Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A randomised, placebo-controlled trial of inhaled fluticasone propionate (500 Mmicrograms twice daily) over six months on airway inflammation in mild to moderate COPD.
Intervention code [1] 1736 0
Treatment: Drugs
Comparator / control treatment
The placebo is delivered via an identical metered dose inhaler device delivering a dry powder and the number of puffs and frequency are the same as the active FP arm.
Control group
Placebo

Outcomes
Primary outcome [1] 2662 0
Change in cellular airway inflammation as assessed by sputum, bronchoalveolar lavage and endobronchial biopsy.
Timepoint [1] 2662 0
Assessed at baseline and after six months intervention.
Secondary outcome [1] 4519 0
Clinical symptoms (daily diary card) and the St George's Respiratory Questionnaire.
Timepoint [1] 4519 0
Baseline and six months
Secondary outcome [2] 4520 0
Improvements in lung function.
Timepoint [2] 4520 0
Measured by spirometry at monthly intervals throughout the study.

Eligibility
Key inclusion criteria
A physician diagnosis of COPD and evidence of airflow limitation on spirometry.
Minimum age
40 Years
Maximum age
75 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Potential participants were interviewed and examined by a respiratory physician and any history suggestive of asthma, i.e. symptoms present in childhood, related atopic disorders, eczema or hay fever, significant day-to-day variability or prominent nocturnal symptoms, or a history of wheeze rather than progressive breathlessness and any previous use of ICS excluded that subject from further participation. Other exclusion criteria included significant uncontrolled co-morbidities such as diabetes, angina or cardiac failure, and other co-existing respiratory disorders, i.e. pulmonary fibrosis, lung cancer and bronchiectasis.

Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects were recruited by advertisement in local newspapers and placement of posters in clinic waiting areas in the hospital as well as on the notice boards of social and Veterans Affairs clubs. Potential participants were screened by a research nurse and physician. If eligible, they were randomised in the Hospital Pharmacy to the two trail treatments; fluticasone or placebo. The inhaled medications were dispensed from Pharmacy in identical inhaler devices and the research nurse and physician were blinded to treatment allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computerised generated random number programme designed to randomise subjects to fluticasone or placebo.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
Patients were blinded to treatment and the investigators and research nurse were blinded to treatment. Results were all analysed by researchers blinded to treatment, i.e. cell counts were undertaken on coded slides with no information whatsoevr on subject, date or treatment.
