Active clinical trials for "Neoplasms, Plasma Cell"

RATIONALE: Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Removing the T cells from the donor cells before transplant may stop this from happening. Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help destroy any remaining cancer cells (graft-versus-tumor effect). PURPOSE: This phase II trial is studying T-cell depletion in donor stem cell transplant followed by delayed T cell infusions in treating patients with hematologic cancer or other disease.

RATIONALE: Biological therapies, such as anti-thymocyte globulin, may stimulate the immune system in different ways and stop cancer cells from growing. Drugs used in chemotherapy, such as melphalan, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Anti-thymocyte globulin may also make cancer cells more sensitive to melphalan. Giving anti-thymocyte globulin together with melphalan may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving anti-thymocyte globulin together with melphalan works in treating patients with relapsed multiple myeloma.

RATIONALE: Drugs used in chemotherapy, such as melphalan, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Radiolabeled monoclonal antibodies can find cancer cells and carry cancer-killing substances to them without harming normal cells. A stem cell transplant using stem cells from the patient may be able to replace blood-forming cells that were destroyed by the chemotherapy and radiolabeled monoclonal antibody. PURPOSE: This randomized phase II trial is studying how well high-dose melphalan works when given with or without radiolabeled monoclonal antibody in treating patients with multiple myeloma undergoing an autologous stem cell transplant.

RATIONALE: A donor peripheral stem cell transplant helps stop the growth of 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. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer cells as not belonging in the patient's body and destroy them. Giving an infusion of donor T cells may helps stop the patient's immune system from rejecting the donor's stem cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of donor T cells in treating patients with high-risk hematologic cancer who are undergoing donor peripheral blood stem cell transplant. Note: Only Phase I portion of study was performed. Due to slow accrual, study was closed before Phase II portion of study.

The purpose of this study is to evaluate the effectiveness and safety of bortezomib in participants previously treated for multiple myeloma (cancer of plasma cells in bone marrow causing numerous tumors and characterized by the presence of abnormal proteins in the blood) with limited kidney function.

RATIONALE: Drugs used in chemotherapy, such as pegylated liposomal doxorubicin hydrochloride and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the cancer. Giving pegylated liposomal doxorubicin hydrochloride together with bortezomib, cyclophosphamide, and dexamethasone may kill more cancer cells. PURPOSE: This phase I/II trial is studying the side effects of giving pegylated liposomal doxorubicin hydrochloride together with bortezomib, cyclophosphamide, and dexamethasone and to see how well it works in treating patients with multiple myeloma

The purpose of this study is to determine whether the association of ZMP is safe and provides benefits in patients with relapsed/refractory MM.

RATIONALE: A peripheral stem cell transplant or an umbilical cord blood transplant from a donor may be able to replace blood-forming cells that were destroyed by chemotherapy or radiation therapy. Giving an infusion of the donor's white blood cells (donor lymphocyte infusion) after the transplant may help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells can make an immune response against the body's normal cells. Methotrexate, cyclosporine, tacrolimus, or methylprednisolone may stop this from happening. PURPOSE: This clinical trial is studying how well a donor stem cell transplant or donor white blood cell infusions work in treating patients with hematologic cancer.

RATIONALE: Giving CpG 7909 after an autologous stem cell transplant may make a stronger immune response and prevent or delay the recurrence of cancer. PURPOSE: This phase I trial is studying the side effects and best dose of CpG 7909 in treating patients who have undergone autologous stem cell transplant.

The current study is being conducted to evaluate the possibility that a different schedule of bortezomib, doxorubicin HCl liposome, and dexamethasone might decrease the incidence of peripheral neuropathy yet maintain similar efficacy and allow maintenance of bortezomib dosing for a longer period.
