What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores two methods for managing blood sugar during labor in pregnant individuals with type 1 diabetes. It compares a more relaxed blood sugar control range (70-140 mg/dL) with a stricter range (70-110 mg/dL) to determine if the relaxed method is equally safe for newborns. The trial targets those with type 1 diabetes using a hybrid closed-loop insulin system and planning a vaginal delivery. Participants should be near the end of their pregnancy and admitted for delivery at the study location. As a Phase 4 trial, the treatment is already FDA-approved and proven effective, aiming to understand its benefits for more patients.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What is the safety track record for insulin in this trial?

Research has shown that using insulin to manage type 1 diabetes during pregnancy is generally safe, though some risks exist. Studies have found that continuous insulin infusions can increase the likelihood of larger babies and early births. Additionally, there is a higher risk of low blood sugar, particularly early in pregnancy.

Automated insulin delivery systems have also undergone study. While promising, their effectiveness is still under evaluation. Some reported issues include early pregnancy loss and other complications. However, insulin remains widely used and FDA-approved for managing diabetes, indicating its general safety.

In this study, both groups will use insulin but aim for different blood sugar levels. The main goal is to determine if a more relaxed blood sugar target is as safe as a stricter one.12345

Why are researchers enthusiastic about this study treatment?

Researchers are excited about this trial because it explores different blood sugar management strategies for pregnant individuals with Type 1 Diabetes. Unlike the standard approach, which emphasizes strict blood sugar control (70-110 mg/dL), the experimental method allows for more permissive control (70-140 mg/dL). This approach could offer pregnant individuals more flexibility in managing their diabetes, potentially reducing stress and improving quality of life without compromising health outcomes. The trial aims to find out if this more relaxed target range is just as effective, which would be a significant shift in how diabetes is managed during pregnancy.

What evidence suggests that this trial's treatments could be effective for glucose management in pregnant individuals with type 1 diabetes?

Research shows that insulin therapy helps manage blood sugar levels in pregnant individuals with type 1 diabetes. In this trial, participants will join one of two groups: an intervention group with permissive blood sugar control (70-140 mg/dL) or a standard of care group with strict blood sugar control (70-110 mg/dL). Studies indicate that automated insulin delivery systems help pregnant women maintain their blood sugar within the target range more consistently, improving overall control. This is particularly beneficial at night, when managing blood sugar can be more challenging. Importantly, research has found no major differences in pregnancy outcomes between different types of insulin therapy. This suggests that insulin therapy, regardless of the method, effectively supports healthy pregnancies in those with type 1 diabetes.678910

What Are the Treatments Tested in This Trial?

Interventions

  • Insulin

Trial Overview

The PRISM-T1D study tests permissive glucose management (blood sugar levels between 70-140 mg/dL) against strict glucose management (70-110 mg/dL) in the delivery room, using insulin and continuous monitoring to see if there's a difference in newborns' blood sugar levels.
