Background: DMR is a minimally invasive, endoscopic procedure designed to treat insulin resistance-related metabolic diseases via hydrothermal rejuvenation of duodenal mucosa leading to improvement in insulin sensitivity. Primary (24 week) results from REVITA-2, the first randomized, sham-controlled, double-blind, prospective, multicenter study, demonstrated that a single DMR procedure safely elicits significant improvements in glycemic and hepatic parameters in sub-optimally controlled T2D. Here we report on durability of glycemic results through 48 weeks posttreatment in REVITA-2 patients at 9 European study centers.
Method: Eligible patients were aged 28-75 years, taking ≥ 1 OAD, had HbA1c levels 7.5%-10.0%, and BMI of 24-40 kg/m2. The modified intent-to-treat (mITT) population included randomized patients in whom a procedure was attempted. Patients lost to follow up were excluded, and data obtained post-rescue medication were set to missing. Significance (0.05 level) was determined using a 2-sided Wilcoxon signed-rank test.
Results: Thirty-one of 39 patients randomized to DMR (mITT) were followed to 48 weeks. Median change from baseline HbA1c was -0.6% at 24 weeks (n = 38, p = 0.003) and -0.7% at 48 weeks (n = 27, p &lt; 0.001). Sixty-eight percent of patients achieved a reduction in HbA1c from baseline at 24 weeks (median HbA1c change: -1.1%) and were defined as responders. Most responders (84%) maintained a durable response through 48 weeks (median HbA1c change: -1.0%) without an increase in antidiabetic medication. Median weight change was -2.4 kg at 24 weeks (n = 38, p &lt; 0.001) and -2.1 kg at 48 weeks (n = 28, p = 0.003).
Conclusion: A single DMR procedure safely elicits durable, clinically significant glycemic improvements through 48 weeks posttreatment in suboptimally controlled T2D; most patients who respond at 24 weeks maintain the beneficial effects at 48 weeks without needing additional medication.
