Frequently asked questions about IcoSema

What is IcoSema used for in Type 2 Diabetes?

IcoSema is an investigational combination of insulin icodec and semaglutide, developed for the treatment of Type 2 Diabetes Mellitus. It is designed to control blood sugar levels in adults with Type 2 Diabetes. IcoSema is administered weekly and is currently in Phase 3 clinical development.

How does IcoSema work?

IcoSema combines insulin icodec, a long-acting basal insulin, with semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist. This dual mechanism aims to improve glycemic control by providing both insulin replacement and enhancing glucose-dependent insulin secretion, while also suppressing glucagon release and slowing gastric emptying.

Who is developing IcoSema?

IcoSema is being developed by Novo Nordisk A/S, a global healthcare company traded on the New York Stock Exchange under the ticker symbol NVO. Novo Nordisk is conducting Phase 3 clinical trials to evaluate the efficacy and safety of IcoSema in people with Type 2 Diabetes.

What phase is IcoSema in?

IcoSema is in Phase 3 clinical development. It is not yet approved by regulatory authorities and remains an investigational medicine. Four clinical trials have been completed, including three Phase 3 studies and one Phase 1 study, with a total enrollment of 2,673 participants.

What clinical trials is IcoSema in?

IcoSema has completed four clinical trials. The Phase 3 trials include NCT05013229 (COMBINE 3), comparing IcoSema to insulin glargine plus insulin aspart; NCT05259033 (COMBINE 2), comparing IcoSema to semaglutide; and NCT05352815, comparing IcoSema to insulin icodec. A Phase 1 trial, NCT05435677, studied the pharmacokinetics in Chinese participants.

Is IcoSema the same as insulin icodec or semaglutide?

IcoSema is a fixed combination of insulin icodec and semaglutide, but it is not the same as either component alone. Insulin icodec is a once-weekly basal insulin, and semaglutide is a once-weekly GLP-1 receptor agonist. IcoSema combines both into a single weekly injection for Type 2 Diabetes.
