What You Need to Know Before You Apply

What is the purpose of this trial?

A phase 2 study to assess the efficacy of NA-931 alone or in addition to Tirzepatide to assess efficacy and safety in overweight or obese men and women

Will I have to stop taking my current medications?

The trial requires that you stop taking any medication specifically for obesity within 30 days before screening. If you are taking medication for diabetes, you may need to stop if it is not metformin or an SGLT2 inhibitor, as these are allowed for metabolic syndrome.

Is tirzepatide safe for humans?

Tirzepatide has been studied for type 2 diabetes and shows a safety profile similar to other medications in its class, with common side effects like nausea, vomiting, diarrhea, and constipation, especially at higher doses. It has been associated with a reduction in cardiovascular events, and no increased risk of major cardiovascular issues was found in studies. ^{1 2 3 4 5}

How is the drug NA-931 and Tirzepatide unique for treating obesity?

Tirzepatide is unique because it is a dual-action drug that targets both the GIP and GLP-1 receptors, which helps with significant weight loss and improves other metabolic health markers. This dual mechanism is different from other treatments that typically target only one of these pathways. ^{1 4 6 7 8}

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

Research shows that tirzepatide, a drug that helps control blood sugar and reduce appetite, is effective for weight loss in people with obesity and type 2 diabetes. It has been shown to lead to more weight loss compared to other similar treatments and also improves other health factors like blood pressure and fat levels. ^{6 7 8 9 10}

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]

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.

Perspectives on weight control in diabetes - Tirzepatide. Várkonyi, TT., Pósa, A., Pávó, N., et al.[2023]

Tirzepatide is a novel medication that acts on both GIP and GLP-1 receptors, enhancing insulin secretion and reducing glucagon levels, which helps improve glycemic control in adults with type 2 diabetes mellitus (T2DM).

It received its first approval in the USA in May 2022 for T2DM treatment and is currently being studied for additional conditions like obesity, heart failure, and non-alcoholic steatohepatitis, indicating its potential for broader therapeutic applications.

Tirzepatide: First Approval. Syed, YY.[2022]

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.

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.

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, 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, 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.

Tirzepatide, a dual GIP/GLP-1 receptor co-agonist for the treatment of type 2 diabetes with unmatched effectiveness regrading glycaemic control and body weight reduction. Nauck, MA., D'Alessio, DA.[2022]

Tirzepatide, a dual GIP and GLP-1 receptor agonist, showed significant reductions in Hemoglobin A1c levels (up to 3.02%) and weight loss in adults with uncontrolled type 2 diabetes, outperforming both placebo and active comparators like semaglutide.

The safety profile of tirzepatide was comparable to semaglutide regarding gastrointestinal adverse effects, and it did not increase the incidence of major cardiovascular events compared to insulin glargine, indicating it may be a valuable addition to diabetes treatments.

Tirzepatide, a once-weekly GIP/GLP-1 receptor agonist, is being evaluated in a large cardiovascular outcomes trial involving 13,299 participants with type 2 diabetes and established cardiovascular disease to assess its safety and efficacy compared to dulaglutide.

The primary goal of the trial is to determine if tirzepatide is noninferior to dulaglutide in preventing major adverse cardiovascular events (MACE), which will help establish its cardiovascular benefits in this patient population.
