SOPHiA GENETICS and Myriad Genetics announce new collaboration to advance prostate genomic instability score technology. 08 Oct, 2026, 18:30 IST BOSTON, Oct. 8, 2026 /PRNewswire/ - SOPHiA GENETICS (NASDAQ: SOPH) and Myriad Genetics, Inc., (NASDAQ: MYGN) today announce a collaboration to advance new prostate cancer-specific genomic instability score (PrGIS) technology to support precision oncology approaches with AstraZeneca (LSE/STO/NYSE: AZN). PrGIS is a novel biomarker signature designed to assess chromosomal instability associated with homologous recombination deficiency (HRD) in prostate cancer patients. The collaboration aims to advance PrGIS in clinical trials and expand access to precision oncology medicines through potential companion diagnostic solutions. Myriad developed PrGIS to support HRD as an actionable biomarker in prostate cancer, where HRD is emerging as an important prognostic and predictive biomarker. The proprietary MyChoice(R) CDx test which is currently available as a companion diagnostic in ovarian cancer, will produce the PrGIS score and is being advanced for prostate cancer as a new indication. "This collaboration showcases Myriad's biopharma capabilities to support development of precision oncology treatments," said Lou Welebob, Senior Vice President, Companion Diagnostics, Myriad Genetics. "PrGIS is designed to provide biopharma partners with a platform that may support patient stratification in clinical trials and help accelerate companion diagnostic development for precision oncology therapies." As part of the collaboration, SOPHiA GENETICS is developing its solid tumor application for Extended Homologous Recombination Solution into a decentralized companion diagnostic solution. The solution will incorporate Myriad's PrGIS technology and aim to expand patient access to PrGIS in global markets. SOPHiA GENETICS' technology-agnostic, cloud-based platform offers local laboratory testing across a global network of more than 1,000 connected institutions in over 75 countries. "Precision medicine has a geographic problem because breakthrough therapies developed in major markets often remain inaccessible to patients in the rest of the world," said Jess Lambe, VP & Managing Director of BioPharma Business Development, SOPHiA GENETICS. "By pairing Myriad's world-class biomarker innovation with SOPHiA GENETICS' global network, we are working toward a solution for this. Together, we're building a new model for companion diagnostic deployment that could help innovative therapies reach the right patients locally, expanding access to care where it matters the most." Upcoming ESMO data to highlight PrGIS as a novel biomarker in prostate cancer Myriad also plans to present PrGIS research, co-authored with AstraZeneca, at the upcoming European Society for Medical Oncology (ESMO) Congress 2026. The research is expected to further characterize the biomarker and support its validation. Full data will be available following the ESMO embargo period.
