A Study of Quabodepistat-containing Regimens for the Treatment of Drug-resistant Pulmonary Tuberculosis

This is a Phase 3, randomized, open-label, active-controlled, multicenter trial evaluating the efficacy, safety, and tolerability of quabodepistat-containing regimens for the treatment of rifampicin-resistant or multidrug-resistant pulmonary tuberculosis. Participants are assigned to 1 of 2 cohorts based on fluoroquinolone susceptibility. In the fluoroquinolone-susceptible cohort, participants are randomized 1:1 to receive either a 4-month experimental regimen of bedaquiline, pretomanid, quabodepistat, and moxifloxacin or a 6-month control regimen of bedaquiline, pretomanid, linezolid, and moxifloxacin. In the fluoroquinolone-resistant cohort, participants are randomized 3:1 to receive either a 6-month experimental regimen of bedaquiline, pretomanid, and quabodepistat or a 6-month control regimen of bedaquiline, pretomanid, and linezolid. A total of approximately 532 participants are planned, including 432 participants in the fluoroquinolone-susceptible cohort and approximately 100 participants in the fluoroquinolone-resistant cohort. The primary efficacy endpoint is the proportion of participants with an unfavorable outcome by 12 months post-randomization. Prespecified agency-specific definitions are used for the classification of regimen changes, sputum culture conversion, relapse, and reinfection. All unfavorable outcome events will be confirmed by a blinded Endpoint Adjudication Committee.
