Inhaled Insulin Shown as a Safe and Effective Replacement for Standard-of-Care in Children with Type 1 Diabetes

Findings Highlight Potential for Novel Approach to Insulin Delivery in Pediatric Population

CHICAGO, June 22, 2025 /PRNewswire/ -- Today, a new study demonstrates inhaled insulin as a safe and effective replacement for rapid-acting meal insulin in children with type 1 diabetes. Results from the INHALE-1 study were presented today as a symposium at the 85(th) Scientific Sessions of the American Diabetes Association(®) (ADA) in Chicago.

In the U.S., 304,000 children and adolescents have type 1 diabetes and depend on ongoing insulin treatment to regulate their blood glucose levels. Although most manage their condition through daily injections or insulin pumps, there is a growing demand for next-generation, tailored treatment approaches.

INHALE-1 evaluated the safety and efficacy of an inhaled insulin regimen (Afrezza) as a replacement for rapid-acting meal insulin in children with type 1 diabetes. The study included 230 patients aged 4-17, using basal injected insulin and randomized to either inhaled insulin or rapid-acting analogue for meals. The primary endpoint was the change in A1C at 26 weeks.

The findings indicate that inhaled insulin is safe and effective in children with type 1 diabetes, demonstrating glycemic control comparable to injected rapid-acting insulin. Inhaled insulin was also associated with less weight gain and slightly higher patient and parent preference scores.

"Inhaled insulin is the fastest acting insulin available and is a valuable alternative to injected analogue insulin. Afrezza should be available as an option to all children and adults with type 1 diabetes," said Michael J. Haller, MD, MS-CI, professor and chief of pediatric endocrinology, University of Florida, and lead author of the study. "These results will help clinicians better tailor treatment plans, ultimately improving patient satisfaction and overall outcomes."

Building on the findings of the inhaled insulin study, they are looking ahead to potential FDA approval and additional studies to evaluate inhaled insulin at diagnosis and in automated insulin delivery systems.
