Criteria

Inclusion Criteria

Patients must fulfill all of the following criteria to be eligible for study participation:

• Male or female patients aged ≥ 18 years old

• Has given voluntary written informed consent before any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to their future medical care

• Previously diagnosed with multiple myeloma (MM) based on standard criteria as follows:

• Major criteria:

1. Plasmacytomas on tissue biopsy.

2. Bone marrow plasmacytosis (>30% plasma cells).

3. Monoclonal immunoglobulin spike on serum electrophoresis IgG >3.5 g/dL or IgA >2.0 g/dL; kappa or lambda light chain excretion >1 g/day on 24 hour urine protein electrophoresis

• Minor criteria:

1. Bone marrow plasmacytosis (10 to 30% plasma cells)

2. Monoclonal immunoglobulin present but of lesser magnitude than given under major criteria

3. Lytic bone lesions.

4. Normal IgM <50 mg/dL, IgA <100 mg/dL or IgG <600 mg/dL

Any of the following sets of criteria will confirm the diagnosis of MM:

• Any two of the major criteria

• Major criterion 1 plus minor criterion 2, 3, or 4.

• Major criterion 3 plus minor criterion 1 or 3.

• Minor criteria 1, 2, and 3 or 1, 2, and 4.

• Life-expectancy > 3 months

• All women of childbearing potential must use an effective barrier method of contraception. Male patients should use a barrier method of contraception during the treatment period and for 3 months thereafter

• Patients must meet the following laboratory criteria at Baseline (Day 1 of Cycle 1, before study drug administration):

• Platelet count ≥ 100*10^9/L

• OR if the bone marrow is extensively infiltrated

• Platelet count ≥ 75*10^9/L

• Absolute neutrophil count ≥ 1.0*10^9/L

• Patients must meet the following laboratory criteria at the Screening visit conducted within 14 days of enrollment (Day 1, Cycle 1):

• Serum bilirubin ≤ 2.0*ULN

• Calculated or measured creatinine clearance: ≥30 mL/minute. Patient with a creatinine >10mL/min and <30 mL/min due to significant myelomatous involvement of the kidneys may be enrolled in the study after receipt of approval from the lead investigator and sponsor

• Serum potassium ≥ 3.8 mmol/L

• Serum magnesium >1.8 mg/dL

• Serum phosphorus ≥ lower limit of normal (LLN)

Exclusion Criteria

Patients are ineligible for entry if any of the following criteria are met:

• Chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) or thalidomide, lenalidomide, arsenic trioxide, bortezomib, or glucocorticosteroids within 3 weeks prior to the first dose of romidepsin

• Prior major surgery within 3 weeks prior to the first day of treatment

• Use of any investigational agent within 4 weeks of study entry

• Prior therapy with romidepsin

• Any known cardiac abnormalities such as:

• Congenital long QT syndrome;

• QTc interval ≥ 500 milliseconds;

• Myocardial infarction within 6 months of Day 1. Subjects with a history of myocardial infarction between 6 and 12 months prior to the first day of cycle one who are asymptomatic and have had a negative cardiac risk assessment (treadmill stress test, nuclear medicine stress test, or stress echocardiogram) since the event may participate;

• Other significant electrocardiogram (ECG) abnormalities including 2nd degree atrio-ventricular (AV) block type II, 3rd degree AV block, or bradycardia (ventricular rate less than 50 beats/min);

• Symptomatic coronary artery disease (CAD), e.g., angina Canadian Class II-IV In any patient in whom there is doubt, the patient should have a stress imaging study and, if abnormal, angiography to define whether or not CAD is present;

• An ECG recorded at screening showing evidence of cardiac ischemia (ST depression depression of ≥2 mm, measured from isoelectric line to the ST segment). If in any doubt, the patient should have a stress imaging study and, if abnormal, angiography to define whether or not CAD is present;

• Congestive heart failure (CHF) that meets New York Heart Association (NYHA) Class II to IV definitions and/or ejection fraction <40% by Multi Gated Acquisition Scan (MUGA scan) or <50% by echocardiogram and/or MRI;

• A known history of sustained ventricular tachycardia (VT), ventricular fibrillation (VF), Torsade 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;

• Uncontrolled hypertension, i.e., blood pressure (BP) of ≥160/95; patients who have a history of hypertension controlled by medication must be on a stable dose (for at least one month) and meet all other inclusion criteria; or
