Mark Levis, MD, PhD, Sidney Kimmel Comprehensive Cancer Center, Baltimore, MD, discusses using a combination therapy of bromodomain and extraterminal protein (BET) inhibitors and FMS-like tyrosine kinase 3 (FLT3) inhibitors to treat patients with FLT3 internal tandem duplication (FLT3-ITD)-mutated acute myeloid leukemia (AML). Dr Levis discusses how the difficulties of killing leukemic cells in the bone marrow microenvironment led to the development of this combination therapy in vitro. Promising in vitro results support the proposal that this combination therapy may be effective in clinical trials. This interview took place at the virtual European Hematology Association (EHA) Congress 2021.
