TwinStrand's duplex sequencing correction technology can detect ultra-low frequency DNA mutations that are otherwise often obscured by technical noise.
The new consortium is aiming to make comprehensive genomic profiling accessible to advanced cancer patients in the US, to help inform their treatment decisions.
The test will use a blood-based biopsy to detect patients with BRCA1, BRCA2, and/or ATM alterations in metastatic castration-resistant prostate cancer.
Though Guardant and Foundation have pioneered a path through the FDA for liquid biopsy tests, label differences highlight complex choices for oncologists.
FoundationOne Liquid CDx can now be used as a companion diagnostic for therapies to treat advanced ovarian, breast, and non-small cell lung cancer.
The test analyzes substitutions, insertion and deletion alterations, and copy number alterations in 324 genes, along with some genomic signatures in solid tumors.
The tests will be developed to identify NSCLC patients with ALK fusions and EGFR Exon20 insertion mutations who respond to mobocertinib or brigatinib.
The move raises questions about what precisely is an LDT outside of FDA jurisdiction and heightens concerns that poorly validated tests will enter the market and endanger public health.
The agency approved the test for use across solid tumors and with multiple companion diagnostic indications including one for prostate cancer and three for lung cancer.
OneOncology, a network comprising community oncology practices across the US, will bring its patient data to the research-focused partnership.
