What benefits of Mounjaro have been shown in studies?

Mounjaro was effective at helping people lose weight in a study involving more than 2,500 adults who had obesity (BMI over 30kg/m2) or who were overweight (BMI between 27 and 30 kg/m2) and had at least one weight-related health problem.

In this study, people who used Mounjaro in combination with diet and physical activity for 72 weeks reduced their weight by at least 15% on average, depending on the dose they were given.

This compares with 3% in people who were given a placebo. Over 85% of people taking Mounjaro were able to reduce their weight by at least 5%, compared with 35% of people given placebo.
