Exclusion criteria
Exclusion criteria: Subjects are not eligible for the trial if they meet one or more of the exclusion criteria listed below: 1) known bronchiectasis as a consequence of cystic fibrosis (CF); 2) known history of hypogammaglobulinaemia requiring treatment with immunoglobulin, unless fully replaced and considered immuno-competent by the Investigator; 3) myasthenia gravis or porphyria; 4) severe cardiovascular disease such as severe uncontrolled hypertension, ischaemic heart disease or cardiac arrhythmia and any other conditions that would confound the evaluation of safety, in the opinion of the Investigator; 5) had major surgery in the 3 months prior to the Screening Visit (Visit 1) or planned inpatient major surgery during the study period; 6) receiving treatment for ABPA; 7) had massive haemoptysis (greater than or equal to 300 mL or requiring blood transfusion) in the preceding 4 weeks before the Screening Visit (Visit 1) or between Visit 1 and Visit 2; 8) respiratory failure that would compromise patient safety or confound the evaluation of safety or efficacy of the study in the opinion of the Investigator; 9) current active malignancy, except for basal cell carcinoma or squamous cell carcinoma of the skin without metastases; 10) taking immunosuppressive medications (such as azathioprine, cyclosporine, tacrolimus, sirolimus, mycophenolate, rituximab), and/or anti-cytokine medications (such as anti-IL-6 and anti-tumour alpha necrosis factor products) in the preceding year before the Screening Visit (Visit 1); 11) known history of human immunodeficiency virus (HIV); 12) current treatment for non-tuberculous mycobacterial (NTM) lung disease or tuberculosis; 13) known or suspected to be allergic or unable to tolerate colistimethate sodium (intravenous or inhaled) or other polymixins, including evidence of bronchial hyper-reactivity following inhaled colistimethate sodium; 14) treatment with long term (= 30 days) prednisone at a dose of greater than 15 mg a day (or equivalent dose of any other corticosteroid) within six months of the Screening Visit (Visit 1); 15) new maintenance treatment with any oral macrolides (e.g. azithromycin/erythromycin/clarithromycin) within 30 days of the Screening Visit (Visit 1) or started between Visit 1 and Visit 2; 16) use of any intravenous or intramuscular or oral or inhaled anti-pseudomonal antibiotic (except chronic macrolides with a stable dose) within 30 days prior to the Screening Visit (Visit 1) and between Visit 1 and Visit 2; 17) pregnant or breast-feeding or plan to become pregnant over the next year or of child-bearing potential and unwilling to use a reliable method of contraception for at least one month before randomisation and throughout their involvement in the trial; 18) significant abnormality in clinical evaluations and/or laboratory tests (physical examination, vital signs, haematology, clinical chemistry, clinically relevant impaired renal function, defined as serum creatinine levels =2.0x upper limit of normal, ECG) endangering the safe participation of the patient in the study at the Screening Visit (Visit 1) and during the study; 19) participated in another investigational, interventional trial within 30 days prior to the Screening Visit (Visit 1); 20) in the opinion of the Investigator not suitable for inclusion for whatever reason.

Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of the trial is to investigate the effect of the use of inhaled colistimethate sodium, administered twice daily via the I-neb for 12 months, compared to placebo in subjects with NCFB chronically infected with P. aeruginosa on the frequency of pulmonary exacerbations.;Secondary Objective: The secondary objectives are to investigate the effect of the use of inhaled colistimethate sodium, administered twice daily via the I-neb for 12 months compared to placebo in subjects with NCFB chronically infected with P. aeruginosa, on: - the time to the first pulmonary exacerbation - the number of exacerbation-free days - the severity of pulmonary exacerbations - the time to the first severe pulmonary exacerbation - the Quality of Life - the pharmaco-economic effect - the density and susceptibility of P. aeruginosa and to investigate the emergence of other bacterial colonies and any developing resistance - the safety and tolerability of inhaled colistimethate sodium;Primary end point(s): Primary Efficacy Variable The primary variable for this trial is the mean annual NCFB pulmonary exacerbation rate ;Timepoint(s) of evaluation of this end point: along the study | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Secondary Efficacy Variables 1. time (in days) from the first dose of IMP until the first pulmonary exacerbation; 2. annualised number of pulmonary exacerbation-free days; 3. number of severe pulmonary exacerbations defined as those requiring intravenous antibiotics and/or hospitalisation; 4. the time (in days) from the first does of IMP until the first severe pulmonary exacerbation; 5. QoL as measured by the total scores of the SGRQ and QOL-B questionnaires as well as changes in SGRQ and QOL-B from baseline to each post-baseline visit; 6. number of days of work absence due to pulmonary exacerbations; 7. P. aeruginosa density as determined by the mean change in log10 CFU/g sputum from baseline (Visit 2) to Day 28 of treatment (Visit 3) as well as to Visits 5 and 7. Safety Variables 8. the incidence of TEAEs; 9. absolute changes in percent-predicted FEV1 from baseline to each post-baseline visit; 10. the number of subjects experiencing bronchospasm clinically or spirometrically determined following IMP administration at the start and end of treatment; 11. P. aeruginosa resistance to colistin sulfate as determined by in-vitro susceptibility testing on sputum from Screening (Visit 1) to end of treatment (Visit 7) as well as on sputum from Exacerbation Visits and clinic visits due to pneumonia; 12. emergence of other bacterial colonies and any developing resistance in sputum from Screening (Visit 1) to End of Treatment (Visit 7); 13. haematology, clinical chemistry and renal function tests; 14. physical examination and vital signs data; 15. 12-lead electrocardiogram. ;Timepoint(s) of evaluation of this end point: Secondary Efficacy Variables 1 from first dose until first pulmonary exacerbation 2 and 3 along the study 4 from first does until first severe pulmonary exacerbation 5 from baseline to each post-baseline visit 6 along the study 7 from baseline (Visit 2) to Day28 (Visit 3) and to Visits 5 & 7 Safety Variables 8 along the study 9 from ba | — |
