A Study to Test Whether Different Doses of BI 1291583 Help People With Bronchiectasis

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT05238675

Brief Summary:

This study is open to adults with bronchiectasis. People can join the study if they produce sputum and have a history of 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 4 groups randomly, which means by chance. Participants in groups 1, 2, and 3 get different doses of BI 1291583. Participants in group 4 get placebo. Placebo tablets look like BI 1291583 tablets, but do not contain any medicine. Participants take the tablets once a day.

Participants are in the study for between 6 months and 1 year. During this time, they visit the study site about 10 times and get about 5 phone calls from the site staff.

The doctors document when participants experience flare-ups during the study. The time to the first flare-ups is compared between the treatment groups. Doctors also regularly check participants' health and take note of any unwanted effects.

Layout table for eligibility information
Ages Eligible for Study:   18 Years to 85 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

- Male or female patients: Women of childbearing potential (WOCBP) must be ready and able to use highly effective methods of birth control per ICH M3 (R2) that result in a low failure rate of less than 1% per year when used consistently and correctly, as well as one barrier method. A list of contraception methods meeting these criteria is provided in the patient information.

Men participating in this clinical trial must use male contraception (condom or sexual abstinence) if their sexual partner is a WOCBP.

  • Signed and dated written informed consent prior to admission to the study, in accordance with Good Clinical Practice (GCP) and local legislation.
  • Age of patients when signing the informed consent ≥18 (for Korea: ≥19) and ≤85 years.
  • Clinical history consistent with bronchiectasis (e.g., cough, chronic sputum production and/or recurrent respiratory infections) and investigator confirmed diagnosis of bronchiectasis by computed tomography (CT) scan. Subjects whose past chest radiographic image records are not available will undergo a chest CT scan during Screening. Historical scans must not be older than 5 years.
  • History of pulmonary exacerbations requiring antibiotic treatment. In the 12 months before Visit 1, patients must have had either:

    • at least 2 exacerbations, or
    • at least 1 exacerbation and a St. George´s Respiratory Questionnaire (SGRQ) Symptoms score of >40 at screening visit 1.

For patients on stable oral or inhaled antibiotics as chronic treatment for bronchiectasis, at least one exacerbation must have occurred since initiation of stable antibiotics.

- Current sputum producers with a history of chronic expectoration who are able to provide a spontaneous (not induced) sputum sample at Screening Visit 1.

Exclusion Criteria:

Laboratory and medical examination

  • Aspartate Aminotransferase (AST) and / or Alanine Aminotransferase (ALT) >3.0 x upper limit of normal (ULN) at Visit 1, or moderate or severe liver disease (defined by Child-Pugh score B or C hepatic impairment).
  • Estimated glomerular filtration rate (eGFR) according to Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula < 30 mL/min at Visit 1.
  • An absolute blood neutrophil count <1,000/mm^3 at Visit 1 (equivalent to <1,000 cells/µL or <109 cells/L).
  • Any findings in the medical examination and/or laboratory value assessed at Screening Visit 1 or during screening period, that in the opinion of the investigator may put the patient at risk by participating in the trial.
  • Positive serological tests for hepatitis B, hepatitis C, or human immunodeficiency virus (HIV) infection, or known infection status.

Concomitant diagnosis and therapy

  • A current diagnosis of:

    • Cystic Fibrosis

    • Reactive arthritis (Reiter's syndrome); keratoderma blennorrhagicum
    • Pityriasis rubra pilaris

  • Any clinically relevant (at the discretion of the investigator) acute respiratory infection within 4 weeks prior Visit 2, or any other acute infection requiring systemic or inhaled anti-infective therapy within 4 weeks prior Visit 2.
  • Any evidence of a concomitant disease, such as Papillon-Lefevre Syndrome, relevant pulmonary, gastrointestinal, hepatic, renal, cardiovascular, metabolic, immunological, hormonal disorders, or patients who are immunocompromised with a higher risk of invasive pneumococcal disease or other invasive opportunistic infections (such as histoplasmosis, listeriosis, coccidioidomycosis, pneumocystosis), that in the opinion of the investigator, may put the patient at risk by participating in the study.
  • Received any live attenuated vaccine within 4 weeks prior to Visit 2.
  • Medical conditions associated with periodontal disease (to be evaluated by a periodontist or dentist):

    • Any tooth that can potentially cause pain or infection as noted in the oral exam unless they are corrected before the study (e.g. pulp necrosis).
