Criteria

Key Inclusion Criteria:

• Has a diagnosis of Nontuberculous Mycobacterial pulmonary disease caused by MABc

• Has at least 2 of the following NTM-infection symptoms present at Screening and Baseline: chronic cough, coughing up blood (hemoptysis), wheezing, chest pain, frequent throat clearing, phlegm or sputum production, shortness of breath, fatigue, fever, night sweats, poor appetite, and/or weight loss.

• At least 1 positive pulmonary (sputum) culture for MABc in the 6 months prior to Screening and 1 positive culture at Screening

• Radiographic evidence of MABc infection via computed tomography (CT) scan of the chest within 3 months prior to Screening

• In the opinion of the investigator, guideline-directed antibiotic therapy for treatment of MABc will not be required within the next 3 months, and a delay, in order for the subject to participate in a placebo-controlled clinical trial, is considered reasonable and clinically acceptable

• Additional inclusion criteria as per protocol

Key Exclusion Criteria:

• Radiologic evidence of cavitary disease

• Known active pulmonary tuberculosis

• Cystic fibrosis

• History of lung transplantation

• Another advanced lung disease with a known percent predicted forced expiratory volume in 1 second < 30%.

• Disseminated or extra-pulmonary NTM disease

• Has been previously treated with omadacycline
