Study to Evaluate the Safety, Tolerability and Pharmacokinetic of Single and 14 Day Repeat Topical Application of GSK1940029

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 GlaxoSmithKline (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 (in questionable cases a blood sample with simultaneous follicle stimulating hormone [FSH] >40 milli international units MIU/ milliliter (mL) and estradiol < 40 picograms (pg)/mL (<147 picomole [pmol]/liter [L]) is confirmatory). Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will not be allowed.
• Male subjects with female partners of child-bearing potential must agree to use one of the contraception methods listed in the Protocol. This criterion must be followed from the time of the first dose of study medication until after study follow-up visit.
• Alanine amino transfrase, alkaline phosphatase and bilirubin <=1.5 x ULN (upper limit of normal) (isolated bilirubin >1.5 x ULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
• Based on single or averaged assessments, corrected QT interval (QTc) < 450 milliseconds (msec); or QTc <480 msec in subjects with Bundle Branch Block.

Exclusion criteria

• A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening
• Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome). Subjects with a history of gall stones, asymptomatic gallstones or cholecystectomy will be excluded.
• A positive pre-study drug/alcohol screen.
• 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 >14 standard drinks. One standard drink is equivalent to 10 gram of alcohol: 285 mL of beer, 100 mL of wine or 30 mL of 40% alcohol by volume distilled spirits.
• History of or current meibomian gland dysfunction or dry eye disease
• History or presence of significant skin disorder (such as but not limited to severe (extensive) atopic dermatitis, severe eczema, psoriasis or skin cancer) that would in any way confound interpretation of the study results, or subjects who present with damaged skin including sunburn, moles, uneven skin tones, scar tissue, tattoos, body piercings, sunburn, branding or other disfiguration on or near the intended site of application which could interfere with the grading.
• History of cutaneous photodisorder, such as photoallergic reaction or polymorphic light eruption. - History of cold urticaria and reactions to extreme temperatures.
• History of allergy to soaps, lotions, cosmetics, tape/adhesives, petrolatum or latex or topical drugs of same class as the study medication.
• History of sensitivity to any of the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the investigator or GSK Medical Monitor, contraindicates their participation.
• History of sensitivity to heparin or heparin-induced thrombocytopenia.
• History of severe, chronic asthma or significant allergies (including food, drug or cutaneous allergies). Subjects with the presence or a history of atopy (seasonal allergies, allergic rhinitis) or mild (limited) eczema will be allowed to participate in the study, although applications at sites with active eczema will not be allowed.
• Use of topical medications such as but not limited to retinoids, steroids, and transdermal hormone replacement therapies on or near the intended site of application within 8 weeks prior to dosing through treatment follow up. Use of other topical preparations such as those containing vitamins, supplements or herbal within 2 weeks prior to dosing through treatment follow up.
• Unable to refrain from the use of topical medications from the initial dose of study medication through follow-up.
• Foreseeable intensive ultraviolet (UV) exposure during the study (solar or artificial) as follows: subjects must not be exposed to direct sunlight for sun tanning or exposed to skin tanning devices (e.g. sunbed) for the duration of the study.
• Participation in any patch test for cumulative irritation or sensitization within 4 weeks preceding the first dose of study medication.
• Exposure to more than four new chemical entities within 12 months prior to the first dosing day.
• 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).
• 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 (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 mL within a 56 day period.
• Unwillingness or inability to follow the procedures outlined in the protocol.
• Subject is mentally or legally incapacitated.
• Unable to refrain from consumption of red wine, seville oranges, grapefruit or grapefruit juice and/or pummelos, exotic citrus fruits, grapefruit hybrids or fruit juices from 7 days prior to the first dose of study medication
