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).
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. The subject must have evidence supportive of a PCD diagnosis based on the following:
A. Subjects must be =18 years of age and must have bronchiectasis on historical chest imaging
B. All subjects must ALSO have documentation of at least 1 of the following historical tests:
? For patients with no laterality defect, nNO level, measured with a chemiluminescent NO analyzer, during plateau <77 nL/min on 2 occasions, at least 2 months apart, with CF excluded by sweat chloride or genetic testing
? For patients with a laterality defect, nNO level, measured with a chemiluminescent NO analyzer, during plateau <77 nL/min on at least 1 occasion
? Diagnostic ciliary ultrastructural defect on transmission electron micrograph (TEM).
? 2 loss of function and/or known mutations in a single PCD-associated gene.
Prior to randomization, all subjects must have a confirmed diagnosis of PCD (including central review, as required) based on 1 of the following:
? 2 loss of function and/or known mutations in a single PCD-associated gene identified by the designated central genetic testing laboratory from the specimen obtained at the Screening Visit; previous genotype results cannot be used to confirm eligibility for randomization
? Diagnostic ciliary ultrastructural defect on transmission electron micrograph. A previously prepared TEM specimen will be reviewed centrally as defined in the Study Reference Manual; a new specimen does not need to be obtained
? Laterality defect that includes dextrocardia plus bronchiectasis in more than 1 lobe on historical chest imaging
5. Subjects with ppFEV1 of =40 to <90 percentage points adjusted for age, sex, and height according to the Global Lung Function Initiative (GLI) predicted values 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 2 alternating 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
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
b. Abnormal nasal potential difference (NPD) test
c. 2 CF-causing 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.
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 and long-acting bronchodilator use the night before the first and last clinic visit of each treatment period.
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/coagulation 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. Use of 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 28 days before Day 1 (topical otic antibiotics allowed).
10. History of significant intolerance to inhaled HS, as determined by the investigator.
11. History of drug or alcohol abuse, in the opinion of the investigator.
12. Known hypersensitivity to any of the study drugs or amiloride.
13. Used ivacaftor within 28 days prior to Day 1 or anticipate need for ivacaftor during the study.
14. Pregnant and/or nursing females.
15. Any clinically significant laboratory abnormalities at the Screening Visit as judged by the investigator, or any of the following:
a. Plasma or serum potassium > upper limit of normal (ULN)
b. Abnormal renal function, defined as creatinine clearance rate <50 mL/min using the Cockcroft-Gault equation
c. Abnormal liver function, defined as =3 × ULN for alanine aminotransferase (ALT), aspartate aminotransferase (AST), or total bilirubin, unless accounted for by Gilbert’s syndrome (benign indirect hyperbilirubinemia)
d. Hemoglobin concentration <10.0 g/dL
16. Unwilling or unable to follow the contraception guidelines as outlined in Section 11.6.5.1.
17. History of at least 2 sputum or throat swab cultures yielding B. cepacia complex or M. abscessus or M. avium within the previous 2 years.
18. Has had surgery within 3 months of Day 1 that required general anesthesia and hospitalization.
