New inhaled insulin combo aims to simplify diabetes care for teens
NCT ID NCT07224321
First seen Jun 27, 2026 · Last updated Aug 14, 2026 · Updated 4 times
Summary
This study tests a new approach for teens (ages 10-17) recently diagnosed with type 1 diabetes. They will use an inhaled insulin called Afrezza along with a long-acting injected insulin. The goal is to see if this combination helps keep blood sugar in a healthy range and is safe and satisfying for patients and families. The main part lasts 13 weeks, with an optional extension up to 26 weeks.
Why investors are watching
MannKind is testing Afrezza, its inhaled insulin, in children and teens newly diagnosed with type 1 diabetes. The trial combines Afrezza with a standard injected basal insulin, and it measures both blood sugar control and patient satisfaction. For a small company whose product is already approved in adults, a positive result in this younger, newly diagnosed group could open a much larger and earlier-use patient population.
If it works: A successful readout could support expanding Afrezza's label to include youth, giving MannKind a new revenue stream and a foothold in early-stage diabetes care. It could also strengthen the case for Afrezza as a first-line option rather than a later-stage add-on.
If it fails: The trial could fail to show adequate safety or efficacy in children, or the small single-arm design may produce results regulators find unconvincing. Trials in this age group often face recruitment and adherence challenges, and a delay or negative outcome would set back the company's expansion plans without any guarantee of recovery.

Inclusion Criteria: * Age 6 to \<18 years of age * Clinical diagnosis of stage 3 T1D, per the investigator. Stage 3 is defined as hyperglycemia, meeting ADA glycemic and clinical diagnostic criteria * Able to start the Afrezza-BI regimen within 21 days following T1D diagnosis (day 1 is based on the first insulin dose) * Forced Expiratory Volume in One Second (FEV1) \>80.0% of predicted Global Lung Function Initiative (GLI) value * Investigator believes that participant can be expected to follow the study protocol * No medical, psychiatric, psychosocial conditions, or medications being taken that in the investigator's judgment would be a safety concern for participation in the study Exclusion Criteria: * Prior insulin treatment for stage 2 T1D * In the judgment of the investigator, history of chronic lung disease, such as asthma, or chronic obstructive pulmonary disease, lung cancer, or any other clinically important pulmonary disease (e.g., cystic fibrosis, bronchopulmonary dysplasia) * Allergy or known hypersensitivity to human regular insulin * Smoking (includes cigarettes, cigars, pipes, marijuana, and vaping devices) within 3 months prior to screening and/or positive cotinine test for smoking * Positive urine pregnancy test for female subjects of childbearing potential
