Exclusion Criteria

Medical Conditions
1. Has reliance on high-potency topical corticosteroids to manage AD signs and symptoms.
2. Has an active systemic infection requiring systemic antibiotic treatment.
3. Has recent or anticipated concomitant use of systemic or topical therapies that might alter the course of AD in the opinion of the investigator.
4. Fitzpatrick skin phototype VI.
5. Has received prior treatment with any monoclonal antibody, TYK2 and/or JAK inhibitor.
6. Has undergone treatment for any cancer except non-melanoma skin cancers, squamous cell carcinoma, basal cell carcinoma. Participants with adequately treated or excised non-metastatic basal cell or squamous cell cancer of the skin, or cervical carcinoma in situ are allowed.
7. Active or potentially recurrent dermatologic condition other than AD that may confound evaluation in the opinion of the investigator.
8. Current or recent history (within 3 months) of severe, progressive, or uncontrolled renal, hepatic, hematological, gastrointestinal, metabolic, endocrine, pulmonary, cardiovascular, or neurological disease.
9. Hospitalization for systemic infection, chronic or acute skin infection, or use of parenteral antibiotics, antivirals, antiparasitics, antiprotozoals, or antifungals, or as otherwise judged clinically significant by the investigator.
10. Use of systemic antibiotics or systemic corticosteroids within 28 days prior to screening.
11. Use of topical antiviral agents, topical antibacterial agents, topical antifungal agents, or topical corticosteroid agents within 14 days prior to Day 1.
12. A known heritable immunodeficiency disorder.
13. Undergone significant trauma or major surgery within 3 months prior to screening.
14. Known hypersensitivity to AB-101 or any component of the hydrogel vehicle.
15. Other acute or chronic medical or psychiatric condition including recent (within the past year) or active suicidal ideation or behavior or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the participant inappropriate for entry into this study.
16. A WOCBP who has a positive urine pregnancy test within 24 hours prior to randomization or treatment allocation. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test is required.
Note: If 24 hours have elapsed between the screening pregnancy test and the first dose of study intervention, another pregnancy test (urine or serum) must be performed and must be negative for participant to start receiving study intervention.
17. Has received a live or live-attenuated vaccine within 30 days prior to the first dose of study intervention. Administration of killed vaccine and mRNA vaccines are allowed.

Prior/Concurrent Clinical Study Experience
18. Is currently participating in or has participated in a study of an investigational agent or used an investigational device within 28 days prior to the first dose of study intervention.

Diagnostic Assessments
19. Has a self-reported history of HIV, Hepatitis B or Hepatitis C infection.
