Active clinical trials for "Leukemia"

Extension study to provide ongoing long-term treatment with ASTX727 for participants who were benefitting from ASTX727 treatment in a previous Astex-sponsored clinical study of ASTX727 (including, but not limited to ASTX727-01 [NCT02103478], ASTX727-02 [NCT03306264], ASTX727-04 [NCT03813186]), and Food Effect Substudy to obtain survival information and long-term safety information. The purpose of the Food Effect Substudy is to evaluate the pharmacokinetics (PK) and safety of decitabine and cedazuridine when ASTX727 is given under fed (high-calorie/high-fat meal or low-calorie/low-fat meal) versus fasted conditions.

This randomized clinical trial will evaluate two approaches of GvHD prophylaxis; the standard of care GVHD prophylaxis regimen (methotrexate/calcineurin inhibitors) and post-transplant cyclophosphamide with calcineurin inhibitors for their efficacy as a new GVHD prophylaxis strategy.

The purpose of this study is to evaluate the efficacy of supplementation with Omega 3, Vitamin D and Calcium, in a cohort of children with ALL undergoing treatment and compare changes in the concentrations of biomarkers of bone resorption (TRAP5b, CTX, and RANKL), the RANKL/OPG ratio, and biomarkers of bone formation (BALP, OC, PINP, PICP and OPG) after 6 and 12 weeks of supplementation.

The purpose of this study is to examine a psychotherapeutic and psycho-educational intervention offered in virtual settings to caregivers of youth with cancer. Human subjects must be used because they are the object of the intervention.

A single-arm, non-randomized four-month trial of the adapted family-based behavioral weight loss treatment (FBT) intervention will be conducted to evaluate its acceptability, feasibility, and preliminary indications of efficacy including measures of relative weight change and associated secondary outcomes (e.g., weight related health behaviors, health related quality of life), among 40 childhood acute lymphoblastic leukemia (ALL) survivors and their families.

The goal of this feasibility study is to determine if Virtual Reality (VR) can be adequately used as an alternative to General Anesthesia (GA) for Lumbar Punctures (LP).

CiproPAL is a randomised trial comparing daily ciprofloxacin with local standard care during the induction phase of paediatric ALL treatment, and aims: To assess the efficacy of ciprofloxacin prophylaxis in the reduction of infection during the induction phase of treatment for paediatric Acute Lymphoblastic Leukaemia within the ALLTogether-1 Trial. To evaluate the impact of ciprofloxacin prophylaxis on antimicrobial resistance, both of invasive infections and colonising organisms.

The aim of this study is to evaluate the feasibility of a digital health coaching program for, and to describe quality of life of, individuals in the 6 months following chimeric antigen receptor (CAR) T cell therapy. Up to 50 English-speaking individuals aged 18 and older who are to receive treatment with a CAR T cell therapy will be enrolled, all at The University of Texas MD Anderson Cancer Center. Participants must have internet access via smart phone, tablet, a computer, or another device with the capacity to receive calls, texts, or e-mails, as well as the electronic study assessments and will be excluded if they are unable to provide informed consent or have a prognosis of 6 months or less. Consented participants will be enrolled in a 6-month digital health coaching program delivered via weekly calls from a Health Advisor coupled with the digital delivery of content. The program focuses on identification and escalation of treatment-related toxicity, communication with providers, and physical and psychosocial health following treatment. Health related quality of life (HRQoL) will be assessed with the Functional Assessment of Cancer Therapy-Lymphoma (FACT-L), health self-efficacy will be assessed by the Cancer Behavior Inventory-Brief (CBI-B), physical and mental health outcomes will be measured by the National Institutes of Health (NIH) Patient Reported Outcomes Measurement Information System (PROMIS) Global Health 10. Patient experience in managing CAR T specific care will be assessed with a 5-item questionnaire developed specifically for use in this study, focused on participants' confidence in understanding, identifying and managing symptoms, and communicating with providers. Study outcomes will contribute to knowledge about if and how a digital health intervention may be used to support individuals post-CAR T cell therapy.

