Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In the first stage,180 healthy subjects, 140 TB subjects and 40 non-TB subjects with lung diseases which meet the standard respectively 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.

Each subject's left and right arms will be randomly assigned to receive an intradermal injection of the experimental drug EEC and the control drug inoculated in both arms of the same person. A drug(EEC or EC) is injected in left arm first, observe 30 min and if no obvious adverse reaction ,then another drug (EEC or EC) will be injected in right arm. Observe and record the vital signs (breathing, heart rate, blood pressure ,temperature),the skin specific reaction (diameters of flush and induration of injection site) at 24h, 48h, 72h, 96h, and 7 days after skin test;local reactions (redness, pain, swelling, rash,itching) and a variety of adverse events. Evaluate the sensitivity , specificity and consistency rate of assay results of EEC, EC and IGRA in healthy subjects, TB patients and non-TB patients with lung diseases,determine the optimal dose of EEC for clinical auxiliary diagnosis of tuberculosis,and further evaluate the safety of EEC in healthy subjects, TB patients and non-TB patients with lung diseases.

In the second stage, 60 subjects aged 3-17 years old (30 cases) and 66-75 years old (30 cases) are enrolled, including 30 healthy subjects and 30 TB patients. Every subject is divided into different groups through a randomized, open label method, and receive a single intradermal injection of experimental drug (EEC) in one arm. Observe and record the vital signs (breathing, heart rate and temperature); laboratory examination and electrocardiogram (ECG) ;the skin specific reactions of injection site at 4h,8h,24h, 48h, 72h, 96h, and 7 days after skin test ; local reactions and a variety of adverse events,to further evaluate the safety and preliminary efficacy of EEC in people aged 3 to 75 years old.

TB subjects in 18-65 years old

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). The follow-up visit observation point is based on the completion time of the second dose of injection.
