Frequently asked questions about Zenagamtide

What is Zenagamtide used for?

Zenagamtide is an investigational small molecule being developed for the treatment of obesity and overweight. It is currently in Phase 3 clinical trials, which are designed to evaluate its effectiveness in helping people with excess body weight lose weight.

Who is developing Zenagamtide?

Zenagamtide is being developed by Novo Nordisk A/S, a pharmaceutical company listed on the stock exchange under the ticker symbol NVO. The company is conducting Phase 3 clinical trials to investigate the drug's efficacy in treating obesity and overweight.

What phase is Zenagamtide in?

Zenagamtide is currently in Phase 3 clinical development. It is an investigational drug, meaning it has not yet been approved by regulatory authorities. The ongoing Phase 3 trials are designed to assess its safety and efficacy in treating obesity and overweight.

What clinical trials is Zenagamtide in?

Zenagamtide is being studied in three Phase 3 clinical trials: NCT07668401 (AMAZE 13) in Asia, NCT07668414 comparing it to semaglutide in the United States, and NCT07720271 (AMAZE 9) in the United States. These trials are not yet recruiting and have a combined enrollment of approximately 1,600 participants.

Is Zenagamtide the same as semaglutide?

Zenagamtide is not the same as semaglutide. It is a distinct investigational drug being developed by Novo Nordisk. One of its Phase 3 clinical trials (NCT07668414) is specifically designed to compare Zenagamtide against semaglutide to evaluate how well it helps people with excess body weight lose weight.
