New drug cocktail shows promise against Drug-Resistant TB
NCT ID NCT02333799
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested a combination of three drugs—bedaquiline, pretomanid, and linezolid—in 109 people with extensively drug-resistant TB (XDR-TB) or multi-drug resistant TB (MDR-TB) that didn't respond to other treatments. Participants took the drugs for 6 to 9 months. The goal was to see if the combo could clear the infection and prevent it from coming back. Results from this completed phase 3 trial help show whether this shorter, all-oral regimen is a safe and effective option for tough TB cases.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
a combination of three drugs: bedaquiline, pretomanid (PA-824), and linezolid
What this could lead to
If successful, this could provide a shorter, more effective treatment option for people with highly drug-resistant tuberculosis, potentially replacing longer and more toxic regimens.
What could go wrong
This is a completed phase 3 trial with 109 participants, so results are more reliable than earlier studies. However, the combination may still cause side effects like nerve damage or bone marrow suppression from linezolid, and it may not work for all TB strains.
