Frequently asked questions about UBT251

What is UBT251?

UBT251 is an investigational small molecule developed by Novo Nordisk A/S for metabolic conditions. It is being studied in type 2 diabetes, obesity, and overweight. It is not approved and remains in clinical development, with Phase 2 trials currently recruiting.

What does UBT251 target?

UBT251 targets the GLP-1, GIP, and GCG receptors, a triple receptor agonist profile. By acting on these three receptors, it is designed to influence metabolic pathways relevant to blood sugar control and body weight. Novo Nordisk is developing it as a small molecule for type 2 diabetes, obesity, and overweight.

Who makes UBT251?

Novo Nordisk A/S develops UBT251. The company trades under the ticker NVO. Novo Nordisk is running the clinical program, which includes Phase 1 and Phase 2 studies in the United States, Canada, Europe, Australia, and South Korea.

What phase is UBT251 in?

UBT251 is in Phase 2 clinical development. It is investigational and has not been approved by the FDA. The Phase 2 program includes a type 2 diabetes study and an overweight or obesity study, both currently recruiting, alongside two Phase 1 drug interaction studies.

What clinical trials is UBT251 in?

UBT251 is being studied in four recruiting trials. NCT07668388 is a Phase 2 type 2 diabetes study enrolling 300 participants, and NCT07395687 is a Phase 2 overweight or obesity study enrolling 333. Phase 1 studies NCT07710768 and NCT07710729 each enroll about 40 participants.

What is UBT251 used for in type 2 diabetes?

UBT251 is being evaluated in type 2 diabetes as an investigational treatment to lower blood sugar. The Phase 2 trial NCT07668388 compares different doses of UBT251 in adults with type 2 diabetes across sites in the United States, Australia, Germany, Hungary, Poland, Romania, Slovakia, South Korea, and Spain.
