Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| Relapse-Free Survival (RFS) | 1 year | It is measured from the date of entry into this trial to the date of hematologic relapse or death from any cause. |
| Adverse events in hematological system | 1 month | Record of adverse events in hematological system during and after designed venetoclax combined azacitidine regimen induction. |
| 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. |
| 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. |
