Edrecolomab (MAb17-1A, trade name Panorex) is a mouse-derived monoclonal antibody targeting the cell-surface glycoprotein EpCAM (17-1A), which is expressed on epithelial tissues and on various carcinomas.

Preliminary studies had shown promise of a possible use in patients with stage III colorectal carcinoma (with metastasis to the lymph nodes).[1][2] No effect has been demonstrated for stage II (locally advanced cancer without spread to the lymph nodes) colon cancer.[3]

Edrecolomab was well tolerated in these studies and as such research has now concentrated on whether it can be of any use in other forms of cancer.
