             specific procedures

          -  Diagnosis of moderately severe plaque psoriasis that has been moderately stable for 6
             months and failed at least 1 line of systemic or phototherapy and is a candidate for
             additional systemic therapy

          -  PASI of ≥ 12 within the 24-hour period prior to the first dose of study drug

          -  At least 10% of body surface area affected by plaque psoriasis within the 24-hour
             period prior to the first dose of study drug

          -  Willing to avoid tanning devices

          -  Willing to forgo other systemic and topical treatments for psoriasis during the course
             of the study

          -  Adequate bone marrow function: absolute neutrophil count > 1500/mm^3; hemoglobin > 9.0
             g/dL; platelets > 100,000/mm^3

             the 24-hour period prior to the first dose of study drug

          -  Agree to use a highly effective method of birth control (< 1% per year failure rate)
             during the study and for 1 month after the termination of the study. Effective birth
             control included implants, injectables, combined oral contraceptives, some IUDs,
             sexual abstinence, or vasectomized partner

          -  Willing to complete all study measurements and assessments in compliance with the
             protocol

        Exclusion Criteria:

          -  Non-plaque or drug-induced (antimalarials, lithium) psoriasis (If subject is taking
             angiotensin II receptor blockers or beta blockers doses had to be stable for 6 months
             prior to study entry)

          -  Use of corticosteroid or immunosuppressive therapy within 4 weeks prior to study entry
             except for Class 5 or weaker topical corticosteroids or immunosuppressive therapies to
             the face, groin, or scalp.

          -  Use of methotrexate, acitretin, or cyclosporine within 4 weeks prior to study entry

          -  Use of phototherapy within 4 weeks prior to study entry

          -  Use of biologic therapies, including antibodies to IL-17, within 3 months prior to
             study entry

          -  Concomitant condition requiring treatment with moderate to high dose steroids in the
             12 weeks prior to screening

          -  Viral, fungal, or bacterial skin infection

          -  Pregnant or lactating

          -  History of gastrointestinal (GI) surgery including bariatric surgery, or any GI
             condition that might interfere with drug absorption

          -  Currently participating in another study with an investigational drug or within 28
             days of study entry

          -  History or other evidence of severe illness or any other conditions that would make
             the subject, in the opinion of the investigator, unsuitable for the study (such as
             poorly controlled psychiatric disease or coronary artery disease)

          -  Regular and excessive use of alcohol within the 2 years prior to study entry defined
             as alcohol intake > 14 drinks per week in a man or > 7 drinks per week in a woman.
             Approximately 10 g of alcohol equals one "drink" unit. One unit equals 1 ounce of
             distilled spirits, one 12-ounce beer, or one 4-ounce glass of wine

          -  History or presence of any of the following:

               1. Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) > 2.0 × the
                  upper limit of normal (ULN) at screening. (Subjects with an isolated AST
                  elevation of any magnitude, or a ratio of AST:ALT > 1.5 interviewed regarding use
                  of alcohol, have levels repeated and participation in the study should be
                  discussed with the medical monitor.)
