Characterization of Exposure From Topical Administration of [14C] Umeclidinium to Axilla or Palm of Healthy Male Subjects

The purpose of this study is to characterize the pharmacokinetics (PK), safety and tolerability of topically applied umeclidinium following single dose topical administration. The results from this study will be used to 1) improve our understanding of the risk of systemic accumulation upon chronic administration, 2) support dosing recommendations in a 2a/2b study for axillary administration and, potentially, a separate combined 2a/2b study for palmar administration, and 3) confirm whether the same formulation can be used for axillary and palmar application for the next studies.

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 (including screening ECG and screening Holter 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 considers the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures. Subjects with significant lab values outside the normal range should always be excluded from enrolment.
• The subject is able to understand and comply with protocol requirements, instructions and protocol-stated restrictions and is likely to complete the study as planned. Subject is willing to provide informed consent.
• Axilla or palm size must be able to accommodate one of the 40 centimeter square (cm^2) templates and, as relevant for the cohort, the protective device.
• Axilla or palm must be free of tattoos, scar tissue or other tissue damage that could affect drug absorption or subject safety.
• Males between 30 and 55 years of age inclusive, at the time of signing the informed consent.
• Body Mass Index (BMI) within the range 18-27 kilogram per meter square (kg/m^2) (inclusive).

• Diagnosis of narrow-angle glaucoma, prostatic hypertrophy or bladder neck obstruction that in the opinion of the study investigator or GSK medical monitor would prevent use of an anticholinergic and therefore study participation.
• A mean QTcF value at screening >450msec, the QTcF of all 3 screening ECGs are not within 10% of the mean, or an ECG that is not suitable for QT measurements (e.g. poorly defined termination of the T wave).
• A history of elevated resting blood pressure or a mean blood pressure equal to or higher than 139/89 millimeters of mercury (mmHg) at screening or prior to dosing.

• Unable to refrain from the 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 (if available, 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.
• Where participation in the study would result in donation of blood or blood products in excess of 500 milliliter (mL) within a 60 day period.
• History of sensitivity to heparin or heparin-induced thrombocytopenia.
