  Purpose

GW642444 is a potent and selective long-acting beta2 agonist; GSK573719 is a long-acting, inhaled, muscarinic receptor antagonist (or anticholinergic) bronchodilator. Both are in development as once daily (QD) monotherapies for the treatment of Chronic Obstructive Pulmonary Disease (COPD). Development of these two inhaled drugs as a combination therapy is also planned and would have potential for improved efficacy and patient benefit as they both work through different receptor pathways and the combined bronchodilatory effect might be additive.

This study is a randomised, double blind, placebo-controlled, four-way crossover study which will assess the safety, tolerability, pharmacodynamics (PD) and pharmacokinetics (PK) of GSK573719 and GW642444 in sixteen healthy Japanese subjects. Subjects will receive four possible treatments as single inhaled doses, receiving the two monotherapies separately, the monotherapies concurrently, and placebo.

Blood samples for PK analysis will be taken at regular intervals after dosing. Safety will be assessed by measurement of heart rate, blood pressure, ECG and twenty-four hour Holter monitoring, potassium, safety laboratory data and review of adverse events.

Arms Assigned Interventions
Experimental: GSK573719, GW642444, GSK573719+GW642444, placebo
This is a four-way cross-over study. Subjects, healthy volunteers, will receive a single dose of GSK573719 (500ug), GW642444 (50ug), GSK573719 (500ug)+GW642444 (50ug) administered concurrently, or placebo at each of the four treatment periods. There is a minimum wash-out period of seven days between doses. On enrolment into the study, subjects will be assigned to one of four treatment sequences which are based on a Williams design in accordance with the randomization schedule generated by GSK prior to study start.
Drug: GSK573719
GSK573719 is a long-acting, inhaled, muscarinic receptor antagonist or anticholinergic bronchodilator. GW642444 is a potent and selective long-acting beta-2 agonist. Both are in development for once daily monotherapies for the treatment of COPD. In this study, their effects are investigated following individual and concurrent administration.

  Eligibility

Ages Eligible for Study:   20 Years to 65 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring. A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the Investigator and the GSK Medical Monitor agree that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
  • Japanese ethnic origin defined as having been born in Japan with four ethnic Japanese grandparents and able to speak Japanese.
  • Male or female between 20 and 65 years of age inclusive, at the time of signing the informed consent.
  • A female subject is eligible to participate if she is of non-childbearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) > 40 MlU/ml and estradiol < 40 pg/ml (<140 pmol/L) is confirmatory].
  • Male subjects must agree to use one of the contraception methods listed in Section 8.1. This criterion must be followed from the time of the first dose of study medication until completion of the follow-up visit.
  • Body weight > or equal to 45 kg and BMI within the range 18-28 kg/m2 inclusive.
  • AST, ALT, alkaline phosphatase and bilirubin < or equal to 1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
  • Average QTcB or QTcF < 450 msec; or QTc < 480 msec in subjects with Bundle Branch Block taken from triplicate assessments at screening.
  • No clinically active and relevant abnormality on 12-lead ECG or 24h Holter ECG at screening.
  • Normal spirometry (FEV1 ≥ 80% of predicted, FEV1/FVC ≥ 70%).
  • Non-smokers (never smoked or not smoking for >6 months with <10 pack years history (Pack years = (cigarettes per day smoked/20) x number of years smoked))
  • A signed and dated written informed consent is obtained from the subject
  • The subject is capable of giving informed consent, which includes compliance with the requirements and restrictions listed in the consent form
  • Available to complete the study

Exclusion Criteria:

  • Any clinically important abnormality identified at the screening medical assessment (physical examination/medical history), clinical laboratory tests, or ECG (12-lead). A 24hr Holter monitoring recording outside normal limits.
  • A history of breathing problems (i.e. history of asthmatic symptomatology, unless asthma in childhood that has now resolved and no longer requires maintenance therapy which should not be an exclusion).
  • A mean QTc(B) value at screening >450msec, or an ECG that is not suitable for QT measurements (e.g. LBBB or poorly defined termination of the T wave).
  • A history of elevated resting blood pressure or a mean blood pressure higher than 140/90 mmHg at screening.
  • A mean heart rate outside the range 40-90 bpm at screening.
  • The subject has a positive pre-study drug/alcohol screen. A minimum list of drugs that will be screened for include amphetamines, barbiturates, cocaine, opiates and benzodiazepines. The detection of drugs with a legitimate medical use would not necessarily be an exclusion to study participation. The detection of alcohol would not be an exclusion at screening but would need to be negative pre-dose and during the study.
  • A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening.
  • Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome).
  • A positive test for HIV antibody.

  • History of sensitivity to any of the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the investigator or GSK Medical Monitor, contraindicates their participation.
  • Where participation in the study would result in donation of blood or blood products in excess of 500 mL within a 56 day period.
  • Unwillingness or inability to follow the procedures outlined in the protocol. 17. Urinary cotinine levels indicative of smoking or history of regular use of tobacco- or nicotine-containing products prior to screening.
