Slide 16: Why We are Targeting CD123
Why We are Targeting CD123 CD123 (an IL3 receptor which creates an anchor for our unique CD3) is an antigen that is overexpressed in AML and MDS cells which makes this a meaningful therapeutic target CD123 is also expressed on leukemic stem cells (LSCs), which are self-renewing, making them resistan
