Bioequivalence Study to Compare Fluticasone Furoate (FF) 1-strip Inhaler With FF 2-strip Inhaler and With FF/Vilanterol Combination

• Status: Completed
• Trial end date: 2012-03-12
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to determine the bioequivalence of fluticasone furoate (FF) inhalation powder (single strip configuration) compared with FF inhalation powder (two strip configuration) and compared with FF / vilanterol (VI) inhalation powder. Fluticasone furoate (FF), is being developed both as a monotherapy for the treatment of asthma and in combination with vilanterol (VI) for the treatment of asthma and Chronic Obstructive Pulmonary Disease (COPD). Thirty healthy male and female subjects will be enrolled in the study to ensure twenty-four evaluable subjects.

• Lead Sponsor: GlaxoSmithKline
• Treatments: Fluticasone; Xhance

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.

• Male or female between 18 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 Child-bearing potential and agrees to use one of the contraception methods listed in Section 8.1 of the protocol for an appropriate period of time prior to the start of dosing to sufficiently minimize the risk of pregnancy at that point. Female subjects must agree to use contraception until completion of the follow-up visit.

• Body Mass Index (BMI) within the range 18.5-29.0 kg/m2 (inclusive).

• Aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase and bilirubin are less than or equal to 1.5x Upper Limit of Normal (ULN) (isolated bilirubin greater than 1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin is less than 35%).

• Average QTcF less than 450 msec.

• Forced Expiratory Volume in 1 second (FEV1) greater than or equal to 85% predicted at screening.

• Subjects who are current non-smokers, who have not used any tobacco products in the 12 month period preceding the screening visit, and have a pack history of less than or equal to 5 pack years (number of pack years = (number of cigarettes per day/20) x number of years smoked)

• Able to satisfactorily use the novel dry powder inhaler (NDPI)

• Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form. Subjects must have signed the Informed Consent Form (ICF) prior to the commencement of any screening activities.

Exclusion Criteria:

• As a result of medical interview, physical examination or screening investigations, the principal investigator or delegate physician deems the subject unsuitable for the study. Subjects must not have a systolic blood pressure above 140 mmHg or a diastolic pressure above 90 mmHg.

• The subject has a history of breathing problems in adult life (e.g. history of asthmatic symptomatology). Screening lung function tests (FEV1) will be performed to confirm normal lung function parameters (greater than or equal to 85% predicted).

• Subjects who have suffered a lower respiratory tract infection within 4 weeks of the screening visit.

• Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).

• The subject has been treated for or diagnosed with depression within six months of screening or has a history of significant psychiatric illness.

• A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening

• A positive test for Human Immunodeficiency Virus (HIV) antibody.

• History of regular alcohol consumption within 6 months of the study defined as an average weekly intake of greater than 21 units for males or greater than 14 units for females.

• A positive pre-study drug/alcohol screen or when randomly tested during the study.

• Positive cotinine and urine alcohol test at screening or on admission to the Unit.

• The subject has participated in a clinical trial and has received an investigational product within the following time period prior to the first dosing day in the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).

• Exposure to more than four new chemical entities within 12 months prior to the first dosing day.

• The subject has taken systemic, oral or depot corticosteroids less than 12 weeks before the screening visit.

• The subject has taken inhaled, intranasal or topical steroids less than 4 weeks before the screening visit.

• Use of 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 longer) prior to the first dose of study medication, unless in the opinion of the Investigator and GSK Medical Monitor the medication will not interfere with the study procedures or compromise subject safety.

• History of sensitivity to any of the study medications, including immediate or delayed hypersensitivity to any beta-agonist, sympathomimetic drug, or any intranasal, inhaled or systemic corticosteroid therapy; known or suspected sensitivity to the constituents of the new powder inhaler (i.e. lactose or magnesium stearate), or a history of drug or other allergy that, in the opinion of the investigator or GSK Medical Monitor, contraindicates participation.

• History of severe milk protein allergy.

• Consumption of red wine, seville oranges, grapefruit or grapefruit juice pummelos, exotic citrus fruits, grapefruit hybrids or fruit juices from 7 days prior to the first dose of study medication.

• Where participation in the study would result in donation of blood or blood products in excess of 500 mL within a 30 day period.

• Pregnant females as determined by positive serum hCG test at screening or by positive serum/urine hCG test prior to dosing.

• Lactating females.

• Unwillingness or inability to follow the procedures outlined in the protocol.

• Subject is mentally or legally incapacitated.

• Vulnerable subjects (eg kept in detention) or Parexel / GSK employees
