Details and patient eligibility


Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by a disturbance of epidermal-barrier function that results in intensely pruritic subacute and chronic eczematous plaques. As the most common cause of chronic inflammatory skin diseases, AD is a major cause of morbidity and suffering, affecting upto 30% of children, and increasing in prevalence throughout the world. It is estimated that the direct cost of AD in the US alone ranged from $0.9 billion to $3.8 billion every year. The current therapy of AD is reactive, where the flares are treated through symptomatic management with topical corticosteroids and calcineurin inhibitors. Given that these medications have long-term side-effects, and given the chronically relapsing immunopathogenic nature of AD, there is an imperative need for safer anti-inflammatory medications. Haus Bioceuticals (Haus) has developed a topical treatment for eczema/atopic dermatitis (AD) denoted HAT1, and have demonstrated that HAT1 is safe and profoundly effective in the treatment of AD, controlling signs and symptoms in 85% of patients with AD. This study is aimed to further evaluate the potential of developing HAT1 as an integral part of AD therapy.

Full description

This study is a 17 week (119 days) randomized, double-blind, in home use study among 48 male and female subjects with moderate to severe active atopic dermatitis (AD). The study will include subjects with ages 12 - 65 years old inclusive. Group assignments will be balanced by disease severity, age, and body location of AD lesions (listed in order of importance). The study will consist of a 1 week washout period, 12 week treatment phase and a 4 week regression phase. During the treatment phase, subject will be provided one of the two test products to use twice daily on all lesions and non-lesional areas as instructed. No additional creams, lotions or soaps other than provided test products will be allowed throughout the duration of the study. Measurements, expert visual assessments and self-assessments will be taken as described below. Safety and tolerability will be evaluated by incidence of AE's (defined per CTCAE), exacerbations, application site reactions/infections, and lab evals. There will also be consumption/compliance checks and dermatological evaluations at each visit.

No Healthy Volunteers

Inclusion criteria

  • Moderate to severe atopic dermatitis as determined by Physician's Global Assessment (PGA > 3)
  • Males and females, age 12 - 65 years old inclusive

  • Has a known hypersensitivity to any corticosteroid creams.
  • Has any active infections or has used antibiotics in the past 7 days.
  • Has any physical attributes or skin conditions that might interfere with the clear visual or instrumental assessments.(i.e. cuts, sunburn, birth marks, tattoos, extensive scarring, excessive hair growth or acne)
  • Has an immunologic or infectious disease (e.g. hepatitis, tuberculosis, HIV or AIDS, lupus rheumatoid arthritis) which could place the subject at risk or interfere with the accuracy of the study results.
  • Has used any immunosuppressant drugs or immunotherapy within the past 30 days or 5 half-lives.

Trial design

Primary purpose




Interventional model

Parallel Assignment


Quadruple Blind

48 participants in 2 patient groups, including a placebo group

HAT1 topical cream
Experimental group
HAT1 medicated cream will come in a blinded tube. The research team will provide instructions for the correct application of the treatment. The medicated cream will be applied twice daily (morning and evening) at least 4 hours apart to all lesions. Treatment will continue daily until next visit. If a lesion disappears, patients will continue applying the cream twice daily to the area.
Drug: HAT1 topical cream
Vehicle cream
Placebo Comparator group
Vehicle cream will come in a blinded tube. The research team will provide instructions for the correct application of the treatment. The vehicle cream will be applied twice daily (morning and evening) at least 4 hours apart to all lesions. This will be continued daily until next visit.
Drug: Vehicle cream
