circulating tumor DNA

Presentations at this month's ASCO meeting demonstrated how efforts are advancing to determine when and how longitudinal ctDNA testing will be useful for oncologists.

The firm said it can detect circulating tumor DNA with a mutational allele frequency of 0.001 percent, enabled by digital PCR and the firm's proprietary chemistry. 

The firm is in the midst of a clinical trial called NOVA to compare its circulating-tumor DNA-based Colvera test to DiaSorin's carcinoembryonic antigen assay.

The company reported that its genome-wide methylation approach could detect 77 percent of stage II cancers in its ongoing case-control CCGA study.

Thrive Earlier Detection is banking on targeted detection of frequent cancer mutations, coupled with protein markers, while competitors turn to genome-wide approaches.

The company is commercializing a method developed by researchers at Johns Hopkins that detects cancer with high specificity from a blood sample.

Investigators concluded that the spiked samples from SeraCare were a robust tool for inter-lab comparisons and discussed some areas of discordance seen in the study.

The firm plans to use the funds raised to support business activities, as it moves forward in the development of cancer early detection tests.

 

The company said adopters are ordering tests in areas of great interest, like CTC and blood biomarker monitoring, despite a lack of reimbursement.

The company estimated that the offering could raise between $327.2 and $376.3 million, which it would use for various corporate purposes.
