E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the ability of DEXERYL to prevent flares after treatment of a previous flare by a topical corticosteroid. |
|
E.2.2 | Secondary objectives of the trial |
To assess the time to first flare, the number of flares
To evaluate the consumption of topical corticosteroid
To evaluate DEXERYL effect on the skin dryness and pruritus
To evaluate DEXERYL on the subjective perception of the skin
To document the clinical, local and systemic, safety of DEXERYL |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients, male or female children, presenting with the following criteria may be included (V1):
Age between 2 and 6 years included,
- Presenting with atopic dermatitis according to the diagnostic criteria of the UK Working Party,
- Who has presented within the previous 6 months at least one duly documented flare treated by corticosteroids,
- Who present a current flare,
- Whose objective SCORAD score is [15-40] (grade 3) at inclusion,
- Whose parent(s) or guardian(s) has given his/her (their) written consent for their child's participation in the study,
- Whose parent(s) or guardian(s) is (are) cooperative with regard to compliance with study-related constraints,
- Affiliated to a social security system, or is a beneficiary (if applicable in the national regulation).
After treatment of the current flare, patients should have for randomization (V2):
- Objective SCORAD score is < 15,
- No lichenification, no excoriation, no oozing/crusts, no oedema/papulation,
- Erythema intensity < 1 (residual erythema area ≤ 10% of extent),
- Xerosis intensity> 1,
- No pruritus, no sleep disorders (< 1 on VAS of SCORAD).
If lesions are not cleared in 21 days, patient cannot be randomized. |
|
E.4 | Principal exclusion criteria |
* Criteria related to pathologies
- Severe form of atopic dermatitis requiring either systemic corticosteroid treatment and/or antibiotic or antiviral treatment and/or hospitalisation,
- Primary bacterial, viral, fungal or parasitic skin infection,
- Ulcerated lesions, acne or rosacea,
- Dermatological disease other than atopic dermatitis which could interfere with the assessment,
- Immunosuppression,
- History of serious disease considered by the investigator hazardous for the patient or incompatible with the study.
* Criteria related to treatments
- Use of oral corticosteroids or immunosuppressants during the last 14 days,
- Use of topical corticosteroids during the last 7 days,
- Use of systemic or local antibiotics on the lesions during the last 7 days,
- Use of non-steroid anti-inflammatory drugs or antihistamines during the last 7 days,
- Regular use of food supplements that could, in the opinion of the investigator, modify skin properties (e.g. synbiotics),
- History of hypersensitivity or intolerance to one of the components of the tested or associated products, or to cosmetics.

E.5 End points |
E.5.1 | Primary end point(s) |
Percentage of patients with at least one flare assessed by the investigator over the 12 weeks of treatment
In case of occurrence of flare, the patient should be seen as soon as possible by the investigator to confirm the flare, and if necessary to prescribe appropriate treatments.
A flare will be defined as following : measurable increased extent or intensity of lesions in less than 2 weeks under continued treatment (in this case: emollient or no emollient), corresponding to a significant increase (> 25%) in medical score (SCORAD or last PO-SCORAD) or to the introduction of a new line of therapy (topical corticosteroid). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
• Time to first flare assessed by the investigator over the 12 weeks of treatment
• Number of patients in complete remission defined as a period without flare of at least 8 weeks without anti-inflammatory treatment (avoidance of irritants / allergens and emollients not included)
• Number of patients needing corticosteroids or immunosuppressants over the 12 weeks of treatment
• Consumption of corticosteroid: number of days of application, weight of corticosteroid used
• Xerosis score (from SCORAD) over the 12 weeks of treatment
• Pruritus score (VAS from SCORAD) over the 12 weeks of treatment
• Sleep loss score (VAS from SCORAD) over the 12 weeks of treatment
• SCORAD and objective SCORAD scores assessed by the investigator at every visit over the 12 weeks of treatment
• PO-SCORAD (Patient Oriented SCORAD) score assessed twice weekly by the parents over the 12 weeks of treatment
• IGA (Investigator Global Assessment) assessed by the investigator at every visit over the 12 weeks of treatment
• POEM score (Patient-Oriented Eczema Measure) assessed weekly by parents over the 12 weeks of treatment
• Assessment of the local tolerability (examination of the skin) and the systemic safety (general clinical examination and reported adverse events).
• Overall assessment of treatment use by the parents on a 4 point scale at 12th week (only for patients treated by one of 2 emollients). |
