Filter by:This phase II trial studies how well donor umbilical cord blood transplant with ex-vivo expanded cord blood progenitor cells (dilanubicel) works in treating patients with blood cancer. Before the transplant, patients will receive chemotherapy (fludarabine, cyclophosphamide and in some cases thiotepa) and radiation therapy. Giving chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. It may also stop the patient's immune system from rejecting the donor's stem 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. The donated stem cells may also replace the patient's immune cells and help destroy any remaining cancer cells.
Patients with low-risk MDS verifying the eligibility criteria may be included in the study.
This phase II trial studies the side effects and how well azacitidine and enasidenib work in treating patients with IDH2-mutant myelodysplastic syndrome. Azacitidine and enasidenib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
The purpose of this study is to evaluate of the clinical efficacy and safety of DLAAG protocol in the treatment of acute myeloid leukemia (AML) and myelodysplastic syndrome with blast excess
The main purpose of this study is to verify the safety and potential effectiveness of CART cells combined with peptide specific dendritic cell in relapsed/refractory leukemia.
Database of Institut Paoli-Calmettes patients diagnosed with Myelodysplastic Syndromes
The investigators focused on patients with refractory acute leukemia or MDS and designed a phase 1 trial of escalated cladribine doses in the Cla-Flu-Bu RTC regimen using PK-guided myeloablative busulfan doses. This scheme allows combining different optimization of RTC experienced over years (Flu-Bu RTC, PK-guided myeloablative busulfan doses, a second purine analog cladribine) to approach a specific platform to treat refractory diseases.
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.
Background: Severe aplastic anemia (SAA) and myelodysplastic syndrome (MDS) are bone marrow diseases. People with these diseases usually need a bone marrow transplant. Researchers are testing ways to make stem cell transplant safer and more effective. Objective: To test if treating people with SAA or MDS with a co-infusion of blood stem cells from a family member and cord blood stem cells from an unrelated donor is safe and effective. Eligibility: Recipients ages 4-60 with SAA or MDS Donors ages 4-75 Design: Recipients will be screened with: - Blood, lung, and heart tests - Bone marrow biopsy - CT scan Recipients will have an IV line placed into a vein in the neck. Starting 11 days before the transplant they will have several chemotherapy infusions and 1 30-minute radiation dose. Recipients will get the donor cells through the IV line. They will stay in the hospital 3-4 weeks. After discharge, they will have visits: - First 3-4 months: 1-2 times weekly - Then every 6 months for 5 years<TAB> Donors will be screened with: - Physical exam - Medical history - Blood tests Donors veins will be checked for suitability for stem cell collection. They may need an IV line to be placed in a thigh vein. Donors will get filgrastim injections daily for 5-7 days. On the last day, they will have apheresis: Blood drawn from one arm or leg runs through a machine and into the other arm or leg. This may be repeated 2 days or 2-4 weeks later.
