Overview
Brief Summary
The study drug which is an inhaled bronchodilator (lung airway relaxant)has been given to both healthy volunteers and to COPD patients before. This study will assess a new formulation of GSK573719. Many drugs are known to deteriorate over time. To make the study medicine less likely to deteriorate in its container, it is mixed with an inactive substance that helps to to maintain the quality of the study medicine. Previous studies have looked at GSK573719 with another inactive substance called Cellobiose Octaacetate (COA). This study will be looking at a new formulation of GSK573719 using Magnesium Stearate (MgSt) as the inactive substance. MgSt itself is not a medicine but is approved as a food ingredient and has also has been approved to be used in a number of marketed medical inhalers. The purpose of this study is to assess the safety and tolerability of compound GSK573719 with Magnesium Stearate for once-daily treatment of COPD(Chronic Obstructive Pulmonary Disease). This drug will be given to 2 groups of 12 people for 7 days. Group 1 will receive 250mcg or placebo and group 2 will receive 1000mcg or placebo. Group 2 will not be dosed until at least 6 people have completed dosing in group 1 without any significant safety concerns. The following safety measures will be assessed including: ECGs, heart rate, blood pressure, blood samples for safety labs, lung function and 24 hour monitoring of the heart. We will also take blood and urine samples to measure medication levels in the body.
GlaxoSmithKline will be funding the research and it will be recruiting at Synexus in 7 of their centres in the UK.

Outcomes
Primary Outcomes
Number of Participants With Any On-treatment Adverse Event (AE) or Any On-treatment Serious Adverse Event (SAE)
Time Frame: From start of treatment to study day 12
An AE is defined as any untoward medical occurrence in a participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An on-treatment adverse event is defined as an event that occurred between the start of investigational product and follow-up contact. Refer to the general SAE/non-serious AE module for a complete list of AEs reported in the study. An SAE is defined as 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.
Maximum and Weighted Mean (0-4 Hour) Heart Rate at Days 1 and 7
Time Frame: Day 1 and Day 7
Maximum heart rate (Max HR) and weighted mean (WM) from 0-4 hour on Days 1 and 7 were derived. Max HR (0-4 h) is defined as the maximum heart rate attained within 0-4 h. The weighted mean HR (0-4 h) was derived by calculating the area under the curve, and then dividing the value by the relevant time interval. Each of the maximum and weighted mean (0-4h) endpoints for heart rate, was statistically analyzed using a mixed effects model. The terms treatment, baseline, day and any relevant interactions were considered in the model. Least squares means are adjusted for treatment, Baseline, day, treatment by Baseline and Baseline by day interaction, where Baseline is defined as the mean of the three pre-dose assessments.
Mean Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) on Days 1 and 7
Time Frame: Day 1 (pre-dose and 15 minutes [min], 45 min, 1.5 hours [hr], 4 hr, and 8 hr post-dose) and Day 7 (pre-dose and 15 min, 45 min, 1.5 hr, 4 hr, 8 hr, and 24 hr post-dose)
Blood pressure was measured in a semi-recumbent position at approximately 45 degrees after the participant was kept at rest for at least 5 minutes. SBP and DBP were obtained at pre-dose and 15 min, 45 min, 1.5 hr, 4 hr, and 8 hr post-dose (PD) on Day 1 and at pre-dose and 15 min, 45 min, 1.5 hr, 4 hr, 8 hr, and 24 hr PD on Day 7.
Mean Heart Rate (HR) on Days 1 and 7
Time Frame: Day 1 (pre-dose and 15 minutes [min], 45 min, 1.5 hours [hr], 4 hr, and 8 hr post-dose) and Day 7 (pre-dose and 15 min, 45 min, 1.5 hr, 4 hr, 8 hr, and 24 hr post-dose)
HR was measured in a semi-recumbent position at approximately 45 degrees after the participant was kept at rest for at least 5 minutes. HR was obtained at pre-dose and 15 min, 45 min, 1.5 hr, 4 hr, and 8 hr post-dose (PD) on Day 1 and at pre-dose and 15 min, 45 min, 1.5 hr, 4 hr, 8 hr, and 24 hr PD on Day 7.

