Summary

This is a multi-national, randomized, double-blind, 3-period crossover, incomplete block design to evaluate 5 once-daily and 2 twice-daily doses of GSK573719 in combination with placebo. The study will explore the dose range of GSK573719 in asthmatic subjects who are currently using non-ICS controller medications. Subjects will participate in the study for up to a maximum of 14 weeks. At randomization subjects will be stratified by age to ensure adequate exposure to GSK573719 throughout the expected age range. The primary endpoint will be trough FEV1 obtained 24 hours after the last morning dose on Day 14 of each treatment sequence.

A sub-group of subjects at selected sites (approximately 30% of the total population) will have additional serial assessments for spirometry, ECG and Holter, and pharmacokinetic sampling at the start and end of each treatment period. Safety assessments will include monitoring for adverse events, laboratory tests, asthma symptom assessments and twice daily PEF evaluation. Consenting subjects will have a blood sample taken for pharmacogenetic analysis.

Conditions

Interventions

DRUG

GSK573719 Active treatment or Placebo

Eligible subjects will be randomised to a sequence of three treatments from 8 possible arms: 7 active drug doses (15.6mcg, 31.25 mc, 62.5mcg 125mcg or 250mcg GSK573719 once daily; 15.6mcg or 31.25 mcg GSK573719 taken twice daily) or matched placebo.

PROCEDURE

GSK573719 (Sub-group cohort)

Subjects at selected Sub-group sites (approximately 30% of the total population) will have additional serial assessments and procedures (including blood and urine samples for pharmacokinetic analysis) at the start (Day 1) and at the end (Days 14 and 15) of each treatment period. On Day 14 of each treatment period subjects will remain overnight at the clinic for 24-hour assessments, including spirometry, ECGs, and 24-hour Holter monitoring.

DRUG

Salbutamol/Albuterol

Salbutamol/Albuterol, short-activing beta agonist provided to all subjects to be taken as needed for the relief of asthma symptoms.throughout the study period, including washout periods
