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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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. There will be 2 parts of this study. The phase Ib is about monotherapy of 6MW3211 and Phase II is designed to evaluate the safety and efficacy of 6MW3211 combined with AZA or AZA plus VEN in patients with relapse/refractory and newly diagnosed AML and MDS.
