Primary Outcome Measures :
  1. Efficacy - Investigator Global Assessment (IGA) score [ Time Frame: 28 days ]
    Efficacy will be assessed by determining the proportion of patients who achieve an Investigator Global Assessment (IGA) score of 0 or 1 and at least a 2-point improvement in IGA at Week 4. The IGA will be assessed at every study visit. The IGA is a 5-point morphological assessment of overall disease severity and will be determined according to the following categories: 0-clear; 1-almost clear; 2-mild disease; 3-moderate disease; 4-severe disease.

  2. Efficacy - Eczema Area Severity Index (EASI) score [ Time Frame: 28 days ]
    Efficacy will be assessed by determining the proportion of patients who achieve a 50% reduction in Eczema Area Severity Index score (EASI-50) at Week 4.The EASI will be assessed at every study visit. It quantifies the severity of a patient's atopic dermatitis based on both lesion severity and the percent of body surface area affected. The EASI is a composite score ranging from 0-72 that takes into account the degree of erythema, induration/papulation, excoriation, and lichenification (each scored from 0 to 3 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 relative to the whole body.

  3. Efficacy - Peak Pruritus Numeric Rating Scale (NRS) [ Time Frame: 28 days ]
    Efficacy will be assessed as change from Baseline to Week 4 in peak pruritus as measured with the 24-hour Peak Pruritus Numeric Rating Scale (NRS). Peak Pruitus NRS will be measured at each visit. The assessment consists of a patient-rated scale of 0-10, where 0 is "No itch" and 10 is the "Worst itch possible."

  4. Efficacy - Whole body surface area (BSA) affected [ Time Frame: 28 days ]
    This exploratory endpoint will be evaluated as the change in total score from Baseline at all visits in whole body BSA (body surface area) affected. Whole body BSA affected will be assessed at every visit.


Secondary Outcome Measures :
  1. Frequency and severity of adverse events (local and systemic) [ Time Frame: 28 days ]
    Adverse events will be coded using the most current release of MedDRA® (Medical Dictionary for Regulatory Activities). The number and proportion of subjects with adverse events will be summarized by treatment, system organ class, and preferred term for all adverse events, all adverse events considered by the investigator to be related to study drug, all serious adverse events, and all adverse events leading to study drug discontinuation

  2. Plasma concentrations of RVT-501 [ Time Frame: 7 days ]
    PK samples will be collected only at the Week 1 visit in 2-11 year old patients. RVT-501 will be measured in plasma by validated assay to confirm exposure.These plasma concentrations will be listed by metabolite, subject, treatment, and time; and will be summarized by analyte and time.

  3. Plasma concentrations of M11 metabolite [ Time Frame: 7 days ]
    PK samples will be collected only at the Week 1 visit in 2-11 year old patients. The M11 metabolite will be measured in plasma by validated assay to confirm exposure. These plasma concentrations will be listed by metabolite, subject, treatment, and time; and will be summarized by metabolite, treatment and time.

Ages Eligible for Study:   2 Years to 17 Years   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Male and female pediatric patients ages 2-17 years of age with confirmed diagnosis of atopic dermatitis by Hanifin and Rajka criteria [Hanifin, 1980].
  2. Patients with atopic dermatitis covering 5% to 40% of the body surface area (BSA) and with an Investigator Global Assessment (IGA) of 2 or 3 (mild or moderate atopic dermatitis) at Baseline. Scalp, palms, and soles should be excluded from the BSA calculation to determine eligibility at Baseline.

    Note: Patients with mild disease (IGA = 2) will be limited to approximately 25% of total enrollment.

  3. Females of childbearing potential and male patients who are engaging in sexual activity that could lead to pregnancy must use the following adequate birth control methods while on study and for 2 weeks after stopping the study drug. Acceptable contraception methods are:

    • Male or male partner with vasectomy, OR
    • Male condom AND partner use of one of the contraceptive options below:
    • Spermicide;
    • Contraceptive subdermal implant that meets effectiveness criteria including a <1% rate of failure per year, as stated in the product label;
    • Intrauterine device or intrauterine system that meets effectiveness criteria including <1% rate of failure per year, as stated in the product label;
    • Oral contraceptive, either combined or progestogen alone;
    • Injectable progestogen;
    • Contraceptive vaginal ring;
    • Percutaneous contraceptive patches.

    These allowed methods of contraception are only effective when used consistently, correctly, and in accordance with the product label. The Investigator is responsible for ensuring that patients understand how to properly use these methods of contraception.

    Non-child-bearing potential is defined as pre-menarchal or pre-menopausal females with a documented bilateral tubal ligation, bilateral oophorectomy (removal of the ovaries) or hysterectomy, or hysteroscopic sterilization. Documented verbal history from the patient is acceptable.

    Patients who are abstinent are eligible, but they must agree to use of one of the birth control methods listed above if they start engaging in sexual activity that could lead to pregnancy during the study.

    Female subjects of childbearing potential must have a negative pregnancy test at Screening and Baseline (Day 0).
