Could a cystic fibrosis drug ease stubborn sinus infections?
NCT ID NCT03439865
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early study tests whether ivacaftor, a drug used for cystic fibrosis, can help people with chronic sinusitis caused by hard-to-treat bacteria. Twenty adults will receive either ivacaftor plus standard care or standard care alone for 14 days. Researchers will check safety, symptom scores, and infection markers.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Ivacaftor (Kalydeco)
What this could lead to
If it works, this could point toward a new treatment option for chronic sinus infections that don't respond to standard care.
What could go wrong
This is a very early, small pilot study with only 20 people. It may not show clear benefits, and ivacaftor is not yet proven for this condition.
