KRAS Biomarkers

News and reporting on KRAS biomarkers.

Biocartis' Idylla called some colorectal cancer samples negative that Sysmex Inostics's OncoBEAM called positive, but the clinical implications may be complex.

In the 44-patient study, onvansertib will be studied in combination with Avastin and FOLFIRI in the second-line metastatic colorectal cancer setting.

Keytruda and Ibrance demonstrate activity in molecularly defined populations, while a new cohort will explore Gilotrif in tumors with NRG1 fusions.

Researchers used a genome-scale CRISPRi platform to identify genetic interactions with an inhibitor for a mutant form of KRAS in models of lung and pancreatic cancer.

News on molecular markers used to guide cancer treatment, assess prognosis, or detect relapse.

The NGS assay is designed to help physicians to identify non-small cell lung cancer patients who may benefit from eight targeted therapies.

The assay can identify KRAS, NRAS, PIK3CA, BRAF, and EGFR gene mutations, as well as 19 gene rearrangements of the ALK, ROS1, RET, NTRK1, and MET genes from FFPE.

The test is designed to detect cancer-driver gene variants associated with certain targeted solid tumor therapies, and is validated as a companion diagnostic.

The group plans to use the assay for translational studies on metastasis and drug resistance initially and to develop a clinical version later on.

The recent study highlights strengths and weaknesses of numerous platforms and may help end users choose the best assay for their circumstances.
