A Study to Learn How Well People With Bronchiectasis Tolerate Continued Treatment With Verducatib After Earlier Studies (AIRTIVITY®-ON)

Inclusion criteria: 1. Participants (adults and adolescents ≥12 years of age) who completed the treatment period in trials 1397-0014 or 1397-0017 as planned per protocol and did not discontinue trial treatment prematurely. 2. Male or female participants. Women of childbearing potential (WOCBP) must be ready and able to use highly effective methods of birth control per International Council of Harmonisation (ICH) M3 (R2) that result in a low failure rate of less than 1% per year when used consistently and correctly. A list of contraception methods meeting these criteria is provided in the participant information. 3. Signed and dated written informed consent and assent, if applicable, prior to admission to the trial, in accordance with Good Clinical Practice (GCP) and local legislation. Exclusion criteria: 1. Moderate or severe liver disease (defined by Child-Pugh score B or C hepatic impairment), unless the investigator determines it is in the best interest of the participant to enrol in the trial. 2. Estimated glomerular filtration rate (eGFR) according to Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula (adults) and Chronic Kidney Disease Under 25 (CKiD-U25) (adolescents) \<30 mL/min at Visit 1 (or at the last safety assessment in the parent trial, if no more than 6 weeks passed since then), unless the investigator determines it is in the best interest of the participant to enrol in the trial. 3. An absolute blood neutrophil count \<1000/mm\^3 (equivalent to \<1000 cells/µL or \<10\^9 cells/L) at Visit 1 (or at the last safety assessment in the parent trial, if no more than 6 weeks passed since then). 4. Any findings in the medical examination and/or laboratory value assessed at Visit 1 (or at the last safety assessment in the parent trial, concerning the laboratory tests, if no more than 6 weeks passed since then), that in the opinion of the investigator may put the participant at risk by participating in the trial. 5. Diagnosis of primary or secondary immunodeficiency made after end of treatment in preceding trial. 6. Any relevant pulmonary, gastrointestinal, hepatic, renal, cardiovascular, metabolic, immunological, hormonal, or other disorder that, in the opinion of the investigator, may put the participant at risk by participating in the study. 7. Participants who must or wish to continue the intake of restricted medications or any drug considered likely to interfere with the safe conduct of the trial. 8. Participants not expected to comply with the protocol requirements or not expected to complete the trial as scheduled, i.e. chronic alcohol or drug abuse or any other condition that, in the investigator's opinion, makes the participant an unreliable trial participant. Further exclusion criteria apply.
