The study's objective is to confirm that RHT-3201 reduces the signs and symptoms of moderate atopic dermatitis determined by SCORAD, in patients aged 1 to 12 years, as compared to placebo. It will also be examined if the RHT-3201 treatment, as compared to placebo, reduces the quantity of topical steroids used to treat disease flares

| Change from baseline in SCORAD subjective score | Subscales: Eczema Spread (A): 0 - 20 Eczema Intensity (B): 0 - 63 Subjective Symptoms (C): 0 - 20 Total = (A/5) + (Bx7/2) + C Total: 0 - 103 (Higher values represent a worse outcome) "Subjective" SCORAD, which is composed of part C of the SCORAD | after 4, 8 and 12 week treatment |
| Change from baseline in Eczema Area and Severity Index (EASI) | The Eczema Area and Severity Index (EASI) quantifies the severity of a subject's AD based on both severity of lesion clinical signs and the percent of body surface area (BSA) affected. EASI is a composite scoring of the degree of erythema, induration/papulation, excoriation, and lichenification (each scored separately) for each of four body regions, with adjustment for the percent of BSA involved for each body region and for the proportion of the body region to the whole body. Scores range is 0-72 and Higher values represent a worse outcome | after 4, 8 and 12 week treatment |
| Proportion of participants achieving at least a 50%, 75% reduction in EASI | EASI 50 or EASI 75 responder rates, defined as proportions of patients achieving 50% or more and 75% or more improvement in EASI score from baseline, respectively. | after 12-week treatment |
| Change in Investigator Global Assessment (IGA) from baseline to Week 4, 8 and 12 | The IGA is an instrument used in clinical trials to rate the severity of the subject's global AD and is based on a 6-point scale ranging from 0 (clear) to 5 (Very severe disease). | after 4, 8 and 12 week treatment |
| Proportion of participants achieving IGA of 0 or 1 with at least two grades of reduction | The IGA is an instrument used in clinical trials to rate the severity of the subject's global AD and is based on a 6-point scale ranging from 0 (clear) to 5 (Very severe disease). | after 12-week treatment |
| Change from baseline in numeric rating scale (NRS) | Participant-rated pruritus score of lesions and insomnia rated the severity of pruritus suffered in the past 24 hours on an 11-point Numeric Rating Score (NRS) where 0 is no pruritus and 10 is most severe possible pruritus. | after 4, 8 and 12 week treatment |
| Change from baseline in immunologic blood marker (Total immunoglobulin E (IgE), Eosinophil counts) | Measuring total IgE and Eosinophil counts in serum (total IgE (KU/L), Eosinophil counts (cells/uL)) | after 12-week treatment |
| Change from baseline n Children's Dermatology Life Quality Index (CDLQI) or Infants Dermatitis Quality of Life index (IDQoL) | The CDLQI is a 10-item questionnaire that measures the impact of skin disease on participant's quality of life. Each question is evaluated on a 4-point scale ranging from 0 (not at all) to 3 (very much); where higher scores indicate more impact on quality of life. The DLQI total score ranges from 0 (not at all) to 30 (very much): 0-1 = no effect at all on the participant's life; 2-6 = small effect on the participant's life; 7-12 = moderate effect on the participant's life; 13-18 = very large effect on the participant's life; 19-30 = extremely large effect on the participant's life. Higher scores indicate more impact on quality of life of participants. | after 4, 8 and 12 week treatment |
| Change from baseline in Dermatology Family Impact (DFI) | The DFI is a 10-item disease questionnaire that measures the impact of having a child with AD on family quality of life. It is completed by parent/legal guardian of the child (affected by AD), based on recall over the past week. Each question is scored on a 4-point scale ranging from 0 (good) to 3 (worst), where higher scores indicated worst quality of life of family. The DFI total score is the sum of individual scores of the 10 questions and ranges from 0 (good) to 30 (worst), where higher DFI scores indicated worst quality of life of family. | after 4, 8 and 12 week treatment |
| Quantity of emollients | Measuring quantity of emollients at every visits | after 4, 8 and 12 week treatment |
| Proportion of participants using topical corticosteroids and quantity of topical corticosteroids | Proportion of participants using topical corticosteroids during study period and measuring quantity of topical corticosteroids during study | after 4, 8 and 12 week treatment |
| Number of days with or without topical corticosteroids | Number of days with or without topical corticosteroids during study period | after 4, 8 and 12 week treatment |
| Drop-out rate using topical corticosteroids | Drop-out rates due to use topical corticosteroids | after 4, 8 and 12 week treatment |
| Incidence of adverse event (AE)'s | AE will be assessed by incidence of AE, abnormalities in vital sign assessments, clinical laboratory assessments, and physical exams Incidence of treatment emergent AEs. An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. AEs are classified according to the severity in 3 categories a) mild (AEs does not interfere with participant's usual function); b) moderate (AEs interferes to some extent with participant's usual function) and c) severe (AEs interferes significantly with participant's usual function). | From Baseline through Week 12 (entire study) |
