Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a 28-week, multi-center, randomized, double-blind, placebo-controlled trial to study a potential synergistic effect of Dapagliflozin plus Exenatide once-weekly in combination with high-dose intensive insulin therapy compared to Placebo in obese insulin-resistant patients with Type 2 Diabetes mellitus (T2DM) and inadequate glycemic control (HbA1c≥8.0% and ≤ 11.0%).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this proof-of-concept study the potential of treatment with Dapagliflozin plus Exenatide added to high-dose intensive insulin therapy compared to Placebo added to high-dose intensive insulin with active insulin up-titration for change in HbA1c from baseline to week 28 shall be explored and generate initial data on the primary outcome. We hypothesize that SGLT-2 inhibition and GLP-1 receptor agonism may be a rational combination therapy that addresses a broad range of pathophysiological defects associated with T2DM in obesity and may reduce HbA1c levels in patients with severe insulin resistance. In a third treatment arm, patients will be treated with Exenatide monotherapy added to high-dose intensive Insulin therapy to study additive effects of Dapagliflozin and Exenatide.
