Oncaspar, Doxil, Decadron Regimen for Multiple Myeloma

This is an exploratory study to study the efficacy of combination regimen of Oncaspar/Doxil/Decadron (ODD) in patients with refractory lymphoid malignancies. Patients with any form of lymphoid malignancy will be eligible: acute lymphoblastic leukemia, chronic lymphocytic leukemia, non-Hodgkin's lymphoma, Hodgkin's lymphoma, multiple myeloma and plasma cell leukemia. Patients must have failed standard regimens for their cancers and could have had unlimited number of prior regimens. Patients will be staged appropriately for their disease with clinical examination, laboratory tests, and imaging studies. Both Oncaspar and Doxil will be given on day 1 and 15. Patients will be clinically evaluated prior to each cycle and will have disease assessments every 2 cycles. Responding patients will continue therapy until disease progression or excessive toxicity. Responders who are candidates for allogenic stem cell transplantation could go to conditioning chemotherapy and stem cell transplant after 4 cycles of ODD.
