Summary
This is a multicenter, randomized, double-blind, active-controlled Phase III study to evaluate the efficacy and safety of Sudapyridine (WX-081) combined with a background regimen (BR) in patients with rifampicin-resistant pulmonary tuberculosis. Approximately 450 participants will be screened over a period of up to 2 weeks and randomized in a 2:1 ratio to receive either Sudapyridine or bedaquiline, in combination with placebo tablets and BR, for 24 weeks. After the treatment period, participants will enter a background regimen period up to Week 72, during which they will continue to receive BR. A subset of participants will be included in the C-QT sub-study to assess intensive PK sampling and 12-lead ECG evaluations on Day 1 pre-dose, Day 14, and Week 24. The study aims to provide robust data to support the use of Sudapyridine as a treatment option for rifampicin-resistant pulmonary tuberculosis.

Interventions
Sudapyridine (WX-081) will be administered as a loading dose for 2 weeks (450 mg once daily for 7 days, followed by 300 mg once daily for 7 days) and a maintenance dose (150 mg once daily) from Week 3 to Week 24. The intervention is combined with background regimen (BR) and placebo for bedaquiline.
Bedaquiline will be administered as a loading dose for 2 weeks (400 mg once daily) and a maintenance dose (200 mg three times per week, with at least 48 hours between doses) from Week 3 to Week 24. The intervention is combined with background regimen (BR) and placebo for Sudapyridine.
