* Participants with:

* AtD defined by the AAD Consensus Criteria.
* Diagnosis of AtD ≥1 year.
* An IGA score ≥3.
* AtD involvement of ≥10% body surface area (BSA).
* EASI score ≥16
* Baseline pruritus numerical rating scale average score for maximum intensity of at least 3.
* Participants may have had exposure to 1 biologic therapy meeting at least 1 of the following conditions:

* Participants who stopped treatment due to non-response, partial response, loss of efficacy.
* Participants who stopped treatment due to intolerance or AEs.
* Participant with a recent history less than or equal to (≤6) months prior to the Screening visit) of inadequate response to a stable regimen of prescription topical medication.
* Participants for whom prescription topical medications are not tolerated.
* Contraceptive use by women should be consistent with local regulations regarding the methods of contraception for those participating in clinical study

Exclusion Criteria
