Eligibility

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 ß-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.

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.

• Mean QTc formula (QTcF) interval > 450 msec;

• A myocardial infarction within 12 months of study entry;

• A history of coronary artery disease (CAD), e.g., angina Canadian Class II-IV. A stress imaging study should be performed for any subject whose cardiac status is uncertain. If abnormal, an angiography should be completed to define whether or not CAD is present.

• An electrocardiogram (ECG) recorded at screening showing evidence of cardiac ischemia (ST depression of = 2 mm, measured from isoelectric line to ST segment). A stress imaging study should be performed for any subject whose cardiac status is uncertain. If abnormal, an angiography should be completed to define whether or not CAD is present.

• Congestive Heart Failure (CHF) that meets the New York Heart Association (NYHA) Class II to IV definitions (see Appendix F) and/or ejection fraction < 40% by multi gated acquisition (MUGA) scan or < 50% by echocardiogram and/or magnetic resonance imaging (MRI);

• A known history of sustained ventricular tachycardia (VT), ventricular fibrillation (VF), torsades de pointes, or cardiac arrest unless currently addressed with an automatic implantable cardioverter defibrillator (AICD);

• Hypertrophic cardiomegaly or restrictive cardiomyopathy from prior treatment or other causes (if in doubt, see ejection fraction criteria above);

• Uncontrolled hypertension, i.e., blood pressure (BP) of = 160/95; or

• Any cardiac arrhythmia requiring anti-arrhythmic medication.

19. Subjects who are pregnant or breast-feeding.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Area Under the Plasma Concentration Time-curve From Time 0 to the Time of the Last Quantifiable Concentration (AUC0-t)of Romidepsin	AUC0-t: area under the plasma concentration time-curve from Time 0 to the time of the last quantifiable concentration (Ct), calculated by linear trapezoidal method when concentrations are increasing and the logarithmic trapezoidal method when concentrations are decreasing.	Days 1 and 8; at 0 (pre-dose), 1, 2, 3, and 4 hours (end of infusion) and at 4.25, 4.5, 5, 6, 8, 10, 12, 24 and 48 hours after the initiation of IV infusion.
Primary	Area Under the Plasma Concentration Time-curve From Time 0 to 24-hour (AUC0-24) for Romidepsin	Individual and mean romidepsin plasma concentrations by treatment and scheduled time data were collected. AUC0-24: area under the plasma concentration time-curve from Time 0 to 24 hours, calculated by linear trapezoidal method when concentrations are increasing and the logarithmic trapezoidal method when concentrations are decreasing.	Day 1 and Day 8; at 0 (predose), 1, 2, 3, and 4 hours (end of infusion) and at 4.25, 4.5, 5, 6, 8, 10, 12, 24 and 48 hours after the initiation of IV infusion.
Primary	Area Under the Plasma Concentration Time-curve From Time Zero Extrapolated to Infinity (AUC0-8).	AUC0-8: area under the plasma concentration time-curve from Time 0 extrapolated to infinity, calculated as [AUCt + Ct/?z]. ?z is the apparent terminal rate constant. No AUC extrapolation was performed with unreliable ?z. If the percentage of AUC extrapolated is = 25%, AUC0-8 will not be reported.	Days 1 and 8; at 0 (predose), 1, 2, 3, and 4 hours (end of infusion) and at 4.25, 4.5, 5, 6, 8, 10, 12, 24 and 48 hours after the initiation of IV infusion.
Primary	Maximum Observed Plasma Concentration (Cmax)of Romidepsin	Maximum observed plasma concentration (Cmax)was obtained directly from the observed concentration versus time data.	Days 1 and 8; at 0 (predose), 1, 2, 3, and 4 hours (end of infusion) and at 4.25, 4.5, 5, 6, 8, 10, 12, 24 and 48 hours after the initiation of IV infusion.
Primary	Time to Maximum Observed Plasma Concentration (Tmax)	Time to maximum observed plasma concentration (Tmax) was obtained directly from the observed concentration versus time data.	Days 1 and 8; at 0 (predose), 1, 2, 3, and 4 hours (end of infusion) and at 4.25, 4.5, 5, 6, 8, 10, 12, 24 and 48 hours after the initiation of IV infusion.
Primary	Estimate of the Terminal Elimination Half-life in Plasma (t1/2)	The terminal elimination half-life (t1/2) in plasma, was calculated as [(ln 2)/?z]. This was only calculated when a reliable estimate for ?z could be obtained.	Days 1 and 8; at 0 (predose), 1, 2, 3, and 4 hours (end of infusion) and at 4.25, 4.5, 5, 6, 8, 10, 12, 24 and 48 hours after the initiation of IV infusion.
Primary	Clearance (CL): Apparent Total Plasma Clearance.	The apparent total plasma clearance (CL) was calculated as [Dose/AUC0-8] for Romidepsin alone and co-administered with rifampin plasma concentrations.	Days 1 and 8; at 0 (predose), 1, 2, 3, and 4 hours (end of infusion) and at 4.25, 4.5, 5, 6, 8, 10, 12, 24 and 48 hours after the initiation of IV infusion.
Primary	Apparent Total Volume of Distribution (Vz).	Apparent total volume of distribution (Vz) was calculated as [(CL)/?z] for Romidepsin and co-administered with Rifampin.	Days 1 and 8; at 0 (predose), 1, 2, 3, and 4 hours (end of infusion) and at 4.25, 4.5, 5, 6, 8, 10, 12, 24 and 48 hours after the initiation of IV infusion.
Secondary	Summary of Participants With Treatment Emergent Adverse Events (TEAEs)	AEs were considered related if assessed by the Investigator as possibly, probably or definitely related to study drug. Serious AEs (SAEs) are those that resulted in death, were life-threatening, required or prolonged inpatient hospitalization, resulted in persistent or significant disability/incapacity, congenital anomaly, or resulted in an important medical event that may have jeopardized the patient or required medical or surgical intervention to prevent one of the outcomes listed above.	Day 1 up to Day 36 (28 days after the last treatment)
