Clinical Study of Recombinant Mycobacterium Tuberculosis Fusion Protein for 65-year-olds and Above

A Multicenter, Randomized, Double-blind, Controlled Phase Ⅲ Trial of Recombinant Mycobacterium Tuberculosis Fusion Protein (EC) for the Diagnosis of Mycobacterium Tuberculosis Infection in 65-year-olds and Above

Source: ClinicalTrials.gov · Last updated 30 Apr 2026

Brief summary (registry, in English)

A multicenter, randomized, blind, controlled trial design was used to select 240 tuberculosis (TB) patients, 120 non-tuberculous community population with other lung diseases, and 420 healthy community population without other lung diseases who met the inclusion criteria of this study. Blood supply specific gamma-interferon (T-SPOT) detection was performed first. Then, EC and Purified Protein derivation of tuberculin (TB-PPD) skin tests were performed on both arms, and the recorded results were observed. The first 24 cases of TB patients, the first 12 cases of non-tuberculous community population with other lung diseases, and the first 42 cases of healthy community population without other lung diseases were included in the trial subgroup. Physical examination, blood routine, urine routine, liver and kidney function, and electrocardiogram tests were required before and 7 days after skin test after study number assignment.

Who cannot take part

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • Those with known or suspected (or high-risk occurrence possibility) immune impairment or abnormalities, such as those receiving immunosuppressants or immune booster therapy, receiving glucocorticoids, immunoglobulin preparations other than the gastrointestinal tract or blood products or plasma extracts within 1 month;
  • Those who are participating in other new drug clinical trials or have participated in any other new drug clinical trials within 3 months before this clinical trial;
  • Blood pressure range: systolic blood pressure ≥ 180 mmHg and (or) diastolic blood pressure ≥ 110 mmHg (those who take drugs are uncontrollable);

Other illness

  • Combined with the following serious diseases, such as advanced tumors, acute exacerbation of chronic obstructive pulmonary disease, acute or progressive liver disease or kidney disease, decompensated stage of congestive heart failure, autoimmune diseases (except those who do not need to use immune agents in the stable period), primary immunodeficiency diseases, etc.;
  • Those suffering from acute infectious diseases (such as measles, pertussis, influenza, pneumonia, etc.), acute conjunctivitis, acute otitis media, extensive skin diseases and allergies;
  • Those who have positive human immunodeficiency virus (HIV) antibody test results;

Lab values

  • Fasting blood glucose ≥ 10mmol/L after drug control;

Other

  • Any situation that the investigator believes is poor adherence or may affect the evaluation of the trial.

Who the study is looking for

  • 65 years old and above (≥ 65 years old), male or female, the subjects themselves voluntarily participate in this study, sign the informed consent form, and can understand and comply with the requirements of the trial protocol to participate in follow-up.
  • Normal underarm body temperature (\< 37.3 °C);
  • Tuberculosis patients: pulmonary tuberculosis patients and extrapulmonary tuberculosis patients diagnosed by researchers as confirmed cases of tuberculosis and clinically diagnosed cases. Refer to the "WS288-2017 Tuberculosis Diagnostic Criteria" to formulate the diagnostic criteria for pulmonary tuberculosis in this protocol, see Annex 1 for details; The diagnostic criteria for extrapulmonary tuberculosis were formulated with reference to the Technical Guidelines for Tuberculosis Prevention and Control in China (2021 edition of the Chinese Center for Disease Control and Prevention), as detailed in Annex 2.
  • Non-tuberculous community population with other lung diseases: there is a clear lung disease, but the study physician can exclude pulmonary tuberculosis based on the patient's clinical manifestations, chest imaging and laboratory tests. Diagnostic criteria for their main types of nontuberculous other lung diseases can be found in Annex 3;
  • Community healthy people without other lung diseases: those who have no history of tuberculosis, no suspicious symptoms of tuberculosis, no history of respiratory tract and recent respiratory symptoms, and no obvious abnormalities in both lungs on chest imaging (DR) examination; After consultation, there is no history of heart, liver, kidney, digestive tract, nervous system, or psychiatric abnormalities.
