prior to screening and has confirmed AD (Hanifin and Rajka criteria for AD (Hanifin
and Rajka, 1980).

- AD that affects greater than or equal to' 10% body surface area as assessed by EASI at
screening and on day 1.

- An IGA score of greater than or equal to 3 at screening and on day 1.

- An EASI score of greater than or equal to 16 at screening and on day 1.

at least the 7 days immediately prior to the first dose of investigational product

- Documented recent history (within 12 months before the screening visit) of inadequate
response totreatment with topical TCS or subjects for whom topical treatments are
otherwise medically inadvisable (ie, because of important side effects or safety
risks).

- Inadequate response is defined as failure to achieve and maintain remission or a
low disease activity state (comparable to IGA 0 = clear to IGA 2 = mild) despite
treatment with a daily regimen of TCS of medium or higher potency (with or
without TCI as appropriate).
