ADA and AACE/ACE Guidelines:Treatment Goals for A1C, FPG, and PPG aThe goal for an individual patient is to achieve an A1C as close to normal (<6%) as possible without significant hypoglycemia. FPG=fasting plasma glucose; PPG=postprandial glucose; ADA=American Diabetes Association; AACE=American Association of Clinical Endocrinologists; ACE=American College of Endocrinology. 1.

Unmet Needs for Type 2 DM Treatment Durable HbA1ccontrol (i.e. help improve Beta-cell function). Addressing islet dysfunction (i.e., addressing both insulin and glucagon secretion. Addressing both fasting and postprandial sugars Minimum risk of treatment-limiting adverse events: -Minimum risk of hypoglycemia -Minimum risk of weight gain -No increased risk of edema -No increased risk of heart failure
