Management of Acute Myeloid Leukemia: A Review

Background/Objectives: Acute myeloid leukemia (AML) is a heterogeneous hematologic malignancy with historically poor outcomes, particularly among older adults and patients harboring high-risk molecular features. Advances in genomic profiling have enabled the development of targeted therapies, reshaping treatment algorithms beyond conventional cytarabine-anthracycline induction and hypomethylating agent-based regimens. This review summarizes current evidence and emerging therapeutic strategies across four evolving areas: menin inhibition, FLT3 inhibition, IDH inhibition and treatment approaches for TP53-mutated AML. Methods: We reviewed published clinical trials, preclinical studies, and ongoing clinical trials evaluating targeted therapies in AML. Emphasis was placed on agents with regulatory approval or substantial clinical development, including menin inhibitors, FLT3 inhibitors, IDH inhibitors and novel therapies directed at TP53-mutated disease. Mechanistic data, response rates, survival outcomes, and resistance patterns were analyzed to provide an updated overview of therapeutic progress. Results: Menin inhibitors have demonstrated significant activity in NPM1-mutated and KMT2A-rearranged AML, with agents such as revumenib and ziftomenib producing meaningful remission rates and ongoing studies exploring combination strategies to mitigate resistance. FLT3 inhibitors, including midostaurin, gilteritinib, and quizartinib, have improved survival in FLT3-mutated AML, while emerging evidence supports potential benefit in selected FLT3–wild-type disease based on FLT3-like gene expression signatures. IDH inhibitors, namely ivosidenib and enasidenib, have provided increased efficacy in AML patients carrying these mutations. Questions still remain regarding their efficacy in contrast to venetoclax which has been shown to be particularly effective against this population. In contrast, TP53-mutated AML remains a therapeutic challenge: although hypomethylating-agent/venetoclax-based regimens yield improved initial responses, remissions are generally short-lived and overall survival remains poor. Early-phase therapies, including p53 reactivators and multi-kinase inhibitors, show preclinical promise but lack definitive clinical efficacy to date. Conclusions: Targeted therapies have improved outcomes in molecularly defined subsets of AML, with menin, IDH and FLT3 inhibitors representing major advances. However, TP53-mutated AML continues to carry a dismal prognosis, underscoring the need for more effective therapeutic strategies. Continued biomarker-driven research, novel drug combinations, and mechanistic insights will be essential to further refine AML treatment and improve long-term survival across disease subsets.
