Subtitle: Differences in analytical instrument read-out requires verification and potential retesting of samples measured in laboratory with deviating results

Top-line data expected still in Q1 2010

No impact on commercial strategy expected

Press release, Berlin, Germany, and Seattle, WA, U.S.A., February 4, 2010 (euro adhoc) - Epigenomics AG (Frankfurt, Prime Standard: ECX), a cancer molecular diagnostics company, today reported the conclusions from the investigation into the results from one of the three laboratories that were used to test samples of the PRESEPT Study cohort.

The investigation had been initiated by the Clinical Study Steering Committee (CSSC) following the reporting of preliminary results of the PRESEPT Study on January 15, 2010. These preliminary findings indicated that in two of the three testing laboratories that performed Septin9 testing on blood plasma samples from the PRESEPT Study, subjects achieved cancer detection rates of 62.5% each and therefore were well within expectations. The third laboratory reported a cancer detection rate of 28% which deviated from the findings in the other testing laboratories and all previous eight case control studies on the biomarker that in total included more than 3,300 plasma samples from cancer patients and control subjects. (Refs 1-3)

The thorough audits of the testing laboratories revealed that the analytical instrument used in the laboratory with the divergent results was a recently released new version of the device that was unique to this study laboratory. In the other two laboratories, a different instrument version was used. The audit team observed that the instrument which generated the lower than expected cancer detection rate reported unusually high fluorescence signals in several runs which could have impacted the read-out of results. Those signals could originate from the sample containers used on that device and/or the device itself. This observation was not made in any of the two other laboratories nor any previous study by Epigenomics. The audits at all three testing laboratories, Epigenomics' internal processes as well as the biostatistics group at the University of Minnesota performed as part of the investigation did not identify significant deviations related to sample traceability, sample handling, or sample processing which could explain the observed results.

Epigenomics will verify the cause for the observed high fluorescent signals and generate data to demonstrate whether and how far this could be responsible for the results observed in the lower cancer detection rate. If necessary, the company will retest study subject samples that were potentially affected by this incident.

In addition to the further investigation into the lower cancer detection rate in the one laboratory and following the recommendations of the CSSC, a small number of additional cancer cases will be tested. These cancer cases were confirmed by pathology after shipping the last testing batches to the laboratories in December. The CSSC had stipulated the testing of these samples in the original study plan to include the results in the final data set to be submitted to a peer-reviewed scientific journal for publication. The company still expects that all further testing and retesting of samples can be completed within Q1 2010. The company plans to release the updated top-line results from the study including the additional and repeated testing results once they become available.

"We are fully on track in executing on the commercialization of our already launched colorectal cancer blood test, the Epi proColon product", commented Geert Nygaard, Chief Executive Officer of Epigenomics. "It is important to realize that the PRESEPT Study is an academic medicine study. Its results remain entirely independent of the regulatory pathway such as future FDA approvals and clearances of our Epi proColon product, Abbott's mS9 assay, or Quest's ColoVantage test in any current or future market."

About Epigenomics

Epigenomics is a molecular diagnostics company with a focus on the development of novel products for cancer. Using DNA methylation biomarkers, Epigenomics' tests on the market and in development aim at diagnosing cancer at an early stage before symptoms occur and thereby may reduce mortality from this dreaded disease.

Epigenomics' product portfolio contains the CE-marked IVD test Epi proColon®, the world's first regulatory cleared molecular diagnostic test for the detection of colorectal cancer in blood that is based on the biomarker Septin9, and further proprietary DNA methylation biomarkers and IVD products at various stages of development for colorectal, lung and prostate cancer. For development and global commercialization of IVD test products, Epigenomics pursues a dual business strategy in which direct commercialization of proprietary diagnostic test products is combined with non-exclusive licensing to diagnostic industry players with broad customer access. Strategic diagnostics industry partners include Abbott Molecular, Philips, Sysmex Corporation, Quest Diagnostics Incorporated, and ARUP Laboratories, Inc. for diagnostics test products and services, and QIAGEN N.V. for sample preparation solutions and research products. The company is headquartered in Berlin, Germany, and has a wholly owned subsidiary, Epigenomics Inc., in Seattle, WA, U.S.A.
