Active clinical trials for "Leukemia, Plasma Cell"

This phase I/II trial studies whether a new kind of blood stem cell (bone marrow) transplant, that may be less toxic, is able to treat underlying blood cancer. Stem cells are "seed cells" necessary to make blood cells. Researchers want to see if using less radiation and less chemotherapy with new immune suppressing drugs will enable a stem cell transplant to work. Researchers are hoping to see a mixture of recipient and donor stem cells after transplant. This mixture of donor and recipient stem cells is called "mixed-chimerism". Researchers hope to see these donor cells eliminate tumor cells. This is called a "graft-versus-leukemia" response.

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 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 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).

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.

This phase I/II trial studies the side effects and best dose of melphalan and total marrow irradiation and how well they work with autologous stem cell transplantation in treating patients with high-risk multiple myeloma. Drugs used in chemotherapy, such as melphalan, 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. Total marrow irradiation is a type of radiation therapy and a form of total body irradiation that may deliver focused radiation to the major marrow sites where cancer cells reside. Giving chemotherapy and total-body irradiation before a peripheral autologous blood stem cell transplant helps kill any cancer cells that are in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. After treatment, stem cells are collected from the patient's blood and stored. More chemotherapy is then given to prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy.

This phase I trial studies side effects of daratumumab, bortezomib, dexamethasone, pegylated liposomal doxorubicin hydrochloride, and lenalidomide in treating participants with plasma cell leukemia. Monoclonal antibodies, such as daratumumab, may interfere with the ability of cancer cells to grow and spread. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as, dexamethasone, pegylated liposomal doxorubicin hydrochloride, and lenalidomide, 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. Giving daratumumab, bortezomib, dexamethasone, pegylated liposomal doxorubicin hydrochloride, and lenalidomide in treating participants with plasma cell leukemia.

This phase I trial studies the side effects and best dose of bendamustine hydrochloride in treating patients with previously treated multiple myeloma. Drugs used in chemotherapy, such as bendamustine hydrochloride, 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.

Bortezomib/Liposomal doxorubicin (V-DD) is preferred to bortezomib single agent in salvage therapy for Multiple Myeloma (MM). The present study is designed to assessment the efficacy and safety study of Bortezomib in combination with Liposomal Doxorubicin and Dexamethasone in treatment of Plasma Cell Leukemia (PCL). Primary study endpoint is the overall response rate (sCR+CR+VGPR+PR). Secondary endpoints is the rate of complete response (sCR+CR), partial remission rate (VGPR + PR), duration of response (DOR), overall survival (OS).
