Phototherapy and photochemotherapy (PUVA) for AD 6. Treatment with the following before the Baseline visit: a. An investigational drug within 8 weeks or within 5 half-lives (if known), whichever is longer; b. B cell-depleting biologics, including but not limited to rituximab, within 6 months; c. Other biologics within 16 weeks or 5 half-lives (if known) , whichever is longer 7.

History of anaphylaxis as defined by the Sampson criteria40 9. Regular use (more than 2 visits per week) of a tanning booth/parlor within 4 weeks of the Screening visit 10. Uncontrolled chronic disease that might require bursts of oral corticosteroids, eg, comorbid severe uncontrolled asthma (defined by an Asthma Control Questionnaire-5 score ≥1.5 or a history of ≥2 asthma exacerbations within the last 12 months requiring systemic [oral and/or parenteral] corticosteroid treatment or hospitalisation for >24 hours) 11. Have had any of the following types of infection within 3 months of Screening or develop any of these infections before randomisation: a. Serious (requiring hospitalisation, and/or IV or equivalent oral antibiotic treatment); b. Opportunistic (as defined in Winthrop et al. 2015). NOTE: Herpes zoster is considered active and ongoing until all vesicles are dry and crusted over; c. Chronic (duration of symptoms, signs, and/or treatment of 6 weeks or longer); d. Recurring (including, but not limited to herpes simplex, herpes zoster, recurring cellulitis, chronic osteomyelitis) 12. Have a current or chronic infection with hepatitis B virus 13. Have a current infection with hepatitis C virus (ie, positive for hepatitis C RNA) 14. Have known liver cirrhosis and/or chronic hepatitis of any etiology 15. Diagnosed active endoparasitic infections or at high risk of these infections 16. Known or suspected history of immunosuppression, including history of invasive opportunistic infections (eg, tuberculosis, histoplasmosis, listeriosis, coccidioidomycosis, pneumocystosis, and aspergillosis) despite infection resolution: or unusually frequent, recurrent, or prolonged infections, per the Investigator’s judgment 17. History of HIV infection or positive HIV serology at Screening 18. In the Investigator’s opinion, any clinically significant laboratory test results from the chemistry, haematology, or urinalysis tests obtained at the Screening visit 19. Presence of skin comorbidities that may interfere with study assessments 20.

Severe concomitant illness(es) that in the Investigator’s judgment would adversely affect the patient’s participation in the study. Any other medical or psychological condition that in the opinion of the Investigator may suggest a new and/or insufficiently understood disease, may present an unreasonable risk to the study patient because of his/her participation in this clinical trial, may make patient’s participation unreliable, or may interfere with study assessments 22. Pregnant or breastfeeding women, or women planning to become pregnant or breastfeed during the study 23. Have had an important side effect to TCS (eg, intolerance to treatment, hypersensitivity reactions, significant skin atrophy, and systemic effects), as assessed by the Investigator or treating physician that would prevent further use
