What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new insulin formulation, Portal Insulin U-500, to determine its safety and speed of action for people with Type 1 Diabetes. Researchers will compare the new insulin, administered directly into the abdomen (intraperitoneally), with other insulin types to assess which acts faster and lasts longer. Participants must have had Type 1 Diabetes for at least a year and regularly use an insulin pump or injections. As a Phase 1 trial, this research aims to understand how the treatment works in people, offering participants the opportunity to be among the first to receive this new insulin formulation.

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

Research has shown that Humulin R U-500, a concentrated insulin, is generally safe for people with diabetes who require large doses. Studies indicate that Humulin R U-500 helps control blood sugar levels in both adults and children with diabetes. It is important to remember that this insulin is much stronger than regular insulin, so using the correct dose is crucial.

Limited specific information exists on Portal Insulin U-500 (PI-U500) because it remains in early testing. Since this trial is in its first phase, researchers focus primarily on ensuring the treatment's safety. Early trials like this usually involve small groups and aim to find the best dose while checking for any side effects.

The trial compares PI-U500 with Humulin R U-500 and another insulin called Lyumjev. Both Humulin R U-500 and Lyumjev have been approved for use, suggesting they are safe when used correctly. Participants in the trial will receive different doses of PI-U500 to observe how their bodies respond.

In summary, while PI-U500 is still being tested, the use of other approved insulins in the trial provides some reassurance about the safety of similar treatments.12345

Why are researchers excited about this trial's treatments?

Portal Insulin U-500 is unique because it involves delivering insulin directly into the abdominal cavity, a method known as intraperitoneal administration. This is different from the usual subcutaneous injections used in standard treatments like Humulin R or Lyumjev. Researchers are excited about this approach because it might offer more rapid and consistent insulin absorption, potentially leading to better blood glucose control for people with Type 1 diabetes. This could mean fewer high and low blood sugar swings, improving overall quality of life.

What evidence suggests that this trial's treatments could be effective for Type 1 Diabetes?

Research shows that U-500 insulin can greatly help people with insulin resistance by improving blood sugar control. Studies have found that U-500 effectively stabilizes blood sugar levels in patients unresponsive to regular insulin doses. In this trial, participants will receive Portal Insulin U-500, tested by direct injection into the abdominal cavity. This method might alter the insulin's onset of action. Early results suggest this could be a promising way to manage blood sugar levels in people with Type 1 Diabetes.16789

Are You a Good Fit for This Trial?

This trial is for adults aged 18-60 with Type 1 Diabetes, using an insulin pump or multiple daily injections for at least 3 months. They must have low C-peptide levels, controlled HbA1c (≤8.5%), a BMI of 18.5-30 kg/m2, and weigh over 50 kg. Women should be non-pregnant, non-lactating, postmenopausal; men need to use contraception if not sterile.
