Active clinical trials for "Leukemia, T-Cell"

This phase I/II trial studies the side effects and best dose of panobinostat and everolimus when given together and to see how well they work in treating patients with multiple myeloma, non-Hodgkin lymphoma, or Hodgkin lymphoma that has come back. Panobinostat and everolimus may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

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)

BCX-1777 may stop the growth of cancer cells by blocking the enzymes necessary for their growth. The Phase II trial is designed to study the effectiveness of BCX-1777 in treating patients who have recurrent or refractory advanced T-cell leukemia. Patients will receive an infusion of BCX-1777 on days 1-5. Treatment may be repeated every week for up to six courses. Patients are not required to be hospitalized for the administration of BCX-1777. Some patients may continue to receive an infusion of BCX-1777 twice a week for 6 weeks.

This phase II trial studies how well tipifarnib works in treating patients with relapsed or refractory non-Hodgkin's lymphoma. Tipifarnib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Tipifarnib may be an effective treatment for non-Hodgkin's lymphoma.

This study will examine the use of the humanized Mik-beta-1 (Hu-Mik-beta1) antibody in patients with T-cell large granular lymphocytic leukemia (T-LGL). Patients with T-LGL often have reduced white blood cells, red blood cells, and platelets, and increased numbers of abnormal cells called large granular lymphocytes (LGLs). Patients may have recurrent infections, anemia, or abnormal bleeding. Hu-Mik-beta1 attaches to LGL cells and blocks the action of growth factors called interleukins that stimulate LGL growth. Blocking these interleukins may stop T-LGL leukemia cells from growing. This study will determine the dose and frequency of treatment with Hu-Mik-(SqrRoot) 1 that can safely be given to patients to coat the surface of their leukemic cells with antibody, determine how long the antibody lasts in the blood after injection, and examine the side effects and possible benefits of the drug in these patients. Patients age 18 or older with T-LGL may be eligible for this study. Candidates will be screened with a medical history and physical examination, review of pathology studies, skin biopsy, evaluation of rheumatoid arthritis if present, chest x-ray, computerized tomography (CT) scans and other imaging studies as needed, bone marrow biopsy, and blood and urine tests. Participants will receive a single dose of Hu-Mik-beta1 by a 90-minute infusion through a vein. Groups of patients will be treated with increasing doses (0.5, 1.0, and 1.5 mg/kg) of the antibody. Patients who develop serious drug side effects are taken off the study. The treatment requires a 3- to 4-day hospital stay. In addition to Hu-Mik-(SqrRoot) 1 treatment, patients will undergo the following tests and procedures: Collection of blood for 8 days following the dose of Hu-Mik-beta1 to measure blood levels of the antibody. Follow-up visits of 1 to 2 days at 22, 29, and 43 days after the dose of the antibody and then every 3 months for a total of 9 months. Bone marrow aspirate and biopsy if one has not been done within 6 weeks before entering the study, and a repeat biopsy if complete remission of T-LGL is achieved after completing treatment. For the biopsy, an area of the hip is numbed and a special needle is used to draw bone marrow from the hipbone. Imaging studies, such as chest x-ray and CT scan of the body after completing treatment if the screening scans showed abnormalities due to the T-LGL leukemia. Lymph node biopsy in individuals with enlarged superficial lymph nodes due to T-LGL leukemia to see if the treatment is reaching the leukemia in the lymph nodes. There may or may not be a direct benefit from participating in this study. However, the results may help in the treatment of future patients.

This phase II trial is studying the side effects and best dose of alemtuzumab when given together with fludarabine phosphate and total-body irradiation followed by cyclosporine and mycophenolate mofetil in treating patients who are undergoing a donor stem cell transplant for hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, a monoclonal antibody, such as alemtuzumab, and radiation therapy before a donor stem cell 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 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 cyclosporine and mycophenolate mofetil after the transplant may stop this from happening.

This phase II trial studies how well giving fludarabine phosphate, cyclophosphamide, tacrolimus, mycophenolate mofetil and total-body irradiation together with a donor bone marrow transplant works in treating patients with high-risk hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate and cyclophosphamide, and total-body irradiation before a donor bone marrow transplant helps stop the growth of cancer cells by stopping them from dividing or killing them. Giving cyclophosphamide after transplant may also stop 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

Phase II trial to study the effectiveness of 506U78 in treating patients who have lymphoma that has not been treated previously or that has not responded to previous treatment. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die

