TB-PRACTECAL is the first-ever multi-country, randomised, controlled clinical trial to report on the efficacy and safety of a six-month, all-oral regimen for RR-TB. It tested a six-month regimen of bedaquiline, pretomanid, linezolid and moxifloxacin (BPaLM), against the locally accepted standard of care. The trial enrolled 552 patients overall, of which 301 were included in the analysis at this stage. The trial took place in seven sites across Belarus, South Africa and Uzbekistan.
The phase II/III clinical trial found that the new shorter treatment regimen was very effective against RR-TB. 89 per cent of patients in the BPaLM group were cured, compared to 52 per cent in the standard of care group. Tragically four patients died from TB or treatment side effects in the control group, while there were no deaths among patients on the new regimen. Additionally, trial results showed that the new drugs lead to a significantly lower rate of major side effects, with 80 per cent of patients avoiding any major side effects compared to 40 per cent in the control group.
