Nebulized CSL787 (inhaled IgG) to reduce lung flare-ups in adults with non-cystic fibrosis bronchiectasis
Official title: A Phase 2b, Multicenter, Randomized, Double-blind, Parallel-group, Placebo-controlled, Dose Range Finding Study to Evaluate the Efficacy, Safety, and Tolerability of Nebulized CSL787 in Adults (18 to 85 Years) With Non-cystic Fibrosis Bronchiectasis
Run by CSL Behring · NCT07048262 · Data updated 2026-11-12
This research will test whether inhaled CSL787 (a nebulized immunoglobulin medicine) can delay or reduce lung flare-ups in adults with non-cystic fibrosis bronchiectasis over 6–12 months compared with placebo.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18–85 with non-cystic fibrosis bronchiectasis confirmed by chest CT and a documented exacerbation history in the prior year (either ≥2 antibiotic-treated exacerbations, or 1 antibiotic-treated exacerbation plus an SGRQ Symptoms score >40) who can use a nebulizer are ideal candidates.
✕Probably not a fit
People without a recent history of exacerbations, those with cystic fibrosis, or patients already on chronic systemic immunoglobulin therapy or with contraindications to inhaled therapies are unlikely to benefit from this intervention.

What this trial studies
This is a phase 2b, multicenter, randomized, double-blind, placebo-controlled, parallel-group dose-ranging study comparing two active dosing regimens of nebulized CSL787 versus placebo over 6 to 12 months. Adults with non-cystic fibrosis bronchiectasis confirmed by chest CT and with a recent history of exacerbations are eligible. Participants will inhale CSL787 or placebo via a nebulizer on a scheduled regimen while investigators record time to first pulmonary exacerbation, safety, and tolerability. The trial is designed to characterize dose response and the overall effect of inhaled CSL787 on prolonging time to first exacerbation.
Why it matters
Potential benefit: If successful, inhaled CSL787 could reduce the frequency or delay the onset of pulmonary exacerbations and lower the need for antibiotic treatments in people with non-CF bronchiectasis.
How similar studies have gone: Using inhaled immunoglobulin for bronchiectasis is a relatively novel approach and there are limited prior clinical data showing definitive success in this population.

Inclusion Criteria: * Adult between the ages of 18 to 85 years * Capable of spontaneous sputum production at Screening. * 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 documented 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 one of the following: * greater than or equal (≥) 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 greater than (\>) 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 percent predicted forced expiratory volume in 1 second (FEV1%) \> 35% and forced expiratory volume in 1 second (FEV1) ≥ 1 L obtained in accordance with American Thoracic Society (ATS) / European Respiratory Society (ERS) standards for spirometry during Screening and at Baseline on Day 1. Exclusion Criteria: * History of severe or uncontrolled asthma, or 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 immunoglobulins. * Primary diagnosis of other pulmonary disorders, including chronic obstructive pulmonary disease (COPD), asthma, or diffuse panbronchiolitis (DPB), as determined by the investigator. * Use of oral, IV, or inhaled antibiotic therapy to treat a pulmonary exacerbation or any other condition within 4 weeks before Baseline measurements on Day 1.
