Brief Summary:

The purpose of this study is to evaluate the efficacy, safety and tolerability of 84 days of daily dosing of 590 mg of LAI versus placebo in patients with treatment refractory NTM lung disease.

The first part of the study is the 84-day double-blind phase to evaluate the primary and secondary endpoints.


Condition or disease Intervention/treatment Phase
Mycobacterium Infections, Nontuberculous Drug: Liposomal amikacin for inhalation (LAI) Drug: placebo Phase 2

Detailed Description:

This was a Phase 2, randomized, double-blind study of efficacy, safety, and tolerability of once daily (QD) dosing of LAI 590 mg versus placebo for 84 days in subjects with treatment refractory NTM lung infection on a stable multidrug regimen. At the conclusion of the randomized double-blind phase of the study, subjects who consented to continue in the open-label phase of the study received LAI 590 mg QD for 84 additional days. All subjects were required to complete a 28-day safety follow-up after their end of treatment study visit (Day 168). Subjects completing this study were consented for enrollment in a long-term follow-up phase and were asked to return to the study site at 12 months and 24 months (per protocol Amendment #3, the 24-month follow-up visit was no longer required) (visit window ± 2 months) after the last dose of study drug (either after completing the randomized double-blind phase or the open-label phase). Subjects were stratified upon entering the study based on the presence or absence of cystic fibrosis (CF) and Mycobacterium avium complex versus M abscessus as the predominate NTM organism at baseline and were block randomized to receive either LAI or placebo in a 1:1 ratio in the double-blind phase.

Subjects completing the main study, and subjects who completed the 84-day open-label phase, were consented for enrollment in a post-LAI safety follow-up assessment and were asked to return to the study site 12 months (visit window ± 2 months) after the last dose of study drug (either after completing the randomized double-blind phase or the open-label phase). The screening period required obtaining 3 morning sputum specimens (spontaneous or induced) for mycobacteriology. At each post-screening sputum timepoint, at least 2 and preferably 3 sputum specimens were obtained. At Day 1 (baseline), subjects were evaluated pre-dose and post-dose at the study site. Subjects returned to the study site briefly on Day 2 for collection of serum samples to determine creatinine clearance. On Days 28, 56, and 84, study drug was administered at the site and the efficacy, safety, and tolerability of study drug were evaluated. At Day 85, those subjects continuing in the open-label phase of the study received LAI 590 mg at the study site with pre-dose and post-dose assessments for safety and efficacy. Subjects returned every 28 days (Days 112, 140, and 168) in the open-label phase. A 28-day, post-dose follow-up visit occurred at either Day 112 for those subjects who did not continue in the open-label phase or at Day 196 for those subjects who continued in the open-label phase.

Subjects completing the main study, and subjects who completed the 84-day open-label phase, were consented for enrollment in a post-LAI safety follow-up assessment and were asked to return to the study site 12 months (visit window ± 2 months) after the last dose of study drug (either after completing the randomized double-blind phase or the open-label phase). Arikace™, Arikayce™, Liposomal Amikacin for Inhalation (LAI), and Amikacin Liposome Inhalation Suspension (ALIS) may be used interchangeably throughout this study and other studies evaluating amikacin liposome inhalation suspension.

Primary Outcome Measures :
  1. Change in Semi-Quantitative Mycobacterial Culture Results From Baseline to Day 84. [ Time Frame: Baseline and end of double-blind phase of 84 days ]
    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.


Secondary Outcome Measures :
  1. Number of Subjects With Negative NTM Culture for the LAI Arm at Day 84 Compared to the Placebo Arm at Day 84 [ Time Frame: 84 days double-blind phase ]
    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.

  2. Time to Negative NTM Culture….During the 84-day Double-blind Treatment Phase [ Time Frame: 84 days double-blind phase ]
    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.

  3. Ordinal, 3-level Response From Baseline on the SQS for Mycobacterial Culture for the LAI Arm at Day 84 Compared to the Placebo Arm at Day 84 [ Time Frame: Baseline and end of double-blind phase of 84 days ]
    The ordinal, 3-level response are (1) improvement (2) no change (3) worsening or death

  4. Change From Baseline in Respiratory and Systemic Symptoms Questionnaire (RSSQ) Score at Day 84 for the LAI Arm Compared to the Placebo Arm [ Time Frame: Baseline to day 84. ]
    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.

  5. Change From Baseline in Global Rating of Health (GRH) at Day 84 for the LAI Arm Compared to the Placebo Arm [ Time Frame: Baseline and end of double-blind phase of 84 days ]
    The assessing physician asked the subject to rate his/her assessment of health according to the GRH. Subject responses to, "How would you rate your health at the present time?" included: Excellent, Good, Fair, or Poor.

  6. Number of Participants Requiring "Rescue" Anti-mycobacterial or Other "Rescue" Drugs During the 84-day Double-blind Phase [ Time Frame: 84 days double-blind phase ]
    Per the study protocol, study subjects were on a stable, multi-drug, anti-mycobacterial regimen based on the 2007 ATS/IDSA Guidelines; the regimen should not have changed during the study period except for safety concerns. The need for changes to the concurrent anti-mycobacterial regimen or "rescue" therapy was at the discretion of the Investigator and was tracked as a study outcome.

  7. Number of Subject for "Rescue" Anti-mycobacterial or Other "Rescue" Drugs During the 84-day Double-blind Phase [ Time Frame: 84 days double-blind phase ]
    Per the study protocol, study subjects were on a stable, multi-drug, anti-mycobacterial regimen based on the 2007 ATS/IDSA Guidelines; the regimen should not have changed during the study period except for safety concerns. The need for changes to the concurrent anti-mycobacterial regimen or "rescue" therapy was at the discretion of the Investigator and was tracked as a study outcome.
