Brief summary
Three main classes of inhaled treatment exist for chronic obstructive pulmonary disease (COPD): Beta2-adrenergic agonists (which may be short (SABA) or long (LABA) acting), long-acting muscarinic acetylcholine receptor antagonists (LAMA), and inhaled corticosteroids (ICS). For subjects at higher risk of exacerbation, treatment with all these three classes of medication is recommended. This study aims to explore the potential utility of a device called single inhaler triple combination or fluticasone furoate/ umeclidinium/ vilanterol (FF/UMEC/VI) inhaler containing all three groups of compound. This is a mixed methods study with a qualitative phase and a quantitative Discrete Choice Experiment (DCE) phase and will be conducted in four stages: qualitative concept elicitation, DCE development, DCE piloting and testing, and conduct of the DCE. The study will conducted in the United Kingdom (UK), United States (US) and Germany and approximately 573 subjects with COPD will be included.
Interventions
Qualitative concept elicitation telephone interviews will be conducted in subjects with COPD to explore treatment effectiveness, symptoms, quality of life, and features of treatment that are considered to be most important to them when making treatment choices.
Qualitative concept elicitation in-person focus groups will be conducted in subjects with COPD to explore treatment effectiveness, symptoms, quality of life, and features of treatment that are considered to be most important to them when making treatment choices.
Draft version of the DCE surveys will be tested with subjects in cognitive interviews to explore the saliency of the attribute choices and assess whether the attributes are understandable, meaningful and comprehensive.
The modified DCEs will be piloted with subjects with COPD in each country to refine the underlying design and ensure that information is collected in an efficient way to enable the statistical analysis to be as precise as possible.
An online DCE survey questionnaire will be given to the subjects to identify subject preferences, priorities and treatment goals.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Evaluation of the key relevant attributes of COPD treatment | Up to 368 hours | The key attributes considered to be most important to subjects with COPD when making treatment choices will be assessed using the data from the subject interviews and focus groups. |
| Evaluation of the preferences, priorities and treatment goals of subjects with COPD for inhaled treatments | Up to 368 hours | The probability of choosing one treatment over another will be evaluated using DCE survey questionnaire. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Assessment of the relative appeal of different treatment approaches | Up to 371 hours | The burden of COPD, priorities in terms of symptoms and treatment effect, goals and preferences of subjects will be analyzed. |
| Estimation of the relative importance of each attribute | Up to 371 hours | The DCE online survey will be used to assess the relative importance of treatment attributes and priorities. |
