Eligibility criteria:

        Inclusion Criteria:

          1. Males and females 18 years of age or older at the time of signing the informed consent
             document.

          2. Understand and voluntarily sign an informed consent document prior to any study
             related assessments/procedures are conducted.

          3. Able to adhere to the study visit schedule and other protocol requirements.

          4. Must have diagnosis of advanced malignancy and must have failed other available
             therapies considered standard of care for their disease.

          5. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.

          6. Negative urine or serum pregnancy test on females of childbearing potential; and

          7. All females of childbearing potential must use an effective barrier method of
             contraception (either an intrauterine contraceptive device [IUCD] or double barrier
             method using condoms or a diaphragm plus spermicide) during the treatment period and
             for at least 1 month thereafter. Male subjects should use a barrier method of
             contraception during the treatment period and for at least 3 months thereafter. Female
             subjects should avoid the use of estrogen-containing contraceptives, since romidepsin
             may reduce the effectiveness of estrogen-containing contraceptives. An in vitro
             binding assay determined that romidepsin competes with β-estradiol for binding to
             estrogen receptors.

        Exclusion Criteria:

          1. Any significant medical condition or psychiatric illness that would prevent the
             subject from participating in the study.

          2. Any condition, including the presence of laboratory abnormalities, which places the
             subject at unacceptable risk if he/she were to participate in the study.

          3. Subjects with significant gastrointestinal disease that may impair drug absorption,
             such as subjects with a history of Cohn's disease, colectomy, gastrectomy, celiac
             disease, or other diseases with known malabsorption.

          4. Serum potassium < 3.8 mmol/L or serum magnesium < 0.85 mmol/L (magnesium converts to
             2.1 mg/dl or 1.7 mEq/L) (electrolyte abnormalities can be corrected with
             supplementation to meet inclusion criteria).

          5. Concomitant use of drugs that may cause a significant prolongation of the corrected
             measurement of the time between the start of the cardiac Q wave and the end of the T
             wave (QTc).

          6. Concomitant use of Cytochrome P 450 3A4 (CYP3A4) strong inhibitors within 1 week of
             trial medications.

          7. Concomitant use of CYP3A4 strong inducers within 2 weeks of trial medications.

          8. Concomitant use of therapeutic warfarin due to a potential drug interaction. Use of a
             low dose of warfarin or another anticoagulant to maintain patency of venous access
             port and cannulas is permitted.
