Rules-Based Medicine Reaches a Significant Milestone in Companion Diagnostic Program With Roche

Milestone Demonstrates Effectiveness of RBM's Strategic Biomarker Services

AUSTIN, Texas, May 25, 2011 /PRNewswire/ -- Rules-Based Medicine (RBM), a global leader in biomarker testing services, and its subsidiary, Psynova Neurotech, has achieved a significant milestone in a companion diagnostic development program with Roche. Using samples from a Roche clinical trial, the RBM DiscoveryMAP® platform, and Psynova's biomarker database and expertise, a biomarker pattern was identified that has utility in prognosis of disease progression and/or predicting or monitoring the efficacy for a compound in the Roche CNS pipeline. Roche has exercised its option to continue commercial development based on these results, which could result in additional future milestone and royalty payments to RBM/Psynova.

"Achieving this milestone is an example of how pharmaceutical and biotechnology companies can leverage RBM's testing services, databases, and expertise to make real progress," said Craig Benson, President and CEO of RBM. "We appreciate the opportunity to work with a company of Roche's stature and experience to develop a product that both meets Roche's needs and can potentially improve patient outcomes. RBM values this relationship with a company that is leading the way and shares our vision for personalized healthcare"

This project highlights Rules-Based Medicine's Strategic Biomarker Services. RBM consults with our partners to design the best clinical trial, using our comprehensive menu of quantitative immunoassays and decades of expertise in sample type selection, experimental design, and data analysis.
