circulating tumor DNA

The company's ctDx lung cancer assay identifies a variety of different actionable mutations in the blood of non-small cell lung cancer patients.

Of the six kits, the team found that Qiagen and Norgen's spin column tools recovered the highest amount of DNA across a range of base pair lengths.

The project aims to use circulating tumor DNA to monitor drug response and resistance in metastatic melanoma patients in order to guide treatment decisions.

The partners aim to optimize DNA nanoball technology, accelerate the use of CTC technology, and work on a diagnostic tool for use at the point of care.

Researchers showed, retrospectively, that using a cutoff of 16 circulating DNA mutations they could identify patients who were more likely to respond to immunotherapy.

A Samsung University team found that mutation load measured with the Guardant360 liquid biopsy assay predicted response as well as tissue-based TMB.

The lab will make Lucence's non-invasive cancer tests available to patients in the region, but financial and other terms were not disclosed.

The company will work with researchers at UCSD's Moores Cancer Center on two studies of patients with breast, lung, and colon cancers.

The German drugmaker plans to advance the NSCLC treatment in parallel with tissue-based and liquid biopsy companion assays that can identify best responders.

The Belgian cancer center plans to evaluate Natera's ctDNA assay for evaluating response and detecting minimal residual disease in breast cancer patients.
