A Study to Test the Effect of 2 Different Doses of Topical GW870086X on Atopic Dermatitis Also Including a Postive Control and a Placebo

Three target lesions were selected and each of the 3 target lesions were assessed separately using the TIS for erythema, oedema/papulation, and excoriation using a score of 0 - 3 as 0 = absent, 1 = mild, 2 = moderate, 3 = severe. Each participant had at least 3 index lesions (=> 1square centimeter in size) with a sum score of =>4 and =< 6 for erythema, oedema/populations and excoriations using the TIS rating scale at screening. The index lesions represented common lesions i.e. not the most or least severe lesions. The total TIS score for a lesion was calculated as the sum of each of the component scores i.e. may range from 0 (no symptoms) to 9 (severe symptoms). The values of Day 1 assessments were considered as Baseline values. The change from Baseline was calculated by subtracting the Baseline TIS score from Day 22 values TIS score.

Three target lesions were selected and each of the 3 target lesions were assessed separately using the IGA. The IGA was carried out by a trained dermatologist and score ranged from 0 to 5. The detailed IGA scale is as: 0-Clear: No inflammatory signs of atopic dermatitis, 1- Almost clear: Just perceptible erythema and just perceptible apulation/infiltration, 2-Mild: Mild erythema and mild papulation/infiltration, 3-Moderate: Moderate erythema, and moderate papulation/infiltration, 4-Severe: Severe erythema and severe papulation/infiltration, 5-Very Severe: Very severe erythema, and very severe papulation/infiltration with oozing/crusting. The participant was considered as responder if each lesion at timepoint, IGA score reduced by 1 grade and improved from Baseline by 2 grades.

AE was defined as any untoward medical occurrence in a participant temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. SAE include AEs those result in death, a life-threatening AE, inpatient hospitalization or prolongation of existing hospitalization, a persistent or significant incapacity or substantial disruption of the ability to conduct normal functions, or a congenital anomaly/birth defect. Important medical events that may not result in death, be life-threatening, or require hospitalization may be considered serious when, based upon appropriate medical judgment, they may jeopardize the participant and may require medical or surgical intervention to prevent one of the outcomes listed in this definition. Number of participants with AEs and SAEs were reported.

Laboratory ranges of PCI represented as multiplier of lower limit of normal [LLN]; Multipliers of upper limit of normal (ULN). Laboratory ranges of PCI for white blood cell count (0.67×LLN; 1.82×ULN), neutrophil count (0.83×ULN), hemoglobin for male (1.03×ULN) and for female (1.13×ULN), hematocrit for male (1.02×ULN) for female (1.17×ULN), platelet count (0.67×LLN; 1.57), lymphocytes (0.81×LLN), albumin (0.86 ×LLN), calcium (0.91×LLN; 1.06×ULN), glucose (0.71×LLN; 1.41×ULN), potassium (0.86×LLN; 1.10×ULN), sodium (0.96×LLN; 1.03×ULN), aspartate amino transferase (>= 2x ULN), alanine transaminase (>=2x ULN), alkaline Phosphatase (>=2x ULN), total bilirubin (>=1.5x ULN). Only those parameters for which at least one value of PCI was reported are summarized. The number of participants with PCI hematology and clinical chemistry findings at any visit during the treatment and follow-up were reported.

12-lead ECG was obtained. The standard ECG criteria of PCI were 1) absolute QTc Interval, > 450 milliseconds (msec), 2) increase from Baseline in QTc > 60 msec 3) absolute PR Interval, <110 and >220 msec, 4) absolute QRS Interval, < 75 and >110 msec. The number of participants with PCI ECG findings at any visit during the treatment and follow-up were reported.

The PCI ranges (low and high) of the vital sign parameters were for systolic blood pressure (<85 and >160 millimeter of mercury [mmHg]), diastolic blood pressure (<45 and >100 mmHg) and heart rate (<40 and >110 beats per minute). Only those parameters for which at least one value of PCI was reported are summarized. There were no values of PCI in vital signs parameters over the course of the study.

Cmax was planned to be determined directly from the raw concentration-time data. The pharmacokinetic parameters were planned to be calculated by standard non-compartmental analysis using Win-Nonlin Pro-Version 5.2 or higher.

Tmax was planned to be determined directly from the raw concentration-time data. The pharmacokinetic parameters were planned to be calculated by standard non-compartmental analysis using Win-Nonlin Pro-Version 5.2 or higher.

The area under the plasma concentration-time curve to the last quantifiable concentration (AUC[0-t]) and area under the plasma concentration-time curve over the dosing interval (AUC[0-tou]) was planned to be determined using the linear trapezoidal rule for increasing concentrations and the logarithmic trapezoidal rule for decreasing concentrations. The pharmacokinetic parameters were planned to be calculated by standard non-compartmental analysis using Win-Nonlin Pro-Version 5.2 or higher.

A 4 millimeter (mm) punch skin biopsy was taken pre- and post-treatment (Day 1 and Day 21) from each of the 3 index lesions. The results were not analyzed for this outcome measure.
