Bronchiectasis clinical trials at UC Davis

This study is open to adults and adolescents aged 12 to under 18 with bronchiectasis. People can participate in this study if they produce sputum and have had flare-ups (also called exacerbations). The purpose of this study is to find out whether a medicine called BI 1291583 helps people with bronchiectasis. Participants are put into 2 groups randomly, which means by chance. One group takes BI 1291583 tablets and the other group takes placebo tablets. A placebo tablet looks like the BI 1291583 tablet but does not contain any medicine. Participants take 1 tablet once a day for up to 1 year and 6 months. Participants are in the study for up to 1 year and 8 months. During this time, participants visit the study site up to 10 times and get about 13 phone calls from the site staff. Participants regularly complete a diary on a smartphone about their bronchiectasis symptoms and study doctors regularly check for any changes. The study doctors document when participants experience flare-ups. The number of flare-ups is compared between the participants who receive BI 1291583 and those who receive the placebo. The study doctors also regularly check participants' health and take note of any unwanted effects.

This study is for adults and adolescents who are at least 12 years old and have bronchiectasis. People can participate if they completed a previous study with the study medicine called verducatib. The purpose of this study is to find out how well verducatib is tolerated when people with bronchiectasis take it for a long time. The study also looks at breathing problems, how often lung flare-ups happen, and how quickly lung function changes. This is a roll-over study for participants who completed a previous study with verducatib: AIRTIVITY® (1397-0014) or CLAIRLEAF® (1397-0017). All participants receive verducatib. Participants take verducatib as tablets once a day at home. They may continue their usual treatment for bronchiectasis during the study. Participants can stay in the study for up to 1 year and 9 months. Treatment with verducatib can continue for up to 1 year and 6 months. About 6 study visits are done at the study site and about 4 are done by phone. At all visits, the doctors check participants' health and collect information on any health problems that occur during the study. The doctors also look at lung flare-ups and measure lung function over time.
