About ARR-217

ARR-217 (also known as MRG007) is a potentially best-in-class cadherin-17 (CDH17)-targeted antibody-drug conjugate (ADC), utilizing a glycan-linked, exatecan-based payload. CDH17 is a membranous cell adhesion molecule frequently overexpressed in colorectal cancer and several other gastrointestinal cancers, with limited expression in normal intestinal tissue and pancreatic duct, making it an attractive target for ADC therapy. ArriVent obtained exclusive rights to develop and commercialize ARR-217 worldwide outside of Greater China under a collaboration agreement with Lepu Biopharma Co., Ltd. ARR-217 is the lead clinical candidate from ArriVent's growing ADC portfolio.
