Brief Summary:
This is a study to determine the safety and tolerability of 28 days of daily dosing of two doses (280 mg and 560 mg) of Arikayce™ versus placebo in patients who have bronchiectasis and chronic infection due to Pseudomonas infection.

Condition or disease Intervention/treatment Phase
Bronchiectasis Drug: 280 mg Arikayce™ Drug: Matching Placebo for Cohort 1 Drug: 560 mg Arikayce™ Drug: Matching Placebo for Cohort 2 Phase 2

Detailed Description:

Bronchiectasis is a chronic disorder of the major bronchi and bronchioles characterized by permanent dilation, microbial infection, a persistent inflammatory response with the release of immune mediators and microbial toxins leading to destruction. The origin of bronchiectasis varies, but the presence of microbial infection and a persistent inflammatory response is typical of the disease. The chronic nature of the infection and the associated considerable morbidity provides the rationale for using aerosolized antibiotics for the treatment of bronchiectasis patients.

This is a multi-national Phase 2 study of safety and tolerability of 28 days of daily dosing with two dose levels (280 mg and 560 mg) of Arikayce™ versus placebo in subjects with bronchiectasis and chronic Pseudomonas infection. Study subjects will be randomized to receive either study drug or placebo by inhalation via a PARI eFlow® nebulizer. Each subject will complete 28 days of daily dosing. All study subjects will be followed for microbiologic activity for 14 days after completion of treatment and for safety for 28 days post completion of study treatment.

The total study duration will be 56 days, with the screening visit occurring within the preceding 14 days prior to study day 1. At Day 1 (baseline), subjects will be evaluated at pre-dose and during the first 4-5 hours post-dose. Subjects will return at Week 2 (day 14) after start of treatment and at the end of Week 4 (Day 28) treatment period to determine safety and efficacy of Arikayce™. Subjects will be followed up on study Days 42 and 56 (about 2 and 4 weeks after end of treatment) for safety determination. After completion of this study, subjects will be followed up for an additional 6 months via phone contacts and records review, if hospitalized or treated for pulmonary exacerbation (under the extension protocol).

Clinical laboratory parameters, audiology testing, clinical adverse events and pulmonary function will be evaluated for all study subjects in order to determine the qualitative and quantitative safety and tolerability of Arikayce™ compared to placebo. Serum, urine and sputum specimens will be collected at periodic intervals to assess pharmacokinetics (PK) in subjects who consent for the PK portion of the study. Additionally, sputum samples will be collected to determine changes in bacterial density. Total Pulmonary Symptom Severity Score (PSSS) will be assessed, and respiratory quality of life will be evaluated by using the St. George's Respiratory Questionnaire (SGRQ). Arikace™,Arikayce™, Liposomal Amikacin for Inhalation (LAI), and Amikacin Liposome Inhalation Suspension (ALIS) may be used interchangeably throughout this study and the other studies evaluating amikacin liposome inhalation suspension.

Primary Outcome Measures :
  1. Number of Participants Reporting Treatment-emergent AEs (TEAEs) up to End of Treatment [ Time Frame: Day 1 through 56. ]
    Number of Subjects reporting TEAE in the Arikayce™ groups and the placebo groups during the study. The table shows the events incidents, not the number of participants.

  2. Treatment-emergent Marked Laboratory Abnormalities up to 28 Days After Study Medication Discontinuation [ Time Frame: Day 1 through 56. ]
    Number of subjects reporting Incidence of clinically significant abnormalities in clinical values (Common Terminology Criteria for Adverse Events [CTCAE] grade >= 3) in Arikayce™ and placebo groups.

  3. Treatment-emergent Pulmonary Function Test (PFT) for Acute Tolerability Assessment [ Time Frame: Pre-dose, 0-1 hour post-dose and 2-4 hours post-dose on day 1, 0-1 hour post-dose and 2-4 hours post-dose on day 14, and 0-1 hour post-dose and 2-4 hours post-dose on day 28 ]
    Changes in PFT from pre-dose during the study were measured on Days 1, 14, and 28. Acute tolerability of the study treatment was assessed by examining the relative (rel.) changes in FEV1 from pre-dose assessments to 0-1 hour post-dose and 2-4 hours post-dose for each time point at which post-dose spirometry was conducted.

  4. Treatment-emergent PFT Abnormalities up to the End of Study [ Time Frame: Day 1, Day 14 and Day 28 ]
    Number of Subjects with Decrease of >= 15% in FEV1 (L) from Pre- to Post-dose by Study Day

  5. Number of Subjects With an Adverse Event Leading to Permanent Discontinuation of Study Medication [ Time Frame: Screening to Day 56 ]
  6. Serious Adverse Events up to 28 Days After Study Medication Discontinuation [ Time Frame: Screening to Day 56 ]
    Number of subjects with a SAE in the Arikace™ groups and the placebo group up to 28 days after study medication discontinuation. See SAE table in the safety section for details.


Secondary Outcome Measures :
  1. Change From Baseline in Log10CFU Per Gram (Density) of Pseudomonas Aeruginosa in Sputum. [ Time Frame: Baseline to Day 14, Day 28 and Day 42. ]
    The change in Pseudomonas aeruginosa density from from baseline to Day 14, 28, and 42 were evaluated.Treatment differences with respect to the changes from baseline to each measured study day, defined as the log10 of the sum of all morphotypes (colony-forming units [CFU]) per gram of sputum in (log10CFU/gram [g]), was estimated for each treatment group; standard deviations accompanied the treatment differences.

  2. Total Pulmonary Symptom Severity Score (PSSS) [ Time Frame: Baseline to Day 14, Day 28, Day 42 and Day 56. ]

    Changes in the severity and intensity (frequency x severity) of individual symptoms and change in composite PSSS from baseline to Days 14, 28, 42 and 56.

    The Pulmonary Symptom Severity Score (PSSS) was assessed on patient's responses to the Patients Symptoms Questionnaire, which employs symptom frequency and severity scales described for the validated Memorial Symptoms Assessment Scale. Symptom severity was scored on a scale of 0 (not applicable or symptom not present) to 4 (very severe) for each of the 5 symptoms (cough, shortness of breath, sputum production [frequency and severity], fatigue, and wheezing), and a composite score (range, 0 to 20 [low score represents better outcome]) was obtained as the sum of the severity scores for each symptom.


  3. To Evaluate Change in St. George's Respiratory Questionnaire Measurements [ Time Frame: Day 1 to Day 14, Day 28, Day 42 and Day 56. ]
    A composite total score is derived as the sum of domain scores for symptoms, activity, and impact, with 0 as the best possible score and 100 as the worst possible score. A reduction in score of 4 points is generally recognized as a clinically meaningful improvement in quality of life. This analysis compared the changes from Day 1 (prior to first dosing) to Days 14, 28, 42, and 56.

  4. To Evaluate the Use of Systemic Antipseudomonal Rescue Therapy [ Time Frame: Screening to Day 56. ]
