Excerpt from GenomeWeb:
“Researchers from Genentech, Foundation Medicine, UC Davis, and other medical centers, have published a report on the development and early validation of Foundation’s planned blood-based tumor mutational burden test.
“Appearing today in Nature Medicine, the study describes the development of the test and its characteristics, and its retrospective validation in two cohorts. Investigators demonstrated, by applying the assay to samples from two clinical trials, that blood-based TMB (bTMB) could reproducibly identify lung cancer patients who respond to immunotherapy treatment with Roche/Genentech’s atezolizumab (Tecentriq).”
