Atopic dermatitis is presented as eczematous lesions. Some rashes, discharge, and blisters appear at the acute stage and skin lesions of lichenification appear as the skin becomes thick and leathery at the chronic stage. If not treated properly, a vicious cycle of inflammation of the immune system and further damage to the skin barrier is produced. In particular, enhanced immune reaction to external environmental stimuli plays a major role in inducing pruritis, an essential feature of atopic dermatitis. Pruritis triggers scratching, which in turn leads to an 'itch-scratch-itch' vicious cycle', resulting in secondary skin changes. Therefore, it is important to break the vicious cycle, which worsens the symptoms by means of an optimal treatment.~NCP112 is a first-in-class drug candidate, with a novel target strategy for atopic dermatitis, different from those of the other currently available drugs; The Investigators believe that NCP112 might show a potential as an effective therapy for atopic dermatitis in animal models. Since the efficacy and safety have not been fully elucidated, new adverse reactions, unidentified from the non-clinical data, could appear later. Provided that NCP112 effectively alleviates atopic dermatitis, an intractable chronic disease, it is presumed that the expected benefits would outweigh the foreseeable risks. In the present trial, safety, including occurrences of adverse drug reactions, was thoroughly observed.~This trial was designed as a single-center, block-randomized, double-blind, placebo-controlled, single and multiple dose-ascending trial in which subjects were allocated to either topical application of NCP112 or placebo (vehicle).~The purpose of the present trial was to primarily access the safety of NCP112, the test drug of the trial, in healthy male adults prior to administer the test drug to the real patients with atopic dermatitis, the proposed indication.
To evaluate safety, tolerability and pharmacokinetics of NCP 112 after single and multiple applications on the skin of healthy male volunteers.
