Overview

**APG-115 + cytarabine** is an investigational drug combination consisting of APG-115, a novel, orally active small-molecule inhibitor of mouse double minute 2 homolog (MDM2), and cytarabine, a pyrimidine nucleoside analog chemotherapeutic. APG-115 blocks the interaction between MDM2 and p53, thereby activating the p53-mediated apoptosis pathway, inducing cell cycle arrest, and inhibiting proliferation of tumor cells in acute myeloid leukemia (AML). Cytarabine induces DNA damage and activates the ATM/ATR-p53/p21 signaling cascade, contributing to cell cycle arrest and apoptosis. When used together, APG-115 + cytarabine has shown synergistic antileukemic activity, significantly enhancing apoptosis and inhibiting cellular growth, especially in TP53 wild-type AML models. This combination is undergoing clinical investigation for relapsed/refractory AML and myelodysplastic syndromes (MDS)[1][3][4][7][9].
