The U.S. FDA revealed good news for Guardant Health Inc. Specifically, the agency has given a thumbs up for Guardant360 CDx for tumor mutation profiling, also known as comprehensive genomic profiling (CGP), in patients with any solid malignant neoplasm. The Redwood City, Calif.-based company noted that this marked the first approval to combine next-generation sequencing (NGS) and liquid biopsy in one diagnostic test to guide treatment decisions. The assay previously was granted a breakthrough device designation.
