SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--Veracyte, Inc. (Nasdaq: VCYT) announced that data published today in the Journal of the National Cancer Institute demonstrate that the company’s Decipher Prostate Genomic Classifier may help identify African American men with early, localized prostate cancer who are most likely to harbor more aggressive disease. The data, from the prospective, multi-site VANDAAM Phase 2 clinical study, suggest that the genomic test may offer a robust improvement over clinical factors alone in risk-stratifying prostate cancer among African American men, which may help reduce disparities in prostate cancer outcomes.
“While African American men have both higher incidence and mortality associated with prostate cancer, few prospective studies maximize recruitment of these men to provide an unbiased assessment of the genomic processes that underlie these disparities,” said Kosj Yamoah, MD, Ph.D., chair, Department of Radiation Oncology, Moffitt Cancer Center, and lead author on the published paper. “We very intentionally recruited a balanced sample of men into this study, but prioritized recruitment of African American men first in order to ensure we had a representative sample of this population, which historically has been underserved in prostate cancer clinical trials. The integration of the Decipher classifier with traditional clinical risk factors was shown to improve identification of the subset of African American men with more aggressive disease. This information could help guide targeted interventions and treatment strategies to improve outcomes in this population.”
The Decipher Prostate Genomic Classifier is a 22-gene prognostic biomarker that provides a low, intermediate or high score indicating the aggressiveness of an individual patient’s cancer, to help healthcare professionals more accurately categorize risk and select appropriate treatment.
The VANDAAM trial enrolled men with low- or intermediate-risk prostate cancer as classified by the National Comprehensive Cancer Network (NCCN) Guidelines® for Prostate Cancer. For the current analysis, researchers identified a clinically balanced cohort of 226 men (113 African American men and 113 non-African American men) from the study and performed genomic analysis using the Decipher Prostate classifier to generate Decipher risk scores.
Results show that a higher proportion of African American men with NCCN low and favorable intermediate risk prostate cancer (18% and 37.8%, respectively) had higher Decipher scores as compared to non-African American men. Men who self-identified as African American were more than twice as likely as non-African American men to have their cancer re-classified from NCCN low or intermediate risk based on a high Decipher score (known as genomic risk of reclassification or GrR; relative risk = 2.23; 95% CI). In addition, the data show that younger African American men had higher Decipher scores, whereas in non-African American men, higher risk of metastasis scores were observed in older men.
“This study demonstrates that prostate cancer risk classification using clinical factors alone may be suboptimal and may underestimate African American men’s risk of harboring aggressive disease,” said Elai Davicioni, Ph.D., Veracyte’s medical director, Urology. “We commend the study team for undertaking the first prospective trial to utilize genomic classifiers as part of the trial design, as well as for their efforts to help close the clinical disparity gap by improving risk stratification among African American men with prostate cancer.”
