- •Subjects who meet all of the following inclusion criteria will be eligible.
- •1. Subject (or subject’s legally appointed and authorized representative) will sign and date an informed consent form (ICF) and, where appropriate, assent form.
- •2. Willing and able to comply with scheduled visits, treatment plan, study restrictions laboratory tests, contraceptive guidelines, and other study procedures.
- •3. Willing and able to use the nebulization device as directed by the instructions for use.
- •4. Confirmed diagnosis of PCD based on the following:
- •A. Subjects =12 to <18 years of age must meet 2 or more of the following PCD clinical criteria:
- •¿ Unexplained neonatal respiratory distress (at term birth) with need for respiratory support with CPAP and/or oxygen for >24 hours
- •¿ Any organ laterality defect confirmed by chest imaging – situs inversustotalis, situs ambiguous, or heterotaxy
- •¿ Daily, year-round wet or productive cough starting in first year of life or bronchiectasis on chest imaging
- •¿ Daily, year-round nasal congestion starting in first year of life or pansinusitis on sinus imaging
- •B. Subjects =18 years of age must have bronchiectasis on chest imaging
- •C. All subjects must ALSO have at least one of the following confirmatory tests:
- •¿ For patients with no laterality defect, nNO level during plateau <77 nL/min on 2 occasions, >2 weeks apart, with CF excluded by sweat chloride or genetic testing
- •¿ For patients with a laterality defect, nNO level during plateau <77 nL/min on at least 1 occasion
- •¿ Diagnostic ciliary ultrastructural defect on transmission electron micrograph
- •¿ Two loss of function and/or known mutations in a single PCD-associated gene.
- •5. Subjects with percent predicted FEV1 of =40 to <90 percentage points adjusted for age, sex, and height according to the Global Lung Initiative (GLI) at the Screening Visit, taken 4 hours or more after last dose of short-acting bronchodilators (ß-agonists and/or
- •anticholinergics)
- •6. Non-smoker for the past 90 days prior to the Screening Visit and less than a 5 pack-year lifetime history of smoking, and willing to not smoke while enrolled in the study.
- •7. Stable regimen of medications and chest physiotherapy for the 28 days prior to Day 1, and no anticipated need for changes during the study period (other than stopping inhaled HS).
- •8. If currently using daily inhaled HS, must be able to discontinue its use for the duration of the study.
- •9. If taking daily chronic or chronic cycling antibiotics, has been on a consistent regimen for at least 4 months prior to the Screening Visit. The cycling regimen of antibiotics can be either intermittent monotherapy (e.g., 28 days on/28 days off) or continuous alternating
- •therapy (e.g., 28-day cycles of two antibiotics).
- •10. Clinically stable (as deemed by the investigator) for at least 14 days prior to the Screening Visit with no evidence of significant new or acute respiratory exacerbations, excluding symptoms of allergic (perennial or seasonal) or non-allergic rhinitis.
- •11. Female subjects of childbearing potential must have a negative serum pregnancy test at the Screening Visit. Females of childbearing potential must have a negative urine pregnancy test at the Day 1 and Day 57 visits before receiving the first dose of study drug in each Treatment Period, respectively. Subjects of childbearing potential and who are sexually active must meet the contraception requirements outlined in Section 11.6.5.1.

排除标准
- •Subjects who meet any of the following exclusion criteria will not be eligible.
- •1. Diagnosis of CF, including at least 1 of the following:
- •a. Documented sweat chloride test =60 mM by quantitative pilocarpine iontophoresis or
- •b. Abnormal nasal transepithelial potential difference (NPD) test or
- •c. 2 CF-causing genetic mutations in the CFTR gene
- •2. Subjects with only 1 mutation in the CFTR gene and a sweat chloride test =60 mM by quantitative pilocarpine iontophoresis.
- •3. History of any organ transplantation or lung resection or chest wall surgery of such severity that it has an impact on pulmonary function.
- •4. Significant congenital heart defects, other than a laterality defect, at the discretion of the investigator.
- •5. Diagnosis of Cri du chat syndrome (chromosome 5p deletion syndrome).
- •6. Inability to withhold short-acting bronchodilator use for 4 hours prior to clinic visit.
- •7. History of any illness or any clinical condition that, in the opinion of the investigator, might confound the results of the study or pose an additional risk in administering study drug(s) to the subject. This may include, but is not limited to history of clinically significant and uncontrolled adrenal, neurologic, gastrointestinal, renal, hepatic, cardiovascular (including hyper/hypotension and tachy/bradycardia), psychological, pulmonary (other than PCD), metabolic, endocrine, or hematological disorder or disease, or scoliosis of such severity that it impacts pulmonary function or any other major disorder or disease, in the opinion of the investigator.
- •8. Used diuretics (including amiloride) or renin-angiotensin antihypertensive drugs (e.g., spironolactone, angiotensin converting enzyme [ACE] and/or neural endopeptidase
- •(NEP)-inhibitors, or angiotensin receptor blockers [ARBs]) or trimethoprim or drospirenone in the 28 days before Day 1 or anticipate need for these medications during the study.
- •9. Had symptoms of acute upper or lower respiratory tract infection or had an acute pulmonary exacerbation requiring treatment or was treated with systemic antibiotics for ear or sinus disease within 14 days before Day 1 (topical otic antibiotics allowed).
- •10. History of significant intolerance to inhaled HS, or intolerance to the single dose of HS at the Screening Visit, as determined by the investigator.
- •11. History of drug or alcohol abuse, in the opinion of the investigator.
- •12. Known hypersensitivity to the study drug or amiloride.
- •13. Pregnant and/or nursing females.
- •14. Any clinically significant laboratory abnormalities at the Screening Visit as judged by the investigator, or any of the following:
- •a. Plasma or serum potassium > central laboratory vendor upper limit of normal (ULN)
- •b. Abnormal renal function, defined as creatinine clearance rate <60 mL/min using the Bedside Schwartz equation (for subjects 12 to17 years of age) or <50 mL/min using the Cockcroft-Gault equation (for subjects =18 years of age).
- •c. Abnormal liver function, defined as =3 × ULN for alanine transaminase (ALT), aspartate transaminase (AST), or > 2 x ULN for total bilirubin, unless accounted for by Gilbert’s syndrome (benign indirect hyperbilirubinemia)
