[{"type":"text","content":"\n- First validation of a gene expression classifier in pre-treatment biopsy samples from prospective randomized trials -\n\n SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--\nVeracyte, Inc. (Nasdaq: VCYT) announced today that new data being presented at the American Society for Radiation Oncology (ASTRO) 2021 Annual Meeting suggest the company’s Decipher Prostate genomic classifier identifies patients with clinically high-risk prostate cancer who may require treatment intensification beyond standard-of-care therapy.\n\nThe findings, from a pre-specified analysis of biopsy samples taken from prostate cancer patients with clinically high-risk disease who were enrolled in multiple phase 3, prospective, randomized studies, show that Decipher Prostate test scores are independently associated with distant metastases (DM), prostate cancer-specific mortality (PCSM) and overall survival (OS) in this patient population. After a median follow up of 11 years, men with disease classified as Decipher high-risk experienced substantially less favorable outcomes compared to men with disease classified as Decipher low-risk.\n\n“Clinically high-risk prostate cancer is a heterogenous disease, and having reliable information about individual patients’ prognoses based on their unique tumor biology can help improve shared decision-making,” said Paul L. Nguyen, M.D., of the Dana-Farber Brigham Cancer Center, who presented the data during an ASTRO media briefing today. “The findings we’re sharing at ASTRO are particularly exciting because they are the first to validate use of a gene expression classifier in pre-treatment prostate cancer biopsy samples collected during prospective, randomized clinical trials.”\n\nFor the analysis, Dr. Nguyen and colleagues obtained Decipher Prostate scores for 265 biopsy samples from the NRG/RTOG 9202, 9413 and 9902 phase 3 randomized trials. After multi-variable analyses adjusting for age, prostate-specific antigen (PSA) levels, Gleason score, cT-stage, trial and randomized treatment arm, researchers found that Decipher Prostate scores were independently associated with distant metastases (HR 1.24), prostate cancer-specific mortality (1.27) and overall survival (1.12). The cumulative incidence of DM at 10 years was 26%, 15% and 6% for men who were Decipher high-risk, intermediate-risk and low-risk, respectively. Among th...
