Genomic Health Announces Acceleration of Prostate Cancer Clinical Development Program

Updates Progress on Oncotype DX Colon Cancer Test

REDWOOD CITY, Calif., Jan. 10, 2011 /PRNewswire/ -- Genomic Health, Inc. (Nasdaq: GHDX) today announced it will accelerate its prostate cancer clinical development program with the goal of launching a test globally in 2013, previously planned for launch in 2014, in light of positive top-line results of a large gene identification study which were presented in December at the Society for Urologic Oncology (SUO) annual meeting.  Genomic Health and its research partners from Cleveland Clinic plan to present complete data at the ASCO Genitourinary Cancer Symposium and the United States & Canadian Academy of Pathology (USCAP) annual meeting in February 2011.

Developing a test that can address a critical dilemma in today's standard of care in prostate cancer will require well-designed clinical studies with reproducible evidence and the ability to work with very small amounts of biopsy tissue.  As with Genomic Health's development of the Oncotype DX® breast and colon cancer tests, the company expects to conduct multiple clinical studies to establish the clinical utility of its prostate cancer test.

The company also announced that it secured reimbursement for its Oncotype DX colon cancer test from Clalit, the largest insurer in Israel covering 65 percent of the population, and expects to report results from a second recurrence study in stage II colon cancer in 2011.

Kim Popovits, Genomic Health's Chief Executive Officer, will provide a business update today at 3:30 p.m. at the 29th Annual JP Morgan Healthcare Conference highlighting the company's priorities for 2011.  Ms. Popovits will be joined at the conference by the management team of Genomic Health, which includes Dean Schorno, who has been named as the company's Chief Financial Officer.  Mr. Schorno was previously the Senior Vice President of Finance and has served with the company for nine years in various capacities, including managing the launch and operations of Genomic Health's clinical laboratory as Vice President, Operations.  This appointment enables Brad Cole, Chief Operating Officer, who previously held both the COO and CFO roles, to expand his focus on the company's growing global business.
