Core Tip

Core Tip: In the 2 patients reported here, the longer regimen, including 36-wk bedaquiline treatment, might be an option for patients with extensively drug-resistant tuberculosis. More studies are needed to explore the effectiveness and safety of prolonged use of bedaquiline for 36 wk vs standard 24 wk in the treatment of multidrug-resistant/ extensively drug-resistant tuberculosis and to investigate further the biomarkers and criteria indicative for extension of bedaquline to facilitate clinical use of this novel drug.
