First seen Sep 30, 2025 · Last updated Jun 14, 2026 · Updated 43 times

Summary

This study tests whether metformin, a standard diabetes medicine, can improve airway cell function in adults with cystic fibrosis-related diabetes (CFRD). About 30 participants who are already taking CF modulator drugs will take metformin and have their nasal cells tested. The goal is to see if metformin can help the lungs work better, not to cure CF or CFRD.
