Brief Summary

This study is aimed to evaluate the efficacy, safety, immunogenicity and pharmkinetics, pharmacodynamics of 6MW3211 as monotherapy and in combination with AZA or AZA plus VEN in patients with AML/MDS.

Detailed Description

This study is a phase I/II study to evaluate the pharmacokinetics, pharmacodynamics, efficacy and safety of 6MW3211 monotherapy or combined with AZA or AZA plus VEN in patients with AML and MDS.
