• The patient, if a main, is surgically sterile, or if capable of producing offspring, is currently using an approved method of birth control, and agrees to continued use of this method for the duration of the study (and for 60 days after taking the last dose of CEP-701 because of the possible effects on spermatogenesis).
• The patient must be willing and able to comply with study procedures and restrictions and willing to return to the clinic for the follow-up evaluation as specified in this protocol.

Exclusion Criteria:

• The patient has received treatment with systemic psoriasis treatments (specifically, retinoids, methotrexate, cyclosporine A, etanercept, efalizumab, other biological agents or other immunomodulators) within 4 weeks, or UV based therapy within 2 weeks, or alefacept within 6 weeks of the planned 1st day of study treatment.
• The patient has received treatment with potent CYP3A4 inhibitors including cyclosporine, clotrimazole, fluconazole, itraconazole, ketoconazole, voriconazole, erythromycin, clarithromycin, and troleandomycin, human immunodeficiency virus (HIV) protease inhibitors, or nefazodone within 1 week (7 days) of the planned 1st day of study treatment.
• The patient is currently receiving warfarin.
• The patient has hypersensitivity to CEP-701 or any component of CEP-701.
• The patient has one or more of the following serum chemistry values as determined at the screening visit (visit 1):
• bilirubin levels greater than 2 times the upper limit of normal (ULN)
• ALT or AST levels greater than 2 times the ULN
• serum creatinine levels or more than 2mg/dL
• The patient requires current treatment for HIV with protease inhibitors.
• The patient is taking medication for a clinical diagnosis of gastrointestinal ulceration or has experienced melena or hematoemesis in the previous 3 weeks.
• The patient is a woman who is pregnant or lactating.
