New AI System Being Tested to Help People with Type 1 Diabetes Manage Insulin and Meals

A large European trial is underway to see if an artificial intelligence tool can help people on insulin injections achieve better blood sugar control by giving personalized dose suggestions and automatically estimating carbohydrates from food photos.

Key takeaways

  • The MELISSA trial is testing an AI system designed to give personalized insulin dose recommendations for people with Type 1 diabetes on multiple daily injections.
  • The system includes two main features: one that suggests basal and mealtime insulin doses, and another that estimates carbohydrates by analyzing photos of food.
  • Nearly 280 people with Type 1 diabetes are participating in this 22-week study across Europe to measure whether the system helps improve time spent in target blood sugar range.
  • This is a clinical trial in progress—results are not yet available, and the system is being studied to validate its effectiveness before wider use.

What Is the MELISSA Trial?

A new study called the MELISSA trial is investigating whether an artificial intelligence system can help people with Type 1 diabetes achieve better blood sugar control. The trial is taking place across multiple centers in Europe and involves nearly 278 people with Type 1 diabetes who use multiple daily insulin injections (MDI)—a common intensive insulin regimen.

The study is designed to run for 22 weeks and will measure whether the AI system helps people spend more time in their target blood sugar range (70–180 mg/dL, or 3.9–10.0 mmol/L). The trial is being conducted as a randomized controlled study, which is considered the gold standard for testing whether a treatment works.

How Does the MELISSA System Work?

The MELISSA system has two main AI-driven features. The first is called the Adaptive Basal-Bolus Advisor (ABBA), which provides personalized suggestions for basal insulin (the background insulin dose) and mealtime insulin doses based on a person's individual patterns and needs.

The second feature is an automated dietary assessment tool called goFOOD, which takes photos of food and uses AI to estimate carbohydrate content. This is designed to help people with Type 1 diabetes quickly and accurately know how many carbohydrates they are eating—information that is essential for calculating the right mealtime insulin dose.

How Is the Trial Designed?

Participants spend the first six weeks in an initialization period where the AI system learns about their individual insulin needs and eating patterns. After that, people are randomly assigned to either use the MELISSA system with their usual care, or to continue with their usual care alone.

The main question the trial is trying to answer is whether using the MELISSA system helps people spend more time in their target blood sugar range compared to usual care. Researchers are also tracking other measures of blood sugar control, how people feel about using the system, and safety information.

What Comes Next?

The MELISSA trial is currently underway, and results have not yet been published. The study also includes a small exploratory group of people with Type 2 diabetes to gather early information about whether the system might be helpful for them as well.

If the trial shows that the MELISSA system helps people achieve better blood sugar control, it could become a tool to support people with Type 1 diabetes who use multiple daily injections. Until results are available, this remains a promising area of research rather than a proven treatment.
