Outcome Measures
Primary Outcome Measures
- Overall Response Rate (ORR) [At the end of Cycle 1 (each cycle is 21 days)]
The overall response (complete remission, complete remission with incomplete blood count recovery) rate achieved after one or two courses (21 days) induction therapy by venetoclax combined azacitidine regimen.
- Complete Remission Rate (CRR) [At the end of Cycle 1 (each cycle is 21 days)]
The complete remission rate achieved after one or two courses (21 days) induction therapy by venetoclax combined azacitidine regimen.
Secondary Outcome Measures
- Overall survial (OS) [1 year]
It is measured from the date of entry into this trial to the date of death from any cause; patients not known to have died at last follow-up are censored on the date they were last known to be alive.
- Progression-Free Survival (PFS) [1 year]
It is measured from the date of entry into this trial to the date of progression or death.
- Adverse events in hematological system [1 month]
Record of adverse events in hematological system during and after designed venetoclax combined azacitidine regimen induction.
- Adverse events in other organs or systems [1 month]
Record of adverse events in other organs or systmes during and after designed venetoclax combined azacitidine regimen induction.
