Conditions: Bronchiectasis
Keywords: Ciprofloxacin Dry Powder for Inhalation Exacerbation Bronchiectasis
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 416
Healthy volunteers: no

Brief summary:
The purpose of this study is to evaluate if the time to first pulmonary exacerbation of bronchiectasis or its frequency can be prolonged by inhalation of ciprofloxacin for 28 days every other 28 days or for 14 days every other 14 days over 48 weeks.

Detailed description:
Number of participants with Adverse events will be covered in Adverse Events section.

The statistical analysis tests for the efficacy variables will be performed hierarchically. The comparisons ciprofloxacin DPI vs. pooled placebo (according to statistical analysis plan defined for FDA registration) will be performed in parallel for the regimen 28 days on/off and 14 days on/off.

Arms:
arm 1: Participants received ciprofloxacin (BAYQ3939) 32.5 milligram (mg) corresponding to 50 mg dry powder for inhalation (DPI) administered twice daily (BID) (every 12 hours); a treatment cycle consisted of a 28-day on-treatment phase followed by a 28-day off-treatment phase (48 weeks treatment phase = 6 active cycles). arm 2: Participants received ciprofloxacin 32.5 mg corresponding to 50 mg DPI administered BID (every 12 hours); a treatment cycle consisted of a 14-day on-treatment phase followed by a 14-day off-treatment phase (48 weeks treatment phase = 12 active cycles). arm 3: Participants received placebo matched to ciprofloxacin 32.5 mg powder (containing 40 mg dry powder) administered BID (every 12 hours); a treatment cycle consisted of a 28-day on-treatment phase followed by a 28-day off-treatment phase (48 weeks treatment phase = 6 cycles). arm 4: Participants received placebo matched to ciprofloxacin 32.5 mg powder (containing 40 mg dry powder) administered BID (every 12 hours); a treatment cycle consisted of a 14-day on-treatment phase followed by a 14-day off-treatment phase (48 weeks treatment phase = 12 cycles).

Interventions: intervention 1: Ciprofloxacin DPI (BAYQ3939) intervention 2: Placebo
Intervention descriptions: intervention 1: Participants received 32.5 mg ciprofloxacin hydrated (corresponding to 50 mg dry powder) administered BID (every 12 hours) using T-326 powder inhaler device. intervention 2: Participants received placebo matched to ciprofloxacin 32.5 mg powder (containing 40 mg dry powder) administered BID (every 12 hours) using T-326 powder inhaler device.
