What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine if a new tool, InsuLearn, can help people with Type 1 diabetes manage their insulin doses more effectively than their usual method. Participants will use both InsuLearn and their regular insulin routine for 24 hours each to compare effectiveness. The study targets individuals who have had Type 1 diabetes for at least a year and currently use multiple daily insulin injections. As an unphased trial, it offers participants the chance to contribute to innovative diabetes management research.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop all current medications, but you cannot use NPH insulin or any non-insulin glucose-lowering agents like GLP-1 receptor agonists, pramlintide, and SGLT2 inhibitors. Other medications may be excluded if the investigator thinks they could interfere with the trial.

What prior data suggests that the InsuLearn intervention is safe for optimizing insulin doses?

Research shows that automated insulin delivery systems are generally safe for people with type 1 diabetes. Studies have found that these systems effectively manage blood sugar levels. They are easy to use, with few reports of serious side effects. Most adults with type 1 diabetes already use insulin shots several times a day, which is safe. Automated systems, such as InsuLearn, aim to enhance this process, potentially improving safety and effectiveness by reducing the risk of low blood sugar. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about InsuLearn for type 1 diabetes because it offers a personalized approach to insulin dosing. Unlike traditional methods where patients rely solely on their usual care for insulin calculations, InsuLearn uses advanced algorithms to tailor insulin doses specifically to the individual's needs. This innovative approach could lead to more precise blood sugar control, potentially improving daily management for those with type 1 diabetes.

What evidence suggests that InsuLearn might be an effective treatment for Type 1 Diabetes?

Research shows that automated insulin delivery systems, like InsuLearn, can greatly improve blood sugar control for people with type 1 diabetes. Studies have found that these systems help maintain blood sugar levels within the target range more frequently. This is often measured by Time-in-Range (TIR), which indicates the percentage of time blood sugar levels remain within safe limits. Additionally, InsuLearn has been linked to better overall blood sugar management and fewer instances of low blood sugar. In this trial, participants will experience both InsuLearn and their usual care methods. Early results suggest InsuLearn could provide similar benefits by adjusting insulin doses based on individual needs. ^{6 7 8 9 10}

Interventions

• InsuLearn

Trial Overview

The InsuLearn intervention is being tested against usual care in people with Type 1 Diabetes. It involves optimizing insulin doses based on data from a home monitoring period of four weeks. Participants are randomly assigned to start with either InsuLearn or their regular treatment.

How Is the Trial Designed?

Group I: InsuLearn→Usual Care Active Control 1 Intervention

During the first 24 hours of the hotel admission (visit 6), participants' insulin dose will be calculated by the InsuLearn, MD approved, report. The second 24 hours of the hotel admission (visit 7), participants will use their usual care method to calculate their insulin dose.

Group II: Usual Care→InsuLearn Active Control 1 Intervention

During the first 24 hours of the hotel admission (visit 6), participants' insulin dose will be calculated by their usual care method. The second 24 hours of the hotel admission (visit 7), participants will use the InsuLearn, MD approved, report to calculate their insulin dose.

Published Research Related to This Trial

Insulin treatment for diabetes can lead to various adverse events, including hypoglycemia, injection site issues, insulin allergy, and even increased risks of obesity and certain cancers, highlighting the need for better insulin formulations.

There is a significant opportunity to improve insulin therapies by developing formulations with more predictable absorption and kinetics, which could lead to better blood glucose control and reduced risks of complications.

Insulin Adverse Events. Ludvigsson, J.[2020]

The use of the Insulclock® device led to significant improvements in glycemic control for patients with uncontrolled type 1 diabetes, including a decrease in mean glucose levels and glucose variability, as well as an increase in time spent within the target glucose range.

Patients using the Insulclock® reported better treatment adherence and satisfaction, with a notable reduction in missed and mistimed insulin doses, suggesting that the device could enhance overall diabetes management.

SGLT2 inhibitors significantly lower key diabetes markers in type 1 diabetes patients, including glycated hemoglobin (HbA1c) and fasting plasma glucose, while also reducing body weight and total insulin dosage, based on a meta-analysis of 16 randomized controlled trials involving 7192 patients.

Importantly, the use of SGLT2 inhibitors does not increase the risk of hypoglycemia, urinary tract infections, or diarrhea, suggesting they can be safely integrated into treatment regimens for type 1 diabetes.

In a study of patients with type 1 diabetes, those using insulin glargine 300 U/mL (IG300) and insulin degludec (ID) showed similar long-term safety and efficacy compared to those continuing with insulin glargine 100 U/mL (IG100), with low rates of severe hypoglycemia and stable HbA1c levels over an average follow-up of 1.1 to 1.6 years.

Patients on IG100 experienced higher rates of severe adverse events and mortality (1.95%) compared to those on IG300 (0.7%) and ID (0.8%), suggesting that IG300 and ID may offer better safety profiles for long-term management of type 1 diabetes.

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 174 participants with Type 1 Diabetes Mellitus (T1DM) using insulin pumps, 84% reported experiencing at least one adverse event (AE), with an incidence rate of 3.42 AEs per person per year.

The most common AEs were related to infusion set/site issues (53%), cutaneous complications (43%), and pump malfunction (38%), indicating that while AEs are frequent, few factors predict their occurrence, emphasizing the need for patient education on managing these issues.

In a study involving 66 youth with type 1 diabetes, the use of the Insuflon injection port significantly improved glycemic control, as indicated by lower HbA1c levels compared to a control group at both 3 and 6 months.

Participants using the Insuflon saw their HbA1c levels decrease from 9.4% at the start to 8.7% at 3 months and 8.5% at 6 months, while no significant changes were observed in the control or alarm groups.
