This will be a study in the home care setting to further validate the concept of Simeox 200 in a cohort of patients with bronchiectasis and overproduction of mucous as an alternative to other methods of ACT(airway clearance techniques). Bronchiectasis is a chronic lung disease where airways become permanently damaged, widened, and lose their ability to clear mucus, leading to a buildup of bacteria, recurrent infections, and symptoms like a daily cough, thick, discolored phlegm, shortness of breath, and fatigue. The device is a 510(k) FDA cleared device that works using by air and vibration to help clear mucous from the lungs. There are 4 visits and an at home usage period. The study will be running approximately a year or until the cohort is filled. The data from this study will be used to power a future randomized controlled pivotal clinical study comparing Simeox 200 against other ACTs such as High Frequency Chest Wall Oscillation (HFCWO).

The purpose of the study is to learn more about an experimental drug called ORC-13661 that may be helpful in treating hearing loss due to antibiotic use. The study is researching whether the drug is safe and tolerable, and trying to find out whether the drug may be able to mitigate or prevent hearing loss in patients being treated with intravenous (IV) amikacin. Participation in the study will consist of up to 10 visits over up to 129 days. The Day 1 visit (following the screening visit) will last up to 8 hours, while other visits will last up to 5 hours Participants will be randomly assigned to receive either ORC-13661at a higher dose or a lower dose or a placebo (a pill that looks the same as the study drug but has no real medicine in it), for up to 90 days to be taken along with IV amikacin. Participants will be asked to have a number of tests and procedures, which include questionnaires about family, medical, and hearing history, physical and hearing examination, and assessments of hearing.
