George Yancopoulos, the president and top scientist at Regeneron Pharmaceuticals, took home approximately $268 million in 2017, based on calculations of his actual realized stock gains disclosed in a new federal filing.

The big picture: That's the largest pay package of any health care executive from 2017 so far. Yancopoulos, who is the main inventor of Regeneron's prescription drugs like Eylea and Praluent, made almost three times as much as Regeneron's CEO, Leonard Schleifer, who made $95 million last year.