The purpose of the study was to determine: (1) the toxicity and maximum tolerated dose (MTD) of humanized anti-Tac (daclizumab), (Zenapax(Registered Trademark)) in patients with adult T-cell leukemia/lymphoma (ATL); (2) to define the dose of Zenapax(Registered Trademark) required to saturate interleukin 2 receptor alpha (IL-2R) alpha in patients with ATL; (3) determine the clinical response to humanized (Hu) anti-Tac (Zenapax(Registered Trademark) of patients with Tac-expressing adult T-cell leukemia; and (4) determine the serum dieaway curve (pharmacokinetics) of infused humanized (Hu)-anti-Tac in patients who have ATL. This study represented an extension of Metabolism Branch National Cancer Institute (NCI) protocols utilizing modifications of the original murine anti-Tac monoclonal antibody (mAb) developed by our group for the treatment of ATL. The scientific basis for these therapeutic studies is that the leukemic cells of patients with ATL express abnormally high levels of the Tac antigen (IL-2R alpha) on their surface whereas resting normal cells including normal T-cells of the patients do not. One presumed mode of action of Hu-anti-Tac in the treatment of ATL involves the interruption of the interaction of interleukin 2 (IL-2) with its growth factor receptor. To be effective in this goal we must maintain saturation of the IL-2 receptors (IL-2R) with humanized anti-Tac thereby preventing IL-2 mediated proliferation and yielding cytokine deprivation and apoptotic cell death of the leukemic cells. Eligible patients with ATL were treated with escalating doses of Zenapax(Registered Trademark) between groups in the Clinical Center of the National Institutes of Health (NIH). Groups of patients received sufficient Zenapax(Registered Trademark) to yield saturation of the IL-2 receptor for a period of 17 weeks. Clinical response was evaluated using routine immunological and clinical evaluation and by monitoring the saturation of the IL-2R and the absolute number of residual circulating malignant cells by fluorescence activated cell sorting (FACS) analysis using two fluorochrome-labeled non-crossreacting antibodies to the IL-2 receptor, anti-Tac and 7G7/B6, as well as antibodies to cluster of differentiation 3 (CD3), cluster of differentiation 4 (CD4), cluster of differentiation 7 (CD7), and cluster of differentiation 8 (CD8). Furthermore, responses were evaluated in patients with leukemia by Southern blot analysis of the arrangement of the T-cell receptor genes and human T-lymphotropic virus type 1 (HTLV-I) integration. Finally, in select patients, to define the pharmacokinetics of the therapeutic antibody, had planned to monitor the serum levels of the infused Hu-anti-Tac (Zenapax(Registered Trademark)) as a function of time. This study is an essential element of our program involving IL-2R-directed therapeutic studies. If as anticipated the therapy with humanized anti-Tac yields some partial and complete remissions in patients with ATL, we will propose that it be used as a single agent for patients with smoldering and chronic ATL and in association with chemotherapeutic agents to provide a novel approach for the treatment of acute and lymphoma forms of ATL. We also plan a future clinical trial where tentative plans also had been made to evaluate the efficacy and toxicity in ATL patients of saturating doses of Zenapax(Registered Trademark) as compared to identical doses of Zenapax(Registered Trademark) given in association with (90)Y-armed 7G7/B6, a non-competing antibody to IL-2R alpha or in combination with chemotherapy.

Background: Adult T-cell leukemia/lymphoma (ATLL) and mycosis fungoides/Sezary syndrome (MF/SS) are cancers that form in the T cells, a type of white blood cell that helps with the body's immune response. A combination of drugs might be able to better treat these cancers than existing therapies. Objective: To test if the drugs interleukin-15 (IL-15) and mogamulizumab are safe and effective to treat people with Adult T-Cell Leukemia and Mycosis Fungoides/Sezary Syndrome (ATLL or MF/SS). Eligibility: People ages 18 and older with relapsed ATLL or MF/SS that has not responded to at least one standard treatment Design: Participants will be screened with: Medical history Physical exam Blood (including human immunodeficiency virus (HIV), hepatitis B and C), urine, lung, and heart tests Bone marrow tests (if needed): A needle inserted in the participants hip will take a small amount of marrow. Computed tomography (CT), positron emission tomography (PET) and/or magnetic resonance imaging (MRI) scans Tumor biopsy (if needed): A needle will take out a small piece of the participants tumor. Participants will get the study drugs by vein for up to six 28-day cycles. They will get IL-15 the first 5 days of each cycle. They will get mogamulizumab on days 1, 8, 15, and 22 of cycle 1 and days 1 and 15 of the other cycles. They will be hospitalized for 1 week in cycle 1. They may need to get a midline catheter. This is a soft tube put into a vein leading to the heart. Participants will have repeats of the screening tests throughout the study. After treatment, participants will have visits every 60 days for 6 months, every 90 days for 2 years, and then every 6 months for 2 years.
