Cyclophosphamide Treatment Options

The purpose of this study is to replace a drug with many side effects, procarbazine, with a new novel drug, vorinostat, in a drug combination for the treatment of patients with diffuse large B-cell lymphoma. Vorinostat is the first of a new type of chemotherapy drug, known as a histone deacetylase inhibitor, to be approved by the Food and Drug Administration. It is approved for the treatment of certain lymphomas of the skin. It alters the cancer cell pathway by preventing cancer cells from reproducing. Vorinostat will be added to a combination of four other effective chemotherapy drugs that have been used for many years for the treatment of diffuse large B-cell lymphoma: rituximab, cyclophosphamide, etoposide and prednisone. The doses of vorinostat will be increased or decreased depending on the side effects that occur in each of the first few patients in the trial to find the safest dose with the least side effects. This is termed the phase I part of the clinical trial. Once the best dose of vorinostat is found, the rest of the patients in the clinical trial will be treated with this dose. This is termed the phase II part of the trial. The object of the trial is to find out what effects, good and/or bad, the combination of vorinostat, rituximab, cyclophosphamide, etoposide and prednisone will have on you and your lymphoma.

RATIONALE: Oxidized glutathione (NOV-002) may stimulate the immune system in different ways and stop tumor cells from growing. Drugs used in chemotherapy, such as doxorubicin, cyclophosphamide, and docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Giving NOV-002 together with chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. PURPOSE: This phase II trial is studying how well giving oxidized glutathione (NOV-002) together with doxorubicin and cyclophosphamide followed by docetaxel works in treating women with newly diagnosed stage II or stage III breast cancer.

Transplantation with stem cells is a standard therapy in many centers around the world. Previous experience with stem cell transplantation therapy for leukemias, lymphomas, other cancers, aplastic anemia and other non-malignant diseases, has led to prolonged disease-free survival or cure for some patients. However, the high doses of pre-transplant radiation and chemotherapy drugs used, and the type of drugs used, often cause many side effects that are intolerable for some patients. Slow recovery of blood counts is a frequent complication of high dose pre-transplant regimens, resulting in a longer period of risk for bleeding and infection plus a longer time in the hospital. Recent studies have shown that using lower doses of radiation and chemotherapy (ones that do not completely kill all of the patient's bone marrow cells) before blood or bone marrow transplant, may be a better treatment for high risk patients, such as those with Dyskeratosis Congenita (DC) or Severe Aplastic Anemia(SAA). These low dose transplants may result in shorter periods of low blood counts, and blood counts that do not go as low as with traditional pre-transplant radiation and chemotherapy. Furthermore, in patients with Dyskeratosis Congenita or SAA, the stem cell transplant will replace the blood forming cells with healthy cells. It has recently been shown that healthy marrow can take and grow after transplantation which uses doses of chemotherapy and radiation that are much lower than that given to patients with leukemia. While high doses of chemotherapy and radiation may be necessary to get rid of leukemia, this may not be important to patients with Dyskeratosis Congenita or SAA. The purpose of this research is to see if this lower dose chemotherapy and radiation regimen followed by transplant is a safe and effective treatment for patients with Dyskeratosis Congenita or SAA.

RATIONALE: Giving chemotherapy and total-body irradiation before a donor umbilical cord blood stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells and natural killer 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. Giving interleukin-2 (IL-2, aldesleukin) after transplant may stimulate the natural killer cells to kill any remaining cancer cells. PURPOSE: This phase II trial is studying the side effects of giving combination chemotherapy together with total-body irradiation followed by interleukin-2 (IL-2, aldesleukin), and umbilical cord blood transplant and to see how well it works in treating patients with relapsed or refractory acute myeloid leukemia.

RATIONALE: Giving chemotherapy and total marrow irradiation before a donor umbilical cord blood or hematopoietic stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening. PURPOSE: This phase I trial is studying the side effects and best dose of total marrow irradiation when given together with combination chemotherapy and umbilical cord blood hematopoietic stem cell transplant in treating patients with acute leukemia, acute myeloid leukemia or multiple myeloma that did not respond to previous therapy.

RATIONALE: Giving chemotherapy before a donor peripheral blood 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. When the healthy stem cells and natural killer (NK) 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. PURPOSE: This clinical trial is studying how well a peripheral stem cell transplant using NK cells from a donor works in treating patients with relapsed acute myeloid leukemia. Read Less

This protocol using busulfan, cyclophosphamide and melphalan has been designed as conditioning therapy for patients receiving stem cell transplantation for acute leukemia or myelodysplastic syndrome (MDS). The hypothesis is that this new regimen will be well tolerated and will cure the patient. Read Less

RATIONALE: Giving low doses of chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cancer cells. It may also 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). PURPOSE: This phase I trial is studying the safety of donor umbilical cord blood transplant after fludarabine phosphate, cyclophosphamide, and total-body irradiation in treating patients with high-risk hematologic cancer (now closed). The Phase II part of this trial is studying whether priming one of two UCB units with C3a facilitates engraftment of the treated unit. Read Less

This trial is proposes to build on our experience and is designed to maximize early (day 3-14) and late (day 60-71) donor-derived natural killer (NK) cell expansion and function in vivo. The proposed platform will allow us the unique opportunity to compare in vivo function from a transplanted umbilical cord blood (UCB) source (presumed to contain NK progenitors requiring "education" in the recipient).
