Active clinical trials for "Hematologic Neoplasms"

Patients with refractory hematologic malignancies including those who develop recurrent disease after allogeneic hematopoietic stem cell transplantation (HSCT) have a dismal prognosis. Historically, both regimen-related mortality and disease recurrence have been significant causes of treatment failure in this heavily pre-treated patient population. The investigators institution has utilized mismatched family member donors for these patients for several reasons: (1) Only 30% of patients have matched related donors available; (2) transplantation can be performed more rapidly since the time to unrelated donor trans-plantation averages 3 to 4 months; (3) the alloimmune reactivity of natural killer (NK) cells following haploidentical HSCT has been shown to reduce relapse rates in certain patient groups; and, (4) no other curative treatment options are available. In the present trial, the investigators propose a novel conditioning regimen using clofarabine in an effort to enhance cytotoxicity while simultaneously reducing regimen related toxicity. In this phase I trial, the goal is to determine the maximum tolerated dose (MTD) of clofarabine when used in combination with melphalan and thiotepa pre-transplant.

The purpose of this research study is to evaluate the effectiveness of transplantation of high doses of peripheral blood stem cells (stem cells are special cells found in the blood and bone marrow that produce new blood cells) after treatment with non-myeloablative chemotherapy (not toxic to the bone marrow). In addition, this study will assess the side effects of the transplant.

Patients who have cancer of the bone marrow (leukemia) or lymph gland (lymphomas) are being asked to take part in this study. This study uses a new chemotherapy regimen and matched volunteer stem cell transplant to treat patients with cancers of this kind.

This is a research study involving the treatment of leukemia or lymphoma (lymph gland cancer) in adults who have leukemia or lymphoma that is unlikely to be cured with regular anticancer drugs or radiation treatments.

This is a clinical research study designed to evaluate whether a conditioning regimen consisting of the combination of three drugs named melphalan, alemtuzumab and clofarabine supported by donor blood cells will result in rapid recovery and a high rate of long-lasting remissions in patients with leukemia, lymphoma and myeloma.

The purpose of this research study is to determine the safety and efficacy of a reduced intensity conditioning regimen during a double umbilical cord blood unit transplant with one of the cord blood units modulated with ProHema.

The investigators have previously shown that depletion of CD4+CD25+FoxP3+ regulatory T cells (Treg) enhances the alloreactivity of T lymphocytes, as attested by an accelerated GVHD after allogeneic hematopoietic stem cell transplantation (HSCT) in mice. The investigators thus propose a clinical trial to test whether Treg-depleted donor lymphocytes infusion (dDLI) could induce an improved graft-versus-tumor (GVT) effect in patients refractory to standard DLI (stdDLI) for treatment of relapse after HSCT.

This is a phase I study using Intensity Modulated Total Marrow Irradiation (IM-TMI) in addition to a chemotherapy regimen in preparation for an allogeneic stem cell transplant for advanced hematologic malignancies such as acute myeloid or lymphoblastic leukemia, high grade non Hodgkin's or Hodgkin's lymphoma, chronic myelogenous leukemia, and plasma cell leukemia. Because the subjects participating in this study have a disease that is severe and has a high risk of relapse even after transplant, the investigators propose to use a chemotherapy regimen (fludarabine/busulfan), the name for the combination of chemotherapy drugs that is given to patients prior to transplantation of the donor stem cells, along with intensity modulated radiation (IM-TMI) to the bone marrow. Total body irradiation (TBI) in conjunction with chemotherapy is a standard of care as a pre-conditioning regimen prior to bone marrow transplant (BMT) in patients with hematologic malignancies. However, TBI can cause severe side effects due to irradiation of organs such as the lenses of the eye, whole brain, lungs, liver, kidneys, heart, small bowel and oral cavity. IM-TMI allows for the delivery of adequate doses of radiation to the bone marrow while sparing other organs and therefore limiting radiation side effects. The irradiation, along with receiving the chemotherapy drugs will suppress the subject's immune system and kill off tumor cells, but will also intensify the effect of the conditioning regimen thus allowing the bone marrow transplantation to have a greater chance of being successful. No investigational drugs are used in this study. The investigational part of this study is the use of intensity modulated total marrow irradiation instead of conventional radiation. IMTMI can deliver 99% of the prescribed treatment to the targeted bones and reduce the doses of radiation to surrounding organs, as received in conventional TBI, by 29% to 65%.

This study evaluated safety, tolerability, pharmacokinetics and preliminary anti-leukemic or anti-tumor activity of LBH589B in adult patients with advanced hematological malignancies

This is an open-label, multicenter, phase 1 study of MLN8237 in participants with advanced hematological malignancies for whom there are limited standard treatment options.
