The firm saw total revenues of $859,526 for the three months ended Dec. 31, 2018 compared to $995,226 in the same period of 2017.
Funds raised will help accelerate commercialization of the firm's InVisionFirst-Lung liquid biopsy test and support development of the firm's platform for new indications
Under the agreement, Bellwether researchers will join the team advancing Guardant's LUNAR early cancer detection and monitoring assays.
The firms plan to use Natera's cell-free DNA liquid biopsy assay to monitor patients' response to Amal's cancer vaccine in combination with immunotherapy.
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."
The ctDNA test will be covered for all US fee-for-service Medicare patients with advanced (Stage IIIB/IV) NSCLC who meet specific clinical criteria.
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 company received Chinese regulatory approval for a lung cancer assay last year and plans to seek approval for a liquid biopsy test this year.
