MeasureTime frameDescription
Number of COPD-Related Deaths During the Study - ITT PopulationDays 1 to 180Cumulative incidences of COPD-related deaths until Day 30/60/90/120/150/180 were obtained.
Change From Baseline in FEV1 on Days 3, 10, and 14 - ITT PopulationDays 3, 10, and 14FEV1 data were recorded daily from Days 1 to 7, and Days 10 and 14 of the study using a computer-operated spirometer. Analysis was based on a linear MMRM with Change from Baseline in parameter as outcome; including treatment, visit, treatment by visit interaction, severity of airflow limitation at Baseline, blood eosinophils (%) at Baseline, time from start of current COPD exacerbation to first study treatment dosing, presence of cardiovascular comorbidities at Screening and COPD exacerbation treatment at Screening as fixed effects, and Baseline value and Baseline by visit interaction as covariates. Baseline was defined as the last non-missing value collected before the first study treatment administration, including unscheduled assessments.
Normalization Evaluation of FEV1 Over Time (Days 1 to 7, Days 10 and 14, and Weeks 8, 12 and 26) Compared With the Most Recent Test Performed Within the Last 12 Months Outside an Exacerbation - ITT PopulationBaseline, Days 1 to 7, Days 10 and 14, Week 8, Week 12 and Week 26FEV1 data were recorded daily from Days 1 to 7 and on Days 10 and 14 and Weeks 8, 12, and 26 of the study using a computer-operated spirometer. FEV1 normalization was achieved if FEV1 returned to a value ≥ 89% of the most recent FEV1 value measured within the last 12 months outside an exacerbation (pre-study FEV1 value). Baseline was defined as the last non-missing value collected before the first study treatment administration, including unscheduled assessments. Percentages (%) were based on number of non-missing values as denominator.
Normalization Evaluation of FEV1/FVC Over Time (Days 1 to 7, Days 10 and 14, and Weeks 8, 12 and 26) Compared With the Most Recent Test Performed Within the Last 12 Months Outside an Exacerbation - ITT PopulationBaseline to Week 26FEV1 and FVC were recorded daily from Days 1 to 7 and on Days 10 and 14 and Weeks 8, 12, and 26 of the study using a computer-operated spirometer. FEV1/FVC normalization was achieved if FEV1/FVC returned to a value ≥ 89% of the most recent FEV1/FVC value measured within the last 12 months outside an exacerbation (pre-study FEV1/FVC value). Baseline was defined as the last non-missing value collected before the first study treatment administration, including unscheduled assessments.
Time to Improvement of 100 mL in FEV1 Over Time - ITT PopulationBaseline to Week 26Time to improvement of 100 mL in FEV1 was defined as time (in days) from initiation of study treatment until the change in FEV1 was ≥ +100 mL.
Area Under the Curve (AUC) of FEV1 Over Time - ITT PopulationDay 1 to Day 14AUC was calculated according to the trapezoidal rule. The trapezoidal rule is a numerical method to be used to approximate the integral or the area under a curve. Using trapezoidal rule to approximate the area under a curve first involves dividing the area into a number of strips of equal width. Then, approximating the area of each strip by the area of the trapezium formed when the upper end is replaced by a chord. The sum of these approximations gives the final numerical result of the AUC.
Normalization of Respiratory Rate (RR) Over Time During Acute Exacerbation Phase - ITT PopulationDay 1 to Day 14RR was normalized when it returned to a baseline plateau level achieved after the acute COPD exacerbation during the Stabilization Phase. Baseline was defined as the last non-missing value collected before the first study treatment administration, including unscheduled assessments.
Change From Baseline in RR on Days 3, 7, 10 and 14 - ITT PopulationDays 1 to 14RR (breaths/min) was recorded over time during the acute exacerbation phase.
Time to Recovery Based on EXACT-PRO Total Score During the Acute Exacerbation Phase - ITT PopulationDays 1 to 29Recovery based on EXACT-PRO total score was defined as the first day in which a participant experiences a persistent, sustained improvement in their condition over the observed period (Day 1 to Day 29). Improvement had to be present for 7 consecutive days. The first day of the 7-day period was designated as the first day of Recovery. An EXACT total score was computed for each day of diary collection.
Standardized AUC of EXACT-PRO Rolling Average Over Time During Acute Exacerbation Phase - ITT PopulationDays 1 to 29The standardized AUC of the EXACT-PRO were calculated from Day (a) to Day (b) using the trapezoidal rule.
Standardized AUC of EXACT-PRO (Breathlessness) Rolling Average Over Time During Acute Exacerbation Phase - ITT PopulationDays 1 to 29Information regarding the participant's condition can be obtained through 3 domain scores embedded within the EXACT measure: Breathlessness, Cough & Sputum, and Chest Symptoms. These scores also range from 0 to 100 with higher scores indicating more severe symptoms.The standardized AUC of the EXACT-PRO were calculated from Day (a) to Day (b) using the trapezoidal rule.
Rate of Positively Adjudicated Moderate/Severe COPD Exacerbations - ITT PopulationDay 1 to End of Study (Day 180)Follow-up time per participant (years) was defined as (date of last contact - date of first study drug administration + 1)/ 365.25. Total follow-up time (years) = sum of individual participant follow-up times. Rate was calculated as total number of positively adjudicated exacerbations divided by the total follow-up time in years of the treatment group.
Time to Next Positively Adjudicated Moderate/Severe COPD Exacerbation- ITT PopulationDay 1 to Day 180Time to next positively adjudicated moderate/severe COPD exacerbation (in days) was defined as date when first moderate/severe COPD exacerbation symptoms started - date when current COPD exacerbation symptoms stopped, where COPD exacerbations experienced during the study were positively adjudicated by the Independent Adjudication Committee. Time to next positively adjudicated COPD exacerbation was presented in 25th percentile (95% confidence interval) as medians were not evaluable.
Time From Hospitalization Admission Until the Participant Is Medically Ready for Discharge (Current COPD) - ITT PopulationDay 1 to Day 30Time from hospitalization admission until the participant is medically ready for discharge (in days) = Date participant was medically ready for discharge from hospital - Date of hospitalization admission. Date of hospitalization admission' and 'Date participant was medically ready for discharge from hospital' were recorded on the 'Current COPD Exacerbation' form of the eCRF. Results were presented with 75th percentile (95% CI) due to the fact that 95% CI for the median was not evaluable.
Percentage of Days With Intake of COPD Rescue Therapy - ITT PopulationBaseline to Week 26Participants completed the EXACT-PRO starting from Day 1 and recorded rescue medication use and any occurrences of COPD once a day (evening) in the diary. The percentage of days with intake of rescue medications was evaluated on the basis of the information recorded daily by the participant on the diaries. A day was considered with intake of rescue medications if the answer to the question How many puffs of rescue medication did you take since last evening? was\> 0.
Time to Improvement Based on the EXAcerbations of Chronic Pulmonary Disease Tool-Patient Reported Outcome (EXACT-PRO) Total Score During the Acute Exacerbation Phase - ITT PopulationDays 1 to 29Improvement based on EXACT-PRO total score is defined as a decrease in the Rolling Average EXACT score ≥ 9 points from the previous day's maximum observed value during an event. The EXACT is a 14-item patient reported outcome (PRO) daily diary used to quantify and measure exacerbations of COPD. The health status of the participant is correlated to the global score, meaning a higher score corresponds to a more severe health status of the participant. An EXACT Total score is computed for each day of diary collection. The EXACT Total score is based on a logit scoring system with conversion to a 0 to 100 scale for ease of interpretation and use. The total score was used in the determination of exacerbation frequency, severity and duration of exacerbation. Specifically, changes in the total score were used to define onset and recovery from an exacerbation event and the magnitude of that event.

