Part of the reason for CAR T cells’ astonishing success in B-cell cancers is that B cells are astonishingly easy to replace. CAR T cells are specific, yes. But they are not specific to tumor cells. They are specific to their target antigens. In the case of Yescarta (axicabtagene ciloleucel, Gilead Sciences Inc.) and Kymriah (tisagenlecleucel, Novartis AG), the first two clinically approved T cells, that target is CD19, which is expressed on B-cell precursors. And when it is successful, the treatment leaves patients without any B cells at all.
Researchers from City of Hope discussed preclinical data for CD33-targeted chimeric antigen receptor (CAR) T cells being developed for the treatment of acute myeloid leukemia (AML).
Researchers from Wenzhou Medical University and affiliated organizations have published data from a study that aimed to investigate the relationship between the tumor suppressor microRNA-143 (miR-143) and RNA-binding protein Musashi homolog 2 (MSI2), the abnormal expression of which has been previously associated with cancer progression.
It was previously shown that AXL overexpression is associated with poor prognosis, metastasis, as well as drug resistance in various hematological and solid tumors, and that inhibition of AXL phosphorylation could overcome drug resistance to FLT3 inhibitors. CTS-2016 is an AXL/FLT3 inhibitor being developed by Cytosinlab Therapeutics Co. Ltd. as a novel tyrosine kinase inhibitor for cancer.
Although FMS-like tyrosine kinase 3 (FLT3) inhibitors have shown success treating FLT3-mutated acute myeloid leukemia (AML), around 30% to 50% of patients show primary resistance to both type I and type II inhibitors. Therefore, identifying therapeutic strategies to overcome this resistance and enhance the efficacy of FLT3 inhibitors remains an urgent need.
Daiichi Sankyo Co Ltd. has experienced yet another setback with its quizartinib NDA submission, as the U.S. FDA has now extended the review period by three months to July 24, 2023, to allow additional time to review requested updates to the proposed Risk Evaluation and Mitigation Strategies.
