ERCC1 Analysis Guides Patient Treatment Decisions

WESTBOROUGH, Mass.–Genzyme Genetics, a business unit of Genzyme Corporation, announced strong sales of ERCC1 Analysis, the first test for selecting chemotherapy for Non-Small Cell Lung Cancer (NSCLC), a cancer that will affect an estimated 219,000 people in the United States in 2009. Genzyme Corporation launched this test on May 1, 2009 and has sold XX tests. In November of 2007, Genzyme Corporation obtained exclusive rights to this lung cancer test from Moffitt Cancer Center.

Several studies^1-6have shown that evaluating the expression levels of excision repair cross-complementation group 1 (ERCC1) may help physicians identify patients that may benefit from platinum-based chemotherapy - currently considered the standard of care in advanced NSCLC. Specifically, low expression levels of ERCC1 have been related to a better response and survival benefit from adjuvant cisplatin-based chemotherapy.

"We are very pleased that many medical oncologists have begun utilizing this lung cancer test to better identify chemotherapy for non small cell lung cancer patients," said Jarett Rieger, Director of the Office of Technology Management and Licensing at Moffitt. "This test is an example of personalized medicine emanating from Moffitt Cancer Center, and as a result of our licensing partnership with Genyzme this test can now benefit lung cancer patients."

According to a 5-year retrospective study (n= 389) published in the New England Journal of Medicine, overall survival was significantly longer for patients with ERCC1-negative tumors who had received adjuvant cisplatin chemotherapy when compared to the control group treated by surgery alone (56 months vs 42 months, respectively). Among patients with ERCC1-positive tumors, there was no significant difference in survival between the adjuvant chemotherapy group and the control group (50 months vs 55 months respectively).
