New inhaled drug aims to keep bronchiectasis patients Flare-Up free
NCT ID NCT07048262
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests an inhaled medicine called CSL787 in adults with non-cystic fibrosis bronchiectasis, a lung condition that causes frequent infections and breathing problems. The goal is to see if CSL787 can delay the time until a person's next lung flare-up (exacerbation) compared to a placebo. About 450 adults aged 18 to 85 will take part, receiving either one of two doses of CSL787 or a placebo via a nebulizer for up to 12 months.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adult between the ages of 18 to 85 years * Primary diagnosis of NCFB confirmed by chest computed tomography (CT) scan, where bronchiectasis has been documented by a radiologist. Diagnosis in the medical records based on historical scans is acceptable if the chest CT scan confirming the participant's NCFB diagnosis was performed within 12 months before enrollment. Participants for whom no chest CT scan results are available within the previous 12 months will undergo a chest CT scan during the Screening Period * Exacerbation history within the previous 1 year defined as either 1 of the following: * \>= 2 documented exacerbations requiring oral and/or intravenous (IV) antibiotic therapy to treat a pulmonary infection. OR * 1 documented exacerbation requiring oral and/or IV antibiotic therapy to treat a pulmonary infection and a St. George's Respiratory Questionnaire (SGRQ) Symptoms score of \> 40 at Screening. * Note: Other medications to treat NCFB such as: oral macrolides, or dipeptidyl peptidase-1 (DPP-1) inhibitors are allowed, provided \>= 1 historical exacerbation occurred while on the medication for \>= 3 months at a stable dose. * Postbronchodilator percentage of the predicted normal forced expiratory volume in 1 second of expiration \[FEV1% predicted\] \> 35% and forced expiratory volume in 1 second (FEV1) \>= 1 liter (L) obtained in accordance with American Thoracic Society (ATS) / European Respiratory Society (ERS) standards for spirometry during Screening and at Baseline. Exclusion Criteria: * History of bronchospasm in response to inhaled therapies including inhaled antibiotics * Known or suspected hypersensitivity, or other severe reactions, to the investigational product (IP), to any excipients of the IP, or to other immunoglobulin. * Primary diagnosis of other pulmonary disorders, including chronic obstructive pulmonary disease (COPD) asthma or, diffuse panbronchiolitis (DPB), as determined by the investigator. * Pulmonary exacerbation requiring antibiotic therapy within the 4 weeks before Baseline.
