About MGD006

MGD006 is a humanized DART molecule that recognizes both CD123 and CD3. The molecule was designed to redirect T cells via their CD3 component to kill CD123-expressing cells, as shown pre-clinically. CD123, the Interleukin-3 receptor alpha chain, has been reported to be overexpressed on malignant cells in a wide range of hematological malignancies including acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). AML and MDS are thought to arise from a small population of leukemic stem cells (LSCs) that generally resist conventional chemotherapeutic agents. LSCs are characterized by high levels of CD123 expression that is low or absent in the corresponding normal hematopoietic stem cell population. This product candidate is currently being tested in a Phase 1 clinical study in patients with relapsed or refractory AML.
