Eligibility
Key inclusion criteria
* Male or female, = 18 years of age (19 years or older in South Korea, 20 years or older in Japan).
* Current diagnosis of MAC lung infection. MAC or mixed infection with MAC as the dominant species is allowed, with MAC as the intended organism for treatment.
* A chest computerized tomography (CT) scan, read locally, within 6 months prior to Screening to determine presence and size of pulmonary cavities. Participants who do not have a chest CT scan within 6 months prior to Screening will be required to obtain a chest CT scan, read locally, during Screening.
* Willingness and ability to adhere to prescribed study treatment during the study.
* Women of childbearing potential (WOCBP) (ie, fertile following menarche and until becoming postmenopausal unless permanently sterile) and fertile men (ie, all men after puberty unless permanently sterile by bilateral orchidectomy) agree to practice a highly effective method of birth control from Day 1 to at least 90 days after the last dose. Examples of such birth controls are:

* true abstinence (refraining from heterosexual intercourse during the entire study),
* copper intrauterine device (IUD),
* hormonal methods (levonorgestrel-releasing intrauterine system, progestogen implant, combined oral contraceptive pill [combined with barrier method]),
* exclusive homosexual relationship, or
* sole male partner who has undergone surgical sterilization with confirmation of azoospermia at least 3 months post procedure.
* Provide signed informed consent prior to administration of study drugs or performing any study-related procedure.
* Be able to comply with study drugs use, study visits, and study procedures as defined by the protocol.
* Men with partners who are WOCBP (pregnant or non-pregnant) agree to use condoms and non-pregnant partners should practice a highly effective method of birth control
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* Diagnosis of cystic fibrosis (CF).
* History of more than 3 MAC lung infections (a 4th MAC lung infection is not eligible)
* Received any mycobacterial antibiotic treatment for current MAC lung infection
* 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
* Relapse of prior MAC lung infection, defined as positive sputum culture for MAC =6 months of cessation of prior successful treatment
* Evidence of any pulmonary cavity = 2 cm in diameter, as determined by chest CT scan, read locally, during Screening or within 6 months prior to Screening
* Radiographic finding of new lobar consolidation, atelectasis, significant pleural effusion, or pneumothorax during routine clinical care within 2 months prior to Screening
* Active pulmonary malignancy (primary or metastatic) or any malignancy requiring chemotherapy or radiation therapy within 1 year prior to Screening or anticipated during the study
* Acute pulmonary exacerbation (eg, chronic obstructive pulmonary disease (COPD) or bronchiectasis) requiring treatment with antibiotics, or corticosteroids (intravenous [IV] or oral), within 4 weeks prior to and during Screening
* Current smoker
* History of lung transplantation
* Prior exposure to ALIS (including clinical study)
* Known hypersensitivity or contraindications to use to ALIS, aminoglycosides, or any of their excipients
* Disseminated MAC infection
* Administration of any investigational drug within 8 weeks prior to Screening
* Known or suspected acquired immunodeficiency syndromes (Human Immunodeficiency Virus (HIV) -positive, regardless of CD4 counts). Other immunodeficiency syndromes that may interfere with study participation in the opinion of the Investigator
* Current alcohol, medication, or illicit drug abuse
* Known and active COVID-19 infection
* Known hypersensitivity or contraindications to use of ethambutol, azithromycin (including other macrolides or ketolides), or any of their excipients per local labeling guidance.
