Summary:

      The primary objective of the study is to assess the efficacy of dupilumab on skin lesions in
      patients with atopic hand and foot dermatitis.

      The secondary objectives of the study are:

        -  To assess the efficacy of dupilumab on various other domains (pruritus, pain, sleep
           loss, health related QoL, work life impairment) in patients with atopic hand and foot
           dermatitis

        -  To evaluate the safety and tolerability of dupilumab administered to patients with
           atopic hand and foot dermatitis

        -  To evaluate systemic exposure and immunogenicity of dupilumab in patients with atopic
           hand and foot dermatitis

        Key Exclusion Criteria:

          -  Treatment with dupilumab in the past

          -  Patients with a positive patch test reaction that are deemed to be clinically relevant
             as the current cause of the hand and foot dermatitis

          -  Patients with documented exposure to irritants believed to be a predominant cause of
             the current hand and foot dermatitis

          -  Treatment with systemic corticosteroids or non-steroidal immunosuppressive drugs
             within 4 weeks prior to baseline

          -  Known history of HIV/HBV/HCV infection

             the patient's participation in this study

          -  Women of childbearing potential (WOCBP) who are unwilling to practice highly effective
             contraception prior to the initial dose/start of the first treatment and during the
             study
