MannKind Corporation (Nasdaq: MNKD) today announced the resubmission on October 13, 2013 of a new drug application (NDA) to the U.S. Food and Drug Administration (FDA) seeking approval for the marketing and sale of AFREZZA ® (insulin human [rDNA origin]) Inhalation Powder with an indication to improve glycemic control in adults with type 1 or type 2 diabetes. The resubmission is based on the entire data set from the extensive AFREZZA clinical development program and particularly the positive results from two recent Phase 3 trials, one in patients with type 1 diabetes (study 171) and one in patients with type 2 diabetes (study 175). “We designed the recent studies with input and guidance from the FDA, and both achieved their primary efficacy endpoints and safety objectives,” said Alfred Mann, Chairman and Chief Executive Officer of MannKind Corporation. “I am very proud of our team for completing an extensive submission on a very ambitious schedule. We will continue to work with the FDA to bring AFREZZA to market for the millions of diabetes patients in the United States who might benefit from this novel product.” About AFREZZA® AFREZZA ® (uh-FREZZ-uh) is a novel, ultra rapid-acting mealtime insulin therapy developed by MannKind Corporation to improve glycemic control in adult patients with type 1 or type 2 diabetes.
