E.2 Objective of the trial |
E.2.1 | Main objective of the trial |

E.4 | Principal exclusion criteria |
1. History of other significant skin disease (e.g., any skin disease requiring hospitalization), or skin manifestations of allergic illness or other dermatologic condition, except chronic moderate or severe atopic dermatitis, that would interfere with the trial assessments or compromise the patient’s safety according to the opinion of the Investigator 2. Present symptoms of other skin diseases, except chronic atopic dermatitis, that could disturb the study assessment and evaluation of the skin, according to the opinion of the Investigator 3. Current use of any active systemic medication (i.e., oral, subcutaneous, intravenous) for chronic atopic dermatitis within one month (30 days) 4. Current use of active topical medication in the planned investigational area for chronic atopic dermatitis within two weeks (14 days) 5.

Any clinically significant laboratory test result 11. Suspected current drug or alcohol abuse 12. Clinically significant illness during the 4 weeks prior to the first dose administration (as determined by the Investigator) 13. Any other condition that in the opinion of the Investigator would interfere with the evaluation of the study results or constitute a health hazard for the patient 14.

E.5 End points |
E.5.1 | Primary end point(s) |
The efficacy will be evaluated after treatment with cis-urocanic acid, placebo or comparator by Clinical Skin Assessment of erythema, oedema/papulation, oozing/crusts, excoriations, and lichenification at treatment area. Visual Analogue Scale assessment for itching (pruritus) of the treatment area will be also performed. In addition, the evaluation of the atopic eczema in the treatment area will be assessed by Physician Global Assessment, and measuring Skin Erythema and Transepidermal Water Loss at treatment area by specific non-invasive devices. The safety and tolerabilityof cis-urocanic acid will be evaluated by collecting adverse events. |
