Outcome Measures
Primary Outcome Measures
- Number of Participants with Dose Limiting Toxicity (DLT) [up to 28 days]
Dose limiting toxicity
- objective response rate（ORR） [up to approximately 3 years]
FOR lymphoma ，Objective Response Rate is defined as the percentage of patients with a complete response (CR) or partial response (PR). For AML, the proportion of participants who achieve a best response of CR, CRi, MLFS, or partial response (PR). For MDS, the proportion of participants who achieve a best response of CR, marrow CR, or PR.
Secondary Outcome Measures
- Cmax [up to approximately 3 years]
Cmax is the maximum observed concentration.
- Tmax [up to approximately 3 years]
Time to maximum concentration attained
- Incidence of antidrug antibodies (ADA) [up to approximately 3 years]
Percentage of patients producing detectable ADA
- Duration of remission (DOR) [up to approximately 3 years]
To preliminarily evaluate DoR in patients with hematological malignancies
