Type 2 Diabetes: Insulin-Free for 24 Months After Novel Endoscopic Procedure

TOPLINE:

VIENNA, AUSTRIA — Participants with type 2 diabetes who were able to stop insulin for up to 12 months after receiving the novel recellularization via electroporation therapy (ReCET) procedure in combination with treatment with semaglutide maintained their response at 24 months.

METHODOLOGY:

• ReCET technology, manufactured by Endogenex, uses a specialized catheter that ablates the duodenal mucosa with electroporation, enhancing sensitivity to endogenous insulin.
• In the first-in-human study, a total of 14 participants (aged 28-75 years; body mass index, 24-40) underwent the ReCET procedure. They then followed a 2-week isocaloric liquid diet, after which they were initiated on semaglutide and gradually titrated up to 1 mg/wk.
• Patients were followed for a total of 24 months.

TAKEAWAY:

• Of the 14 participants, 12 (86%) no longer required insulin at the 6- and 12-month follow-ups.
• At the 24-month follow-up, 11 patients were still insulin-free while maintaining A1c levels below 7.5%. (One patient withdrew consent at 18 months.)
• Semaglutide at the maximum dose was well-tolerated by 93% of participants. One patient experienced nausea that limited titration to the maximum dose. There were no serious adverse events to the ReCET procedure.
• Researchers have started the EMINENT-2 trial that will compare the use of ReCET with a sham procedure. All patients will still receive semaglutide.

IN PRACTICE:

• “These findings are very encouraging, suggesting that ReCET is a safe and feasible procedure that, when combined with semaglutide, can effectively eliminate the need for insulin therapy,” said the study’s lead author.
• It’s a novel way of treating type 2 diabetes using a single endoscopic procedure instead of repeated insulin injections, Busch explained. “But we do need to consider whether repeat treatment will be necessary because I don’t believe this will be forever.”
