Filter by:The purpose of this Phase I, multicenter study is to evaluate the safety, pharmacokinetics, pharmacodynamics and clinical activity of AG-120 in advanced hematologic malignancies that harbor an IDH1 mutation. The first portion of the study is a dose escalation phase where cohorts of patients will receive ascending oral doses of AG-120 to determine maximum tolerated dose (MTD) and/or the recommended Phase II dose. The second portion of the study is a dose expansion phase where four cohorts of patients will receive AG-120 to further evaluate the safety, tolerability, and clinical activity of the recommended Phase II dose. Additionally, the study includes a substudy evaluating the safety and tolerability, clinical activity, pharmacokinetics, and pharmacodynamics of AG-120 in subjects with relapsed or refractory myelodysplastic syndrome with an IDH1 mutation. Anticipated time on study treatment is until disease progression or unacceptable toxicity occurs.
The NK cells participate in the innate immunity against infectious agents or transformed cells that are recognized as "no self" by the absent, weak or abnormal expression of human leukocyte antigen (HLA) class I molecules. According to the "missing self hypothesis", a negative signal is delivered to NK cells when their inhibitory receptors are engaged by the specific HLA class I molecules. NK activation requires a positive signal delivered by the engagement of activating receptors, more particularly of the "Natural cytotoxicity receptors" or NCRs who are directly involved in the natural cytotoxicity of Natural Killer. The activating receptors include NKp46, NKp44 and NKp30, also called NCR 1, 2 and 3 respectively. NKp46 and NKp30 are constitutively expressed on the surface of the NK, the expression of NKp44 is observed only after activation of cells NK. NK cells from most (80%) healthy donors express a high quantity of NCR on their surface, corresponding to the NCRbright phenotype while only 20 % present the NCRdull phenotype. In sharp contrast, most patients (80%) having leukaemia have the NCRdull while only 20 % patients have the NCRbright phenotype. The culture of NK from healthy donors ( NCRbright) with leukaemic cells result in decreased expression of the NKp30 while there is no difference on expression if these same NK are cultivated with cells from healthy donors. Moreover, study of AML patients showed that the NCRdull phenotype was acquired during leukemia development because it was observed its complete (for NKp46) or partial (for NKp30) reversibility in patients achieving complete remission (CR). Reversibility of the NCRdull phenotype after CR suggested that leukemia cells might be involved in NCR down-regulation. In line with these observations, we aim to study the mechanism of NCR down-regulation by cultivating NK NCRbright from healthy donors with leukaemic cells or healthy haematopoietic cells, in order to observe the appearance of the NCRdull phenotype and verify by qPCR if this down-regulation is transcriptionnal. If this hypothesis is be verified, we will study the regulation of NCR by focusing on the implication of genes NCR transcription factors via bio-informatic analysis of putative transcription factors fixation sequences in the promoters of these genes, followed by the verification of the capacity of identified sequences to bind transcription factors. Ultimately, we will verify the real implications of these transcription factors by studying the effect of their silencing by RNA interference experiments.
This research study is a Pilot study (a small preliminary study to assess the feasibility of a larger, more in depth study involving a new test or procedure) and is being done to evaluate the feasibility and accuracy of PET/MRI in the evaluation of cancer. PET/MRI is a FDA approved technology that is currently being studied to assess its accuracy and utility in the diagnosis and management of a variety of diseases and patient populations. The focus of this particular study will be to compare the performance of PET/MRI in its ability to detect and characterize cancerous tumors using positron emission topography and computed tomography (PET/CT) as a reference standard.
The purpose of this study is to determine whether certain genes in cancer may be abnormal. When a gene is abnormal this is called a mutation. Most mutations in cancer cells are not inherited (passed down from parents) but happen after birth in the cancer itself. Most cancers have many mutations. Some of these mutations are important for the cancer cells to survive while others are not. The goal of this study is test cancer for certain mutations using leftover tumor tissue from a previous surgery or biopsy. Participants will also be asked to provide a tube of blood cheek (also known as a buccal) swab, or a saliva sample that contains normal genes for comparison. The purpose of Part B of this study is to: Understand how genetic changes in tumor effect the chance of responding to experimental cancer treatment. Understand how the genes in the tumor change overtime in response to targeted cancer treatment.
