Merck announced that a Phase 3 study (VERTIS SITA2) of ertugliflozin, an investigational oral SGLT2 inhibitor for the treatment of patients with type 2 diabetes, met its primary endpoint. Both 5 mg and 15 mg daily doses of ertugliflozin showed significantly greater reductions in A1C* of 0.69 percent and 0.76 percent, respectively, compared with placebo (p<0.001, for both comparisons), when added to patients on a background of sitagliptin (100 mg/day) and stable metformin (≥1500 mg/day). These study results were presented for the first time during an oral session at the 52nd Annual Meeting of the European Association for the Study of Diabetes (EASD) in Munich, Germany.
