  • Additional Exclusion Criteria for Participants with NCFB in Cohort 3
• COPD exacerbation within 28 days prior to screening or that has not returned to baseline

Más betegség

• Acute respiratory infection within 28 days of screening
• Known immunodeficiency that, in the investigator's judgment, is clinically significant and places the individual at a substantially elevated risk for opportunistic infections.
• Known history of a clinically significant abnormal electrocardiogram (ECG), or presence of an abnormal ECG that is deemed clinically significant by the investigator
• Bronchiectasis primarily due to cystic fibrosis, primary ciliary dyskinesia, non-tuberculous mycobacterial infection, chronic aspiration, or predominantly traction bronchiectasis due to interstitial lung disease (ILD), in the investigator's judgment
• Diagnosis of asthma, that in the investigator's judgment, is the primary driver of the individual's respiratory disease (e.g., primary asthma with incidental bronchiectasis findings)
• Diagnosis of COPD that, in the investigator's judgment, is the primary driver of the individual's respiratory disease (e.g., primary COPD with incidental bronchiectasis findings)
  • Additional Exclusion Criteria for Participants With COPD (Cohort 1, Cohort 2, and Cohort 4):
• Asthma/COPD overlap syndrome

Laborértékek

• Any medical condition or abnormal clinical laboratory finding that, in the investigator's judgment, would preclude the individual's safe participation in and completion of the study or could affect the interpretation of the results
• QT interval corrected through use of Fridericia's formula (QTcF) >450 milliseconds (ms) for males or >470 ms for females
  • Additional Exclusion Criteria for Participants in Part B -More than 2 chest CTs or other procedures known to expose the lungs to greater than 100 millisievert (mSv) within 12 months prior to screening
  • Additional Exclusion Criteria for Participants With NCFB (Cohort 1, Cohort 2, and Cohort 3)

Egyéb

• Pregnant or breastfeeding, or intention of becoming pregnant during the study or within the timeframe in which contraception is required
• Known significant bronchodilator response of >10% predicted change in FEV1 or FVC, in the investigator's judgment
• Poor peripheral venous access

• Percent predicted FEV1 ≥ 40% by spirometry during screening

• Stable disease for ≥ 28 days prior to screening and through to initiation of study treatment
  • Additional Inclusion Criteria for Participants in Part B
• Chronic sputum production of ≥1 teaspoon per day as reported in the sputum volume item
• Ability to produce a sputum sample that is suitable for central laboratory determination of mucus percent solids and sialic acid concentration exploratory biomarker research, and biomarker assay development
• Availability of a representative blood sample for exploratory biomarker research and biomarker assay development
  • Additional Inclusion Criteria for Participants With Non-cystic Fibrosis Bronchiectasis (NCFB) (Cohort 1, Cohort 2, and Cohort 3):
• Diagnosis of bronchiectasis on the basis of prior chest computed tomography (CT), involving at least 2 lobes, with at least one lobe of involvement in the right lung as assessed by the investigator
  • Additional Inclusion Criteria for Participants With Chronic Obstructive Pulmonary Disease (COPD) (Cohort 1, Cohort 2, and Cohort 4):
• COPD defined as post-bronchodilator FEV1/FVC ratio of <0.7
• Chronic bronchitis, with a definition including chronic cough and excessive sputum production for more than 3 months per year for at least 2 years prior to screening
• Former smoker with a minimum of 10 pack-year history (e.g., 20 cigarettes/day for 10 years) or non-smoker with at least one documented COPD risk factor
