Is cagriSema FDA-approved?

Investigational. Not FDA-approved.

Overview

CagriSema pairs two fullness signals in one weekly shot. In the 68-week REDEFINE 1 trial in adults with obesity, average weight loss was 20.4% versus 3.0% on placebo. In REDEFINE 2, in people with obesity and type 2 diabetes, it was 13.7% versus 3.4%. Stomach side effects were common.

How it works

Semaglutide works on GLP-1 receptors; cagrilintide works on amylin receptors. The two pathways add up, so the combo produces more weight loss than either one alone.

How long does cagriSema stay in the body?

Both parts last about a week in the body, so it's taken once weekly.
