An AE was defined as any untoward medical occurrence (MO) in a participant temporally associated with the use of a medicinal product (MP), whether or not considered related to the MP and can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with its use. The SAE was any untoward MO that, at any dose, results in death, life threatening, persistent or significant disability/incapacity, results in or prolongs inpatient hospitalization, congenital abnormality or birth defect, that may not be immediately life-threatening or result in death or hospitalization but may jeopardize the participant or may require medical or surgical intervention to prevent one of the other outcomes listed in this definition.

Blood pressure was measured subsequent to 12 lead electrocardiogram (ECG). Baseline was defined as the mean of the three planned pre-dose measurements. It was assessed on Baseline (triplicate), 15, 30 minutes, 1.5, 4, 8 and 24 hours on Day 1 and 7.

Heart rate was measured subsequent to 12 lead ECG. Baseline was defined as the mean of the three planned pre-dose measurements. It was assessed on Baseline (triplicate), 15, 30 minutes, 1.5, 4, 8 and 24 hours on Day 1 and 7.

Blood pressure was measured subsequent to 12 lead ECG. Baseline was defined as the mean of the three planned pre-dose measurements. It was assessed on pre-dose, 15, 30 minutes, 1.5 and 4 hours on Day 1 and 7. Data for adjusted mean is presented as least square mean.

Single measurements were taken at all time points. The pre-dose values were classed as Baseline. Data for number of participants with normal, abnormal not clinically significant and abnormal clinically significant is presented. It was assessed on Baseline (triplicate), 15, 30 minutes, 1.5, 4, 8 and 24 hours on Day 1 and 7.

It was assessed on 1, 2, 4, 9, 12 and 24 hours on Days 1 and 7. Also on Day 7, it was measured on 0 hour (Baseline). At all time points 3 measurements were taken and formal statistical analysis was carried out on the derived maximum readings. Data for adjusted mean is presented as least square mean.

Inhaled salbutamol was used as a rescue medication. Participants were required to keep a diary of their rescue medication (total number of salbutamol doses taken) over the entire 7-day treatment period. Diaries were reviewed by the Investigator when participants were admitted to the unit on Days 1, 2, 7 and 8.

Clinical chemistry parameters included urea, potassium, aspartate aminotransferase (AST), total bilirubin, creatinine, creatine kinase, chloride, alanine aminotransferase (ALT), uric acid, glucose, gamma glutamyltransferase (GGT), albumin, sodium, phosphorus inorganic, calcium, alkaline phosphatase (ALP) and total protein. It was assessed on Day 1 (pre-dose, 24 hours) and Day 7 (pre-dose, 24 hours). Data for parameters with above and below the potential clinical concern (PCI) is provided.

Hematology parameters included platelet count, red blood cell (RBC) count, mean corpuscular volume (MCV), total neutrophils, white blood cell (WBC) count (absolute), mean corpuscular hemoglobin (MCH), lymphocytes, mean corpuscular hemoglobin concentration (MCHC), monocytes, hemoglobin, eosinophils, hematocrit and basophils. It was assessed on Day 1 (pre-dose, 24 hours) and Day 7 (pre-dose, 24 hours). Data for parameters with above and below the PCI is provided.

Urinalysis parameters included protein, blood, ketones, glucose, bilirubin, urobilinogen, leukocyte esterase, specific gravity, nitrites and pH. Sediment microscopy was performed only on urine samples showing an abnormality on the dipstick. Microscopy was performed for: WBC, RBC, hyaline casts, granular casts and cellular casts. It was assessed on Day 1 (pre-dose, 24 hours) and Day 7 (pre-dose, 24 hours).

Holter monitors were switched on immediately prior to dosing (up to 15mins pre-dose) so as to capture Holter ECG data from the 24 hour period following dosing. It was assessed on Day 1 and 7.
