Pharmacotherapy for the Different Phenotypes of Airways Disease
Scientific title
In a random community sample of people 18-75 years with wheeze and dyspnea, does the response to salbutamol 400 mcg once, iprotropium 80 mcg once or budesonide 800 mcg daily for 12 weeks differ between airways disease phenotypes in lung function, disease control and quality of life?

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
1. Ipratropium 80 mcg inhaled single dose
2.Salbutamol 400 mcg inhaled single dose
3. Budesonide 400 mcg inhaled twice daily for 12 weeks

All participants will receive all interventions in the sequence 1, 2, 3. Interventions 1 and 2 to be administered 1-4 weeks apart. Intervention 3 to be administered over the 12 weeks immediately following intervention 2.
Intervention code [1] 256693 0
Treatment: Drugs
Comparator / control treatment
The effect of each of the three interventions will be compared across phenotype groups. All participants will receive the same three interventions in the same order; effectively there will be three independent uncontrolled trials. No control intervention or comparison between interventions is planned.
Control group
Uncontrolled

Outcomes
Primary outcome [1] 258649 0
difference in forced expiratory volume in one second (FEV1) response to ipratropium between groups. This will be measured by spirometry.
Timepoint [1] 258649 0
At baseline and 30 minutes following administration of ipratropium.
Primary outcome [2] 258654 0
difference in FEV1 response to salbutamol between groups. This will be measured by spirometry.
Timepoint [2] 258654 0
At baseline and 30 minutes following administration of salbutamol.
Secondary outcome [1] 264628 0
Change in symptoms and control of airways disease in response to inhaled corticosteroid as measured by Asthma Control Questionnaire.
Timepoint [1] 264628 0
At baseline and 12 weeks following commencement of treatent.

Summary
Brief summary
Chronic obstructive pulmonary disease (COPD) and asthma are the most common respiratory diseases in the community. People with these diseases differ in the way the disease manifests itself and some people have features of both diseases. We know that the best medications for asthma and COPD are different but we do not know if best treatment differs between the different types of asthma, COPD and the overlap of the two conditions. This study will answer this question by identifying people in the community with respiratory disease, assessing how the disease manifests in individuals and the effectiveness of three different standard inhaled medications. We will then group individuals into different clusters (types or patterns of disease manifestation) and determine which clusters respond to which different medication. This information will guide doctors who are treating these diseases.
