All
Target Recruitment
47
Inclusion Criteria
  • Minimum of two psoriatic plaques (i.e., one clinical target lesion and one biopsy target lesion).
  • Each of the two target lesions must have a psoriatic lesion severity sum (PLSS) of ≥6
  • Body mass index (BMI) of 18 to 38 kg/m2 (inclusive)
Exclusion Criteria
  • Prior exposure to >2 systemic biologic agents and/or small molecules including investigational therapies for the treatment of psoriasis or have not discontinued systemic biologic agents and/or small molecules anti-psoriasis therapy including investigational therapies due to lack of efficacy;
  • Subjects with significant health problems, other than having plaque psoriasis (as determined by medical history, physical examination, chest X-ray, vital signs and 12-lead ECG) that could either interfere with study evaluations or place subject at undue risk;
  • Presence of erythrodermic psoriasis, pustular psoriasis, guttate psoriasis, medication-induced psoriasis at Visit 1;
  • Conditions (e.g., clinically-significant eczema or severe acne in the target lesion area) that would interfere with study evaluations;
  • Positive quantiFERON®-TB Gold test, negative chest X-ray findings for tubercle bacillus (TB) or lack any other evidence of active or latent TB;
  • History of a clinically-significant infection (e.g., required oral antimicrobial therapy) within 4 weeks prior to Visit 2;
  • Subjects who do not have clinical laboratory test results within the normal reference ranges (i.e., are deemed not to be clinically significant) or clinically not acceptable to the Investigator;
