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).
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.

No additional efficacy or safety data has been requested.
Mutations in fms-related receptor tyrosine kinase 3 (FLT3) are related to the increase of reactive oxygen species (ROS) in acute myeloid leukemia (AML). Recent studies suggest that by regulating ROS production and antioxidant expression, oncogenes such as FLT3 directly influence leukemia progression, even during anticancer therapy.
