1. Understand and voluntarily sign an informed consent document prior to any study related assessments/procedures being conducted.
2. Male and female subjects ≥18 years of age at the time of signing the informed consent document.
3. Able to adhere to the study visit schedule and other protocol requirements.
4. Diagnosed with Behçet’s disease meeting the International Study Group (ISG) criteria.
5. Oral ulcers that occurred at least 3 times in the previous 12-month period, including oral ulcers at the Screening Visit.
6. Subjects must have at least 2 oral ulcers at Visit 1 (Screening Visit), and:
a) at least 2 oral ulcers at Visit 2 (day of randomization), when Visit 2 occurs at least 14 days after Visit 1,
OR
b) at least 3 oral ulcers at Visit 2 (day of randomization), when Visit 2 occurs at any time between 1 day and 42 days after Visit 1.
7. Have prior treatment with at least 1 non-biologic BD therapy, such as, but not limited to, topical corticosteroids, or systemic treatment.
8. Candidate for systemic therapy, for the treatment of oral ulcers.
a. A candidate for systemic therapy is a subject, judged by the study Investigator, as someone whose mucocutaneous ulcers are considered inappropriate for topical therapy based on the severity of disease and extent of the affected area, or whose oral ulcers cannot be adequately controlled by topical therapy.
9. Laboratory Measures: Must meet the following laboratory measures:
• Hemoglobin > 9 g/dL
• White blood cell (WBC) count ≥ 3000 /microL (≥ 3.0 X 109/L) and ≤14,000/microL (≤14 X 109/L)
• Platelet count ≥ 100,000 /microL (≥ 100 X 109/L)
• Serum creatinine ≤ 1.5 mg/dL (≤ 132.6 μmol/L)
• Total bilirubin ≤ 2.0 mg/dL
• Aspartate transaminase (AST [serum glutamic oxaloacetic transaminase, SGOT]) and alanine transaminase (ALT [serum glutamate pyruvic transaminase, SGPT]) <1.5 X ULN. Subjects who fail screening due to ≥ 1.5 X ULN AST/SGOT and/or ALT/SGPT will be allowed to repeat AST/SGOT and/or ALT/SGPT tests within the screening period. Repeat test results should be ≤ ULN (within reference range) to be eligible.
Laboratory tests will be allowed to be repeated 1 time, if in the Investigator’s clinical judgment, there is a reasonable possibility of the repeat tests not meeting the exclusion values, and with concurrence from the Medical Monitor.
10. Contraception Requirements:
All FCBP must use one of the approved contraceptive options as described below while taking apremilast and for at least 28 days after administration of the last dose of the apremilast.
At the time of study entry, and at any time during the study when a FCBP’s contraceptive measures or ability to become pregnant changes, the Investigator will educate the subject regarding contraception options and the correct and consistent use of effective contraceptive methods in order to successfully prevent pregnancy.
All FCBP must have a negative pregnancy test at Visits 1 and 2. All FCBP subjects who engage in activity in which conception is possible must use one of the approved contraceptive options described below:
Option 1: Any one of the following highly effective methods: hormonal contraception (oral, injection, implant, transdermal patch, vaginal ring); intrauterine device (IUD); tubal ligation; or partner’s vasectomy;
OR
Option 2: Male or female condom (latex condom or non latex condom NOT made out of natural [animal] membrane [for example, polyurethane]); PLUS one additional barrier method: (a) diaphragm with spermicide; (b) cervical cap with spermicide; or (c) contraceptive sponge with spermicide.
Male subjects (including those who have had a vasectomy) who engage in activity in which conception is possible must use barrier contraception (latex or non-latex condoms NOT made out of natural [animal] membrane [for example, polyurethane]) while on IP and for at least 28 days after the last dose of IP.
