Clinical Study of JDB0131 Benzenesulfonate Tablets in Patients With Drug-sensitive Pulmonary Tuberculosis

A Randomized, Open, Multicenter, Phase IIa Clinical Study on the Early Bactericidal Activity, Safety, Tolerance and Pharmacokinetics of JDB0131 Benzenesulfonate Tablets in Drug Sensitive Pulmonary Tuberculosis Patients

A randomized, open, drug controlled design of experiments was used to evaluate the early bactericidal activity, safety, tolerance and pharmacokinetic characteristics of JDB0131 benzenesulfonate tablet taken orally by drug sensitive pulmonary tuberculosis patients. Five groups are proposed to be set up in this test (JDB0131 benzenesulfonate 100mg BID, JDB0131 benzenesulfonate 200mg QD, JDB0131 benzenesulfonate 200mg BID, anti tuberculosis drug fixed dose composite dosage QD is determined according to the weight of the study participants, and delamanid 100mg BID)

  6. ECG showed the following abnormalities: 1) QTcF>450 ms (corrected by Fridericia formula); 2) pathological Q wave (defined as >40ms or depth >0.4-0.5mV); 3) ECG suggests pre-excitation syndrome; 4) ECG suggests left bundle branch block or right bundle branch block; 5) ECG shows second- or third-degree heart block; 6) QRS duration > 120ms indoor conduction delay; 7) Sinus heart rate < bradycardia of 50bpm;
  7. Those who have any of the following cardiovascular diseases or other conditions within 6 months before enrollment: 1) myocardial infarction; 2) Cardiac surgery or coronary revascularization (coronary artery bypass grafting/percutaneous transluminal coronary angioplasty); 3) unstable angina; 4) congestive heart failure (New York Cardiology Society Cardiac Function Class III or IV); 5) transient ischemic attack or severe cerebrovascular disease;
  8. Anyone who is unable to comply with the uniform diet due to allergies or special dietary requirements;
  9. Those with a history of gastrointestinal surgery or resection that may affect the absorption and/or excretion of oral medications;
  10. Those who have abnormal ophthalmic examination during the screening period and are judged by the investigator to be unsuitable for participating in this trial;
  11. Depression: those with a score higher than 7 on the Hamilton Depression Scale (17 items, see Appendix 2);
  12. Those who are judged to have any unstable or severe cardiovascular, renal, liver, hematology, tumor, endocrine metabolism, psychiatric or rheumatic diseases and therefore consider them unsuitable to participate in this trial;
