EXACT Sciences Corporation (EXAS) Reports on Laboratory Corporation of America Holdings (LH)'s Plans to Launch a New Laboratory-developed Stool-based DNA Screening Test for Colorectal Cancer in 2008; LabCorp Stopped Offering PreGen-Plus

6/5/2008 7:10:44 AM

MARLBOROUGH, Mass.--(BUSINESS WIRE)--EXACT Sciences Corporation (NASDAQ: EXAS - News) today announced that Laboratory Corporation of America® Holdings (LabCorp®) informed EXACT that it plans to launch a single-marker, laboratory-developed, stool-based DNA test for colorectal cancer screening in 2008. In connection with the planned transition to the new test, LabCorp has stopped offering PreGen-Plus™, the version of the stool-based DNA technology that has been the subject of Food and Drug Administration (FDA) inquiry over the past several years. Instead, LabCorp plans to move to a new stool-based DNA test, which is different from EXACT’s Version 2 technology and is based solely on the Vimentin gene, a methylated DNA marker that in published studies was shown to be associated with colorectal cancer. EXACT has exclusive worldwide license rights to the Vimentin gene from Case Western Reserve University for stool-based colorectal cancer detection. LabCorp has rights to access the Vimentin gene under the Company’s exclusive license agreement with LabCorp, and EXACT will be entitled to the same royalty and milestone structure on sales of the new test.

“Our understanding from LabCorp is that they plan to launch their new single-marker test without the use of Effipure or other elements of PreGen-Plus that had been the focus of prior FDA communications,” said Jeffrey R. Luber, President and Chief Executive Officer of EXACT Sciences. “Independent of LabCorp’s commercial launch of this test, EXACT continues to advance its Version 2 technology toward FDA clearance or approval. We recently met with the FDA and look forward to continuing our discussions with the goal of finalizing the protocol for our validation studies for Version 2 as soon as possible.”

About Vimentin

The relationship of the hypermethylation of the Vimentin gene to colon cancer was discovered by Sanford Markowitz, M.D., Ph.D. and colleagues at Case Western Reserve University, Department of Medicine and has been the subject of scientific publications. EXACT maintains an exclusive worldwide license to Vimentin from Case Western Reserve University, with the right to sublicense it to others.

About Colorectal Cancer

Colorectal cancer is the most deadly cancer among non-smoking men and women in the United States, and the second most deadly cancer overall. The American Cancer Society estimates that nearly 150,000 cases will be diagnosed and 50,000 deaths are anticipated in 2008 due to this disease. Despite the availability of colorectal cancer screening and diagnostic tests for more than 20 years, the rate of early detection of colorectal cancer remains low, and deaths remain high. It is estimated that roughly one-third of colorectal cancer-related deaths could be saved if more people underwent regular screening. Early diagnosis results in a greater than 90 percent, five-year survival rate.
