Active clinical trials for "Leukemia"

This study explores the effect of zoledronic acid on incident vertebral fractures and osteonecrotic lesions in children recently diagnosed with acute lymphoblastic leukemia.

The purpose of the study is to investigate whether the combination of obinutuzumab and ibrutinib (administered up to 840 mg per day) might be useful for the treatment of CLL or SLL that is not responding or no longer responding to treatment with ibrutinib alone. The study will evaluate whether this regimen can reduce the amount of cancerous cells in the body. Subjects will be treated with ibrutinib at a dose of up to 840 mg a day by mouth, as well as obinutuzumab infusions. Although both of these agents are approved by the FDA for the treatment of CLL or SLL, the combination and the dosing schedule of ibrutinib are considered experimental.

The stud will evaluate whether infusions of CD45RA-depleted lymphocytes from the donor early post-transplant is a safe way to improve immunity to common infections in recipients of TCR-alpha/beta depleted hematopoietic stem cell grafts.

This study is designed in its first part (phase Ib) to determine the recommended dose of the OTX015 + Vidaza (azacitidine) combination in newly diagnosed acute myeloid leukemia patients not candidate for standard intensive induction therapy. It will be followed by a randomized phase II part to assess the efficacy of the combination using 2 arms : Vidaza (azacitidine) alone vs. OTX015 in combination with Vidaza (azacitidine).

Acute Graft-versus-Host-Disease (GVHD) is an important cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT). This study aims to determine if any of three new GVHD prophylaxis approaches improves the rate of GVHD and relapse free survival at one year after transplant compared to the current standard prophylaxis regimen.

Despite improvements in outcomes after Hematopoietic Cell Transplantation (HCT) for Acute Myeloid Leukemia (AML) and Myelodysplastic Syndrome (MDS), the risk of relapse remains high and is the most common cause of mortality after HCT. Moreover, treatment options for relapse after HCT are limited. Strategies to reduce relapse with maintenance therapy in patients who are at high risk are needed to improve survival. 5-aza is a hypomethylating agent that has shown immune modulating properties that may enhance the graft-versus-leukemia (GVL) effect, including upregulation of tumor-associated antigen and costimulatory molecule expression. Moreover, 5-aza has properties that suggest protection against graft-versus-host disease (GVHD) as well. Preliminary data shows that it is well tolerated and effective in clinical use for the treatment of AML or MDS relapse after HCT, as well as for maintenance therapy. This study will evaluate the use of 5-aza for maintenance after HCT in patients with AML or MDS with risk factors that are associated with a high risk for relapse.

Gene transfer is a process in which the DNA (genetic material) of certain cells is changed. In this study, gene transfer will be performed on a type of white blood cell (called T cells) to recognize leukemia cells in the same person the T cells were collected from. The goal of this clinical research study is to learn if it is safe to give these genetically-changed T cells back to patients with CLL/SLL. Researchers also want to learn if these cells can help to attack CLL/SLL cells.

In an attempt to reduce relapse risk and improve outcomes following haploidentical transplantation for patients with high risk hematologic malignancies, the investigators will implement several strategies to augment the well documented effect of NK cell alloreactivity seen in HLA-mismatched transplantation. These strategies include (1) choosing potential haploidentical donors for optimal NK-alloreactivity, (2) utilizing proteasome inhibition post-transplant with MLN9708 to both sensitize tumor cells to NK cytotoxicity and protect against graft-versus-host disease (GVHD), and (3) eliminating mycophenolate mofetil from the post-transplant immunosuppression regimen to improve NK cell reconstitution following haploidentical peripheral blood stem cell transplantation.

The goal of Part 1 of this clinical research study is to learn if ponatinib alone can help to control FLT3-mutated AML or FLT3-mutated high-risk MDS. The safety of this drug will also be studied. The goal of Part 2 of this clinical research study is to find the highest tolerable dose of ponatinib in combination with 5-azacytidine and to learn if the highest dose level found can help to control FLT3-mutated AML or FLT3-mutated high-risk MDS. The safety of this combination will also be studied.

The purpose of this study is to find out whether adding a new drug, dasatinib, to imatinib is safe, and whether the combination of the two drugs will help decrease the number of cells that contain the Philadelphia chromosome.
