14. May have up to three biological therapies.
15. Voluntary written informed consent before performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care.
16. Female subject is either post-menopausal or surgically sterilized or willing to use an acceptable method of birth control (i.e., a hormonal contraceptive, intra-uterine device, diaphragm with spermicide, condom with spermicide, or abstinence) for the duration of the study.

Exclusion Criteria:

1. Co-medication that may interfere with study results; e.g. immuno-suppressive agents other than corticosteroids.
2. Greater than three prior recurrences.
3. Enzyme-inducing anti-epileptic drugs (EIAEDs) of the CYP-450 such as phenytoin, carbamazepine, phenobarbital.
4. Patients receiving concurrent investigational drugs.
5. Evidence of central nervous system (CNS) hemorrhage on baseline MRI or CT scan (except for grade 1 hemorrhage that has been stable for at least 3 months).
6. History of stroke within six months.
7. Requires therapeutic anti-coagulation.
8. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection requiring IV antibiotics and psychiatric illness/social situations that would limit compliance with study requirements, or disorders associated with significant immunocompromised state.
9. Patient has a calculated or measured creatinine clearance of < 20 mL/minute within 14 days prior to treatment initiation.
