Brief Summary:
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

Condition or disease Intervention/treatment Phase
Atopic Dermatitis Eczema Biological: B244 Biological: Vehicle Phase 2

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.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 122 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Randomization will be 1:1 so that equal number of patients will be treated in each Arm of the study.
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking Description:

This is a double blind study. Participants will be assigned to study treatment in accordance with the randomization schedule generated for the allocation of vehicle or B244 prior to the initiation of the trial. Randomization will be centrally-based and performed using an appropriate IWRS (an automated randomization system).

Each participant scheduled to receive investigational product (IP) will receive a randomization number at the time of randomization. The randomization number will be used to identify the study medication kit assigned to the participant and indicate the treatment to be administered to that participant.

Primary Outcome Measures :
  1. Number of Participants With Treatment-related Adverse Events as Assessed by CTCAE v4.0 [ Time Frame: Baseline to Day 42 ]
    Safety and tolerability endpoints will consist of all adverse events reporting during the study duration.


Secondary Outcome Measures :
  1. Change in Eczema Area Severity Index (EASI) Score Between the Active and Vehicle Groups [ Time Frame: Baseline to Day 28 ]
    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.


Other Outcome Measures:
  1. Change in Visual Analog Scale (VAS) Score for Pruritus Between the Active and Vehicle Group [ Time Frame: Baseline to Day 28 ]
    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.

  2. Change in the Skindex 16 Score Between the Active and Vehicle Group [ Time Frame: Baseline to Day 28 ]
    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.

  3. Change in the IGA Score Between the Active and Vehicle Groups [ Time Frame: Baseline to Day 28 ]
    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).

  4. Difference in Actigraphy Scratching Event Count Per Hour During the Night Between the Active and Vehicle Group [ Time Frame: Baseline to Day 28 ]
    Subjects were provided two Actigraphy watches (one on each wrist) to accurately monitor subject's sleep, activity, and itching patterns.

  5. Difference in Biomarkers Between Active and Vehicle Groups. [ Time Frame: Baseline and Day 28 ]
    To evaluate if B244 administration on the skin twice daily for 28 days will affect the levels of immune biomarkers.

  6. Microbial Content [ Time Frame: Baseline and Day 28 ]
    Evaluate if B244 administration on skin twice daily will affect the microbial content on collected skin swab samples.
