FDA accepts MannKind's resubmission of AFREZZA NDA, sets PDUFA action date

MannKind Corporation (NASDAQ:MNKD) today announced that it has submitted, and the U.S. Food and Drug Administration (FDA) has accepted, MannKind's resubmission of its New Drug Application (NDA) for AFREZZA™ (insulin human [rDNA origin]) and classified it as a Class 2 resubmission. With the Class 2 designation, the FDA set a corresponding Prescription Drug User Fee Act (PDUFA) action date of December 29, 2010.

“We have worked diligently since March to prepare our resubmission and we are confident that we have addressed the requests that were outlined by the FDA”

In March 2010, MannKind received a Complete Response letter to its NDA for AFREZZA from the FDA requesting additional information. In response, MannKind has submitted clinical data from a recently completed efficacy study in patients with type 1 diabetes as well as updated pooled safety data related to AFREZZA and information on the comparability of MannKind's next-generation delivery system to the device that was used in pivotal clinical studies.

"We have worked diligently since March to prepare our resubmission and we are confident that we have addressed the requests that were outlined by the FDA," said Alfred Mann, Chairman and Chief Executive Officer. "We will continue to work closely with the FDA during this final stage of the review process. We firmly believe AFREZZA has the potential to address a poorly-met need in diabetes therapy. Our primary goal is to make this novel therapeutic option available to patients as soon as possible."
