Clever-1 - A Unique Immune Checkpoint

Clever-1 is an immunosuppressive receptor found on macrophages that leads to tumor growth and metastases (i.e., it helps cancer to evade the immune system) and, for Faron, is a novel immune checkpoint target for drug development. 

Macrophages are a type of myeloid cell that play an essential role in the immune system. But they are also one of the most abundant immune cells to be recruited into the tumor microenvironment: the ecosystem of cells that surrounds a tumor, employing multiple mechanisms to evade the immune system and directly promote tumor growth inside the body.

By targeting the Clever-1 receptor on macrophages, Faron's lead asset, bexmarilimab, alters the tumor microenvironment, reprogramming macrophages from an immunosuppressive (M2) state to an immunostimulatory (M1) one, upregulating interferon production and priming the immune system to attack tumors and sensitizing cancer cells to standard of care.
