An AE is defined as 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. A serious adverse event (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. Medical or scientific judgment should be exercised in deciding whether reporting is appropriate in other situations. Refer to the General AE/SAE module for a complete list of AEs and SAEs.

Peak Expiratory Flow (PEF) is defined as the maximum airflow during a forced expiration beginning with the lungs fully inflated. PEF is calculated as the maximum of three readings taken at each timepoint for each participant. Baseline is defined as the pre-dose measurement at Day 1 for the respective period. Subject 2308 received VI 25 µg in both treatment periods, and contributed twice to the summary of VI 25 µg (n=28).
SBP and DBP were measured at Day 1, Day 8, and Day 14 of the respective treatment period. PD=post-dose. Baseline is defined as the pre-dose measurement at Day 1 for the respective period. Subject 2308 received VI 25 µg in both treatment periods, and contributed twice to the summary of VI 25 µg (n=28).

Heart rate (HR) was measured at Day 1 and Day 14 of the respective treatment period. hr=hour. Weighted means were derived using the linear trapezoidal rule. Actual relative times were used for the calculation except where actual times were missing. If any actual times were missing, planned relative times were used for these observations. For 0-8 hr parameters, treatment, period, participant Baseline, and period Baseline were fitted as fixed effects, and participant was fitted as a random effect. For 0-2 hr parameters, treatment, period, day (1 and 14), participant Baseline, period Baseline, and treatment\*day interaction were fitted as fixed effects, and participant was fitted as a random effect. Subject 2308 received VI 25 µg in both treatment periods, and contributed twice to the summary of VI 25 µg (n=28).
The electrocardiographic (ECG) parameter QT duration corrected using Fridericia's formula (QTcF) was measured at Day 1 and Day 14 of the respective treatment period. hr=hour. For 0-8 hr parameters, treatment, period, participant Baseline, and period Baseline were fitted as fixed effects, and participant was fitted as a random effect. For 0-2 hr parameters, treatment, period, day (1 and 14), participant Baseline, period Baseline, and treatment\*day interaction were fitted as fixed effects, and participant was fitted as a random effect. Subject 2308 received VI 25 µg in both treatment periods, and contributed twice to the summary of VI 25 µg (n=28).

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 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, may jeopardize the participant or may require medical or surgical intervention to prevent one of the other outcomes listed in this definition.
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.

GW642444 is an investigational small molecule being studied for the treatment of respiratory conditions, specifically chronic obstructive pulmonary disease (COPD) and asthma. It has been evaluated in clinical trials involving adult and pediatric patients with these conditions.
GW642444 is being developed by GSK plc, a global pharmaceutical company listed on the stock exchange under the ticker symbol GSK. The company has sponsored multiple clinical trials to investigate the drug's safety and efficacy in respiratory diseases.
GW642444 is in Phase 2 clinical development. It has completed six trials, including Phase 1 and Phase 2 studies, with no active trials currently ongoing. The drug remains investigational and has not been approved by regulatory authorities.
GW642444 has completed six clinical trials, including NCT00354874 in asthmatic patients, NCT00702910 in COPD patients, NCT01286831 in healthy volunteers, and NCT01453296 in pediatric asthma subjects. All trials are completed with a total enrollment of 194 participants.
GW642444 and GW642444M are related but distinct forms of the same drug. GW642444M is a specific formulation of GW642444 that was investigated in a clinical trial (NCT00702910) to compare the effects of inhaling different formulations in asthmatic patients.
