[Future prospects for the development of novel agents for acute myeloid leukemia]

For nearly 40 years, combination therapy with cytarabine and anthracycline has been the standard of care for acute myeloid leukemia (AML). The cytogenetics and molecular biology of AML are now understood, and the treatment of AML has undergone dramatic changes in Japan with the launch of drugs such as FLT3 inhibitors, Bcl2 inhibitors, and hypomethylating agents since 2018. However, AML remains very difficult to cure, with a high relapse rate. Here, we review novel agents that have not yet been approved in Japan (CPX-351, IDH inhibitors, menin inhibitors, and oral azacitidine) as potential treatments for AML, as well as therapeutic antibodies (BiTEs, DARTs, immune checkpoint inhibitors) currently under investigation in clinical trials or in development. These novel agents are being investigated not only as monotherapy but also as combination therapy with intensive chemotherapy or azacitidine/venetoclax. The new era of AML treatment is expected to support a variety of goals, including leukemic cell elimination, long-term remission, and improved quality of life.
