What is the purpose of this trial?

This trial tests Montbretin A, a new treatment for type 2 diabetes, to determine its safety and whether it causes fewer side effects than other diabetes medications. Participants will take increasing doses while researchers monitor their blood sugar and heart activity. Individuals with type 2 diabetes managed by diet, or healthy individuals without diabetes who eat three regular meals a day, may qualify. As a Phase 1 trial, participants will be among the first to receive this treatment, aiding researchers in understanding its effects in people.

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

Yes, you must stop taking your current medications, except for vitamins and/or birth control, to participate in the trial.

Will I have to stop taking my current medications?

Yes, you will need to stop taking your current medications, except for vitamins and birth control, to participate in this trial.

Is there any evidence suggesting that Montbretin A is likely to be safe for humans?

Research shows that Montbretin A (MbA) is being developed as a treatment for diabetes. However, specific safety information for MbA in humans is not yet available. This trial is in its early stages and primarily focuses on safety, marking the first time the treatment is tested in people to assess their tolerance. Early trials like this typically use small doses and closely monitor participants for any side effects.

Montbretin A, derived from a plant, has shown promise in lab studies for aiding diabetes. While it appears hopeful, scientists are still gathering information. Participants in the trial will begin with small doses, which will gradually increase to ensure safety, with close monitoring for any negative effects.

Although solid safety data is not yet available, this approach demonstrates a careful and cautious method of testing Montbretin A in humans. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Unlike the standard treatments for type 2 diabetes, which often include metformin, insulin, or sulfonylureas, Montbretin A (MbA) offers a fresh approach by potentially acting on different pathways. Researchers are excited about MbA because it is derived from a natural compound that might offer unique benefits, particularly in how it interacts with the body's glucose metabolism during meals. The treatment is administered in a controlled manner with standardized meals, possibly leading to more precise glucose control with fewer side effects. This new angle of targeting glucose levels in conjunction with meal intake presents a promising alternative to the current options.

What evidence suggests that Montbretin A might be an effective treatment for type 2 diabetes?

Research shows that Montbretin A (MbA), which participants in this trial will receive, could be a promising new treatment for type 2 diabetes. Derived from the montbretia plant, MbA is being developed to help control blood sugar levels. Early studies suggest that MbA might work by affecting certain processes involved in how the body handles sugar. Although limited data from human studies exist, the mechanism of MbA suggests it might have fewer side effects than current diabetes medications. This potential makes it an interesting option for future diabetes care. ^{1 2 3 4 6}

Trial Overview

The Montbretin A (MbA) clinical trial tests the safety of MbA in treating type 2 diabetes and if it has fewer side effects compared to existing treatments. Patients will take increasing doses of MbA over two weeks alongside standardized meals.

How Is the Trial Designed?

Group I: Intervention Experimental Treatment 1 Intervention

In this study, participants will receive increasing dosages of the Study Treatment (Montbretin A, MbA) at each treatment visit. The Study Treatment will be taken with a standardized meal (a meal that has specified quantities of carbohydrates, fats and proteins). At each visit, participants will receive one dose (in pill form) of MbA. As long as they are not experiencing any side effects, this dose will be gradually increased at each study visit (starting from 10 mg, 25 mg, 50 mg, 100 mg, 200 mg, to 300 mg MbA).

Montbretin A is already approved in Canada for the following indications:

Published Research Related to This Trial

Exenatide effectively improves glycemic control in patients with Type 2 diabetes by enhancing insulin secretion and suppressing appetite, leading to significant reductions in HbA1c and an average weight loss of 2 kg when used alongside metformin or sulfonylureas.

The treatment is generally well tolerated, with nausea being the most common side effect that decreases over time, and it poses a low risk of hypoglycemia, particularly when not combined with sulfonylureas.

Exenatide: incretin therapy for patients with Type 2 diabetes mellitus. Tahrani, AA., Piya, MK., Barnett, AH.[2019]

Incretin-based therapies, like exenatide, effectively manage Type 2 diabetes by enhancing insulin secretion in response to glucose, addressing key metabolic issues without a high risk of hypoglycemia.

Exenatide not only helps control blood sugar levels but also promotes weight loss and reduces caloric intake, making it a beneficial option for diabetes management.

A meta-analysis of 36 randomized trials involving GLP-1 receptor agonists for type 2 diabetes showed no significant increase in major cardiovascular events (MACE), with an overall odds ratio of 0.74, suggesting these medications are not harmful to heart health.

In placebo-controlled studies, GLP-1 receptor agonists demonstrated a significant reduction in MACE risk (odds ratio of 0.46), indicating potential cardiovascular safety, while results from active comparator studies showed no significant difference.

Incretin-based therapies, including GLP-1 receptor agonists and DPP-4 inhibitors, effectively lower blood sugar levels in type 2 diabetes while also improving beta-cell function, blood pressure, and lipid levels, with a low risk of causing hypoglycemia.

GLP-1 receptor agonists are associated with weight loss, whereas DPP-4 inhibitors are weight neutral, highlighting important differences in their clinical profiles for managing diabetes.

Intensive glucose control in type 2 diabetes can delay the onset and progression of both microvascular and possibly macrovascular diseases, highlighting the importance of early intervention and management strategies.

Combination therapy using insulin with oral medications like metformin can effectively normalize blood sugar levels while minimizing the need for intensive insulin regimens, although insulin therapy is associated with weight gain and hypoglycemia.

In a study involving approximately 32,800 users of exenatide, there was a modestly higher incidence of claims for thyroid malignancies compared to users of metformin or glyburide, but this association was not significant when focusing on inpatient claims.

Exenatide use was not linked to an increased risk of benign thyroid neoplasms or pancreatic cancer, suggesting it may be a safe option regarding these specific cancer risks.

Incretin-based therapies, such as DPP-4 inhibitors and GLP-1 agonists, provide effective glycemic control for type 2 diabetes patients without the weight gain often seen with traditional treatments, making them a favorable option for many.

Clinical trial data suggest that these therapies are safe, showing no negative effects on cardiovascular health, and their integration into treatment plans can enhance options for managing type 2 diabetes.

Type 2 diabetes is primarily caused by issues with insulin resistance and declining beta-cell function, making it crucial for healthcare providers to understand these mechanisms to tailor effective treatments.

Newer treatments like incretin therapy fill a gap in diabetes management by modulating glucose supply, and combining different antidiabetic agents can significantly enhance glycemic control for better patient outcomes.

Metformin is the first-line treatment for type 2 diabetes but often has limited efficacy over time, leading to the need for additional medications due to its gastrointestinal side effects and contraindications in certain patients.

Incretin-based therapies, particularly GLP-1 receptor agonists, are emerging as effective add-on treatments that can help achieve glycemic control while potentially offering cardiovascular benefits and improving β-cell function.

Incretin-based therapies, such as GLP-1 receptor agonists and DPP-4 inhibitors, not only help control blood sugar levels in type 2 diabetes but also have weight-neutral or weight-reducing effects, making them beneficial for patients with obesity-related diabetes.

These therapies may preserve beta-cell function, suggesting they could modify the disease's progression, and early use of GLP-1 receptor agonists may prevent diabetes in at-risk individuals or slow down the disease in those already diagnosed.
