MannKind Corporation Issues Statement on Lawsuit

VALENCIA, Calif.--(BUSINESS WIRE)--Nov 5, 2010 - MannKind Corporation (Nasdaq: MNKD) reported in its recent 10Q filing that a former employee in the regulatory affairs department, Mr. John Arditi, filed a lawsuit for wrongful termination claiming he was retaliated against for raising concerns about the company's clinical trials. The Company today stated that Mr. Arditi's employment was terminated by MannKind's Vice President - Worldwide Regulatory Affairs for legitimate reasons unrelated to his claim of retaliation.

Mr. Arditi's claims were thoroughly investigated by the company in an internal investigation as well as by an independent regulatory expert. The independent investigator was provided with unfettered access to the data related to the company's FDA submission for Afrezza® including the studies conducted in Bulgaria and Russia. Mr. Arditi provided information to the company and the independent investigator.

The independent investigator concluded that MannKind is, and was, taking prudent measures under Good Clinical Practice regulations to meet the requirements of Good Clinical Practices, and that there was no evidence of any deception or intent on the part of MannKind to deceive the FDA.

MannKind's Chief Financial Officer Matthew Pfeffer stated that, "We believe that Mr. Arditi's claims have no merit, and the company will vigorously defend the lawsuit in the normal course of business."
