Trial outcomes

Primary outcomes

1

Forced Expiratory Volume in 1-second (FEV1)

Difference between study arms in absolute change from baseline for post-bronchodilator FEV1 score at 1 year (value at 1 year minus value at baseline).

Time frame
1-year

Secondary outcomes

1

FEV1 Post-bronchodilator Absolute Change

Difference between study arms in absolute change from baseline for post-bronchodilator FEV1 score at 1 year (value at 1 year minus value at baseline).

Time frame
1 year
2

St. George's Respiratory Questionnaire (SGRQ)

Difference between study arms in 'absolute change from baseline' for SGRQ score at 1 year (value at 1 year minus value at baseline). The St. George's Respiratory Questionnaire measures health status (quality of life) in patients with diseases of airways obstruction. The questionnaire comprises of two parts: Part I: Symptoms (frequency \& severity) Part II: Activities that cause or are limited by breathlessness; Impacts (social functioning, psychological disturbances resulting from airways disease) A Total score is calculated which summarizes the impact of the disease on overall health status. Scores range from 0 to 100, with higher scores indicating more limitations.

Time frame
1 year
3

6-minute Walk Distance

Difference between study arms in 'absolute and percentage change from baseline' for 6MWD at 1 year (value at 1 year minus value at baseline).

Time frame
1 year
