Eligibility criteria:

        Inclusion Criteria:

          -  Body Mass Index (BMI) 19 to 34, BMI = weight (kg)/height (m^2).

          -  Must have a diagnosis of psoriasis vulgaris (PASI >8) present for at least 1 year.
             Participants with an on-therapy PASI <=8 at Screening may be considered for inclusion.
             Participants must be discussed with the Sponsor prior to enrollment and the subject
             must have indicated that they are not satisfied with current therapy. To be included,
             participants must have a PASI >8 following washout of their current psoriasis therapy.

          -  Target lesion selected must be located on the head, trunk, arms or legs and be at
             least 10 cm^2 in size. The lesion's total numerical ratings for erythema,
             infiltration, and desquamation must be at least 6 out of the possible 12. Severity
             score for desquamation must be at least 2.

          -  Vital sign measurements (taken after ~3 minutes in a supine position) must be within
             the following ranges: oral body temperature between 35.0°C to 37.5°C; systolic blood
             pressure, 90 to 160 mm Hg; diastolic blood pressure, 45 to 90 mm Hg; pulse rate, 40 to
             100 bpm.

          -  Have stable disease (ie, off treatment PASI during Screening period and Baseline PASI
             should not differ by more than 40%).

          -  Clinical laboratory tests (CBC, blood chemistries, and urinalysis) must be within
             normal limits or clinically acceptable to the investigator/sponsor. Participants must
             have a neutrophil count of at least 2 x 10^9/L to be included.

          -  Willing to give written informed consent and able to adhere to dose and visit
             schedules.

             test. Agree to use medically accepted methods of contraception during and for an
             appropriate pre-study period while receiving protocol specified medication, and for 1

          -  Male subject must agree to use an adequate form of contraception for the duration of
             the study.

          -  At Screening, ECG conduction intervals must be within gender specific normal range
             (ie, QTc for males <430 msec and females <450 msec) or if not within the normal range,
             the values must be considered clinically insignificant by the investigator and
             sponsor.

        Exclusion Criteria:

             distribution, metabolism or excretion of any drug.
