Filter by: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.
Acute leukemias are commonly seen in elderly and have no effective therapy. In recent years, small molecule inhibitors have shown a tremendous promise in cancer treatment such as chronic myeloid leukemia and lung cancer. Thus, in this proposal, we intend to use our novel patented "indole" compound to conjugated with hydroxamic acid in histone deacetylases inhibitor, suberoylanilide hydroxamic acid and further modify its structure to generate novel small-molecule anticancer compounds. By screening acute leukemic cell lines, we will look for compounds that have shown potential for future drug development. In our preliminary studies, we have identified a novel compound, MPT0E001, to have marked growth inhibitory activity, induce apoptosis and downregulate c-Myc protein level. We intend to use MPT0E001 as a basis to develop novel compounds and test them in multiple leukemic cell lines and primary leukemia samples (Specific aim 1) and identify the mechanisms for downregulation of c-Myc and other pathways such as NF-kappaB and Akt (Specific aim 2). Once we have identified the lead compounds, we will use murine model to assess the acute toxicity profiles in different dose ranges and examine the effects of blood counts and vital organs. After toxicity study, we will test the lead compounds using in vivo xenogenic murine model using both cell lines and primary leukemia. Using this approach, we hope to develop novel compounds that are able to be used in future leukemic therapy.
The investigators are interested in identifying patient-specific factors related to donor chimerism in patients who receive nonmyeloablative hematopoietic stem cell transplants from haploidentical donors. We will look how patients' bodies break down and immediately respond to cyclophosphamide, fludarabine and mycophenolate mofetil.
This phase I/II trial is studying the side effects and best dose of bendamustine hydrochloride when given together with idarubicin in treating older patients with previously untreated acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). Drugs used in chemotherapy, such as bendamustine hydrochloride or idarubicin, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells
FLT3 overexpression in acute myeloid leukemia (AML) is often caused by mutations in this gene. These mutations cause constitutive phosphorylation of FLT3 proteins leading to increased proliferation and survival, decreased apoptosis and resistance to chemotherapeutic agents in AML cells. There are two major types of FLT3 mutations- internal tandem duplication (ITD) and point mutation at 835th amino residue. AMLs with FLT3 mutations have worse prognosis and are often resistant to conventional chemotherapy. Several small molecule compounds targeting FLT3 have been in the market or in clinical trials. Therefore, identification of these mutations at the time of diagnosis will provide a better prognostic prediction, might guide the treatment selection and follow-up strategies. In this study, the investigators will develop a sensitive molecular assay to detect FLT3 mutations for future clinical application. The investigators will collect 100 AML samples with at least 20 samples with known FLT3 mutations. The investigators will compare this assay with commonly used methods and standardize the procedure to meet the requirement of clinical pathology laboratory with reasonable cost.
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.
RATIONALE: Studying samples of blood or tumor tissue from patients with cancer in the laboratory may help doctors learn about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is studying biomarker changes in samples from young patients with acute myeloid leukemia.
