Evaluation of an oral bedaquiline regimen for treating multidrug-resistant TB in China: a randomized trial.

Publication date: Apr 02, 2026

Bedaquiline (BDQ) is recommended in China as component of oral short-course regimens (SCR) for MDR-TB patients. However, the efficacy and safety of BDQ containing oral SCRs remain insufficiently validated in large-scale, well-designed clinical trials involving the Chinese population. A randomized, non-inferiority, open-label trial was conducted at 17 hospital clinics in China, enrolling adult patients with MDR-TB. Participants were assigned in a 1:1 ratio to receive either a 40-week oral BDQ-containing SCR or a 40-week oral non BDQ-containing SCR. The primary endpoint was the proportion of participants achieving favorable outcome at the end of treatment. The non-inferiority margin of the difference in proportion between the BDQ and control groups in the modified intent-to-treat (mITT) population was set at -15%. A total of 217 participants were randomized. Among 182 patients in the mITT population, the BDQ-containing SCR group achieved an 80. 0% favorable outcome compared to 59. 8% in the non-BDQ group, with an adjusted difference of 22. 27% (95% CI 9. 41-35. 13%). BDQ-containing SCR was also associated with higher proportions of modified favorable outcomes and cure rates. Additionally, BDQ-containing SCR resulted in a higher culture conversion rate at the end of treatment and a shorter time to culture conversion. Serious adverse events occurred in 16 of 110 participants (14. 5%) in the BDQ-containing SCR group and 25 of 107 participants (23. 4%) in the non-BDQ-containing SCR group. 40-week BDQ-SCR proved non-inferior and superior, safe, and well tolerated in Chinese patients with MDR-TB. Further investigation into the long-term safety and efficacy of the BDQ-containing regimen is still needed in China. gov NCT05306223. Prospectively registered on 16 March 2022.