Among its authorized indications, posaconazole (PCZ) is prescribed for prophylaxis in onco-hematology patients at high risk of invasive fungal infections. This azole antifungal has a low bioavailability. The enteric-coated tablets form available since mid-2015 has significantly improved its pharmacokinetic profile compared to the oral suspension form initially used. According to the recommendations of The European Conference on Infections in Leukemia (ECIL-6), the minimum serum concentration desirable for prophylaxis is 0.7 mg/L. This concentration threshold was difficult to achieve in onco-hematology patients treated with oral suspension. The investigators retrospectively collected and analyzed 201 results of residual PCZ serum concentrations from 91 onco-hematology patients on Noxafil® tablets prophylaxis. The median concentration of PCZ was 1.08 mg/L. In this study, the pharmacokinetics of tablet-PCZ showed significant inter-individual variability. Thus, while 25% of the concentrations remained below the recommended threshold of 0.7 mg/L (25% percentile = 0.69 mg/L), exposure to PCZ was greater than 2.63 mg/L in 10% of cases. This level of exposure, however, did not have obvious hepatic repercussions. Nevertheless, further studies involving larger cohorts are needed to clarify a hypothetical relationship between serum PCZ concentration and the occurrence of hepatic toxicity. In addition, the investigators found significant intra-individual variability in PCZ exposure (CV = 48.8%), especially in leukemic patients. This variability is probably related to a modification during the treatment of the physio-pathological conditions of the patient likely to impact the pharmacokinetics of PCZ (absorption, distribution, metabolism, etc.) as well as the effect of possible pharmacokinetic drug interactions. The metabolism of PCZ is mediated primarily by the uridine diphosphate (UDP)-glucuronosyltransferase 1A4 (UGT1A4) pathway. Although hepatic metabolism of PCZ is low compared with other azoles (such as itraconazole or voriconazole), differences in the metabolic capacity of UGT1A4 may alter PCZ exposure. A previous study of the oral suspension form had shown that low concentrations of PCZ were associated with a high ratio of PCZ-glucuronide / PCZ concentrations. Two genetic variants of the gene encoding UGT1A4 are associated with a decrease in the metabolic clearance of glucuronide drugs via UGT1A4. A recent study suggests less exposure to PCZ in the presence of UGT1A4 polymorphism. The main objective of the investigator's project is to study prospectively in a homogeneous population of patients treated by intensive chemotherapy for acute myeloid leukemia (induction and consolidation) the pharmacokinetics of PCZ administered in its tablet formulation, and in particular: Clinical and biological tolerance of high concentrations of PCZ The influence of clinical and demographic covariates on PCZ and PCZ-glucuronide ratio The influence of genetic variants of UGT1A4 on PCZ metabolism (PCZ-glucuronide / PCZ ratio).

Metabolic reprogramming has been identified as a hallmark of cancer. Almost a century after Otto Warburg initially discovered increased glycolytic activity in tumor tissue ("Warburg effect"), therapeutic targeting of cancer metabolism has become a field of intense research effort in cancer biology. A growing appreciation of metabolic heterogeneity and complexity is currently reshaping investigators "simplistic" understanding of metabolic reprogramming in cancer. Discovering metabolic vulnerabilities as new treatment targets for cancer requires systematic dissection of metabolic dependencies, fuel preferences, and underlying mechanisms in the specific physiological context. However, today's data on cancer cell metabolic signatures and heterogeneity in their physiological habitat of the human organism is sparse to non-existent representing a critical knowledge gap in designing effective metabolic therapies. Here, the investigators propose a "top-down" approach studying cancer cell metabolism in patients followed by mechanistic in-depth studies in cell culture and animal models to define metabolic vulnerabilities. Investigators will develop a metabolic tracing method to quantitatively characterize metabolic signatures and fuel preferences of leukemic lymphocytes in patients with chronic lymphocytic leukemia (CLL). Isotopic metabolic tracers are nutrients that are chemically identical to the native nutrient. Incorporated stable, non-radioactive isotopes allow investigators to follow their metabolic fate by monitoring conversion of tracer nutrients into downstream metabolites using cutting-edge metabolomics analysis. Using this method, investigators propose to test the hypothesis that leukemic lymphocytes show tissue-specific metabolic preferences that differ from non-leukemic lymphocytes and that ex vivo in-plasma labeling represents a useful model for assaying metabolic activity in leukemic cells in a patient-specific manner.
