Filter by:This is a non-randomized clinical trial to evaluate the safety and efficacy of CD22CART administered after lymphodepleting chemotherapy in adults with relapsed / refractory B Cell Lymphomas. All evaluable participants will be followed for overall survival (OS), progression free survival (PFS), and duration of response (DOR). An evaluable participant is one who completes leukapheresis, lymphodepleting chemotherapy and CART infusion.
The current standard-of-care for Hairy Cell Leukemia involves chemotherapy, with agents such as cladribine or pentostatin. Chemotherapy is associated with infection, low blood counts and predisposition to future cancers. This study tests a new yet previously validated drug combination for the treatment of hairy cell leukemia. The treatment involves 8 weeks of treatment with an oral drug called vemurafenib and 8 doses of an intravenous medication called rituximab. The goal of this study is to see whether this treatment is better tolerated and more effective than the currently used treatment in this disease. In addition, this study uses a lower dose of vemurafenib than previous studies have used, with the goal of minimizing side effects from this medication.
Lymphoid chronic B-cell malignancies are frequent pathologies that affect adults, with a very variable prognosis and treatment (some of them can remain untreated). The diagnosis of these malignancies relies on the study of the morphology of tumoral cells and the expression by these cells of several markers, mainly via a technical approach called flow cytometry. Because the markers currently used remain imperfect, additional ones are needed for an accurate diagnosis that affect both prognosis and treatment. In addition, because numerous markers are used at the diagnosis, there is a need of tools that synthetize the multi-dimensional structure of the data obtained. The primary purpose of this study is to detect new markers that can be of help for the diagnosis of Marginal Zone Lymphoma and other B-cell chronic lymphoid malignancies. The secondary purpose of this study is to obtain a statistical algorithm that allow a good prediction of the different sub-types of chronic B-cell malignancies mainly using the results of flow cytometry.
Background: CAR (Chimeric Antigen Receptor) T cell therapy is a type of cancer treatment in which a person s T cells (a type of immune cell) are changed in a laboratory to recognize and attack cancer cells. Researchers want to see if this treatment can help people with hairy cell leukemia (HCL). Objective: To test whether it is safe to give anti-CD22 CAR T cells to people with HCL. Eligibility: Adults ages 18 and older with HCL (classic or variant type) who have already had, are unable to receive, or have refused other standard treatments for their cancer. Design: Participants will be screened with the following: Medical history Physical exam Blood and urine tests Biopsy sample Electrocardiogram Echocardiogram Lung function tests Imaging scans Some screening tests will be repeated during the study. Participants may need to have a catheter placed in a large vein. Participants will have magnetic resonance imaging of the brain. Participants will have a neurologic evaluation and fill out questionnaires. Participants will have leukapheresis. Blood will be removed from the participant. A machine will divide whole blood into red cells, plasma, and lymphocytes. The lymphocytes will be collected. The remaining blood will be returned to the participant. Participants will get infusions of chemotherapy drugs. Participants will get an infusion of the anti-CD22 CAR T cells. They will stay at the hospital for 14 days. Then they will have visits twice a week for 1 month. After treatment, participants will be followed closely for 6 months, and then less frequently for at least 5 years. Then they will have long-term follow-up for 15 years.
This is a phase I, multi-center, open-label, dose-escalation study to evaluate the safety, tolerability, pharmacokinetics and clinical activity of LP-168 in subjects with relapsed or refractory B-cell malignancies. LP-168 is a small molecule inhibitor.
Background: Hairy cell leukemia (HCL) does not usually respond to chemotherapy. Most people with HCL have a BRAF gene mutation. This can increase the growth of cancer cells. Vemurafenib has been tested to treat these people. However, researchers think a combination of drugs might work better. Objective: To test if treatment with a combination of encorafenib and binimetinib in BRAF mutant HCL is more effective than treatment with vemurafenib. Eligibility: People ages 18 and older with BRAF mutant HCL that did not respond to or came back after treatment Design: Participants will be screened with: Medical history Physical exam Bone marrow biopsy: A needle will be injected through the participant s skin and into a bone to remove liquid. Blood and urine tests Heart and lung function tests CT or MRI scan: Participants will lie in a machine that takes pictures of the body. They may have a contrast agent injected into a vein. Eye exam Participants will take the study drugs by mouth in 28-day cycles. They will take encorafenib daily. They will take binimetinib twice daily. They will keep a pill diary. Participants will take their temperature daily. Participants will have at least 1 visit before each cycle. Visits will include repeats of some screening tests. They will also include abdominal ultrasounds, exercise stress tests, and skin evaluations. Participants may continue treatment as long as their disease does not get worse and they do not have bad side effects. About a month after their last dose of treatment, participants will have a follow-up visit. Then they will have annual follow-ups....
Background: Most people with hairy cell leukemia have a BRAF gene mutation. They can be treated with BRAF inhibitors, drugs that target this mutation. For people who do not have this mutation, BRAF inhibitors are not a treatment option. We found that in hairy cell leukemia, when BRAF is not mutated, the MEK gene frequently is. Binimetinib is a MEK inhibitor which targets MEK. It is important to determine if this drug can be a good treatment option in those who cannot benefit treatment with BRAF inhibitors. Objective: To see if binimetinib is an effective treatment for hairy cell leukemia that does not have a BRAF mutation. Eligibility: People ages 18 and older with hairy cell leukemia without a mutation in the BRAF gene and whose disease either did not respond to treatment or came back after treatment Design: Participants will be screened with: - Medical history - Physical exam - Blood and urine tests - Lung and heart tests - Eye exam - Bone marrow biopsy: A needle will be injected through the participant s skin into the bone to remove a sample of marrow. - CT or MRI scan: Participants will lie in a machine that takes pictures of the body. They might receive a contrast agent by vein. Before they start treatment, participants will have an abdominal ultrasound, pulmonary function tests, and exercise stress tests. Participants will take binimetinib by mouth twice daily in 28-day cycles. They will keep a medication diary. Participants will have at least one visit before every cycle. Visits will include repeats of some screening tests. Participants may continue treatment as long as their disease does not get worse and they do not have bad side effects. About a month after their last dose of treatment, participants will have a follow-up visit. They will then have visits once a year. ...
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.
RATIONALE: The CAT-8015 immunotoxin can bind tumor cells and kill them without harming normal cells. This may be an effective treatment for hairy cell leukemia(HCL) that has not responded to chemotherapy, surgery or radiation therapy. PURPOSE: Phase I dose escalation study to determine the maximum tolerated dose of CAT-8015 immunotoxin in treating patients who have hairy cell leukemia (HCL) that has not responded to treatment.
This phase II trial studies the side effects and how well cladribine and rituximab work in treating patients with hairy cell leukemia. Drugs used in chemotherapy, such as cladribine, 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. Immunotherapy with monoclonal antibodies, such as rituximab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cladribine together with rituximab may kill more cancer cells.
