Chimeric Antigen Receptor T Cell Therapy for Acute Myeloid Leukemiachimeric Antigen Receptor T Cell Therapy for Acute Myeloid Leukemia

Relapse of leukemic cells that do not express the antigen targeted by chimeric antigen receptor (CAR) is still a risk. As is the potential for targeting hematopoietic stem cells (HSCs) that share the same antigen expression, off-tumor on-target toxicity. Further, CAR T cells that bind different epitopes of the same antigen can have different tumor-killing efficacies. Therefore, we screen murine single chain variable fragment (scFv) based for indirect affinity to identify a CAR that targets Acute myeloid leukemia (AML), while minimizing toxicities.

Pediatric myelodysplastic syndromes (MDS) represent a spectrum of rare hematopoietic stem cell disorders characterized by cytopenias, ineffective hematopoiesis, marrow dysplasia and risk for leukemic transformation. While some cases are likely acquired due to de novo transformation, germline mutations in DNA repair pathways, ribosomal pathways, the telomere complex or in hematopoietic transcription factors (e.g., CEBPA, RUNX1, GATA2 and ETV6) are predisposition syndromes underlying many pediatric cases of MDS and acute myeloid leukemia (AML).

ConclusionT2B2F is associated with a higher incidence of acute GVHD compared with T1B2F. These results suggest that a lower dose-intensity of thiotepa and busulfan in the TBF regimen may yield better results in patients with AML in CR.

Authors: Gorshein E, Weber UM, Gore S Abstract Introduction: Myelodysplastic Syndrome (MDS) represents a group of cancers characterized by abnormal blood cell formation and maturation, leading to various degrees of cytopenias and potential transformation to acute myeloid leukemia. Deletion of the long arm of chromosome 5 (del(5q)) is the most common clonal chromosomal anomaly in MDS, yet the population in this disease subtype is quite heterogeneous. This manuscript analyzes literature on high-risk MDS with del(5q) abnormalities.Areas covered: The paper will review outcomes with lenalidomide among high-risk MDS pati...

Standardized phase angle (SPhA) is a tool used to estimate body composition and cell membrane integrity. Lower baseline SPhA was associated with increased incidence of 60 ‐day mortality in univariable (odds ratio [OR] = 5.25; 1.35, 20.44;P = .02) but not multivariable analysis (OR = 3.12; 0.67, 14.48;P = .15) adjusted for age, creatinine, and cytogenetics. Standardized phase angle is a rapid, noninvasive, and objective measure that may be used to inform risk stratification in adult acute leukemia patients. AbstractStandardized phase angle (SPhA) is a tool used to estimate body comp...

AbstractPurpose of ReviewThis review discusses the current standard of care for incorporation of FLT3 TKIs and HCT into the treatment of FLT3-ITD AML. Additionally, this review provides an approach to the patient with relapsed/refractory disease.Recent FindingsOver the last decade, the routine use of HCT as consolidative therapy and the development of FLT3 TKIs have significantly improved remission rates and overall survival. The value and challenges of MRD assessment in FLT3 disease are discussed and current mechanisms of relapse are explored, as are the ongoing questions in the field that current clinical trials are seek...

Abstract New therapeutic strategies are needed for pediatric acute myeloid leukemia to reduce disease recurrence and treatment-related morbidity. The Children's Oncology Group Phase III AAML1031 trial tested whether the addition of bortezomib to standard chemotherapy improves survival in pediatric patients with newly diagnosed acute myeloid leukemia. AAML1031 randomized patients younger than 30 years of age with de novo acute myeloid leukemia to standard treatment with or without bortezomib. All patients received the identical chemotherapy backbone with either four intensive chemotherapy courses or three courses f...

Conclusions Our results suggest that giving levetiracetam at 1000  mg q12h p.o starting 12 h before the administration of i.v. busulfan until 48 h after the last dose, can be used as an alternative in the prevention of busulfan-induced seizures in adults.

Luo, Weiping Yuan, Xiaomin WangAbstractEnhanced interleukin-1β (IL-1β) signaling is a common event in patients with acute myeloid leukemia (AML). It was previously demonstrated that chronic IL-1β exposure severely impaired hematopoietic stem cell (HSC) self-renewal capability in mice and promoted leukemia cell growth in primary AML cells. However, the role of IL-1β in the murine bone marrow (BM) niche remains unclear. He...

The graft versus leukemia effect, driven by donor T cells, plays a major role in its curative potential. This effect is sometimes very evident when patients with acute myeloid leukemia and myelodysplasi...
