ABSTRACT
Introduction
Acute myeloid leukemia (AML) is a heterogeneous disease characterized by many cytogenetic and molecular alterations. Due to better knowledge of the molecular basis of AML, many targeted therapies have been introduced and registered, e.g. FMS-like tyrosine kinase 3 inhibitors, isocitrate dehydrogenase 1/2 mutation inhibitors, and Bcl-2 inhibitor. Despite that, the cure for AML remains an unmet clinical need in most patients.
Areas covered
The review aims to present new, not yet registered drugs for AML. We searched the English literature for articles concerning AML, targeted drugs, menin inhibitors, DOT1L, BET, IDH inhibitors, FLT3, hedgehog inhibitors, Polo-like kinase inhibitors, RNA splicing, and immune therapies via PubMed. Publications from January 2000 to August 2022 were scrutinized. Additional relevant publications were obtained by reviewing the references from the chosen articles and Google search. Conference proceedings from the previous 5 years of The American Society of Hematology, the European Hematology Association, and the American Society of Clinical Oncology were searched manually. Additional relevant publications were obtained by reviewing the references.
Expert opinion
For several years, the therapeutic approach in AML has become more individualized. Novel groups of drugs give hope for greater curability. High response rates have agents that restore the activity of the p53 protein. In addition, agents that work independently of a particular mutation seem promising for AML without any known mutation.
Article highlights
Along with a better understanding of the molecular basis of AML, it became possible to introduce targeted therapies
New targeted therapies include menin inhibitors, DOT1L inhibitors, BET inhibitors
A completely new strategy considers drugs targeting RA splicing that comprises splicing modulators and IRAK4 inhibitors
Immune therapy in AML is not as effective as in lymphomas, mainly due to the heterogeneity of the disease and the lack of a specific antigen
Future directions of the development of already registered drugs are assessing their role in new combinations and the development of next-generation molecules
This box summarizes the key points contained in the article.
