Condition(s) targeted: Asthma

Intervention: Fluticasone furoate 50 mcg (4 inhalations) (Drug); Fluticasone furoate 100 mcg (4 inhalations) (Drug); Fluticasone furoate 200 mcg (4 inhalations) (Drug); Vilanterol 25 mcg (4 inhalations) (Drug)

Phase: Phase 1

Status: Completed

The purpose of this study is to demonstrate dose proportionality of fluticasone furoate (FF) and equivalence of vilanterol (VI)following single dose administration of FF/VI via the novel dry powder inhaler in healthy subjects.

Clinical Details

Official title: An Open-label, Randomised, 3-way Crossover Single Dose Study to Demonstrate Dose Proportionality of Fluticasone Furoate (FF) and Equivalence of Vilanterol (VI) When Administered as FF/VI Inhalation Powder From the Novel Dry Powder Inhaler in Healthy Subjects.

Study design: Allocation: Randomized, Endpoint Classification: Pharmacokinetics Study, Intervention Model: Crossover Assignment, Masking: Open Label, Primary Purpose: Basic Science

Primary outcome:

Fluticasone furoate area under concentration-time curve (AUC)

Fluticasone furoate maximum observed concentration (Cmax)

Vilanterol area under concentration-time curve (AUC)

Vilanterol maximum observed concentration (Cmax)

Secondary outcome:

Fluticasone furoate time of occurence of maximum concentration (tmax)

Vilanterol time of occurence of maximum concentration (tmax)

Detailed description: The study will be an open-label, randomised, 3-way cross-over single dose study in 24 healthy subjects to demonstrate dose proportionality of fluticasone furoate (FF) and equivalence of vilanterol (VI) following single dose administration of FF/VI via the novel dry powder inhaler. In each of 3 treatment periods, subjects will receive 4 inhalations of 50/25 mcg, 100/25 mcg, 200/25 mcg FF/VI. Blood samples will be taken for pharmacokinetic analysis and safety (12-lead ECGs, clinical laboratory test, vital signs, adverse events) will be monitored following each dose.

12 month period preceding the screening visit, and have a pack history of < or = 5 pack years.

- Able to satisfactorily use the dry powder inhaler.

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 145 mmHg or a diastolic pressure above 85 mmHg unless the Investigator confirms that it is satisfactory for their age.

- The subject has a history of breathing problems in adult life (e. g. history of

asthmatic symptomatology). Screening lung function tests (forced expiratory volume in 1 minute (FEV1)) will be performed to confirm normal lung function parameters (>or=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 HIV antibody.

- A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody

result within 3 months of screening.

- History of heavy regular alcohol consumption within 6 months of the study defined as:

an average weekly intake of >21 units for males or >14 units for females.

- History or regular use of tobacco- or nicotine-containing products within 12 months

prior to screening.

- Positive carbon monoxide or alcohol breath test at screening or on admission to the


- A positive pre-study urine drug screen or when randomly tested during the study.

- 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: 3 months, 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.

- 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.
