  Treatment of Adults with Diabetes

Business Wire

VALENCIA, Calif. -- October 14, 2013

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.”


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. It is a drug-device combination
product, consisting of AFREZZA Inhalation Powder delivered using a small,
discreet and easy-to-use inhaler. Administered at the start of a meal, AFREZZA
Inhalation Powder dissolves immediately upon inhalation to the deep lung and
delivers insulin quickly to the bloodstream. Peak insulin levels are achieved
within 12 to 15 minutes of administration, compared to 45-90 minutes for
injected rapid acting insulin analogs and 90-150 minutes for injected regular
human insulin.
