| Clone ID | HPN601 |
| Biological activity | HPN601 shows durable tumor regression in a humanized rodent tumor model and can be safely administered at doses tenfold higher than the minimal efficacious dose, while higher doses produce toxicities including elevated ALT/AST, bilirubin, body weight loss, and histopathological evidence of tissue damage [1]. HPN601 demonstrates a tenfold improved therapeutic window compared to a constitutively active EpCAM-targeting T cell engager and significantly attenuates cytokine production including IFN-γ, IL-2, IL-6, and IL-10 in non-human primates [1]. |

| Background | Epithelial cell adhesion molecule (CD326/EPCAM) is a ~34 kDa protein. May act as a physical homophilic interaction molecule between intestinal epithelial cells (IECs) and intraepithelial lymphocytes (IELs) at the mucosal epithelium for providing immunological barrier as a first line of defense against mucosal infection. Plays a role in embryonic stem cells proliferation and differentiation. Up-regulates the expression of FABP5, MYC and cyclins A and E. |
