Foundation Medicine Companion Diagnostic Approved
FDA has approved a Foundation Medicine PMA for its FoundationOne CDx to be used as a companion diagnostic for the two approved indications for Genentech’s Rozlytrek (entrectinib). In 2019, FDA approved Rozlytrek for treating adult and adolescent patients whose cancers have the specific genetic defect NTRK (neurotrophic tyrosine receptor kinase) gene fusion and for whom there are no effective treatments. The drug also was approved for treating adults with non-small cell lung cancer (NSCLC) whose tumors are ROS1-positive (mutation of the ROS1 gene) and have spread to other parts of the body.
As a condition of approval, Foundation Medicine says it will conduct a post-approval study powered by the Flatiron Health-Foundation Medicine Clinico-Genomic Database (CGDB) to further demonstrate the diagnostic’s ability to identify NSCLC patients with ROS1 fusions who may respond to Rozlytrek (entrectinib). The company says CGDB is a de-identified, HIPAA-compliant database that links outcomes data from Flatiron’s network of oncology clinics and genomic data from Foundation Medicine’s CGP assays. It currently contains more than 100,000 linked genomic profiles.
