Comparing Two Respiratory Drugs in Combination and Separately From a Novel Inhaler Device in Healthy Japanese Subjects

Phase 1
Completed
Conditions
Asthma
Interventions
Registration Number
NCT00625196
Lead Sponsor
GlaxoSmithKline
Brief Summary

A combination of the corticosteroid GW685698X and the long-acting ß2-agonist GW642444M is being developed for once daily administration for the maintenance treatment of asthma and COPD. GW642444M and GW685698X will be simultaneously co-administered from a single device and compared with GW642444M and GW685698X administered separately in order to determine whether co-administration affects the safety, tolerability, pharmacodynamic and/or pharmacokinetics of either compound in healthy Japanese subjects.

Exclusion Criteria
  • As a result of medical interview, physical examination or screening investigations, the principle investigator or delegate physician deems the subject unsuitable for the study. Subjects must not have a systolic blood pressure above 145 mmHg or a diastolic pressure above 85 mmHg unless the Investigator confirms that it is satisfactory for their age.
  • The subject has been treated for or diagnosed with depression within six months of screening or has a history of significant psychiatric illness.
  • Subjects who have suffered an upper or lower respiratory tract infection within 4 weeks of the screening visit.
  • Liver function tests (AST, ALT or ALP) greater than 1.5 of the upper limit of laboratory reference range.
  • 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 physician responsible, contraindicates their participation.
  • History of milk protein allergy.
  • The subject has taken prescription or non-prescription drugs, including vitamins, herbal and dietary supplements (including St John's Wort) within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is the longer) prior to the first dose of study medication, unless in the opinion of the Investigator and Sponsor the medication will not interfere with the study procedures or compromise subject safety.
  • The subject has taken oral corticosteroids less than 8 weeks before the screening visit
  • The subject has taken inhaled, intranasal or topical steroids less than 4 weeks before the screening visit
  • History of alcohol/drug abuse or dependence within 12 months of the study
  • Abuse of alcohol defined as an average weekly intake of greater than 21 units or an average daily intake of greater than 3 units (males) or defined as an average weekly intake of greater than 14 units or an average daily intake of greater than 2 units (females). One unit is equivalent to a 285mL glass of full strength beer or 425mL schooner of light beer or 1 (30mL) measure of spirits or 1 glass (100mL) of wine
  • The subject has participated in a clinical trial and has received a drug or a new chemical entity within 30 days or 5 half-lives, or twice the duration of the biological effect of any drug (whichever is longer) prior to the first dose of current study medication.
  • Exposure to more than four new chemical entities within 12 months prior to the first dosing day.
  • The subject has donated a unit (450mL) of blood within the previous 16 weeks or intends to donate within 16 weeks after completing the study.
  • A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening.
  • The subject has tested positive for HIV antibodies.
  • The subject has a positive pre-study urine drug screen. A minimum list of drugs that will be screened for include amphetamines, barbiturates, cocaine, opiates, cannabinoids and benzodiazepines.
  • Positive CO or alcohol breath test at screening or on admission to the Unit.
  • History of any adverse reaction including immediate or delayed hypersensitivity to any ICS, β2 agonist or sympathomimetic drug.
  • Any known or suspected sensitivity to the constituents of GW642444M or GW685698X inhalation powder (i.e., lactose, magnesium stearate).
  • Subjects at risk of non-compliance.
