Biocept will use its liquid biopsy assay to test cerebrospinal fluids of patients diagnosed with certain cancers and then compare results to standard methods.
The NGS assay is designed to help physicians to identify non-small cell lung cancer patients who may benefit from eight targeted therapies.
Researchers will first compare liquid with tissue-based tumor profiling before implementing it as a way to enroll patients into the targeted drug trials.
In a colon cancer model, researchers saw transcriptional changes and population expansions in some checkpoint receptor-negative tumor-infiltrating T cells.
The study authors cautioned that immunological signatures cannot be predicted from tumor mutational burden or microenvironment analysis of a single biopsy alone.
The firms will begin a prospective lung cancer study using Biocartis' Idylla EGFR mutation test in European countries, including Belgium, France, Germany, and Italy.
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 new approval will allow the use of Qiagen's Therascreen EGFR RGQ PCR Kit as a companion diagnostic for Pfizer's Vizimpro in NSCLC patients.
An Oregon Health Authority committee issued a draft guidance to not cover NGS testing for solid tumors, which advocacy groups say will limit access to Medicaid beneficiaries.
A phylogenetic analysis that included multiple samples per patient suggests overlapping driver mutations make their way into multiple metastases in each patient.
