The primary aim of the study is to characterize the overall effect of CSL787 as well as the dose response of 2 active treatment regimens of inhaled CSL787 administered to participants with NCFB toward prolonging the TTF exacerbation.

Time to first (TTF) Exacerbation Timeframe: Up to Month 12 TTF exacerbation, where an exacerbation is defined as a deterioration in \\>= 3 of the following symptoms for \\>= 48 hours: cough; sputum volume and / or consistency; sputum purulence; breathlessness and / or exercise tolerance; fatigue and / or malaise; hemoptysis AND a clinician determines that antibiotic therapy is required. ### Secondary outcomes 1. Annualized Exacerbation Rate (AER) (Exacerbation Event Rate Per-participant Year) Timeframe: Up to Month 12 2. Number of Participants Achieving a Clinically Important Difference in the Quality of Life-Bronchiectasis (QoL-B) Respiratory Symptoms Scale Timeframe: Up to Month 12 The QoL-B questionnaire is a self-administered measure assessing symptoms, functioning, and health-related quality of life for patients with NCFB. This questionnaire contains 37 items on 8 different scales (Respiratory symptoms, Physical, Role, Emotional and Social Functioning, Vitality, Health Perceptions, and Treatment Burden). For each scale, scores are standardized on a 0-to-100-point scale; higher scores indicate better health-related quality of life. 3. Percentage of Participants Achieving a Clinically Important Difference in the QoL-B Respiratory Symptoms Scale Timeframe: Up to Month 12 The QoL-B questionnaire is a self-administered measure assessing symptoms, functioning, and health-related quality of life for patients with NCFB. This questionnaire contains 37 items on 8 different scales (Respiratory symptoms, Physical, Role, Emotional and Social Functioning, Vitality, Health Perceptions, and Treatment Burden). For each scale, scores are standardized on a 0-to-100-point scale; higher scores indicate better health-related quality of life. 4. Change From Baseline in QoL-B Respiratory Symptoms Scale Timeframe: From Baseline to Months 6 and 12 The QoL-B questionnaire is a self-administered measure assessing symptoms, functioning, and health-related quality of life for patients with NCFB. This questionnaire contains 37 items on 8 different scales (Respiratory symptoms, Physical, Role, Emotional and Social Functioning, Vitality, Health Perceptions, and Treatment Burden). For each scale, scores are standardized on a 0-to-100-point scale; higher scores indicate better health-related quality of life. 5. Change From Baseline in Total Colony-forming Unit (CFUs) for Pathogenic Bacteria Isolated from Sputum Timeframe: From Baseline to Month 1 6. Number of Participants with Treatment-emergent Adverse events (TEAEs) and Serious Adverse Events (SAEs) Timeframe: Up to Month 13 7.

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.
