Filter by:This is a single arm, open-label, multi-center, phase III B study to determine the safety and efficacy of CTL019 in pediatric/young adult patients with r/r B-cell Acute Lymphoblastic Leukemia (ALL).
Metformin's Antitumor activity were identified from differens diabetic patients trials, mainly associated to its mechanism of action and protein - kinase AMPK (AMP-activated protein kinase) activation. According to Cancer and Diabetes International Consensus from 2012, diabetes increases the risk for developping cancer and metformin has an protector effect against cancer cells and has an impact on overall survival. Chemotherapy drug resistance induces treatment fail in oncology. Metformin increases AMPK levels, blocks PI3K (phosphatidylinositol 3- kinase)/ AKT /mTOR(mammailian Target of Rapamycin) pathway but few evidence associated with drug resistance gene expression. This is an, experimental one-center study that pretends to stablish the effect of adding metformin 850 mg PO three times a day over the multi-drug resistance gene expression (ABCB1) in de novo Acute Lymphoblastic Leukemia in one 7-days cycle with prednisone as pre-treatment- and on the induction remission treatment.
This phase II trial studies how well an umbilical cord blood transplant with added sugar works with chemotherapy and radiation therapy in treating patients with leukemia or lymphoma. 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. 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 umbilical cord blood cells will be grown ("expanded") on a special layer of cells collected from the bone marrow of healthy volunteers in a laboratory. A type of sugar will also be added to the cells in the laboratory that may help the transplant to "take" faster.
This phase II trial studies how well etoposide, prednisone, vincristine sulfate, cyclophosphamide, and doxorubicin (DA-EPOCH) works in treating patients with acute lymphoblastic leukemia or lymphoblastic lymphoma. Drugs used in chemotherapy, such as etoposide, prednisone, vincristine sulfate, cyclophosphamide, and doxorubicin, 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.
- Exercise programs in children and teenagers with Acute Lymphoblastic Leukemia (ALL) strengthens their physical fitness. - Exercising improves muscular and functional mobility fitness after finalizing chemotherapy in children and teenagers diagnosed with ALL. - Assess cardiological changes
This pilot phase I trial studies the side effects of engineered donor stem cell transplant in treating patients with hematologic malignancies. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft-versus-host disease). Using T cells specially selected from donor blood in the laboratory for transplant may stop this from happening.
Acute Lymphoblastic Leukaemia (ALL) is the most frequent cancer in children. The survival rate has improved significantly during the last decades, but the treatment still fails to cure 15 % of the patients. Within the Nordic/Baltic countries, children are treated according to the same protocol, i.e. NOPHO ALL-2008 protocol. Children and adolescents with Lymphoblastic Non-Hodgkin's Lymphoma (LBL) are treated in accordance with the EURO-LB 02 protocol, whereas adults with Lymphoblastic Non-Hodgkin's Lymphoma in Denmark are commonly treated in accordance with the NOPHO ALL-2008 protocol. The longest treatment phase in both protocols is maintenance therapy, which is composed of 6-Mercaptopurine (6MP) and Methotrexate (MTX). The cytotoxic property of 6MP relies upon conversion of 6MP into thioguanine nucleotides (TGN), which can be incorporated into DNA instead of guanine or adenine. This incorporation can cause nucleotide mismatching and cause cell death second to repetitive activation of the mismatch repair system. At Rigshospitalet investigators have developed pharmacological methods able to measure the incorporation of TGN into DNA (DNA-TGN). In a Nordic/Baltic study the investigators have demonstrated higher levels of DNA-TGN during maintenance therapy in children with ALL that do not develop relapse (Nielsen et al. Lancet Oncol. 2017 Apr;18(4)). Preliminary studies indicate that the best approach to obtain DNA-TGN within a target range could be a combination of 6MP, MTX and 6-thioguanine (6TG), as 6TG more readily can be converted into TGN. This study aims to explore if individual dose titration of 6TG added to 6MP/MTX therapy can achieve DNA-TGN levels above a set target above 500 fmol/µg DNA, and thus can be integrated into future ALL and LBL treatment strategies to reduce relapse rates in ALL and LBL. The investigators plan to include 30 patients, and A) give incremental doses of 6TG until a mean DNA-TGN level above 500 fmol/µg DNA is obtained; and B) analyze the changes in DNA-TGN as well as cytosol levels of TGN and methylated 6MP metabolites (the latter inhibits purine de novo synthesis and thus enhance DNA-TGN incorporation), and C) occurrence of bone-marrow and liver toxicities during 6TG/6MP/MTX therapy.
The purpose of this study is to find the number of natural killer (NK) cells from non-HLA matched donors that can be safely infused into patients with cancer. NK cells are a form of lymphocytes that defend against cancer cells. NK cells in cancer patients do not work well to fight cancer. In this study, the NK cells are being donated by healthy individuals without cancer who are not "matched" by human leukocyte antigen (HLA) genes to patients. After receiving these NK cells, patients may also be given a drug called ALT803. ALT803 is a protein that keeps NK cells alive, helps them grow in number and supports their cancer-fighting characteristics. HLA-unmatched NK cell infusion is investigational (experimental) because the process has not approved by the Food and Drug Administration (FDA).
Acute lymphoblastic leukemia is the most common malignancy of the child. Current therapeutic strategies allow healing of over 80% of children. However these treatments are associated with toxicity, with a mortality of 1-2%. The most frequent complications, occuring during treatment initiation, are the thromboembolic complications. The most commonly accepted explanation is that of an anti-thrombin depletion by chemotherapy used in the treatment, L-asparaginase. But the anti-thrombin supplementation showed no efficacy in the prevention of these thromboembolic complications. Therefore most authors consider that a multifactorial mechanism is behind these events, involving both treatment and malignant cells. The interaction of these two factors participate in the damage of the vascular endothelium. The microparticles are membrane fragments derived from budding from the membrane of activated cells or apoptosis. Their thrombogenic role is linked to the expression of coagulation activators such as tissue factor. It is also associated with their role in the modulation of signaling pathways involved in the invasiveness and angiogenesis in endothelial cells. In acute lymphoblastic leukemia, the presence and role of microparticles have not been studied. Our hypothesis is that of production of microparticles upon lysis of blasts then upon activation of endothelial cells induced by the induction therapy, participating in a procoagulant phenotype.
This research trial studies the use of clinical practice guidelines by pediatric oncology healthcare providers in order to identify, understand, and overcome barriers to them. The treatments for childhood cancers are intense and result in a high rate of symptoms which require support by healthcare providers. By reviewing patients' medical chart records, meeting in focus groups and in one-on-one interviews, healthcare providers may improve how clinical practice guidelines are used to support children undergoing cancer treatment.
