Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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. 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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.
