Filter by:This clinical trial studies the side effects of gemtuzumab ozogamicin and how well it works in treating patients with acute myeloid leukemia. Monoclonal antibodies, such as gemtuzumab ozogamicin, can block cancer growth in different ways. Some block the ability of cancer to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them
This is a study to evaluate PF-04449913 (an inhibitor of the Hedgehog pathway) in Acute Myeloid Leukemia and high-risk Myelodysplastic Syndrome in combination with standard agents used to treat these diseases.
The goal of this clinical research study is to learn if the combination of azacitidine and GM-CSF can help to control MDS. The safety of these drugs will also be studied. Azacitidine is designed to block certain proteins that stop the function of tumor-fighting genes. By blocking the "bad" proteins, the tumor-fighting genes may be able to work better. Granulocyte-macrophage colony-stimulating factor (GM-CSF) is designed to help produce white blood cells. This may help to fight infections.
MicroRNAs are small molecules which have recently been discovered in cells. They are known to be responsible for the normal development of cells and when they are disrupted can contribute to the development of cancer. Many previous studies have been done evaluating the expression of microRNAs in normal tissues as well as a wide variety of cancers. Recently, microRNAs from tumor cells have been detected circulating in the blood of patients with cancer. This presents a novel opportunity to use microRNAs in the blood as an early predictor of cancer as well as a marker of response to therapy. No previous studies have been performed evaluating microRNAs in the blood or cerebrospinal fluid of patients with childhood cancers. We propose a feasibility study to evaluate the presence of microRNAs in the blood and cerebrospinal fluid of patients with central nervous system tumors, leukemia and lymphoma who are currently on chemotherapy and undergoing blood draws, lumbar punctures and/or reservoir taps for routine clinical care. If we're able to identify circulating microRNAs in this population of pediatric patients, we will build upon this data in proposing a future study.
Patients included in the study with high risk acute myeloid leukemia or myelodysplastic syndrome as defined will receive an allogeneic transplantation conditioned by either myeloablative or reduced regimen. Following allogeneic transplantation, patients will receive a maintenance regimen combining chemotherapy with azacitidine (aza) and immunotherapy with donor lymphocyte infusion.
Trial protocol intended the optimization of induction treatment with: 1. Inclusion of PEG-ASP in induction and in the three blocks of consolidation. 2. Reduction of the dose of daunorubicin, and recent studies have shown that the use of high doses of anthracyclines has not brought higher response rates or longer duration 3. Replacing the poor cytological response at day 14 by the level of ER at the end of induction as a criterion to decide the further treatment (consolidation or second induction), so as to have only one criterion (the ER) throughout the study to decision making. For another hand, reducing non-essential drugs consolidation blocks to try to reduce toxicity during it, and replace the ASP E. coli in induction and consolidation of PEG-ASP to ensure a more sustained asparagine depletion. Also, increasing the dose of methotrexate (3 to 5 g/m2) in patients with ALL-T, since there is recent evidence of a higher response rate with this strategy. Performing an allo-HSCT early (after one cycle of consolidation) for patients with inadequate level of ER after two cycles of induction or in those patients who required two courses of induction and have obtained proper ER after the second. Conducting studies of RD centrally by cytofluorometry following Euroflow consensus standards, to avoid bias in making treatment decisions
This clinical trial is studying biomarkers as a diagnostic tool in samples from younger patients with B-cell acute lymphoblastic leukemia. Finding specific biomarkers may help improve the treatment of patients with B-cell acute lymphoblastic leukemia
This Phase 3, randomized, double-blind, placebo-controlled study is to evaluate the effect of idelalisib in combination with rituximab on the onset, magnitude, and duration of tumor control in participants previously treated for chronic lymphocytic leukemia (CLL). Eligible patients will be randomized with a 1:1 ratio into 1 of the 2 treatment arms to receive either idelalisib plus rituximab or placebo plus rituximab. Participants who are tolerating primary study therapy but experience definitive CLL progression are eligible to receive active idelalisib therapy in the extension study, GS-US-312-0117.
The primary objective of this extension study (GS-US-312-0117) that is a companion study to Study GS-US-312-0116 (NCT01539512), is to evaluate the effect of idelalisib on the onset, magnitude, and duration of tumor control. Randomization was done in study GS-US-312-0116, and carried forward to study GS-US-312-117.
The purpose of this study is to investigate if a type of magnetic resonance imaging (MRI) scan of the bone marrow before the start of standard chemotherapy can predict complete remission of leukemia patients after the therapy. This type of MRI scan, called dynamic contrast-enhanced MRI (DCE-MRI), measures bone marrow blood flow. For those patients who do not achieve complete remission status after initial therapy and will be treated with additional therapy, the investigators are also interested in determining if the second MRI exam before the additional therapy can predict complete remission. If successfully tested, the MRI exam may be used in the future to help with early identification of patients who are unlikely to respond to standard chemotherapy. This will allow for a personalized therapeutic plan to be developed for these patients at an early stage and prevent them from being exposed to toxic and ineffective therapies.
