Timeframe: At baseline and after 3 months

Population: ITT population

Mean absolute change in the Modified Medical Research Council (mMRC) Dyspnea Score from Baseline to 3 months in the EBV group compared to the SoC group. The mMRC (Modified Medical Research Council) stratifies severity of dyspnea in respiratory diseases. The severity of dyspnea is rated on a scale of 0 to 4, with higher scores indicating more limitations.

Population: ITT population

Mean absolute change in the COPD Assessment Test (CAT) Total Score from Baseline to 3 months in the EBV group compared to the SoC group. The COPD Assessment Test (CAT) is an eight-item questionnaire designed to quantify the impact of COPD symptoms on the health status of patients. The CAT provides a score of 0-40 to indicate the impact of disease.

SECONDARY outcome

Timeframe: At baseline and after 3 months

Population: ITT population

Mean absolute change in the EQ-5D Summary Index from Baseline to 3 months in the EBV group compared to the SoC group. EQ-5D is a standardized instrument to measure health-related quality of life that can be used in a wide range of health conditions and treatments. The EQ-5D consists of a descriptive system and the EQ VAS. The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. The EQ-5D health states may be converted into a single summary index by applying a formula that attaches weights to each of the levels in each dimension. The maximum score of 1 indicates the best health state, while 0 indicates the worst health state.
