Active clinical trials for "Neoplasms, Plasma Cell"

RATIONALE: Monoclonal antibodies such as rituximab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Biological therapies such as interferon alfa-2b use different ways to stimulate the immune system and stop cancer cells from growing. PURPOSE: Phase II trial to study the effectiveness of rituximab or interferon alfa-2b in treating patients who have chronic lymphocytic leukemia or multiple myeloma in remission.

This is a single arm, multi-institution (1) Hackensack Meridian Health at Hackensack, New Jersey (NJ) (2) Jersey Shore Medical Center, Neptune, NJ and (3) Georgetown/Lombardi Cancer Center) phase II study of the combination of pembrolizumab, belantamab, and dexamethasone in patients with triple class refractory multiple myeloma.

This phase I trial studies the side effects of NY-ESO-1 TCR engineered peripheral blood mononuclear cells (PBMC) and peripheral blood stem cells (PBSC) after melphalan conditioning regimen in treating participants with multiple myeloma that has come back or does not respond to treatment. The melphalan conditioning chemotherapy makes room in the patient?s bone marrow for new blood cells (PBMC) and blood-forming cells (stem cells) to grow. Giving NY-ESO-1 TCR PBMC and stem cells after the conditioning chemotherapy is intended to replace the immune system with new immune cells that have been redirected to attack and kill the cancer cells and thereby improve immune system function against cancer. Giving NY-ESO-1 TCR PBMC and PBSC after melphalan may work better at treating multiple myeloma.

This is an open-label phase I study in which dovitinib is given in combination with bortezomib and dexamethasone. Dovitinib dose escalation is planned in order to determine its maximum tolerated dose when given in this combination.

This phase II trial studies the side effects and how well lower doses of bortezomib, dexamethasone, and cyclophosphamide work in treating older patients with multiple myeloma. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cyclophosphamide and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving cyclophosphamide daily may kill more cancer cells. Giving bortezomib, cyclophosphamide, and dexamethasone may be an effective treatment for multiple myeloma.

Background: - Smoldering multiple myeloma (SMM) is a condition that can lead to multiple myeloma, a type of blood cancer. In many high-risk cases, SMM can develop into multiple myeloma in less than 2 years. The current standard of care for SMM is follow-up without treatment until multiple myeloma develops. However, some drugs are being studied to see if they can slow down or prevent the disease from progressing. One such drug is MLN9708. It has shown some results against multiple myeloma. Researchers want to combine MLN9708 with dexamethasone to see how it works against high-risk SMM. Objectives: - To see if MLN9708 with dexamethasone is a safe and effective treatment for high-risk smoldering multiple myeloma. Eligibility: - Individuals at least 18 years of age who have high-risk smoldering multiple myeloma. Design: Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Imaging studies and a bone marrow biopsy may also be performed. Participants will take MLN9708 and dexamethasone on a regular schedule for 28 days. They will take each drug four times at regular intervals during each cycle of treatment. Treatment will be monitored with frequent blood tests and imaging studies. Participants will have 12 cycles of treatment. After four cycles, patients will be recommended to have their own stem cells collected and stored. This will allow the potential application of a highdose melpahalan/autologous stem cell transplant in the event there is a need in the future (not part of this study). After 12 cycles, participants will keep taking MLN9708 as long as the disease does not progress and the side effects are not too severe.

The purpose of this study is to determine the safety and in vivo persistence and expansion of autologous and expansion of autologous, ex vivo expanded-natural killer(ENK) cells.

This study will compare the effectiveness and safety of maintenance therapy with continuous bortezomib, lenalidomide, and dexamethasone (VRD) compared to maintenance therapy that alternates VRD with Elotuzumab, lenalidomide, and dexamethasone (Elo RD) every eight weeks.

This study will evaluate the ability of Expanded Natural Killer (ENK) cells to treat multiple myeloma when administered as part of a regimen consisting of Elotuzumab and a stem cell transplant. Natural killer cells are a special type of white blood cells that are already present in the body which have the ability to kill myeloma cells. In this study, natural killer cells will be collected and then treated in a laboratory to activate and 'expand' the number of cells to increase the dose and the anti-myeloma activity of the cells before they are transfused back into the subject. Elotuzumab is a protein drug approved by the United States Food and Drug Administration (FDA) for patients with previously treated multiple myeloma and works by activating natural killer cells already present in the body and targeting a protein called SLAMF7 which is present on both natural killer cells and myeloma cells. The investigators hope that administering Elotuzumab in combination with ENK cells will enhance the anti-myeloma activity of the ENK cells.

The purpose of this study is to evaluate the efficacy and safety of paclitaxel in combination with cyclophosphamide and dexamethasone in chinese patients with relapsed/refractory multiple myeloma.
