Brief summary
300 patients will be randomly distributed into the control group (n=150) and the experimental group(n=150). Patients will receive two cycles of induction chemotherapy. The control group receives standard 3+7 induction regimen containing cytarabine (100mg/m2 d1-7) and daunorubicin (60mg/m2 d1-3). The experimental group receives venetoclax combined with intensive chemotherapy (3+7 induction regimen same as the control group). For each group, patients who fail to achieve CR/CRi after two courses of induction therapy may receive alternative therapy decided by their physicians. After CR/CRi achieved, subjects proceed allo-transplantation or consolidation therapy according to their ELN risks: subjects in favorable risk group should continue with chemotherapy; subjects in poor risk group should go through transplantation; for subjects in intermediate risk group, those with suitable donors can receive transplantation while others can continue with consolidation therapy. Subjects receive 3 courses of intermediate-dose cytarabine (1.5g/m2 q12h d1, 3, 5) for age\>55 years or high dose cytarabine (3g/m2 q12h d1, 3, 5) for age≤ 55 years as consolidation therapy with venetoclax in experimental group and without venetoclax in control group. After consolidation, patients will be observed.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Event-free survival | up to 12 months | The time from randomization to treatment failure, death from any cause or relapse after achieving CR or CRi, whichever occurs first. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| CR rate | up to 2 months | The proportion of patients achieving CR after two cycles of induction chemotherapy. |
| Rates of remission (CR/CRi) without measurable residual disease (CRMRD-) | up to 2 months | The proportion of AML patients achieving CR/CRi with negativity for a genetic marker by real-time quantitative polymerase chain reaction and/or with negativity by multi-color flow cytometry. |
| Overall survival Overall survival | up to 36 months | The time from randomization to death resulting from any cause |
| Cumulative incidence of relapse | up to 36 months | Calculated from tdate of first CR to the date of relapse, considering nonrelapse mortality (NRM) as a competing event |
| Frequency and severity of AEs | up to 8 months | Adverse clinical events in the course of drug treatment according to CTCAE v5.0. |
| Relapse free survival | up to 36 months | From the date of complete remission(CR) until the date of documented relapse or death due to any cause or the last follow-up day. |
