5. Patients must have oral ulcers or genital ulcers that have been resistant to colchicine or topical measures for at least a month.

6. Female subjects who have had a breast cancer screening that is suspicious for malignancy and in whom the possibility of malignancy cannot be reasonably excluded by additional clinical, laboratory, or other diagnostic evaluations.
7. Subjects with a history of cancer in the last 5 years, other than non-melanoma skin cell cancers cured by local resection or carcinoma in situ.

21. Serum ALT or AST > 2 times the ULN
22. Any other laboratory test results that, in the opinion of the investigator, might place a subject at unacceptable risk for participation in the study.
