HDAC8 inhibition targets STAT3-MYC axis and synergizes with Venetoclax in KMT2A-rearranged acute myeloid leukemia

Blocking a specific protein in aggressive leukemia cells restored sensitivity to a modern therapy regardless of mutation status, suggesting a new drug combination worth testing in trials.

HDAC8 is upregulated in KMT2A-rearranged AML and its inhibition degrades STAT3 via acetylation, suppressing MYC and overcoming Venetoclax resistance regardless of TP53 status. HDAC8 inhibitor combination with Venetoclax demonstrated synergistic anti-leukemia activity in primary AML cells, mouse models, and PDX, providing preclinical rationale for clinical trial development in this poor-prognosis AML subtype.

What the study was

Study design
Preclinical (KMT2A::MLLT3 mouse model + PDX + primary AML cells)
Population
KMT2A-rearranged AML (mouse model, PDX, primary patient cells)
Category
Drug Development
Maturity
Exploratory
Journal
Leukemia

Why it surfaced

Promising TP53-status-independent Venetoclax sensitization in KMT2A-r AML addresses high unmet need; Leukemia journal peer review; PDX validation strengthens translational potential; capped at 5 for preclinical.
