[MannKind Corp.] – Valencia-based MannKind Corp. announced Tuesday that it reached a final resolution of the arbitration proceedings initiated by John Arditi, MannKind’s former Senior Director-GCP, Regulatory Affairs. During his employment with MannKind, Mr. Arditi played a key role in preparing clinical sites for FDA inspection and was responsible for the company’s GCP compliance audit program.

In connection with the resolution of the matter, Mr. Arditi withdrew his claims against MannKind for violation of the New Jersey Conscientious Employee Protection Act, wrongful discharge, breach of contract, breach of the implied covenant of good faith and fair dealing, intentional infliction of emotional distress and defamation. In return, MannKind withdrew its claims against Mr. Arditi. Neither party paid any monetary consideration to the other party in connection with the resolution of the arbitration proceedings.

“I do not believe there was fraud or scientific misconduct on the part of investigators nor do I believe there is any question regarding the reliability and integrity of the data collected in MannKind’s clinical trials while I was employed. I am proud that I was part of a team that achieved full GCP compliance with respect to the Afrezza new drug application during my employment,” said Mr. Arditi.

Alfred Mann, Chairman and Chief Executive Officer of MannKind, added, “Peter Richardson, Patricia Mayer and the entire team set extremely high standards for quality in our earlier clinical program, and then exceeded those standards in a professional and diligent manner. I have been emphasizing the importance of getting our current Phase 3 clinical studies underway in a timely manner, but I do so knowing that we have an unwavering commitment to quality.”
