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.
This study has been designed to evaluate whether "anti-angiogenesis" therapy with thalidomide and whether additional chemotherapy after transplant will be beneficial. Another objective is to find out what kinds of side effects occur with this combination of treatment and how often they occur.
The purpose of this study is to determine if vaccination with autologous idiotype- or tumor lysate-pulsed dendritic cells induces the generation of anti-idiotypic and anti-tumor immunologic responses.
The purpose of this study is to assess the toxicity of PS-341 combined with one of four doses of thalidomide in patients with refractory multiple myeloma, and to find the most appropriate doses of PS-341 and thalidomide in the combination.
The purpose of this research is to study how helpful the combination of thalidomide and Pamidronate is in controlling multiple myeloma and to study any side effects that may be experienced.
Bortezomib may stop the growth of cancer cells by blocking the enzymes necessary for their growth. Drugs used in chemotherapy, such as flavopiridol, work in different ways to stop cancer cells from dividing so they stop growing or die. Bortezomib may increase the effectiveness of flavopiridol by making cancer cells more sensitive to the drug. Giving bortezomib together with flavopiridol may kill more cancer cells. This phase I trial is studying the side effects and best dose of bortezomib and flavopiridol in treating patients with recurrent or refractory indolent B-cell neoplasms.
RATIONALE: Understanding the emotional needs of spouses or others who are living with and caring for patients who have undergone stem cell transplantation may help improve the quality of life of both the caregivers and the patients. PURPOSE: This clinical trial is studying the emotional needs of caregivers of patients who have undergone stem cell transplant.
RATIONALE: Donor peripheral stem cell transplantation may be able to replace bone marrow and immune cells that were destroyed by chemotherapy. Sometimes the transplanted cells from a donor are rejected by the body's normal cells. Eliminating the T cells from the donor cells before transplanting them and giving cyclosporine may prevent this from happening. PURPOSE: This phase I trial is studying the side effects of T-cell-depleted allogeneic stem cell transplantation after immunoablative induction chemotherapy and reduced-intensity transplantation conditioning (chemotherapy) in treating patients with hematologic malignancies.
The purpose of this study is to characterize the clinical pharmacokinetic and pharmacodynamic profiles of the 2 doses of VELCADE (bortezomib) for Injection. Patients who volunteer to participate in the pharmacogenetic portion of the study, an additional blood sample will be collected before the Cycle 1 Day 1 dose of bortezomib to assess the genotype of drug metabolizing enzymes.
