Targeting Sugars that Let Cancers Evade the Immune System

It’s been understood for more than 60 years that cancer cells overproduce sugars on their surface. More recently it’s been discovered that these sugars can help cancer cells evade the immune system. Palleon Pharmaceuticals is developing immunotherapies that work by targeting these cell surface sugars and make them vulnerable to attack. We spoke to David Feltquate, chief medical officer of Palleon, about the potential to harness glycobiology to treat cancer, how the company is working to modulate cell-surface sugars, and its emerging pipeline of glyco-immuno therapies.
