What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new wearable insulin pump designed to help people with type 1 diabetes manage blood sugar levels during sleep. The device, called the Luna System or Luna Diabetes patch pump, works with a continuous glucose monitor to deliver quick insulin doses at night. It aims to reduce high blood sugar levels that occur during sleep and upon waking. Participants should have type 1 diabetes, experience frequent high blood sugar at night, and already use a real-time glucose monitor.

As an unphased trial, this study provides an opportunity to contribute to innovative diabetes management solutions.

Will I have to stop taking my current medications?

The trial does not specify that you need to stop taking your current medications, but you must have a stable dose of any non-insulin glucose-lowering drugs or weight loss medications for at least 30 days before starting. You cannot use certain medications like hydroxyurea or corticosteroids that affect blood sugar levels during the study.

What prior data suggests that this device is safe for use during sleep?

Research shows that the Luna System, a patch pump worn overnight, helps manage blood sugar levels during sleep. It works with a continuous glucose monitor (CGM) to deliver quick insulin doses when needed.

In earlier studies, participants using this device showed promising results in managing diabetes. The Luna System automatically adjusts insulin doses, offering an easier alternative for those who use insulin pens and seek overnight management.

Although specific safety details from the studies are not provided, the Luna System's presence in a trial suggests confidence in its safety. Clinical trials typically begin with a solid understanding of a treatment's safety before testing it on people. If it is in a trial, it has passed initial safety checks.

Overall, the Luna System appears to be a well-tolerated option for managing insulin overnight, based on its design and its testing in humans. ^{1 2 3 4 5}

Why are researchers excited about this trial?

The Luna System for Diabetes is unique because it uses an episodic overnight patch pump that patients wear during sleep. Unlike traditional insulin pumps or injections that require continuous attention throughout the day, this system offers a more convenient, hassle-free way to manage blood sugar levels overnight. Researchers are excited about this approach because it could improve glucose control during sleep, a time when managing diabetes can be particularly challenging, potentially reducing the risk of nocturnal hypoglycemia and providing a better quality of life for patients.

What evidence suggests that the Luna System is effective for lowering blood sugar during sleep?

Research has shown that the Luna System, a wearable insulin pump, can help manage blood sugar levels during sleep. In this trial, participants will wear the Luna System overnight alongside their usual basal/bolus therapy. Early results from previous studies showed positive outcomes, including a 10% increase in the time patients' blood sugar levels stayed within the target range and a 15% decrease in the time spent with high blood sugar levels. The system works with continuous glucose monitors (CGMs) to automatically provide the right amount of insulin overnight, helping to keep blood sugar levels stable. These findings suggest that the Luna System may benefit those who struggle with high blood sugar levels at night. ^{1 2 3 6 7}

Are You a Good Fit for This Trial?

This trial is for adults over 18 with Type 1 Diabetes who've been on a stable insulin regimen for at least a month. They must use rapid-acting insulin, have used CGM systems for three months or more, and experience high blood sugar at night frequently. Participants need to be iPhone users and cannot start new glucose-lowering or weight loss drugs within the last month.

Inclusion Criteria

I have been using a CGM device for over 3 months with consistent use in the last month.

I have been on a stable dose of my diabetes medication for at least 30 days.

I have been diagnosed with Type 1 Diabetes for over 6 months and on a stable insulin plan for over 30 days.

Published Research Related to This Trial

The mylife™ OmniPod® patch pump showed low accuracy in delivering insulin, especially at lower doses, with only 18.6% to 96.0% of bolus doses meeting the ±5% accuracy threshold, compared to the MiniMed® 640G which had higher accuracy rates, particularly at larger bolus volumes.

Both insulin pumps demonstrated better accuracy at higher bolus volumes and later delivery times, but overall, clinicians should be cautious about the variability in insulin delivery, particularly for patients requiring low doses, as this could impact treatment effectiveness.

Over 40% of insulin pump users experience adverse events each year, with hyperglycemia and ketosis being the most common outcomes, particularly linked to infusion set failures.

The review emphasizes the need for continuous education and support for patients using insulin pumps to enhance their experience and potentially reduce the frequency and severity of adverse events.

In a study involving four type 1 diabetics with long-standing diabetes, the use of a portable open-loop insulin infusion system for four months led to improved metabolic control, evidenced by lower blood glucose levels and reduced urinary glucose excretion.

All patients reported feeling well during the treatment, and while there were some technical complications, the overall safety profile was favorable, indicating that this method of insulin delivery can be effective for managing diabetes.

Insulin pump therapy (CSII) significantly improves glycemic control in children with diabetes, leading to reductions in hypoglycemia, diabetic ketoacidosis (DKA), and mean HbA1c levels, while also enhancing quality of life and patient responsibility.

Using the pump at night for young children (ages 7-10) allows for better nocturnal glycemia management without the risks associated with daytime use, highlighting the importance of tailored education for families in effectively managing diabetes.

A systematic review and meta-analysis of four studies involving 272 patients with type 1 diabetes showed that predictive low glucose suspend (PLGS) systems significantly reduce the risk of nocturnal hypoglycemia, with a decrease from 27.8% to 19.6% in hypoglycemic episodes during overnight periods.

The analysis indicated that PLGS systems are associated with an 8.8% lower risk of experiencing hypoglycemia compared to non-PLGS periods, highlighting their effectiveness in managing blood sugar levels during the night.
