Signatera MRD test – pro
On MAY 6, U.S. Food and Drug Administration (FDA) has granted “Breakthrough Device” designation for its Signatera test for use in the post-surgical detection and quantification of circulating tumor DNA (ctDNA) in the blood of patients previously diagnosed with certain types of cancer and in combination with certain drugs. On March 24, 2021 /PRNewswire/ Natera, Inc. (NASDAQ: NTRA), a pioneer and global leader in cell-free DNA testing, today announced that the US Food and Drug Administration (FDA) has granted two Breakthrough Device Designations (BDDs) covering new intended uses of the Signatera molecular residual disease (MRD) test. These new designations will support the development of Signatera through Phase III clinical trials as a companion diagnostic to two different cancer therapies.
No phase III trials had been performed and no guideline currently recommend this test.No phase III trials had been performed and no guideline currently recommend this test. Signatera claims that NCCN approved of this test; however, I only found the following in the NCCN guideline : ” ctDNA is not recommended for surveillance.”
