Cyclophosphamide Treatment Options

Patients will be asked to participate in this study because patients have been diagnosed with high-risk neuroblastoma, a common childhood cancer which has aggressive features. If left untreated, high-risk neuroblastoma is fatal. Children with high-risk neuroblastoma often respond to current available treatments, but there is a high risk that the cancer will return. This study will test the safety of giving standard induction treatment for high-risk neuroblastoma without one of the drugs commonly used to prevent side effects. Current treatment for high-risk neuroblastoma includes anti-cancer drugs (chemotherapy), surgery, radiation therapy and high-dose chemotherapy with hematopoietic stem cell rescue. Treatment takes about one year to complete and occurs in 3 phases: induction, consolidation, and maintenance. This study is limited to the induction phase of treatment. Induction therapy includes six chemotherapy drugs given in different combinations every 3 weeks for a total of 6 courses. For the past decade, induction chemotherapy has been followed by a drug called granulocyte colony stimulating factor (G-CSF, filgrastim, peg-filgrastim, Neupogen, or Neulasta) to prevent side effects from the chemotherapy. G-CSF is routinely given to patients with high risk neuroblastoma after chemotherapy to stimulate white blood cell production and shorten the time period when the absolute neutrophil count (ANC), a type of white blood cell, is low after chemotherapy. G-CSF is known to shorten the period of low ANC by approximately 3 days. When the ANC is lowest, a patient is most at risk of getting a bacterial infection. Recent lab experiments in mice have shown that neuroblastoma tumor cells may respond to G-CSF by growing faster and metastasizing (spreading to other parts of the body). There have been no clinical trials comparing the survival of children with high risk neuroblastoma with or without G-CSF. This clinical trial is the first step towards giving induction chemotherapy with less G-CSF. The goal of this study is to determine if it is safe to give induction chemotherapy to children with neuroblastoma without giving G-CSF routinely. Read Less

Background: * Stem cells are immature blood cells that grow in the bone marrow and produce all of the cells needed for normal blood and immunity. Stem cells can be taken from one person (donor) and given to another person (recipient) through allogeneic stem cell transplantation. Donor stem cells can then replace the recipients stem cells in the bone marrow, restoring normal blood production and immunity. Most allogeneic transplants now use stem cells collected from the donors blood in a process called peripheral blood stem cell transplantation. * Monocytopenia and mycobacterial infection (MonoMAC) is an immunodeficiency disease that is characterized by a lack of monocytes, a type of white blood cell, and an increased risk of developing mycobacteria infections that may cause tuberculosis. * Allogeneic stem cell transplantation has been used successfully to treat many kinds of immune diseases and cancers that develop in blood or immune system cells. Researchers have been studying a particular kind of stem cell transplantation that uses lower than usual doses of chemotherapy and particular combinations of drugs to improve the results of the procedure for patients with blood-related cancers and pre-cancerous conditions. Objectives: * To determine the safety and efficacy of reduced-intensity hematopoietic stem cell transplants (a particular stem cell transplantation procedure) for treating MonoMAC. Eligibility: * Patients 18-60 years of age who have MonoMAC and who have been matched with a suitable stem cell donor. Design: * Donors and recipients will undergo separate procedures as part of this protocol. * Donors: * National Institutes of Health researchers will take the donor s medical history, perform a physical exam, take blood samples, and explain the procedure. Tests will be performed to check the donors heart, lung, kidney, and liver function. * Donors will receive injections of a drug called filgrastim (G-CSF), which causes stem cells to travel from bone marrow into blood. The G-CSF shots will be given for 5 to 7 days before the collection procedure. * Donors will undergo apheresis to collect white blood cells and stem cells directly from the blood, which can be done as an outpatient procedure. Researchers may consider the alternative of directly collecting bone marrow from the donor, which will require an overnight hospital stay. * Recipients: * Recipients will receive 3 days of pre-transplant chemotherapy and radiation therapy to prepare for the transplant. For 4 days before the transplant, recipients will receive the chemotherapy drug fludarabine, followed by a single dose of radiation therapy, and will also receive the drugs tacrolimus and sirolimus to prevent the donor cells from attacking the recipient s normal tissues. * Recipients will then receive the transplant of donor stem cells and will continue to receive tacrolimus and sirolimus for 3 months after the transplant to prevent the donor cells from attacking the recipient s normal tissues. Recipients will be discharged from the hospital once their condition is stable. * Recipients will visit the NCI clinic regularly for the first 5 months after the transplant, and then less often for at least 5 years. Recipients may receive additional donor immune cells (donor lymphocyte infusion) after the transplant if the study doctors believe they are needed. Read Less

Study of ONTAK and CHOP (chemotherapy drugs) to find out their ability to make Peripheral T-cell lymphoma disappear (for any period of time) and potentially lengthen life. The study will also compare what kind of side effects these drugs cause and how often they occur. The hypothesis is that patients with newly diagnosed peripheral T-Cell lymphoma, when given ONTAK + CHOP, will tolerate the treatment and will have a 20% improvement in response rate when compared to CHOP alone.

