Current Primary Outcome Measures  ICMJE
 (submitted: October 28, 2016)
  • 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
  • Laboratory values [ Time Frame: 28 days ]
    Selected laboratory data will be summarized by the observed data and by the change from baseline (as appropriate) across time. Incidence of treatment emergent laboratory values that are considered clinically significantly abnormal will be summarized by treatment group.
  • Vital signs [ Time Frame: 28 days ]
    Vital signs will be measured in supine or semi-supine position after a 5 minute rest and will include systolic and diastolic blood pressure and pulse rate. Vital sign data will be listed by subject and summarized by treatment.
  • ECGs [ Time Frame: 28 Days ]
    Single 12-lead ECGs will be obtained at Screening, Day 0, Day 7, Day 28 and during follow up 7-10 days-post-dose using an ECG machine that automatically calculates the heart rate and measures PR, QRS, QT, and QTc intervals. ECG data will be listed by subject and summarized by treatment.
  • Plasma concentrations of RVT-501 [ Time Frame: 28 Days ]
    PK samples will be collected pre-dose at week 1 for all subjects. At week 4, PK samples will be collected pre-dose and within 2-4 hours post-dose. RVT-501 will be measured in plasma by validated assay in all subjects to confirm exposure. These plasma concentrations will be listed separately for adults and adolescents by metabolite, subject, treatment, and time; and will be summarized by metabolite, treatment and time. The number of percent of subjects with measurable concentration at each time point and any time during the study will be provided.
  • Plasma concentrations of M11 metabolite [ Time Frame: 28 Days ]
    PK samples will be collected pre-dose at week 1 for all subjects. At week 4, PK samples will be collected pre-dose and within 2-4 hours post-dose. The M11 metabolite will be measured in plasma by validated assay in all subjects to confirm exposure. These plasma concentrations will be listed separately for adults and adolescents by metabolite, subject, treatment, and time; and will be summarized by metabolite, treatment and time. The number of percent of subjects with measurable concentration at each time point and any time during the study will be provided.

Current Secondary Outcome Measures  ICMJE
 (submitted: October 28, 2016)
  • Efficacy - Investigators Global Assessment (IGA) [ Time Frame: 28 days ]
    The Investigator's Global Assessment (IGA) of Disease Severity will be assessed at every on-site study visit. The IGA is a global assessment of the current state of the disease. It is a 5-point morphological assessment of overall disease severity All efficacy analyses will be performed based on the ITT population by treatment and age group. The total IGA scores, changes and percent changes from baseline will be summarized by treatment group and visit. The between treatment comparisons will be performed using an ANCOVA model similar to the model used for the EASI score
  • Efficacy - Eczema Area and Severity Index (EASI) [ Time Frame: 28 Days ]
    The Eczema Area and Severity Index (EASI) will be assessed at every study visit. It quantifies the severity of a subject's atopic dermatitis based on both lesion severity and the percent of BSA affected. The total and regional EASI scores will be summarized for the actual, change from baseline and percent change from baseline. The between treatment comparisons of change and percent change from baseline will be performed by visit using an analysis of covariance model (ANCOVA)
  • Efficacy - Numeric Rating Scale (NRS) for Pruritus [ Time Frame: 28 Days ]
    NRS for Pruritus (Numerical Rating Scale) is a validated scale used to quickly assess pruritus severity. The total affected BSA and NRS for Pruritus will be analyzed similar to the EASI score. The patient reported symptoms and outcomes will be listed and summarized
Original Secondary Outcome Measures  ICMJE Same as current
Current Other Pre-specified Outcome Measures
 (submitted: October 28, 2016)
  • Patient Reported Symptoms [ Time Frame: 28 days ]
    The subject will assess burning and pruritus at the application site during clinic visits on a scale of (0) None to (3) Severe. The patient reported symptoms and outcomes will be listed and summarized.
  • Patient Report Outcomes [ Time Frame: 28 Days ]
    The Patient Oriented Eczema Measures (POEM - adult version) is a tool used for monitoring atopic dermatitis severity. It focuses on the illness as experienced by the patients. Measurements will be assessed on Day 0, Day 28 and during follow up 7-10 days post dose. The patient reported symptoms and outcomes will be listed and summarized
Original Other Pre-specified Outcome Measures Same as current

  2. Subjects with atopic dermatitis covering ≥ 3% and < 40% of the body surface area and with an Investigator Global Assessment (IGA) of 2 or 3 (mild to moderate) at baseline. Scalp, palms and soles should be excluded from the BSA calculation to determine eligibility at baseline.

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

  3. Minimum EASI score of 7 at baseline.
  4. Females of childbearing potential and male subjects and 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 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
