Description of intervention(s) / exposure
This is a Phase 2a, international, multicenter, randomized, double-blind, placebo controlled study designed to evaluate safety and efficacy of the mixture formulation consisting of liposomal and free ciprofloxacin for inhalation compared to placebo for inhalation in patients with non CF bronchiectasis with chronic lung infection. Patients will be enrolled in this study for 6 months. This study will consist of a 14 day Screening Phase and a Treatment Phase consisting of three 28 day On treatment Periods (Months 1, 3, and 5) and three 28 day Off treatment Periods (Months 2, 4, and 6). Patients will have a one week wash out period after each treatment period.

Patients will be randomised to receive one of the following inhaled treatment regimens, which will be administered via nebulizer once daily during the three 28 day On-treatment Periods (Months 1, 3, and 5):
Mixture Formulation, which consists of the following:
Liposomal Ciprofloxacin and
Free Ciprofloxacin Or Placebo.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
After signing the consent form, each patient will be assigned a screening number. This will be done via an e-mail based computer system that will generate randomization sequence numbers for each screened patient. Patients who drop out of the study before randomization will retain their screening number. Randomization will occur at Visit 1 after all screening procedures have been performed and eligibility for the study is confirmed. Patients will be randomized to either receive the mixture formulation or placebo.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
After signing the consent form, each patient will be assigned a screening number. Randomisation numbers are generated by a computer software system.
