Filter by:RATIONALE: When irradiated lymphocytes from a donor are infused into the patient they may help the patient's immune system kill cancer cells. Monoclonal antibodies, such as rituximab, 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 carry cancer-killing substances to them. Giving irradiated donor lymphocytes together with rituximab may kill more cancer cells. PURPOSE: This clinical trial is studying the side effects and how well giving irradiated donor lymphocytes together with rituximab works in treating patients with relapsed or refractory lymphoproliferative disease.
Multiple myeloma is a disease of B-lymphocytes producing malignant plasma cells. Malignant plasma cells induce osteolytic lesions, which is characteristic for progression of multiple myeloma. It is the aim of this study to investigate whether zoledronic acid has an influence on the progression of multiple myeloma.
Velcade (bortezomib, PS-341) has recently been approved by the Food and Drug Administration (FDA) for the treatment of multiple myeloma for patients who have received at least one prior therapy. Velcade is a unique compound developed by scientists at Millennium Pharmaceuticals, Inc. Velcade enters cells and affects the way they divide. Cancer cells are particularly sensitive. Velcade interferes with the enzyme "proteasome" which is responsible for allowing cells to divide. When cancer cells cannot divide, they die. Velcade falls into the class of drugs known as "proteasome inhibitors."
RATIONALE: Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Biological therapies, such as thalidomide, may stimulate the immune system in different ways and stop cancer cells from growing. It may also stop the growth of cancer by blocking blood flow to the cancer. Drugs used in chemotherapy, such as dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving bortezomib together with thalidomide and dexamethasone may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving bortezomib together with thalidomide and dexamethasone works in treating patients with relapsed or refractory multiple myeloma.
The purpose of this study is to find out if patients with high risk disease because of age or kidney status can be treated more safely with a drug called Busulfex® followed by autologous transplant compared to treatment with the standard drug called melphalan, which has been shown to be quite difficult to tolerate in patients with poor kidney function and patients over the age of 65 when given in high doses.
The purposes of this study are: - To determine the maximum tolerated dose (MTD) of SAHA administered every 12 hours for 14 consecutive days followed by 7 days of rest during the first two cycles (i.e., first 6 weeks) in patients with advanced multiple myeloma; - To assess the safety and overall response rate to SAHA in patients with advanced multiple myeloma.
STR (Skeletal Targeted Radiotherapy, 166Ho-DOTMP) is an investigational radiopharmaceutical that delivers radiation directly to cancer cells in the bone and bone marrow. Conventional methods of delivering radiation therapy, such as total body irradiation, expose non-target tissues to radiation and cause serious side effects. In contrast, STR's targeted approach to delivering radiotherapy concentrates the radiation where it is needed, and minimizes exposure of normal tissues. STR is composed of a bone-targeting molecule, DOTMP, in a stable complex with the radionuclide holmium-166. When injected into a patient's bloodstream, STR rapidly binds to bone mineral, delivering a brief, intense dose of radiation to destroy cancer cells in the bone and marrow. The high-energy and long path-length of holmium-166 beta particles provide optimal penetration and uniform irradiation of disease sites in the marrow and bone. STR that does not bind to bone is rapidly eliminated through the urinary tract. STR treatment is followed by autologous stem cell transplantation. The short half-life of holmium-166 allows treatment on an out-patient basis, and minimizes the time required between STR administration and transplantation. The phase III study of STR is a multi-center, randomized, controlled study, designed to evaluate the safety and efficacy of STR in patients with primary refractory multiple myeloma. These are patients who have failed to achieve at least a partial response to conventional therapy and have been undergoing treatment for less than 18 months. The trial is expected to enroll approximately 240 evaluable patients, half on the experimental arm and half on the control arm. Patients on the experimental arm will receive STR at a dose of 750 mCi/m2 plus the chemotherapy drug melphalan at 200 mg/m2, followed by autologous stem cell transplantation. Patients on the control arm will receive melphalan only, followed by transplantation. Patients on both study arms will be evaluated for response to treatment six months after transplantation, using an immunofixation assay to detect myeloma protein in patient samples. Analysis of patient samples will be conducted at a central laboratory, and blinded results will be reviewed by an independent panel of experts. The study's primary endpoint is complete response, as determined by the complete disappearance of myeloma protein at six months post-transplant.
RATIONALE: Antibiotics such as amoxicillin, ciprofloxacin, and moxifloxacin may be effective in preventing or controlling fever and neutropenia in patients with cancer. It is not yet known whether moxifloxacin alone is more effective than amoxicillin combined with ciprofloxacin in treating neutropenia and fever. PURPOSE: This randomized clinical trial is studying how well moxifloxacin works and compares it to ciprofloxacin together with amoxicillin in treating neutropenia and fever in patients with cancer.
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of plasma cells, either by killing the cells or by stopping them from dividing. Having a peripheral stem cell transplant to replace the blood-forming cells destroyed by chemotherapy, allows higher dose of chemotherapy to be given so that more plasma cells are killed. Giving a chemoprotective drug such as amifostine may protect kidney cells from the side effects of chemotherapy. PURPOSE: This phase I trial is studying the side effects and best dose of melphalan given together with amifostine in treating patients who are undergoing peripheral stem cell transplant for primary systemic amyloidosis.
Multiple myeloma is a disease that resides primarily in the bone and has shown to be sensitive to radiation. Administration of a radiotherapy agent that targets the bone, such as Holmium-166-DOTMP, in conjunction with melphalan and an autologous stem cell transplant, may improve the patient's chance of responding to treatment. The purpose of this study is to determine the amount of Holmium-166-DOTMP that localizes in the bone and in normal organs, and to evaluate the safety and efficacy of Holmium-166-DOTMP in the treatment of patients with multiple myeloma.
