Positive Afrezza® Clinical Data from STAT Study Published in Diabetes Technology & Therapeutics

Study data show Afrezza provides greater improvement in postprandial glucose control than insulin aspart

WESTLAKE VILLAGE, Calif., Sept. 13, 2018 (GLOBE NEWSWIRE) -- MannKind Corporation (Nasdaq:MNKD) announced today that "Improved Postprandial Glucose with Inhaled Technosphere® Insulin Compared to Insulin Aspart in Patients with Type 1 Diabetes on Multiple Daily Injections: The STAT Study" has been published online in Diabetes Technology & Therapeutics.  

The STAT study is the first randomized, controlled study to assess diabetes control using continuous glucose monitoring and Afrezza® in individuals with type 1 diabetes. The dual primary endpoints were:

  • 24-hour glucose time-in-range (TIR)
  • Postprandial glucose excursions (PPGE), defined as the peak increase in glucose in the 1 to 4 hour post-meal period

This trial, supported by funding from MannKind Corporation, was a pilot study led by investigators at the Barbara Davis Center for Diabetes.  

Compared to standard of care for mealtime therapy, the per-protocol use of Afrezza (i.e. supplemental doses 1 and/or 2 hours post-meal), on average demonstrated:

  • Significantly increased glucose TIR by approximately 2 hours per day
  • Significantly reduced time in hyperglycemia > 180 mg/dL
  • Significantly lower PPGE 1 to 4 hours post-meal
  • Significant reductions in glucose as early as 60 minutes following Afrezza dose
  • Less hypoglycemia (as measured by time spent less than 60 mg/dL); notably, the average Afrezza-treated individual spent approximately 3 minutes per day with blood glucose values less than 50 mg/dL compared to approximately 12 minutes per day for aspart-treated individuals              

This is the first of a number of planned randomized trials, intended to evaluate the potential benefits of Afrezza (Technosphere Insulin) compared to the standard of care for mealtime plus basal insulin.

“I am very pleased to have helped develop the design of this novel trial (STAT) at the Barbara Davis Center for Diabetes, performed as a collaborative multi-center clinical trial with several other investigators around the country,” stated Halis Kaan Akturk, M.D., Assistant Professor of Medicine and Pediatrics, Barbara Davis Center for Diabetes, University of Colorado Denver and the principal investigator of the STAT study. “With the peer review publication of these data in Diabetes Technology & Therapeutics, we feel that our data supporting the unique time-action profile of Technosphere Insulin (Afrezza®) is helping us to better understand the potential advantages of a truly rapid-acting insulin delivery system for improving control of mealtime glucose. Specifically, individuals with type 1 diabetes, treated with Technosphere Insulin, demonstrated lower blood glucose as early as one hour after meals and, based on our analysis, supplemental dosing with Technosphere Insulin further improved the glucose control measured after meals. These data are the first to demonstrate that individuals living with type 1 diabetes may achieve significant improvement in postprandial glucose with Technosphere Insulin as a mealtime insulin, compared to standard of care, rapid-acting insulin analogs.”

“These new data significantly advance our understanding of the potential clinical benefits of Afrezza therapy for those living with type 1 diabetes,” stated David Kendall, M.D., Chief Medical Officer of MannKind Corporation. “We believe one of the key limitations to optimal glucose control and achieving better outcomes for people living with diabetes is their ability to control mealtime glucose levels. These data generated to date further support the view that Afrezza has the potential to be the treatment of choice for those individuals with diabetes who require alternatives that further improve mealtime glucose control. The completion of this proof-of-concept trial and peer-reviewed publication allows for broad sharing of these data with diabetes healthcare professionals.”

About Afrezza®
Available by prescription, Afrezza® (insulin human) Inhalation Powder is a rapid-acting inhaled insulin indicated to improve glycemic control in adult patients with diabetes mellitus. Afrezza consists of a dry powder formulation of human insulin delivered from a small and portable inhaler. Administered at the beginning of a meal, Afrezza dissolves rapidly upon inhalation to the lung and passes quickly into the bloodstream (in less than one minute). This rapid absorption allows Afrezza to begin reducing blood sugar levels within about 12 minutes of administration. Afrezza is available in 4-unit, 8-unit and 12-unit single-dose cartridges of insulin powder that can be used, as prescribed by a health care professional, in combination with other diabetes medications to achieve target blood sugar levels. For Afrezza doses exceeding 12 units, patients may use a combination of existing cartridge strengths. For more information on Afrezza, please visit
