Retatrutide is a triple agonist weight-loss drug being developed for obesity and other weight-related conditions. It is a once-weekly injection designed to target three receptors involved in appetite and metabolism: GIP, GLP-1, and glucagon. Because it activates all three, Retatrutide is often referred to as a “Triple G” weight-loss medication or a triple hormone receptor agonist.
Retatrutide may support weight loss by:
- reducing appetite
- increasing feelings of fullness
- slowing digestion
- increasing energy expenditure
- improving fat breakdown
- reducing fat storage
How Does Retatrutide Work?
Retatrutide is a triple hormone receptor agonist in development for the treatment of obesity. It works by targeting three different hunger- and metabolism-related hormones: GIP, GLP-1, and GCG (glucagon).
Retatrutide delivered major weight loss in TRIUMPH-4 (NCT05869903), with average weight reductions of 26.4% at 9 mg and 28.7% at 12 mg.
That translated to about:
- 64.2 lbs (29.1 kg) lost with Retatrutide 9 mg
- 71.2 lbs (32.3 kg) lost with Retatrutide 12 mg
By comparison, the placebo produced only 2.1% weight loss.
A high proportion of participants taking Retatrutide achieved clinically meaningful weight loss:
- 25% or more weight loss: 47.7% to 58.6%
- 30% or more weight loss: 30.5% to 39.4%*
- 35% or more weight loss: 18.2% to 23.7%*
Up to 73.0% of Retatrutide 9 mg participants achieved at least a 70% reduction in WOMAC pain, compared with 26.2% on placebo.
