6. Participants who agree to discontinue all agents used to treat AD from screening through the final follow-up visit.
7. Participants who have at least 1 "target lesion" that measures approximately 10 cm2 or more at screening and baseline. Lesion must be representative of the participant's disease state and not be located on the hands, feet, or genitalia.
8. Willingness to avoid pregnancy or fathering of children based on the criteria below:
a. Woman of nonchildbearing potential (surgically sterile with a hysterectomy and/or bilateral oophorectomy OR postmenopausal, defined by last menstrual period ≥ 12 months of amenorrhea before screening confirmed by FSH levels at screening) and at least 50 years of age) are exempt from pregnancy testing.
b. Woman of childbearing potential who has a negative serum pregnancy test at screening and a negative urine pregnancy test before the first dose on Day 1 and who agrees to take appropriate precautions to avoid pregnancy (with at least 99% certainty) from screening through safety follow-up (30 [+ 7] days after EOT). Permitted methods that are at least 99% effective in preventing pregnancy should be communicated to the participant and their understanding confirmed.
c. Adolescents who are prepubescent.
d. Man who agrees to take appropriate precautions to avoid fathering children (with at least 99% certainty) or from sperm donation from screening through 90 days after treatment with ruxolitinib cream.

E.4 | Principal exclusion criteria |
1. Participants who have an unstable course of AD (spontaneously improving or rapidly deteriorating) as determined by the investigator in the 4 weeks prior to baseline.
2. Participants with concurrent conditions and history of other diseases:
a. Immunocompromised (eg, lymphoma, acquired immunodeficiency syndrome, Wiskott-Aldrich syndrome).
b. Chronic or acute infection requiring treatment with systemic antibiotics, antivirals, antiparasitics, antiprotozoals, or antifungals within 2 weeks before baseline.
c. Active acute bacterial, fungal, or viral skin infection (eg, herpes simplex, herpes zoster, chicken pox) within 1 week before baseline.
d. Any other concomitant skin disorder (eg, generalized erythroderma such as Netherton syndrome), pigmentation, or extensive scarring that, in the opinion of the investigator, may interfere with the evaluation of AD lesions or compromise participant safety.
e. Presence of AD lesions only on the hands or feet without prior history of involvement of other classical areas of involvement such as the face or the folds.
f. Other types of eczema.
3. Any serious illness or medical, physical, or psychiatric condition(s) that, in the investigator's opinion, would interfere with full participation in the study, including administration of study drug and attending required study visits; pose a significant risk to the participant; or interfere with interpretation of study data. For example:
a. Clinically significant or uncontrolled cardiac disease, including unstable angina, acute myocardial infarction within 6 months from Day 1 of study drug administration, New York Heart Association Class III or IV congestive heart failure, and arrhythmia requiring therapy or uncontrolled hypertension (blood pressure > 150/90 mmHg) unless approved by medical monitor/sponsor.
b. Participants with a history of malignancy in the 5 years preceding enrollment into this study, except for adequately treated, nonmetastatic malignancies.
c. Low hemoglobin (< 10 g/dL).
d. Severe renal disease on dialysis (serum creatinine > 2 mg/dL).
e. Current and/or liver disease history, including known hepatitis B or C, with hepatic or biliary abnormalities.
4. Participants using any of the following treatments within the indicated washout period before baseline:
a. 5 half-lives or 12 weeks, whichever is longer – biologic agents (eg, dupilumab).
b. 4 weeks – systemic corticosteroids or adrenocorticotropic hormone analogs, cyclosporin, methotrexate, azathioprine, or other systemic immunosuppressive or immunomodulating agents (eg, mycophenolate or tacrolimus).
c. 2 weeks – immunizations and sedating antihistamines, unless on long-term stable regimen (nonsedating antihistamines are permitted).
d. 1 week – use of other topical treatments for AD (other than bland emollients), such as corticosteroids, calcineurin inhibitors, coal tar (shampoo), antibiotics, antibacterial cleansing body wash/soap. Diluted sodium hypochlorite "bleach" baths are allowed as long as they do not exceed 2 baths per week and their frequency remains the same throughout the study.
5. Participants who have previously received JAK inhibitors, systemic or topical.
6. Ultraviolet light therapy or prolonged exposure to natural or artificial sources of UV radiation (eg, sunlight or tanning booth) within 2 weeks prior to baseline and/or intention to have such exposure during the study, which is thought by the investigator to potentially impact the participant's AD.
7. Positive serology test results at screening for HIV antibody.
8. Liver function tests: AST or ALT ≥ 2 × ULN; alkaline phosphatase and/or bilirubin > 1.5 × ULN (isolated bilirubin > 1.5 × ULN is acceptable if bilirubin is fractionated and direct bilirubin < 35%).
9. Pregnant or lactating participants, or those considering pregnancy.
10. History of alcoholism or drug addiction within 1 year before screening or current alcohol or drug use that, in the opinion of the investigator, will interfere with the participant's ability to comply with the administration schedule and study assessments.
11. Current treatment or treatment within 30 days or 5 half-lives (whichever is longer) before baseline with another investigational medication or current enrollment in another investigational drug Protocol.
12. Participants who, in the opinion of the investigator, are unable or unlikely to comply with the administration schedule and study evaluations.
13. Participants who are committed to a mental health institution by virtue of an order issued either by the judicial or the administrative
authorities.
