Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in Weighted Mean Pulse Rate Over (0-4 Hours) at Day 28. | Baseline (Pre-dose, Day 1) and Day 28 | Baseline was the most recent result taken on or before pre-dose (Day 1). The analysis was performed using a Repeated Measures Model. This model used all available weighted mean pulse rate values recorded. Change from Baseline was calculated as (Change from Baseline = Assessment value - Baseline value). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) | On-treatment; from treatment start until one day after treatment stop (Up to Day 29) | AE was 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. SAE include AEs those result in death, a life-threatening AE, inpatient hospitalization or prolongation of existing hospitalization, a persistent or significant incapacity or substantial disruption of the ability to conduct normal functions, or a congenital anomaly/birth defect. Important medical events that may not result in death, be life-threatening, or require hospitalization may be considered serious when, based upon appropriate medical judgment, they may jeopardize the participant and may require medical or surgical intervention to prevent one of the outcomes listed in this definition. |

Outcome results
Change From Baseline in Weighted Mean Pulse Rate Over (0-4 Hours) at Day 28.
Baseline was the most recent result taken on or before pre-dose (Day 1). The analysis was performed using a Repeated Measures Model. This model used all available weighted mean pulse rate values recorded. Change from Baseline was calculated as (Change from Baseline = Assessment value - Baseline value).
Time frame: Baseline (Pre-dose, Day 1) and Day 28
Population: Intent-to-Treat (ITT) Population comprised of all participants who were randomized to study treatment and took at least one dose of study medication. Only those participants available at the specified time points were analyzed.
| Arm | Measure | Value (LEAST_SQUARES_MEAN) | Dispersion |
|---|---|---|---|
| Placebo | Change From Baseline in Weighted Mean Pulse Rate Over (0-4 Hours) at Day 28. | -3.8 Beat per minute (bpm) | Standard Error 1.78 |
| GSK233705/GW642444 | Change From Baseline in Weighted Mean Pulse Rate Over (0-4 Hours) at Day 28. | -4.8 Beat per minute (bpm) | Standard Error 1.32 |
Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)
AE was 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. SAE include AEs those result in death, a life-threatening AE, inpatient hospitalization or prolongation of existing hospitalization, a persistent or significant incapacity or substantial disruption of the ability to conduct normal functions, or a congenital anomaly/birth defect. Important medical events that may not result in death, be life-threatening, or require hospitalization may be considered serious when, based upon appropriate medical judgment, they may jeopardize the participant and may require medical or surgical intervention to prevent one of the outcomes listed in this definition.
Time frame: On-treatment; from treatment start until one day after treatment stop (Up to Day 29)
Population: ITT Population.
