Second graph under Other Results subhead, second sentence should read: The event rate of severe hypoglycemia was also lower in the AFREZZA-Gen2 group (8.05 events per 100 subject-months) than in the insulin aspart group (14.45 events per 100 subject-months); however, this difference was not statistically significant (p=0.1022) (sted The event rate of severe hypoglycemia was also lower in the AFREZZA-Gen2 group (8.05 events per subject-month) than in the insulin aspart group (14.45 events per subject-month); however, this difference was not statistically significant (p=0.1022)). The corrected release reads: MANNKIND REPORTS POSITIVE DATA FROM A PHASE 3 CLINICAL STUDY OF AFREZZA IN PATIENTS WITH TYPE 1 DIABETES MannKind Corporation (Nasdaq: MNKD) today announced positive preliminary results from Study 171, 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 (Gen2) inhaler (also known as the Dreamboat™ inhaler), in patients with type 1 diabetes. Highlights AFREZZA-Gen2, compared to insulin aspart, showed:
- Non-inferior decreases in A1c levels;
- Significantly less hypoglycemia;
- Significant decreases in fasting blood glucose levels; and
- Significant weight advantage.
Study 171Study 171 was an open-label study involving 518 patients with type 1 diabetes on basal/bolus insulin therapy who were studied at sites in the United States, Russia, Ukraine and Brazil. After a four-week run-in period to optimize their basal insulin, patients entered a 24-week treatment period in which they were randomized in one of three ways:
- Continuing on subcutaneous insulin aspart in combination with a basal insulin (170 patients);
- Switching to AFREZZA administered using the Gen2 inhaler in combination with their basal insulin (174 patients); or
- Switching to AFREZZA administered using the MedTone inhaler in combination with their basal insulin (174 patients).
The proportion of subjects achieving A1c target levels ≤7.0% or ≤6.5% at the end of the 24-week treatment period was less in the AFREZZA-Gen2 group than in the insulin aspart group; however, among patients who achieved A1c levels ≤7.0% and ≤6.5% at the end of the 24-week treatment period, the event rates for overall hypoglycemia (mild, moderate and severe) were all significantly lower in the AFREZZA-Gen2 group than in the insulin aspart group.There was also a significant difference in weight outcomes. Patients in the AFREZZA-Gen2 group lost an average of 0.39 kg over the treatment period compared to an average gain of 0.93 kg in the insulin aspart group (p=0.0102). The main safety objective of this study was to compare changes in FEV 1 (forced expiratory volume in one second) from randomization to week 24 between the AFREZZA-Gen2 and AFREZZA-MedTone groups. Over this period, there was an insignificant difference of 0.01 L in mean change in FEV 1 between the two AFREZZA groups (p=0.5364). Over the same 24-week treatment period, the decrease in FEV 1 seen in the AFREZZA-Gen2 group was slightly greater than that seen in the aspart group (0.03 L). After cessation of the treatment period, FEV 1 values in both AFREZZA groups increased, so that by the follow-up visit at week 28 there were virtually no differences in FEV 1 among the three treatment groups. In general, treatment with AFREZZA was well-tolerated over 24 weeks by subjects with type 1 diabetes. The incidence of serious adverse events related to study drug was similar in the AFREZZA-Gen2 (2.3%), AFREZZA-MedTone (2.9%) and insulin aspart (1.8%) groups. There were no serious cardiovascular events reported in this study. The most common drug-related adverse event was cough, reported by 30.5% of AFREZZA-Gen2 patients, 20.8% of AFREZZA-MedTone patients and 0% of insulin aspart patients. Cough was predominantly dry, intermittent, and usually occurred within 10 minutes of inhalation. The incidence of cough was highest during the first week of the treatment period and diminished quickly thereafter. The discontinuation rate due to cough was low (AFREZZA-Gen2: 5.7%; AFREZZA-MedTone: 2.9%; insulin aspart: 0%).
These preliminary results are subject to further analysis.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 bloodstream. Peak insulin levels are achieved within 12 to 14 minutes of administration, effectively mimicking the release of meal-time insulin observed in healthy individuals, but which is absent in patients with diabetes. About MannKind Corporation MannKind Corporation (Nasdaq: MNKD) focuses on the discovery, development and commercialization of therapeutic products for patients with diseases such as diabetes. Its lead product candidate, AFREZZA ®, has completed Phase 3 clinical trials.
