Evaluating the Efficacy and Tolerability of Ceradan Advanced Cream in the Treatment of Children With Atopic Dermatitis

Atopic Dermatitis Eczema

Atopic dermatitis is the most common chronic inflammatory skin condition worldwide and in Singapore. There is a significant impact on the quality of life as well as psychosocial burden on the patient and family. Emollients are one of the cornerstones in the treatment of atopic dermatitis and are frequently prescribed with topical anti-inflammatories such as topical corticosteroids or topical calcineurin inhibitors to be used during active flares. Emollients that have additional anti-inflammatory properties may be able to reduce usage of topical corticosteroids or calcineurin inhibitors. In this study the investigators hope to evaluate the use of a patented ceramide dominant emollient which sustainably lowers the skin pH (Ceradan ® Advanced Cream, Hyphens Pharma, Singapore) with a commonly prescribed emollient in Singapore (Basic Aqua Cream, ICM Pharma, Singapore) for the treatment of moderate atopic dermatitis in children and adolescents.

This is a single center, randomized, double-blind, controlled study comparing a patented ceramide dominant emollient which sustainably lowers the skin pH with a standard commercial emollient for the treatment of moderate atopic dermatitis over two weeks. Subjects will be concomitantly treated with a low-potency topical steroid (Desonide lotion, Galderma, France) at the start of the trial to minimize any underlying skin inflammation for a more comparable baseline skin state. Investigators and subjects are blinded to the treatment allocation. Subjects will be randomized using a random number sequence in a 1:1 ratio between the two arms. The study administrator will keep this information concealed in an opaque, sealed envelope to be disclosed upon completion of the trial. Allocation is secure and concealed with no further changes to be made. Subjects will be dispensed a mild potency topical steroid (Desonide lotion, Galderma, France) and 480g of emollient (Ceradan ® Advanced Cream, Hyphens Pharma, Singapore or Basic Cream, ICM Pharma, Singapore) for the duration of the trial. The amount of steroid dispense would depend on the weight of the subject (\<20kg: 1 bottle, 20-40kg: 2 bottles, \>40kg: 3 bottles). Emollients will be dispensed in identical, unmarked containers. Subjects should not wash the test areas with water or cleansing products (e.g. soap, body cleansers, and bath and shower products) within the 12 hours prior to scheduled visit at 2 weeks (visit 1) for assessment. Subjects will be instructed to use mild potency topical steroid (Desonide lotion, Galderma, France), twice a day to all affected areas with eczema for the first three days of the trial. The topical steroid supplied can be used after the initial period of treatment as needed and subjects will be asked to record down the areas that treated and the duration of treatment. Subjects will be asked to use the emollient provided twice a day on the face, trunk, and limbs. This is to be used after application of topical steroids, where applicable. Subjects will be asked to not apply any other topical leave-on products (e.g. creams, lotions, ointments) on the test areas, apart from those products dispensed for this trial during the entire duration of the study. Subjects will be asked to apply the emollient on the test areas the last time within 3-12 hours before the scheduled final visit (visit 1). Dispensed product will be weighed and recorded prior to the start of the trial and on completion of the trial to assess the compliance and amount of product used. Schedule of Visits Assessment at baseline (Visit 0) includes: * Baseline demographics (age, race and gender) * Past medical history and drug allergies * Family and personal history of atopy * Atopic dermatitis history (duration of illness, areas affected, treatments used including type, frequency of use and amount of steroids/emollients used 1 month before enrollment) * EASI score * SCORAD score * Skin pH (HI99181 pH Meter for Skin, Hanna Instruments Inc., Singapore) * Transepidermal water loss (TEWL) (Delfin Technologies) * Stratum corneum (SC) hydration (Delfin Technologies) * Peak pruritus NRS (numerical rating scale) score * Patient-Oriented Eczema Measure (POEM) score * Patient Eczema Severity Time (PEST) score \[11\] via iControl Eczema Application (Hyphens Pharma, Singapore) * Children's Dermatology Quality of Life (C-DLQI) score * Teenagers' Quality of Life (T-QoL©) score * Dermatitis Family Impact (DFI) Questionnaire Assessment after 2 weeks (Visit 1) includes: * EASI (Eczema Area and Severity Index) score * SCORAD (Severity Scoring of Atopic Dermatitis) score * Skin pH (HI99181 pH Meter for Skin, Hanna Instruments Inc., Singapore) * TEWL (Delfin Technologies) * SC hydration (Delfin Technologies) * Peak pruritus NRS (numerical rating scale) score * Patient-Oriented Eczema Measure (POEM) score * Patient Eczema Severity Time (PEST) score via iControl Eczema Application (Hyphens Pharma, Singapore) * Children's Dermatology Quality of Life (C-DLQI) score * Teenagers' Quality of Life (T-QoL©) score * Dermatitis Family Impact (DFI) Questionnaire In the event of a severe exacerbation of atopic dermatitis, Visit 1 will be brought forward to allow the patient to return for an assessment and any rescue or additional treatment as required. The assessment measures planned after 2 weeks will be done at this visit as well. Data Collection Methods Personal data will be treated as strictly confidential. Data will be collected using a secured encrypted database and anonymized. Data will be collected at baseline visit and follow up visit 2 weeks later. Further clarification will be made to the patient and/or family over phone call if required. Potential difficulties and risks * Adverse reactions and/or contact dermatitis to emollients or its constituents * Burning or stinging sensation * Increased itch * Localized skin infections * Exacerbation of atopic dermatitis * Slips and falls
