TGRD is developing an orally active squalene synthase inhibitor, TAK-475 (lapaquistat acetate) for the treatment of dyslipidemia. Lapaquistat acetate inhibits the biosynthesis of cholesterol by inhibiting the enzyme squalene synthase, which catalyzes the conversion of farnesyl diphosphate to squalene—a precursor in the final steps of cholesterol production.
