Medpace Holdings Inc. said John Richardson and Anastasya Molodykh resigned from the board, effective Aug. 10.

The resignations were related to private equity firm Cinven Capital Management (V) General Partner Ltd. reducing its stake in the Cincinnati-based contract research organization, Medpace said in an SEC filing.

Earlier in August, Cinven Capital said it would sell 4.5 million common shares of Medpace at $55 apiece in a secondary offering.

In addition, Medpace said its board nominated and elected Fred Davenport Jr. and Cornelius McCarthy III as directors to fill the vacancies created by Richardson and Molodykh, respectively.

Davenport serves as a partner at the law firm of Murchison Taylor & Gibson PLLC and focuses on mergers and acquisitions, general corporate representation and estate planning.

McCarthy has served as managing director and CEO of Fairmount Partners LP since 2003 and focuses on healthcare and pharmaceutical outsourced services.
