Filter by:The purpose of this study is to find out if oral decitabine-cedazuridine (Inqovi®) is effective, safe, and able to be tolerated without severe side effects when given with thioguanine (Tabloid®) in patients with acute myeloid leukemia (AML) whose disease has returned or did not respond to treatment (relapsed or refractory). This is a "phase II trial with a safety lead-in." The goal of the lead-in portion of the study is to make sure participants are getting the highest dose of medications that are safe. If too many serious side effects are seen with the dose previously studied, some additional patients may be treated with a lower dose to make sure that this dose is safe.
Investigator proposed to apply the new dosage form of mitoxantrone hydrochloride liposomes to the clinical treatment of AML, while combining with cytarabine and azacitidine to form the MA+AZA treatment regimen(Mitoxantrone liposome +Ara-Cytarabine+Azacitidine), which would provide an optimal induction treatment regimen for patients with primary AML by comparing with the traditional chemotherapy regimen, DA+AZA (Daunorubicin+Ara-Cytarabine+Azacitidine).
This phase I trial tests the safety, side effects, and best dose of genetically engineered cells called EGFRt/19-28z/IL-12 CAR T cells, and to see how they work in treating patients with hematologic malignancies that makes a protein called CD19 (CD19-positive) that has come back after a period of improvement (relapsed) or that has not responded to previous treatment (refractory). Chimeric Antigen Receptor (CAR) T-cell Therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein on the patient's cancer cells is added to the T cells in the laboratory. The special receptor is called a chimeric antigen receptor (CAR). Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers. To improve the effectiveness of the modified T cells and to help the immune system fight cancer cells better, the modified T cells given in this study will include a gene that makes the T cells produce a cytokine (a molecule involved in signaling within the immune system) called interleukin-12 (IL-12). The researchers think that IL-12 may improve the effectiveness of the modified T cells, and it may also strengthen the immune system to fight cancer. Giving EGFRt/19-28z/IL-12 CAR T cells may be safe and tolerable in treating patients with relapsed or refractory CD19+ hematologic malignancies.
This is a single-center, open-label, non-randomized, two-arm, non-inferior trial. Patients with r/r B-ALL would be assigned to the CD19 CAR and CD22 CAR T-cell sequential infusion group (Sequential CAR, Arm-1) and the CD19 CAR T-cell infusion bridging to hematopoietic stem cell transplantation group (CAR+HSCT, Arm-2), according their own discretion. Patients would be also allowed to assigned to the CD19 CAR T-cell infusion without consolidation therapies group (Single CAR, additional placebo arm) according their own discretion. The primary objective is to prospectively evaluate and compare the efficacy of CD19 CAR and CD22 CAR T cell sequential infusions and CD19 CAR T-cell infusion bridging to HSCT in the treatment of r/r B-ALL. The primary endpoint is event-free survival of children and adolescent and young adult (AYA) with r/r B-ALL a treated with CD19 CAR and CD22 CAR T-cell sequential infusions and CD19 CAR T-cell infusion bridging to HSCT. A total number of 353 subjects will be enrolled.
B-ALL patients received regular follow-up after allogeneic hematopoietic stem cell transplantation, and in case of recurrence, they were given Blinatumomab. Anti-treatment was followed by DLI, and the second course was performed 1-2 months after DLI. Patients with positive MRD were treated with Blinatumomab 28μg×5-15 days, followed by DLI treatment. (MNC infusion is about 5×10^7/kg~1×10^8/kg). Patients with hematologic recurrence were given Blinatumomab 9μg D1-4,11.66μg d5-7,28μg Starting from d8 （8 to 21 days in total）, followed by DLI treatment (infusion of MNC approximately 5×10^7/kg~1×10^8/kg). Objective To observe and analyze the efficacy and side effects of Blinatumomab followed by donor lymphocyte infusion in patients with relapsed acute B lymphoblastic leukemia after allogeneic hematopoietic stem cell transplantation in our hospital.
Chemotherapy, the main treatment for childhood leukemia, has side effects on healthy cells. One of the most important of these side effects is the risk of infection due to neutropenia. In clinics, blood culture is the gold standard for the detection of possible infection risk (bacteremia, fungemia, etc.). During the diagnosis and treatment process in children with leukemia, a large number of peripheral or catheter blood cultures are performed. When the culture results are positive, it is accepted that the infection has grown. In some cases, a positive peripheral blood culture result may not be clinically significant. An agent belonging to the skin flora of the patient or the healthcare professional taking the field culture may also cause the blood culture result to be positive. This is called contamination or false positive blood culture. Contaminated cultures may cause prolonged hospitalization, additional medical interventions, unnecessary initiation of antibiotic treatment and related antibiotic resistance, toxicity due to additional drugs and an increase in hospital costs. The peripheral blood culture contamination rate, which is accepted as a quality indicator in some countries, should be below 3%. In this context, this study aimed to determine the prevalence of false positive peripheral blood cultures by examining the peripheral blood culture results obtained during routine follow-ups from children hospitalized with leukemia in the pediatric hematology clinic. The data will be collected retrospectively covering three years before March 2024 when the ethics committee approval was obtained. Since the relevant clinic cares for approximately 25 new children diagnosed with leukemia annually, the study sample is planned as 75 cases.
The primary objective of this trial is to improve the overall survival rate of children and young adult with B-lineage acute lymphoblastic leukemia (B-ALL) in Singapore and Malaysia in the context of a multicenter cooperative trial using a risk-stratified therapy.
Patients eligible undergoing total body irradiation as candidates for bone marrow or peripheral stem cell transplant.
Long non-coding RNAs (lncRNAs) are a class of biomarkers of crescent interest in the hematologic and oncologic field. They do not encode proteins and can alter gene expression by acting on different steps of regulation, including DNA methylation and chromatin structure. Recent data identified recurrent somatic alterations in genes involved in DNA methylation and post-translational histone modifications in T-ALL, suggesting that epigenetic homeostasis is critically required in restraining tumor development in the T-cell lineage. Further, recent studies showed that the expression levels of specific lncRNAs correlate with the prognosis of patients with Acute Lymphoblastic Leukemia of T-cells (T-ALL). The objectives of this research project are to identify T-ALL-specific lncRNAs to be used as new diagnostic and prognostic biomarkers of disease and to explore their role on chromatin reorganization and transcriptional regulation that may lead to the onset and progression of T-ALL.
This study will evaluate fixed-duration therapy with pirtobrutinib and obinutuzumab given over 12 cycles (approximately 1 year) as first-line treatment of chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL or SLL).
