A double-blind, vehicle-controlled, multi-centre, clinical study to investigate the efficacy and safety of up to 6 months of therapy with inhaled Promixin® in the treatment of patients with non-cystic fibrosis bronchiectasis infected with Pseudomonas aeruginosa susceptible to Promixin®
Promixin® (colistimethate sodium) is currently approved for use in the management of patients with cystic fibrosis (CF) bronchiectasis who have pseudomonal lung infections, but not for use in patients with non-CF bronchiectasis who have pseudomonal lung infections. The infective agent is the same in both cases and it could be expected that Promixin® will provide benefit in patients with non-CF bronchiectasis as well as patients with CF bronchiectasis.
The purpose of this study is to determine if the use of inhaled colistimethate sodium (Promixin®) increases the time, compared to vehicle, from starting treatment with the investigational medicinal product (IMP) until the patients experience an infective pulmonary exacerbation, in patients with non-CF bronchiectasis infected with Pseudomonas aeruginosa (P. aeruginosa) susceptible to Promixin®. Treatment will be for up to 6 months and the safety profile of inhaled Promixin® therapy will be evaluated over this period.
On 28/09/2011 the following changes were made to the trial record:
1. The anticipated end date was changed from 26/08/2010 to 31/01/2012.
2. The Russian Federation and Ukraine have been added to the countires of recruitment.
3. The target number of participants was changed from 260 to 144; recruitment is now complete.

Promixin® (colistimethate sodium)
Primary outcome measure
The time (in days) from baseline/visit 2 (first dose) for each individual patient, until he/she experiences an exacerbation.
Secondary outcome measures
1. Number of adverse events and serious adverse events, measured at end of the patients' involvement in the study
2. Changes in sputum mass from baseline to week 4
3. Changes in sputum flora, measured over the course of the study, samples collected at weeks 4, 12 and at the end of the patients' involvement in the study
4. Improvement in quality of life as assessed by Saint George's Respiratory Questionnaire (SGRQ) and compliance with treatment, measured at week 12 and at the end of the patients' involvement in the study
5. Changes in forced expiratory volume in one second (FEV1), measured at the end of the patients' involvement in the study and at the first dose
