This study looked at a new way inhaled antibiotics can be made for people who have CF and a lung infection caused by pseudomonas aeruginosa. The antibiotic drug (Amikacin) has been made by wrapping it within microscopic bubbles called liposomes. It is thought that the lipsome will help the antibiotic get into the mucus to kill pseudomonas aeruginosa, and also slow down how quickly the Amikacin leaves the lung. The PARI eFlow electronic nebulizer was used in this study to give the Amikacin.

This placebo-controlled Phase 2 study enrolled 46 Adult CF subjects in the U.S. to evaluate the safety, tolerability, pharmacokinetics, and efficacy of three dose levels of Arikaceâ?¢ (70mg, 140 mg, 560 mg) administered daily for 28 days. A similar study was conducted in Europe but included one dose cohort at 280 mg. The combined results on 105 patients total were reported together and showed that patients in the 560 mg Arikace dose group showed improvement in lung function over baseline while patients on placebo declined over time.
More patients receiving Arikace vs those receiving placebo showed improvement in patient reported respiratory symptoms, reduction in Pseudomonas aeruginosa density, and prolonged time to pulmonary exacerbation.
Acute tolerability was similar across all groups and the treatment was well tolerated. Adverse effects were consistent with those expected in a population of CF patients receiving inhalation medications.
