Active clinical trials for "Leukemia, T-Cell"

Background: The human T-cell leukemia virus 1 (HTLV-1) causes adult T-cell leukemia (ATL). Infection does not immediately cause ATL, but it can develop over time. ATL is a rare and aggressive type of cancer that disrupts the body's ability to control the HTLV-1 virus. Infected T lymphocytes that are transformed by HTLV-1 into malignant ATL cell have constitutively activated Interleukin-2 (IL-2), IL-9 and IL-15 production pathways that function as autocrine and paracrine stimulators of these cells by stimulating these cells through the Janus Kinase (JAK) 1 and 3/Signal transducer and activator of transcription 5 (STAT5) pathways. Ruxolitinib is a drug that has been approved to treat bone marrow disorders. Ruxolitinib is a tyrosine kinase inhibitor that disrupts signaling through the JAK 1 and 2/STAT3 and 5 pathways and have potential as a treatment for ATL. Researchers want to see if ruxolitinib can be a safe and effective treatment for ATL. Initially this trial was designed as a single dose level phase II trial with ruxolitinib given at the dose approved for the treatment of primary myelofibrosis, post-polycythemia vera myelofibrosis and post-essential thrombocythemia myelofibrosis. Clinical and correlative laboratory data demonstrated limited inhibition and impact on the subject's disease with the standard 20 mg twice daily dose. Given that the manufacturers of ruxolitinib had safety data for administering ruxolitinib to normal healthy volunteers at doses up to 50 mg twice or 100 mg once daily, the trial was reconfigured as a phase I dose escalation trial giving these higher doses on the twice daily schedule Objectives: Initial Phase II design: Define clinical or objective response rate for the 20 mg twice daily dose of Ruxolitinib. Define safety profile, Time to progression and survival time. Subsequent Phase I dose escalation with expansion cohort treated at the MTD or MAD: Determine the maximum tolerated dose (MTD) and clinical response rate for ruxolitinib administered at the higher dose levels. Determine safety profile, time to progression To test the safety and effectiveness of ruxolitinib for adult T-cell leukemia. Eligibility: - Individuals at least 18 years of age who have ATL caused by HTLV-1. Design: Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Imaging studies will also be performed. Participants will take ruxolitinib twice a day for 28 days. They will have blood tests on days 1, 14, and 28. These tests will look at the levels of HTLV-1 in the blood. Participants will have a final blood test about 2 weeks later. Treatment will also be monitored with imaging studies. Participants who have a partial response during treatment may be able to start taking ruxolitinib again after the final blood test. They will continue to take ruxolitinib for as long as it is effective and the side effects are not severe. Participants who have a full response during treatment will take ruxolitinib for 56 more days, and then stop treatment. If ATL returns, they may restart treatment and continue it for as long as it is effective.

This phase I trial studies the side effects and best dose of monoclonal antibody therapy before stem cell transplant in treating patients with relapsed or refractory lymphoid malignancies. Radiolabeled monoclonal antibodies, such as yttrium-90 anti-CD45 monoclonal antibody BC8, can find cancer cells and carry cancer-killing substances to them without harming normal cells. When the healthy 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. Giving radiolabeled monoclonal antibody before a stem cell transplant may be an effective treatment for relapsed or refractory lymphoid malignancies.

This phase I/II clinical trial is studying the side effects and best dose of gamma-secretase inhibitor RO4929097 and to see how well it works in treating young patients with relapsed or refractory solid tumors, CNS tumors, lymphoma, or T-cell leukemia. Gamma-secretase inhibitor RO4929097 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

RATIONALE: Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing. Giving vorinostat together with lenalidomide may kill more cancer cells. PURPOSE: This phase I trial is studying the side effects and best dose of vorinostat when given together with lenalidomide in treating patients with relapsed or refractory Hodgkin lymphoma or non-Hodgkin lymphoma.

This phase II trial studies how well giving lenalidomide with or without rituximab works in treating patients with progressive or relapsed chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), prolymphocytic leukemia (PLL), or non-Hodgkin lymphoma (NHL). Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop cancer cells from growing. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving lenalidomide together with or without rituximab may kill more cancer cells.

This study will assess the safety, efficacy and pharmacokinetics of oral LBH589 in Japanese adult patients with refractory cutaneous T-Cell Lymphoma and adult T-cell leukemia/lymphoma. LBH589 is administered orally once a day for three days per week.

Drugs used in chemotherapy such as gemcitabine use different ways to stop cancer cells from dividing so they stop growing or die. Oblimersen may increase the effectiveness of gemcitabine by making cancer cells more sensitive to the drug. This phase I trial is studying the side effects and best dose of oblimersen and gemcitabine in treating patients with metastatic or unresectable solid tumors or lymphoma

This phase II trial studies how well nivolumab works in treating patients with peripheral T-cell lymphoma that has come back after a period of improvement or that does not respond to treatment. Monoclonal antibodies, such as nivolumab, may block cancer growth in different ways by targeting certain cells.

A Phase I, Multicenter study to evaluate the safety, tolerability, and Efficacy of LCAR-T2C CAR-T cells in relapsed or refractory CD4+T Lymphocyte Tumor Patients.

The purpose of this study is to: assess the effectiveness of lenalidomide for the treatment of patients with relapsed and or refractory peripheral T-cell lymphomas; and, assess the safety of lenalidomide. There are reports suggesting a therapeutic benefit of thalidomide in patients with refractory and/or relapsed Non-Hodgkin's Lymphoma's (NHL) which have led to the formal investigation of lenalidomide in the treatment of relapsed NHL's.
