New Data Presented at ASTRO 2024 Show that Veracyte’s Decipher Prostate Test Predicts Aggressive Prostate Cancer in African American Men

Findings are from the prospective, multicenter VANDAAM trial

Veracyte, Inc. (Nasdaq: VCYT), a leading cancer diagnostics company, announced that new data from the multicenter, prospective VANDAAM trial show that the Decipher Prostate Genomic Classifier accurately predicts aggressive prostate cancer among African American men with early-stage disease. The findings confirm that the market-leading genomic test offers clinicians an improvement over clinical factors alone in guiding prostate cancer treatment decisions for African American men, a population that is disproportionately impacted by the disease. The new data were shared today in an oral presentation at ASTRO 2024, the annual meeting of the American Society for Radiation Oncology, in Washington, D.C.

African American men are more than 70% as likely to be diagnosed with prostate cancer and more than twice as likely to die of the disease, compared to white men, according to the American Cancer Society.¹ Despite this, few prospective studies have specifically sought to examine the disease at a genomic level in this population.

“We intentionally recruited African American men into the VANDAAM trial to enable a one-to-one match with non-African American men with similar clinical factors,” said Kosj Yamoah, M.D., Ph.D., chair of the Department of Radiation Oncology at the H. Lee Moffitt Cancer Center & Research Institute and presenter of the data at the ASTRO meeting. “Our results showed that the Decipher Prostate test was highly accurate in predicting aggressive prostate cancer in both groups. These findings confirm that use of the genomic test in African American men could potentially enable better treatment decisions and outcomes, helping to reduce outcome disparities for this population.”

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 evaluated data for a clinically balanced cohort of 226 men (113 African American men and 113 non-African American men) and performed genomic analysis using the Decipher Prostate classifier to generate Decipher risk scores.

Following standard treatment, patients with high Decipher test scores were eight times more likely to have biochemical recurrence within 2 years (BCR; i.e., a rise of prostate-specific antigen levels in the blood, which was used as a surrogate for aggressive disease), compared to those with lower genomic test scores (HR = 7.93, 95% CI, 1.65 – 33.04, p = 0.008). When adjusted for other variables, such as age, race, pre-treatment prostate specific antigen (PSA), and Gleason score, those patients with high Decipher test scores remained at significantly high risk of rapid-onset BCR (HR = 10.37, 95% CI, 1.94-55.35, p = .006). There was no significant difference in the results between African American and non-African American men.

“The Decipher Prostate test’s ability to accurately predict risk of a patient’s prostate cancer progressing has already been demonstrated in dozens of clinical studies,” said Elai Davicioni, Ph.D., Veracyte’s medical director for Urology. “While prior retrospective data showed that Decipher is highly prognostic in African Americans, these patients have historically been under-represented in biomarker clinical studies. We applaud the VANDAAM study team for conducting the first prospective clinical trial to examine the effectiveness of genomic risk-stratification in African American men – results that could potentially help to narrow the prostate cancer disparity gap.”

“These new data further demonstrate the power of the Veracyte Diagnostics Platform to further our mission of transforming cancer care for all patients,” said Marc Stapley, Veracyte’s chief executive officer. “Our comprehensive, whole-transcriptome approach enables us to develop high-performing tests, such as Decipher Prostate, that are validated across different patient populations and can help address differences in tumor biology and minimize disparities in outcomes. We believe this ability is key to helping to overcome gaps in cancer care.”

About Decipher Prostate

The Decipher Prostate Genomic Classifier is a 22-gene test, developed using RNA whole-transcriptome analysis and machine learning, that helps inform treatment decisions for patients with prostate cancer. The test is performed on biopsy or surgically resected samples and provides an accurate risk of developing metastasis with standard treatment. Armed with this information, physicians can better personalize their patients’ care and may recommend less-intensive options for those at lower risk or earlier, more-intensive treatment for those at higher risk of metastasis. The Decipher Prostate test has been validated in many dozens of published studies involving more than 100,000 patients and is the only gene expression test to achieve ‘Level 1B’ evidence status in the most recent NCCN^® Guidelines* for prostate cancer.
