NEW YORK (AP) A former hedge fund portfolio manager's New York trial is scheduled for January. He's charged with persuading a medical professor to leak secret data from an Alzheimer's disease trial.

Federal Judge Paul Gardephe (GAHR'-duh-fee) rescheduled the trial of Mathew Martoma on Tuesday. It originally was planned for November.

Martoma has pleaded not guilty to an indictment brought against him after his arrest a year ago.

Prosecutors say he tried to get inside information from more than 20 doctors. The government says the information enabled other investment professionals at the hedge fund founded by Steven A. Cohen to earn a quarter-billion dollars illegally.

Prosecutors say the crimes were carried out from 2006 to 2008 while the Boca Raton, Fla., resident worked at Cohen's SAC Capital Advisors.
