Maridebart cafraglutide vs. semaglutide for type 2 diabetes on metformin

Official title: A Phase 3, Randomized, Open-Label Trial Comparing the Efficacy and Safety of Maridebart Cafraglutide Once Monthly Versus Semaglutide Once Weekly as Add-on Therapy to Metformin With or Without a Sodium-glucose Cotransporter-2 Inhibitor in Participants With Type 2 Diabetes

Run by Amgen · NCT07866066 · Data updated 2026-11-12

This trial tests whether maridebart cafraglutlide is as good as semaglutide at improving blood sugar in adults with type 2 diabetes who take metformin (with or without an SGLT-2 inhibitor).

Is this trial a fit for you?

Likely a good fit

Adults with type 2 diabetes on metformin (± SGLT-2 inhibitor), with HbA1c 7.5–10.5% and BMI ≥25 kg/m^2.

Probably not a fit

Individuals with type 1 diabetes, certain retinal diseases, or a history of diabetic ketoacidosis may not benefit from this trial.

What this trial studies

This is a Phase 3, non-inferiority study comparing maridebart cafraglutlutide to semaglutide in adults with type 2 diabetes who are on metformin, with or without an SGLT-2 inhibitor. Participants must have an HbA1c between 7.5% and 10.5% and a BMI of at least 25 kg/m^2. The trial is conducted at multiple sites in the United States and is sponsored by Amgen. Primary outcomes focus on glycemic control; secondary considerations include safety and tolerability. Enrollment targets adults with prior metformin therapy and stable background therapy, excluding those with certain retinopathy conditions or a history of type 1 diabetes.

Why it matters

Potential benefit: If successful, participants may experience better or comparable blood sugar control with a potentially favorable safety profile compared with semaglutide.

How similar studies have gone: Previous similar GLP-1 receptor agonist comparisons have shown non-inferiority signals in glycemic outcomes, supporting the need for this direct comparison.

Inclusion Criteria:

* HbA1c of ≥ 7.5% (58.0 millimoles per mole (mmol/mol)) and ≤ 10.5% (91.0 mmol/mol) at screening.
* Treatment of Type 2 diabetes (T2D) with metformin (≥ 1500 milligrams per day (mg/day), or maximum tolerated dose as per investigator judgment) with or without an sodium-glucose cotransporter-2 (SGLT-2) inhibitor on a stable total daily dose for at least 90 days prior to randomization.
* Body mass index (BMI) ≥ 25 kilograms per meter squared (kg/m\^2) at screening.

Exclusion Criteria:

* Type 1 diabetes mellitus (T1DM), history of ketoacidosis or hyperosmolar state/coma, or any other type of diabetes mellitus except T2D or past history of gestational diabetes.
* Participants who are currently receiving or planning to receive treatment for diabetic retinopathy and/or macular edema.
* Participants who have a diagnosis of proliferative diabetic retinopathy, diabetic maculopathy, or severe non-proliferative diabetic retinopathy.
* One or more episode of severe hypoglycemia (Level 3 hypoglycemia) within 180 days before screening, as defined by the occurrence of neuroglycopenic symptoms requiring the assistance of another person for recovery.
* History of hypoglycemia unawareness or poor recognition of hypoglycemic symptoms.
* Self-reported change in body weight \> 5% within 90 days before screening. Participants must also agree to not initiate an intensive diet or exercise program during the trial with the intent of reducing body weight, other than the lifestyle and/or dietary measures for diabetes treatment.
* Previous or planned (during the trial) surgical, endoscopic, or device-based treatment for obesity. The following are allowed:

  * liposuction and/or abdominoplasty that was performed \> 1 year before screening.
  * laparoscopic adjustable gastric banding, intragastric balloon, and/or duodenal-jejunal bypass liner or gastric sleeve if removed \> 1 year before screening.
