Active clinical trials for "Neoplasms, Plasma Cell"

This is a study of pembrolizumab (MK-3475) in combination with lenalidomide and low-dose dexamethasone in participants with refractory or relapsed and refractory Multiple Myeloma (rrMM), and in combination with carfilzomib and low-dose dexamethasone in participants with relapsed or refractory Multiple Myeloma (rMM). This study was being done to find the maximum tolerated dose (MTD)/maximum administered dose (MAD) and recommended Phase 2 dose (RP2D), and to evaluate the safety and tolerability of pembrolizumab when given in combination with standard of care (SOC) treatments in participants with rrMM or rMM. Preliminary efficacy data will also be assessed. There was no primary hypothesis associated with this study. On 03-Jul-2017, the United States Food and Drug Administration (US FDA) placed the rrMM cohort of this protocol on clinical hold based on safety data from two other pembrolizumab protocols: MK-3475-183 (NCT02576977) and MK-3475-185 (NCT02579863) presented to the Data Monitoring Committee. On 15-Sep-2017, the US FDA placed the rMM cohort of this study on partial clinical hold. Enrollment was stopped and will not be reopened. Participants who are deriving clinical benefit were allowed to continue receiving study treatment until protocol-specific end of treatment, and then progress into long term safety and survival follow up. Participants who are not deriving clinical benefit, must stop study treatment and move into the long term safety and survival follow up.

This phase I/II trial studies the side effects and best dose of lenalidomide and pidilizumab and to see how well they work in treating patients with multiple myeloma that has come back (relapsed) or has not responded to treatment (refractory). Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing. Monoclonal antibodies, such as pidilizumab, can block cancer growth by blocking the ability of cancer to grow and spread. Giving lenalidomide with pidilizumab may work better in treating relapsed or refractory multiple myeloma.

This randomized pilot phase II trial studies how well giving dalteparin, lenalidomide, and low-dose dexamethasone together works in treating patients with previously untreated multiple myeloma. Anticoagulants, such as dalteparin, may help prevent blood clots from forming in patients being treated with lenalidomide and dexamethasone for multiple myeloma. Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing. 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 dalteparin, lenalidomide, and dexamethasone together may be an effective treatment for multiple myeloma

There is a great need for treatment options in patients with multiple myeloma (MM) after failure of the lenalidomide/dexamethasone regimen as there is no established standard active therapy for these patients. Combining nelfinavir, a drug targeting both the proteasome and PI3K/Akt pathway, with lenalidomide, may restore lenalidomide-sensitivity to the disease as has been shown in vivo for the PI3K/Akt inhibitor perifosine and the proteasome inhibitor bortezomib. Patients expected to be included in the trial are heavily pretreated and might not be candidates for further intensive therapies. The combination of nelfinavir with lenalidomide/dexamethasone offers also to these patients an alternative. Preliminary experiences in another SAKK trial with the combination of bortezomib and nelfinavir are positive with few side effects with nelfinavir doses of up to 1875 mg twice daily (bid). For the phase I part of the trial a starting dose of 1250 mg nelfinavir bid was chosen, since the necessary plasma concentration of nelfinavir will not be reached with lower doses. In case of progression during or after the trial treatment any other lenalidomide- or bortezomib-based chemotherapy combination could be an option for the patient. However, the addition of a chemotherapeutic drug like cyclophosphamide or doxorubicin has known side effects like hematological toxicities, nausea, vomiting and hair loss. The aim of this trial is to demonstrate that the combination of nelfinavir with lenalidomide/dexamethasone is safe (phase I, dose escalation of nelfinavir) and active (phase II). Patients who do not respond to trial medication will stop trial treatment after 4 months of therapy at the latest. If the combination of nelfinavir with lenalidomide/dexamethasone should prove to be safe and efficient in treatment of lenalidomide-refractory MM, this would be the first orally available treatment for these patients and establish a new class of drugs (human immunodeficiency virus (HIV) protease inhibitors) as active antineoplastic agents in MM. In addition this would establish the concept of "re-sensitizing" patients to lenalidomide therapy and demonstrate the effect of nelfinavir on proteasomal degradation and Akt phosphorylation in cancer patients in vivo.

