What is the purpose of this trial?

This trial explores a new treatment called Duodenal Mucosal Resurfacing (DMR) for individuals with Type 2 Diabetes who do not see enough improvement with their current medications. The trial aims to compare the effectiveness and safety of DMR against a sham procedure (a fake treatment used as a control) to evaluate its impact on blood sugar, liver, and heart health. Individuals with Type 2 Diabetes, who are on stable diabetes medications and have moderately high blood sugar, might be suitable candidates for this trial. Participants will receive either the DMR treatment or the sham treatment and will be monitored for nearly a year to assess outcomes. As an unphased trial, this study provides a unique opportunity to contribute to groundbreaking research that could lead to new treatment options for Type 2 Diabetes.

Do I need to stop my current medications to join the trial?

The trial does not specify if you need to stop your current medications. However, you must be on at least one glucose-lowering agent without changes for at least 12 weeks before screening. Some medications that interfere with glucose metabolism are prohibited.

What prior data suggests that the Revita® system is safe for patients with Type 2 Diabetes?

Research has shown that Duodenal Mucosal Resurfacing (DMR) is generally safe for people with Type 2 diabetes. One study found that DMR helps improve how the body converts food into energy, enhancing insulin use, which is crucial for blood sugar control. Another study demonstrated that these benefits can last up to two years after treatment. These findings suggest that DMR is well-tolerated, with no major safety concerns reported. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Duodenal Mucosal Resurfacing (DMR) is unique because it uses a novel technique called hydrothermal ablation to target the duodenal mucosa, which is a different approach compared to standard treatments like oral medications or insulin for managing type 2 diabetes. Most traditional treatments focus on regulating blood sugar levels through medications that influence insulin production or sensitivity. In contrast, DMR directly modifies the lining of the intestine to potentially improve metabolic control. Researchers are excited about DMR because it offers a non-drug-based intervention that could benefit patients with inadequately controlled type 2 diabetes, providing a new avenue for treatment that might improve outcomes for those not responding well to current therapies.

What evidence suggests that the Duodenal Mucosal Resurfacing (DMR) procedure is effective for Type 2 Diabetes?

Research has shown that Duodenal Mucosal Resurfacing (DMR), one of the treatments studied in this trial, offers promising effects for people with Type 2 Diabetes. Studies have found that DMR can safely help control blood sugar levels and improve insulin use. Patients have experienced long-lasting benefits, with improvements still visible two years after the procedure. These findings suggest that DMR could be a good option for those whose diabetes isn't well managed by medication alone. The treatment seems to help by targeting the duodenum, an important part of the digestive system that also helps regulate blood sugar. Participants in this trial may receive either the active DMR treatment or a sham procedure for comparison. ^{2 3 4 6 7}
