Study of the Medullary Microenvironment in Acute Childhood Leukemia

Acute leukemia (AL) is the most common cancer in children. Despite the optimization of chemotherapy treatments and the development of supportive care, a certain number of LAs relapse and/or progress to death of the child. It therefore seems essential to try to better understand the physiopathology and the mechanisms of resistance to treatment of these diseases.

CHIP-AML22/Quizartinib: Quizartinib + Chemotherapy in Newly Diagnosed Pediatric FLT3-ITD+ and NPM1wt AML Patients

The CHIP-AML22 Master protocol has the overall aim of increasing the cure rate in newly diagnosed pediatric de novo AML patients, while avoiding unnecessary toxicity. The linked Quizartinib trial (CHIP-AML22/Quizartinib) is a phase II, single arm, open label, study on the safety, efficacy, pharmacokinetics and pharmacodynamics of quizartinib in combination with chemotherapy and as single-agent after high dose therapy in newly diagnosed pediatric AML patients with a FLT3-ITD mutation and NPM1 wild-type.

CHIP-AML22/Master: An Open Label Complex Clinical Trial in Newly Diagnosed Pediatric de Novo AML Patients

The CHIP-AML22 Master protocol has the overall aim of increasing the cure rate in newly diagnosed pediatric de novo AML patients, while avoiding unnecessary toxicity.

Brain MRF in Children, Adolescents and Young Adults With Acute Leukemia

The survival of children, adolescents and young adults (AYA) with acute leukemia has improved dramatically over the last two decades. This success is a result of using multiple chemotherapy drugs in combination, with the inclusion of drugs that enter the brain and prevent leukemia cells from growing there. Studies in these cancer survivors have shown that the exposure to these chemotherapy drugs can lead to risks for impaired brain function, also referred to as neurocognitive side effects of chemotherapy. There is an opportunity to identify participants at risk for these side effects and to prevent their development. The purpose of this study is to incorporate a brain imaging tool known as Magnetic Resonance Fingerprinting (MRF) to look for brain matter changes in acute leukemia participants receiving chemotherapy. The MRF scan will be performed at diagnosis and repeated at multiple times during the entire therapy duration as well as at defined intervals after therapy is complete. Investigators would also do an electronic test of memory and brain function (cognitive function), which would be administered in a gaming format on iPads or a similar device. The goal will be to correlate results of MRF imaging with the tests of cognitive function. The benefits of this imaging technique include that it can be done quickly (in minutes), it is non-invasive, it is resistant to motion-artifacts and it can be easily repeated for comparison purposes. The advantages of the cognitive test include its short duration of 20 minutes and its gaming format making it friendly for children to use.

Individualized Treatment of Pediatric R/R AML Based on Transcriptomic Profile and in Vitro Drug Sensitivity Test

Acute myeloid leukemia (AML) accounts for about 15% to 20% of childhood leukemia, but the death rate accounts for about 50%. About 20-30% of children with AML did not achieve complete response (CR) after 2 induction treatments, and about 30% of children with CR had relapse within 3 years (including recurrence after hematopoietic stem cell transplantation).Relapsed/refractory (R/R) AML is a major cause of treatment failure and refractory survival. Reinduction chemotherapy for R/R-AML to obtain CR again, followed by hematopoietic stem cell transplantation, is the current treatment. At present, there is no recognized reinduction protocol, and the reinduction remission rate of R/R-AML varies greatly among different treatment regimens, ranging from 23 to 81%. Current guidelines recommend a new combination chemotherapy regimen consisting of new drugs without cross-resistance. This method selects sensitive chemotherapeutic drugs, and then forms a new combination chemotherapy regimen according to the characteristics of drugs, which is the choice of R/R-AML reinduction therapy.This study intends to conduct a clinical study on the individualized treatment of R/R AML patients through in vitro drug sensitivity test combined with patient transcriptomic characteristics.
