Dapagliflozin

Dapagliflozin (DAPA) is a selective inhibitor of the renal sodium-glucose co-transporter 2 (SGLT2) that lowers plasma glucose levels in patients with T2DM by inhibiting renal glucose reabsorption.

• Impaired insulin secretion and insulin resistance are the main defects in type 2 diabetes mellitus (T2DM).1

• Normalization of plasma glucose by phlorizin (SGLT2 inhibition) in diabetic rats led to correction of insulin secretion.2

• DAPA has also been shown to preserve β-cell function and pancreatic islet morphology in animal models.3

• The aim of this presentation is to present select efficacy and safety data from two Phase 3, randomized, double-blind, placebo-controlled, multicenter trials. The data suggest that DAPA produces improvement in glycemic parameters and improves beta-cell function without causing hypoglycemia.

Summary of Hypoglycemic Events

*Patient experienced a minor and other episode during the trial.

Major: symptomatic with plasma glucose <54 mg/dL and requires assistance due to severe impairment in consciousness or behaviorMinor: symptomatic with plasma glucose <63 mg/dL regardless of need for external assistanceOther: episodes suggestive of hypoglycemia but not meeting above criteria 15

Page 16: Afshin Salsali MD, Arnaud Bastien MD, Traci Mansfield PhD,

Conclusions

• DAPA as monotherapy or add-on to metformin improved glycemic control in patients with T2DM.

• Improvements in glycemic control were accompanied by improvements in β-cell function as assessed by HOMA–2%β and HOMA–2 IS. • Events of hypoglycemia were infrequent and occurred in similar proportions in the DAPA and placebo groups.

–There were no episodes of major hypoglycemia reported.
