Read the detailed description

This is a Prospective, Vehicle Controlled, Double Blind, Multicenter, Randomized Phase II trial, comparing the effect of twice daily B244 application for 28 days vs vehicle application on treatment of mild to moderate AD

At Screening and Baseline, all subjects must have atopic dermatitis, as defined by the Hanifin and Rajka criteria, which involves a minimum of 10% and a maximum of 30% body surface area, EASI score of 10 to 21 and pruritus visual analogue scale scores of ≥ 5 points on the VAS scale (at least moderate).

The total duration of the study will be approximately 9 weeks. Participants will report for a Screening visit and if all inclusion criteria are met, subjects will go through a two week washout phase before reporting for a Baseline visit.

Subjects will come in for visits at Day 14 (Week 2), Day 28 (Week 4). A final visit will be conducted at Day 42 (Week 6).

Efficacy will be assessed using Atopic Dermatitis Area and Severity Index (EASI) and Visual Analog Scale (VAS).

Blood and urine samples will be collected for standard safety laboratory tests and effect of the drug on inflammatory biomarkers. Participant's safety will be monitored throughout the study.

Investigators plan to enroll approximately 130 total patients.

Randomization will be 1:1 so that equal number of patients will be treated in each Arm of the study.

What researchers measure

Primary outcomes

  1. Number of Participants With Treatment-related Adverse Events as Assessed by CTCAE v4.0

    Safety and tolerability endpoints will consist of all adverse events reporting during the study duration.

    Time frame: Baseline to Day 42

Secondary outcomes

  1. Change in Eczema Area Severity Index (EASI) Score Between the Active and Vehicle Groups

    EASI is a validated tool used to measure the severity and extent of atopic dermatitis where clinical investigators assess the presence and severity of erythema, edema/papulation, excoriation, and lichenification (score 0-3: none=0, mild=1, moderate=2, severe=3, half-points allowed) and area of involvement (score 0-6: 0=0% involvement, 1=1-9% involvement, 2=10-29% involvement, 3=30-49% involvement, 4=50-69% involvement, 5=70-89% involvement, 6=90-100% involvement) across head and neck, trunk (including the genital area), upper extremities, and lower extremities (including the buttocks). The EASI score can range from 0.0to 72.0 with increments of 0.1 and higher scores representing a greater severity of atopic dermatitis.

    Time frame: Baseline to Day 28

Other outcomes

  1. Change in Visual Analog Scale (VAS) Score for Pruritus Between the Active and Vehicle Group

    VAS (Visual Analog Scale) was performed as a measure of pruritus. The VAS is composed of a 10-cm line divided into a scale from 0 to 10, and subjects were to indicate the score that best represented the intensity of their itching over the 24-hour period before each visit where a higher score indicated greater severity in pruritus.

    Time frame: Baseline to Day 28

  2. Change in the Skindex 16 Score Between the Active and Vehicle Group

    The Skindex 16 questionnaire was assigned to subjects to examine the relationship between the subject's skin health and quality of life. Subjects scored 16 questions from 0 to 6 (0=never bothered, 6=always bothered). Total scores could range between 0 to 96, where a higher score is associated with a worse quality of life.

    Time frame: Baseline to Day 28

  3. Change in the IGA Score Between the Active and Vehicle Groups

    IGA (Investigator's Global Assessment) was used to assess the overall diseases severity on a scale of 0 to 4 (0=clear, 1=almost clear, 2=mild disease, 3=moderate disease, and 4=severe disease).

    Time frame: Baseline to Day 28

  4. Difference in Actigraphy Scratching Event Count Per Hour During the Night Between the Active and Vehicle Group

    Subjects were provided two Actigraphy watches (one on each wrist) to accurately monitor subject's sleep, activity, and itching patterns.

    Time frame: Baseline to Day 28

  5. Difference in Biomarkers Between Active and Vehicle Groups.

    To evaluate if B244 administration on the skin twice daily for 28 days will affect the levels of immune biomarkers.

    Time frame: Baseline and Day 28

  6. Microbial Content

    Evaluate if B244 administration on skin twice daily will affect the microbial content on collected skin swab samples.

    Time frame: Baseline and Day 28
