Eligibility criteria:

        Inclusion Criteria:

          1. Participants legally competent to sign and give informed consent.

          2. Adult male and female patients aged 18 to 65 years with chronic plaque psoriasis:

               1. PASI score > 10 at screening and

               2. Disease duration of ≥ 6 months at the initiation of study medication.

          3. Body Mass Index (BMI) between 18.5 and 34.9 kg/m2.

          4. Diagnosis of chronic plaque psoriasis confirmed by a dermatologist/physician.

          5. Women of childbearing potential (WCBP) must have a negative urine pregnancy test at
             Screening (Visit 1). In addition, sexually active WCBP must agree to use 2 forms of
             adequate contraception throughout the trial.

          6. Post-menopausal women with spontaneous amenorrhea for at least 12 months and serum

             and whose menopausal status is in doubt must discontinue HRT to allow confirmation of
             post-menopausal status prior to study enrollment. For most forms of HRT, at least 2 to
             4 weeks will elapse between the cessation of therapy and the blood draw; this interval
             depends on the type and dosage of HRT. Following confirmation of their post-menopausal
             status, they can resume use of HRT during the study. Sterilized women may be included.
