Official Title: Phase 1 Trial of Siplizumab and Dose-Adjusted EPOCH-Rituximab (DA-EPOCH-R) in T and NK-Cell Lymphomas
Brief Summary:
Studies conducted at the National Cancer Institute suggest that certain chemotherapy drugs may be more effective if given by continuous infusion into the vein rather than by the standard method of rapid intravenous injection. One such combination of six chemotherapy drugs, known as EPOCH-R, has had a high degree of effectiveness in people with certain kinds of cancer. Recent evidence also indicates that the effects of chemotherapy may be improved by combining the treatment with monoclonal antibodies, which are purified proteins that are specially made to attach to foreign substances such as cancer cells. This protocol is specifically for adults with the types of cancer known as T-cell and NK-cell lymphomas, who have never received chemotherapy previously. The additional monoclonal antibody in the study, called siplizumab, has been manufactured to attach to the CD2 protein contained in these types of tumors.
Study volunteers will need to undergo an initial period of evaluation that may take up to 3 weeks and may be done on an outpatient basis. Evaluation may include some or all of the following tests: blood and urine tests, tests of lung and heart function, lumbar punctures to take samples of cerebrospinal fluid, magnetic resonance imaging (MRI) or computerized tomography (CT) scans, full-body positron emission tomography (PET) scans, bone marrow biopsies, and biopsies of suspected tumor areas.
During the study, patients will receive EPOCH-R chemotherapy, which includes the following drugs: etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab. The additional drug, siplizumab, will be given by IV infusion on the first day of treatment over several hours. When the siplizumab IV infusion is complete, the drugs doxorubicin, etoposide, and vincristine will each be given by continuous IV infusion over
