What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to test a new device that detects blood sugar levels by analyzing breath. It targets individuals with type 1 diabetes to determine if the device can identify high or low blood sugar without needing a blood sample. The trial seeks children and teens, aged 12-19, who already use a specific type of glucose monitor and reside in or near Indianapolis, IN. As an unphased trial, this study provides a unique opportunity to contribute to innovative diabetes research without the constraints of traditional clinical trial phases.

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

The trial information does not specify whether you need to stop taking your current medications. It seems focused on monitoring glucose levels with a device, so you may not need to change your medication routine.

What prior data suggests that this sensing device is safe for diabetic children?

Research has shown that diabetes sensing devices, like the one in this trial, are generally safe to use. Studies have found that people usually tolerate these devices well. They function similarly to continuous glucose monitors (CGMs) that many people with diabetes already use.

For this specific device, current safety data reports no serious side effects. However, users should be aware of small parts that could pose a choking hazard. Ensuring the device functions correctly is crucial to avoid missing signs of very low blood sugar.

Overall, evidence suggests these devices are safe, but users should carefully follow all instructions to ensure safety. ^{1 2 3 4 5}

Why are researchers excited about this trial?

The Sensing Device is unique because it offers a noninvasive way to monitor blood glucose levels, unlike traditional methods that require finger pricks or continuous glucose monitors with needles. This wearable sensor allows users to simply breathe into it, making glucose monitoring more comfortable and accessible, particularly for children with diabetes. Researchers are excited about this innovation as it could greatly enhance the quality of life for diabetic patients by reducing the pain and inconvenience associated with frequent blood glucose testing.

What evidence suggests that this sensing device is effective for detecting glucose levels in diabetes?

Research has shown that continuous glucose monitoring (CGM) devices greatly assist people with diabetes in managing their blood sugar levels. Studies have found that these devices lead to better blood sugar control and higher user satisfaction. CGMs enable individuals to detect high or low blood sugar levels, allowing them to act before issues arise. This reduces the risk of low blood sugar (hypoglycemia) or high blood sugar (hyperglycemia). In this trial, participants will use a sensing device that aims to achieve similar results by monitoring blood sugar changes through breath, offering a noninvasive way to manage diabetes. ^{6 7 8 9 10}

Insulin pump therapy (CSII) is crucial for managing type 1 diabetes, but it carries risks of serious complications like hyperglycemia and hypoglycemia due to various factors including pump failures and user errors.

There is a lack of transparency and sufficient data on the safety and long-term efficacy of insulin pumps, highlighting the need for better regulatory practices and more public funding for research to improve user education and prevent adverse events.

A study involving 15 patients revealed that the FreeStyle® Libre glucose sensor can cause allergic contact dermatitis, primarily due to its adhesive component.

Isobornyl acrylate was identified as a significant allergen in these cases, with 12 out of 13 tested patients showing sensitization to it, highlighting the need for awareness of potential allergic reactions to this medical device.

A study involving 549 participants from the TuDiabetes.org online community found that 75 reported device-related adverse events, with nearly half requiring intervention, highlighting the potential for online networks to capture real-world device issues.

Only 4% of these adverse events were reported to the FDA, suggesting that online participatory surveillance can provide more comprehensive outcome data compared to traditional reporting methods, which often lack detailed information.

Glucose meter evaluations show that while many devices perform well according to standards, there are still significant malfunctions reported, with 10,837 adverse events documented in the FDA's MAUDE database in just the first 7 months of 2018.

Using reliability growth management techniques could help reduce the failure rates of glucose meters by analyzing and addressing the issues highlighted in the MAUDE database.

The use of a real-time glucose-sensor system significantly improved glucose control in patients with type 1 and type 2 diabetes, leading to reduced HbA1c levels and fewer hypoglycemic episodes.

Despite some technical challenges, particularly in type 2 diabetes patients, the positive outcomes suggest that glucose sensors could be an effective educational tool for managing diabetes, warranting further research in larger studies.
