Brief summary: This is an open-label safety extension study to assess the safety and tolerability of once daily dosing of 590 mg Liposomal Amikacin for Inhalation (LAI) added to a multi-drug regimen in participants with nontuberculous mycobacterial (NTM) lung infections due to Mycobacterium avium complex (MAC) who were refractory to therapy and failed to convert in Study INS-212 (NCT02344004).

Detailed description: Safety and tolerability of once daily dosing of 590 mg Liposomal Amikacin for Inhalation (LAI) added to a multi-drug regimen in participants with non-tuberculous mycobacterium (NTM) lung infections due to Mycobacterium avium complex (MAC) who are refractory to therapy and failed to convert in Study INS-212.

Participants participating in Study INS-212 who had not achieved the INS-212 protocol definition of culture conversion (3 consecutive monthly negative sputum cultures) or who had experienced a relapse or recurrence (agar positive or more than 2 consecutive broth positive results after culture conversion had occurred) by Month 6, as determined by their sputum culture results from Day 1 through Month 6 and confirmed at their scheduled Month 8 visit, were eligible to participate in Study INS-312. For participants who chose to participate in Study INS-312, the Month 8 visit of Study INS-212 became their end of treatment (EOT) visit; these participants were then asked to provide written informed consent for Study INS-312 and were enrolled directly into Study INS-312 after having met all eligibility criteria.

Participants in Study INS-212 had either received 590 mg LAI plus an MDR (LAI + MDR arm) or a multidrug regimen alone (MDR alone arm). All participants in this safety extension study were to continue the multidrug antimycobacterial regimen that they were receiving during Study INS-212 and will receive LAI 590 mg administered daily (QD) for up to 12 months. The participants will remain in the study for up to a total of 13 months (up to 12 months on-treatment plus 1 month off LAI treatment for safety follow up).

Eligibility criteria: Key Inclusion Criteria:

1. had successfully completed the Month 6 and End of Treatment visits in Study INS-212
2. had not achieved the INS-212 protocol definition of culture conversion by Month 6 in Study INS-212 OR had experienced a relapse or recurrence by Month 6 in Study INS-212.

Key Exclusion Criteria:

1. achieved culture conversion without relapse or recurrence in the Study INS-212 study by Month 6
