Refractory MAC lung infection, defined as having positive MAC cultures while being treated with a multidrug mycobacterial antibiotic treatment regimen for a minimum of 6 consecutive months and no documented successful treatment, defined as negative sputum culture for MAC and cessation of treatment
5. Relapse of prior MAC lung infection, defined as positive sputum culture for MAC ≤ 6 months of cessation of prior successful treatment
6. MAC isolate with MIC for liposomal amikacin ≥ 128 µg/mL at Screening
7. Evidence of any pulmonary cavity ≥ 2 cm in diameter, as determined by chest CT scan, read locally, within 6 months prior to Screening

20. Positive pregnancy test or lactation at Screening. All WOCBP will be tested. Women not of child-bearing potential are defined as postmenopausal (ie, amenorrheic for 12 months without an alternative medical cause), or naturally or surgically sterile through bilateral oophorectomy, hysterectomy, or bilateral salpingectomy. For women under the age of 45, confirmatory testing with follicle stimulating hormone should be considered.)
21. Administration of any investigational drug within 8 weeks prior to Screening
22. Acquired and primary immunodeficiency syndromes (eg, HIV-positive, regardless of CD4 counts)
23. Significant (as determined by the Investigator) hearing loss, vestibular dysfunction, neuromuscular weakness or a diagnosis of myasthenia gravis, where the potential risk of aminoglycoside toxicity outweighs the potential benefit
24. Aspartate aminotransferase or alanine aminotransferase ≥ 3 times the upper limit of normal (ULN) or total bilirubin ≥ 2 times ULN at Screening
25. Absolute neutrophil count ≤ 500/μL at Screening
26. Serum creatinine > 2 times ULN at Screening
27. Current alcohol, medication, or illicit drug abuse
28. Any condition that, in the opinion of the Investigator, interferes with ability to safely complete the study or adhere to study requirements |

E.5 End points |
E.5.1 | Primary end point(s) |
Findings on psychometric validation optimized and reported for:
1) Cross-sectional validation (modern psychometrics, internal consistency, concurrent validity, and known-groups validity) at Baseline.
2) Test-retest reliability between Screening and Baseline among subjects reporting no change on Patient Global Impression of Severity (PGI-S) between Screening and Baseline. PGI-S anchors will be PRO specific, with a respiratory and fatigue PGI-S applied to the Quality of Life – Bronchiectasis (QOL-B) respiratory domain and Patient-Reported Outcome Measurement Information System – Fatigue-Short Form 7a (PROMIS F-SF 7a), respectively.
3) Within-subject meaningful change estimated via anchor-based methods and validated via empirical cumulative distribution functions (eCDFs) and probability density functions (ePDFs) between Baseline and End of Study (EOS) (Month 7). |
