| Primary | Change in Semi-Quantitative Mycobacterial Culture Results From Baseline to Day 84. | The endpoint used the 7-step semi-quantitative scale (SQS) for mycobacterial culture reporting in both solid and liquid growth media, with step 1 = culture negative in both solid and liquid media, step 2 = growth in liquid medium only, 3 = solid medium positive, 4 = 50 to 100 colonies in solid medium & growth in liquid, 5 = >100 to 200 colonies in solid medium & growth in liquid, 6 = >200 to 500 colonies in solid medium & growth in liquid, 7 = >500 colonies in solid medium & growth in liquid. Full scale range is 1 (best score) to 7 (worst score). The change in step measures the growth at Day 84 compared to the growth at Baseline. The negative values represent reduction in colony growth. | | Posted | | Count of Participants | | Participants | | Baseline and end of double-blind phase of 84 days | | | | ID | Title | Description |

| The primary efficacy analysis tested the following hypotheses:
- H0: There is no difference at Day 84 between the LAI arm and the placebo arm
- Ha: There is a difference at Day 84 between the LAI arm and the placebo arm
Statistical analysis applies to all day 84 rows. | Wilcoxon rank sum test | | 0.072 | Conducted in the mITT population using a stratified Wilcoxon rank sum test, to compare the treatment arms at a 2-sided significance level of 0.05, adjusting for the randomization strata (presence/absence of CF and MAC versus Mycobacterium abscessus). | | | | | | | | | | | | | Superiority | |

| Secondary | Number of Subjects With Negative NTM Culture for the LAI Arm at Day 84 Compared to the Placebo Arm at Day 84 | Sputum specimens were cultured in liquid media in addition to solid media (agar). If results were negative on agar, the liquid media was held for 6 weeks before reporting as culture negative. Culture was negative when confirmed with no growth in liquid medium. | | Posted | | Count of Participants | | Participants | | 84 days double-blind phase | | | | ID | Title | Description |

| Secondary | Change From Baseline in Respiratory and Systemic Symptoms Questionnaire (RSSQ) Score at Day 84 for the LAI Arm Compared to the Placebo Arm | The RSSQ was administered to gather information from the subject about the types of symptoms that the subject has experienced since the last contact. A reduction in score indicates improvement. The range of values for the scores are -2 (best) to +2 (worst) in whole numbers. The composite score was calculated by averaging the scores of the subscales. | | Posted | | Mean | Standard Deviation | units on a score | | Baseline to day 84. | | | | ID | Title | Description |
