Sam Waksal of Kadmon Pharmaceuticals

Kadmon, the drug company founded by Sam Waksal of ImClone and Martha Stewart fame, is starting to look more and more like its founder's last company.

CNBC reported Wednesday that Sam Waksal will step aside as chief executive of closely held Kadmon as the company plans to file for an initial public offering. Because of Waksal's ban from serving as an officer of a public company that stemmed from his insider trading charges, his brother, Harlan, is joining the company as president and CEO.
