- Brief Summary
The goal of this clinical trial is to estimate the rate (probability) of complete remission or complete remission with incomplete count recovery (CR/CRi) with negative MRD after induction I and II, event-free survival (EFS), and cumulative incidence (probability) of relapse (CIR), in patients receiving molecular/precision medicine and MRD-driven remission in...
- Detailed Description
Advances in risk stratification and therapy, have improved the event-free survival (EFS) and overall survival (OS) for pediatric acute myeloid leukemia (AML) with current treatment strategies. Investigators previously conducted a multicenter, randomized controlled trial (AML18) to compare the efficacy and safety of low-dose chemotherapy versus standard-dose ...

- Primary Outcome Measures
Name Time Method Rate of CR/CRi with negative MRD Day 26 (HAE group) and Day 32 (MAG+Ven group) for remission induction 1 and 2 are the necessary time points for response evaluation. CR/CRi with negative MRD was defined as less than 5% blasts in bone marrow and MRD \<0.1%.
Event-free survival From date of treatment until the date of the occurrence of the event, whichever comes first, assessed up to 72 months. Patients remaining event-free are censored at the last follow-up time. Events/failures of EFS include any-cause death, relapse, second malignancy, no CR after Indiction II and off-therapy due to abandonment or attending physician's decision.
Induction II and off-therapy due to abandonment or attending physician's decision.Cumulative incidence of relapse From date of treatment until the date of when a failure of CIR occurs, whichever comes first, assessed up to 72 months. Failures of CIR only include relapse and no CR after Induction 2. Other failures including death in resission (before repalse), second malignancy, and off-therapy due to abandonment or attending physician's decision are considered competing risk.
