* Must meet age criteria.
* Must have a diagnosis of atopic dermatitis (AD)for at least 6 months.
* Must have severity of atopic dermatitis meeting the below criteria at both Screening and Day 1:

* An IGA of 2, 3 or 4 on the vIGA scale, and;
* A BSA of =5%, and;
* An EASI score of =6.
* Must agree to use emollients.
* Must meet contraception requirements.
Minimum age
18 Years
Maximum age
75 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* Have been in a clinical trial for EDP1815 prior to signing of ICF.
* Use of phototherapy or tanning beds; systemic medications/treatments that could affect AD or its symptoms including immunosuppressive therapy (e.g., oral or injectable corticosteroids, methotrexate, azathioprine, cyclosporine, mycophenolate mofetil, JAK inhibitors, tacrolimus, and/or leukotriene inhibitor) within 4 weeks of randomization.
* Treatment with topical agents that could affect atopic dermatitis, including topical corticosteroids, topical calcineurin inhibitors (e.g., tacrolimus or pimecrolimus), or topical PDE-4 inhibitor (e.g., crisaborole) within 14 days prior to randomization.
* Clinically significant abnormalities in screening laboratory values that in the opinion of the Investigator would make a participant unsuitable for inclusion in the study. One retest is permitted within the 28-day screening window.
* Hypersensitivity to P histicola or to any of the excipients.
* Unwillingness to comply with study procedures, including follow-up, as specified by this protocol, or unwillingness to cooperate fully with the Investigator.
