Exhibit 99.3

PDI Completes Sale of Its Commercial Services Business to Publicis Healthcare Communications Group

PDI Transitions to Pure Play Molecular Diagnostics Business and Changes Name to Interpace Diagnostics Group

Parsippany, NJ, December 22, 2015 -- PDI, Inc. (Nasdaq: PDII) announced the closing of the definitive asset purchase agreement under which Publicis Healthcare Communications Group has acquired PDI’s Commercial Services business (CSO) for the initial upfront cash payment of $25.5 million. The total gross cash proceeds are approximately $28.5 million, which includes the upfront cash payment as well as a closing working capital payment. The agreement was previously announced on November 2^nd, 2015 and on December 22, 2015 the transaction was approved by a majority of the PDI stockholders. Today, PDI changed its corporate name to Interpace Diagnostics Group (Interpace), Inc. and it will begin trading under the trading symbol IDXG on NASDAQ on December 23, 2015. The Company is using the proceeds from the transaction to pay off its existing senior commercial debt and for ongoing working capital to drive the growth of its molecular diagnostics operations.

“With the completion of the transaction, we are now a pure play in the expanding molecular diagnostics industry offering best in class solutions for determining the presence of certain cancers to clinicians and their patients. We are excited about our prospects in this growing and technologically advanced field of medicine. In addition to substantially greater gross margins and faster growth opportunities compared to our previous operations, we believe the pre-cancerous diagnosis area of molecular testing is an optimal area for Interpace to grow its diagnostics business. The pre-cancerous diagnostics market offers significant growth and strong patient value given the

substantial opportunity it affords to lower healthcare costs by reducing many unnecessary surgeries and avoid too frequent monitoring. We are keenly focused on growing our test volumes, reimbursement and revenue for our three commercialized innovative tests, bringing to market over the next year a fourth test, and building value for our shareholders,” said Nancy Lurker, President and CEO.
