Spanning 176 weeks of treatment, the Phase III trial evaluated the efficacy and safety of tirzepatide in adults without type 2 diabetes (T2D) who were either obese or overweight with complications such as cardiovascular disease, dyslipidaemia, hypertension, obstructive or sleep apnoea (OSA).

Eli Lilly said on Wednesday its weight-loss drug helped nearly 99% of patients remain diabetes-free after three years of weekly injections. The results suggest that tirzepatide - the active ingredient in Lilly's diabetes drug Mounjaro and weight-loss treatment Zepbound - could prevent one new case of diabetes for every nine patients treated.
