New trial evaluates whether the efficacy of the BPaL drug regimen can be maintained with reduced toxicity
“TB Alliance has announced the start of a clinical trial of a three-drug regimen to treat extensively drug resistant tuberculosis (XDR-TB)—one of the deadliest forms of tuberculosis (TB)—and those with pre-XDR-TB and multi-drug resident TB (MDR-TB) whose prior treatment has failed or who have not tolerated their treatment.
The trial, called ZeNix, will evaluate whether the efficacy of the BPaL (bedaquiline, pretomanid and linezolid) drug regimen can be maintained, while reducing toxicity by testing a lower dose and shorter duration of the drug linezolid. The first ZeNix patients have been enrolled in Georgia and South Africa, with sites in Russia joining later in 2018.
‘Too few people with XDR-TB are successfully cured with the current treatments,’ said Dr. Mel Spigelman, president and CEO of TB Alliance. ‘The present treatments take far too long and are made up of complex patchworks of drugs, many of which are toxic or ineffective—further contributing to TB drug resistance. With ZeNix, we are attempting to optimize a potentially safer, quicker and less complicated treatment to address this dire situation.’”
