Trial Summary

What is the purpose of this trial?

The purpose of the trial is to assess the efficacy and safety of tirzepatide to dulaglutide in participants with type 2 diabetes and increased cardiovascular risk.

Do I need to stop my current medications to join the trial?

The trial information does not specify if you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the drug Tirzepatide for type 2 diabetes?

Tirzepatide has been shown in clinical trials to significantly lower blood sugar levels and reduce body weight in people with type 2 diabetes, with results better than some other diabetes medications. It also appears to be safe for the heart, with no increased risk of major cardiovascular events. ^{1 2 3 4 5}

Is tirzepatide safe for humans?

Tirzepatide has been shown to be generally safe in humans, with common side effects including mild to moderate nausea, vomiting, diarrhea, and constipation, especially at higher doses. It has a safety profile similar to other drugs in its class, with no increased risk of serious cardiovascular events. ^{3 4 5 6 7}

How is the drug tirzepatide different from other treatments for type 2 diabetes?

Tirzepatide is unique because it is the first drug that acts on both GIP and GLP-1 receptors, which helps control blood sugar and reduce body weight more effectively than other treatments. It has shown unprecedented results in lowering blood sugar and weight, making it a novel option for managing type 2 diabetes. ^{2 4 5 8 9}

Findings from Research

Tirzepatide, a medication for type 2 diabetes, shows a dose-dependent increase in gastrointestinal adverse events (AEs), with nausea and diarrhea being the most common, affecting up to 49% of participants at the highest dose (15 mg).

Despite the gastrointestinal side effects, serious adverse events like severe hypoglycemia and acute pancreatitis are rare (≤ 1%), indicating that tirzepatide is generally safe for use in patients with type 2 diabetes.

Adverse Events Related to Tirzepatide. Mishra, R., Raj, R., Elshimy, G., et al.[2023]

Tirzepatide (Mounjaro™) is a new treatment for type 2 diabetes that acts on both GIP and GLP-1 receptors, showing strong results in lowering blood glucose and promoting weight loss based on evidence from five SURPASS clinical trials.

The safety profile of tirzepatide is similar to that of existing GLP-1 receptor agonists, making it a promising option for early intervention in managing type 2 diabetes.

Tirzepatide, approved in 2022, is a novel treatment for type 2 diabetes that acts on both GLP-1 and GIP pathways, showing significant efficacy in lowering blood sugar levels and promoting weight loss in various patient groups.

Clinical trials, including the SURPASS and SURMOUNT studies, indicate that tirzepatide has a safety profile similar to traditional GLP-1 receptor agonists, with common gastrointestinal side effects, making it a promising option for patients needing better glycemic and weight management.

Tirzepatide: Clinical review of the "twincretin" injectable. Krauss, Z., Hintz, A., Fisk, R.[2023]

Tirzepatide demonstrated a dose-dependent ability to lower HbA1c levels in adults with type 2 diabetes, with reductions ranging from -17.71 to -22.35 mmol/mol compared to placebo, and was also more effective in reducing body weight than other treatments.

While tirzepatide did not increase the risk of hypoglycaemia compared to placebo and showed lower rates than basal insulin, it was associated with a higher incidence of gastrointestinal side effects, particularly nausea and vomiting, especially at the 15 mg dose.

Management of type 2 diabetes with the dual GIP/GLP-1 receptor agonist tirzepatide: a systematic review and meta-analysis. Karagiannis, T., Avgerinos, I., Liakos, A., et al.[2023]

Tirzepatide, the first dual GIP/GLP-1 receptor co-agonist approved for type 2 diabetes, significantly reduces HbA1c levels (by 1.24 to 2.58%) and body weight (by 5.4-11.7 kg) in clinical trials involving type 2 diabetic patients, outperforming the selective GLP-1 RA semaglutide.

The safety profile of tirzepatide is similar to that of other GLP-1 receptor agonists, with common side effects including nausea and diarrhea, and it shows potential cardiovascular safety, as no significant increase in major adverse cardiovascular events was observed during the trials.

In a phase 3 trial involving 636 Japanese adults with type 2 diabetes, tirzepatide demonstrated superior efficacy in lowering HbA1c levels compared to dulaglutide, with reductions of -2.4% to -2.8% for tirzepatide versus -1.3% for dulaglutide after 52 weeks.

Tirzepatide also led to significant weight loss, with reductions ranging from -5.8 kg to -10.7 kg depending on the dose, while dulaglutide resulted in only a -0.5 kg reduction, indicating its potential as an effective treatment for both glycemic control and weight management.

Tirzepatide, a novel GLP-1 receptor agonist, has been shown to significantly reduce A1C levels and body weight in patients with type 2 diabetes compared to placebo and other active treatments.

The safety profile of tirzepatide is similar to other GLP-1 receptor agonists, with the most common side effects being mild to moderate gastrointestinal issues, and it does not increase the risk of hypoglycemia, making it a promising treatment option.

Efficacy and Safety of Tirzepatide in Adults With Type 2 Diabetes: A Perspective for Primary Care Providers. Kushner, P., Anderson, JE., Simon, J., et al.[2023]

Tirzepatide, a dual GIP and GLP-1 receptor agonist, has a safety profile similar to other GLP-1 receptor agonists, but higher doses (10mg and above) are associated with increased risks of hypoglycemia and treatment discontinuation.

In clinical trials involving 9818 patients, higher doses of tirzepatide led to more frequent gastrointestinal side effects like nausea, vomiting, and diarrhea, indicating that these adverse events are dose-dependent.

A systematic review of the safety of tirzepatide-a new dual GLP1 and GIP agonist - is its safety profile acceptable? Meng, Z., Yang, M., Wen, H., et al.[2023]

Tirzepatide, a new medication approved by the FDA, acts as an agonist for both GLP-1 and GIP receptors, which helps improve blood sugar control in patients with type II diabetes when combined with diet and exercise.

This drug represents a significant advancement in diabetes management, offering a new approach to treatment by targeting multiple pathways involved in glucose regulation.
