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. 

Quest, the largest private, independent medical laboratory in Singapore, will now be able to offer Lucence's menu of liquid biopsy tests to its patients.

The institutes will explore the use of Inivata's liquid biopsy platform to analyze ctDNA to measure minimal residual disease in NSCLC patients.

The firm said it would likely do a joint submission of its ctDNA assay to the FDA and CMS for approval and a national coverage determination.

Investigators and commercial firms presenting at the recent AACR meeting highlighted how heterogeneous both the technology and the application of liquid biopsy remains.

The ctDNA assay will be used to select patients for Phase 3 of Five Prime's registrational trial investigating bemarituzumab in gastric cancer patients.

The company has highlighted the study as evidence that its test would outperform Roche's FDA-approved liquid biopsy assay if implemented in the clinic.

It will use the funds to help expand the development and commercialization of its non-invasive genetic tests for early-stage cancer detection.

The company's test boasted strong sensitivity and specificity for a range of different alterations in clinical and contrived samples, particularly for low-allele frequencies.
