|
Week 12, 24 and 52 after treatment
|
|
Change from baseline in DLCO
Zeitfenster: Week 12, 24 and 52 after treatment

|
Week 12, 24 and 52 after treatment
|
|
Change from baseline in alveolar volume (VA)
Zeitfenster: Week 12, 24 and 52 after treatment
|
VA is assessed by measured values, measured/predicted ratio and corresponding area under curve (AUC).
|
Week 12, 24 and 52 after treatment
|
|
Change from baseline in forced expiratory volume in the first second (FEV1) post-bronchodilator
Zeitfenster: Week 12, 24 and 52 after treatment
|
FEV1 is assessed by measured value, measured/predicted ratio and corresponding area under curve (AUC).
|

|
Week 12, 24 and 52 after treatment
|
|
Change from baseline in St. George's Respiratory Questionnaire for COPD (SGRQ-C) score
Zeitfenster: Week 12, 24 and 52 after treatment
|
The St. George's Respiratory Questionnaire for COPD (SGRQ-C) is a validated disease-specific patient-reported outcome measure used to assess the impact of COPD on patients' health status and quality of life.
Total score, ranged from 0 to 100, is the sum of points from all items.
A higher value represents a worse outcome.
|
Week 12, 24 and 52 after treatment
|
|
Proportion of subjects with a ≥4-point improvement or worsening from baseline in SGRQ-C score
Zeitfenster: Week 12, 24 and 52 after treatment
|
Minimal clinically important difference for SGRQ is recognized as 4 points.
|
Week 12, 24 and 52 after treatment
|
|
Annualized rate of COPD exacerbations (AECOPD), adjusted for prior exacerbation history and baseline characteristics
Zeitfenster: Week 52 after treatment
|
The annualized rate of COPD exacerbations (AECOPD), adjusted for prior exacerbation history and baseline characteristics, represents the adjusted frequency of acute exacerbations of COPD over the assessment period.
|
Week 52 after treatment
|
|
Change from baseline in arterial blood gas parameters
Zeitfenster: Week 52 after treatment
|
The change from baseline in arterial blood gas parameters reflects changes in gas exchange function and respiratory status over the assessment period.
|
Week 52 after treatment
|
|
Change from baseline in HRCT images
Zeitfenster: Week 52 after treatment
|
HRCT images are quantitatively analyzed using dedicated software to measure emphysema volume (mL) and functional lung volume (mL).
|
Week 52 after treatment
|
|
Adverse Event
Zeitfenster: Hour 24, Week 12, 24 and 52 after treatment
|
An adverse event (AE) is any untoward medical occurrence in a subject who has received a study intervention, regardless of whether or not it is considered related to the intervention.
|
Hour 24, Week 12, 24 and 52 after treatment
