Study Overview
Brief Summary
This is a phase 2 study designed to evaluate the efficacy of daily (QD) oral RGT001-075 GLP1 receptor agonist relative to placebo after up to 16 weeks of double-blind treatment as determined by mean change from baseline in HbA1c in adult patients with Type 2 Diabetes Mellitus (T2DM) who have inadequate glycemic control with diet and exercise and stable metformin treatment.
