MEDIDATA SOLUTIONS ACHIEVES RECORD RESULTS IN 2007

EDC Company Reaches Another Milestone with Enterprise and Mid-Market Customer
Commitments, CRO and Technology Provider Partnerships and
Progressive Product Vision

NEW YORK, NY – March 3, 2008 – Medidata Solutions, a leading global provider of electronic clinical data capture (EDC), management and reporting solutions, today announced record results for 2007. Medidata estimates that its revenues for 2007 increased by more than 60 percent year-over-year and that it achieved the highest revenue quarter in the company’s history in Q4. The company’s continued growth in 2007 was driven by the introduction of Medidata Rave® 5.6, significant customer wins, extended relationships with existing customers and new and expanded partnerships with contract research organizations (CROs). While supporting its growth with significant resource expansion, Medidata also further strengthened its position as an industry leader through strategic collaborations with key technology providers.

Increasing Market Acceptance
From big pharmas to mid-market companies to smaller biotechs, Medidata in 2007 further demonstrated its position as a key clinical technology partner. Medidata secured a total of 42 new Rave customers in 2007, including enterprise deals with Array BioPharma, Elan Pharmaceuticals, Inc., H. Lundbeck A/S, Orion Corporation and Wyeth Pharmaceuticals. Medidata also extended existing relationships with 35 customers.

Partnering with CROs and Other Service Providers
Medidata continued to expand its partnerships with CROs and other service providers through its ASPire to Win® program which provides training and support to CROs in the implementation of Medidata Rave, the company's primary product offering for conducting clinical trials. Seven ASPire to Win partners were added in 2007, including Chiltern Ltd, Eliassen Group, PAREXEL International and EPS, one of the largest CROs in Japan. In addition, Medidata reached a one-year partnership milestone with INC
Research as well as a two-year milestone in its partnership with ICON.

Collaborating for End-to-End Clinical Research
With a focus on enabling end-to-end clinical research solutions, Medidata established strategic partnerships with several key technology companies during the past year. These partnerships lead to successful integrations between Medidata Rave and TrialSpace Designer XCP™, a clinical trial design and protocol authoring tool from FastTrack, and SAS® Drug Development, a data management and analysis solution from SAS Institute Inc. Medidata also joined forces with PHT, an electronic patient diary company, to integrate PHT’s LogPad® ePRO system with Medidata Rave, a product integration that
was implemented by Sucampo Pharmaceuticals.

Focusing on Innovation
With this year’s introduction of Medidata Rave 5.6, the latest version of the company’s electronic data capture, management and reporting system, customers and partners benefited from enhanced ease of use for sites and sponsors, additional features and functionality and improved performance. With these enhancements, Medidata Rave is better positioned to serve as the focal point for the aggregation and dissemination of our clients' clinical trial data – handling both EDC and clinical data management system (CDMS) tasks on one system. Medidata Rave 5.6 also builds on Rave’s scalability, multiple language capabilities and study design modules, streamlining data collection at clinical sites for access by the client's entire clinical study team.

Reaching the Customer
In 2007, Medidata continued to expand its customer-focused initiatives, directly reaching customers through a range of webinars, conferences and user group events. Collaborating with leading providers Fast Track and invivodata, as well as CDISC, Medidata delivered webinars and demonstrations on leveraging industry standards to share data across systems, including protocol authoring and ePRO. Medidata also partnered with United BioSource Corporation and Tessella to deliver a six-part webinar series to educate sponsors and service providers on the complexities of planning and executing an adaptive clinical trial. In addition, Medidata executives chaired, presented and led expert panel discussions at key conferences this year, including the DIA Annual Meeting, Clinical Trials Congress, CDISC European Interchange, and DIA Japan.

Expanding the Team
To keep up with its growing global customer base and product research and development, Medidata increased its total number of worldwide resources by 44 percent in 2007. Significant additions to the company's executive team included Bruce Dalziel, chief financial officer; Barton Cobert, M.D., vice president of global regulatory initiatives and pharmacovigilance; Frances Nolan, vice president of global quality assurance; Tony Hewer, Ph.D., senior director of global quality assurance for EMEA (Europe, the Middle East and Africa); Michael Otner, general counsel; and Glenn Watt, corporate security and privacy officer and vice president of global information security and privacy.
