A 24 Week Efficacy Study of Inhaled Umeclidinium (UMEC) in Patients of Chronic Obstructive Pulmonary Disease (COPD) Using a Novel Dry Powder Inhaler (NDPI)

The Baseline Dyspnea Index (BDI) is used to measure the severity of dyspnea in participants at Baseline . The TDI measures changes in dyspnea severity from Baseline, as established by the BDI. TDI is formed of 3 individual scales that assess change in functional impairment, change in magnitude of task and change in magnitude of effort. The instrument is scored on a 7-point scale from -3 (major deterioration) to +3 (major improvement) for each category. Total scores (3 categories) range from -9 to +9 with lower scores indicating more deterioration in the severity of dyspnoea. A change of >=1 units is considered to be the minimum clinically important difference (MCID) for the TDI.

FEV1 is a measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. Weighted mean FEV1 was calculated over the nominal 0 to 6 hour post dose period. Values from post-dose assessments which were actually before the time of dosing were excluded from the calculation. The 0 hour value is the average value obtained 30 minutes and 5 minutes pre-dose, and both the 0 hour and 6 hour values must be present for a 0- to 6 hour weighted mean to be calculated. The 0 -to 6 hour weighted mean was derived by calculating the area under the FEV1 curve over the nominal time points of 0 hour, 15 and 30 minutes, 1, 3 and 6 hours, using the trapezoidal rule, and then dividing by the actual time between dosing and the 6 hour assessment. Baseline value for FEV1 was calculated from the values measured 30 minutes and 5 minutes pre-dose on Day 1. Change from Baseline was calculated by subtracting the value on-treatment from the Baseline value.

AE is any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An SAE is any untoward medical occurrence that, at any dose results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or is a congenital anomaly/birth defect or is medically significant or is associated with liver injury and impaired liver function.

Vital signs (SBP and DBP) were obtained after participants had rested for approximately 5 minutes and before performing electrocardiogram (ECG) and spirometry testing. A single set of values was obtained. Baseline was the most recent recorded value before dosing on Day 1 at schedule visit. Change from Baseline was calculated by subtracting the value on-treatment from the Baseline value. Anytime post-Baseline values have been presented for SBP and DBP respectively.

Vital sign pulse rate was obtained after participants had rested for approximately 5 minutes and before performing electrocardiogram (ECG) and spirometry testing. A single set of values was obtained. Baseline was the most recent recorded value before dosing on Day 1 at schedule visit. Change from Baseline was calculated by subtracting the value on-treatment from the Baseline value. Anytime post-Baseline values have been presented for pulse rate.

A 12-lead ECG measurement was obtained after measurement of vital signs and before spirometry testing. Participants should be placed in the supine position for the ECG measurements. Any ECG abnormality recorded by a participant after the start of study treatment was included in the any-time post-Baseline record of all ECG abnormalities. Partcipants with abnormal ECG interpretation have been presented.

Hematology parameters included basophils (normal range 0 to 0.2 giga cells/Liter), eosinophils (0.05 to 0.55 giga cells/Liter), hematocrit (0.36 to 0.49 percentage of red blood cells in blood), hemoglobin (118 to 168 gram/Liter), lymphocytes (0.85 to 4.1 giga cells/Liter), monocytes (0.2 to 1.1 giga cells/Liter), platelet count (PC)(130 to 400 giga cells/Liter), neutrophils (1.8 to 8 giga cells/Liter), total neutrophils (TN) (1.8 to 8 giga cells/Liter), white blood cell [WBC] count (3.8 to 10.8 giga cells/Liter). Only categories with non-zero (high and low) values at any time post Baseline have been presented.

