OSI-7904L is a liposome encapsulated thymidylate synthase inhibitor, which is indicated for use in advanced gastric and/or gastroesophageal adenocarcinoma (A-G/GEJA). Current treatments also inhibit thymidylate synthase but the innovative lipid coating of OSI-7904L allows for more enduring results with administration of the TS inhibitor.
