Clinical Trial Summary

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)

Intervention

Drug:
JDB0131
JDB0131 benzenesulfonate is a new anti tuberculosis compound based on delamanid. According to the existing results of pre clinical in vitro activity, in vivo efficacy, pharmacokinetics and safety in human body, JDB0131 benzenesulfonate has the same in vivo efficacy, better lung tissue distribution and better safety as delamanid. In December 2016, JDB0131 obtained the drug clinical approval issued by the CFDA, and were approved the clinical stage research that development of drug-resistant tuberculosis adaptation.
Delamanid
Delamanid is a new drug developed by Otsuka Pharmaceutical Co., Ltd. in Japan to treat multidrug resistant tuberculosis. In 2014, Delamanid was conditionally approved for marketing by the European Medicines Agency and recommended for use in adult MDR-TB patients who cannot form an effective regimen due to drug resistance or tolerance reasons. In the same year, WHO recommended that Delamanid be conditionally used for long-term treatment of adult MDR-TB. In 2016, the WHO recommended widening the age range for Delamanid to 6-17 years old. In March 2018, Delamanid was listed in China.
Ethylpyrazine rifampicide (II)
Ethylpyrazine rifampicide (II) is suitable for the first two months of intensive treatment of pulmonary tuberculosis with short-term therapy. This product is a compound preparation, consisting of 0.15g of rifampicin (C43H58N4O12), 0.075g of isoniazid (C6H7N3O), 0.4g of pyrazinamide (C5H5N3O), and 0.275g of ethambutol hydrochloride (C10H24N2O2 · 2HCl) per tablet.
