Galectin-9 serves as a key regulator of the immune response to cancer and may work in concert with PD-1 which alone can be targeted to improve the immune systems response to cancer. Galectin-9 is highly expressed across pancreatic cancer and cholangiocarcinoma, two types of cancer that respond poorly to chemotherapy and immunotherapy. A multicenter phase 1/2 study (NCT04666688) is evaluating the safety, and antitumor activity of LYT-200 both as a single agent, and in combination with either chemotherapy or anti–PD-1 therapy in patients with cholangiocarcinoma and pancreatic cancer.
