circulating tumor DNA

The company is employing Guardant360 in a Phase III trial assessing the efficacy of the drug both in a larger population and in women who test positive for ESR1 mutations.

The firm will use the proceeds to advance its liquid biopsy early cancer detection assay CancerSEEK in an FDA registrational trial.

The collaborators will use SensID's controls with Saga's digital PCR-based Sagasafe technology, which can detect and quantify circulating tumor DNA in cancer patients at ultra-low allelic frequencies.

The initiative will offer a liquid biopsy tool that only requires a blood draw for cancer treatment selection instead of a tissue biopsy. 

Analyzing both circulating tumor DNA and circulating tumor cells, investigators could classify patients into groups with significantly higher and lower recurrence risk.

Researchers concluded that there has been significant expansion of coverage for ctDNA assays over the past four years, but policies remain very heterogeneous and often limited.

The companies will work together to bring Guardant360 through regulatory approval and commercialize it as a CDx for Janssen's amivantamab.

Investigators reported that methylation profiling could distinguish brain cancer subtypes and could detect kidney cancer with striking sensitivity in early experiments.

In one study, the UK-based firm found that its RaDaR assay detected circulating tumor DNA in lung cancer patients up to a year before standard clinical progression occurred in most of the cases.
