SGN-CD33A: a novel CD33-targeting antibody–drug conjugate using a pyrrolobenzodiazepine dimer is active in models of drug-resistant AML

Key Points SGN-CD33A is a novel antibody-drug conjugate, consisting of an engineered anti-CD33 mAb conjugated to a potent DNA cross-linking cytotoxin. SGN-CD33A is highly active in a broad panel of preclinical AML models and, in contrast to GO, is active despite MDR or poor-risk...
