New drug combo takes on rare, Drug-Resistant lung bug
NCT ID NCT07485010
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This trial tests a new combination of antibiotics (called Arm D) against standard treatments for a rare lung infection caused by Mycobacterium abscessus. About 300 people with or without cystic fibrosis will take part. The goal is to see if the new combo clears the infection better and with fewer side effects over a shorter treatment period.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- sulbactam-durlobactam plus ceftriaxone, amoxicillin, azithromycin, and clofazimine
- What this could lead to
- If it works, this could point toward a more effective treatment for a hard-to-treat lung infection, potentially reducing treatment duration and side effects.
- What could go wrong
- This is an early phase 2 trial with only 300 participants, so results may not apply to everyone. The new combination may not clear the infection better than current treatments and could cause unexpected side effects.
