Hillo to Remove Burden from your Life

Predictive BG and Insulin Dosing customized to each patient’s physiology and habits


Stéphane Bidet, CEO of Hillo

We spoke with Stéphane Bidet, CEO of Hillo —  

“Nicolas Caleca, CSO, and I founded this company to reduce the fear and unpredictability of managing T1D.

“My wife has T1D and I see her struggles. She is fearful of the complications of hyperglycemia so she generally overdoses with insulin. Thus, she has developed hypo-unawareness.  I have my alarm set for 2 AM and each night I check her BG to make sure she is not in a hypo.

Nicolas Caleca, CSO & Co-founder of Hillo

“Nicolas and I have a mutual friend that fears hypos and generally underdoses on insulin.  He knows that he is going to have complications but fears the loss of control with a hypo.

“To reduce fear we have to extend the time period in which BG predictions are accurate.

“This is hard because:

  • CGMs measure interstitial fluid which lag the level of glucose in your blood by 15-20 minutes.  
  • Insulin action curves vary considerably and even the fastest acting insulins take 30-45 minutes to start taking effect and their peak action takes about 90 minutes.  
  • The timing of glucose from food varies with the volume and mix of carbs, proteins, and fat
  • Each person has their own physiology, and this is influenced considerably by stress, sleep, sickness, other medications, and activity.

Our insight is that any glucose prediction algorithm must be individualized to every patient’s physiology and habits, and evolve based on their data.

“Our method combines pharmacokinetic and data-driven modeling.  Our goal was to extend the horizon for effective recommendations, and we have achieved a 2-hour horizon for accurate BG prediction.

  • Pharmacokinetic models are used to generate informative data regarding the past physiological state.
  • Data-driven models are machine learning algorithms, which provide glycemic prediction through the input data which includes glucose measurements along with the informative data from the pharmacokinetic model.

“Integrating a heart rate monitor into the data-driven model is an example of how personal activity data could help adjust BG predictions and associated insulin dosing recommendations.

Our approach is in contrast to the established artificial pancreas models which focus primarily on pharmacokinetic modeling. Their descriptive models have a 30-minute horizon for confident BG prediction.

Today, the number one issue patients with diabetes face is the decision-making process. What is needed is immediate assistance, which considers the patient’s specific and individual parameters,” said Eric Renard, MD, Division Chief of Diabetic Medicine @ CHU Montpellier. “With Hillo, I understand each patient’s glycemic response and can assist them with a customized solution. And this is unprecedented!

Hillo’s personalized decision support tools anticipate and avoid complications.  Initial trials have demonstrated outstanding accuracy for up to 120 minutes.
