This study is open to adults with non-cystic fibrosis bronchiectasis. The main purpose of this study is to find out how a medicine called BI 1323495 is tolerated by people with non-cystic bronchiectasis.

The study tests 2 different doses of BI 1323495. Some of the participants get placebo. It is decided by chance who gets BI 1323495 and who gets placebo. Participants take BI 1323495 or placebo as tablets twice a day for 3 months. Placebo tablets look like BI 1323495 tablets but do not contain any medicine. Participants can also continue taking standard medicines for noncystic bronchiectasis throughout the study.

Participants are in the study for about 4 months. During this time, the participants visit the study site about 11 times and get about 2 phone calls. At the visits, doctors check the health of the participants and note any health problems that could have been caused by BI 1323495.

\--For 'female not of childbearing potential' at least one of the following
criteria must be fulfilled
Permanently sterile (permanent sterilisation methods include hysterectomy, bilateral salpingectomy, and bilateral oophorectomy; tubal ligation is not a method of permanent sterilisation)
Postmenopausal, defined as at least 1 year of spontaneous amenorrhea without an alternative medical cause (in questionable cases a blood sample with Follicle Stimulating Hormone (FSH) above 40 U/L and estradiol below 30 ng/L is confirmatory)
Men must be vasectomised with documented absence of sperm or use male contraception (condom or sexual abstinence) from the first administration of trial medication until 30 days after the last administration of trial medication if their sexual partner is a woman of childbearing potential (WOCBP)
Clinical history consistent with non cystic fibrosis bronchiectasis (nCFB) (cough, chronic sputum production and/or recurrent respiratory infections) and proven and documented diagnosis of bronchiectasis by computed tomography (CT) scan including dilated airways compatible with bronchiectasis at initial diagnosis. Bronchiectasis of various etiologies will be allowed, with exclusion criteria as below
Vaccination against Streptococcus pneumoniae in accordance with national vaccination recommendations
Signed and dated written informed consent prior to admission to the study, in accordance with Good Clinical Practice (GCP) and local legislation
FEV1 30 % predicted (post-bronchodilator) at Screening Visit 1
Stable (i.e., no dose change) regimen of standard nCFB treatment (including - but not limited to - hypertonic inhalation solutions, mucolytics, Long Acting Muscarinic Agonists (LAMA)/ Long Acting Beta Agonists (LABA) / inhaled corticosteriods (iCS), oral antibiotic maintenance regimen, and physiotherapy), if applicable, administered at least for 4 weeks prior to Screening Visit 1 and throughout the run-in period
Regular daily sputum producers with a history of chronic expectoration who are able to provide a typical bronchiectasis sputum sample at Screening Visit 1
Sputum neutrophil elastase positive based on point of care test (NEATstik score 6) assessment at Visit 2a and Visit 2b
Subjects genotyped as UDP-Glucuronosyltransferase-2B17 (UGT2B17) extensive metabolizers prior to randomisation, i.e., carrying at least one functional allele of the UGT2B17 gene ( _1/_ 1 or _1/_ 2)

Exclusion Criteria

Any finding in the medical examination (including BP, pulse rate (PR), or ECG) and/or laboratory value and/or any evidence of a concomitant disease assessed as clinically relevant by the investigator
Concomitant diagnosis of pulmonary disease other than bronchiectasis, chronic obstructive pulmonary disease (COPD), or asthma
A current diagnosis of cystic fibrosis (CF), primary immunodeficiency, active Allergic Bronchopulmonary Aspergillosis (ABPA) (defined by receipt of corticosteroids, anti-fungal treatment or monoclonal antibody treatment), or alpha-1 antitrypsin (A1AT) deficiency as underlying disease
A history or current immunodeficiency or are currently being treated (or are planned to be treated) with immunomodulatory drugs (except for iCS or low-dose oral corticosteroids), including disease-modifying anti-rheumatic drugs (DMARDs), and/or Immunglobulin G (IgG) treatments. Other medication that is excluded will be provided in the investigator site file (ISF). On the day of the site visit with lung function measurement, no bronchodilators should be used until after completion of lung function assessment
Any acute infections defined as infections requiring antibiotic therapy, or Upper Respiratory Tract Infection (URTI). Are currently being treated (or are planned to be treated) for a nontuberculous mycobacterial (NTM) lung infection or tuberculosis
A history of invasive pneumococcal disease
Inhaled antibiotic treatment or cycling oral antibiotic treatment with changed dose regimen 4 weeks prior to Screening Visit 1
A treatment for a pulmonary exacerbation 4 weeks prior to Screening Visit 1
Laboratory confirmed severe acute respiratory syndrome (SARS)-coronavisurs (CoV)-2 infection (PCR positive) within 4 weeks prior to Screening Visit 1
Household contact with an individual with confirmed SARS-CoV-2 infection within 4 weeks prior to Screening Visit 1
