Strata Oncology Launches Expanded StrataNGS
for Patients with Advanced Cancer

Updated StrataNGS test analyzes 500 cancer genes and reports status for three key
immunotherapy biomarkers to inform the use of precision therapies


Ann Arbor, Mich.  March 19, 2019 — Strata Oncology™, a leading precision oncology company, today announced the launch of version 3.0 of StrataNGS™, its pan-cancer assay for solid tumors. The updated 500-gene assay utilizes DNA and RNA from tumor samples to detect all clinically actionable biomarkers — including microsatellite instability (MSI), tumor mutational burden (TMB), and PD-L1 — recommended by leading guidelines, in a single test. Test results are provided in a streamlined report that facilitates rapid, confident interpretation and identification of potential treatment options and clinical trials.

“Our expanded assay, providing deep cancer insights and leading performance, represents our commitment to bring a best-in-class diagnostic to oncologists and pathologists across the Strata network of health systems,” said Scott Tomlins, M.D., Ph.D., Chief Medical Officer of Strata Oncology. “In addition to providing physicians with all relevant genomic information needed to make an informed treatment decision, the test will help inform new trial design and accelerate drug development.”

StrataNGS is provided at no cost to advanced cancer patients enrolled in the Strata Trial™ at the company’s partner health systems. Results are returned in less than 10 business days using industry-low sample input requirements. The test employs RNA sequencing and DNA sequencing to simultaneously detect mutations, small frame-preserving insertions/deletions (indels), amplifications, deep deletions, de novo deleterious mutations, gene fusion events, MSI, TMB, and PD-L1.

In addition, the updated assay includes analytical validation of 36 gene expression markers that represent emerging immuno-oncology and antibody-drug conjugate targets. Although these biomarkers are not yet reported clinically, the data is available to Strata Oncology and investigators at partner cancer centers for correlative analyses and new trial design.
