Selvigaltin (GB1211) is the first small-molecule, orally delivered galectin-3 inhibitor to be discovered.^[1] It is developed by Galecto Biotech, which is testing the molecule to see if it reduces decompensated cirrhosis ^[2] and resistance to checkpoint inhibitors (a type of anti-cancer drug).^[3]^[4]
