MannKind Corporation (Nasdaq: MNKD) today announced that all follow-up visits have been completed for the patients enrolled in Study 175, a Phase 3 clinical study of AFREZZA ® (insulin human [rDNA origin]) inhalation powder, an investigational, ultra rapid-acting mealtime insulin therapy, administered using MannKind’s next-generation inhaler. MannKind expects to release data from this study later this summer. Study 175 assessed AFREZZA using the next-generation inhaler in patients with type 2 diabetes whose disease is inadequately controlled on metformin with or without a second or third oral medication. After a run-in period during which the subjects remained on their oral medication, 353 patients were randomized to additional treatment with AFREZZA or to Technosphere® inhalation powder (placebo). The study also had a titration period, followed by a 12-week evaluation period to assess HbA1c levels. About AFREZZA® AFREZZA® is a novel, ultra rapid acting mealtime insulin therapy being developed by MannKind Corporation for the treatment of adult patients with type 1 or type 2 diabetes for the control of hyperglycemia. It is a drug-device combination product, consisting of AFREZZA Inhalation Powder, pre-metered into single-use cartridges, and a light, discreet and easy-to-use inhaler. Administered at the start of a meal, AFREZZA dissolves immediately upon inhalation and delivers insulin quickly to the blood stream. Peak insulin levels are achieved within 12 to 14 minutes of administration, mimicking the release of meal-time insulin observed in healthy individuals. To date, the AFREZZA clinical program has involved 61 different clinical studies and over 5,600 adult patients.
