Detailed Summary

The purpose of the study was to evaluate the efficacy (how well the medicines work) and tolerability (whether participants stop treatment because of side effects from a drug) of an anti-TB treatment regimen that compared two doses of linezolid (LZD), combined with bedaquiline (BDQ), delamanid (DLM), and clofazimine (CFZ). This study also measured the level of LZD and BDQ in the participants' blood.
