Japan’s Keio University Chooses Medidata Rave
Tokyo-based Academic Research Organization Selects Medidata Rave as
Part of National Improvement in Clinical Trial Infrastructure

NEW YORK, N.Y. & TOKYO – April 25, 2011 – Medidata Solutions (NASDAQ: MDSO), a leading global provider of SaaS-based clinical development solutions, today announced that Keio Center for Clinical Research (CCR), one of Japan’s two centers of excellence promoting global clinical research, has chosen to standardize on Medidata Rave® as its electronic data capture (EDC) and clinical data management (CDM) solution.

Keio CCR was founded in 2006 as an academic research organization within Keio University School of Medicine under the auspices of the Ministry of Health, Labor and Welfare (MHLW) to assume a leading role in the national improvement of clinical trial infrastructure. Designated by the MHLW in 2009 as one of only two centers of excellence to promote global clinical research, Keio CCR plans and supports investigator-initiated, non-NDA clinical trials and observational clinical research, as well as industry-sponsored translational research, registration trials and post-marketing studies.

“Medidata Rave will be key to supporting our strategy of facilitating high-quality clinical research while looking to deliver optimum treatments and improve patient welfare,” said Keio University Center for Clinical Research Professor Yuji Sato M.D., Ph.D.

Keio CCR is upgrading its EDC solution in order to continue to expand, accelerate and improve the quality of its multinational and multicenter clinical studies. Medidata Rave’s scalable, investigator-friendly system, which was originally developed for academic clinical trials, will enable Keio CCR to continue to grow its clinical research capabilities.

Academic research centers, government agencies and other non-profit organizations in all geographies are increasingly selecting Medidata Rave for their clinical trial needs based on Rave’s advanced technology and configurability for any phase, size or therapeutic area trial, as well as Medidata’s customer-centric approach and knowledge transfer program.

“Keio Center for Clinical Research is one of the most well-respected and innovative academic institutions in Japan, and we are excited to help them expand their global clinical program,” said Tarek Sherif, CEO, Medidata Solutions. “Keio’s selection of Medidata Rave is further proof of our ability to understand and deliver solutions that overcome the specific challenges faced by academic research institutions around the world.”
