Resolution Liquid Biopsy Assay Detects More Actionable Oncogenic Fusions With Higher Allele Frequency than Guardant360

The comparison study highlights detection challenges of complex mutations such as gene fusions, as well as the need for platform cross-comparisons to realize the potential of liquid biopsy and increase access to personalized cancer care. A cohort of 169 non-small cell lung cancer (NSCLC) patients with Guardant360 results were screened for gene fusions. The team of scientists at Dana-Farber used a soon-to-be-released ctDx-Lung kit to analyze 16 cases that had a rearrangement in their tumor, along with additional banked plasma. All personnel involved in sample analysis were blinded to tumor genotype and Guardant360 results. The team found that the Resolution ctDx-Lung assay identified more actionable gene fusion mutations with higher allele frequencies than the Guardant360 test. The results further demonstrate the potential of the ctDx-Lung kit for patients with advanced NSCLC.

Paweletz, PhD, of the Belfer at Dana-Farber Cancer Institute can reference abstract 1374/13. The study will be presented on April 1, 2019 between 8 AM-12 PM in Section 19 of the Georgia World Congress Center Exhibit Hall.

About Resolution ctDx-Lung™

ctDx-Lung is built on Resolution’s patented cell-free DNA NGS analysis platform. The liquid biopsy assay captures and analyzes circulating tumor DNA (ctDNA) for driver mutations in 20 genes associated with NSCLC using Resolution’s proprietary targeted capture NGS chemistry and cloud-based bioinformatics.
