FDA Approves Roche’s Cobas EGFR Mutation Test in Lung Cancer Patients

Share

FDA has approved Roche’s cobas EGFR Mutation Test v2, a companion diagnostic for the cancer drug Tarceva (erlotinib) that is the first blood-based genetic test detect epidermal growth factor receptor (EGFR) gene mutations in non-small cell lung cancer patients, according to an agency release. “With the cobas EGFR Mutation Test v2,” the release says, “the presence of specific NSCLC mutations [exon 19 deletion or exon 21 (L858R) substitution mutations] detected in patients’ blood samples aids in selecting those who may benefit from treatment with Tarceva. However, if such mutations are not detected in the blood, then a tumor biopsy should be performed to determine if the NSCLC mutations are present.”

 

FDA approved Tarceva in 2004 to treat patients with locally advanced or metastatic NSCLC after failure of at least one prior chemotherapy regimen, and in 2013 it was given expanded approval as a first-line treatment for patients with metastatic non-small cell lung cancer whose tumors having EGFR exon 19 deletions or L858R substitution mutations as detected by an FDA-approved test.