Background: - Cancer development is associated with problems in immune system functions, which prevent the body from attacking and destroying the abnormal cells that lead to tumor growth. Research has suggested that certain white blood cells, known as Th1 (type 1 T helper cells) and Th2 T cells (type 2 T helper cells), are affected in individuals with some kinds of cancer -- when the proportion of Th2 cells is greater than Th1 cells, the immune systems ability to fight off the growth of malignant tumors is weakened. Researchers are interested in determining if an infusion of specially modified Th1 cells, in addition to stem cell transplant, is a safe and effective treatment for individuals with forms of multiple myeloma that might not respond well to standard treatments alone. Objectives: - To determine the safety and effectiveness of the infusion of modified Th1 white blood cells, in conjunction with standard treatment, as a treatment for individuals who have been diagnosed with high-risk forms of multiple myeloma. Eligibility: Individuals age 18 to 75 who have been newly diagnosed with high-risk multiple myeloma and who have received no or minimal treatment (Cohort A). Individuals age 18 to 75 who have relapsed multiple myeloma, as defined by measurable disease after at least 2 prior treatment regimens. Design: Participants will be screened with a medical history, physical examination, blood and urine tests, and imaging studies. Some participants may also have a bone marrow or other type biopsy to evaluate the state of their disease. White blood cells will be collected from the participants through an apheresis procedure, which will collect and separate the white blood cells and return the rest of the blood to the participant. The collected cells will be grown and expanded under special conditions in the laboratory and stored frozen until participants receive standard of care treatment for multiple myeloma, including a stem cell transplant. Participants will receive an infusion of the modified Th1 cells a few weeks after the transplant, and will remain in the hospital for a few days after receiving the cells to monitor the possible immediate effects of the treatment. Participants will have regular follow-up visits to study the long-term effects of the modified Th1 cell infusion.

The study involves the use of a targeted form of radiation, in addition to standard high dose chemotherapy and stem cell transplant for multiple myeloma. The use of targeted radiation is designed to kill more multiple myeloma cells while avoiding the side effects of standard radiation. This type of targeted radiation (also known as radioimmunotherapy) has been approved by the Food and Drug Administration (FDA) for the treatment of a related disease, lymphoma under the trade name, Zevalin©. Zevalin© has been added to high dose chemotherapy and stem cell transplants for patients with lymphoma and is now being studied in this clinical trial for patients with multiple myeloma. This trial is only available at Tufts Medical Center. The proposed clinical trial will test whether CD20-targeted radio-immunotherapy can be safe and effective when integrated into a standard regimen of myeloablative chemotherapy and autologous stem cell rescue in patients with measurable disease prior to high dose chemotherapy and autologous stem cell transplant for multiple myeloma.

This is an open label phase I/II trial to determine the safety and the biologic activity of the bendamustine, bortezomib and pegylated liposomal doxorubicin combination.

The purpose of this study is to improve the efficacy of the HDC regimen by adding a novel, "targeted" means administering a variation of total body irradiation (TBI) radiation i.e., total skeletal irradiation (TSI) administered by helical tomotherapy (HT) before, and in addition to the current standard of HDC, at a dose of 200 mg/m2 (HDMel200). The underlying postulate of this endeavor is that TSI-HT will provide additional cytoreduction to HDMel alone, without producing additional (serious) toxicity. We will utilize a classical Phase I study design (i.e., dose escalation) in myeloma patients undergoing AHSCT2 to define a maximum tolerated dose (MTD) and dose limiting toxicity (DLT). Finally, although comparisons to other therapies are not typical (and/or feasible) for a Phase I study, we will compare, whenever possible, both the toxicity and the antimyeloma activity of the AHSCT2 to AHSCT1. This protocol will standardize, as much as possible the use of AHSCT2 both as a "tandem" and "salvage" procedure. Since sufficient AHSC (CD34+ cells) are routinely collected in adequate numbers for multiple AHSCTs, but recently used infrequently, it is important to work towards defining the optimal utilization of this resource.

Background: Recent studies have shown that smoldering multiple myeloma has a high risk of progressing to multiple myeloma, an aggressive type of bone marrow cancer, within 5 years of diagnosis. People with smoldering multiple myeloma have abnormal blood test results that show a high level of monoclonal protein (M-protein) in the blood and of plasma cells in the bone marrow. There are currently no known effective treatments to prevent smoldering multiple myeloma from developing into multiple myeloma, and there are no known tests for determining whether an individual with smoldering multiple myeloma will develop multiple myeloma. Certain cells in the immune system, known as natural killer (NK) cells, are active against multiple myeloma. The experimental drug anti-killer cell immunoglobulin-like receptor (anti-KIR) has been shown to help NK cells kill multiple myeloma cells. Researchers are interested in determining whether anti-KIR can be given to individuals with smoldering multiple myeloma to improve their abnormal blood test results. Objectives: - To evaluate the safety and effectiveness of anti-KIR as a treatment for abnormal blood test results related to smoldering multiple myeloma. Eligibility: - Individuals at least 18 years of age who have been diagnosed with smoldering multiple myeloma. Design: Participants will be screened with a physical examination and medical history, and will provide baseline blood, urine, and bone marrow samples before beginning the study drug. Participants will receive anti-KIR intravenously for 1 hour, and will be closely monitored for 24 hours after receiving the first dose. If there are no serious side effects, participants will receive five additional anti-KIR doses, one every other month, for a total of six treatment cycles. Participants will have monthly visits to provide additional blood and urine samples, and may have additional bone marrow biopsies as directed by the study researchers. Participants will have followup visits every 3 to 6 months for up to 5 years after receiving anti-KIR treatment.

The primary objective of this observational study is to identify the molecular profiles and clinical characteristics that define subsets of myeloma patients during the course of the disease.
