E.2.1 | Main objective of the trial |
The primary objective will be to evaluate the benefit of the association of the product RV4421A BS0042 with a moderately potent topical corticosteroid compared with the moderately potent topical corticosteroid alone, in improvement of Atopic Dermatitis in adults, measured by the reduction of L-SCORAD at Day 3 (D3). |
|
E.2.2 | Secondary objectives of the trial |
• To evaluate the benefit of the association of the product RV4421A BS0042 with a moderately potent topical corticosteroid compared with the moderately potent topical corticosteroid alone in:
o improvement of clinical and functional signs of Atopic Dermatitis
o improvement of the skin instrumental parameters of Atopic Dermatitis
• To evaluate the effect of a 2-week maintenance period of product RV4421A BS0042 twice daily application in:
o improvement of clinical and functional signs of Atopic Dermatitis
o improvement of the skin instrumental parameters of Atopic Dermatitis
o time to relapse defined as a need of a treatment therapy and/or skin care product application
• To assess the tolerance of the product RV4421A BS0042 alone, and in association with a moderately potent topical corticosteroid, under dermatological control
• To evaluate the patients global satisfaction as regards to the use of the tested product RV4421A BS0042
• To obtain illustrative photographs

E.5 End points |
E.5.1 | Primary end point(s) |
The primary criterion is the L-SCORAD index assessed independently on both study arms or on both popliteal fossa by the investigator on a scale ranged from 0 to 18, at Visit 2 (D3). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
• The L-SCORAD index will be calculated by the investigator independently on both study arms or popliteal fossa on a scale ranged from 0 to 18, at visits V1, V3, V4 and V5
• Each of the six objective signs of the SCORAD will be rated from 0 (absent) to 3 (severe) independently on both study arms or popliteal fossa by the investigator, at all visits.
• The L-IGA (local investigator global assessment) score will be assessed by the investigator independently on both study arms or popliteal fossa on a 6-point scale ranged from 0 (clear) to 5 (very severe disease), at all visits.
• The pruritus intensity will be evaluated by the patient independently on both study arms or popliteal fossa on a visual analog scale from 0 to 10, at each time and in case of lesions worsening during the 2nd period.
• The L-PGA (local patients global assessment) will be evaluated by the patient independently on both study arms or popliteal fossa on a 5-point scale, at each time and in case of lesions worsening during the 2nd period in comparison to Atopic Dermatitis intensity on study arms or popliteal fossa at baseline
• Each of the six objective signs of the PO-SCORAD (patient oriented SCORAD) will be rated from 0 (absent) to 3, independently on both study arms or popliteal fossa by the patient, at each time and in case of lesions worsening during the 2nd period.
• The L-PO-SCORAD (local patient oriented SCORAD) index will be calculated by the patient independently on both study arms or popliteal fossa on a scale ranged from 0 to 18, at each time and in case of lesions worsening during the 2nd period.
• TEWL (transepidermal water loss) on a target lesion of each study arm or popliteal fossa will be measured by Aquaflux at each visit
• The time to Atopic Dermatitis relapse will be evaluated during the maintenance period (2 weeks), during which the associated product will not be applied anymore.
• The percentage of flares occurred at the end of the maintenance period (D24) will be evaluated for each treatment arm (arm or leg with RV4421A BS0042 and arm or leg with no product application), two weeks after the end of associated product applications.
• Patient’s global satisfaction as regards to the use of the test product RV4421A BS0042 will be assessed by the patient at the end of the study (at V4 or within 2 days before V5 or at V5) through a specific questionnaire.
