Filter by:Patients with bone marrow cancer are more susceptible to chest infections than healthy adults; marrow ablation treatment further compromises their immune status and increases the risk of fungal opportunistic infection, which is associated with a high fatality rate. Therefore, it is critical to achieve early and accurate diagnosis of fungal infection when these patients become febrile. At the Mount Sinai Hospital (MSH) and the University Health Network (UHN), the standard of care (SOC) to exclude a chest infection in immunocompromised (IC) patients is chest computed tomography (CT) using low dose CT (LDCTT).
Multi-site, non-randomized Phase I/II study involving children and adults.
This is a clinical study for adult patients who have recently been diagnosed with acute myeloid leukemia or AML. AML is a type of cancer. It is when bone marrow makes white blood cells that are not normal. These are called leukemia cells. Some patients with AML have a mutation, or change, in the FLT3 gene. This gene helps leukemia cells make a protein called FLT3. This protein causes the leukemia cells to grow faster. For patients with AML who cannot receive standard chemotherapy, azacitidine (also known as Vidaza®) is a current standard of care treatment option in the United States. This clinical study is testing an experimental medicine called ASP2215, also known as gilteritinib. Gilteritinib works by stopping the leukemia cells from making the FLT3 protein. This can help stop the leukemia cells from growing faster. This study will compare two different treatments. Patients are assigned to one of these two groups by chance: a medicine called azacitidine, also known as Vidaza®, or an experimental medicine gilteritinib in combination with azacitidine. There is a twice as much chance to receive both medicines combined than azacitidine alone. The clinical study may help show which treatment helps patients live longer.
The purpose of this phase I study is to investigate the combination of hypomethylating agents with experimental peptide vaccination against four selected tumor antigens, known to be upregulated in response to hypomethylating agents, in patients with high risk myelodysplastic syndrome and acute myeloid leukemia.
Allogeneic hematopoietic cell transplantation (allo-HCT) is a potentially curative therapy for patients with hematologic malignancies including acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), and acute lymphoblastic leukemia (ALL); however, human leukocyte antigen (HLA)-matched donor availability continues to be a major hurdle. Historically, HLA haploidentical donor hematopoietic cell transplantation (haplo-HCT) was associated with high incidences of graft rejection and excessive non-relapse mortality (NRM), but recent advances utilizing post-transplant cyclophosphamide (PT-Cy) have revolutionized haplo-HCT and the outcomes are now comparable to allo-HCT using more traditional HLA matched related and unrelated donors. However, graft-versus-host disease (GvHD) continues to be a problem and is associated with significant morbidity and mortality in allo-HCT patients including those who receive haplo-HCT on PT-Cy platform. The aim of this early phase study is to investigate the safety and overall efficacy of azacitidine in reducing the incidence and severity of GvHD when added to PT-Cy based haplo-HCT platform for patients with AML, ALL, or advanced MDS.
The purpose of this study is to evaluate the use of IRX5183 in 1) patients with relapsed and/or refractory AML and 2) patients with high-risk MDS or chronic myelomonocytic leukemia (CMML).
Aldehyde dehydrogenases (ALDHs) are cellular enzymes responsible for detoxifying aldehyde resulting from the metabolism of endogenous and exogenous xenobiotic cellular constituents. Although ALDHs are considered to play an important role in tumorigenesis, the role of ALDH activity in cancer stem cells, and more particularly that of the acute leukemia must be specified. Several studies have shown that ALDHs are potent apoptogenic compounds on normal or cancer cells. Therefore, the cells that were damaged and their increased ALDH activity does not die by apoptosis but become highly proliferating. This result is a plausible mechanism for the "evasion of apoptosis", a characteristic shared by many cancer cells. On this basis, it is proposed an innovative approach to cancer chemotherapy through inhibition of one of the protective mechanisms against apoptosis, ie the increase in ALDH activity than cancer cells put involved in overcoming the lethal effects of damaged roads. ALDHs of inhibitors they may have immediate application as anti -cancer in vivo? The limited experimental data obtained so far on human tumor xenografts in immunodeficient mice and the absence of data on the in vivo toxicology do not allow direct passage to clinical trials. Indeed, some members of the ALDH superfamily are expressed constitutively in some vital organs they protect against the deleterious effects of xenobiotics and adverse endogenous metabolites. Consequently, if ALDHs should be inhibited, of the collateral damages for the normal cells could occur. However, when normal cells have not undergone deleterious exposure, these harmful metabolites are not or in very small quantities, which do not require high levels of ALDH activity, and therefore without harm to the inhibition of cell of these enzymes. From a hematological point of view, it seems essential to test the therapeutic index of the inhibitor of ALDH DIMATE between normal hematopoietic cells and leukemic stem. Indeed, in the pathophysiology of acute leukemia, the leukemia stem cells are of major importance because they are much more resistant to chemotherapy than more differentiated cells and thus causing the high rate of relapse observed in acute leukemia despite the high rate of complete remission often obtained. In this study, it will be tested in vitro sensitivity of the cluster of differentiation 4 and cluster of differentiation 38 (CD4/CD38) highly purified of leukemic origin or normal to the DIMATE compound. The objective will be to analyze the effects of DIMATE on the parameters of the proliferation, the apoptose, the cytokinins of secretions and the changes transcriptomic in general, in order to better define the therapeutic index of this compound and to determine all the precursory hematopoietic normals and leukaemic cellular effects. The reversible cytostatic of DIMATE effect on normal cells but its irreversible apoptotic effect on cancer cells is an advantage to try to eliminate.
The study is in two parts: a dose escalation then a safety dose expansion. The purpose of the dose escalation part is to evaluate the safety and tolerability of ascending doses of UCART19 (dose-escalation part) given as a single infusion in patients with relapsed / refractory (R/R) B-cell acute lymphoblastic leukaemia (B-ALL), to determine the maximum tolerated dose (MTD), the recommended dose and the lymphodepletion regimen. The purpose of the safety dose expansion is to assess the safety and tolerability of the RD for UCART19.
This study aims at exploring the activity of a frontline approach based on dasatinib plus steroids administration as induction treatment, followed by the infusion of Blinatumomab, in adult Ph+ ALL.
Background: The Agricultural Health Study (AHS) studied farmers and their spouses in North Carolina and Iowa. It also included people who worked with pesticides in Iowa. They answered a questionnaire and gave data about their children born since 1975. Researchers want to link this data to public data like birth and death certificates. They want to study how early life exposures to farms are linked to cancer and other bad health outcomes. Objective: To study data to find links between early life farm exposure and negative health outcomes. Eligibility: There will be no human subjects. Design: Researchers will get public data in the two study states. This will come from things like: Birth certificates Driver s licenses Voter registration Death certificates Based on these plus the AHS data, they will create a study group. It will be called Early Life Exposure in Agriculture (ELEA). Researchers will link ELEA data to cancer data. This will identify prevalence of cancer. They will study parents answers on the AHS. The topics include farm practices and pesticide use. They will determine ELEA exposure to pesticides. Researchers will analyze the cancer and pesticide results and look for links.
