Stem Cell Transplantation and T-Cell Add-Back to Treat Bone Marrow Malignancies
Description

This study will evaluate the safety and effectiveness of stem cell transplantation in which the donor's T cells (a type of lymphocyte, or white blood cell) are removed and then added back. Certain patients with bone marrow malignancies undergo transplantation of donated stem cells to generate new and normally functioning bone marrow. However, T-cells from the donor may see the patient's cells as foreign and mount an immune response to reject them, causing what is called "graft-versus-host-disease" (GVHD). Therefore, in this protocol, T-cells are removed from the donor cells to prevent this complication. However, because T-cells are important in fighting viral infections as well as any remaining malignant cells (called graft-versus-leukemia effect), the donor T-cells are given to the patient (added back) at a later time after the transplant when they can provide needed immunity with less risk of causing GVHD. Patients between 10 and 55 years of age with acute or chronic leukemia, myelodysplastic syndrome, or myeloproliferative syndrome may be eligible for this study. Prospective participants and their donors are screened with a medical history and physical examination, blood tests (including a test to match for genetic compatibility), breathing tests, chest and sinus x-rays, and tests of heart function. They also undergo a bone marrow biopsy and aspiration. For this procedure, done under local anesthetic, about a tablespoon of bone marrow is withdrawn through a needle inserted into the hipbone. They undergo apheresis to collect lymphocytes for research studies. This procedure involves collecting blood through a needle in the arm, similar to donating a unit of blood. The lymphocytes are then separated and removed by a cell separator machine, and the rest of the blood is returned through a needle in the other arm. Before treatment begins, patients have a central intravenous line (flexible plastic tube) placed in a vein in the chest. This line remains in place during the stem cell transplant and recovery period for drawing and transfusing blood, giving medications, and infusing the donated cells. Preparation for the transfusion includes high-dose radiation and chemotherapy. Patients undergo total body irradiation in 8 doses given in two 30-minute sessions a day for 4 days. Eight days before the transplant, they begin taking fludarabine, and 3 days before the procedure they start cyclophosphamide.

COMPLETED
Collection of Blood, Bone Marrow, Tumor or Tissue Samples
Description

This study will collect biological samples-blood, bone marrow, tumor or other tissue samples-for use in cancer-related research. The specimens will be used for various tests of drug resistance, blood vessel formation, cancer-causing proteins and immune functions. The purpose is to identify steps in the cancer development process that may serve as targets for treatment and to test various therapies for current and future cancer treatment clinical trials. Individuals 18 years of age and older with cancer or a pre-cancerous condition, such as colon polyps or cervical dysplasia, are eligible for this study, as are patients at high risk for cancer. In addition, patients who do not have cancer but require surgery, biopsy or other procedure for another medical reason may be included as normal specimen donors. Participants will have about 40 milliliters (3 tablespoons) of blood drawn upon entering the study and additional 40-ml samples drawn periodically during the course of treatment. No more than 120 ml of blood will be drawn over a 12-month period. Some patients may require a surgical procedure or biopsy (removal of tumor tissue) for medical reasons or as part of their enrollment in a research treatment study. In such cases, a portion of the specimens collected during those procedures will be used for the research studies in this protocol.

COMPLETED
Collection of Blood, Bone Marrow, Tumor, or Tissue Samples From Patients With Cancer to Study Drug Resistance
Description

This study will examine blood, bone marrow, tumor and tissue samples from patients with cancer to study tumor resistance to chemotherapy (drug treatment). Many patients with cancer improve initially with chemotherapy, but then have a disease relapse, after which their tumor no longer responds to treatment. Other patients tumors are drug-resistant from the start. The study will look for "resistance factors"-substances in blood and tissues that render tumors resistant to chemotherapy. The findings may provide information needed to develop methods of combating drug resistance. Patients with cancer who are 18 years or older may be eligible for this study. Participants will have 40 milliliters (3 tablespoons) of blood drawn at the beginning of the study; additional samples will be obtained periodically during the course of treatment. A small sample of tumor or normal tissue will be taken from patients who undergo surgery or tumor biopsy (removal of a small piece of tumor) for medical reasons or as part of a research treatment protocol. Patients who do not require surgery or biopsy may be asked permission to obtain a tumor sample. Depending on the location of the tumor, this may be done by: 1) withdrawing bone marrow through a small needle; 2) removing fluid from the chest or abdomen; 3) removing a small tumor sample through a needle; or 4) removing the sample with a small incision into or around the tumor. These procedures will be done only if they are of low risk to the patient.

RECRUITING
Phase I/II Study to Reduce Post-transplantation Cyclophosphamide Dosing for Older or Unfit Patients Undergoing Bone Marrow Transplantation for Hematologic Malignancies
Description

