We’re learning more about the super-effective “triple-G” weight loss drug retatrutide.

We → learn → drug
The drug, the first of its kind to target three metabolic receptors (GLP-1, GIP, and glucagon), is nearing the end of clinical trials and is expected to be submitted to the FDA for approval early next year.
asserted

New data on its effectiveness is likely to only throw fuel on the fire.

Earlier this year, Eli Lilly reported the results of its Phase 3 “Triumph-4” trial, finding that patients lost an average of 28.7% of their body weight.
asserted
patients → report → weight
In fact, there were higher dropout rates than in earlier trials — with at least some participants stopping because they lost too much weight.
asserted
they → be → weight
They’ve now shared detailed data from a different Phase 3 trial, showing that even on the lowest administered dose, participants saw dramatic results.

Those who got a 4-mg injection once a week — the smallest they offered — lost an average of 29.8 pounds, or 12.7% of their body weight.

they → get → weight
In contrast to GLP-1s like Ozempic, which only target GLP-1 receptors, or dual agonists like Mounjaro or Zepbound, which target GLP-1 and GIP or glucagon, retatrutide targets all three: GLP-1, GIP and glucagon.
asserted
retatrutide → target → three
Lilly released data on three doses of retatrutide: 4 mg, 9 mg, and 12 mg.
asserted
Lilly → release → retatrutide
After being on the drug for 80 weeks (a year and 8 months), participants on the lowest dose lost an average of 29.8 pounds (12.7% of their weight), the medium dose lost 45.4 pounds (19.1%), and the highest dose lost 49.6 pounds (20.8%), respectively.

dose → lose → pounds
What’s more, the drug is also showing great success in lowering participants A1C, or blood sugar — a marker of diabetes.

drug → ’ → diabetes
“The vast majority of people with type 2 diabetes are also living with obesity, and treating the two together has always been a challenge,” said Dr. Juan P. Frías, who led the research.

who → live → research
“Retatrutide reduced both weight and blood sugar substantially, with more than half of participants no longer qualifying as having obesity and up to 40% reaching an A1C in the normal range.”
asserted
% → reduce → range
On the lowest dose, A1C was lowered by an average of 1.4% and with each increase in dose, A1C was lowered .1% on average.
asserted
A1C → lower → dose
The drug also helped with heart health.
asserted
drug → help → health
The highest dose significantly lowered triglycerides, cholesterol, blood pressure (all associated with lower risk for heart disease and stroke), waist circumference (a predictor of heart disease risk), and high-sensitivity C-reactive protein (a marker of future heart risk).
asserted
all → lower → risk
The biggest side effects Lilly noted are typical of GLP-1 drugs: gastrointestinal reactions like diarrhea (seen in 27.4% to 33.6% of participants), nausea, constipation, decreased appetite and vomiting, in order from most to least common.
asserted
Lilly → note → common
In general, the side effects became more common at higher doses.
asserted
effects → become → doses
Researchers also observed dyesthesia, a neurological condition that affects your sense of touch.
asserted
that → observe → touch
It can feel painful or just strange — like burning, cold, pins-and-needles, itching, or wet.
asserted
It → feel → burning
This happened in 4.5 to 7.3% of participants, with an increased incidence as dosing went up.
asserted
dosing → happen → incidence
Some participants also got urinary tract infections (3.8 to 8%) with increased incidence as dosing went up.
asserted
dosing → get → incidence
“These events were generally mild to moderate, and the majority resolved during treatment,” researchers said.
