"We are pleased that the FoundationOne CDx Cancer Genomic Profile is now approved as a companion diagnostic against ROS1 fusion gene, which is one of the driver mutations in NSCLC. Although the frequency of ROS1 fusion gene expression in NSCLC is only about 1 to 2%1), treatment using ROS1 inhibitors can become one of the important therapeutic options for patients with ROS1-positive cancer," said Dr. Minoru Watanabe, Chugai’s Vice President, Head of Foundation Medicine Unit. "I am convinced that comprehensive cancer genomic profiling can further contribute to patients by enhancing its companion diagnostic functions. We will further expand companion diagnostic functions for both our in-house products and collaborations with biopharma partners."
Developed by Foundation Medicine Inc., FoundationOne CDx Cancer Genomic Profile is a next-generation sequencing based in vitro diagnostic device for the detection of substitutions, insertion and deletion alterations, and copy number alterations in 324 genes and select gene rearrangements, as well as genomic signatures including microsatellite instability (MSI) and tumor mutational burden (TMB) using DNA isolated from formalin-fixed, paraffin-embedded (FFPE) tumor tissue specimens. The program is available as a companion diagnostic for multiple molecular-targeted drugs approved in Japan.
As a leading company in the field of oncology, Chugai is committed to realize advanced personalized oncology care and contribute to patients and healthcare professionals through improving access to comprehensive genomic profiling.
