Abstract published as part of the American Society of Hematology (ASH) Annual MeetingStudy shows Annamycin effectively targets both Cytarabine (Ara-C) and Venetoclax resistant acute myeloid leukemia (AML) cell lines from heavily pretreated relapsed/refractory primary AML patients in vitroLack of apparent cardiotoxicity, improved organotropism, synergy with Ara-C, and possible immune-memory reinforcing properties appear to contribute to the favorable performance of Annamycin in clinical settingsSuch preclini ...
