What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new treatment that involves implanting a special product under the skin to help people with Type 1 Diabetes who can't sense low blood sugar. The goal is to see if this can help their bodies produce insulin naturally and manage blood sugar levels more effectively.

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

The trial protocol does not specify if you need to stop your current medications. However, it mentions that participants should have a stable diabetic treatment, which might mean you can continue your current regimen.

How does the VC-02 treatment for Type 1 Diabetes differ from other treatments?

The VC-02 treatment is unique because it combines different components to potentially protect insulin-producing cells from immune system attacks and inflammation, which is not a standard approach in current Type 1 Diabetes treatments. ^{1 2 3 4 5}

What data supports the effectiveness of the VC-02 drug for Type 1 Diabetes?

Research shows that adding liraglutide, a component similar to those in VC-02, to insulin treatment can improve blood sugar control and help with weight management in people with Type 1 Diabetes. ^{6 7 8 9 10}

Published Research Related to This Trial

In the Phase III DEFEND-2 trial involving 179 patients (including 54 adolescents), otelixizumab did not significantly preserve C-peptide secretion in patients with new-onset Type 1 diabetes, showing a change from baseline that was not statistically significant (P=0.051).

The study found that the efficacy and tolerability of otelixizumab at a 3.1 mg dose were similar to previous results from DEFEND-1, indicating that this dose was ineffective for both adults and adolescents, and further research is needed to explore higher doses and their mechanisms.

In a study of 50 children and adolescents with poorly controlled type 1 diabetes, switching to the IDegAsp insulin co-formulation led to a significant reduction in self-reported mild to moderate hypoglycemic episodes after one year.

While the overall hemoglobin A1c levels remained unchanged, the frequency of diabetic ketoacidosis (DKA) attacks decreased from 11 to 4, suggesting that IDegAsp may enhance clinical management for patients struggling with frequent hypoglycemia and DKA.

In a 52-week study involving 1,398 adults with type 1 diabetes, adding liraglutide to insulin therapy significantly reduced HbA1c levels and insulin requirements, with reductions in body weight observed across all liraglutide doses compared to placebo.

However, the addition of liraglutide was associated with increased rates of symptomatic hypoglycemia and a significant rise in hyperglycemia with ketosis for the highest dose, which may limit its clinical use in this population.
