    Current status and future potential of CD123-based targeted therapies for acute leukemia. (PubMed, Expert Opin Biol Ther)
    It discusses completed and ongoing clinical trials for agents such as tagraxofusp, pivekimab sunirine, flotetuzumab, vibecotamab, and investigational CAR T-cell therapies (e.g. MB-102, UCART123v1.2). While clinical activity has been demonstrated, especially in BPDCN, therapeutic durability and safety remain hurdles. Precision in antigen targeting, combination strategies, and toxicity management will be critical for successful integration of CD123-directed therapies into standard clinical practice.

    Bispecific CD33/CD123 targeted chimeric antigen receptor T cells for the treatment of acute myeloid leukemia. (PubMed, Mol Ther Oncolytics)
    The CD33/CD123 bispecific CAR T cells were able to control acute myeloid leukemia (AML) in a xenograft AML mouse model similar to monospecific CD33 and CD123 CAR T cells while showing no on-target off-tumor effects. Based on our findings, human CD33/CD123 bispecific CAR T cells are a promising cell-based approach to prevent AML and support clinical investigation.

    Significantly Targeting Acute Myeloid Leukemia with the Combination of Anti-CD123 CAR Modified Expanded Natural Killer Cells and Romidepsin (TCT-ASTCT-CIBMTR 2023)
    Results Anti-CD123 CAR expressed on more than 96% of expanded NK cells after CAR mRNA electroporation (Fig.1A) and lasted for about one week. Anti-CD123 CAR NK showed significantly enhanced in vitro cytotoxicity against CD123 + KG1a and HL-60 with significantly enhanced IFN-
