What is Palupiprant?

Palupiprant is an orally bioavailable antagonist of the prostaglandin E2 receptor type 4 (EP4). It targets and blocks immunosuppressive tumor-associated myeloid cells in the tumor microenvironment, which is intended to reduce their immunosuppressive activity and tumor cell proliferation. It is studied in rectal cancer and locally advanced solid tumors.
