This Phase 1/2 study by Boehringer Ingelheim monitors the long-term health of people with cystic fibrosis who took part in a previous study with the medicine BI 3720931; no additional BI 3720931 treatment is given here. Participants who previously received BI 3720931 stay in the study for 15 years with about 20 site visits (every 3 months for the first 2 years, then yearly), while those who received placebo stop once their group assignment is disclosed. At each visit doctors check participants' health, record any problems that could be related to BI 3720931, and perform lung function testing.
