Central reading confirmation, where images are evaluated by independent centralized experts, is required before the participant is randomized * Participant with a history of chronic expectoration who are current sputum producers and are able to provide spontaneous sputum sample at Screening. If the participant is unable to produce spontaneous sputum at Screening, the participant will be considered a screening failure and may be rescreened once * Participant with a history of at least 2 moderate or severe pulmonary exacerbations within the past 12 months prior to Screening or 1 severe pulmonary exacerbation within 6 months prior to Screening * Participant with post- Bronchodilator (BD) forced expiratory volume (FEV) 1% predicted ≥30% at Screening and Baseline * Participant has acceptable inhaler (where applicable) and spirometry techniques according to American Thoracic…
