Active clinical trials for "Neoplasms, Plasma Cell"

RATIONALE: When irradiated lymphocytes from a donor are infused into the patient they may help the patient's immune system kill cancer cells. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving irradiated donor lymphocytes together with rituximab may kill more cancer cells. PURPOSE: This clinical trial is studying the side effects and how well giving irradiated donor lymphocytes together with rituximab works in treating patients with relapsed or refractory lymphoproliferative disease.

RATIONALE: Paricalcitol may cause multiple myeloma cells to look more like normal cells, and to grow and spread more slowly. Paricalcitol may also stop the growth of the cancer cells by blocking blood flow to the cancer. Zoledronate may delay or prevent bone metastases in patients with multiple myeloma. Giving paricalcitol together with zoledronate may be an effective treatment for multiple myeloma or other plasma cell disorders. PURPOSE: This clinical trial is studying the side effects and best dose of paricalcitol when given with zoledronate in treating patients with relapsed or refractory multiple myeloma or other plasma cell disorders.

RATIONALE: Drugs used in chemotherapy, such as arsenic trioxide, dexamethasone, and ascorbic acid, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells. Sometimes when chemotherapy is given, it does not stop the growth of cancer cells. The cancer is said to be resistant to chemotherapy. Giving arsenic trioxide together with chemotherapy may reduce drug resistance and allow the cancer cells to be killed. Thalidomide may stop the growth of multiple myeloma by blocking blood flow to the cancer. Giving arsenic trioxide together with thalidomide, dexamethasone, and ascorbic acid may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving arsenic trioxide together with thalidomide, dexamethasone, and ascorbic acid works in treating patients with relapsed or refractory multiple myeloma.

Blood disorders such as leukemia or lymphoma or hemoglobinopathies can benefit from receiving an allogeneic (meaning that the cells are from a donor) stem cell transplant. Stem cells are created in the bone marrow. They grow into different types of blood cells that the body needs, including red blood cells, white blood cells, and platelets. In a transplant, the body's stem cells would be killed and then replaced by stem cells from the donor. Usually, patients are given very high doses of chemotherapy (drugs which kill cancer cells) prior to receiving a stem cell transplant. However, patients that are older, have received several prior treatments, or have other organ diseases are at a high risk of getting life-threatening treatment-related side effects from high doses of chemotherapy. Over the past several years, some doctors have begun to use lower doses of chemotherapy for preparing patients for a stem cell transplant. A condition that can occur after a stem cell transplant from a donor is Graft Versus Host Disease (GVHD). It is a rare but serious disorder that can strike persons whose immune system is suppressed and have received either a blood transfusion or a bone marrow transplant. Symptoms may include skin rash, intestinal problems similar to inflammation of the bowel and liver dysfunction. This research study uses a combination of lower-dose chemotherapy agents that is slightly different from those that have been used before. The medicines that will be used in this study are Fludarabine, Busulfan, both chemotherapy medicines, and Campath. Campath is a monoclonal antibody (a type of substance produced in the laboratory that binds to cancer cells). It helps the immune system see the cancer cell as something that needs to be destroyed. This research study will help us learn if using Fludarabine, Busulfan and Campath prior to an allogeneic stem cell transplant can provide treatment for blood disorders while decreasing the incidence of side effects.

This study will evaluate the efficacy and safety of LBH589B in adult patients with multiple myeloma who have received at least two prior therapies and are refractory to their last therapy. Patients must have received in prior therapy either bortezomib or lenalidomide

The purpose of this study it to evaluate the efficacy of PTK787/ZK 222584, in inducing at least a 50% reduction in paraprotein in patients with multiple myeloma whose paraprotein levels are < 5 g/dL following high dose chemotherapy (HDCT) and autologous stem cell transplantation (ASCT).

An Open-Label Study of the Efficacy and Safety of Oral CEP-701 for the Treatment of Patients with Advanced Multiple Myeloma.

To determine the overall response rate (CR+PR) of patients with relapsed or refractory multiple myeloma treated with clofarabine.

This clinical study is being conducted at multiple sites to determine the activity, safety, and tolerability of XL999 when given weekly to patients with relapsed or refractory multiple myeloma. XL999 is a small molecule inhibitor of cellular factors including VEGFR, PDGFR, and FGFR that may be involved in multiple myeloma.

In Phase I, patients will receive a combination of PS-341 (Velcade) and R115777 (Zarnestra) to determine the dose limiting toxicity (DLT). Once DLT is determined, patients in Phase II will be receive the maximum tolerated dose (MTD) to complete 8 cycles of therapy. Treatment will continue if there is evidence of continued response for 8 cycles. Patients will receive follow up to include normal laboratory evaluations at least every 3 months and a skeletal survey will be performed at least every 6 months.
