At a glance

What is it—and why does it matter?

Amycretin is a single molecule that acts as both a GLP-1 receptor agonist and an amylin receptor agonist. The study aimed to test amycretin’s safety, tolerability, pharmacokinetics, and pharmacodynamic effects in adults with overweight or obesity using single and multiple ascending doses. In this network meta-analysis, high-dose subcutaneous amycretin reduced percent body weight versus placebo by -23.95% (P score 1.00). Amycretin plasma concentrations were consistent with dose proportionality across treatment groups.

Simple guide

Amycretin, in plain English

The main points from the published research. Each one links to the source it comes from.

What it is

What the research looks like

Most published findings come from studies in people.

Who or what was studied, across 20 findings:
  • 18 People 90%
  • 1 Animals or lab 5%
  • 1 Other or unclear 5%

Counts show where findings come from, not how strong they are. Animal and lab findings are counted together because study types have not been labelled for this profile yet.

What studies in people found

What animal and lab studies suggest

Not proven in people. Results in animals or cells often do not hold up in humans.

No main results from animal or lab studies are published here yet. 1 related finding is listed with all findings below.

Safety

No safety findings are published in this profile yet. Missing safety data does not mean it is safe.

What we don't know

  • Not yet covered in this profile: administration, contraindications, interactions, regulatory status, safety.

A missing finding does not mean something is safe or effective.

Study types are labelled automatically and can be wrong; each finding links to its source.
