Filter by:Plasma cell leukaemia is a rare variety of multiple myeloma with a poor prognosis. Plasma cell leukaemia is defined as: at least 2,000 circulating plasma cells per µL for a blood leukocyte count higher than 10,000/µL or 20% of plasma cells for a leukocyte count less than 10,000/µL. Plasma cell leukaemia can be either primary, when it constitutes the first manifestation of the disease, or secondary in the setting of relapsed/refractory multiple myeloma. Primary plasma cell leukaemia (PPL) is a rare disease, representing only 1 to 2% of all cases of multiple myelomas at diagnosis. As the annual incidence of multiple myeloma in France is about 4,000 new cases, an estimated 40 to 80 new cases of PPL would be observed each year. Few data are currently available in the literature concerning the pathophysiology and therapeutic management of PPL, and are derived from retrospective series based small numbers of patients. The prognosis of PPL in response to conventional chemotherapy remains poor with a median survival of 7 to 14 months. However, longer survivals have been obtained with intensive therapy and haematopoietic stem cell transplantation (allogeneic or autologous HSCT). The investigators propose to perform a prospective study of the management of patients with PPL under the age of 70 years, in combination with a laboratory study: 12 weeks of induction chemotherapy by liposomal Bortezomib-Dexamethasone-Doxorubicin (PAD) alternating with Bortezomib-Dexamethasone-Cyclophosphamide (VCD) for a total of 4 cycles. Peripheral blood stem cell collection after mobilization by G-CSF will be performed after high-dose Cyclophosphamide chemotherapy. Autologous HSCT conditioned by high-dose Melphalan will be performed during the following month for all responding patients. During the 3 months after this first autologous HSCT, allogeneic HSCT with attenuated conditioning will be proposed in patients under the age of 66 years in complete remission with a suitable donor, and another systematic autologous HSCT will be proposed in all other patients. For all patients not treated by allogeneic HSCT, consolidation/maintenance therapy will be performed 3 months after the second autologous HSCT: 4 quarterly consolidations with Bortezomib-Lenalidomide-Dexamethasone (VRD) with maintenance by 2 months of Lenalidomide between these cycles, for a total duration of one year. The laboratory assessment will consist of blood and bone marrow samples systematically obtained at diagnosis for plasma cell phenotyping by cytometry, cytogenetics, FISH, study of the gene expression profile and SNParray. A DNA bank and plasma bank will be constituted. The investigators also propose to study residual disease by cytometry (after the first autologous HSCT, before and at the end of the consolidation/maintenance phase), as it increasingly appears to have a major impact on survival in multiple myeloma.
This is a phase II trial using a non-myeloablative cyclophosphamide/ fludarabine/total body irradiation (TBI) preparative regimen followed by a related or unrelated donor stem cell infusion. The primary objective is to evaluate rates of acute graft-versus-host disease (GVHD) grades II-IV and chronic GVHD with an updated GVHD prophylaxis of tacrolimus and mycophenolate mofetil (MMF) with a non-myeloablative preparative regimen in persons with hematologic malignancies.
To see if it is possible to use short-duration tacrolimus after a peripheral blood stem cell transplant in certain malignancies that are considered difficult to engraft.
This phase II trial studies how well pomalidomide, ixazomib citrate, and dexamethasone work in treating patients with previously treated multiple myeloma or plasma cell leukemia. Biological therapies, such as pomalidomide and dexamethasone, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop cancer cells from growing. Ixazomib citrate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving pomalidomide, ixazomib citrate, and dexamethasone together may be more effective in treating multiple myeloma.
This phase Ib trial studies the side effects of combination chemotherapy and donor stem cell transplant followed by ixazomib citrate maintenance therapy in treating patients with multiple myeloma that has returned after a period of improvement and is likely to recur (come back), or spread. Giving chemotherapy before a donor peripheral blood stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Giving ixazomib citrate after the transplant may improve the overall treatment outcome without causing additional toxicities.
This is an open label, multicenter, exploratory, single arm, two-stage study aiming to explore efficacy and safety of lenalidomide and dexamethasone combination (LD) as first line therapy in previously untreated patients with primary Plasma Cell leukemia (PPCL).
This phase I trial studies the side effects and best dose of filanesib when given together with carfilzomib in treating patients with multiple myeloma or plasma cell leukemia that has returned or does not respond to treatment. Drugs used in chemotherapy, such as filanesib, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Carfilzomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving filanesib together with carfilzomib may be a better treatment for multiple myeloma or plasma cell leukemia.
This is a Phase 1 study during which patients with relapsed or refractory multiple myeloma (MM) or plasma cell leukemia (PCL) will receive investigational study drug ARRY-520 and bortezomib, with or without dexamethasone, with granulocyte-colony stimulating factor (G-CSF) support. This study has 2 parts. In the first part, patients will receive increasing doses of study drug (2 dosing schedules will be evaluated) in combination with (1) bortezomib with G-CSF support or (2) bortezomib and dexamethasone with G-CSF support, in order to achieve the highest dose of study drug possible that will not cause unacceptable side effects. Approximately 45 patients from the US will be enrolled in Part 1 (Active, not recruiting). In the second part of this study, patients will receive the best dose(s) and schedule(s) of study drug, in combination with bortezomib ± dexamethasone + G-CSF, determined from the first part of the study and will be followed to see what side effects the combination causes and what effectiveness the combination has, if any, in treating the cancer. Approximately 42 patients from the US will be enrolled in Part 2 (Active, not recruiting).
This phase II trial studies autologous peripheral blood stem cell transplant followed by donor bone marrow transplant in treating patients with high-risk Hodgkin lymphoma, non-Hodgkin lymphoma, multiple myeloma, or chronic lymphocytic leukemia. Autologous stem cell transplantation uses the patient's stem cells and does not cause graft versus host disease (GVHD) and has a very low risk of death, while minimizing the number of cancer cells. Peripheral blood stem cell (PBSC) transplant uses stem cells from the patient or a donor and may be able to replace immune cells that were destroyed by chemotherapy. These donated stem cells may help destroy cancer cells. Bone marrow transplant known as a nonmyeloablative transplant uses stem cells from a haploidentical family donor. Autologous peripheral blood stem cell transplant followed by donor bone marrow transplant may work better in treating patients with high-risk Hodgkin lymphoma, non-Hodgkin lymphoma, multiple myeloma, or chronic lymphocytic leukemia.
This is a 2-phase study during which patients with relapsed or refractory multiple myeloma (MM) or plasma cell leukemia (PCL), who have already received at least two previous treatments, will receive investigational study drug ARRY-520. The study has 3 parts. In the first part of the study, Phase 1, patients will receive increasing doses of study drug, with or without granulocyte-colony stimulating factor (G-CSF) support, in order to achieve the highest dose possible that will not cause unacceptable side effects. Approximately 30 patients from the US will be enrolled in Part 1 (Active, not recruiting). In the second part of the study, Phase 2, patients will receive the best dose of study drug determined from the first part of the study and will be followed to evaluate what side effects the study drug causes and what effectiveness it has, if any, in treating the cancer. Approximately 30 patients from the US will be enrolled in Part 2 (Active, not recruiting). In the third part of the study, Phase 2 with Dexamethasone, patients will receive the best dose of the study drug determined from the first part of the study, in combination with dexamethasone, and will be followed to evaluate what side effects the combination causes and what effectiveness the combination has, if any, in treating the cancer. Approximately 50 patients from the US will be enrolled in Part 3 (Active, not recruiting).
