Compendia Bioscience and Althea Diagnostics Develop Breast Cancer Segregation Panel(TM) Assay as a Platform for Companion Diagnostic Development

Ann Arbor, Mich. (December 8, 2010) — Compendia Bioscience today announced a new strategic partnership with Althea Diagnostics and the immediate availability of the partnership’s first joint product and service offerings — the Breast Cancer Segregation Panel™ Assay and Analysis Service. The Breast Cancer Segregation Panel measures 96 genes that represent key molecular variability of breast cancer and have been derived from a proprietary meta-analysis of cancer genomic profiles from more than 5,000 clinical samples. The assay has been optimized by Althea Diagnostics to measure the genes using quantitative RT-PCR from formalin-fixed tissue (FFPE) samples to enable rapid translation to real-world clinical settings.

Compendia Bioscience will analyze the data generated by the assay and will perform correlation studies to end-points of interest — such as drug response. This will allow for development of multiple drug-specific companion diagnostics from a standardized platform.

The partnership leverages the unique expertise of each company. Compendia Bioscience is a recognized leader in the cancer genomics data collection, curation and analysis. Althea Diagnostics has a long pedigree in gene quantification from FFPE samples and is a leading provider of diagnostic development services for pharmaceutical companies. The companies have also announced that they plan to develop similar assays for other cancer disease types. The companies have begun development of a Colon Segregation Panel™ assay, which will be available in 2011.
