Filter by:This study is a dose escalation, and cohort expansion study in subjects with advanced cancer for which no standard therapy exists. Subjects must have received prior treatment for cancer that has not worked, or has stopped working.
This study is a means of providing transplantation to those patients who would be a stem cell transplant candidate who do not have an appropriate donor. The use of CD34 selected haploidentical donor with an umbilical cord unit may help provide earlier engraftment without the need for long term immunosuppression. This study tests a new method of bone marrow transplantation called combined haploidentical-cord blood transplantation. In this procedure, some of the blood forming cells (the stem cells) from a partially human leukocyte antigen (HLA) matched (haploidentical) related donor are collected from the blood, as well as cells from an umbilical cord are transplanted into the patient (the recipient) after administration of a "conditioning regimen". A conditioning regimen consists of chemotherapy and sometimes radiation to the entire body (total body irradiation, or TBI), which is meant to destroy the cancer cells and suppress the recipient's immune system to allow the transplanted cells to take (grow).
The present project aims at evaluating the capacity of MSC to improve one-year overall survival of patients transplanted with HLA-mismatched PBSC from related or unrelated donors after non-myeloablative conditioning. Co-infusion of MSC has been shown to facilitate engraftment of hematopoietic stem cell (HSC) in an immunodeficient mouse model. In addition, it has been shown that infusion of third party MSC in HSC transplantation could be successfully used as treatment for grade II-IV steroid-refractory acute graft versus host disease. One hundred and twenty patients with HLA-mismatched donors will be included over 6 years at multiple centers across Belgium through the transplant committee of the Belgian Hematological Society. The conditioning regimen will consist of fludarabine and 2 Gy TBI, followed by the infusion of donor HSC. Patients will be randomized 1/1 in double-blind fashion to receive or not MSC (1.5-.3.0 x106/kg) from third-party (either haploidentical family members or unrelated volunteer) donors on day 0. Postgrafting immunosuppression will combine tacrolimus and MMF. Except for the collection, expansion and infusion of MSC, the clinical management of the patient will not differ from that of routine NM-HCT.
The purpose of this research study is to see if the investigational drug EL625, when combined with traditional chemotherapy (rituximab, fludarabine, and cyclophosphamide), is effective in Persistent Chronic Lymphocytic Leukemia (CLL) and Small Lymphocytic Lymphoma (SLL)
The purpose of this study is to determine whether the addition of parathyroid hormone after a sequential cord blood transplant will improve engraftment, which is the ability of the transplanted stem cells to grow and to successfully begin producing new blood cells.
The purpose of this study is to determine how well subjects respond to treatment with Rituximab plus Beta-Glucan.
The purpose of this study is to develop a standard of care treatment using allogeneic stem cells for patients with cancers of the blood. The protocol was revised to reflect that this study is considered "treatment guidelines", rather than a research study.
The purpose of this study is to test the hypothesis that a pre-infusion preparative regimen of cyclophosphamide and fludarabine will improve the effectiveness of DLI in patients with blood cancers.
This pilot study will assess the safety and efficacy of Pivanex alone in patients with chronic lymphocytic leukemia (CLL) who have relapsed or refractory disease after previous chemotherapy treatment. Pivanex is an investigational agent.
The purpose of this study is to determine if the drug motexafin gadolinium will be an effective treatment for patients who have chronic lymphocytic leukemia (CLL) that has come back after treatment or that has stopped responding to treatment.
