View clinical trials related to Hairy Cell Leukemia.
Filter by:Background: Hairy cell leukemia (HCL) is a rare, slow-growing blood cancer in which the bone marrow makes too many of certain white blood cells. The antibody Rituximab/Ruxience binds to a protein in cancerous white blood cells and is often used to treat HCL. Researchers want to see if combining it with the drug Moxetumomab pasudotox-tdfk (also called Lumoxiti) can fight HCL better. Objective: To test the safety of Moxetumomab pasudotox taken with Rituximab/Ruxience for people with HCL or HCL variant. Eligibility: People age 18 years and older with HCL or HCL variant that has not responded to standard therapy Design: Participants will be screened with: Medical history Physical exam Blood, heart, and urine tests Test of blood oxygen levels Review of bone marrow. This can be from previous test results or a new sample. Scans Exercise test Participants will get the study drugs in up to 8 cycles. A cycle will last about 28 days. The study drugs will be given through a plastic tube in a vein. In the first week of cycle 1, participants will have: 1 visit to get Rituximab or Ruxience for 7.5 hours 3 visits to get Lumoxiti for 30 minutes per infusion In the first week of cycles 2-8, participants will have: 1. visit to get Rituximab/Ruxience for 2-4 hours and Lumoxiti for 30 minutes 2. visits to get Lumoxiti for 30 minutes per infusion Participants will be asked to drink lots of water and take aspirin during the cycles. They will get drugs to minimize allergic reactions. Participants will repeat screening tests at visits throughout the cycles and 1 follow-up visit. They may have an eye exam. ...
This phase II trial studies how well flotetuzumab works in treating patients with CD123 positive blood cancer that has come back or does not respond to treatment. Immunotherapy with monoclonal antibodies, such as flotetuzumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
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/II trial studies the side effect and best dose of entospletinib when giving together with obinutuzumab and to see how well they work in treating patients with chronic lymphocytic leukemia, small lymphocytic lymphoma, or non-Hodgkin lymphoma that has come back. Entospletinib may stop the growth of cancer cells by blocking some of the enzymes need for cell growth. Monoclonal antibodies, such as obinutuzumab, may interfere with the ability of cancer cells to grow and spread. Giving entospletinib and obinutuzumab together may work better in treating patients with chronic lymphocytic leukemia, small lymphocytic lymphoma, or non-Hodgkin lymphoma.
Hairy-cell leukemia is a rare and indolent lymphoid disorder, representing 2% of all cases of lymphoid leukemias. Treatment of hairy-cell leukemia relies mainly on the purine analogs, cladribine and pentostatin, which have shown similar efficacy and constitute the gold standard of care either as front-line therapy or for relapsed patients. However, despite the remarkable response rates obtained with purine analogs therapy, some patients will eventually relapse and the efficacy of these agents seems to decrease at each line of treatment. The addition of new molecules to purine analogs may improve the response rates and prevent relapse. Rituximab is a chimeric IgG1 kappa-type monoclonal antibody directed against the CD20 molecule. It was first used in relapsed patients with hairy-cell leukemia more than 10 years ago and several series of patients treated with rituximab as monotherapy were published in the following decade, reporting response rates ranging from 25% to 80%.
This study is evaluating the safety, pharmacodynamics (PD), and efficacy of acalabrutinib and pembrolizumab in hematologic malignancies.
The trial will test the effectiveness and toxicity of subcutaneous treatment with one cycle of cladribine in patients with hairy cell leukemia requiring treatment. They have to be untreated so far or may be pretreated with alpha-interferon.
The study objective is to evaluate the safety, pharmacokinetics (PK), and pharmacodynamics (PD) of orally administered PLX8394 in patients with advanced solid tumors. An additional objective is to identify a Recommended Phase 2 (RP2D) for further evaluation in the Extension Cohorts (Phase IIa portion). The study objective of the Extension Cohorts (PART 2 portion) is to assess the objective tumor response and the PK, PD, and safety of PLX8394 when the RP2D is used in patients with advanced BRAF-mutated cancers.
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.
The presence of a specific mutation in the gene known as B-RAF has been found in patients who have Hairy Cell Leukemia. In this study this specific mutation known as V600E will be ascertained in peripheral blood samples of patients who have this disease and in a group of patients who have a similar chronic lymphoproliferative conditions such as splenic marginal lymphoma. The finding of this specific mutation will help to verify or exclude the diagnosis of Hairy Cell Leukemia and determine whether patients are in remission.
