Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Change From Baseline to Week 104 in Trough Forced Expiratory Volume in 1 Second (FEV1)
Lasso di tempo: Baseline to Week 104
The analysis of the change from Baseline to Week 104 (last observation carried forward [LOCF]) in trough FEV1 is presented below.
Baseline to Week 104
Rate of Change From Baseline to Week 104 in 20th Percentile of Lung Density Voxels
Lasso di tempo: Baseline to Week 104
The analysis of the change from Baseline to Week 104 (LOCF) in the 20th percentile of lung density voxels (expressed in Hounsfield unit [HU] using quantitative HCRT) by visit and lung region is presented below.
Baseline to Week 104

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Percent Change From Baseline in Trough FEV1 From Baseline to Week 104
Lasso di tempo: Baseline to Week 104
The percent change for the pulmonary function tests (PFT) from baseline was calculated for each study week as follows: % change from baseline = ([value at Week X - value at baseline] /value at baseline) x 100.
Baseline to Week 104
Density Mask Score Based on Specified Thresholds Including -950 HU
Lasso di tempo: Baseline and Week 104
The density mask score is defined as the percentage of lung density voxels that lie below a specified threshold in the lung region of interest. The higher the percentage of the participant's lung density voxels that lie below a specified threshold, the higher the level of the participant's emphysema in the lung region under consideration. Changes in the density mask score was assessed using only a single density mask threshold of -950 HU.
Baseline and Week 104
Rate of Change in the 20th Percentile of Lung Density Voxels Expressed in HU Units for the Whole Lung (Whole Right + Whole Left) From Baseline to Week 104
Lasso di tempo: Baseline to Week 104
The rate of change in lung density was calculated as the change in the 20th percentile of lung density voxels divided by the duration between the dates of measurement (month or year) where applicable. For example, if HRCT measurements are available over a span of 2 years, the annual rate of change was calculated as the difference over the 2 years divided by 2, where years between scans is given by years= floor(data of last scan - date of first scan + 1)/365.25.
Baseline to Week 104
Observed Rate of Change in Emphysema From Baseline to Week 104
Lasso di tempo: Baseline to Week 104
The level of emphysema (g/L) within in a lung region is defined as the value of the selected percentile (10th, 15th, or 20th) in HU + 1000. The rate of change in the emphysema from baseline was calculated as the change in the level of emphysema from baseline to the specified visit divided by the time in years between the baseline and specified visit (i.e., [date of visit - date of baseline visit + 1]/365.25).
Baseline to Week 104
Change From Baseline to Week 104 in Cumulative Frequency of HU
Lasso di tempo: Baseline and Week 104
The area under the curve (AUC) is defined as the cumulative voxel frequency in HU (ie, the value of the density mask denominator). Blood samples (4 mL) for pharmacokinetic analysis were collected for the determination of plasma OPC-6535 concentrations at Predose on Day 1 and Weeks 26, 52, 78 and 104.
Baseline and Week 104
Change From Baseline to Week 104 in Computed Tomography (CT) - Derived Lung Volumes (Total Lung Capacity [TLC] and Residual Volume [RV])
Lasso di tempo: Baseline to Week 104
Change from baseline in CT-derived lung volumes TLC and RV are presented in the below outcome data table.
Baseline to Week 104
Change From Baseline to Week 104 in Trough RV/TLC
Lasso di tempo: Baseline to Week 104
Change from Baseline in Trough RV/TLC is presented in the below outcome data table.
Baseline to Week 104
Change From Baseline to Week 104 in Trough Inspiratory Capacity
Lasso di tempo: Baseline toWeek 104
Change from Baseline in Trough Inspiratory Capacity is presented in the below outcome data table.
Baseline toWeek 104
Change From Baseline to Week 104 in Trough Functional Residual Capacity (FRCpleth)
Lasso di tempo: Baseline to Week 104
Change from baseline in trough FRCpleth is presented in the below outcome data table.
Baseline to Week 104
Change From Baseline to Week 104 in Carbon Monoxide Diffusion Capacity (DLco)
Lasso di tempo: Baseline to Week 104
Change from Baseline in DLco is presented in the below outcome data table.
Baseline to Week 104
Change From Baseline to Week 104 in Mean Specific Airway Resistance (sRaw) and Specific Conductance (sGaw)
Lasso di tempo: Baseline to Week 104
Change from baseline in sRaw and sGaw is presented in the below outcome data table.
Baseline to Week 104
Change From Baseline to Week 104 in 7-day Average Total Symptom Score of Dyspnea, Cough and Sputum
Lasso di tempo: Baseline to Week 104
Participants used the Breathlessness, Cough, and Sputum Scale (BCSS) as the diary to daily monitor and rate their symptoms of difficulty breathing, cough, and sputum. The scale allows patients to rate each symptom on a scale of 0 (no difficultly for breathing and sputum, or unaware of coughing) to 4 (an almost constant problem for breathing and sputum, or almost constant for cough).
Baseline to Week 104
Change From Baseline to Week 104 in 7-day Mean Number of Actuations of Rescue Medications
Lasso di tempo: Baseline to Week 104
Participants recorded rescue medication use (albuterol and/or ipratropium bromide) in a rescue medication log.
Baseline to Week 104
Percentage of Participants With COPD Exacerbations by Group at Week 104
Lasso di tempo: Baseline and Week 104
For the COPD exacerbations, baseline is defined as Randomization (Day 1). COPD exacerbations, defined as an acute worsening of COPD symptoms, were classified as being in one of 3 levels: Level I (can by self-managed by the participant); Level II (requires a physician visit), or Level III (requires a hospital visit).
Baseline and Week 104
Percentage of Participants Experiencing a COPD Exacerbation (Level 2 or Higher)
Lasso di tempo: Baseline and Week 104
Percentage of participants experiencing a COPD exacerbation in a level 2 or higher are presented in the below outcome data table.
