Roche launches the cobas EGFR Mutation Test v2 for use with either plasma or tumour tissue samples
New test is the first to be validated for use of either sample type in a single test
Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced the commercial availability in countries that accept the CE mark1 of the cobas EGFR Mutation Test v2, the first oncology assay from Roche that utilises either plasma or tumour tissue as a sample. The test identifies 42 mutations in the epidermal growth factor receptor (EGFR) gene, the most of any In-vitro Diagnostic (IVD) on the market, and can also be used as an aid in selecting eligible patients with non-small cell lung cancer (NSCLC) for therapy with an EGFR tyrosine kinase inhibitor (TKI).
“As more targeted therapies become available, it is critical that we provide innovative molecular testing methods that make it easier for patients to get tested, regardless of the surgery risks or tumour tissue availability,” said Roland Diggelmann, COO, Roche Diagnostics. “By investing in liquid biopsy research and developing the cobas EGFR Mutation Test v2 for use with either plasma or tissue samples, Roche is helping to remove these common barriers from molecular testing.”
According to a recent survey of more than 550 oncologists, EGFR genetic testing is not being conducted in about 25 percent of patients with NSCLC2,3. Some of the reasons for not testing included lack of diagnostic material and cases where a patient was deemed unfit to undergo biopsy. With the cobas EGFR Mutation Test v2 being validated with both tissue and plasma sample types, patients who previously did not qualify for biopsy now have the opportunity to receive a result from a simple plasma test to guide the corresponding therapy.
The cobas EGFR Mutation Test v2 is available now in countries that accept the CE mark1. For more information, please visit www.cobas-egfrtestv2.com.
About the cobas EGFR Mutation Test v2
The cobas EGFR Mutation Test v2 is a real-time PCR test that identifies 42 mutations in exons 18-21, including L858R, exon 19 deletions, L861Q and the TKI-resistance mutation, T790M. It is designed to enable testing of either tissue or plasma specimens with one kit, and allows labs to mix-batch tissue and plasma on the same plate. Additionally, Roche has developed a cell-free DNA (cfDNA) sample preparation kit that is optimised for extracting the DNA from plasma.
When testing plasma with the cobas EGFR Mutation Test v2, a new feature called the Semi-Quantitative Index (SQI) is included in the report. This number is designed to reflect a trend in the amount of mutant cfDNA in the sample. When frequently testing for the EGFR mutation using the test, tracking the SQI value and identifying a trend may lead to understanding tumour progression.
The cobas EGFR Mutation Test v2 is designed to run on the cobas 4800 System, v2.1 or higher. The system can also be used for the detection of mutations in the KRAS and BRAF gene of tumour samples.
