Caprion Pharmaceuticals Inc., a drug-discovery company applying proteomics and cell biology expertise, today announced a collaboration to develop and operate a highly scalable bioinformatics platform for proteomic disease modeling as part of Caprion's CellCarta drug discovery offering. Bioinformatics Platform to Deliver High-Performance Solution for Acceleration of Drug Discovery

Caprion Pharmaceuticals Inc., a drug-discovery company applying proteomics and cell biology expertise, today announced a collaboration to develop and operate a highly scalable bioinformatics platform for proteomic disease modeling as part of Caprion's CellCarta drug discovery offering. Technologies, hardware and software from Sun Microsystems and Oracle, and systems integration expertise from CGI will be combined with Caprion's cell biology and mass spectrometry techniques to analyze, map and store the protein differences between normal and diseased cells.

Caprion's CellCarta Solaris platform, will include servers, storage and infrastructure solutions from Sun and Oracle, which will enable Caprion to effectively study proteins within cells by creating comprehensive three-dimensional maps of protein location and orientation in their biological context. Caprion uses mass spectrometers to digitize cellular information in multiple states, identifying and modeling disease. A data warehouse will be designed and developed by Oracle Consulting.

Caprion hopes to accelerate the detection of disease-related proteins through the creation of a specialized data centre. This centre, expected to be operational in September, 2001, will process up to 100 terabytes of information per year and will represent one of the largest and fastest dedicated protein analysis server banks in the world.

With the completion of a rough draft of the human genetic code, researchers are now launching large-scale efforts to study proteins, a field known as proteomics. Proteins carry information within and between cells, and carry out most of life's basic processes. Proteomics is expected to lead to advances in treating HIV, cancer and other diseases.

"We're very excited about this platform, because it brings the best solutions from Sun and Oracle which will speed breakthroughs in identifying disease-related proteins," said Lloyd M. Segal, president and chief executive officer of Caprion Pharmaceuticals. "Sun and Oracle's significant contributions of software and information management capabilities are beyond that of any proteomics company, and allow us to apply key knowledge from other industries to meet our challenges. CGI's ability to integrate the entire program made our goals of data throughput possible in the limited time we have available."

Sun is expected to invest substantial software engineering resources, professional services, Enterprise-class servers, Sun StorEdge offerings, and the Solaris Operating Environment. Sun is a leader in the UNIX systems and open storage market with a comprehensive set of network storage offerings for the enterprise market.

"Sun's highly reliable, scalable and available systems are already helping Caprion speed up the massive computational processing required to analyze their biological data," said Scott McNealy, chairman and CEO, Sun Microsystems, Inc. "Sun is providing a core piece of the technology that is enabling this proteomics revolution. With the potential for analysis of over one million proteins in the human body, Sun and Caprion are harnessing today's computing power to help transform the future of medicine."

In addition to using the Oracle database as the software foundation for the project, Oracle Consulting will design and develop the Pipeline data warehouse.

"Oracle is the most widely distributed database platform in the biotechnology and pharmaceutical industries," said Bill Bergen, president of Oracle Corporation Canada Inc. "Its robust and scaleable products will provide Caprion with a superior platform to meet - and exceed - its goals and objectives in the critically important areas of genetic research, proteomics and drug development."

CGI will provide system integration, consultation, project management and development for this project. CGI will support and maintain the data centre operations for a period of five years.

"We are very pleased and excited about this critical undertaking. We look forward to the challenge of integrating seven major components that have to talk to each other, all within this very complex structure. The challenges of the architecture are due to Caprion's ability to create unprecedented digital resolution of cells," said Serge Godin, chairman, president and CEO of CGI.
