Brief Summary:
This will be an open-label, non-randomized, single-center study to assess the residency of GSK2894512 in the skin of healthy adult male volunteers with normal barrier function. The study will have two parts, Cohort 1 (Part A) followed by Cohort 2 (Part B). The study will assess the residence time in human skin . The primary objective is to evaluate the residency time in skin following topical application of two formulations of GSK2894512 Cream. The total study duration will be of 15 days including 1 to 7 days of treatment period, 8 to 14 days of post treatment period and 1 day of follow up. The screening period will be up to 28 days prior to Baseline (Day 1).

Condition or disease Intervention/treatment Phase

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 15 participants
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Official Title: Skin Residency Study of Topically Applied GSK2894512 Cream in Healthy Volunteers
Actual Study Start Date : July 7, 2015
Actual Primary Completion Date : September 24, 2015
Actual Study Completion Date : September 24, 2015

Arm Intervention/treatment
Experimental: Open Label Arm
In Cohort 1, study medication (Cream A, 1%) will be applied as a thin layer onto a predefined area of the volar region of the forearm that is large enough to image and collect 3 biopsies (4 mm per biopsy). Vehicle will be applied on Day 1 only, onto a symmetrical location on the opposite forearm from Cream A. In cohort 2, subjects will be enrolled to evaluate Cream A (1%) and a different GSK2894512 Cream, Cream B (1%). Cream A, 1% and Cream B, 1% will be applied as a thin layer to the opposite forearms of the subject. Vehicle will be applied only on Day 1 to a separate area (at least 1.3 cm from study drug) of the forearm from where drug is applied. Both Cream A and Cream B will continue to be applied OD to the same area of the same forearm for 7 days.
Drug: Combination therapy GSK2894512 Cream A + GSK2894512 Cream B
GSK2894512 Cream A, 1% (10mg/g) will be topically applied daily for 7 days as a thin layer onto an area of the volar region of one forearm (up to 1.5% body surface area) and GSK2894512 Cream B, 1% (10mg/g), will be topically applied daily for 7 days to the opposite forearm from Cream A, onto an area of the volar region of one forearm (up to 1.5% body surface area). Both the creams will be weighed to deliver approximately 3mg drug per 1cm^2 of skin.

Drug: Combination therapy Vehicle Cream A + Vehicle Cream B
Vehicle creams A and B will be supplied in individual tubes. Both the creams will be topically applied on Day 1 only to a separate area (at least 1.3 cm from study drug) of the forearm from where drug is applied.




Primary Outcome Measures :
  1. Residence time in skin following topical application of two formulations of GSK2894512 Cream [ Time Frame: Up to Day 15 ]
    Fluorescent lifetime imaging microscopy (FLIM) images will be evaluated to determine if GSK2894512 is detectable in skin. Drug concentrations can be quantified considering the: depth of penetration at each time point and the amount of fluorescence detected. Liquid Chromatography-Mass Spectrometry/Mass Spectrometry (LC-MS/MS) will also be used to measure the concentration of GSK2894512 from biopsies.


Secondary Outcome Measures :
  1. Adverse events (AEs) monitoring after two formulations of GSK2894512 cream [ Time Frame: Up to Day 15 ]
    An AE is any untoward medical occurrence in a patient or clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Serious Adverse Event (SAE) is defined as any untoward medical occurrence that, at any dose: results in death; is life-threatening; requires hospitalization or prolongation of existing hospitalization; results in disability/incapacity, or; is a congenital anomaly/birth defect.

  2. Composite of vital signs assessment including temperature, systolic and diastolic blood pressure and pulse rate of two formulations after two GSK2894512 cream [ Time Frame: Up to Day 15 ]
    Vital signs will be measured in semi-supine position after 5 minutes rest and will include temperature, systolic and diastolic blood pressure and pulse rate

  3. Electrocardiogram (ECG) assessment after two formulations of GSK2894512 cream [ Time Frame: Up to Day 15 ]
    Single 12-lead ECGs will be obtained at each time point during the study using an ECG machine that automatically calculates the heart rate and measures PR, QRS, QT, and corrected QT interval for Bazett's formula (QTcB) intervals

  4. Composite of abbreviated physical examination after two formulations of GSK2894512 cream [ Time Frame: Up to Day 15 ]
    Physical examination will include, at a minimum assessments of Cardiovascular, Respiratory, Gastrointestinal and Neurological systems. Height and weight will also be measured and recorded

  5. Laboratory assessments after two formulations of GSK2894512 cream [ Time Frame: Up to Day 15 ]
    Laboratory assessments including haematology, clinical chemistry, and urinalysis

  6. Local tolerability assessments after two formulations of GSK2894512 cream [ Time Frame: Up to Day 15 ]
    Tolerability will be evaluated on the basis of degree of local irritation.

Criteria

Inclusion Criteria:

  • Males, between 18 and 45 years of age inclusive, at the time of signing the informed consent.

  • Skin tone in the potential test site on the forearm such that erythema and other dermal reactions can be easily visualized, i.e. only Fitzpatrick skin types I (always burns; never tans), II (usually burns; tans with difficulty), III (sometimes mild burn; gradually tans), or IV (rarely burns; tans with ease) will be included. Determination of skin types is based on sunburn and tanning history in response to the first 30 to 45 minutes of sun exposure.
  • A subject with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or exclusion criteria, outside the reference range for the population being studied may be included only if the investigator, in consultation with the Medical Monitor, agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures. Subjects with values outside the normal range should always be excluded from enrolment.
