DRAMATIC (Duration Randomized Anti-MDR-TB And Tailored Intervention Clinical) Trial is a multicenter, randomized, partially blinded, four-arm, phase 2 trial that will examine an injectable- and pyrazinamide-sparing regimen of bedaquiline, delamanid, levofloxacin, linezolid, and clofazimine for treatment of MDR-TB. The DRAMATIC regimen limits the administration of linezolid to the initial 8 weeks of treatment, the window before linezolid-related neuropathy occurs. Animal and human studies provide evidence for the potential efficacy of this 5-drug regimen, but the optimal duration of treatment remains uncertain.
