Trial Summary

What is the purpose of this trial?

This trial is testing losartan, a blood pressure medication, to see if it can help clear mucus from the lungs of cystic fibrosis patients who can't use current treatments. These patients need alternative treatments because they don't respond to existing options. Losartan may reduce lung inflammation, making it easier for them to breathe.