Normalization Evaluation of FEV1 Over Time (Days 1 to 7, Days 10 and 14, and Weeks 8, 12 and 26) Compared With the Most Recent Test Performed Within the Last 12 Months Outside an Exacerbation - ITT Population

FEV1 data were recorded daily from Days 1 to 7 and on Days 10 and 14 and Weeks 8, 12, and 26 of the study using a computer-operated spirometer. FEV1 normalization was achieved if FEV1 returned to a value ≥ 89% of the most recent FEV1 value measured within the last 12 months outside an exacerbation (pre-study FEV1 value). Baseline was defined as the last non-missing value collected before the first study treatment administration, including unscheduled assessments. Percentages (%) were based on number of non-missing values as denominator.

Time From Hospitalization Admission Until the Participant Is Medically Ready for Discharge (Current COPD) - ITT Population

Time from hospitalization admission until the participant is medically ready for discharge (in days) = Date participant was medically ready for discharge from hospital - Date of hospitalization admission. Date of hospitalization admission' and 'Date participant was medically ready for discharge from hospital' were recorded on the 'Current COPD Exacerbation' form of the eCRF. Results were presented with 75th percentile (95% CI) due to the fact that 95% CI for the median was not evaluable.

Time to Improvement Based on the EXAcerbations of Chronic Pulmonary Disease Tool-Patient Reported Outcome (EXACT-PRO) Total Score During the Acute Exacerbation Phase - ITT Population

Improvement based on EXACT-PRO total score is defined as a decrease in the Rolling Average EXACT score ≥ 9 points from the previous day's maximum observed value during an event. The EXACT is a 14-item patient reported outcome (PRO) daily diary used to quantify and measure exacerbations of COPD. The health status of the participant is correlated to the global score, meaning a higher score corresponds to a more severe health status of the participant. An EXACT Total score is computed for each day of diary collection. The EXACT Total score is based on a logit scoring system with conversion to a 0 to 100 scale for ease of interpretation and use. The total score was used in the determination of exacerbation frequency, severity and duration of exacerbation. Specifically, changes in the total score were used to define onset and recovery from an exacerbation event and the magnitude of that event.
