Summary
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.
Who is the study for?
Adults over 18 with cystic fibrosis not treated with CFTR therapy can join. They should have mild to moderate lung disease, be able to produce sputum daily, and have an FEV1 ≥40% of predicted. Participants need a negative COVID-19 test before testing, must not smoke or have quit for at least a year, and females must use strict birth control.
What is being tested?
The trial is studying the effect of Losartan on mucociliary clearance in cystic fibrosis patients ineligible for CFTR therapies. It's a small-scale proof of concept study designed to understand how this medication might help clear mucus from the lungs.
What are the potential side effects?
Losartan may cause dizziness due to low blood pressure, increased potassium levels which can affect heart rhythm, kidney function changes, or allergic reactions if there's intolerance to ARBs (angiotensin receptor blockers).

Other Research
Common treatments for Cystic Fibrosis (CF) target various aspects of the disease. Antibiotics are used to manage pulmonary infections, reducing bacterial load and inflammation.
Azithromycin, a macrolide antibiotic, not only fights infections but also has anti-inflammatory properties, which help in reducing lung damage. Hypertonic saline improves mucociliary clearance, aiding in the removal of thick mucus from the airways.
Gene therapy aims to correct the underlying genetic defect by introducing functional CFTR genes into the affected cells. Losartan, an Angiotensin II Receptor Blocker, is being studied for its potential to improve mucociliary clearance, which could offer an additional therapeutic avenue for CF patients.
These treatments are crucial as they address both the symptoms and the root causes of CF, improving quality of life and potentially extending lifespan.
