What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a weight-loss medication called tirzepatide in teenagers who are overweight or obese and have other health problems related to their weight. The study will last about two years and involve multiple visits. Tirzepatide is effective in treating obesity in patients with and without diabetes.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but if you are taking any medications or supplements for weight loss, you must stop them at least 90 days before joining the study.

Is tirzepatide safe for humans?

Tirzepatide has been tested in people with type 2 diabetes and is generally considered safe, with common side effects like nausea, vomiting, diarrhea, and constipation, especially at higher doses. It has also shown no increased risk of serious heart-related events compared to other treatments. ^{1 2 3 4 5}

How is the drug Tirzepatide unique for treating obesity?

Tirzepatide is unique because it combines two actions in one drug, targeting both the GLP-1 and GIP receptors, which helps with significant weight loss and improves other health markers like blood pressure and insulin sensitivity. This dual action makes it more effective than other treatments that only target one receptor. ^{1 6 7 8 9}

What data supports the effectiveness of the drug Tirzepatide for obesity?

Research shows that Tirzepatide, a drug that works on specific hormones in the body, helps people with obesity and type 2 diabetes lose weight effectively. Studies found that it leads to more weight loss compared to other similar treatments and also improves other health factors like blood pressure and insulin sensitivity. ^{6 9 10 11 12}

Published Research Related to This Trial

Tirzepatide significantly reduces body weight in patients with type 2 diabetes and obesity, with an average weight loss of -9.81 kg compared to placebo, based on a meta-analysis of 10 studies involving 9,873 patients.

While tirzepatide is effective for weight loss, it has a higher incidence of gastrointestinal side effects compared to placebo, although serious adverse events and hypoglycemia are less common, indicating a need for monitoring these reactions during treatment.

Weight loss efficiency and safety of tirzepatide: A Systematic review. Lin, F., Yu, B., Ling, B., et al.[2023]

In a 72-week phase 3 trial involving 938 adults with obesity and type 2 diabetes, tirzepatide (10 mg and 15 mg) led to significant weight loss, with reductions of -12.8% and -14.7% respectively, compared to only -3.2% with placebo.

The safety profile of tirzepatide was generally favorable, with most adverse events being mild to moderate gastrointestinal issues, and serious adverse events were rare, indicating it is a safe option for weight management in this population.

Efficacy and safety of tirzepatide for treatment of overweight or obesity. A systematic review and meta-analysis. Tan, B., Pan, XH., Chew, HSJ., et al.[2023]

Tirzepatide, a once-weekly medication for type 2 diabetes, not only improves blood sugar control but also leads to significant weight loss and positive changes in cardiovascular health, such as reduced blood pressure and improved insulin sensitivity.

The weight loss and metabolic benefits of tirzepatide are linked to its dual action as a GIP and GLP-1 receptor agonist, suggesting that these mechanisms play a crucial role in its effectiveness for managing type 2 diabetes.