Number of Participants With the Indicated 12-lead Electrocardiogram (ECG) Values on Days 1 and 7
Time Frame: Day 1 (pre-dose and 15 min, 45 min, 1.5 hr, 4 hr, and 8 hr post-dose) and Day 7 (pre-dose and 15 min, 45 min, 1.5 hr, 4 hr, 8 hr, and 24 hr)
The number of participants with normal (NL), abnormal not clinically significant (Abn NCS), and abnormal clinically significant (Abn CS) ECG findings, as well as those with unavailable results (NA) at pre-dose (PD1, PD2, PD3), and 15 min, 45 min, 1.5 hr, 4 hr, and 8 hr post-dose (PD) on Day 1 and at pre-dose (PD1, PD2, PD3), and 15 min, 45 min, 1.5 hr, 4 hr, 8 hr, and 24 hr post-dose on Day 7 are reported. The following are of potential clinical importance: absolute QTc interval \>450 milliseconds (msec); increase from Baseline QTc \>60 msec; PR interval \<110 and \>220 msec; QRS interval \<75 and \>110 msec. Clinical significance was based on the medical and scientific judgement of the investigator or qualified designee.
Basophil, Eosinophil, Lymphocyte, Monocyte, Total Neutrophil (ANC: Absolute Neutrophil Count), Platelet, and White Blood Cell (WBC) Count Values on Day 1 and Day 7
Time Frame: Day 1 and Day 7
Blood samples were collected for the measurement of basophils, eosinophils, lymphocytes, monocytes, total neutrophils (ANC), platelets, and white blood cell (WBC) count pre-dose on Day 1 and Day 7.
Number of Participants With Abnormal 24-hour Holter Findings at Screening and Day 7
Time Frame: Screening and Day 7
Twenty-four hour Holter ECG values were obtained at Screening and on Day 7. During the Screening procedure and study, standard Holter monitors were used (in order to exclude participants with underlying cardiac arrhythmogenicity). During the treatment periods, Holter monitors were only switched on immediately prior to dosing (up to 15 minutes pre-dose) so as to capture Holter ECG data from the 24 hour period following dosing. The following summary data were transcribed into the Case Report Form: Maximum and mean (0 to24 hour) heart rate; normal and aberrant beats and arrhythmias. Analysis of the Holter tapes was arranged by GlaxoSmithKline.The number of participants with normal (NL), abnormal not clinically significant (Abn NCS), and abnormal clinically significant (Abn CS) ECG findings, as well as those with unavailable results (NA) at Screening and Day 7, are reported. Clinical significance was based on the medical and scientific judgement of the investigator or qualified designee.
Maximum and Mean (0-24 Hour) Heart Rate From Holter Monitoring on Day 7
Time Frame: Day 7
Maximum heart rate (Max HR) and mean HR from 0-24 hour Holter monitoring on treatment Day 7 were derived. The analysis was adjusted for treatment and Baseline, where Baseline is defined as the corresponding summary measure (i.e., mean heart rate \[0-24 hours\] or maximum heart rate \[0-24 hours\]) from screening records.
Mean Forced Expiratory Volume in One Second (FEV1) at Screening and on Days 1 and 7
Time Frame: Screening, Day 1, and Day 7
FEV1 is a measure of lung function and is defined as the maximal amount of air that can be forcefully exhaled in one second. FEV1 was measured at Screening, pre-dose, and 4 hours (hr) post-dose on Day 1 and Day 7. FEV1 tests were repeated until three technically acceptable measurements were made.
Total Number of Salbutamol Doses Taken Over the 7 -Day Study Period
Time Frame: Day 1 to Day 7
The total number of salbutamol doses taken per day was recorded by the participants in their dairy card over the entire 7-day treatment period. Diaries were reviewed by the Investigator when participants were admitted to the unit on Day 1, Day 7, and Day 8. Salbutamol was given as rescue medication, defined as a quick-relief or fast-acting medication that is given in addition to the investigational drug or placebo that can alleviate symptoms due to disease or lack of efficacy of the study treatment.
