Insulet Presents Positive Clinical Trial Results for the Omnipod® Horizon™ Hybrid Closed-Loop System at the American Diabetes Association's 78th Scientific Sessions

Insulet Corporation (NASDAQ:PODD) (Insulet or the Company), the leader in tubeless insulin pump technology with its Omnipod® Insulin Management System (Omnipod System), today announced that positive results from the most recent clinical trial of the Omnipod® Horizon™ Automated Glucose Control System (Omnipod Horizon System) were presented during the American Diabetes Association (ADA) 78th Scientific Sessions in Orlando. The study demonstrated that the Omnipod Horizon System performed well and was safe for over five days of use in adults, adolescents, and children with type 1 diabetes.1-3

The study was conducted in a supervised hotel setting under free-living conditions with unrestricted meals and moderate-intensity exercise and included patients who use multiple daily injections or traditional tubed insulin pumps as their standard therapy. Study participants spent significantly less time in hypoglycemia, more time in the target glucose range and had better overnight glycemic control compared to their standard therapy. The investigational device includes features that allowed study participants to customize their diabetes management by adjusting their target blood glucose levels and insulin delivery.

“We recognize that everyone’s treatment needs are different, and the Omnipod Horizon System provides individualized diabetes management to address real world challenges,” said Dr. Jennifer L. Sherr, MD, PhD, of Yale University School of Medicine. “One of the important features is the ability for users to tailor the system for exercise and high fat meals to maintain good glycemic control.”

During the study, glucose control was maintained in the target range (70 to 180 mg/dL) between 69% and 79% of the time overall, and between 74% and 85% of the time during the overnight period, across all age groups. Hypoglycemia was very low overnight, ranging from 0.7% and 1.3% of the time, across age groups.

“In the era of personalized medicine, Insulet is committed to bringing our innovative technology to the global diabetes community and our clinical data give us confidence that the Omnipod Horizon System will be a significant advancement in diabetes management,” said Dr. Trang Ly, Senior Vice President and Medical Director. “We are very pleased that for the second consecutive year, Omnipod Horizon System research was highlighted in the official ADA Press Program based upon its overall excellence in furthering research and advancing treatment for people with diabetes.”
