Oral GLP-1 Candidate Improves Blood Sugar and Weight in Phase 2b Trial

The SOLSTICE trial found that elecoglipron, an oral small-molecule GLP-1 receptor agonist, lowered glucose and weight in adults with type 2 diabetes, with results presented at ADA and published in The Lancet.

Mass General Brigham reported results from SOLSTICE, a phase 2b randomized, placebo-controlled trial of elecoglipron, an oral small-molecule GLP-1 receptor agonist for adults with type 2 diabetes.

The trial enrolled 406 adults across nine countries and tested different starting doses, dose-escalation approaches and maintenance doses. Results were presented at the American Diabetes Association Scientific Sessions and published simultaneously in The Lancet.

After 26 weeks, elecoglipron lowered glucose more than placebo across tested doses. Up to 89.6% of participants receiving the drug reached an HbA1c level of 7%, compared with 24.9% in the placebo group.

The study also reported weight effects: up to 72.3% of people taking elecoglipron achieved at least 5% body-weight reduction, compared with 20.2% on placebo. Researchers said the safety and tolerability profile was broadly consistent with other GLP-1 therapies at this stage.

Why It Matters

Injectable GLP-1 drugs have reshaped diabetes and obesity care, but route, dosing and access remain practical barriers. A small-molecule oral GLP-1 with strong phase 2b data could broaden the field if later trials confirm efficacy, safety, adherence advantages and manufacturing scale.
