Summary:

      This is an open label pilot study of the impact of treatment with standard dosing of Otezla
      for 16 weeks on AM-endotype psoriasis patients, identified by elevated (>150% of normal): 1.)
      Intermediate (CD14++CD16+) monocytes, or 2.) circulating monocyte doublets, or 3.)
      circulating monocyte-platelet aggregates (MPA).

      Approximately 25 psoriasis patients with the AM-endotype will be followed during treatment
      over 16 weeks with 4 monthly individual blood draws will be enrolled. All treated psoriasis
      subjects will receive apremilast through Week 16.
