Clinical trials

The treatment of rifampicin-resistant/multidrug-resistant pulmonary tuberculosis (RR-TB) is characterized by a long treatment course, a high incidence of adverse reactions, a low cure rate, and a high recurrence rate. This is related to the large number of drugs in the RR-TB treatment regimen, the high incidence of adverse reactions, and the long treatment course, which lead to poor patient compliance. There is an urgent need for new, effective, safe, and short-course anti-drug-resistant regimens. A 6-month short-course oral regimen containing pretomanid was launched in 2020 and was approved for marketing in China in March 2025. Currently, there have been multi-center studies on the treatment of rifampicin-resistant/multidrug-resistant pulmonary tuberculosis with the pretomanid regimen initiated by investigator-initiated trials (IIT) in China, but there are no studies on special populations. The diabetic population belongs to a special population, has a relatively high incidence rate in China, and is at high risk of tuberculosis. During the treatment process, they may be more likely to experience adverse reactions and poor outcomes than ordinary patients. This study is a prospective cohort clinical study. It is planned to enroll patients aged ≥12 years with RR/MTB-TB complicated by diabetes at our center. Guided by the results of rapid molecular drug susceptibility testing, both groups will be treated with a regimen consisting of bedaquiline, pretomanid, linezolid, and moxifloxacin for 6 months. The experimental group will be diabetic patients, and the control group will be non-diabetic patients. The efficacy and safety of the two groups will be evaluated to provide a basis for the treatment of a new short-course drug-resistant regimen for RR/MDR-TB in special populations in China.

This study aims to compare the efficacy and safety of a 6-month all-oral regimen including Bedaquiline (BDQ,B), Delamanid (DLM,D), Linezolid (LZD, L), and Levofloxacin (LFX,L) to the the standard long - course treatment regimen within the Chinese population. The main questions it aims to answer are: Is the efficacy of short regimen non-inferior to standard regimen? Is the short regimen safe enough to replace the standard regimen? Participants will: Be given with either short or standard regimen for RR-TB treatment Be asked to complete the scheduled visit as planned.

Rifampicin-resistant tuberculosis (RR-TB) is characterized by a long treatment course, high incidence of adverse reactions, low cure rate and high recurrence rate. This is related to the large number of drugs in the RR-TB treatment regimen, high incidence of adverse reactions and long treatment course, which leads to poor patient compliance. There is an urgent need for new, effective and safe short-course regimens for drug-resistant tuberculosis. A 6-month short-course oral regimen containing pretomanid was introduced in 2020. However, as pretomanid is not yet available in China, it has not been verified and promoted in China. Pretomanid is expected to be launched in China in 2025, and it is urgent to evaluate the application of the new short-course regimen containing pretomanid in the Chinese population. This study is a prospective, randomized, controlled clinical trial. It plans to include RR-TB patients aged ≥12 years in multiple domestic centers. Under the guidance of rapid molecular drug susceptibility test results, the experimental group will be treated with bedaquiline, pretomanid, linezolid and moxifloxacin for 6 months, while the control group will be treated with bedaquiline, delamanid, linezolid and levofloxacin or bedaquiline, delamanid, linezolid and clofazimine for 6 months, depending on the susceptibility to fluoroquinolones. For patients with unknown susceptibility to fluoroquinolones, bedaquiline, delamanid, linezolid, levofloxacin and clofazimine will be used for 6 months. The efficacy and safety will be evaluated to provide a basis for the introduction and implementation of new short-course regimens for RR-TB in China.
