Filter by:This phase II trial studies how well tacrolimus and mycophenolate mofetil works in preventing graft-versus-host disease in patients who have undergone total-body irradiation (TBI) with or without fludarabine phosphate followed by donor peripheral blood stem cell transplant for hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, and TBI before a donor peripheral blood stem cell transplant 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 system 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.
This study involves the use of a drug called Thymoglobulin, which is approved in the USA to treat kidney transplant rejection and in Canada to treat and to prevent kidney transplant rejection. Thymoglobulin is not approved for the treatment or prophylaxis of graft versus host disease in bone marrow transplantation. This study is to evaluate two (2) doses of Thymoglobulin and its safety and effectiveness when used with a "myeloablative" conditioning regimen prior to receiving a stem cell transplant (also called bone marrow transplantation) from a matched, related donor. A myeloablative regimen is typically composed of chemotherapy and radiation and destroys the subject's existing bone marrow. Subjects meeting all inclusion and exclusion criteria and who have a relative with matching (genetically similar) stem cells who are also willing to donate them (i.e. matched-related-donor) are eligible to participate in this study. Following myeloablative therapy, the donor's cells are then transplanted (i.e. infused) into the subject's blood stream. One of the most common complications of this type of transplant is graft-versus-host disease (GvHD). This is a condition where the transplanted donor cells attack the transplant recipient's body. Treatments, such as cyclosporine, are used to minimize the risk of GvHD following stem cell transplantation. To enter this study, subjects must be having a matched-related donor stem cell transplant. If a subject qualifies for entry into this study, he/she will be assigned to receive Thymoglobulin at a dose of 4.5 mg/kg or 8.5 mg/kg. The treatment assignment is random and is not chosen by the subject or their physician. Subjects are admitted to the hospital for the transplant procedure and are treated with Thymoglobulin over 3-5 days just prior to receiving the donor stem cells. The subject will also receive standard GvHD prophylaxis with cyclosporine. Methotrexate, which is commonly used by transplant centers to minimize the risk of GvHD, will not be used in this study. Subjects will be monitored during treatment with Thymoglobulin and during the transplant hospitalization. Additional subject monitoring occurs at month 1, 100 days and 6 months following the transplant. Approximately 60 study subjects from approximately 14 transplant centers in the United States and Canada will be enrolled.
The goal of this clinical research study is to find the highest safe doses of PTK 787 (vatalanib) and Gleevec (imatinib mesylate) that can be given to treat Chronic Myelogenous Leukemia-Blastic Phase (CML-BP), Refractory Acute Myelogenous Leukemia (AML), or Agnogenic Myeloid Metaplasia (AMM). Another goal is to see how effective this combination treatment is.
The purpose of this study is to determine the safety, toxicity and patient tolerance of STA-5312 administered intravenously to patients with relapsed or refractory hematological malignancies and patients with solid tumors.
RATIONALE: Drugs used in chemotherapy, such as bryostatin 1, work in 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. Bryostatin 1 may help rituximab kill more cancer cells by making them more sensitive to the drug. PURPOSE: This phase II trial is studying how well giving bryostatin 1 together with rituximab works in treating patients with B-cell non-Hodgkin's lymphoma or chronic lymphocytic leukemia that has not responded to previous treatment with rituximab.
This phase I trial is studying the side effects and best dose of rebeccamycin analog in treating patients with relapsed or refractory acute myeloid leukemia, myelodysplastic syndrome, acute lymphoblastic leukemia, or chronic myelogenous leukemia in blast phase. Drugs used in chemotherapy, such as rebeccamycin analog, work in different ways to stop cancer cells from dividing so they stop growing or die
RATIONALE: Monoclonal antibodies such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Beta-glucan may increase the effectiveness of rituximab by making cancer cells more sensitive to the monoclonal antibody. PURPOSE: This phase I trial is studying the side effects and best dose of beta-glucan when given together with rituximab in treating young patients with relapsed or progressive lymphoma or leukemia or with lymphoproliferative disorder related to donor stem cell transplantation.
This phase II trial is studying how well CCI-779 works in treating patients with relapsed or refractory chronic lymphocytic leukemia. Drugs used in chemotherapy, such as CCI-779, work in different ways to stop cancer cells from dividing so they stop growing or die
RATIONALE: Drugs used in chemotherapy, such as fludarabine, work in different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies, such as alemtuzumab and rituximab, can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Combining chemotherapy with monoclonal antibody therapy may kill more cancer cells. It is not yet known whether fludarabine is more effective when combined with alemtuzumab or with rituximab in treating chronic lymphocytic leukemia. PURPOSE: Randomized phase II trial to compare the effectiveness of combining fludarabine with either alemtuzumab or rituximab in treating patients who have refractory or relapsed B-cell chronic lymphocytic leukemia.
This is a Phase 3, prospective, multicenter, open-label, randomized, controlled study to evaluate and compare the efficacy and safety of fludarabine plus alemtuzumab versus fludarabine alone as second-line therapy for patients with relapsed or refractory B-cell chronic lymphocytic leukemia (B-CLL). Patients who meet all eligibility criteria and sign the informed consent document may be entered on the study.
