Vadastuximab（Cat No.:I042249）is an investigational monoclonal antibody designed to target and bind to CD33, a protein expressed on the surface of certain leukemia cells, particularly in acute myeloid leukemia (AML). By targeting CD33, Vadastuximab delivers cytotoxic agents directly to the cancer cells, reducing the potential for damage to healthy tissues. The antibody is part of an antibody-drug conjugate (ADC) approach, where it is linked to a potent chemotherapy drug. Clinical trials are evaluating Vadastuximab’s safety, efficacy, and potential to improve outcomes in patients with CD33-positive AML and other hematological cancers.
