Active clinical trials for "Hematologic Neoplasms"

This research study uses a drug called cyclophosphamide to decrease the incidence of GVHD in matched sibling hematopoietic stem cell transplant. In doing so, the goal of the study is to increase overall survival.

Allogeneic stem cell transplantation offers the hope of cure for a wide variety of hematologic malignancies. Mature donor T-cells play a critical role in the success or failure of this procedure and a subset of donor T-cells mediate graft-versus-host disease while other subsets provide the foundation for immune recovery. The major challenge in allogeneic stem cell transplantation is determining how to maximally exploit the beneficial effects mediated by T-cells without causing GvHD. This challenge could be overcome by selectively depleting the population of donor T-cells responsible for eliciting the GvHD response. The study hypothesis is depletion of naïve T-cells from the donor lymphocyte inoculum will not cause GVHD while providing T-cells to affect both anti-infection and anti-tumor responses.

The goal of our study will be to determine the clinical and biological safety of infusing immuno-selected NK (Natural Killer) CD3-/CD56+ cells, early after allogeneic transplantation with colony stimulating factor (G-CSF) mobilized peripheral blood stem cells and Reduced Intensity Conditioning (RIC), as a potential substitute to usual "Donor Lymphocyte Infusion" (DLI), that contain the whole range of immune effectors. The trial will include several progressive steps: dose escalation up to a level compatible with the cost-effectiveness potential of the device and clinical situation and recombinant interleukin-2 (r-IL2) activation of selected NK cells in vitro prior to re-infusion.

This phase I/Ib trial studies the side effects and best dose of ipilimumab or nivolumab in treating patients with cancers of the blood and blood-forming tissues (hematologic cancers) that have returned after a period of improvement (relapsed) after donor stem cell transplant. Immunotherapy with monoclonal antibodies, such as ipilimumab and nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Patients with a hematological malignancy who are undergoing intensive chemotherapy need a central venous catheter (CVC)during their treatment. CVCs are locked with heparin when they are not used. The purpose of this study is to determine whether concentrated citrate locking, compared to heparin, reduces the incidence of central venous catheter-related thrombosis and infections in patients with hematological malignancies undergoing intensive chemotherapy.

This is a Phase 0/1 open-label, non-randomized, biomarker and pharmacodynamic study in patients with advanced B-cell lymphoid malignancies, including B-cell chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), acute lymphocytic leukemia (ALL), multiple myeloma (MM), Waldenström's macroglobulinemia (WM), mantle cell lymphoma, follicular lymphoma, or diffuse large B-cell lymphoma (DLBCL) who have failed at least one prior therapy and for whom no standard curative therapy exists. Patients with advanced stage disease are those whose disease is resistant or refractory to standard chemotherapy or biological therapies.

The primary objective of this study is to characterize the safety, tolerability, dose-limiting toxicities (DLTs), and maximum tolerated dose (MTD) of relatlimab administered alone or in combination with nivolumab to subjects with relapsed or refractory B-cell malignancies. Co-primary objective is to investigate the preliminary efficacy of relatlimab in combination with nivolumab in subjects with relapsed or refractory Hodgkin lymphoma (HL), and relapsed or refractory Diffused Large B Cell lymphoma (DLBCL)

While cord blood transplants have been performed safely in elderly patients, many still relapse. The investigators propose to intensify the preparative regimen for this patient group in an attempt to decrease relapses, and combine this with an ex vivo expanded Umbilical Cord Blood (UCB) unit.

This study is an open label, multicenter study with a dose escalation of Asparec® administered once every two to four weeks for two administrations. The primary objective of this study is to determine the Maximum Tolerated Dose following one single dose of Asparec when administered in a population of patients with relapsed or refractory hematological malignancies, as measured by Dose Limiting toxicities. There are secondary objectives which are to evaluate the safety of Asparec and to determine the PK profile as assessed by measurement of plasma L-asparaginase enzymatic activity following single and repeated doses of Asparec. Patients response rate will be evaluated and Anti-Asparec antibodies will be measured.

The purpose of this study is to assess transplant-related mortality (TRM) at one year after allogeneic hematopoietic stem cell transplantation (allo-HSCT) prepared by a "reduced toxicity myeloablative" conditioning regimen in young patients (children and adolescents) with hematologic malignancies.
