What this trial studies

This Phase III clinical study evaluates the efficacy and safety of Sudapyridine (WX-081) in combination with a background regimen for patients with rifampicin-resistant pulmonary tuberculosis. Approximately 450 participants will be screened and randomized in a 2:1 ratio to receive either Sudapyridine or bedaquiline for 24 weeks, followed by a background regimen period lasting up to 72 weeks. The study employs a randomized, double-blind, active-controlled design to ensure robust data collection on treatment outcomes and safety. A subset of participants will also undergo intensive pharmacokinetic sampling and cardiac safety evaluations.

Who should consider this trial

Good fit: Ideal candidates include adults with a BMI between 15.0 and 28.0 kg/m2, weighing between 40 kg and 90 kg, and diagnosed with rifampicin-resistant pulmonary tuberculosis.

Not a fit: Patients with hematogenous disseminated pulmonary tuberculosis or those allergic to any study drug will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for patients suffering from rifampicin-resistant pulmonary tuberculosis.

How similar studies have performed: Other studies have shown promise in treating multidrug-resistant tuberculosis, but the specific use of Sudapyridine in this context is novel.
