Clinical Trial Summary

In order to obtain information on a wider range of doses of GW642444 (a possible new medication to treat asthma) than has been previously examined in asthmatic patients, this current study will be conducted at doses of 25 100 and 400 mcg of GW642444 and will be compared with salmeterol (50 mcg twice daily). This study will be conducted in a similar manner to a study that has already been completed (study number B2C101762) which examined repeat doses of 50, 100 and 200 mcg of GW642444. The data obtained will compliment the data from study B2C101762 and will provide confidence (or not) that the desired bronchodilation can be achieved and maintained without undesirable side effects.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Mean change from Baseline (pre-dose on Day 1) in the mean of 23 and 24 hour (h) visit (pre-bronchodilator and pre-dose) trough FEV1 after repeat dosing over 14 days	The forced expiratory volume in one second (FEV1) is the amount of air exhaled in one second after an forceful inspiration. Change from Baseline is the value at indicated time point minus the Baseline value. Baseline was defined as the value recorded pre-dose (before dosing) on Day 1. Least square mean change along with standard error has been presented.	From Baseline (pre-dose on Day 1) and up to 14 days
Secondary	Mean change from Baseline (pre-dose on Day 1) in weighted mean clinic FEV1 on Day 1 and Day 14	The forced expiratory volume in one second is the amount of air exhaled in one second after an forceful inspiration. Change from Baseline is the value at indicated time point minus the Baseline value. Baseline was the pre-dose value recorded on Day 1. Weighted means have been presented as least square means. Analysis performed using mixed effect ANCOVA with fixed effects covariates of baseline FEV1, center, sex, age, treatment period, treatment and the mean of the participants Baseline values. Participant was fitted as a random coefficient.	From Baseline (pre-dose on Day 1) and at 0-2 h, 0-4, and 0-24 h Days 1 and 14
Secondary	Mean change from Baseline (pre-dose on Day 1) in morning (AM) Peak expiratory flow rate (PEFR) from electronic flow meter over Days 2-15	The forced expiratory volume in one second is the amount of air exhaled in one second after an forceful inspiration. Change from Baseline is the value at indicated time point minus the Baseline value. AM PEFR values were measured by electronic flow meter. PEFR is maximum speed of expiration of participant as measured by the device and AM PEFR was calculated in each morning, over period. Analysis performed using mixed effect ANCOVA with fixed effects covariates of Baseline AM PEFR, center, sex, age, treatment period, treatment and the mean of the participants Baseline values. Participant was fitted as a random coefficient. Least square mean change along with standard error has been presented.	Baseline (pre-dose on Day 1) and up to 15 days
Secondary	Mean change from Baseline (pre-dose on Day 1) in the evening (PM) PEFR from electronic flow meter over Days 1-14	The forced expiratory volume in one second is the amount of air exhaled in one second after an forceful inspiration. Change from Baseline is the value at indicated time point minus the Baseline value. PM PEFR values were measured by electronic flow meter. PEFR is maximum speed of expiration of participant as measured by the device and PM PEFR was calculated in each evening over period. Analysis performed using mixed effect ANCOVA with fixed effects covariates of Baseline PM PEFR, center, sex, age, treatment period, treatment and the mean of the participants Baseline values. Participant was fitted as a random coefficient. Least square mean change along with standard error has been presented.	Baseline (pre-dose on Day 1) and up to 14 days
Secondary	Mean change from Baseline (pre-dose on Day 1) in AM FEV1 from electronic flow meter over Days 2-15	The forced expiratory volume in one second is the amount of air exhaled in one second after an forceful inspiration. Change from Baseline is the value at indicated time point minus the Baseline value. AM FEV1 values were measured by electronic flow meter and was measured in the morning over period. Analysis performed using mixed effect ANCOVA with fixed effects covariates of baseline AM FEV1, center, sex, age, treatment period, treatment and the mean of the participants Baseline values. Participant was fitted as a random coefficient. Least square mean change along with standard error has been presented.	Baseline (pre-dose on Day 1), Day 2, and Day 15
Secondary	Mean change from Baseline (pre-dose on Day 1) in PM FEV1 from electronic flow meter over 14 days	The forced expiratory volume in one second is the amount of air exhaled in one second after an forceful inspiration. Change from Baseline is the value at indicated time point minus the Baseline value. PM FEV1 values were measured by electronic flow meter and was measured in the evening over period. Analysis performed using mixed effect ANCOVA with fixed effects covariates of Baseline PM FEV1, center, sex, age, treatment period, treatment and the mean of the participants Baseline values. Participant was fitted as a random coefficient. Least square mean change along with standard error has been presented.	Baseline (pre-dose on Day 1) and up to Day 14
Secondary	Change in AM PEFR from Pre-AM Dose to Post-AM Dose at Day1, 7, and 14	The forced expiratory volume in one second is the amount of air exhaled in one second after an forceful inspiration. Change in post-AM PEFR is the value at indicated time point minus the pre-AM PEFR value. AM PEFR values were measured by electronic flow meter. PEFR is maximum speed of expiration of participant as measured by the device and AM PEFR was calculated in each morning, over period.	Day 1, 7, and 14
Secondary	Change in PM PEFR from Pre-PM Dose to Post-PM Dose at Day1, 7, and 14	The forced expiratory volume in one second is the amount of air exhaled in one second after an forceful inspiration. Change in post-PM PEFR is the value at indicated time point minus the pre-PM PEFR value. PM PEFR values were measured by electronic flow meter. PEFR is maximum speed of expiration of participant as measured by the device and PM PEFR was calculated in each morning, over period.	Day 1, 7, and 14
