Filter by:This study has two main aims. The first is to assess whether Dexamethasone can increase the number of patients with who respond to Velcade. The second aim of this study is to see whether treating patients with relapsed multiple myeloma with Velcade and Dexamethasone for a longer period of time extends the time that the myeloma is under control.
The purpose of this study is to determine if denosumab is non-inferior to zoledronic acid (Zometa®) in the treatment of bone metastases (lytic bone lesions from multiple myeloma) in subjects with advanced cancer and multiple myeloma (excluding breast and prostate cancer)
AMP-007 is a Phase 1/2 study for the treatment of advanced, previously treated multiple myeloma. The first phase of the study is designed to determine a safe dose of imexon that can be given to patients with advanced, previously-treated multiple myeloma. The Phase 2 part of the study is designed to provide additional safety data and to gain an understanding of whether imexon can improve the outcome for patients with multiple myeloma
The purpose of this research study is to determine the safest dose of topotecan when given in a high dose before a stem cell transplant; topotecan will be given with melphalan.
Multiple myeloma is a rare form of malignancy in which neoplastic plasma cells accumulate in the bone marrow. Most malignant plasma cells continue to produce immunoglobulin. The activity of multiple myeloma can therefore usually be monitored easily by serial measurement of the serum paraprotein levels. Except for a few patients who receive a donor bone marrow transplant, multiple myeloma remains incurable despite intensive chemotherapy. Its course is typically marked by periods of active disease alternating with increasingly shorter remissions. Interferons are substances produced in human cells in response to a variety of stimuli, such as viral infection. When given to myeloma patients as part of maintenance treatment , interferon-alpha 2 b (INTRONA) has been shown to be of value in prolonging the periods of remission. Until now, INTRONA could only be given as injections under the skin, three times a week. Some patients experience flu-like symptoms with each injection, particularly early on during maintenance therapy. This, as well as the chronic fatigue and even depression that INTRONA can induce may considerably reduce the quality of life of myeloma patients on interferon, so much so that sometimes this useful adjunct to chemotherapy for myeloma has to be stopped. Recently, a new preparation of interferon namely pegylated interferon (PEG Intron) has become available. It has the advantage of being broken down much more slowly by the body and therefore only needs to be given once a week. This minimises the swings in blood interferon levels that may be responsible for some of the interferon side effects. The safety and superior tolerability of PEG Intron has already been demonstrated in patients with hepatitis C for which it now carries a licence, but not in myeloma patients. Here, we propose to study whether the quality of life and side effect profile of myeloma patients on PEG Intron is better compared to that of Intron®A. In the main study, consenting eligible myeloma patients who are well and have been established on INTRONA maintenance therapy for at least six weeks will be randomly allocated to receive PEG Intron for three months followed by INTRONA for 3 months, or to continue with INTRONA for 3 months followed by PEG Intron for 3 months. All patients will be monitored regularly for any side effects and will be asked to fill in a quality of life questionnaire at the beginning (i.e. before receiving the first randomised treatment) and at the end of each study period (i.e. at 3 and 6 months). Initially, we are aiming at enrolling 60 patients into this part of the study. In a smaller sub-study involving only 14 patients initially, we are proposing to investigate whether myeloma patients who need to be taken off Intron®A because of its side effects can tolerate PEG Intron more easily. Should their tolerance of PEG Intron also be poor we would stop the interferon maintenance therapy altogether. However, should PEG Intron be found to be acceptable to them, we intend to switch these patients back to the standard treatment at the end of six weeks treatment with PEG Intron to assess whether they have become more tolerant of Intron®A in the intervening period. Patients will again be monitored carefully for any side effects and will be asked to fill in three quality of life questionnaires (at 0, 6 and 12 weeks).
This study evaluates the safety of plerixafor and other outcomes that are purely exploratory in nature. One other pre-specified outcome is to evaluate an interval of 10-11 hours between dosing with plerixafor and the beginning of apheresis to determine if there will be at least a 2-fold increase in circulating CD34+ cells. Data from this protocol will assist in the determination of the dosing schedule for future studies.
This study evaluates the safety and efficacy of plerixafor given in addition to granulocyte-colony stimulating factor (G-CSF) for collection of peripheral blood stem cells (PBSCs) for autologous transplantation in patients with non-Hodgkin's lymphoma (NHL) and multiple myeloma (MM). Efficacy outcomes include evaluation of fold increase in circulating CD34+ cells from just before the first plerixafor injection to 10-11 hours post plerixafor (just before apheresis) and assessment of successful polymorphonuclear leukocyte (PMN) engraftment after transplantation. Data from this protocol will assist in the determination of the dosing schedule for future studies.
Patients with multiple myeloma (MM) and non-Hodgkin's lymphoma (NHL) will be mobilized with chemotherapy and G-CSF plus plerixafor (AMD3100). The purpose of this protocol is to determine if plerixafor given after chemotherapy and G-CSF mobilization regimen is safe, if it can increase the circulating levels of peripheral blood stem cells (PBSCs) by ≥ 2-fold before apheresis, and if transplantation with the apheresis product was successful, as measured by time to engraftment of polymorphonuclear leukocytes (PMNs) and platelets (PLTs).
Multiple Myeloma is a incurable disease. Recently developed targeted therapy gave new hope for the patients with multiple myeloma. Velcade in combination with other agents are currently in trials for the newly diagnosed patient, we designed sequential treatment with VTD and MPT for the patients who are not transplant candidates. This would be expected to result in maximal tumor control, and thus, in maximal survival benefit, equivalent to high dose therapy with autologous transplantation in younger population
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 melphalan, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Ascorbic acid may help melphalan work better by making cancer cells more sensitive to the drug. Giving bortezomib together with ascorbic acid and melphalan may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving bortezomib together with ascorbic acid and melphalan works in treating patients with newly diagnosed multiple myeloma.
