Phase I Study of Romidepsin, Gemcitabine, Oxaliplatin, and Dexamethasone in Patients With Relapsed/Refractory Aggressive Lymphomas

Inclusion Criteria:

Able to understand and voluntarily sign an informed consent form
Age ≥ 18 at time of informed consent

Diagnosis of one of the following:

relapsed/refractory peripheral T-cell lymphoma of any subtype including mycosis fungoides and Sézary syndrome of advanced stage (IIB-IVB)

**for the expansion cohort:patients must have biopsy-proven T-cell lymphoma and measurable disease.

relapsed/refractory DLBCL (up to 6 DLBCL patients are allowed in the dose-escalation portion of the study)
relapsed/refractory HL

Note: extracorporeal photopheresis is NOT considered a systemic therapy for this study.

Transplant eligible (as determined by referring physician) patients who have failed one prior salvage therapy or transplant ineligible (as determined by referring physician) patients who have failed one prior therapy
ECOG performance status of ≤ 2

Laboratory test results within the following ranges:

Absolute neutrophil count ≥ 1500/mm³
Platelet count ≥ 100,000/mm³
Total bilirubin ≤ 1.5 x ULN
AST (SGOT) and ALT (SGPT) ≤ 3 x ULN
Creatinine < 2 mg/dL
Potassium ≥ 3.3 mmol/L or at/above the lower limit of normal for the performing laboratory
Magnesium ≥ 1.4 mg/dL or at/above the lower limit of normal for the performing laboratory.
Negative serum pregnancy test for women of childbearing potential
Washout time of at least 4 weeks for prior biological, chemotherapeutic, or radiotherapy

Exclusion Criteria:

Any serious medical condition, laboratory abnormality, or psychiatric illness that would - in the opinion of the investigator - prevent the subject from signing the informed consent form
Pregnant or lactating women
Any medical condition or laboratory abnormalities, which - in the opinion of the investigator - places the subject at unacceptable risk, or confounds the ability to interpret data if he/she were to participate in the study
Positive CSF cytology during staging, symptomatic leptomeningeal involvement, or parenchymal involvement of brain or spinal cord
Prior allogeneic hematopoietic cell transplant
Prior solid organ transplant
Cirrhotic liver disease from any cause
Known HIV infection

Impaired cardiac function or clinically significant cardiac disease including any of the following:

Congenital long QT syndrome
Screening ECG with QTc interval ≥ 500 milliseconds
Myocardial infarction (MI) or unstable angina ≤ 6 months of C1D1; however, subjects with a history of MI between 6 and 12 months who are asymptomatic and have had a negative cardiac risk assessment (treadmill stress test, nuclear medicine stress test, or stress echocardiogram) since the event would be eligible
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 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
Other significant ECG abnormalities including 2nd degree atrio-ventricular (AV) block type II, 3rd degree AV block, or bradycardia (defined here as ventricular rate < 50 bpm); right bundle-branch block + left anterior hemi-block (bifasicular block)
Congestive heart failure (CHF) that meets New York Heart Association (NYHA) Class II to IV definitions (see Appendix 9) and/or ejection fraction <40% by MUGA scan or <50% by echocardiogram and/or MRI History or presence of sustained ventricular tachycardia (VT), ventricular fibrillation (VF), torsade de pointes, or cardiac arrest
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
Any cardiac arrhythmia requiring an anti-arrhythmic medication, excluding stable (i.e., at least 30 days from screening) doses of beta-blockers
Concomitant use of drugs that may cause significant QT prolongation and/or torsades de pointes that cannot be discontinued or switched to a different medication prior to treatment
Concomitant use of CYP3A4 inhibitors or inducers unless able to stop medication(s) prior to starting study treatment
Patients who are unwilling to stop the use of herbal remedies while receiving study treatment
Unable to accept blood product transfusions
Men whose sexual partners are women of childbearing potential not using a double method of contraception during the study and 3 months after the end of treatment. One of these methods must be a condom
Concurrent malignancy requiring active therapy *Patients with localized prostate cancer having undergone surgery or radiation (field confined to ≤ 30% of marrow-bearing bone) at least 30 days prior to study treatment are eligible
