Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Randomised Controlled Trial of the efficacy and safety of an Inhaled Corticosteroid / Long Acting Beta Agonist reliever therapy regimen in asthma
Scientific title
A 52-week, open label, parallel group, multicentre, phase III, randomised controlled trial to compare the efficacy and safety of salbutamol metered dose inhaler taken as required for relief of symptoms, and budesonide/formoterol Turbuhaler taken as required for relief of symptoms, and regular budesonide Turbuhaler plus salbutamol metered dose inhaler taken as required for relief of symptoms, in adult patients with asthma.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The central electronic Case Report Form (eCRF) system will perform randomisation. It will conceal the allocations and will release a participant’s randomisation outcome only at the time of randomisation. The randomisation schedule will not be accessed by study staff.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer-generated randomisation number sequence will be created by the study statistician, independent of the investigators undertaking recruitment and subsequent visits.
Randomisation will be stratified by country.
