Dr. Craig B. Thompson, Head of Sloan-Kettering, Is Sued The head of Memorial Sloan-Kettering Cancer Center was sued by the University of Pennsylvania, which says he breached his fiduciary duty to the school by using research he helped develop there to start his own company. The lawsuit against Dr. Craig B. Thompson, filed on Wednesday in Federal District Court in Manhattan, comes after a Dec. 13 complaint against him by the Leonard and Madlyn Abramson Family Cancer Research Institute at the university in Philadelphia. The suit also names the company Dr. Thompson formed, Agios Pharmaceuticals. Dr. Thompson studied cancer metabolism while he was scientific director of the institute, which was created by a $100 million donation from the Abramson family foundation to the university, according to the suits against him. Dr. Thompson's lawyer, Allan J. Arffa, and John Evans, a spokesman for Agios, did not immediately return calls for comment. The suit does not name Memorial Sloan-Kettering.
