Insulet Presents Promising Study Results for Fully Closed-Loop Automated Insulin Delivery System for Adults with Type 2 Diabetes

• Outcomes from EVOLUTION 2 study include 68% time in range with no boluses
• Diverse multicenter feasibility study highlights the promise of future Omnipod innovation to address unmet needs, improve outcomes, and redefine user and clinician experience

Insulet Corporation (NASDAQ:PODD) (Insulet or the Company), the global leader in tubeless insulin pump technology with its Omnipod® brand of products, has shared new clinical evidence related to the development of its first fully closed-loop (FCL)^A automated insulin delivery (AID) system for type 2 diabetes.

"Developing and bringing to market a fully closed-loop AID system for people with type 2 diabetes—one that delivers therapy effortlessly and adapts automatically with no mealtime interactions or adjustments—is more than evolutionary; it's revolutionary," said Dr. Trang Ly, MBBS, FRACP, PhD, Senior Vice President and Chief Medical Officer. "Our latest EVOLUTION study brings us another important step closer to addressing significant unmet needs^B while redefining both the provider and user experience."

Presented at the 19^th International Conference on Advanced Technologies & Treatments for Diabetes (ATTD) in Barcelona, Spain, EVOLUTION 2^C is the second in a series of feasibility studies supporting the development of an Omnipod fully closed-loop system.

This multicenter feasibility study was designed to drive rapid innovation, allowing investigators to evaluate multiple versions of the algorithm to support continued FCL system development. It included 24 adults in a highly diverse cohort from New Zealand, aged 16-70 years with type 2 diabetes using insulin (basal-bolus or basal-only, pumps or injections with HbA1c under 12.0%). The participants had lived with type 2 diabetes for an average of 16 years.

When using the final algorithm version of FCL with no boluses, the participants' time in range (TIR) increased to an average of 68%, a 24% improvement over standard injection therapy. Time Below Range (TBR) remained very low, with a median of 0.14% below 70 mg/dL—well under the American Diabetes Association's recommended threshold of less than 4%. No severe hypoglycemia or diabetic ketoacidosis (DKA) events were observed. Users experienced improved glycemic outcomes without compromising on low glucose events. The benefits were observed across a diverse set of participant characteristics including sex, ethnicity, baseline HbA1c, and body mass index. More than 90% of participants chose to continue into the ongoing extension phase, showing strong interest and positive experiences with the FCL system.

"The EVOLUTION 2 study results show a high time in range can be reached using an easy to use, intuitive system that is fully automated with no mealtime interactions. This adds to the growing evidence in support of automated insulin delivery and how innovations grounded in science can improve outcomes, reduce stress, and make diabetes a smaller part of everyday life," said Dr. Martin de Bock, Professor and Pediatric Endocrinologist at the University of Otago, Christchurch in New Zealand. Dr. de Bock served as Chief Investigator for the EVOLUTION 2 study.

Evolving toward a breakthrough

EVOLUTION 2 builds on the 2024 EVOLUTION 1^D feasibility study, which was the first evaluation of the Omnipod FCL algorithm in adults with type 2 diabetes. Participants in the EVOLUTION 1 study experienced significant improvements in TIR, from 52% to 65%, without boluses, representing more than three additional hours per day in target range with minimal hypoglycemia.

Insulet used these results to fine-tune the algorithm design, focusing on further simplifying the user experience and laying the groundwork for additional improvements studied with EVOLUTION 2.

The Company plans to start its pivotal study (EVOLVE) in 2026 to support a 510(k) filing in 2027 and a commercial launch in 2028.
