Study summary

To assess the TANTALUS therapy in type 2 diabetic patients who can not tolerate GLP-1 agonist due to unacceptable side effects; and to assess the TANTALUS therapy in type 2 diabetic patients who do not sufficiently benefit from GLP-1 receptor agonist therapy

Read the detailed description

The present protocol will address whether the effects of the TANTALUS treatment are complimentary to GLP-1 treatment which is only partially effective or whether it can replace GLP-1 treatment in individuals who cannot tolerate GLP-1 agonists because of unacceptable side effects.

This investigation will be a 3 arm multicenter study which will enroll in a Run-In Period up to 400 with type 2 diabetes mellitus. This Run-In Period will facilitate screening the patients with the aim to have a maximum of 30 patients in each arm complete the Evaluation Period of 6 months. The study aims at evaluating the TANTALUS therapy compared to GLP-1 receptor agonist therapy by evaluating improvement in glycemic control and weight after 6 months of treatment in each of the 3 study groups, which are:

  • Group A: subjects on GLP-1 receptor agonist therapy only
  • Group B: subjects on GLP-1 receptor agonist therapy and TANTALUS therapy
  • Group C: subjects on TANTALUS therapy only

    Change in HbA1c and weight will be assessed at baseline and 24 weeks of treatment for Group A and C. Additionally, each group will be analyzed for the weight of decrease extent, the percentage of patients achieving the endpoint, and the percentage of patients that reach an HbA1c less than 7.0%.

    Time frame: 6 month

Secondary outcomes

  1. Glycemic and metabolic parameters

    * Glycemic Parameters (FBG, PPG) * Glycemic Dynamics (Glucose, Insulin, C-Peptide, and Glucagon Profiles) via MTT * Metabolic Parameters (WC, BP, Lipids, Gastric Emptying) * Gastric Hormones (GLP-1, GIP, Ghrelin, PYY, Pancreatic Polypeptide) via MTT