Clinical chemistry parameters assessed included albumin (normal range 32 to 50 grams/Liter [G/L]), alkaline phosphatase (20 to 125 international units/Liter [IU/L]), alanine aminotransferase [ALT] (0 to 48 IU/L), aspartate aminotransferase [AST] (0 to 55 IU/L), direct bilirubin (0 to 6 micromoles/liter [umol/l]), indirect bilirubin (0 to 22 umol/l), total bilirubin (0 to 22 umol/l), calcium (2.12 to 2.56 milimoles/liter [mmol/l]), chloride (95 to 108 mmol/l), carbon dioxide [CO2] content/bicarbonate (20 to 32 mmol/l), creatinine (67.2 to 129.1 umol/l), creatinine phosphokinase [CPK] (0 to 235 IU/L), gamma glutamyl transferase [GGT] (0 to75 IU/L), glucose (3.9 to 6.9 mmol/l), phosphorus (0.7 to 1.4 mmol/l), potassium (3.5 to 5.3 mmol/l), protein total (58 to 81 G/L), sodium (135 to 146 mmol/l), urea nitrogen (2.5 to 10.5 mmol/l), uric acid (240 to 510 umol/l). Only categories with non-zero (high and low) values at any time post Baseline have been presented.

Urinalysis parameters assessed were urine ketones, urine bilirubin, urine glucose, urine leukocyte esterase test for detecting WBC and urine protein. In this dipstick test, the level of bilirubin, glucose, leukocyte esterase and protein in urine samples was recorded as negative, trace, 1+, 2+, and 3+ (the plus sign increases with a higher level of bilirubin, glucose, leukocyte esterase, or proteins in the urine: 1+=slightly positive, 2+=positive, 3+=high positive). Urine samples were collected for the measurement of urinalysis parameters by dipstick method up to Day 168 (Visit 8). Only categories with significant values have been presented. Only those participants with data available at the indicated time point were analyzed.

Urinary pH measurement is a routine part of urinalysis. Urine pH is an acid-base measurement. pH is measured on a numeric scale ranging from 0 to 14; values on the scale refer to the degree of alkalinity or acidity. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Normal urine has a slightly acid pH (5.0 to 6.0). Urine samples were collected for the measurement of urine pH up to Day 168 (Visit 8). Only categories with significant values have been presented. Only those participants with data available at the indicated time point were analyzed.

The SGRQ is designed to measure health-related quality of life (HRQoL) in participants with diseases of airway obstruction with the use of 76 items grouped into three domains: symptoms, activity and impact. The questions are designed to be self-completed by the participant based on recall of the past 4 weeks. Domain score =sum of the weighted scores for the non-missing items within each domain/maximum possible score for those non-missing items x 100. The SGRQ total score= sum of the weighted scores from all 76 items /maximum possible score for the SGRQ x100. Scores range from 0, representing the best possible health status, to 100, representing the worst possible health status. A decrease in score indicates an improvement in HRQoL whereas increase indicates deterioration in HRQoL. Baseline was the most recent recorded value before dosing on Day 1 at schedule visit. Change from Baseline was calculated by subtracting the value on-treatment from the Baseline value.

The CAT is an 8-item, participant-completed instrument that covers symptoms such as cough, phlegm, chest tightness and breathlessness, and disease impacts including physical activity, confidence, sleep and energy. The CAT asks participant to score each item according to their current experience; there is no specific recall period. Items are scored on a 6-point response scale, with a score of 0 representing the participants are not experiencing the symptom/impact at all and a score of 5 representing a maximal symptom or impact. All items have equal weighting and so the total score is simply the sum of all scores and can range from 0 to a maximum of 40, with higher scores indicating a worse health state while a decrease in score indicates an improvement in health status. Baseline was the most recent recorded value before dosing on Day 1 at schedule visit. Change from Baseline was calculated by subtracting the value on-treatment from the Baseline value.

The total number of participants with visits for each type of healthcare contact ( office/practice visits, urgent care/outpatient clinic visits, emergency room visits and the intensive care visit and general wards visit have been presented.

The total number of days requiring admission to intensive care unit and general ward have been presented.
