A Phase II Randomised, Double Blind, Placebo-controlled Study to Evaluate the Efficacy, Safety and Tolerability of CT327 Topical Ointment (0.05% and 0.5% w/w) Compared to Vehicle, in Subjects With Mild or Moderate Atopic Dermatitis and at Least Moderate Pruritus

Study start date: July 1, 2013

Inclusion Criteria: Male and female subjects aged ≥ 12 years. Clinical diagnosis of atopic dermatitis (as defined by Hanifin and Rajka criteria (Appendix F) at screening with: IGA score of 2 or 3 (mild or moderate) Score of ≥ 40mm on all screening pruritus VAS assessments (average and worst over the last 24 hours and current itch) A minimum of 5% and not more than 20% of the subjects' BSA affected by atopic dermatitis (affected is defined as active atopic dermatitis lesions or pruritus) Amenable to treatment with topical treatment Stable disease for ≥1 months prior to screening Exclusion Criteria: Atopic dermatitis only affecting the head or scalp. Unstable or actively infected atopic dermatitis. Concomitant dermatologic or medical condition(s) which may interfere with the investigator's ability to evaluate the subject's response to the study drug. Subjects who have received monoclonal antibody therapy for their atopic dermatitis in the 4 months prior to screening. Subjects who have used systemic immunosuppressive drugs, corticosteroids or received PUVA therapy in the 4 weeks prior to starting study treatment, or are scheduled to start these treatments during the study period. Subjects who have used topical immunomodulators (pimecrolimus, tacrolimus) within 2 weeks of starting study treatment or are scheduled to start these treatments during the study period. Subjects who have used topical corticosteroids from WHO group II, III or IV, or other treatments for atopic dermatitis, including wet wraps, within 2 weeks prior to starting study treatment or are likely to require treatment with these medications during the study period. Subjects who are unable to abstain from using emollients from baseline (Visit 2) until the end of study treatment (Visit 6). Subjects who are using any concomitant medication(s) that, in the investigators' opinion, could affect the subject's atopic dermatitis or pruritus (for example TADs, SSRI, pregabalin). Subjects using such medications may be included, at the investigators discretion, if they have been stable on treatment for at least 1 month prior to the start of study treatment and no changes to these medications are planned during the study period. Subjects undergoing, or due to have, UVA, or UVB therapy in the 2 weeks prior to starting study treatment or during the study period. Planned exposure of affected areas to excessive sunlight. Subjects with a clinically significant abnormal laboratory safety test and/or 12-lead ECG results at screening.
