Filter by:This is a randomized trial for patients undergoing hematopoietic progenitor cell transplantation (HPCT) from an unrelated donor. Approximately 50% of the patients enrolled will receive Thymoglobulin® as part of the preparative regimen prior to HPCT. The other 50% of the patients enrolled will receive a standard preparative regimen. Thymoglobulin is known to suppress the types of cells that can cause a transplant complication known as "chronic graft versus host disease (cGVHD)". The goal of this trial is to find out if adding Thymoglobulin to the preparative regimen will result in a decrease in cGVHD.
If transplantation using mismatched unrelated donors or non-first-degree relatives could be performed with an acceptable toxicity profile, an important unmet need would be served. Towards this goal, the current study extends our platform of nonmyeloablative, partially HLA-mismatched bone marrow transplant (BMT) and Peripheral Blood Stem Cell Transplant (PBSCT) to the use of such donors, investigating up to several postgrafting immunosuppression regimens that incorporate high-dose Cy. Of central interest is the incorporation of sirolimus into this postgrafting immunosuppression regimen. The primary goal for phase 1 is to identify a transplant regimen associated with acceptable rates of severe acute GVHD and NRM by Day 100 and for phase 2 estimate the 6-month probability of survival without having had acute grade III- IV GVHD or graft failure.
The purpose of this study is to evaluate the safety, determine the maximum tolerated dose (MTD) and schedule of IPI-493 in patients with hematologic malignancies.
The purpose of the Phase IIA study are to: 1. define the safety profile 2. evaluate the efficacy of a sequential infusion of unmanipulated Donor Lymphocyte Infusions (DLI) and Cytokine Induced Killer (CIK) cells for the treatment of molecular, cytogenetic or hematologic relapse after hematopoietic stem cell transplantation and The progression free survival and the overall survival after the sequential infusion of Donor Lymphocyte Infusions (DLI) and Cytokine Induced Killer(CIK) cells.
To exploit the curative potential of allografting, the ultimate clinical goal is to separate GVL from GVHD. In murine preclinical models, recipients of allogeneic hematopoietic cell transplants after a preparative regimen of total lymphoid irradiation (TLI) and antithymocyte globulin (ATG) did not develop GVHD. The murine TLI/ATG study was turned into a clinical phase I protocol for patients with hematological malignancies, and a reduction of acute GVHD to < 3% was observed (Lowsky R et al, N Engl J Med). This suggests that specific immune mechanisms control GVHD and preserve GVL. The study will include patients with lympho and myeloproliferative diseases. The conditioning regimen will consist of TLI [ten 80 cGy fractions on day -11 through day -7 and on day -4 through day -1; the radiation field (four fields-two anterior and two posterior) involves all major lymphoid organs including the thymus, spleen and lymph nodes] and ATG (five i.v. doses at 1.5 mg/kg/day from day -11 through day -7). G-CSF mobilised hematopoietic cells, collected on days -1 and 0, from HLA-identical siblings or unrelated donors will be infused on day 0. Post-transplant immunosuppression will consist of oral cyclosporine (at 6.25 mg/kg/d) from day -3 and micophenolate mophetile (at 15 mg/Kg bid) from day +1. The clinical primary objective is to reduce the incidence of GVHD to < 5%, with better survival and quality of life.
Study objectives To evaluate the safety of the echinocandin anidulafungin for prophylaxis or treatment of invasive fungal infections (IFI) in hematologic patients. Study design, Study conduct period Prospective, open label, phase II, one arm, single centre study October 2009 - September 2010 Study population Twenty adult patients (≥ 18 years) with a hematologic disorder and an indication for antifungal prophylaxis or therapy, but a relative contraindication for azoles or polyenes due to hepatic and renal dysfunction respectively Methods and Main Out-come Variables Main Outcome Parameter Safety: Adverse events and changes of important laboratory parameters with clinical impact will be reported. Secondary Outcome Parameter Efficacy: In therapeutically use the outcome will be categorized into success or failure. For patients receiving anidulafungin as prophylaxis the number and rate of breakthrough infections will be documented. Risk assessment Treatment related adverse effects as reported in the approved physician prescribing information (usually mild and with an incidence of < 5%). Treatment failure due to resistant pathogens. Expected benefit from this study IFI is a major cause of death among hematological patients, especially those undergoing high dose chemotherapy. It is conceivable that anidulafungin is a new treatment option for patients in whom azoles or polyenes are relatively contraindicated.
The goal of this clinical research study is to learn about the safety of giving a stem cell transplant from a tissue-mismatched donor, followed by cyclophosphamide, to patients with certain types of blood disorders or blood cancers. Melphalan, thiotepa, and fludarabine will also be given before the transplant. Researchers will study the health status of these patients at 3 months after the transplant.
The purpose of this study is to determine the maximum tolerated dose and evaluate the safety of the administration of donor lymphocytes depleted of alloreactive T-cells following a stem cell transplant from a related, haploidentical donor, in patients with severe hematologic malignancies.
This study examines the effect of a small molecule inhibitor to the Sonic Hedgehog pathway on select hematologic malignancies.
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.
