Therapies for acute myeloid leukemia in patients ineligible for standard induction chemotherapy: a systematic review

Aim: To review clinical evidence for current and emerging treatments for patients with acute myeloid leukemia (AML) who are ineligible for first-line induction chemotherapy. Methods: A systematic literature review was performed (28 October 2021) to identify clinical outcomes including overall survival (OS), event-free survival (EFS), relapse-free survival (RFS) and adverse events (AEs). Results: Of 233 references that met prespecified criteria, 26 studies were included. Adding targeted therapies (venetoclax/ivosidenib) to hypomethylating agents (HMAs) yielded better OS hazard ratios (HRs) (0.44–0.66) and EFS HRs (0.33–0.63) compared with other agents. AEs were more frequent with combination therapies than control arms, except with ivosidenib plus azacitidine. Conclusion: Targeted therapy combined with a HMA shows the most promising results in this difficult-to-treat population.
