EGFR Biomarkers

News and reporting on EGFR biomarkers.

Labs in China can now use the Cobas EGFR Mutation Test v2 with either tissue or plasma samples as a CDx for three Roche oncology drugs in NSCLC patients.

The study plans to recruit close to 300 patients with advanced non-small cell lung cancer, with half being treated based on liquid biopsy results.

In the JAMA study, researchers confirmed the previously known clinical and genomic features of NSCLC patients in their large clinico-genomics database.

Based on the findings, MD Anderson is already using HER2 status to recommend patients for clinical trials instead of EGFR drugs and authors recommend others follow suit.

The researchers believe using cerebral spinal fluid will enable them to identify brain tumors with a higher sensitivity than with blood samples.

Qiagen's test detects the most frequently occurring somatic mutations in EGFR in less than four hours using real-time PCR on the Rotor-Gene Q platform.

The firms will begin a prospective lung cancer study using Biocartis' Idylla EGFR mutation test in European countries, including Belgium, France, Germany, and Italy.

The partners will use a $5M NCI grant to add seven biomarkers to an EGFR electrochemical assay for non-small-cell lung-carcinoma.

Researchers separately found that the assay had high concordance with other techniques in cancers including colorectal and endometrial carcinomas.

The assay can identify KRAS, NRAS, PIK3CA, BRAF, and EGFR gene mutations, as well as 19 gene rearrangements of the ALK, ROS1, RET, NTRK1, and MET genes from FFPE.
