Safety and Tolerability Study of 2 Dose Level of Arikayce™ in Patients With Bronchiectasis and Chronic Infection Due to Pseudomonas Aeruginosa.

June 20, 2019 updated by: Insmed Incorporated

A Placebo Controlled, Randomized, Parallel Cohort, Safety And Tolerability Study Of 2 Dose Levels Of Liposomal Amikacin For Inhalation (Arikayce™) In Patients With Bronchiectasis Complicated By Chronic Infection Due To Pseudomonas Aeruginosa.

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.

Study Overview

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.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
Baseline to Day 14, Day 28 and Day 42.
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.

Baseline to Day 14, Day 28, Day 42 and Day 56.
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.
Day 1 to Day 14, Day 28, Day 42 and Day 56.
To Evaluate the Use of Systemic Antipseudomonal Rescue Therapy
Time Frame: Screening to Day 56.
Screening to Day 56.
