A Dose-Finding Study of GSK2894512 Cream in Subjects With Atopic Dermatitis (AD)

NRS is a 11-point tool ranging from 0 (absent) to 10 (worst imaginable) to assess the severity of 11 disease-related signs and symptoms including itching, discoloration, bleeding, oozing, cracking, scaling, flaking, dry/rough, painful, burning, and stinging. Participants were asked to complete the self-administered sign and symptom severity diary containing NRS using a recall period of the past 24 hours. Question 1 of the diary was used to assess itch. Mean change from Baseline to Week 12 in weekly average of daily itch/pruritus based on the NRS was presented using mean and standard deviation (SD). Baseline was defined as the latest assessment prior to first dose and Change from Baseline was defined as post-dose weekly average value minus Baseline value.

The EASI scoring system is a standard clinical tool for assessing the severity of AD that takes into account the overall severity of erythema, infiltration/papulation, excoriation, and lichenification, as well as the extent of BSA affected with AD. These 4 clinical signs were graded on a 4-point scale (0 [absent] to 3 [severe]) for each of the 4 specified body regions (head and neck, upper extremities, lower extremities, and trunk). Body area involvement ranged from 0 (0%) to 6 (90-100%). Total EASI score was calculated as a sum of scores of all 4 specified body region. Range for EASI total score is 0 (absent) to 72 (severe). Baseline was defined as the latest assessment prior to first dose and change from Baseline was defined as post dose visit value minus Baseline value. Mean change from Baseline was presented in the form of mean and SD. Only those participants with data available at the specified data points were analyzed (represented by n= X in the category titles).
