Using BGI's sequencing technology, the firms plan to commercialize Natera's Signatera test in China and to develop reproductive health tests in "select markets."
Data being presented at the upcoming AACR meeting show that Guardant's liquid biopsy test provided more accurate and rapid mutation detection than tissue genotyping.
The assay monitors mutations across a patient's genome and matches them to mutations found in a patient's resected tumor and in DNA in the bloodstream.
The firm's has expanded its ctDNA sequencing test to cover 17 genes, enough to provide a readout of microsatellite instability for guiding cancer immunotherapy use.
The firm's new RT-PCR assay identifies 20 gene fusion between NTRK1/2/3 and other genes, allowing clinicians to potentially detect rare forms of different cancers.
The firm is moving into a larger facility after its first full year of profitability and planning new hires to support its plans to bring liquid biopsy kits through the FDA.
Plans are in place for a Guardant360-based assay to predict response to AsztraZeneca's Tagrisso and for a blood-based TMB test using the larger GuardantOmni panel.
