First-Ever FDA Approval of Liquid Biopsy for Detecting Lung Cancer
The New York Times reports that Roche, a Swiss biotech company, recently received the first-ever FDA approval for a “liquid biopsy” test for diagnosing non-small cell lung cancer (NSCLC). The Times reports that while the test may not be perfect, it was able to produce results that generally agree with those of an invasive tumor biopsy. NSCLC is recognized as the most common form of lung cancer, accounting for approximately 85% of all detected lung cancers. Therefore, the market for Roche’s test is likely robust.
Approvals of liquid biopsy tests make it possible to deliver highly individualized health care for patients. Liquid biopsies also have the potential to allow physicians to identify patients whose tumors have specific mutations in the least invasive way possible.
The FDA specifically identified that Roche’s liquid biopsy can now be used as a blood-based companion diagnostic for Genetech’s cancer drug Tarceva (erlotinib), which was approved in 2013 as a first-line treatment for patients with metastatic NSCLC whose tumors have EGFR exon 19 deletions or L858R substitution mutations, the same genetic mutations identified by Roche’s new test.
Medical professionals appear accepting of the new technology and excited regarding the role it could fill in patient treatment – Dr. Benjamin Levy, MD, Director of Thoracic Medical Oncology at Mount Sinai Health Systems and Hospital said:
The advent of liquid diagnostic platforms in non-small cell lung cancer is truly a game changer in the diagnostic workup of advanced stage patients. The ability to both isolate and genetically interrogate tumor DNA from a simple minimally invasive test that can subsequently inform treatment decisions is a win for both physician and patient.
