Abstract
- We have recently shown that bone marrow (BM) RNA profiles stratify patients with acute myeloid leukemia (AML) into immune-infiltrated and immune-depleted subtypes and that type I/II interferon (IFN)-related gene signatures associate with complete response to flotetuzumab (FLZ), an investigational CD123×CD3 bispecific DART molecule. Within the AML tumor microenvironment CD8+T cells exhibit features of immune exhaustion and senescence (IES). IES are dysfunctional states driven by metabolic alterations in the tumor microenvironment (TME) and emerging targets for cancer immunotherapy. The aim of the current study was to determine whether IES predicts response of relapsed-refractory (R/R) AML to FLZ in the CP-MGD006-01 clinical trial.
