Berlin, March 8, 2010 - Epigenomics AG (ISIN: DE000A0BVT96), a cancer
molecular diagnostics company, reports updated top-line PRESEPT Study
data showing that the Septin9 biomarker in this research study 
detected colorectal cancer cases with a sensitivity of approximately 
63% based on 32 colorectal cancer (CRC) cases correctly identified 
out of 51 cancer cases with valid measurements of Septin9 in blood 
plasma samples. With this performance the PRESEPT Study has met its 
objective of detecting the majority of prevalent and incident cancers
in a screening cohort, a requirement for noninvasive screening tests 
set forth in current joint guidelines by the American Cancer Society,
the US Multi-Society Task Force on Colorectal Cancer, and the 
American College of Radiology (1). With a specificity of around 89% 
the Septin9 testing result meets the targeted specificity range of 
85% to 90%, which based on an initial health economic analysis, 
should support public and private payer coverage and reimbursement.
As originally foreseen in the study protocol, the study results were 
updated upon testing of samples determined to be invalid along with 
testing of a small number of additional cancer cases identified after
the previous testing was initiated. Furthermore, investigative 
actions were implemented after a preliminary data analysis in January
15, 2010 had indicated that one of the three laboratories performing 
the Septin9 testing had reported a cancer detection rate that 
deviated from findings in the other PRESEPT Study testing 
laboratories and all previous studies. An investigation into these 
results led to retesting potentially affected samples by the other 
two labs. In addition a remainder of material leftover from 
processing of the samples measured in the study was also tested for 
Septin9 at each of the three independent laboratories and included 
into the analysis. The combined results from all of the above testing
activities contributed to the improved test performance reported.
Epigenomics can now report that the additional testing directed by 
the PRESEPT Clinical Study Steering Committee (CSSC) has been 
completed, and the Committee has reported to Epigenomics that the 
primary objective of the study of identifying the majority of 
colorectal cancer cases has been successfully met. Although 
histopathological review and further detailed statistical analysis 
remain to be completed, the CSSC concludes the results are not 
inconsistent with case-control studies previously reported (2-4) and 
that the data indicate that Septin9 testing may be a useful tool to 
detect the presence of occult colorectal cancer in a standard plasma 
specimen obtained from average risk individuals eligible for 
colorectal cancer screening. Later this year the CSSC will submit the
PRESEPT Study results for presentation at a major medical meeting and
peer-reviewed publication in a major scientific journal.
A simple blood test for colorectal cancer, which can be made 
available to the large group of patients who are eligible for 
colorectal cancer screening, but are unwilling or unable to use other
available methods, has the potential to address the lack of 
compliance with today's screening approaches (5). Based on the 
Septin9 performance data and the prevalence of CRC observed in the 
PRESEPT Study cohort, a primary care physician informing a patient of
a Septin9 test result that is negative for colorectal cancer, can do 
so with the certainty of it being correct 99.7% of the time (Negative
Predictive Value).
PRESEPT is a prospective multi-center clinical research study started
in 2008 to evaluate the performance characteristics and health 
economic benefit of colorectal cancer screening using Epigenomics' 
Septin9 blood test in a screening population. The PRESEPT Study is 
one of the largest commercially sponsored colorectal cancer screening
clinical studies ever conducted. Between June 2008 and December 2009,
in total 7,941 screening eligible average risk subjects were enrolled
into the PRESEPT Study at 32 clinical sites in the U.S. and Germany. 
This study population contained 53 cases of previously unsuspected 
colorectal cancer that were identified by screening colonoscopies 
performed on all study participants. Over two-thirds of the 53 
colorectal cancer cases identified in the cohort were early stage 
disease (Stages I and II) with a large proportion of the stage I 
colorectal cancer cases being very early stage disease (so-called 
pT1) as determined by pathology.
