Active clinical trials for "Hematologic Neoplasms"

The purpose of this study is compare the efficacy of haplo-cord transplant (investigational arm) with that of a more commonly used procedure in which only the cells contained in one or two umbilical cords are infused (standard arm). We hypothesize that reduced intensity conditioning and haplo-cord transplant results in fast engraftment of neutrophils and platelets, low incidences of acute and chronic graft versus host disease, low frequency of delayed opportunistic infections, reduced transfusion requirements, shortened length of hospital stay and promising long term outcomes. We also hypothesize that umbilical cord blood selection can prioritize matching and better matched donors can be identified rapidly for most subjects.

Allogeneic stem cell transplantation is a potentially curative treatment for patients with many hematologic malignancies (e.g. leukemia, lymphoma, and myeloma with high risk of relapse). This process requires a suitable donor. The best case scenario involves an Human Leukocyte Antigen (HLA) matched sibling donor. However, this type of donor is not always available. Donor registries can provide another source for matched unrelated donors, but this may take valuable time delaying treatment for the transplant recipient. Donor availability remains a significant barrier to the use of allogeneic (from a donor) stem cell transplant. This issue disproportionately affects patients of minority backgrounds. Novel strategies to improve outcomes using alternative donors are desperately needed. Haploidentical transplants are an alternative which provides a readily available donor in the form of a partially HLA matched family member. This provides for more potential donors and the donors can be selected based on other factors that can play a role in transplant success (e.g. age, gender, KIR alloreactivity). Recent advances in transplant techniques have greatly improved success rates with haploidentical transplants although disease relapse has remained as issue. This trial aims to provide an alternative transplant option for patients with hematologic malignancies who require bone marrow transplantation but lack an HLA identical donor. The investigational component of this study is the combination of the Fludarabine/ Busulfan/ Total Body Irradiation conditioning regimen and the HLA Haploidentical Transplant with post-transplant Cyclophosphamide.

The purpose of this study is to determine the safety, maximum tolerated dose and pharmacokinetics of IPI-145 in patients with advanced hematologic malignancies.

This phase I trial studies the side effects and best dose of donor cord blood T-cells after stem cell transplant in treating patients with relapsed hematological malignancies. After umbilical cord blood transplant, stem cells are collected from the donor's cord blood and stored. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by treatment. Removing the T cells and treating them in the laboratory before infusing them in the patient may also help boost the patient's immune system.

Open label, dose finding trial to assess the efficacy of Treg/Tcon addback to partially matched related donor stem cells. The maximum tolerated dose will be established using 3 subjects per dose level, with an expansion cohort at the maximum tolerated dose.

The purpose of this signal seeking study is to determine whether treatment with LGX818 demonstrates sufficient efficacy in select pathway-activated solid tumors and/or hematologic malignancies to warrant further study

Background: Allogeneic hematopoietic stem cell transplantation (allotransplant) has been used to treat many kinds of cancer that develop in cells from the blood or immune system. After allotransplant, donor cells take over production of the recipient s blood and immune cells, and donor immune cells can directly attack and control tumor. However, for cancers that do not respond to allotransplant, there are no proven cures. A single treatment with radiation can improve the potency of immune-cell therapies. This is probably because the tumor tissue is damaged in a way that new tumor proteins are exposed, attracting immune cells to the tumor. By giving only a single dose of radiation, the immune cells that are attracted to the tumor are allowed to survive and function in their usual way, traveling throughout the body and educating other immune cells to recognize tumor, and to activate and expand in order to kill the tumor cells. Some research has shown that radiation may have a widespread effect on stimulating the immune system, educating immune cells to recognize and control tumors that have not been radiated. Objectives: - To determine whether a single treatment of radiation will help donor immune cells control cancer after allotransplant without causing excessive side effects. Eligibility: Recipients: Individuals 18 years of age and older who have blood cancers that have not responded to allotransplant. Donors: Healthy individuals 18 years of age and older who were previous allotransplant donors for one of the study recipients. Design: Donors will provide additional blood immune cells, called lymphocytes, through apheresis. Apheresis involves drawing blood, separating out the lymphocytes, and returning the rest of the blood to the donor. Recipients will receive a single dose of radiation to the greatest amount of tumor that can be irradiated safely. Researchers will intentionally leave some tumor that will not be radiated in order to evaluate whether there is a widespread response to the treatment. There are two treatment arms on the study. Arm 1: Study participants who have donor lymphocytes available and who have not had major complications from the allotransplant will be given a dose of donor cells after they receive radiation, to provide an additional boost to the donor immune response. Arm 2: Study participants who cannot receive donor lymphocytes because their donor is not available, they received an allotransplant from a partially matched relative, or they have had significant complications from the allotransplant - will receive radiation without additional donor lymphocytes. All recipients will be followed closely for side effects and for tumor response to radiation with or without donor lymphocytes. Additional tests will be performed, including tumor biopsies, bone marrow samples, and blood draws, in order to study the immune effects of radiation and donor lymphocytes. A separate, control group of allotransplant recipients will not receive radiation. This group will include participants whose transplant doctors plan to use donor lymphocyte therapy alone to control cancer progression. This group will donate blood immune cells through blood draws and apheresis. These cells will be examined to study the immune effects of receiving donor lymphocytes without radiation.

The purpose of this study is to determine the maximum tolerated dose (MTD), activity, and safety of oprozomib in patients with hematologic malignancies.

This is an open-label, multi-center, dose-escalation trial of pimasertib (MSC1936369B) in blood and bone marrow cancers. The trial will be conducted in two parts: Part 1 (safety run-in period): Will determine the maximum tolerated dose (MTD) of the study drug in subjects with advanced hematological malignancies. Part 2: Will assess the anti-leukemic activity of the study drug in older subjects with newly diagnosed poor prognosis acute myeloid leukemia (AML) who are not candidates for intensive chemotherapy.

This is an open-label, single arm phase 1 study to evaluate the dose-limiting toxicity, maximum tolerated dose, and recommended phase II dose of Clioquinol in patients with relapsed or refractory hematologic malignancies. The study will also characterize Cliquinol's safety, tolerability and pharmacodynamic effect.
