Active clinical trials for "Neoplasms, Plasma Cell"

The purpose of this Phase 2 randomized study is to evaluate the efficacy and safety of treatment with a regimen of VELCADE, dexamethasone, and thalidomide (VDT) or VELCADE, dexamethasone, thalidomide, and cyclophosphamide (VDTC) in subjects with newly diagnosed symptomatic multiple myeloma who have received no prior treatment and are candidates to receive high-dose therapy and autologous bone marrow/stem cell transplantation.

RATIONALE: Giving chemotherapy, such as cyclophosphamide and busulfan, and total-body irradiation before a donor stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells from bone marrow or umbilical cord blood may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving methotrexate and cyclosporine after transplant may stop this from happening. PURPOSE: This phase II trial is studying how well a donor stem cell transplant works in treating patients with previously treated lymphoma, multiple myeloma, or chronic lymphocytic leukemia.

The purpose of this study is to determine the safety and the maximum tolerated dose (MTD) of GRN163L when administered to patients with refractory or relapsed multiple myeloma.

The purpose of this phase II study is to assess the toxicity and efficacy of sequentially administered high dose chemotherapy followed by autologous stem cell rescue in the treatment of multiple myeloma. Prior studies have shown that dose-intensified melphalan can produce higher response rates and complete remission in some patients. Over the past several years, multiple phase II studies utilizing high dose chemotherapy or high dose chemo-radiotherapy with autologous marrow or peripheral blood stem cell rescue have demonstrated improved response rates and survival rates compared to historical controls. Recently a prospective randomized trial has demonstrated improved response rates, response duration and overall survival utilizing high dose therapy with autologous bone marrow support compared to standard chemotherapy. The primary cause of failure is relapse and it is unclear how many, if any, patients are cured by this approach. Based on observations of efficacy in Hodgkin's Disease, Non-Hodgkin's Lymphoma, and breast cancer, an approach utilizing sequential high dose chemotherapy in multiple myeloma was developed. This protocol tests the sequential regimen in multiple myeloma patients who have responded to a standard dose chemotherapy regimen prior to enrollment.

The purpose of this study is to compare bortezomib, dexamethasone and cyclophosphamide to bortezomib and dexamethasone alone for primary refractory or relapsed multiple myeloma.

The purpose of this study is to compare the effects, good and bad, of two ways to treat patients with standard-risk symptomatic multiple myeloma. Patients with standard-risk myeloma have myeloma with specific features: levels of 2 blood tests have to be in a specific range and there can be no myeloma tumors found outside of the bones or bone marrow, the areas where myeloma is usually discovered. In past clinical studies, patients with standard-risk myeloma have done well with intensive therapy in the form of stem cell transplant. But multiple myeloma is not curable and, although it may respond to standard treatments including stem cell transplant, myeloma always recurs.

RATIONALE: Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as doxorubicin and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) together with bortezomib may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving bortezomib together with doxorubicin and dexamethasone works in treating patients with multiple myeloma that has relapsed or not responded to treatment. PATIENT POPULATION: Patients with relapsed or refractory multiple myeloma requiring therapy will be invited to participate in this study. Eligible patients will be >18 years old and able to give fully informed consent. Patients must have a Performance Score (PS) of 0-3 (ECOG), measurable serum and/or urine paraprotein, or serum free light chain, bilirubin value of less than one and a half times the upper limit of normal with ALT/AST values less than two and a half times the upper limit of normal. Patients with non-secretory multiple myeloma are excluded from this study.

This Phase I/IIa clinical study is to test safety and anti-tumor activity of BT062 to define the best dose in treating patients with relapsed or refractory multiple myeloma with multiple doses of BT062.

The investigators major aim is to determine whether there is a difference in the retention of zoledronic acid in multiple myeloma patients, compared to patients with breast cancer metastasis to bone. In addition the investigators wish to analyze if the retention of zoledronic acid is correlated to the extent of bone resorption/formation, and if there is a tendency to changes in retention with sequential treatment.

RATIONALE: Bortezomib and thalidomide may stop the growth of multiple myeloma by blocking blood flow to the cancer. Bortezomib may also stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving bortezomib together with thalidomide and dexamethasone may kill any cancer cells that remain after high-dose melphalan and stem cell transplant in patients with multiple myeloma. PURPOSE: This phase II trial is studying the side effects of giving bortezomib together with thalidomide and dexamethasone after melphalan and stem cell transplant and to see how well it works in treating patients with stage I-III multiple myeloma.
