Filter by:This study is characterizing the pharmacokinetics of vincristine using two different cohorts of patients. The first cohort includes patients with acute lymphoblastic leukemia (ALL) that are Bcr-Abl positive. This cohort of patients will receive vincristine along with imatinib in the induction chemotherapy regimen. The second cohort includes patients with ALL that are Bcr-Abl negative. This cohort of patients will receive vincristine without imatinib in the induction chemotherapy regimen. This study involves blood draws beginning on day 7 of the treatment protocol and these samples will be analyzed for pharmacokinetic parameters. Imatinib and vincristine are both metabolized by the hepatic CYP 450 enzyme system. Imatinib is an inhibitor of the system and co-administration of imatinib and vincristine has the potential to increase the blood level of vincristine. This could explain the increased level of neurotoxicity that is currently being seen with the co-administration of these two agents in the treatment of Bcr-Abl positive ALL.
RATIONALE: Studying samples of DNA in the laboratory from patients who received fludarabine-based treatment may help doctors learn more about the effects of fludarabine on cells. It may also help doctors understand how well patients respond to treatment. PURPOSE: This research study is studying DNA samples from patients with chronic lymphocytic leukemia previously treated with fludarabine-based therapy.
Background: - Ofatumumab was approved by the U.S. Food and Drug Administration to treat patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) who have not responded to standard chemotherapy. Ofatumumab is a substance that recognizes specific types of white blood cells called B-lymphocytes, which become cancerous in CLL/SLL. Ofatumumab attaches to a molecule called CD20, which is found on the surface of B-cells, and destroys them. Previous studies have shown that ofatumumab can decrease the number of B-cells in patients with CLL/SLL who have been treated with chemotherapy, but more research is needed to determine it if can also be used to treat patients with previously untreated CLL/SLL. Objectives: - To determine a safe and effective dose of ofatumumab, along with chemotherapy, to treat chronic lymphocytic leukemia or small lymphocytic lymphoma. Eligibility: - Individuals at least 18 years of age who have been diagnosed with CLL or SLL that has not been treated with chemotherapy. Design: - Eligible participants will be screened with a physical exam, blood samples, lymph node and bone marrow biopsies, and imaging studies. - Participants will be separated into 2 groups: all participants will receive ofatumumab and fludarabine, and some participants will be selected to also receive cyclophosphamide (based on results of certain blood tests). - Participants will receive the study drugs (ofatumumab and fludarabine, and optional cyclophosphamide) by infusion for a maximum of 6 days, followed by 21 days off drug. - Participants will have 6 cycles of treatment according to a schedule set by the study doctors, and may have their dose levels adjusted if side effects develop. - Participants who have disease remaining after 6 cycles will receive additional ofatumumab every 2 months, starting 2 months after the end of the 6th cycle and continuing for a total of 4 doses, before entering the follow-up phase of the trial. Participants who do not have residual disease after 6 cycles will not receive additional therapy, and will immediately enter the follow-up phase of the trial. - Participants will have a follow-up exam every 2 to 4 months for 2 years after the end of treatment, and then as required by the study doctors for as long as the study remains open. These visits will involve a full medical exam, blood samples, lymph node and bone marrow biopsies, and imaging studies.
The purpose of this study is to measure, in pilot/observational study, panels of circulating proteins in real time at the onset of neutropenic fever/infection in patients with acute or chronic leukemias undergoing chemotherapy or other biologic treatment. And to generate preliminary trend results in panels of circulating proteins longitudinally during the period of neutropenia and to correlate those values to clinical/laboratory data and patient outcomes.
A Study of Bafetinib as Treatment for Patients with Relapsed or Refractory B-Cell Chronic Lymphocytic Leukemia (B-CLL).
This research trial studies a risk-based classification system for patients with newly diagnosed acute lymphoblastic leukemia. Gathering health information about patients with acute lymphoblastic leukemia may help doctors learn more about the disease and plan the best treatment.
This phase I clinical trial is studies the side effects and best dose of giving veliparib together with temozolomide in treating patients with acute leukemia. Veliparib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving veliparib together with temozolomide may kill more cancer cells.
This study is to test escalating doses of carfilzomib in patients with relapsed acute myeloid and acute lymphoblastic leukemia.
The goal of this clinical research study is to learn if CMC-544 given alone, and possibly given in combination with rituximab, can help to control the disease in patients with ALL. The safety of the study drug(s) will also be studied.
This is a phase II, non-randomized, single institution study in symptomatic, previously untreated CLL patients. All patients will receive the study drug, lenalidomide, given PO daily continuously on a 28 day cycle at the starting dose level of either 2.5 mgs or 5 mgs with dose escalations to a target dose of 25mg daily. Oral dexamethasone at 12 mg PO daily will be administered on days 1-7, 14 and 21 of each cycle. Patients will be treated with lenalidomide and dexamethasone to 2 cycles past CR or to a maximum of 18 cycles, each cycle of 28 days duration. Primary endpoint is response.
