Cyclophosphamide Treatment Options in Maryland

Background: - Chronic Granulomatous Disease (CGD) causes immune system problems. Treatment is usually a bone marrow transplant from a fully matched donor. Researchers want to try using partially matched donors for patients who do not have a fully matched donor available. The researchers will also use the drug cyclophosphamide to try to improve the outcomes when using a partially matched donor. Objective: - To learn the effectiveness of using cyclophosphamide with a transplant from a partially matched donor in treating CGD. Eligibility: - Recipients: age 2-65 with CGD with an ongoing infection that has not been cured by standard treatment and no fully matched donor available in an appropriate timeframe. Design: * Recipients will: * be admitted to the hospital 2 weeks before transplant. * be screened with blood and urine tests, breathing and heart health tests, X-rays, and/or magnetic resonance imaging. They may have a bone marrow aspiration and biopsy. * meet with a social worker and dentist. * get chemotherapy, radiation, and other medicines. * get an intravenous (IV) catheter in their chest. * have the transplant. * get more medicines and standard supportive care. * have blood drawn frequently. * have to stay in the Washington, D.C. area for 3 months post-transplant. * be followed closely for the first 6 months, and then less frequently for at least 5 years.

This is a feasibility study to examine combination therapy with Trastuzumab (T), Cyclophosphamide (CY), and an allogeneic GM-CSF-secreting whole cell breast cancer vaccine in patients with Stage IV HER-2/neu-overexpressing breast cancer. The main purposes of this study are to test the safety, clinical benefit, and bioactivity of vaccine therapy in combination with Cyclophosphamide and Trastuzumab in patients with HER-2/neu-overexpressing Stage IV breast cancer. This study will also to test whether the Cyclophosphamide can eliminate the suppressive influence of regulatory T cells, and whether Trastuzumab can increase antigen processing and presentation. These drug activities may make the immune system react better and enhance the effects of the vaccine in treating breast cancer. The vaccine consists of two irradiated allogeneic mammary carcinoma cell lines genetically modified to secrete human granulocyte-macrophage colony stimulating factor (GM-CSF). This open label, single arm study is designed to recruit up to 40 subjects to identify 20 research subjects with HER-2/neu-overexpressing Stage IV breast cancer eligible for study treatment.

RATIONALE: Giving chemotherapy before a donor stem cell transplant using stem cells that closely match the patient's stem cells, helps stop the growth of cancer cells. It also stops 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 antithymocyte globulin before transplant and cyclosporine, tacrolimus, and methotrexate before and after transplant may stop this from happening. PURPOSE: Natural Killer (NK) cells from the donor's bone marrow may be important in fighting leukemia. Bone marrow donors can be selected based on the type of NK cells they have, specifically the killer immunoglobulin receptor (KIR) type. This study provides information on KIR type from potential donors, which can be used in selecting the bone marrow donor. This phase II trial of unrelated donor stem cell transplant in patients with high risk AML (monosomy 7, -5/5q-, high FLT3-ITD AR, or refractory or relapsed AML) in which KIR typing of the patients and potential donors will be available to the treating transplant physician at the time of donor selection.

This phase II/III trial is studying the side effects and how well giving dasatinib together with combination chemotherapy works in treating young patients with newly diagnosed acute lymphoblastic leukemia (ALL). Dasatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving dasatinib together with combination chemotherapy may kill more cancer cells. 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

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.

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....

RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy used to kill tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of cyclophosphamide when given together with combination chemotherapy and a peripheral stem cell transplant in treating patients with malignant solid tumors.

RATIONALE: Vaccines made from gene-modified tumor cells may help the body build an effective immune response to kill pancreatic cancer cells. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving vaccine therapy together with cyclophosphamide may kill more tumor cells. It is not yet known whether vaccine therapy is more effective with or without cyclophosphamide in treating patients with pancreatic cancer. PURPOSE: This randomized clinical trial is studying the side effects of vaccine therapy and to see how well it works when given with or without cyclophosphamide in treating patients undergoing chemotherapy and radiation therapy for stage I or stage II pancreatic cancer that can be removed by surgery.

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as cyclophosphamide and doxorubicin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving radiation therapy together with cyclophosphamide and doxorubicin after surgery may kill any tumor cells that remain. PURPOSE: This phase I/II trial is studying the side effects of radiation therapy when given together with cyclophosphamide and doxorubicin and to see how well they work in treating women with stage I or stage II breast cancer who have undergone surgery.

RATIONALE: Vaccines made from gene-modified tumor cells may help the body build an immune response to kill tumor cells. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Cetuximab may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving vaccine therapy together with cyclophosphamide and cetuximab may kill more tumor cells. PURPOSE: This phase II trial is studying how well vaccine therapy works when given together with cyclophosphamide and cetuximab in treating patients with metastatic or locally advanced pancreatic cancer.