Background: Certain blood cancers can be treated with blood or bone marrow transplants. Sometimes the donor cells attack the recipient's body, called graft-versus-host disease (GVHD). The chemotherapy drug cyclophosphamide helps reduce the risk and severity of GVHD. Researchers want to learn if using a lower dose of cyclophosphamide may reduce the drug's side effects while maintaining its effectiveness. Such an approach is being used in an ongoing clinical study at the NIH with promising results, but this approach has not been tested for transplants using lower doses of chemotherapy/radiation prior to the transplant. Objective: To learn if using a lower dose of cyclophosphamide will help people have a successful transplant and have fewer problems and side effects. Eligibility: Adults ages 18-85 who have a blood cancer that did not respond well to standard treatments or is at high risk for relapse without transplant, and their donors. Design: Participants may be screened with the following: Medical history Physical exam Blood and urine tests Heart and lung tests Body imaging scans (they may get a contrast agent) Spinal tap Bone marrow biopsy Participants will be hospitalized for 4-6 weeks. They will have a central venous catheter placed in a chest or neck vein. It will be used to give medicines, transfusions, and the donor cells, and to take blood. In the week before transplant, they will get 2 chemotherapy drugs and radiation. After the transplant, they will get the study drug for 2 days. They will take other drugs for up to 2 months. Participants must stay near NIH for 3 months after discharge for weekly study visits. Then they will have visits every 3-12 months until 5 years after transplant. Participants and donors will give blood, bone marrow, saliva, cheek swab, urine, and stool samples for research.

Description

The purpose of the study is to determine if participants who receive the GVHD prophylaxis medication pentostatin will have less severe hepatic toxicities than those receiving MTX. The study is estimated to have sufficient statistical power to ascertain at least a 20% improvement in day 42 NCI CTC grade 2 or above hepatic toxicity-free survival in pentostatin recipients.

COMPLETED
Docetaxel,Carboplatin,Trastuzumab and Bevacizumab for Breast Cancer and Bone Marrow Micrometastases
Description

RATIONALE: Drugs used in chemotherapy, such as docetaxel and carboplatin, 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 trastuzumab and bevacizumab, 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. Giving chemotherapy together with monoclonal antibody therapy may kill more tumor cells. PURPOSE: This clinical trial is studying how well giving docetaxel and carboplatin together with trastuzumab and bevacizumab works in treating patients with stage I, stage II, or stage III breast cancer and bone marrow micrometastases.

Fludarabine Phosphate, Melphalan, Total-Body Irradiation, Donor Stem Cell Transplant in Treating Patients With Hematologic Cancer or Bone Marrow Failure Disorders
Description

This clinical trial is studying how well giving fludarabine phosphate and melphalan together with total-body irradiation followed by donor stem cell transplant works in treating patients with hematologic cancer or bone marrow failure disorders. Giving low doses of chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells or abnormal 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 or abnormal cells (graft-versus-tumor effect)

COMPLETED
Laboratory-Treated Donor Bone Marrow in Treating Patients Who Are Undergoing a Donor Bone Marrow Transplant for Hematologic Cancer
Description

RATIONALE: Giving chemotherapy and total-body irradiation before a donor bone marrow transplant or 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 certain 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. PURPOSE: This randomized phase III trial is studying donor bone marrow that is treated in the laboratory using two different devices to compare how well they work in treating patients who are undergoing a donor bone marrow transplant for hematologic cancer.

Fludarabine, Cyclophosphamide, and Total-Body Irradiation in Treating Patients Who Are Undergoing a Donor Bone Marrow Transplant for Hematologic Cancer
Description

RATIONALE: Giving low doses of chemotherapy, such as fludarabine and cyclophosphamide, and radiation therapy before a donor bone marrow transplant helps stop the growth of cancer cells. Giving chemotherapy or radiation therapy before or after transplant also stops the patient's immune system from rejecting the donor's bone marrow stem cells. The donated stem cells may replace the patient's immune system 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 and mycophenolate mofetil after the transplant may stop this from happening. PURPOSE: This phase II trial is studying how well giving fludarabine and cyclophosphamide together with total-body irradiation works in treating patients who are undergoing a donor bone marrow transplant for hematologic cancer.

The safety of this drug will also be studied. Objectives: Primary: To study the plasma pharmacokinetics of posaconazole in patients with newly diagnosed acute myelogenous leukemia (AML) or high-risk myelodysplastic syndrome (HR-MDS) undergoing induction chemotherapy or relapsed or refractory patients who will receive salvage chemotherapy. Secondary: To evaluate the safety of posaconazole given as prophylaxis.

COMPLETED
Haploidentical Stem Cell Transplantation for Patients With Hematologic Malignancies
Description

Blood and marrow stem cell transplant has improved the outcome for patients with high-risk hematologic malignancies. However, most patients do not have an appropriate HLA (immune type) matched sibling donor available and/or are unable to identify an acceptable unrelated HLA matched donor through the registries in a timely manner. Another option is haploidentical transplant using a partially matched family member donor. Although haploidentical transplant has proven curative in many patients, this procedure has been hindered by significant complications, primarily regimen-related toxicity including graft versus host disease (GVHD) and infection due to delayed immune reconstitution. These can, in part, be due to certain white blood cells in the graft called T cells. GVHD happens when the donor T cells recognize the body tissues of the patient (the host) are different and attack these cells. Although too many T cells increase the possibility of GVHD, too few may cause the recipient's immune system to reconstitute slowly or the graft to fail to grow, leaving the patient at high-risk for significant infection. This research project will investigate the use of particular pre-transplant conditioning regimen (chemotherapy, antibodies and total body irradiation) followed by a stem cell infusion from a "mismatched" family member donor. Once these stem cells are obtained they will be highly purified in an effort to remove T cells using the investigational CliniMACS stem cell selection device. The primary goal of this study will be to determine the rate of neutrophil and platelet engraftment, as well as the degree and rate of immune reconstitution in the first 100 days posttransplant for patients who receive this study treatment. Researchers will also study ways to decrease complications that may occur with a transplant from a genetically mismatched family donor.
