New TB cocktail aims to shorten treatment
NCT ID NCT07672405
First seen Jun 27, 2026 · Last updated Aug 20, 2026 · Updated 8 times
Summary
This study tests a new combination of three drugs—sorfequiline, pretomanid, and linezolid—in 100 adults with newly diagnosed, drug-sensitive tuberculosis. Participants take the pills daily for 17 weeks. The goal is to see if the combo is safe and can clear the infection faster than standard care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- sorfequiline, pretomanid, and linezolid
- What this could lead to
- If successful, this could lead to a shorter, simpler treatment regimen for drug-sensitive tuberculosis, potentially reducing side effects and improving cure rates.
- What could go wrong
- This is an early phase 2b trial with only 100 participants, so results may not apply to everyone. The drugs can cause side effects like nerve damage or vision problems, and the regimen may not work better than current treatments.
