Ultra-Short Course Bedaquiline, Clofazimine, Pyrazinamide and Delamanid Versus Standard Therapy for Drug-Susceptible TB

The PRESCIENT trial is a Phase IIc, open-label, randomized trial that will compare a 12-week regimen of bedaquiline (BDQ), clofazimine (CFZ), pyrazinamide (PZA), and delamanid (DLM) with standard treatment for drug-susceptible pulmonary tuberculosis. Eligible participants will be randomized in a 1:1 ratio to BDQ, CFZ, PZA, and DLM (BCZD) or standard anti-TB therapy. Participants in the experimental arm with evidence of poor clinical response at the end of therapy will be re-treated with standard TB therapy. The primary analysis is a superiority efficacy comparison of time to liquid culture conversion through 8 weeks in the experimental (BCZD) arm vs. the standard therapy arm. The other key secondary outcome is safety.
