About
A major factor in the respiratory health of Cystic Fibrosis (CF) participants is the prevalence of chronic Pseudomonas aeruginosa (Pa) infections. The Pa infection rate in CF patients increases with age and by age 18 years approximately 85% of CF patients in the US are infected. Liposomal amikacin for inhalation (Arikayce™) was developed as a possible treatment for chronic infection due to Pa in CF patients.
The purpose of this study is to determine whether Arikayce™ is effective in treating chronic lung infections caused by Pa in CF participants. The effectiveness, safety, and tolerability of Arikayce™ will be compared to Tobramycin TOBI®, an inhalation antibiotic already available for use.
Full description
CF is a genetic disease resulting from mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Patients with CF manifest pathological changes in a variety of organs that express CFTR. The lungs are frequently affected often resulting in chronic infections by bacteria such as Pseudomonas aeruginosa and airway inflammation. Treatment of chronic lung infections is one of the principal goals of CF therapy. Arikayce™ LAI (liposomal amikacin for inhalation) is a sustained-release formulation of amikacin encapsulated inside nanoscale liposomal carriers designed for administration via inhalation. It is hypothesized that the sustained-release pulmonary targeting and biofilm penetration properties of this formulation will have several advantages over current therapies in treating CF patients with chronic lung infection caused by Pseudomonas aeruginosa.
This Phase 3 study has been designed to evaluate the efficacy, safety and tolerability of Arikayce™ in treating CF patients with chronic bronchopulmonary infection compared to a currently available antibiotic, TOBI® Inhalation Solution. Eligible participants will be randomized 1:1 to receive 590 mg of Arikayce™ once daily via a PARI Investigational eFlow® Nebulizer or 300 mg TOBI® BID via a PARI LC® PLUS nebulizer. Participants will receive 3 cycles of treatment with each cycle being comprised of 28 days on treatment followed by 28 days off-treatment. Total study duration is up to 186 days (~6 months) including an up to 18 day Screening period. Participants will be evaluated for safety, tolerability and efficacy bi-weekly during the first 4 weeks of treatment, and thereafter every 4 weeks for the duration of the study. Pharmacokinetics (PK) of Arikayce™ in blood, sputum and 24-hour urine will be determined in a subgroup of study participants who consent to PK evaluation.
At the completion of the TR02-108 protocol, participants who have consented and meet study safety criteria may enroll in the long-term, open-label, multi-cycle extension study of 590 mg of Arikayce™ (under a separate protocol TR02-110). 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.
