Having used any of the following treatments within 4 weeks before the baseline visit, or any condition that, in the opinion of the investigator, was likely to require such treatment(s) during the first 4 weeks of study treatment:~   * Immunosuppressive/ immunomodulating drugs (e.g, systemic corticosteroids, cyclosporine, mycophenolate-mofetil, IFN-γ, Janus kinase inhibitors, azathioprine, methotrexate, etc.);~  * Phototherapy for AD~4. Treatment with topical corticosteroids (TCS) or topical calcineurin inhibitors (TCI) within 1 week before the baseline visit;~5.

NOTE: Participants might be rescreened after infection resolves;~10. Known or suspected history of immunosuppression, including history of invasive opportunistic infections (e.g, tuberculosis \[TB\], histoplasmosis, listeriosis, coccidioidomycosis, pneumocystosis, aspergillosis) despite infection resolution: or unusually frequent, recurrent, or prolonged infections, per investigator judgment;~11. History of human immunodeficiency virus (HIV) infection or positive HIV serology at screening;~12.
