Summary:
The FDA has approved Roche’s VENTANA MET (SP44) RxDx Assay, the first companion diagnostic to identify MET protein expression in lung cancer patients eligible for AbbVie’s targeted therapy EMRELIS.

Takeaways:

  1. The test enables more personalized treatment for advanced NSCLC patients by identifying MET protein overexpression.
  2. The FDA’s accelerated approval was based on promising results from the Phase 2 LUMINOSITY study, showing a 35% response rate.
  3. Lung cancer remains the leading cause of cancer deaths globally, with MET protein testing offering a new option for patients lacking EGFR mutations.

‭Roche has announced that the U.S. Food‬ and Drug Administration (FDA) has approved the VENTANA MET (SP44) RxDx Assay, the first‬ companion diagnostic approved to aid in determining MET (also known as c-Met) protein‬ expression in NSCLC patients. These patients may now be eligible for treatment with AbbVie’s‬ c-Met-targeted therapy EMRELIS (telisotuzumab vedotin-tllv).‬‭ 2,3

‭“Understanding the molecular drivers in patients with non-small cell lung cancer is critical for‬ therapy selection,” says Matt Sause, CEO of Roche Diagnostics. “By identifying MET protein‬ expression at the appropriate stage in the patient journey, we can help provide timely, tailored‬ treatment options that may improve patient outcomes and offer hope to those facing this‬ challenging disease.”

‭Despite advances in treatment, lung cancer remains the leading cause of cancer-related deaths in‬ both men and women throughout the world.‬‭ 4‬

‭Lung cancer‬‭ is often diagnosed at an advanced‬ stage when treatment options are limited;‬‭ 5‬ median‬‭ survival is less than one year.‬‭2‬ ‭Approximately 85% of lung cancers are classified as NSCLC.‬‭ 6‬ Among advanced NSCLC patients with a normal (wild-type) epidermal growth factor receptor‬ (EGFR) gene, around a quarter exhibit high levels of MET protein,‬‭ 7‬ making MET protein expression‬ an important factor in determining treatment options for patients with this type of cancer .‬

‭Accelerated Approval

The FDA accelerated approval is supported by data from the Phase 2 LUMINOSITY study, an‬ ongoing study designed to characterize the efficacy and safety of EMRELIS in c-Met‬ overexpressing advanced NSCLC populations. Findings from the study showed patients with c-Met‬ protein high expression who received EMRELIS demonstrated 35% overall response rate (ORR)‬ and duration of response (DoR) with a median of 7.2 months.‬‭ 8

‭ The launch of the first immunohistochemistry (IHC) MET companion test exemplifies Roche’s‬ commitment in this area, and represents an important addition to the company’s market-leading‬ portfolio of immunohistochemistry (IHC) and in situ hybridization (ISH) companion diagnostics.‬ These diagnostics are designed to provide critical insights that enable more informed clinical‬ decisions, advancing personalized healthcare and improving patients’ lives.‬