Background: - Certain types of cancers, including sarcoma and melanoma, have specific antigens (protein molecules) on their surfaces. Research has shown that producing an immune reaction to these antigens may be able to keep tumors from growing by encouraging the immune system to destroy the tumor cells. By creating a vaccine that contains antigens similar to those found on the cancer cells, researchers hope to cause an immune reaction that targets the cancer cells. However, more research is needed to determine the safety and effectiveness of this type of vaccine treatment. Objectives: - To determine whether a tumor cell vaccine, given to individuals who have had surgery to remove malignant tumors from the chest, can cause an immune reaction that will prevent the tumors from coming back. Eligibility: - Individuals at least 18 years of age who have been diagnosed with cancer that has spread to the lungs, pleura, or mediastinum, and have recently had surgery to remove tumors in the chest. Design: * Participants will be screened with a physical examination and medical history, as well as blood tests and imaging studies. * Participants will have the option to have leukapheresis to collect white blood cells for studies on how the body is responding to the vaccine. Participants who agree to have this procedure will have it before the start of treatment and after the sixth and eighth vaccines. * Seven days before the first vaccine, participants will receive the chemotherapy drugs celecoxib and cyclophosphamide to take twice a day at home. * Participants will receive the experimental vaccine as an injection in the thigh or arm, and may receive it in two shots depending on how many cells are in each vaccine. Participants will receive a diary to monitor medication doses and side effects, as well as additional cyclophosphamide and celecoxib to take at home as directed by the study. * Participants will have one vaccine every month for 6 months, and will have regular blood tests and imaging studies. After the sixth vaccine, participants who have successfully responded to the treatment will have two additional vaccines given 3 months apart. * After the eighth vaccine, participants will have followup visits every 3 months for 1 year and then every 6 months for up to 4 years....

Background: - Certain types of lung, esophageal, or thymic cancers and mesotheliomas have specific antigens (protein molecules) on their surfaces. Research studies have shown that giving a vaccine that contains antigens similar to these may cause an immune response, which may keep tumors from growing. Researchers are also interested in determining whether the chemotherapy drug cyclophosphamide and the anti-inflammatory drug celecoxib may help the vaccine work better, particularly in patients with lung cancer. Objectives: - To evaluate the safety and effectiveness of tumor cell vaccines in combination with cyclophosphamide and celecoxib in patients with cancers involving the chest. Eligibility: - Individuals at least 18 years of age who have had surgery for small cell or non-small cell lung cancer, esophageal cancer, thymoma or thymic carcinoma, and malignant pleural mesothelioma. Design: * Following recovery from surgery, chemotherapy, or radiation, participants will have leukapheresis to collect lymphocytes (white blood cells) for testing. * Participants will receive celecoxib and cyclophosphamide to take twice a day at home, 7 days before the vaccine. * Participants will have the vaccine in the clinical center (one or two shots per month for 6 months), and will stay in the clinic for about 4 hours after the vaccine. Participants will keep a diary at home of any side effects from the vaccine, and will continue to take cyclophosphamide and celecoxib. * One month after the sixth vaccine, participants will provide another blood sample for testing, and if the tests are satisfactory will return to the clinic every 3 months for 2 additional vaccines. * Participants will return to clinic for follow-up physical examinations, lab tests, and scans every 3 months for 2 years and then every 6 months for up to 3 years.

This study is designed to examine whether treating Devic's disease patients with high dose cyclophosphamide together with rabbit antithymocyte globulin (rATG)/rituximab (drugs which reduce the function of the immune system), followed by return of previously collected patient's stem cells will result in improvement in Devic's disease. Stem cells are undeveloped cells that have the capacity to grow into mature blood cells, which normally circulate in the blood stream. The purpose of the intense chemotherapy is to destroy the cells in patient's immune system, which may be causing his/her disease. The purpose of the stem cell infusion is to produce a normal immune system that will no longer attack patient's body. The purpose of study is to examine the safety and efficacy of this treatment. The drugs used in this study treatment are drugs for commonly used for immune suppression. Read Less
