What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this study is to determine whether an array of biosensors can noninvasively identify hyperglycemic or hypoglycemic events in persons diagnosed with diabetes through noninvasive detection of volatile organic compounds in exhaled breath.

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 safety data exists for diabetes sensing devices?

There is safety data available for diabetes devices like blood glucose meters, continuous glucose monitors, and insulin pumps, which shows that while adverse events are rare, they can occur and are important to monitor. Insulin pumps, for example, can have issues like pump failure or user error, leading to serious conditions like high or low blood sugar. Public databases like the FDA's MAUDE contain reports of these events, but more transparency and research are needed to improve safety. ^{1 2 3 4 5}

How does the Sensing Device treatment for diabetes differ from other treatments?

The Sensing Device for diabetes is unique because it provides continuous glucose monitoring, offering detailed data on glucose levels without the need for frequent finger pricks, unlike traditional glucose meters that provide only point sample information. ^{6 7 8 9 10}

What data supports the effectiveness of the Sensing Device treatment for diabetes?

Research shows that using a real-time glucose-sensor system can help improve blood sugar control in people with diabetes, leading to lower levels of glycated hemoglobin (a measure of long-term blood sugar control) and fewer episodes of low blood sugar. These findings suggest that the Sensing Device could be a useful tool for managing diabetes. ^{10 11 12 13 14}

Published Research Related to This Trial

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.

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.

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.

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.

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.
