Cyclophosphamide Treatment Options in California

Mantle cell lymphoma (MCL) is a sub-type of non-Hodgkin's lymphoma (NHL) which is generally considered incurable with current therapy. Participants will receive an autologous vaccine against their individual lymphoma after undergoing stem cell transplantation. This vaccination may prolong the time which patients will stay in remission from their disease. Read Less

RATIONALE: Sunitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cyclophosphamide and methotrexate, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving sunitinib together with combination chemotherapy may kill more tumor cells. PURPOSE: This phase I/II trial is studying the side effects and best dose of sunitinib when given together with cyclophosphamide and methotrexate to see how well they work in treating patients with metastatic breast cancer.

Background: * Cyclophosphamide (CP) is a drug approved by the Food and Drug Administration for the treatment of certain cancers. It works by causing DNA damage, resulting in cell death, including cancer cells. * ABT-888 is an experimental drug that has been given to a small number of patients. It works by preventing DNA repair in tumor cells. Objectives: * To test the safety of the combination of ABT-888 and CP, and to determine the dose of each drug that can be given together to patients with cancer. * To see how the body handles ABT-888 when given together with CP * To evaluate the anti-tumor response of the drug combination. Eligibility: * Adults with solid tumors or lymphoid cancers (lymphoma and chronic lymphocytic leukemia) whose disease does not respond to standard treatments. Design: * Patients take ABT-888 by mouth once a day for 7, 14 or 21 days, depending on the dose level assigned to the individual patient. * Patients take CP by mouth once a day every day in 21-day cycles. (Some patients take CP for 14 days only.) * Patients undergo tests and procedures periodically during the study, including: * Clinic visit and physical examination at the beginning of each cycle * Blood and urine tests, electrocardiogram, measurement of vital signs * CT scans, MRI scans or ultrasound tests to check the response of the tumor to treatment * Tumor biopsies (optional) * Bone marrow aspiration and biopsy Read Less

This is a study in which pancreatic cancer patients receive a combination therapy with CART-meso cells and CART19 cells administered at 3 days after one dose of cyclophosphamide. CART-meso cells are patients' own T cells that were modified in the laboratory to express a receptor specific to the mesothelin protein. CART19 cells are patients' own T cells that were modified in the laboratory to express a receptor specific to a protein called CD19. The CD19 protein is expressed on white blood B cells. CART19 cells are expected to attack the B cells and impede the antibody response against CART-meso cells. The investigators hypothesize that this combination therapy may prolong the duration of CART-meso cells in the body. Additionally, one dose of cyclophosphamide may enhance engraftment and persistence of CART cells. Read Less

This pilot clinical trial studies biological therapy in treating patients with acquired immune deficiency syndrome (AIDS)-related lymphoma undergoing stem cell transplant. Giving chemotherapy before a stem cell transplant stops the growth of cancer cells by stopping them from dividing or killing them. After treatment, stem cells are collected from the patient's blood and stored. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy. Giving biological therapy as part of the stem cell transplant may be more effective in treating patients with AIDS-related lymphoma Read Less

RATIONALE: Drugs used in chemotherapy such as cyclophosphamide, prednisone, and methylprednisolone use different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Combining cyclophosphamide and either prednisone or methylprednisolone with rituximab may be effective in treating lymphoproliferative disease following organ transplantation. PURPOSE: Phase II trial to study the effectiveness of combining cyclophosphamide and either prednisone or methylprednisolone with rituximab in treating patients who have Epstein-Barr virus-positive lymphoproliferative disease following organ transplantation.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. It is not yet known which regimen of combination chemotherapy is most effective for lymphoblastic lymphoma. PURPOSE: This randomized phase III trial is studying different regimens of combination chemotherapy to compare how well they work in treating children or adolescents with newly diagnosed stage III or stage IV lymphoblastic lymphoma.

RATIONALE: Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving chemotherapy before surgery may shrink the tumor so that it can be removed during surgery. PURPOSE: Phase II trial to determine the effectiveness of specialized radiation therapy either alone or after chemotherapy and second surgery in treating children who have undergone surgery for localized ependymoma.

This randomized phase III trial is studying tacrolimus, methotrexate, and sirolimus to see how well they work compared to tacrolimus and methotrexate in preventing graft-versus-host disease in young patients who are undergoing donor stem cell transplant for intermediate-risk or high-risk acute lymphoblastic leukemia in second complete remission and high risk acute lymphoblastic leukemia in first remission. Giving chemotherapy, such as thiotepa and cyclophosphamide, and total-body irradiation before a donor stem cell transplant helps stop the growth of cancer cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving tacrolimus, methotrexate, and sirolimus after the transplant may stop this from happening. It is not yet known whether tacrolimus and methotrexate are more effective with or without sirolimus in preventing graft-versus-host disease. Read Less

RATIONALE: Drugs used in chemotherapy work in different ways to stop cancer cells from dividing so they stop growing or die. Peripheral stem cell transplantation may allow doctors to give higher doses of chemotherapy drugs and kill more cancer cells. Biological therapies, such as interferon alfa, use different ways to stimulate the immune system and stop cancer cells from growing. Thalidomide may stop the growth of cancer cells by stopping blood flow to the tumor. Pamidronate may help to reduce the side effects of treatment for multiple myeloma. PURPOSE: This phase II trial is studying combination chemotherapy, peripheral stem cell transplantation, biological therapy, pamidronate, and thalidomide to see how well they work in treating patients with stage I, stage II, or stage III multiple myeloma.

This open-label, randomized, parallel group study will evaluate the efficacy and safety of obinutuzumab in combination with cyclophosphamide, doxorubicin, vincristine, and prednisolone or prednisone (CHOP) chemotherapy versus rituximab (MabThera/Rituxan) with CHOP in previously untreated participants with cluster of differentiation 20 (CD20)-positive diffuse large B-cell lymphoma (DLBCL). Participants will be randomized to receive either obinutuzumab 1000 milligrams (mg) intravenously (IV) every 21 days or rituximab 375 milligrams per square meter (mg/m\^2) IV every 21 days for 8 cycles, in addition to 6-8 cycles of CHOP chemotherapy IV every 21 days. Participants randomized to the obinutuzumab arm will receive an additional two doses on Days 8 and 15 of Cycle 1. Anticipated time on study treatment is 24 weeks. Read Less

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells, but also damages normal cells in the developing brains of children. Combining low-dose radiation therapy in combination with chemotherapy should be effective in treating medulloblastoma while avoiding the long-term side effects of giving higher dose radiation to children with newly diagnosed average risk medulloblastoma.
