ZeNix is a clinical trial testing the BPaL regimen, which consists of pretomanid, bedaquiline, and linezolid. Zenix will evaluate whether the efficacy of the BPaL drug regimen can be maintained, while reducing toxicity, through a lower dose and shorter duration of linezolid.
ZeNix is a successor to Nix-TB, a pivotal trial of the BPaL regimen, which was recently approved by US FDA for treatment of adults with extensively drug resistant, treatment-intolerant or nonresponsive multidrug resistant pulmonary TB. Zenix tests a version of BPaL with a lower dose and shorter duration of linezolid, to determine whether the efficacy of BPaL can be maintained while reducing toxicity. Zenix enrolls participants with XDR-TB at sites in Africa and Eastern Europe.
