QIAGEN N.V. (NASDAQ: QGEN; Frankfurt Prime Standard: QIA) today announced that
Clarient - a GE Healthcare Company and leading provider of cancer laboratory
testing services in the United States - has adopted the use of the
therascreen^® KRAS RGQ PCR Kit (therascreen KRAS test) as a companion
diagnostic to guide the use of Erbitux^® (cetuximab) as a treatment in
patients with metastatic colorectal cancer. Clarient, with a customer base of
more than 2,000 pathologists, oncologists, clinical laboratories and
hospitals, selected QIAGEN's therascreen KRAS test and QIAGEN's Rotor-Gene Q
MDx instrument following the Food and Drug Administration (FDA) approval of
the test in July 2012. Clarient joins a rapidly growing number of laboratories
switching from laboratory-developed tests (LDTs) to the FDA-approved
therascreen KRAS test for diagnostic testing for late stage colorectal cancer.

"We are very pleased to partner with Clarient, a leading laboratory with a
strong reputation among pathologists, oncologists and hospitals, to offer the
therascreen KRAS test. Together, we will help bring our shared vision of the
value of personalized healthcare to reality and transform outcomes by
delivering personalized information to guide physicians and patients in the
treatment of late-stage colorectal cancer," said Dr. Helge Lubenow, Senior
Vice President, Molecular Diagnostics Business Area and member of the
Executive Committee of QIAGEN. "The future of Personalized Healthcare will be
shaped by standardized tests like the therascreen KRAS test, backed by
scientific rigor and regulatory review. Our growing portfolio of innovative
diagnostics and efficient automation platforms is making healthcare more
effective, saving money for payers and improving life for patients."

"We believe precision medicine is the new direction in diagnosing and treating
cancer and Clarient uses state-of-the-art diagnostic technologies like the
therascreen KRAS test to bring clarity and precision to physicians to assist
them in making better treatment decisions for their patients," said Carrie
Eglinton Manner, CEO, Clarient. "Clarient's comprehensive offering and fast
turnaround time coupled with our experience with the therascreen KRAS test
permits us to provide a higher level of performance. Also, the fact that it is
FDA approved provides Clarient with additional assurance of its quality and

The U.S. launch of the therascreen KRAS test system including the Rotor-Gene Q
MDx instrument, approved by the FDA in July 2012, is progressing well. To
drive adoption, QIAGEN supports partners like Clarient with co-marketing
programs, reimbursement service, on-site validation and communication with
pathologists and oncologists. For an updated list of U.S. laboratories now

Approximately 110,000 metastatic colorectal cancer patients each year in the
U.S. could benefit from KRAS testing, according to QIAGEN estimates. In
patients for whom standalone surgery and chemotherapy are insufficient,
treatment with an epidermal growth factor receptor (EGFR) inhibitor such as
Erbitux has been shown to improve overall survival. However, determining the
presence or absence of KRAS mutations in tumors affects outcomes.
Approximately 60% of patients, whose tumors have mutation-negative (wild-type)
KRAS genes, may benefit from anti-EGFR therapy. Approximately 40%, whose
tumors have KRAS mutations, may not benefit.

QIAGEN's FDA-approved therascreen KRAS test offers a fast, consistent and
reliable process to determine optimal treatment for colorectal cancer patients
who are candidates for EGFR-inhibitor therapy. QIAGEN's therascreen KRAS test
has been shown to have a high sensitivity (low limit of detection) for KRAS
mutations, a critical factor in ensuring high-quality data for treatment

The U.S. healthcare system could save more than $600 million a year by
determining KRAS status in colorectal cancer patients and avoiding unnecessary
use of medicines, studies show.

QIAGEN is actively expanding its global portfolio of Personalized Healthcare
technologies and intends to submit several companion diagnostics for U.S.
regulatory approval. Earlier this month the Company announced submission of
its therascreen^® EGFR RGQ PCR Kit to the FDA as a proposed companion
diagnostic to guide treatment with afatinib, a new investigational oncology
compound developed by Boehringer Ingelheim. More than 15 projects are under
way to co-develop and market companion diagnostics with other leading
pharmaceutical and biotech companies such as Amgen, AstraZeneca, Bayer and

The U.S. rollout of the therascreen KRAS test builds on success in Europe,
where QIAGEN offers 10 CE-marked assays based on real-time PCR technology or
on Pyrosequencing. QIAGEN currently markets therascreen assays in Europe for
biomarkers including KRAS, EGFR, NRAS, BRAF, PI3K, JAK2, MGMT and UGT1A1. In
Japan, regulators approved the therascreen KRAS and EGFR kits in 2011,
solidifying QIAGEN's leadership in that market. QIAGEN also offers
technologies for research use in the development of new medicines and
companion diagnostics.
