NCT ID NCT05838183
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at people with interstitial lung disease (ILD) and obstructive sleep apnea (OSA) to learn more about these conditions. Researchers will collect medical data, lung samples, and sleep test results from 70 participants. The goal is to find better ways to diagnose and understand these diseases, not to test a new treatment.
