A Study to Test How Well BI 1291583 is Tolerated by People With Cystic Fibrosis Bronchiectasis (Clairafly™)
United States, Belgium, France22 participantsStarted 2024-04-05
Plain-language summary
This study is open to adults aged 18 years and older with cystic fibrosis bronchiectasis.
The purpose of this study is to find out whether a medicine called BI 1291583 is tolerated by people with cystic fibrosis bronchiectasis. Participants are put randomly into 2 groups. One group takes BI 1291583 tablets and the other group takes placebo tablets. Placebo tablets look like BI 1291583 tablets but do not contain any medicine. Participants in both groups take 1 tablet once a day for 12 weeks. Participants have twice the chance of being placed in the BI 1291583 group than in the placebo group.
Participants are in the study for about 6 months. During this time, they visit the study site 7 times. At the visits, the doctors check the health of the participants and note any health problems that could have been caused by BI 1291583.

Inclusion criteria
. Age of patients when signing the informed consent ≥18 years
. Historical clinical diagnosis of Cystic fibrosis (CF) (symptoms of CF and sweat chloride ≥ 60 mmol/L and/or 2 CF-causing Cystic fibrosis transmembrane conductance regulator (CFTR) mutations)
. Investigator-confirmed diagnosis of Bronchiectasis (BE) by Computed tomography (CT) scan and clinical history consistent with BE (e.g., cough, chronic sputum production, recurrent respiratory infections). Subjects whose past chest CT 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 an 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 BE, at least one exacerbation must have occurred while on stable antibiotics.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Occurrence of Any Treatment Emergent Adverse Events
Timeframe: From first dose of trial drug administration until last dose of trial drug administration plus 28 days of residual effect period, up to 16 weeks.
. Patients must be able to provide spontaneous or induced sputum samples. Further inclusion criteria apply.
Exclusion criteria
. Moderate or severe liver disease (defined by Child-Pugh score B or C hepatic impairment) or Aspartate aminotransferase (AST) and/or Alanine aminotransferase (ALT) \> 3.0x Upper limit of normal (ULN) at Visit 1
. Estimated glomerular filtration rate (eGFR) according to Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula \< 30 mL/min at Visit 1
. Absolute blood neutrophil count \< 1,000/mm\^3 (equivalent to \< 1000 cells/μL or \< 10\^9 cells/L) at Visit 1
. Any findings in the medical examination (including blood pressure (BP), pulse rate (PR), or electrocardiogram (ECG)) and/or laboratory value assessed at 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 (also confirmed with Hepatitis C virus ribonucleic acid (HCV RNA)), or human immunodeficiency virus (HIV) infection, or known infection status.
