Monocentric experience of venetoclax-based regimen in paediatric refractory and relapsed AML/MDS

BCL-2 inhibitor venetoclax demonstrates promising efficacy in paediatric relapsed/refractory acute myeloid leukaemia (r/r AML). This retrospective analysis evaluated 12 patients treated with venetoclax-based regimens under compassionate use for r/r myeloid malignancies. The overall response rate (ORR) was 41.6%, with complete response (CR) achieved in 33% of patients. Three patients successfully underwent allogeneic haematopoietic scell transplantation (HSCT) after venetoclax bridging therapy. Venetoclax demonstrated a favourable safety profile with manageable side effects. These findings suggest venetoclax's potential as a valuable therapeutic option for paediatric r/r AML, particularly for heavily pretreated patients. Further investigation in larger multicentre trials is warranted to refine treatment strategy.
