结局指标
主要结局
Number of Participants with Adverse Events (AEs) as a Measure of Safety and Tolerability
时间窗: Up to 4 years and 9 months
An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.
Number of Participants with AEs by Severity
时间窗: Up to 4 years and 9 months
Severity will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0. Severity scale ranges from Grade 1 (Mild) to Grade 5 (Death). Grade 1= Mild, Grade 2= Moderate, Grade 3= Severe, Grade 4= Life-threatening and Grade 5= Death related to adverse event.
Percentage of Participants with Dose-Limiting Toxicity (DLT)
时间窗: Up to 28 days Cycle 1
Percentage of participants with DLT will be assessed accordingly to national cancer institute common terminology criteria for adverse events (NCI CTCAE) version 5.
Rate of Complete Remission or Complete Remission with Partial Hematologic Recovery (CR/CRh)
时间窗: Up to 4 years and 9 months
Rate of CR/CRh is defined as the percentage of participants achieving a CR or CRh at any time post-treatment.

- Time To Response (TTR)(Up to 4 years and 9 months)
- Duration of Complete Response (CR)/Complete Remission With Partial Hematologic Recovery (CRh)(Up to 4 years and 9 months)
- Time To CR/CRh(Up to 4 years and 9 months)
- Event-free survival (EFS)(Up to 4 years and 9 months)
- Overall survival (OS)(Up to 4 years and 9 months)
- Measurable Residual Disease (MRD) Negativity Among Participants Achieving CR/CRh/CRi(Up to 4 years and 9 months)
