people and TB patients aged 3 to 17 years old and 66 to 75 years old.

Outcome Measures

Primary Outcomes (3)

  • Sensitivity of different doses of EEC and control EC in pulmonary tuberculosis patients aged 18 to 65 years ;

    Sensitivity (also known as the true positive rate which is defined as the percentage of actual disease that is correctly judged to be diseased according to the diagnostic criteria of the test)of different doses of EEC and control EC in patients with pulmonary tuberculosis aged 18 to 65 years old.

    7days after injection

  • specificity of different doses of EEC and control EC in healthy subjects aged 18 to 65 years and patients with non-tuberculous lung disease ;

    Specificity (also known as true negative rate which is defined as the percentage of actual disease-free patients correctly judged to be disease-free according to the diagnostic criteria of the test) of different doses of EEC and control EC in healthy people and patients with non-tuberculous lung disease aged 18 to 65 years old.

    7days after injection

  • The skin test site specific reaction at 4h,8h (only for stage 2);24h, 48h, 72h, 96h, and 7 days after skin test. Those with average diameter of induration/redness is ≥5 mm will be considered to positive.

    Endpoint of skin test site specific response evaluation which is defined as the skin test site symptom at 4 hour(only for stage 2), 8 hour(only for stage 2), 24 hour ,48 hour,72 hour,96 hour and 7 days after the skin test such as redness, induration, double ring, blister, necrosis, and lymphangitis (any symptoms of double ring, blister, necrosis, and lymphangitis were strongly positive).

    7days after injection

Secondary Outcomes (4)

  • Receiver operator characteristic curve(ROC) of different doses of EEC to evaluate the optimal diagnostic test cut-off value of the test drug.

    7days after injection

  • Area under the curve(AUC) of different doses of EEC to evaluate the optimal diagnostic test cut-off value of the test drug.

    7days after injection

  • In healthy people, patients with tuberculosis and patients with non-tuberculous lung diseases, the consistency rates of the three detection reagents EEC , EC and IGRA were evaluated respectively.

    7days after injection

  • Incidence of adverse events and serious adverse events at injection and non-injection sites,abnormal incidence of laboratory indicators and vital signs during the study period.

    7days after injection

Study Arms (5)

EXPERIMENTAL

140 TB subjects's left and right arms were randomly assigned to receive a single intradermal injection of 0.1 ml of the test drug (EEC,2.5 μg /ml or 5 μg /ml ) and the control drug (inoculated in both arms of the same body); all subjects were intradermally injected into the middle and lower 1/3 of the volar side of the forearm using the Mantoux method. injection. The time between skin tests on the left and right arms must be at least 30 minutes (skin test on the left arm first, then on the right arm).
