ALK Biomarkers

News and reporting on ALK biomarkers.

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 companion diagnostic for Pfizer's Xalkori identifies 14 ROS1 gene fusions by analyzing tumor messenger RNA from human tumor tissue or body fluids.

The agency is excluding certain advanced diagnostic lab tests and molecular pathology tests from a billing regulation that created administrative headaches for many labs.

The researchers combined different proteomic methods to explore the activity of the ALK inhibitor ceritinib and identify potential combination therapies.

Researchers identified unique ALK rearrangements in patients that lack previously known indicators of mesothelioma.

Patients are organizing themselves in groups based on the molecular features driving their tumors to better advocate for themselves, raise money, and influence research.

Investigators will use Biocept's liquid biopsy tests to detect ALK rearrangements both at baseline and to monitor treatment response and resistance mechanisms.

The changes include recommendations for first line immunotherapy in patients with high PD-L1 expression, and clarification on use of targeted therapies.

In head-to-head studies, a next-generation EGFR inhibitor and an ALK inhibitor beat their older counterparts in staving of cancer progression.  

The IHC test was used in clinical studies that led to Zykadia's approval last week as a first-line option for metastatic NSCLC patients with ALK rearrangements.
