Roche Companion Diagnostic for AbbVie’s Emrelis OK’d
FDA has approved Roche’s Ventana MET (SP44) RxDx Assay, a companion diagnostic to aid in determining MET (also known as c-Met) protein expression in lung cancer patients to determine eligibility for AbbVie’s just-approved Emrelis (see earlier story).
The device detects the MET protein and is scored by pathologists based on the percentage of tumor cells stained and the intensity of the staining, Roche says. Approval was based on data from AbbVie’s Phase 2 LUMINOSITY clinical study, in which the test was used as the enrollment assay. MET protein overexpression is defined as greater than 50% tumor cells demonstrating strong membrane and/or cytoplasmic staining, it says.
