Asher Bio

Website

At Asher Biotherapeutics, we are pioneering a new approach with our cis‑targeted immunotherapies. Our immunotherapies selectively activate only the immune cell types that drive the desired therapeutic response. With this innovation, we address an inherent shortcoming of conventional immunotherapies, which indiscriminately act on multiple cell types

Overview

Asher Bio is a biotechnology company developing precisely targeted immunotherapies for cancer and other diseases. Our cis-targeting platform aims to enable selective activation of specific immune cell types, addressing the inherent limitations of otherwise pleiotropic immunotherapies that act on multiple cell types. Our approach has the potential to precisely direct different immune mediators against a range of target immune cell-types and create best-in-class immunotherapies in cancer, autoimmune and infectious diseases.

Asher Bio is backed by Third Rock Ventures and is located in South San Francisco.
