According to the results reported on ClinicalTrials.gov, this trial (NCT03460704) enrolled 152 people in the Colistimethate Sodium (CMS) group and 135 people in the placebo group, for a total of 287 participants. The trial was measuring how often people with a lung condition called non-cystic fibrosis bronchiectasis experienced "pulmonary exacerbations" — that is, episodes where their symptoms (such as increased cough, more mucus, breathlessness, or fever) worsened significantly and a doctor prescribed antibiotic tablets or injections to treat them. The study tracked how many of these episodes each person had over the course of a year. The reported data shows that the average number of these worsening episodes per year was 0.889 in the CMS group and 0.885 in the placebo group. In plain terms, both groups experienced less than one such episode per person, on average, over the year, and the two numbers were very close to each other. It is worth noting that a portion of participants did not complete the study — 58 people in the CMS group and 46 in the placebo group — though the reasons for not completing were not detailed in the data provided here. No secondary outcome measure data was included in the information provided, so those results cannot be described here. These are the results as reported to ClinicalTrials.gov.

Who may be able to join
AI generated eligibility summary. Written by an AI model from the official source data and checked on a sample basis. It can contain mistakes, so confirm anything important against the original source. How we use AI
Who might be able to join this trial:
- People who are able and willing to give their written consent after having the study fully explained to them
- People aged 18 years or older, of any gender
- People who have been diagnosed with non-cystic fibrosis bronchiectasis (a lung condition causing widened, damaged airways) confirmed by a CT or high-resolution CT scan, and this is their main condition being treated
- People who have had at least 2 chest flare-ups related to their bronchiectasis requiring antibiotic tablets or inhaled antibiotics, or at least 1 flare-up requiring antibiotic drip, in the 12 months before the first study visit — and no flare-ups between the first and second study visits
- People who have a recorded history of a lung infection caused by a bacteria called Pseudomonas aeruginosa
- People who have been medically stable and have not needed any changes to their lung treatment for at least 30 days before the first study visit
- People whose lung function test (a breathing test measuring how much air can be blown out) shows a result of at least 25% of the expected normal value
- People whose mucus sample (sputum test) taken at or around the first study visit shows a positive result for Pseudomonas aeruginosa bacteria
Who may not be able to join:
- People whose bronchiectasis is caused by cystic fibrosis
- People with a condition called hypogammaglobulinaemia (low immune proteins in the blood) who need treatment with immunoglobulin, unless the trial doctor considers their immune system to be fully functioning
- People with myasthenia gravis (a muscle weakness disorder) or porphyria (a rare metabolic disorder)
- People with serious heart or blood pressure conditions, such as severe uncontrolled high blood pressure, heart disease, or irregular heartbeat, or any other condition the trial doctor believes could affect safety
- People who had major surgery in the 3 months before the first study visit, or who have major surgery planned during the study
- People currently being treated for a fungal lung condition called allergic bronchopulmonary aspergillosis (ABPA)
- People who have coughed up a large amount of blood (300 mL or more, or enough to need a blood transfusion) in the 4 weeks before the first study visit, or between the first and second study visits
- People with breathing failure severe enough that the trial doctor considers it a safety risk or likely to affect study results
- People with an active cancer, except for certain non-spreading skin cancers (basal cell carcinoma or squamous cell carcinoma without spread)
- People who have taken immune-suppressing medications (such as azathioprine, cyclosporine, tacrolimus, sirolimus, mycophenolate, or rituximab) or anti-inflammatory biological medications (such as anti-IL-6 or anti-TNF products) in the year before the first study visit
- People with a known history of HIV infection
- People currently being treated for tuberculosis or a related lung infection called non-tuberculous mycobacterial (NTM) lung disease
- People who are known or suspected to be allergic to, or unable to tolerate, a medication called colistimethate sodium (given by drip or inhaler) or similar antibiotic medicines called polymyxins, including those who have had airway sensitivity reactions to inhaled colistimethate sodium
- People who started long-term use (30 days or more) of prednisone at a dose greater than 15 mg per day (or an equivalent steroid dose) within six months of the first study visit
- People who started a new ongoing course of certain antibiotics called macrolides (such as azithromycin, erythromycin, or clarithromycin) within 30 days of the first study visit, or between the first and second study visits
- People who used any antibiotic specifically targeting Pseudomonas aeruginosa (given by drip, injection, tablet, or inhaler — except stable-dose macrolides) within 30 days before the first study visit, or between the first and second study visits
- People who are pregnant, breastfeeding, planning to become pregnant in the next two years, or who could become pregnant but are unwilling to use a reliable form of contraception from at least one month before being assigned to a treatment group and throughout the study
- People with significant abnormal results on physical checks, blood tests, kidney function tests (specifically, creatinine levels at or above twice the upper limit of normal), heart tracing (ECG), or other clinical tests that the trial doctor considers a safety concern
- People who have taken part in another clinical intervention trial within 30 days before the first study visit
- People whom the trial doctor considers unsuitable for inclusion for any reason
