Filter by:The purpose of this study was to assess the efficacy and safety of individualized treatment of 6-mercaptopurine (6-MP) in Chinese children with acute lymphoblastic leukemia, and to investigate the dose-concentration-response (DER) relationship between thiopurine metabolites and adverse events. The individualized administration of 6-MP was established in Chinese children with acute lymphoblastic leukemia.
This was a multi-center Phase II study investigating the efficacy and safety of reinfusion of tisagenlecleucel in pediatric and young adult patients with acute lymphoblastic leukemia (ALL) who were treated with tisagenlecleucel and experience B cell recovery.
The purpose of this study is to find out whether a novel manualized intervention, called Emotion and Symptom-focused Engagement (EASE), that combines psychological support with symptom screening plus triggered referral to early palliative care for symptom control, reduces psychological distress and physical symptom burden in individuals newly diagnosed with acute leukemia. To do this, half of the participants in this study will receive the usual care offered to patients with acute leukemia and half of the participants will receive usual care plus the EASE intervention.
Relapsed acute lymphoblastic leukaemia (ALL) has a poorer outcome than newly diagnosed ALL patients with only about 40% overall survival after re-treatment. The study CCCG Relapsed ALL 2017 study will adopt the UK R3 study stratification and treatment backbone with two new agents added. There will be a 4-week induction, followed by two consolidation courses. High-risk patients will receive allogeneic stem cell transplant. While intermediate and standard risk groups will continue maintenance treatment for another 2 years or one year. New agents will be added aiming at improving survival outcome. 1. Study of adding anti-CD20 antibody (rituximab) with chemotherapy: CD20 is found to be expressed in 40-50% of B-lineage ALL, and rituximab has been studied in adult ALL with superior survival (75% vs 47%,). There is little experience of using rituximab in pediatric ALL thus a CCCG Relapsed ALL 2017 Study will perform the study assessing the remission rate and MRD response of CD20+ ALL treated with rituximab. Six doses of rituximab and will be monitored the week 5 MRD and relapse rate as study outcome. (This arm was terminated in October 2020 after interim analysis showing lack of efficacy) 2. Adding bortezomid during the induction: The very early or early bone marrow relapse has low remission rate. Previous case studies showed that Bortezomib, a proteasome inhibitor, may achieve remission in refractory ALL, 80% remission in B-ALL with combination of chemotherapy and bortezomib. Thus adding bortezomib, may improve the remission rate, thus bridging to allogeneic stem cell transplant. Adding bortezomib in the relapsed chemotherapy protocol may increase the toxicity and even treatment related mortality. In this protocol, we suggested to add during the induction therapy.
Natural killer (NK) cells exert antitumor effects via their cytotoxic and cytokine-secreting capacity without present of clinical symptoms. In recent years, with the continuous advancement of in vitro expansion methods, the application of good quality management technology, NK cells could be clinical grade expanded without the need for pre-purification, feeder-free, and serum-free culture. In this clinical trial the investigators want to demonstrate the safety and efficacy chemotherapy combined with donor-derived in vitro activated NK cells infusion for high risk AML patients.
This phase I trial studies the side effects of donor natural killer (NK) cell therapy in treating patients with acute myeloid leukemia that has come back (recurrent) or has not responded to treatment (refractory). Natural killer cells are a type of immune cell. Immunotherapy with genetically modified NK cells from donors may induce changes in the body's immune system and may interfere with the ability of cancer cells to grow and spread.
Patients eligible for this study have a type of blood cancer Acute Myeloid Leukemia (AML) which has come back or has not gone away after treatment. The body has different ways of fighting disease and infection, and this research study combines two different ways of fighting cancer with antibodies and T cells with the hope that they will work together. T cells (also called T lymphocytes) are special infection-fighting blood cells that can kill other cells including tumor cells. Antibodies are types of proteins that protect the body from bacterial and other infectious diseases. Both antibodies and T cells have been used to treat patients with cancers; they have shown promise, but have not been strong enough to cure most patients when used alone. T lymphocytes can kill tumor cells but there normally are not enough of them to kill all the tumor cells. Some researchers have taken T cells from a person's blood, grown more of them in the laboratory and then given them back to the person. The antibody used in this study targets CLL-1. This antibody sticks to AML cells because of a substance (protein) on the outside of these cells called CLL-1. For this study, the antibody to CLL-1 has been changed so that instead of floating free in the blood, it is now joined to the T cells. When T-cells contain an antibody that is joined to them, they are called chimeric antigen receptor T-cells or CAR-T cells. In the laboratory, the investigators have also found that T cells work better if proteins that stimulate T cells are also added, such as one called CD28. Adding the CD28 makes the cells grow better and last longer in the body, thus giving the cells a better chance of killing the leukemia or lymphoma cells. In this study we are going to attach the CLL-1 chimeric receptor that has CD28 added to it to the patient's T cells. We will then test how long the cells last. These CLL-1 chimeric antigen receptor T cells with CD28 are investigational products not approved by the Food and Drug Administration.
To evaluate safety, immunogenicity and anti-tumor responses of intradermally delivered SNS-301 in patients with ASPH+ high risk MDS and CMML.
Treatment options for older adults with Acute Myeloid Leukaemia (AML) and Myelodysplasia (MDS) are limited. Although stem cell transplantation remains one of the most effective treatments it is associated with severe side effects which have until recently prevented its use in older adults. In the last decade the use of reduced intensity transplants has allowed the extension of the potentially curative effect of transplantation to older patients in whom it was previously precluded. Although a major advance such transplants are associated with a high risk of disease relapse particularly in patients with high risk disease. This study will evaluate new transplant strategies with the aim of improving the outcome of patients with AML and high risk MDS after stem cell transplantation. Three approaches to improve transplant outcome will be studied: 1. Comparing the new pre-transplant consolidation therapy vyxeos with the standard consolidation therapy (Randomisation 1 is now closed to recruitment). 2. Comparing new conditioning therapies in patients under the age of 55 years 3. Comparing new conditioning therapies in patients aged 55 and over All patients will be followed up for a minimum of 2 years.
This phase II trial studies how well ABL001 works in treating patients with chronic myeloid leukemia who are on therapy with tyrosine kinase inhibitor. ABL001 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving ABL001 and tyrosine kinase inhibitor together may work better than tyrosine kinase inhibitor alone in treating patients with chronic myeloid leukemia.
