What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores how semaglutide can manage blood sugar and improve heart health in individuals with early-stage Type 1 Diabetes. Participants will receive either semaglutide or a placebo, followed by a meal to observe their body's reaction. The goal is to understand the drug’s effect when used alongside teplizumab in controlling blood sugar and maintaining healthy blood vessels. Individuals with early-stage Type 1 Diabetes and conditions like high fasting blood sugar might be suitable for this trial. As an Early Phase 1 trial, this research seeks to understand how semaglutide works in people, offering participants a chance to be among the first to explore its potential benefits.

Will I have to stop taking my current medications?

Yes, you will need to stop taking certain medications before joining the trial. Specifically, you cannot take any diabetes medications, antioxidant vitamin supplements within 2 weeks before the study, or several other listed medications like systemic glucocorticoids, antipsychotics, and certain blood pressure and cholesterol medications.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that semaglutide, a pill, has been studied for safety in various situations. Although it hasn't been specifically tested in people with early-stage Type 1 Diabetes, some studies suggest it can lower the risk of heart problems in people with diabetes, indicating potential heart safety.

In some cases, semaglutide has been used for Type 1 Diabetes, despite not being officially approved for this use, and it has shown some benefits. However, it is generally not recommended for people with Type 1 Diabetes, so further research is needed to confirm its safety and effectiveness for them.

Ongoing studies are examining common side effects like low blood sugar and stomach issues. Since this trial is in an early phase, it focuses on basic safety and how well people tolerate the treatment. While the results are promising, more information is needed to fully understand semaglutide's safety for early-stage Type 1 Diabetes.¹ ² ³ ⁴ ⁵

Why do researchers think this study treatment might be promising for Type 1 Diabetes?

Unlike the standard care for early type 1 diabetes, which typically involves insulin therapy and lifestyle adjustments, semaglutide offers a novel approach. Semaglutide, marketed as Rybelsus®, is unique because it is an oral medication that mimics a natural hormone called GLP-1, which plays a role in blood sugar regulation. Most diabetes treatments focus on insulin replacement or sensitivity, but semaglutide works differently by enhancing insulin secretion and reducing glucose production. Researchers are excited about semaglutide because it could offer a convenient, once-daily oral option that may help manage blood sugar levels without the need for injections, potentially improving the quality of life for patients.

What evidence suggests that semaglutide might be an effective treatment for early Type 1 Diabetes?

Research shows that semaglutide, a type of medication, can help control blood sugar levels. In studies with people who have Type 2 diabetes, semaglutide improved blood sugar control and benefited heart health. Evidence also suggests it may aid in weight loss and reduce the need for insulin in people with Type 1 diabetes. This trial will evaluate semaglutide in participants with early Type 1 diabetes. Participants will receive semaglutide, which mimics a hormone that lowers blood sugar and can improve heart and blood vessel function. Although most research focuses on Type 2 diabetes, early findings suggest it might also help those with Type 1 diabetes manage their condition.¹ ³ ⁴ ⁶ ⁷

Published Research Related to This Trial

Semaglutide, marketed as Rybelsus, is the first oral glucagon-like peptide receptor agonist approved by the FDA in 2019 for treating type 2 diabetes, highlighting its innovative delivery method.

This medication, taken once daily, aids in glucose control and weight management, potentially leading to improved health outcomes for individuals with type 2 diabetes.

Semaglutide Is a New Once-Daily Oral Medication to Treat Type 2 Diabetes.Blakely, KK., Weaver, K.[2021]

In a phase 3 trial involving 388 treatment-naive patients with type 2 diabetes, semaglutide significantly reduced HbA1c levels by 1.45% with 0.5 mg and 1.55% with 1.0 mg doses compared to placebo, indicating its efficacy in improving glycaemic control.

Semaglutide also led to significant weight loss, with reductions of 3.73 kg and 4.53 kg for the respective doses, while maintaining a safety profile similar to existing GLP-1 receptor agonists, with most adverse events being mild to moderate.

In a study of 20 patients with type 2 diabetes in Slovenia, oral semaglutide significantly reduced HbA1c levels and fasting plasma glucose, indicating its efficacy in improving glycaemic control.

Patients reported high satisfaction with the treatment, and while some experienced mild gastrointestinal side effects, the overall safety profile was considered good, suggesting that oral semaglutide is a promising option for diabetes management.
