This is an open-label, randomized, multicenter, phase III study Patients with baseline Hb comprised between 9 and 10.5g/dl will be randomized to receive EPO Alfa 60000 UI/week for at least 12 weeks: - Either at diagnosis Or - at the Hb threshold chosen for RBC transfusions (must be < 9g/dl)
Myelodysplastic syndromes (MDS) are the most frequent myeloid neoplasms in Western Countries.They mainly affect patients aged 65 years or older. This is a very heterogenous group of diseases, which prognosis is evaluated with International Prognosis Scoring System. High risk MDS present with high frequency of transformation into acute myeloid leukemia. Treatment of high risk MDS often is based on hypomethylating agents, such as 5'-azacytidine (Azacytidine), with a complete response in approximativel 20% of cases.. This treatment is based on 4-week cycles, with daily injection during the first week and rest during the 3 next weeks of the cycle. Azacytidine efficacy is commonly evaluated with clinical and biological parameters determined by the International Working Group 2006. These parameters are usually evaluated after at least 6 cycles of treatments. There is a response with Azacytidine treatment in 60% of cases, including 40% of partial responses and 20% of complete responses. In 40% of patients, there is no response, which means that the disases is stable or in progression under therapy. In this regard, early evaluation of treatment response is an issue. We want to improve our knowledge about early response criteria in Azacytidine-treated high-risk MDS, focusing on SMD with excess blasts, which represent 30 to 40% of total MDS. Then, the investigator team want to compare DNA methylation profile at diagnosis and after 3 cycles of Azacytidine treatment. Main objective : Identify DNA methylation profiles related to response to Azacytidine therapy, after only 3 cycles of treatment, in high risk MDS with excess blasts. Secondary objective : Identify at diagnosis DNA methylation profiles that are predicitive of response to Azacytidin, in high risk MDS with excess blasts.
This is a multi-center Phase I/II clinical trial of GTB-3550 (CD16/IL-15/CD33) tri-specific killer cell engager (TriKE®) for the treatment of CD33-expressing high risk myelodysplastic syndromes, refractory/relapsed acute myeloid leukemia or advanced systemic mastocytosis. The hypothesis is that GTB-3550 TriKE® will induce natural killer cell function by targeting malignant cells as well as CD33+ myeloid derived suppressor cells (MDSC) which contribute to tumor induced immunosuppression. Because CD16 is the most potent activating receptor on natural killer (NK) cells, this single agent may induce a targeted anti-CD33+ tumor response.
This phase Ib/II trial studies the best dose and side effects of venetoclax and how well it works when given with combination chemotherapy in treating patients with newly diagnosed acute myeloid leukemia or acute myeloid leukemia that has come back or does not respond to treatment. Venetoclax may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as fludarabine, cytarabine, filgrastim and idarubicin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving venetoclax together with combination chemotherapy may work better in treating patients with acute myeloid leukemia.
A significant number of patients with hematologic malignancies need a hematopoietic stem cell transplant (HSCT) to be cured. Only about 50% of these patients have a fully matched donor, the remaining patients will require an HSCT from a mismatched related or unrelated donor. Almost 60% of these mismatched donor HSCTs will result in graft-versus-host disease (GvHD), which can cause significant morbidity and increased non-relapse mortality. GvHD is caused by the donor effector T cells present in the HSC graft that recognize and react against the mismatched patient's tissues. Researchers and physicians at Lucile Packard Children's Hospital, Stanford are working to prevent GvHD after HSCT with a new clinical trial. The objective of this clinical program is to develop a cell therapy to prevent GvHD and induce graft tolerance in patients receiving mismatched unmanipulated donor HSCT. The cell therapy consists of a cell preparation from the same donor of the HSCT (T-allo10) containing T regulatory type 1 (Tr1) cells able to suppress allogenic (host-specific) responses, thus decreasing the incidence of GvHD. This is the first trial of its kind in pediatric patients and is only available at Lucile Packard Children's Hospital, Stanford. The purpose of this phase 1 study is to determine the safety and tolerability of a cell therapy, T-allo10, to prevent GvHD in patients receiving mismatched related or mismatched unrelated unmanipulated donor HSCT for hematologic malignancies.
This pilot clinical trial compares the safety of two different platelet transfusion "thresholds" among patients with blood cancer or treatment-induced thrombocytopenia whose condition requires anticoagulant medication (blood thinners) for blood clots. Giving relatively fewer platelet transfusions may reduce the side effects of frequent platelet transfusions without leading to undue bleeding.
This phase Ib/2 trial studies how well chemotherapy, total body irradiation, and post-transplant cyclophosphamide work in reducing rates of graft versus host disease in patients with hematologic malignancies undergoing a donor stem cell transplant. Drugs used in the chemotherapy, such as fludarabine phosphate and melphalan hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy and total-body irradiation before a donor stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When the healthy stem cells from a donor are infused into the patient, they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft versus host disease). Giving cyclophosphamide after the transplant may stop this from happening.
This is a phase 1 study of investigational drug CFI-400945 in patients with relapsed or refractory acute myeloid leukemia or myelodysplastic syndrome. The purpose of this phase 1 study is to see how safe and tolerable the study drug is and to determine the best dose (maximum tolerated dose or recommended phase 2 dose) that can be given in this patient population.
The purposes of the study is to determine the safety and efficacy of human umbilical cord mesenchymal stem cells (hUC-MSC) in treating Myelodysplastic Syndrome patients.
