This drug was created by Raven biotechnologies, which was later acquired by MacroGenics. It was engineered to increase affinity for CD16A polymorphisms and decrease affinity for FcγRIIB (CD32B), an inhibitory receptor.[3]
It binds to the same target (epitope) as trastuzumab,[4] on the HER2 receptor.
It is in phase 3 clinical trials for combination therapy in metastatic breast cancer[5] in collaboration with Merck.[6] Phase II trials are also in progress for gastric cancer and esophageal cancer.[7]
History
In June 2020, it received orphan drug designation from the U.S. Food and Drug Administration (FDA).[8]
