World's first complete Sample to Insight NGS solution proves equal or better compared with other sequencing workflows and alternative technologies

Austin, Texas, and Hilden, Germany, November 4, 2015 - QIAGEN N.V. (NASDAQ: QGEN; Frankfurt Prime Standard: QIA) today announced that an evaluation has affirmed the performance of the Company's GeneReader NGS System in detecting gene variants known to be clinically relevant in colorectal cancer. Results of the analysis, performed by the Broad Institute of MIT and Harvard, a leading biomedical research and sequencing center, will be presented at the Association for Molecular Pathology (AMP) 2015 Annual Meeting on November 4, 2015, in Austin, Texas.

This inquiry is the first assessment of the GeneReader NGS System's performance in delivering insights on relevant cancer mutations in a laboratory setting. Data from the GeneReader NGS System* compared favorably with QIAGEN's therascreen RAS mutation tests based on real-time qualitative polymerase chain reaction (PCR) and pyrosequencing, as well as with a next-generation sequencing (NGS) workflow using a competitor's sequencer. All of the methods were used to test the same 43 tumor samples of confirmed metastatic colorectal cancer from FFPE as sample material.

'Next-generation sequencing can deliver valuable insights for clinical research and diagnostic labs, but users urgently need a simpler, more efficient and cost-effective workflow for NGS technology to enter the mainstream. QIAGEN created the GeneReader NGS System as the first complete Sample to Insight NGS solution designed for any lab to deliver actionable results - and this analysis supports that capability,' said Peer M. Schatz, Chief Executive Officer of QIAGEN. 'Integrated with the most comprehensive, up-to-date knowledge base through our QIAGEN Clinical Insight software, the GeneReader NGS System is a turnkey solution that is affordable, easy to run - and delivers clinically relevant insights.'

In the analysis, data from the GeneReader NGS System were found to be 100% concordant with results of QIAGEN's FDA approved therascreen KRAS RGQ PCR assay and the company's CE-labelled therascreen RAS Extension Pyro Assay. In comparison to these technologies, the GeneReader workflow identified additional aberrations, enabling a more comprehensive investigation of clinically actionable variants (e.g. in the BRAF-gene). Compared to data of the other NGS workflow, which involved an Illumina MiSeq Sequencer, the GeneReader showed 100% positive agreement. Because the data generated by the QIAGEN GeneReader NGS System had fewer FFPE artifacts, it rendered a more accurate reflection of genuine somatic mutations in the samples. For the analysis, the Broad Institute used the Actionable Insights Tumor Panel, the first member of the family of GeneRead QIAact panels powered by QCI®, which was designed with the QIAGEN Knowledge Base to focus only on genes and variants with direct clinical relevance. The panel will be commercially available in the coming weeks.

The QIAGEN Clinical Insight Interpret tool builds on the QIAGEN Knowledge Base and streamlines the creation of a customizable report for each sample based on the test results, with direct links to source information on therapeutic agents, practice guidelines or clinical trials. The comprehensive test report with all the relevant information delivers actionable insights with the highest confidence and efficiency. QIAGEN's complete NGS solution also includes a software package linking the workflow to a lab's Laboratory Information System (LIS), enabling tracking of samples and tests, triangulation of NGS data with other results, and a holistic view of each individual case.

'We were pleased with results of the analysis, and optimistic about the System's potential to deliver accurate and actionable data with high efficiency and low adoption hurdle', said Dr. Scott Steelman, Associate Director of Technology Labs for the Broad Institute, who led the institute's analysis of the new NGS workflow.

Commercialization of the QIAGEN GeneReader NGS System will be initiated at the AMP 2015 Annual Meeting, in Austin, Texas, where data from the Broad Institute analysis will be presented in a Corporate Workshop.

Time: November 4, 3:00 - 3:50pm

Speaker: Dr. Scott Steelman, The Broad Institute of MIT and Harvard

Location: Grand Ballroom E, Austin Convention Center, Austin, Texas.
