Brief summary

This is a study to test how safe the combination of the drugs Romidepsin and Pralatrexate are in patients with lymphoid malignancies and to determine the dose of the combination of drugs that is safest. If the combination is determined to be safe, the study will continue accrual patients with peripheral T-Cell lymphoma (PTCL).

Detailed description

The non- Hodgkin lymphomas (NHL) represent a heterogeneous group of malignancies. Under the rubric of lymphoma exist some of the fastest growing cancers known to science, (Burkett's lymphoma, lymphoblastic lymphoma/leukemia), as well as some of the most indolent (small lymphocytic lymphoma, follicular lymphoma, and marginal zone lymphoma). This remarkable diversity of biology imposes significant challenges. Researchers are seeking to understand the cell of origin and differentiate what are sometimes subtle differences between the related sub-types of disease; and to identify the best treatments for these subtypes, with the ever-increasing likelihood that new understanding of the molecular pathogenesis of these diseases will result in an increase in new drugs for specific target populations.

Interventions

DRUGPralatrexate

Phase I - Schedule A: Intravenous drug given on days 1 and 8 of each 21 day cycle Schedule B: Intravenous drug given on days 1 and 15 of each 28 day cycle Dose escalation from 10 mg/m2 to 25 mg/m2 Phase II - 25 mg/m2 will be given intravenously once weekly on days 1 and 15 on a 28 day cycle.

DRUGRomidepsin

Phase I - Schedule A: Intravenous drug given on days 1 and 8 of each 21 day cycle Schedule B: Intravenous drug given on days 1 and 15 of each 28 day cycle Dose escalation from 12 mg/m2 to 14 mg/m2. Phase II - 12 mg/m2 will be given intravenously once weekly on days 1 and 15 on a 28 day cycle.

Inclusion criteria

Phase I: Patients must have histologically confirmed relapsed or refractory Non-Hodgkin's lymphoma, Hodgkin's Disease or multiple myeloma (defined by World Health Organization (WHO) criteria). Phase II: Patients must have histologically confirmed relapsed or refractory T-Cell Lymphoma (as defined by WHO criteria). * Must have received first line chemotherapy. No upper limit for the number of prior therapies * Evaluable Disease * Age ≥18 years * Eastern Cooperative Oncology Group (ECOG) performance status ≤2 * Patients must have adequate organ and marrow function as defined in the protocol * Adequate Contraception * Ability to understand and the willingness to sign a written informed consent document * Inclusion Criteria for Multiple Myeloma patients specified in the protocol

Exclusion criteria

* Prior Therapy * Exposure to chemotherapy or radiotherapy within 2 weeks (6 weeks for nitrosureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 2 weeks earlier * Systemic steroids that have not been stabilized to the equivalent of ≤10 mg/day prednisone prior to the start of the study drugs * No other investigational agents are allowed * Central nervous system metastases, including lymphomatous meningitis * History of allergic reactions to Pralatrexate or Romidepsin * Uncontrolled intercurrent illness * Pregnant women * Nursing women * Current malignancy or history of a prior malignancy, as outlined in the protocol * Patient known to be Human Immunodeficiency Virus (HIV)-positive * Active Hepatitis A, Hepatitis B, or Hepatitis C infection

Design outcomes

Primary

MeasureTime frameDescription
Maximum Tolerated Dose (MTD) of the Combination of Pralatrexate and Romidepsin in Phase 1Up to 1.5 yearsThe MTD was defined as the dose level at which one-third or fewer patients experienced a dose limiting toxicity. The MTD is determined in clinical trials by testing increasing doses on different groups of people until the highest dose with acceptable side effects is found.
Overall Response Rate (ORR) of Subjects Who Received Combination of Pralatrexate and Romidepsin in Phase 2Up to 3 yearsORR was defined as the number of subjects in a study or treatment group who have a partial response or complete response to the treatment within a certain period of time. A partial response is a decrease in the size of a tumor or in the amount of cancer in the body, and a complete response is the disappearance of all signs of cancer in the body. In a clinical trial, measuring the ORR is one way to see how well a new treatment works.

MeasureTime frameDescription
Overall Response Rate (ORR) of Subjects Who Received Combination of Pralatrexate and Romidepsin in Phase 1Up to 1.5 yearsORR was defined as the number of subjects in a study or treatment group who have a partial response or complete response to the treatment within a certain period of time.

In a clinical trial, measuring the ORR is one way to see how well a new treatment works.
Overall Survival (OS) of Subjects in Phase 2Up to 3 yearsOS was defined as the length of time from either the date of diagnosis or the start of treatment for a disease, such as cancer, that patients diagnosed with the disease are still alive. In a clinical trial, measuring the OS is one way to see how well a new treatment works.
Progression Free Survival (PFS) of Subjects in Phase 2Up to 3 yearsPFS was defined as the length of time during and after the treatment of a disease, such as cancer, that a patient lives with the disease but it does not get worse. In a clinical trial, measuring the PFS is one way to see how well a new treatment works.
