cell-free DNA

Investigators will compare results using Biocept's platform in cerebrospinal fluid to current standard methods for diagnosing leptomeningeal metastases.

University of Cambridge researchers found that the portion of tumor DNA in patients' blood could predict treatment response and time to disease progression.

The results confirmed that circulating mutations can be reliably detected and changed during treatment, and showed that they could be a valuable prognostic biomarker.

Natera will design a personalized liquid biopsy assay for each patient and will test its ability to monitor disease progression and treatment response. 

The company is planning to work with up to 40 sites, with an initial goal of sequencing circulating cell-free DNA from 10,000 people.

The goal of the Texas team is to identify methylation signatures that can help with prognosis and be used to develop noninvasive tests to monitor disease progression.

Clinical MDx firm OmniSeq has been an early-access user of the research-use-only assay and is working on validating it to predict checkpoint inhibitor response.

Horizon will supply cell-free DNA-based molecular reference standards for inclusion in CareDx’s cfDNA testing workflows for the monitoring of transplanted organ rejection.

The company is working with the University of Florida Health Cancer Center to validate its RadTox QuantiDNA test as a monitor of cfDNA in patient plasma.

The South San Francisco, California-based company was founded by Dennis Lo to use noninvasive methods for early detection of cancer and other diseases.
