Phase 3
Completed
Conditions
Chronic Obstructive Pulmonary Disease
Interventions
Drug: Budesonide/formoterol (Symbicort Turbuhaler)
Registration Number

Pre-dose Forced Vital Capacity (FVC)Before randomization, 0, 4, 8 and 12 weeks after randomization

The ratio, expressed as percentage, of the geometric mean of available data for Weeks 0, 4, 8 and 12 to the baseline for each treatment group

1 Hour Post-dose Forced Vital Capacity (FVC)Before randomization, 0, 4, 8 and 12 weeks after randomization

The ratio, expressed as percentage, of the geometric mean of available data for Weeks 0, 4, 8 and 12 to the baseline for each treatment group

Percentage of Participants With ExacerbationsDaily during 12-week randomization treatment

A Chronic Obstructive Pulmonary Disease (COPD) exacerbation was defined as worsening in COPD symptoms requiring treatment with either a course of systemic steroid or hospitalisation. The percentage of participants who had experienced COPD exacerbation at the end of the study for each treatment group.

Number of Chronic Obstructive Pulmonary Disease (COPD) ExacerbationDaily during 12-week randomization treatment

A Chronic Obstructive Pulmonary Disease (COPD) exacerbation was defined as worsening in COPD symptoms requiring treatment with either a course of systemic steroid or hospitalisation. Number of COPD exacerbation during 12-week randomization treatment

Morning Peak Expiratory Flow(PEF)Daily during run-in period and daily during 12-week randomization treatment

The change from Run-in period average to Treatment period average for each treatment group

Evening Peak Expiratory Flow (PEF)Daily during run-in period and daily during 12-week randomization treatment

The change from Run-in period average to Treatment period average for each treatment group

Total Number of Day With ExacerbationDaily during 12-week randomization treatment

Total number of days with COPD exacerbation for each treatment group

Morning Forced Expiratory Volume in One Second (FEV1)Daily during run-in period and daily during 12-week randomization treatment

The change from Run-in period average to Treatment period average for each treatment group

Evening Forced Expiratory Volume in One Second (FEV1)Daily during run-in period and daily during 12-week randomization treatment

The change from Run-in period average to Treatment period average for each treatment group

Night-time Awakening Due to Chronic Obstructive Pulmonary Disease (COPD) SymptomsDaily during run-in period and daily during 12-week randomization treatment

Scored 0 to 1 (0 = no awakening and 1 = awakening). The change from Run-in period average to Treatment period average for each treatment group

Breathlessness Due to Chronic Obstructive Pulmonary Disease (COPD) SymptomsDaily during run-in period and daily during 12-week randomization treatment

There are 5 alternatives (scored 0 to 4, with 4 being the most severe condition). The change from Run-in period average to Treatment period average for each treatment group

Cough Due to Chronic Obstructive Pulmonary Disease (COPD) SymptomsDaily during run-in period and daily during 12-week randomization treatment

There are 5 alternatives (scored 0 to 4, with 4 being the most severe condition). The change from Run-in period average to Treatment period average for each treatment group

Total Chronic Obstructive Pulmonary Disease (COPD) Symptom ScoreDaily during run-in period and daily during 12-week randomization treatment

The Total COPD Symptom score is the sum of the measures night-time awakening, breathlessness and cough, ranges from 0 to 12 with 12 being the most severe. The change from Run-in period average to Treatment period average for each treatment group.

Use of Rescue MedicationDaily during run-in period and daily during 12-week randomization treatment

The change from Run-in period average to Treatment period average for each treatment group.

St George's Respiratory Questionnaire (SGRQ) Total ScoreDaily during run-in period and daily during 12-week randomization treatment

The change from Run-in period average to Treatment period average for each treatment group. The SGRQ ranges from 0 (no impairment of quality of life) to 100 (highest impairment of quality of life).
