Filter by:This is a multicenter phase I clinical study evaluating the safety, tolerability, and efficacy of LCAR-T2C cell agents targeting CD4 in patients with relapsed/refractory CD4-positive T lymphocytic tumors. Thirty-three subjects will be enrolled. Subjects will be pretreated with chemotherapy prior to infusion of CAR T cells: about 5 days before cells transfusion, the patients who planned to reinfuse CAR T cells were treated with fluorodarabine 30 mg/m2( body surface area) and cyclophosphamide 300 mg/m2( body surface area) for 3 days. hen this study will be using a 3+3 dose escalation approach from dose 1 (DL-1): 5×105 to dose 2 (dl-2): 1.5×106 , to dose 3 (dl-3): 5×106 to dose 4 (dl-4): 10.0×106. Below the lowest dose was reinfused at the PI's discretion.
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.
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.
This is a phase-II study to evaluate the efficacy of a salvage regimen in children with relapsed T-cell ALL or lymphoma. Peg-asparaginase, mitoxantrone, intrathecal triples (IT) (intrathecal methotrexate/hydrocortisone/cytarabine) (ITMHA) and dexamethasone are commonly used drugs to treat relapsed or refractory acute lymphocytic leukemia or lymphoma (ALL). In this study, the investigators want to know if adding three drugs called panobinostat, bortezomib and liposomal vincristine (VSLI) to this regimen will result in remission (no signs or symptoms of leukemia or lymphoma). - Panobinostat has been approved by the FDA for treating adults with multiple myeloma, but it has not been approved for use in children and has not been given together with the other drugs used in this study. It has not been widely studied in children. - VSLI has been approved by the FDA for adults with relapsed or refractory ALL, but has not yet been approved for treating children with leukemia or lymphoma. - Bortezomib has been approved by the FDA for treating adults with a cancer called multiple myeloma and adults with relapsed mantle cell lymphoma; it has not been approved for treating children. PRIMARY OBJECTIVE: - To estimate the complete remission (CR) rate for patients with T-cell lymphoblastic leukemia and lymphoma in first relapse. SECONDARY OBJECTIVES: - To evaluate minimal residual disease (MRD) levels at end of each block of therapy. - To describe the toxicities of vincristine sulfate liposome injection (VSLI) when used in combination with chemotherapy and bortezomib.
The purpose of this study is to evaluate how safe and effective the combination of two different drugs (brentuximab vedotin and rituximab) is in patients with certain types of lymphoma. This study is for patients who have a type of lymphoma that expresses a tumor marker called CD30 and/or a type that is associated with the Epstein-Barr virus (EBV-related lymphoma) and who have not yet received any treatment for their cancer, except for dose-reduction or discontinuation (stoppage) of medications used to prevent rejection of transplanted organs (for those patients who have undergone transplantation). This study is investigating the combination of brentuximab vedotin and rituximab as a first treatment for lymphoma patients
This pilot phase 1-2 trial studies the side effects and best of dose ipilimumab when given together with local radiation therapy and to see how well it works in treating patients with recurrent melanoma, non-Hodgkin lymphoma, colon, or rectal cancer. Monoclonal antibodies, such as ipilimumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Radiation therapy uses high energy x rays to kill cancer cells. Giving monoclonal antibody therapy together with radiation therapy may be an effective treatment for melanoma, non-Hodgkin lymphoma, colon, or rectal cancer. - The phase 1 component ("safety") of this study is ipilimumab 25 mg monotherapy. - The phase 2 component ("treatment-escalation") of this study is ipilimumab 25 mg plus radiation combination therapy.
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 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 clinical trial studies etoposide, filgrastim and plerixafor in improving stem cell mobilization in patients with non-Hodgkin lymphoma. Giving colony-stimulating factors, such as filgrastim, and plerixafor and etoposide together helps stem cells move from the patient's bone marrow to the blood so they can be collected and stored.
