What is Nisotirostide used for?

Nisotirostide, also known as LY3457263, is a novel peptide that acts as a selective agonist for the neuropeptide Y2 (NPY2) receptor. This receptor is involved in various physiological processes, including appetite regulation and energy homeostasis. By activating the NPY2 receptor, nisotirostide is hypothesized to influence metabolic pathways that can lead to weight loss and improved glycemic control, making it a potential therapeutic option for conditions such as type 2 diabetes and obesity.

Nisotirostide (LY3457263), a novel NPY2 receptor agonist for type 2 diabetes and obesity: From discovery to clinical proof of concept.
FindingNisotirostide reduced mean body weight by 0.75 kg versus placebo (ns); when added to dulaglutide, up to 2.58 kg reduction was observed versus dulaglutide alone (p<0.05).

What people are saying

anecdotal · not evidence

Unverified first-hand accounts from public forums. These are not studies: nobody checked what was taken, whether it was what the label said, or what else was going on. They count for nothing in the evidence grade above and are shown because a reader searching Nisotirostide will meet them anyway, and meeting them next to a graded evidence base is better than meeting them alone.

Community collection has not run yet, so this is an empty shelf rather than a quiet one — nothing has been read, and no conclusion about how much Nisotirostide is discussed should be drawn from it.
