Active clinical trials for "Neoplasms, Plasma Cell"

This study will evaluate the safety and the efficacy of the association of Melphalan/ Prednisone/Thalidomide/Defibrotide (MPTD) as salvage treatment in advanced and refractory myeloma patients. This association might further increase the response rate achieved by oral MPT regimen

This is a phase I/II study of perifosine in combination with bortezomib-with or without dexamethasone-for patients with relapsed or refractory multiple myeloma previously treated with bortezomib. The current protocol will enroll patients with relapsed or refractory multiple myeloma who have been previously treated with bortezomib. The patients will be treated with perifosine, 50 mg or 100 mg qhs, in combination with bortezomib to determine if there is any preliminary evidence that the addition of perifosine improves the outcome for these patients. Previous treatment with perifosine will be allowed in this study. Patients progressing on treatment with perifosine and bortezomib will receive dexamethasone 20 mg on days 1, 2, 4, 5, 8, 9, 11, 12, 15, 16, 18, and 19 of each 21-day cycle in addition to bortezomib and perifosine.

The present study was designed in an attempt to prospectively evaluate in a randomized fashion whether further cytotoxic dose intensification, as delivered with two sequential autologous stem-cell transplantations, improved the outcome of younger patients with newly diagnosed multiple myeloma in comparison with a single autologous transplantation.

The purpose of this study is to determine how well newly diagnosed multiple myeloma patients respond to an experimental regimen of Vincristine, DOXIL (doxorubicin HCl liposome injection) and Dexamethasone (VDD) versus the standard treatment of Vincristine, Doxorubicin and Dexamethasone (VAD).

PRIMARY STUDY OBJECTIVES To evaluate the efficacy of the combination of bortezomib, dexamethasone, with and without DOXIL, followed by high-dose cyclophosphamide as a therapy for two different subsets of multiple myeloma patients: Patients post first line therapy Patients with relapsed/refractory disease who are bortezomib-naïve To evaluate the safety of the combination of bortezomib and dexamethasone, with and without DOXIL, followed by high-dose cyclophosphamide as therapy for patients with multiple myeloma. SECONDARY STUDY OBJECTIVES To evaluate the role of the combination of bortezomib dexamethasone, with and without DOXIL, followed by high-dose cyclophosphamide on the ability to collect > 10 x 106 CD34+ cells/kg in < 7 collections (for both subsets of multiple myeloma patients). To evaluate the survival of patients who receive the combination of bortezomib dexamethasone, with and without DOXIL, followed by high-dose cyclophosphamide (for both subsets of patients).

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with autologous peripheral stem cell transplantation and immunotherapy may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. Biological therapies use different ways to stimulate the immune system and stop cancer cells from growing. PURPOSE: Randomized phase I/II trial to study the effectiveness of combining chemotherapy with peripheral stem cell transplantation followed by immunotherapy in treating patients who have multiple myeloma.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy consisting of busulfan and cyclophosphamide followed by bone marrow transplantation in treating patients who have acute or chronic leukemia or myelodysplastic syndrome.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase I trial to study the effectiveness of pyroxamide in treating patients who have advanced cancer.

RATIONALE: Monoclonal antibodies, such as bevacizumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or deliver cancer-killing substances to them. Thalidomide may stop the growth of cancer cells by stopping blood flow to the tumor. It is not yet known whether bevacizumab works better with or without thalidomide for multiple myeloma. PURPOSE: This randomized phase II trial is to see if bevacizumab works better with or without thalidomide in treating patients who have relapsed or refractory multiple myeloma.
