SGN-CD33A

About SGN-CD33A

SGN-CD33A is an antibody-drug conjugate (ADC) targeting CD33, a protein that is expressed on most acute myeloid leukemia (AML) cells. SGN-CD33A employs our newest proprietary ADC technology. This technology comprises a potent cell-killing agent called a pyrrolobenzodiazepine (PBD) dimer that works by a different mechanism than auristatins. The PBD dimer is stably linked to an antibody with our site-specific engineered cysteines, resulting in uniform drug-loading of two PBD dimers per antibody. We call this engineered antibody an EC-mAb.

Status

SGN-CD33A is in a phase 1 clinical trial designed to assess its safety and anti-leukemia activity in AML.
