Active clinical trials for "Leukemia"

There are no strategies developed post-stem cell transplant (SCT) for patients who receive allogenic SCT with a significant amount of blasts prior SCT. Novel strategies to treat relapsed AML/MDS and to reduce the incidence of relapse after allogeneic SCT are needed. This study is being done in patients with high-risk MDS or AML who undergo an allogeneic SCT. The study will have two arms, participants who receive an HLA-matched unrelated donor SCT (Arm A) or HLA- haploidentical SCT (Arm B). Following myeloablative conditioning (MAC), GVHD prophylaxis with post-transplantation cyclophosphamide (PTCy), tacrolimus and mycophenolate mofetil will be given per standard of care. At 40-60 days post SCT, If the patient has not had any evidence of Grade II-IV acute graft-versus-host-disease (aGVHD), Nivolumab will be given intravenously every 2 weeks for 4 cycles of consolidation or treatment with Nivolumab. Dose-escalation of Nivolumab will follow the standard 3+3 design where a maximum of three dose levels will be evaluated, with a maximum of 18 patients treated with nivolumab per arm. As the maximum tolerated dose (MTD) of Nivolumab may differ between Arm A and Arm B, dose escalation of nivolumab in each arm will be followed separately following allogeneic SCT. Immunosuppression with tacrolimus will be continued during the cycles of PD-1 blockade to provide a moderate level of GVHD prophylaxis during consolidation or treatment with nivolumab.

This phase 2 clinical trial investigates the effectiveness of cytokine-induced memory-like natural killer (CIML NK) cells in combination with FLAG chemotherapy as a treatment for refractory or relapsed AML. Previous studies in adults with AML sowed successful induction of remission and a previous phase 1 study demonstrated that CIML NK cells can be used safely in pediatric patients. This phase 2 study uses FLAG chemotherapy to lower leukemic burden and suppress the recipient's immune system to provide an optimal environment for CIML NK cell expansion and anti-leukemic activity.

This phase II trial studies how well enasidenib works in treating in patients with acute myeloid leukemia with an IDH2 gene mutation that has come back or has not responded to treatment. Enasidenib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. In this study we are investing if enasidenib can be used as maintenance therapy post salvage induction chemotherapy.

This phase II trial studies the effects of ibrutinib in treating patients with B-cell malignancies who are infected with COVID-19. Ibrutinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Ibrutinib is a first in class Bruton tyrosine kinase inhibitor (BTKi), for the treatment of B-cell malignancies. This study is being done to determine if taking ibrutinib after contracting COVID-19 will make symptoms better or worse.

GVHD remains a major cause of morbidity and mortality following SCT. The current standard of care for prophylaxis against GVHD includes tacrolimus and methotrexate. This study proposes to utilize acalabrutinib, a Bruton tyrosine kinase (BTK) inhibitor, for GVHD prophylaxis following allogeneic SCT. The hypothesis is that the addition of acalabrutinib to our institutional standard GVHD prophylaxis (tacrolimus and methotrexate) is safe, feasible, and effective in reducing both the incidence and severity of acute GVHD.

This is a first-in-human study to evaluate the feasibility, safety and preliminary antitumor efficacy of autologous chimeric antigen receptor (CAR) T cells targeting both CD19 and CD22, manufactured with T-Charge(TM) process. CAR-T cells will be investigated as single agent in pediatric and adult acute lymphoblastic leukemia (ALL).

The aim of the study is to test the safety and efficacy of BL-8040 (a CXCR4 antagonist) in improving the response to imatinib in CML patients not achieving an optimal response with imatinib alone.

This research study is for subjects that are receiving a bone marrow transplant. As part of the transplant subjects will receive stem cells from a donor who has agreed to donate stem cells for them. Unfortunately, it takes a long time for the immune system to recover after a bone marrow transplant. This makes it more likely for patients to develop serious infections. This study is being done to better understand how the immune system will recover after transplant. The immune system includes the cells that help fight infection. This study will help investigators understand which patients are at risk for developing infections after transplant. All children and adults receive standard vaccines (shots) during their lifetime to provide protection from many different infections. One such infection is tetanus, a bacteria that can cause life-threatening problems. After transplant patients no longer have protection from infections such as tetanus. Therefore, most patients need to receive all their vaccine (shots) again after transplant. This is usually done 1-2 years after transplant, since it may take that long for patients to have a normal immune system. However, the investigators believe that the time it will take for the patient to develop normal protection against tetanus can be shortened if both the patient and the patient's stem cell donor receive a tetanus vaccine. The goal of this study is to determine if giving a tetanus vaccine to the donor and the patient will provide the patient with enough protection (immunity) to prevent infection following bone marrow transplant.

The purpose of this study is to evaluate the effect of GS-1101 on the onset, magnitude, and duration of tumor control

To compare the efficacy and safety of combination treatment with Genasense, fludarabine, and rituximab versus combination treatment with fludarabine and rituximab in previously untreated subjects with CLL.
