GW815SF For Chronic Obstructive Pulmonary Disease (Chronic Bronchitis, Emphysema)

Hematology parameters: Red blood cells (RBC), Hemoglobin (Hb), Hematocrit, Platelet count (PC), White blood cells (WBC), Basophils, Eosinophils, Neutrophils, Lymphocytes and Monocytes were presented as the outliers from the normal range as > upper limit and < lower limit. Only number of participants with hematology values outside normal range were presented.

Clinical chemistry parameters: Total bilirubin (TB), Alkaline phosphatase (Al-P), Alanine aminotransferase (ALT), Asparate aminotransferase (AST), Gamma-glutamyl transpeptidase (GTP), Lactate dehydrogenase (LDH), Total cholesterol (TC), Glucose, Creatinine, Blood urea nitrogen (BUN), Uric acid (UA), Sodium (Na), Potassium (K), Chloride (Cl) and Calcium (Ca) were presented as the outliers from the normal range as > upper limit and < lower limit. Only number of participants with clinical chemistry values outside normal range were presented.

Urinalysis parameters: Urine protein, Glucose and Urobilinogen were presented as shift from Baseline. Only number of participants with urinalysis values more than Baseline values were presented. The plus sign increases with a higher level of glucose and proteins in the urine: 1+: slightly positive, 2+: positive, 3+: high positive and 4+: strongly positive.

On each assessment day at Week 24 and 52, adrenal cortical function tests were performed between 8:00-10:00 in the morning. Additional measurements were taken at follow up visit, if the measurements made at Week 52 revealed any abnormalities of clinical significance. Blood samples were taken from participants at rest before undergoing spirometry. Baseline value was the measurement taken at the start of run-in or the treatment period. Change from Baseline was any post Baseline value minus value at Baseline.

Additional measurements were taken at follow up visit, if the measurements made at Week 52 revealed any abnormalities of clinical significance. Blood samples were taken from participants at rest before undergoing spirometry.

Systolic and diastolic BP was measured in sitting position. Baseline value was the measurement taken at the start of run-in or the treatment period. Change from Baseline was any post Baseline value minus value at Baseline.

Pulse rate was measured in sitting position. Baseline value was the measurement taken at the start of run-in or the treatment period. Change from Baseline was any post Baseline value minus value at Baseline.

Oropharyngeal examination was performed in participants with suspected oral infection (candidiasis).

On each assessment day at Week 24, 52 and follow up 12-lead ECG was performed. Additional measurements were taken at follow up visit, if the measurements made at Week 52 revealed any abnormalities of clinical significance.

On each assessment day at Week 52 and follow up, lumber (L1-L4) BMD was determined with a BMD meter by the dual energy X-ray absorption (DEXA) method. Baseline value was the measurement taken during run-in period. Change from Baseline was any value post Baseline minus value at Baseline.

Body weight was measured during run-in period, at Week 24 and 52.

On each assessment day at Week 24, 52 and follow up, ophthalmological examinations (vision, cornea, lens, intraocular pressure, fundus oculi) were performed to determine the presence or absence of glaucoma and cataract.

PEF was the maximum speed of expiration measured using spirometer. A participant took rest just before the measurement. At each time of measurement, a participant expired for at least 6 seconds wherever possible. At each time of measurement, at least 3 readings were obtained, and three readings which were obtained in an appropriate manner were stored. Baseline value was the value measured at visit 2. However, when the value at Visit 2 was missing, the value at Visit 1 was used as Baseline. Change from Baseline was any post Baseline value minus Baseline value.

FVC was the amount of air which can be forcibly exhaled from the lungs after taking the deepest breath possible measured using spirometer. A participant took rest just before the measurement. At each time of measurement, a participant expired for at least 6 seconds wherever possible. At each time of measurement, at least 3 readings were obtained, and three readings which were obtained in an appropriate manner were stored. Baseline value was the value measured at visit 2. However, when the value at Visit 2 was missing, the value at Visit 1 was used as Baseline. Change from Baseline was any post Baseline value minus Baseline value.

V25 and V 50 were measured using spirometer. A participant took rest just before the measurement. At each time of measurement, a participant expired for at least 6 seconds wherever possible. At each time of measurement, at least 3 readings were obtained, and three readings which were obtained in an appropriate manner were stored. Baseline value was the value measured at visit 2. However, when the value at Visit 2 was missing, the value at Visit 1 was used as baseline. Change from Baseline was any post Baseline value minus Baseline value.

Rescue medication (salbutamol sulfate aerosol provided as an investigational product) was issued to a participant and, when necessary, a spacer at the start of the run-in period. At each time of entry in the Chronic Obstructive Pulmonary Disease (COPD) diary, a participant recorded the number of occasions of rescue medication inhaled in the previous 24 hours in the COPD diary. Baseline was mean value of the consecutive 7 days just before Visit 2. Change from Baseline was any post Baseline value minus Baseline value.

A participant recorded scores on the scale of 0 to 4 for breathlessness and nighttime awakenings, where 0 indicated no symptoms and 4 indicated severe symptoms; on the scale of 0 to 3 for cough and sputum production, where 0 indicated no symptoms and 3 indicated severe symptoms, in the 24 hours prior to each entry in the COPD diary. Baseline was mean value of the consecutive 7 days just before Visit2. Change from Baseline was any post Baseline value minus Baseline value.

An exacerbation was defined as worsening of the participant's symptoms of cough, sputum production and breathlessness requiring a change in medication. When a moderate or severe COPD exacerbation was observed, details (date of onset, outcome, date of resolution/death, severity, medications provided for treatment, whether the COPD exacerbation required hospitalization, whether the COPD exacerbation required participant withdrawal from the study) were recorded.

For analysis of pharmacokinetic (PK) parameters for FP, blood samples were taken just before dosing (within one hour prior to dosing), 30, 45 minutes, 1, 2, 3, 4, 6, 8 and 12 hours after dosing to determine plasma drug concentrations. The investigational product was taken in fasting condition just before each blood sampling. Parameters were calculated by a model-independent method with the plasma concentration-time profile data in individual participants.

For analysis of PK parameters for salmeterol, blood samples were taken just before dosing (within one hour prior to dosing), 5, 15, 30, 45 minutes, 1, 2, 3 and 4 hours after dosing to determine plasma drug concentrations. The investigational product was taken in fasting condition just before each blood sampling. Parameters were calculated by a model-independent method with the plasma concentration-time profile data in individual participants.
