The study focuses on children who have experienced a return of acute myeloid leukemia, a type of blood cancer. The treatment being tested adds the oral medication venetoclax to a standard chemotherapy combination that includes the medicines fludarabine (given under the skin), cytarabine (given through a vein), and gemtuzumab ozogamicin (also given through a vein). The purpose of the study is to determine whether the addition of venetoclax can improve overall survival, which means the length of time a child lives after starting treatment.
Participants are randomly assigned to receive either the standard chemotherapy regimen alone or the same regimen plus venetoclax. Treatment cycles are given over several weeks, followed by regular clinic visits to monitor health and any side effects. After the treatment period, children continue to be followed for a longer time to see how long they remain alive and to gather information on their recovery.
