Official title

Assessing the Adequacy of the Evaluating Respiratory Symptoms in COPD (E-RS:COPD™) Measure Among Patients With Moderate to Severe Asthma

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Asthma and chronic obstructive pulmonary disease (COPD) are chronic inflammatory conditions involving the small airways with airflow limitations resulting from genetic and environmental interactions. Currently, there are no existing subject diaries with evidence of responsiveness to measure the daily symptoms of asthma. Therefore, there is a need to either develop a new symptom diary to characterize subject burden of asthma symptoms or modify/adapt an existing tool from a related disease area for use in subjects with moderate to severe asthma. The E-RS in COPD (E-RS: COPD®) questionnaire was developed as a measure of daily respiratory symptoms associated with COPD. The fixed dose combination of fluticasone furoate/ umeclidinium/ vilanterol (FF/UMEC/VI) administered via the ELLIPTA® dry powder inhaler (DPI) has been developed for the treatment of asthma. This cross-sectional, qualitative study is designed to understand the symptoms and disease experience of subjects with moderate to severe asthma. This study will also evaluate underlying concepts that are most important to asthmatic subjects compared to symptoms and concepts included in the E-RS: COPD and two supplemental asthma items (wheeze and shortness of breath with physical activity). Approximately 32 subjects will be included in the study and interviewed via telephone. Each interview including time for consent, qualitative interview, and completion of case report forms (CRFs) is expected to last approximately 60 to 90 minutes. Subjects will be expected to complete a daily diary for the next 7 days, following the initial telephone interview.
