Active clinical trials for "Leukemia, Hairy Cell"

The purpose of this study is to find out what effects, good and/or bad, treatment with vemurafenib (also known as Zelboraf™) has on the patient and on leukemia. Specifically, the researchers want to know how well vemurafenib eliminates leukemia from the blood.

This is a multi-center, open label, single arm, phase II trial of the oral BRAF inhibitor, vemurafenib, plus obinutuzumab in patients with previously untreated HCL. A Simon mini-max two-stage design will be employed to assess the efficacy of the combination treatment of vemurafenib and obinutuzumab. In the first stage of the protocol, 9 patients will be treated. If fewer than 6 CRs are seen among the first 9 patients, the study will be closed for lack of efficacy. If at least 7 patients respond to the treatment, then an additional 19 patients will be accrued to the second stage, for a total of 28 patients. Eligible patients will receive vemurafenib at a dose of 960mg orally twice daily (b.i.d.) continuously in cycles of 4 weeks (28 days) for a total of 4 cycles. Obinutuzumab will be administered concomitantly with vemurafenib starting at cycle 2 of treatment in cycles of 4 weeks. Obinutuzumab infusions will be administered at 1000mg per day on days 1, 8 and 15 during the cycle 2 and 1000mg per day every 4 weeks during the cycle 3 and 4 of treatment. After the completion of the treatment (i.e. after 4 cycles), a bone marrow aspirate and biopsy will be performed for assessment of response and evaluation of minimal residual disease (MRD). In case of certain defined toxicities, dose reductions of vemurafenib by 50% (480mg b.i.d.) or interruptions of up to 15 days are permitted. If additional dose reduction is required, vemurafenib may be reduced to 240mg oral b.i.d.

This phase I/Ib trial investigates the side effects of CC-486 and how well it works in combination with lenalidomide and obinutuzumab in treating patients with CD20 positive B-cell lymphoma that has come back (recurrent) or has not responded to treatment (refractory). Chemotherapy drugs, such as CC-486, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Lenalidomide is a drug that alters the immune system and may also interfere with the development of tiny blood vessels that help support tumor growth. Therefore, in theory, it may reduce or prevent the growth of cancer cells. Obinutuzumab is a type of antibody therapy that targets and attaches to the CD20 proteins found on follicular lymphoma cells as well as some healthy blood cells. Once attached to the CD20 protein the obinutuzumab is thought to work in different ways, including by helping the immune system destroy the cancer cells and by destroying the cancer cells directly. Giving CC-486 with lenalidomide and obinutuzumab may improve response rates, quality, and duration, and minimize adverse events in patients with B-cell lymphoma.

This phase I trial studies the best dose and side effects of flotetuzumab for the treatment of patients with blood cancers (hematological malignancies) that have spread to other places in the body (advanced) and have come back after a period of improvement (relapsed) or does not respond to treatment (refractory). Flotetuzumab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread.

This study is evaluating the safety, pharmacodynamics (PD), and efficacy of acalabrutinib and pembrolizumab in hematologic malignancies.

This phase I trial studies the side effects and best dose of genetically modified T-cells following peripheral blood stem cell transplant in treating patients with recurrent or high-risk non-Hodgkin lymphoma. Giving chemotherapy before a stem cell transplant helps stop the growth of cancer 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. 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. Giving an infusion of the donor's T cells (donor lymphocyte infusion) later may help the patient's immune system see any remaining cancer cells as not belonging in the patient's body and destroy them (called graft-versus-tumor effect)

This phase II trial studies how well ibrutinib works in treating patients with hairy cell leukemia that has returned after a period of improvement. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Background: About 80% of patients with hairy cell leukemia (HCL) have tumor cells that have a protein on their surface called cluster of differentiation 25 (CD25). The experimental drug LMB-2 is a recombinant immunotoxin that has been shown to kill leukemia and lymphoma cells with the CD25 protein. (A recombinant immunotoxin is a genetically engineered drug that has two parts - a protein that binds or targets a cancer cell, and a toxin that kills the cancer cell to which it binds.) Objectives: To evaluate the safety and effectiveness of LMB-2 in patients with HCL whose cancer cells contain the CD25 protein. To evaluate the effects of LMB-2 on the immune system, determine how the drug is metabolized by the body and examine its side effects. Eligibility: -Adults with hairy cell leukemia whose tumor cells have CD25 on their surface Design: Up to 27 patients may be included in the study. Patients receive an infusion of LMB-2 through a vein every other day for three doses (days 1, 3, 5), constituting one treatment cycle. Patients may receive up to six treatment cycles every 4 weeks unless their cancer worsens or they develop unacceptable side effects. Blood is drawn weekly for various tests. Before each cycle and in follow-up visits, disease status is evaluated with a physical examination, blood tests, chest x-ray and electrocardiogram. Before the first cycle, patients may have a computed tomography (CT) scan, echocardiogram (heart ultrasound test) and bone marrow biopsy. With the patient's permission, these tests may be repeated before other cycles also.

This phase I trial studies the side effects and best dose of cellular immunotherapy following chemotherapy in treating patients with non-Hodgkin lymphomas, chronic lymphocytic leukemia, or B-cell prolymphocytic leukemia that has come back. Placing a modified gene into white blood cells may help the body build an immune response to kill cancer cells.

This phase I/II trial studies the side effects and best dose of lenalidomide when given together with combination chemotherapy and to see how well they work in treating patients with v-myc myelocytomatosis viral oncogene homolog (avian) (MYC)-associated B-cell lymphomas. Lenalidomide may stop the growth of B-cell lymphomas by blocking the growth of new blood vessels necessary for cancer growth and by blocking some of the enzymes needed for cell growth. Biological therapies, such as lenalidomide, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop cancer cells from growing. Drugs used in chemotherapy, such as etoposide, prednisone, vincristine sulfate, doxorubicin hydrochloride, cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as rituximab, may block cancer growth in different ways by targeting certain cells. Giving lenalidomide together with combination chemotherapy may be an effective treatment in patients with B-cell lymphoma.
