Brief Summary:
GSK2894512 (trans-isomer) is a fully synthetic, non-steroidal anti-inflammatory agent. This study is being conducted to evaluate the PK, safety and tolerability of GSK2894512 cream, 1 percent administered topically to healthy adult subjects. PK parameters obtained in this study will be used to support the design of future maximum use PK (MUPK) studies in subjects with atopic dermatitis (AD) and plaque psoriasis or psoriasis (PSO). This is a phase 1, randomized, double-blind, vehicle-controlled, 3-period, sequential, inpatient study consists of a Screening visit, 3 treatment periods and a follow-up visit. GSK2894512 cream, 1 percent (or matching vehicle) will be administered sequentially in the treatment periods. Period 1 will include once daily repeated topical applications on approximately 5000 centimeter (cm) ^2 intact non-occluded skin area for 21 days. Period 2 will include once daily repeated topical applications on approximately 5000 cm^2 intact occluded skin area for 21 days. Period 3 will include a single topical application on up to 400 cm^2 gently taped-stripped skin area. Each treatment regimen will be followed by washout period for approximately 21 days, except for Treatment Period 3. Approximately 26 healthy adult subjects will be enrolled in to the study. Total duration of participation in this study will be approximately 18 weeks.

Secondary Outcome Measures :
  1. Number of subjects with any adverse events (AEs) and serious AEs (SAEs) [ Time Frame: Up to 14 weeks ]
    An AE is any untoward medical occurrence in a clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An SAE is defined as any untoward medical occurrence that: results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, other important medical events judged by physician that may not be immediately life-threatening or result in death or hospitalization but may jeopardize the subject or may require medical or surgical intervention to prevent one of the other outcomes listed in this definition.

  2. Number of subjects with abnormal vital sign findings [ Time Frame: Up to 13 weeks ]
    Vital sign parameters including systolic and diastolic blood pressure, heart rate (HR) and body temperature will be evaluated. Vital sign measurements will be preceded by at least 5 minutes of rest (supine or seated) for the subject in a quiet setting.

  3. Number of subjects with abnormal electrocardiogram (ECG) findings [ Time Frame: Up to 13 weeks ]
    Triplicate 12-lead ECG will be obtained using an ECG machine that automatically calculates the HR and measures PR, QRS, QT, and QT interval corrected for heart rate according to Fridericia's formula (QTcF) intervals on Days -1, 3, 9, 16 and 23 in Period-1 and 2; and on Days -1 and 3 in Period-3.

  4. Number of subjects with abnormal findings in digital holter monitoring [ Time Frame: Up to 13 weeks ]
    Continuous digital 12-lead ECGs will be recorded using 12-lead Holter/12-lead ECG recorder from 1 hour prior to dosing to 24 hours after dosing on Days 1, 2, 7, 8, 14, 15, 21 and 22 in period-1 and 2; and on Days 1 and 2 in Period-3.

  5. Number of subjects with abnormal findings in physical examination [ Time Frame: Up to 13 weeks ]
    Complete physical examination will include review of head and neck, heart, lungs, abdomen, skin, general appearance, height and weight.

  6. Number of subjects with abnormal clinical laboratory findings [ Time Frame: Up to 13 weeks ]
    Serum chemistry, hematological and urine analysis parameters will be evaluated.

  7. Assessment of degree of local irritation as a measure of local tolerability [ Time Frame: Up to 14 weeks ]
    Dermal reactions like erythema, edema, papules at test sites will be visually assessed. Degree of local irritation will be assessed to determine tolerability of topical application of GSK2894512 cream. if a subject is found to meet a dermal response graded 4 (definite edema) and above indicated in Erythema and Dermal Response Grading Scale, the study medication applications will be discontinued. Grade <4 will be recorded as an AE.

  • A female subject is eligible to participate if she is not pregnant (as confirmed by a negative serum human chorionic gonadotrophin (hCG) test at screening phase between days -29 and -14 and negative serum or urine hCG test on Day -1 prior to each treatment period), not lactating, and at least one of the following conditions applies:

    • not a woman of childbearing potential (WOCBP), or
    • is a WOCBP who agrees to follow the specified contraceptive guidance throughout the study, beginning at least 30 days prior to the first cream application and for at least 30 days after the last cream application of the study.
  • Male subject with female partner of childbearing potential must use a male condom and the female partner should use one of the highly effective methods of contraception from the time of first dose of study medication until 30 days after the last cream application of the study.
  • Willing to participate and capable of giving signed informed consent.

  • Subject has a history of hyperhidrosis.
  • Subject had a major surgery within 8 weeks prior to Baseline (Day -1) or has a major surgery planned during the study.
