9. Must use acceptable form of birth control while on study.

10. Willing to provide tissue and blood samples.

11. Ability to understand and willingness to sign a written informed consent document.

Exclusion Criteria:

1. Chemotherapy, radiotherapy, investigational therapy, or surgery less than 3 weeks prior to trial registration

2. Prior treatment with epigenetic therapy (such as entinostat, panobinostat, vorinostat, romidepsin, 5-azacitidine, or decitabine)

8. Known history or evidence of brain metastases.

9. Conditions, including alcohol or drug dependence, intercurrent illness, or lack of sufficient peripheral venous access, that would affect the patient's ability to comply with study visits and procedures.

10. Are pregnant or breastfeeding.

11. Infection with HIV or hepatitis B or C.

12. Patients on immunosuppressive agents.

13. Requiring concurrent administration of valproic acid.

14. Patients with diverticulitis, intra-abdominal abscess, or GI obstruction

15. Any contraindication to oral agents.

16. Another active malignancy ≤ 3 years prior to registration with the exception of non-melanotic skin cancer or carcinoma-in-situ of any type.

17. Unwilling or unable to follow the study schedule for any reason.

18. Evidence of ascites on imaging.
