Nicole S. Jones has been named general counsel of the combined company created by the health insurer Cigna Corp.’s purchase of pharmacy benefit manager Express Scripts Holding Co., which was approved by the antitrust division of the U.S. Department of Justice last month.

Bloomfield, Connecticut-based Cigna announced last Thursday its new leadership team under  David Cordani, president and CEO, who also would hold the same post in the combined company. Express Scripts President and CEO Tim Wentworth would lead the health services business as president of Express Scripts and Cigna Services, subject to regulatory approval of the merger, which is expected to close by the end of this year.
