Study the Safety and Efficacy of DBI-001 Gel Versus Aqueous Gel
Study Details
Study Description
Brief Summary
This is a randomized, observer blinded, Aqueous Gel-controlled, within-patient, bilateral comparison trial examining the effect of daily application for 4 weeks of DBI-001 Gel vs. Aqueous Gel on the clinical Atopic Dermatitis Severity Index (ADSI) scores and the abundance of Staphylococcus aureus of comparable bilateral target sites of Atopic Dermatitis (AD), as well as signs and symptoms of local tolerability on treated sites in subjects.

Outcome Measures
Primary Outcome Measures
- Change from baseline in Atopic Dermatitis Score Index score [42 days of participation]
Change from baseline in Atopic Dermatitis Score Index score at days 7, 14, 21, 28, 35 and 42 of sites treated with DBI-001 Gel or Aqueous Gel. The minimum value is 0 and the maximum value is 15 representing the observed disease level.
- Change from baseline in individual signs and symptoms of Atopic Dermatitis [42 days of participation]
Change from baseline in individual signs and symptoms of Atopic Dermatitis (components of ADSI score) at days 7, 14, 21, 28, 35, and 42 of sites treated with DBI-001 Gel or Aqueous Gel. The minimum value is 0 and the maximum value is 0 the subject's self reported observation on local tolerability.
Secondary Outcome Measures
- Number of subjects with treatment-related adverse events [42 days of participation]
Safety
- Molecular diagnostic qPCR comparison of DBI-001 drug product with aqueous gel [42 days of participation]
Antimicrobial efficacy
- Change in colony forming units [42 days of participation]
Antimicrobial efficacy
- Proportion of subjects with a greater decrease in Atopic Dermatitis Severity Index [42 days of participation]
Observe proportion of subjects with a greater decrease in Atopic Dermatitis Severity Index for sites treated with DBI-001 Gel or Aqueous Gel.
- Change in colony forming units after using DBI-001 drug product or aqueous gel [42 days of participation]
Antimicrobial efficacy
- Number of subjects with treatment-related changes in the immune system response after using DBI-001 drug product or aqueous gel as assessed by changes in the stratum corneum. [42 days of participation]
Clinical Efficacy
Eligibility Criteria
Criteria
Inclusion Criteria:
-
- Ability to understand, agree to, and sign the study Informed Consent. If the patient is unable to provide consent for him/herself, the patient's legally authorized representative may provide written consent.
-
- A signed Health Information Portability and Accountability Act (HIPAA) authorization form which permits the use and disclosure of subject's individually identifiable health information.
-
- Male or Female Subjects of any race 12 - 65 years of age.
-
- Physician diagnosed clinically stable AD according to the criteria of Hanifin and Rajka with symmetrical bilateral target lesions (Hanifin and Rajka 1980). Lesion on each arm or leg must have an Atopic Dermatitis Severity Index (ADSI) ≥6. The 2 sites need to be comparable anatomically symmetrical sites. It will be in the opinion of the Investigator based on subject's medical history whether the lesions are clinically stable.
-
- Female patients of child-bearing potential must use at least one method of birth control that results in a low failure rate (i.e., less than 1% per year) when used consistently and correctly such as implants, injectables, combined oral contraceptives, some intrauterine devices (IUDs), sexual abstinence or vasectomized partner for the duration of study participation.
-
- Technical ability and willingness to apply test articles during telemedicine visits with the study staff and unsupervised on weekends.
-
- Willingness to discontinue use of systemic AD treatments and topical treatments to the target areas for the duration of the study unless specifically permitted by the Investigator.
-
- Willingness to comply with test site restriction for 12 hours prior to all office visits including the Baseline visit and for 12 hours after each treatment application.
These treatment site restrictions include:
-
No washing of test sites with any cleansers or soaps at any time from the Baseline visit to completion of the Day 42 Follow up Visit. Water passing over the areas during showering is acceptable.
-
No rubbing the test sites with a washcloth, towel, luffas. Pat dry after showering is acceptable.
-
No recreational activities in chlorinated or chemically treated water such as swimming pools, hot tubs, and spas.
-
No tight or form fitting clothing covering the treatment areas.
-
No sunbathing or use of suntan parlors or tanning beds.
-
If participating in physical activities resulting in heavy perspiration only pat dry test site areas with towel if needed.
-
Any activity that in the opinion of the investigator might alter the quality of the samples collected or risk removal of the test article.
-
- Willingness to undergo the following washout periods:
-
Washout of 2 weeks prior to the Baseline visit for topical treatments used on the two treatment target sites, including but not limited to: antibacterial products, anti-inflammatories (e.g., corticosteroids, tacrolimus, Pimecrolimus). Other than the two sites on the arms or legs, topical medications may be used before/during the duration of the study. Subjects will be provided 1% hydrocortisone for treating non-target areas during the trial.
-
Washout of 4 weeks prior to the Baseline visit for systemic treatments for AD, including but not limited to corticosteroids (oral or intramuscular injections), systemic immunomodulators or immunosuppressive (e.g., methotrexate, cyclosporine, hydroxychloroquine), antibiotics (oral or injected, if required to treat a medical condition short duration of oral antibiotics (≤10 days) are permitted after randomization)
-
Washout of 2 weeks prior to the Baseline visit for bleach baths.
-
Washout of 2 weeks prior to the Baseline visit for phototherapy.

-
- AIDS or AIDS related complex by medical history.
-
- Known or suspected immune suppressive medications or diseases or any condition that in the opinion of the investigator would increase the subject's susceptibility to opportunistic infections. 11. Treatment with systemic immune modulating or anti-inflammatory biologics agents within 16 weeks of Baseline Visit.
-
- Poorly controlled diabetes mellitus Type I or II by medical history.
-
- Peripheral vascular disease based on medical history.
