Active clinical trials for "Precursor Cell Lymphoblastic Leukemia-Lymphoma"

The overall objective of this study is to continue to improve the cure rate of childhood acute lymphoblastic leukemia (ALL) in Singapore and Malaysia in the context of a multi-centre cooperative trial using a risk-stratified therapy based primarily on early response to therapy utilizing a simplified minimal residual disease (MRD-lite) platform.

This study aims to evaluate the safety and clinical activity of CD19 Chimeric Antigen Receptor (CAR) redirected autologous T-cells in treating patients with recurrent or refractory CD19 positive B cell ccute lymphoblastic leukemia,and dynamically observe the changes of CAR-T in patients and the residual tumor.

This phase 1 / 2 study will evaluate the response of B-cell malignancies expressing CD19 to autologous T cells transduced with a second generation anti-CD19 chimeric antigen receptor in children and young adults.

This is a single arm, open-label, multi-center study to determine the efficacy and safety of an experimental therapy called CART-19 in patients with chemo-refractory and relapsed B-cell ALL.

This is a single-arm open-label phase I/II study to determine the relative superiority of αCD19-TCRζ-CD28 and αCD19-TCRζ-CD137 CAR-T Cells in safety, efficacy and engraftment potential in patients with CD19+ B-lineage leukemia and lymphoma. Recently, cancer immunotherapy, treatments aiming to arm patients with immunity specifically against cancer cells, has emerged as a promising therapeutic strategy. Clinical trials utilizing CARs against B cell malignancies have demonstrated remarkable potential. In this trial, all subjects will be competitively infused with αCD19-TCRz-CD28 and αCD19-TCRz-CD137 CAR-T cells in equal number to test a hypothesis that CD137-costimulation can promote the persistence and engraftment of CAR-T cells and this superiority can lead to improved progression-free survival.

The purpose of this study was to assess the efficacy and safety of individualized treatment of 6-mercaptopurine (6-MP) in Chinese children with acute lymphoblastic leukemia, and to investigate the dose-concentration-response (DER) relationship between thiopurine metabolites and adverse events. The individualized administration of 6-MP was established in Chinese children with acute lymphoblastic leukemia.

This is an open, single-arm, phase I/phase II clinical study to evaluate efficacy and safety of chimeric antigen receptor T cell immunotherapy (CAR-T) in the treatment of Relapsed Refractory (R/R) adult acute lymphoblastic leukemia bridging allogeneic hematopoietic stem cell transplantation.

In this study, CAR-T will be administered to children with acute lymphoblastic leukemia to explore the effect of CAR-T intervention time on the duration of complete remission and further verify the long-term safety and efficacy of CAR-T treatment.

Constipation is the most common complaint in childhood, affecting an estimated 20% of children globally. At present, the treatment of children's constipation is full of challenges, and treatment methods are diverse. Studies have shown that pelvic floor dysfunction is a common cause of intractable constipation in children. Zhang et al. have confirmed the role of pelvic floor dysfunction in pediatric constipation. At present, the main methods for pelvic floor dysfunction include surface electromyography and anorectal manometry which have been widely used in children with constipation and they are helpful for the diagnosis of pelvic floor dysfunction in children with constipation. Sacral nerve electrical stimulation combined with pelvic floor rehabilitation is an effective method for the treatment of pelvic floor dysfunction. It offers a novel approach for the treatment of intractable constipation with pelvic floor dysfunction . At present, there are many methods for sacral nerve regulation. Percutaneous tibial nerve stimulation (PTNS), another peripheral nerve electrical stimulation approved by the United States Food and Drug Administration, has the same effect as sacral nerve regulation, and has the advantages of small trauma, safety, and convenience. However, there is still a lack of evidence-based support for the treatment of childhood constipation by PTNS combine with PFR. Therefore, in this study, a randomized, controlled, double-blind clinical trial was designed to confirm the efficacy and safety of PTNS combine with PFR in the treatment of childhood constipation.

Phase I was a single arm, open label, dose increasing study to explore the safety, tolerance and Cytodynamic characteristics of the drug, and to preliminarily observe the efficacy of the study drug in relapsed / refractory CD7 Positive hematolymph system malignant tumor patients, so as to explore the clinical applicable dose of phase II. Since the activity and toxicity of cellular drugs (long-term survival drugs) do not have obvious dose dependence, and the increase of their dose may be accompanied by the increase of toxicity, rather than necessary for therapeutic effect, it is not necessarily suitable to recommend the effective dose according to the maximum tolerable dose (MTD). Therefore, this study will be based on the safety data, as well as the preliminary efficacy, efficacy and drug The end point of pharmacokinetics (ORR, the content of CD7 Positive Cells, the expansion and duration of car-t cells) were comprehensively considered to determine the recommended dose for phase II clinical trial.Main research purposes Objective to evaluate the safety and tolerability of T cell injection targeting CD7 autologous chimeric antigen receptor in the treatment of relapsed / refractory CD7 Positive hematological and lymphoid malignancies.
