SADDLE RIVER, N.J., May 7, 2007 -- PDI, Inc. (NASDAQ:PDII), a provider of commercialization services to the biopharmaceutical industry, today announced the launch of three new decision support products by its marketing services group subsidiary, TVG Marketing Research & Consulting. These TVG products have been developed in order to support pharmaceutical companies in better responding to market changes by providing both large and emerging companies with a greater level of insight into their customers and markets.

“The driving force behind these new introductions is the evolving needs of our clients to take their marketing research to the next level of insight,” said Kevin Connolly, Executive Vice President and General Manager, PDI Diversified Marketing Services. The products include Unified Market SimulatorSM, Message MaxSM and Brand Character PortraitSM Analysis.

Unified Market Simulator is TVG’s new approach to choice modeling that offers pharmaceutical companies the ability to make decisions based on a more comprehensive evaluation of potential product use. It provides a much richer level of data for TVG’s clients, including certain data not previously used in decision models, such as the impact of payors and patients. It offers key insights at a variety of strategic decision points, including evaluating licensing opportunities, valuation of pipeline products, clinical trial design, evaluating opportunities for new indication, and gauging impact of new competition.

Message Max was developed to enable clients to quickly and cost-effectively identify the best message configuration in the creation of detail aids and journal and direct-to-consumer (DTC) advertisements. “When developing the promotional message for any pharmaceutical product, whether new or existing, marketing teams often struggle with narrowing the field of choices to those that will yield the greatest return. Message Max is designed to solve those problems,” Mr. Connolly added.

The Brand Character Portrait Analysis provides a clear picture of the underlying motivations affecting product acceptance and delivers crucial insights into the emotional aspects of products. The results provide valuable input to the framing of promotional communication strategy and tactics, and provide product teams with the ability to build relationships, brand loyalty and advocacy for their brand.

Michael Marquard, CEO of PDI, said, “This new portfolio of marketing research products is another of a number of initiatives begun as part of our five-year strategic plan to transform PDI into a leading provider of commercialization services to the biopharmaceutical industry. Decision support services is an area we have identified as a key area for growth, and TVG’s long history of innovation and its ambitious plan to develop and introduce several new products this year will continue to strengthen PDI’s service offerings.”
