Oct 28 (Reuters) – Eli Lilly’s experimental next-generation drug retatrutide outperformed a lower-dose version of Novo Nordisk’s Ozempic on blood sugar control and ​showed more than double weight loss in ‌a study of adults with type 2 diabetes.

The head-to-head trial compared 9 mg and 12 mg doses of Lilly’s retatrutide with a 2 mg dose of Novo’s diabetes drug Ozempic, ‌Lilly ​said on Wednesday.

Here are some details:

• ⁠In the late-stage ⁠trial, both doses of retatrutide lowered A1C, a measure of blood sugar over time, by an average of 2.2% compared with Ozempic’s 1.8% at ​80 weeks

• Those taking retatrutide lost an average of 44.3 pounds on the 9mg dose and ⁠47.4 pounds on 12 mg ⁠compared with 20.9 pounds with Ozempic

• ​Lilly said the trial used Ozempic 2 mg as ​a comparator as it is the highest approved ‌dose available

• Retatrutide also delivered greater improvements than Ozempic across certain cardiovascular risk factors

• “Based on these results and those from across our Phase 3 program, ⁠we believe retatrutide, if approved, could shift the treatment paradigm for people living with type 2 diabetes, obesity and ⁠related cardiometabolic ‌conditions,” said Kenneth Custer, president of ⁠Lilly Cardiometabolic Health

• The once weekly drug, ​retatrutide, ‌activates three hormone receptors – GLP-1, GIP ​and glucagon – ⁠earning it the nickname “triple-G”

• Triple-G weight-loss drugs are expected to produce greater weight loss than earlier generations by combining appetite suppression, blood sugar control and increased calorie burning