Allogeneic haematopoietic stem cell transplantation (HSCT) is a potentially curative therapy for patients with both haematological and some non-haematological disorders. However, one of the major limiting factors for transplantation is the inability to identify a suitable HLA-matched donor. Development of an cost-effective and clinically efficacious alternative to HLA-identical sibling or unrelated donor transplantation would significantly expand the availability of allogeneic HSCT to patients in Singapore. Preliminary results indicate that the use of high dose post-transplant cyclophosphamide (Cy) for graft versus host disease (GVHD) prophylaxis in haplo-identical allogeneic HSCT is associated a low incidence of GVHD and low treatment related toxicity. We propose a phase II clinical trial to assess the efficacy of a haplo-identical allogeneic transplantation protocol using high dose post-transplant Cy for the treatment of patients with haematological disorders. A non-myeloablative protocol (Fludarabine-low dose cyclophosphamide-TBI) will be used for patients with bone marrow failure syndromes and indolent lymphoid disease. In view of the higher relapse risk of patients with myeloid malignancies, these patients will be treated with a reduced intensity conditioning regimen (Fludarabine-Busulphan). The primary end-point of the study will be overall survival at one year. Economic cost of the haplo-identical transplantation, as well as treatment timelines will be recorded and compared will other forms of unrelated donor allogeneic transplantation (umbilical cord blood transplantation and unrelated HLA-matched adult donor). Immunological reconstitution of patients following haplo-transplantation will be analysed and data will be utilized to guide future immunotherapy strategies post-transplantation. One year survival after non-myeloablative haploidentical stem cell transplantation is not inferior to that observed after non-myeloablative volunteer unrelated donor or unrelated cord blood haematopoietic stem cell transplantation.
Cord blood (CB) from an unrelated donor is increasingly used an alternative source of hematopoietic stem cells for adults with hematologic malignancies who lack an HLA-matched donor. However, the utilization of single-unit CB for transplantation of adult patients has been impeded by the low number of nucleated cells available from individual CB units. Direct intrabone CB injection (IBCBi) has been recently investigated as a solution to cell dose problem in adults, with the aims of minimizing non-specific loss of progenitors. We set up a phase I-II study to assess the safety and efficacy of CB transplantation by IBCBi in adult patients with advanced or high-risk hematological malignancies
Background: - Cord blood transplants can treat cancers and other diseases in children and adults. The U.S. Food and Drug Administration (FDA) requires cord blood to be collected and stored under certain safety standards. However, most available cord blood units were collected before the FDA set these standards. These units may not meet FDA standards, but they do meet similar standards set and followed by the National Marrow Donor Program (NMDP). Cord blood units that do not meet the new FDA standards may be used for transplants only as part of a research study. Doctors want to allow people who need transplants to receive cord blood that meets NMDP standards but may not meet FDA standards. Objectives: - To allow selected cord blood units that do not meet current FDA standards to be used for transplant. Eligibility: - Individuals who need cord blood units for transplant, and who best match cord blood units that are not FDA-licensed. Design: - Participants will provide consent to receive cord blood that meets NMDP standards but may not meet FDA standards. - Participants will remain on the study for observation for up to 1 year after transplant, or until they withdraw from the study for personal or medical reasons....
The aim of this study : 1. Through the study of genes of protein, transporter, translator and epigenome investigating the effect of anti-cancer treatment or the key factor of the MDR (Multidrug resistance) on the blood cancer patients who are under the anti-cancer sork treatment 2. Giving a service of anticancer medicine therapeutic drug monitoring (TDM) and genotyping
For the next 5-10 years or possibly longer, a high proportion of the Cord Blood Banks (CBB) inventory worldwide will be composed of unlicensed umbilical cord blood (UCB) units. While Food and Drug Administration (FDA)-licensed units will be prioritized, it will always be possible that an unlicensed unit will have known attributes, making it a better source of cells for the given indication. Because of the wide variety of current and potential indications as a source of cells for hematopoietic reconstitution or other form of cellular therapy, it is critical that the investigators have access to unlicensed UCB units.
The purpose of this study is to determine if engraftment can be achieved safely in patients with high-risk hematologic malignancies who undergo non-myeloablative transplant with peripheral stem cells from Human Leukocyte Antigen (HLA) haploidentical donors with pre and post-transplant cyclophosphamide as immunosuppression.
