Metformin Response During Meal Test for Type 2 Diabetes
(SCRAMBLED EGGS Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores how specific genes, such as SLC16A11, influence the response of people with type 2 diabetes to food and metformin, a common diabetes medication. Participants will consume a specially prepared meal and take metformin to determine if their body's responses vary based on genetic makeup. The trial includes two groups: one with the gene variant and another without. It suits adults who aren't currently taking diabetes medication and can consume a meal containing protein, carbohydrates, and fat. As an unphased trial, this study offers a unique opportunity to contribute to genetic research that may enhance future diabetes treatment.
Will I have to stop taking my current medications?
If you are currently taking any medications for diabetes or medications that affect blood sugar levels, you will need to stop taking them to participate in this study. The trial does not specify other medications, but planned changes to certain prescribed medications, like diuretics, are not allowed during the study.
Is there any evidence suggesting that metformin is likely to be safe for humans?
Research shows that metformin is a well-researched and commonly used medicine for treating type 2 diabetes. Studies have found that it is generally safe and most people tolerate it well. Common side effects include an upset stomach, nausea, and diarrhea, but these usually improve over time.
Metformin has been used safely to treat diabetes for many years. It also offers benefits like improving heart health and aiding in weight loss. Serious side effects, such as lactic acidosis—a rare but serious condition where too much lactic acid builds up in the blood—are uncommon.
Overall, metformin is considered a safe choice for many people with type 2 diabetes.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it explores how genetic differences, specifically the presence of the SLC16A11 risk allele, may affect the response to metformin, a common treatment for type 2 diabetes. Unlike standard treatments, which are generally applied universally, this approach could lead to more personalized diabetes management. By understanding how carriers of this allele respond to metformin compared to non-carriers, the trial aims to tailor treatments to individual genetic profiles, potentially improving efficacy and minimizing side effects.
What evidence suggests that metformin might be an effective treatment for type 2 diabetes?
Research has shown that metformin effectively treats type 2 diabetes by lowering blood sugar levels, even with small doses like 500 mg. In adults at high risk, metformin can reduce the chance of developing type 2 diabetes by about 23%. The Diabetes Prevention Program found that its benefits last for many years. Overall, metformin is a well-established and reliable treatment for managing blood sugar in type 2 diabetes.
In this trial, participants will divide into two groups: carriers of the SLC16A11 risk allele and non-carriers. Both groups will undergo a Mixed Meal Tolerance Test on Day 1 and Day 8, with metformin administered between these tests to assess its impact.678910Who Is on the Research Team?

Are You a Good Fit for This Trial?
This trial is for adults aged 18-79 who can consent to genetic research. It's not for those with kidney issues, contraindications to metformin, recent or planned medication changes, other study participation, intestinal malabsorption conditions, liver disease, pregnancy risk, or on diabetes medications.Inclusion Criteria

- Metformin
Trial Overview
The study tests how genes affect responses to a special meal and metformin (a common diabetes drug). Participants will eat a mixed meal and take metformin while researchers observe differences in response between gene carriers linked to type 2 diabetes.
