BRIDGEWATER, N.J., Sept. 22, 2020 (GLOBE NEWSWIRE) -- Clinical Genomics (“CG” or the “Company”), a provider of cancer diagnostic solutions, including liquid biopsy tests for recurrence monitoring of colorectal cancer (CRC), today announced the publication of the NOVA clinical trial in the prestigious Cancer Epidemiology, Biomarkers & Prevention Journal. This U.S. population study further reinforces the performance of COLVERA®, the breakthrough blood test for the clinical presence of CRC recurrence in patients amenable to curative intent.
This peer-reviewed publication of the NOVA study was carried out in collaboration with 24 community and academic centers throughout the U.S. and included 322 patients undergoing standard of care recurrence surveillance after definitive treatment for stage II/III CRC. The findings further substantiate the importance of this blood test for post-treatment CRC patients. The data support findings observed in previous studies where COLVERA was shown to be more sensitive than CEA and identified more patients eligible to have their CRC recurrence treated with curative intent.1
The study’s lead author, Benjamin Musher, M.D., the Barry S. Smith Endowed Professor of Gastrointestinal Malignancies at the Dan L. Duncan Comprehensive Cancer Center, Baylor College of Medicine, stated that, “COLVERA outperformed CEA in detecting recurrences of colorectal cancer after definitive therapy. COLVERA therefore represents an important advance over the current standard of care for colorectal cancer surveillance.”
When compared with standard of care radiographic imaging, sensitivity for CRC recurrence was 63% (CI 42.4-80.6) and 48% (CI 28.7-68.1) for COLVERA and CEA (≥5ng/mL), respectively, while specificity was 91.5% (CI 87.7-94.4) and 96.3% (CI 93.4- 98.1), respectively. Smoking and age were independent predictors of CEA but not COLVERA positivity.
The primary objective of guideline-recommended surveillance after definitive treatment for CRC is early detection of recurrent disease when the disease is still amenable to potentially curative surgical resection2,3. Current blood-based detection methods, like CEA, experience limited sensitivity and can be false positive due to non-cancer conditions, such as smoking and chronic inflammatory diseases.
Detection of cancer-related epigenetic changes in circulating DNA (hypermethylation of BCAT1 and IKZF1 genes) using a single-time point COLVERA blood test was more sensitive than the current standard of care, CEA, for CRC recurrence detection. The improved sensitivity of COLVERA was not associated with race, age, gender and smoking.
“We are pleased that the findings of this new clinical study have been published in this preeminent journal. The use of a more sensitive assay during surveillance has the potential for enhanced detection of CRC recurrence and provides an opportunity for early curative intervention, and ultimately leading to improved patient outcomes in recurrent CRC,” stated Betsy Hanna, President and CEO of Clinical Genomics.

About Clinical Genomics
Clinical Genomics is dedicated to improving patient outcomes through early detection of colorectal cancer. Clinical Genomics’ products span the full spectrum of colorectal cancer testing from screening to post-treatment monitoring. Clinical Genomics is committed to developing and delivering solutions that provide physicians and their patients with information to help guide earlier and better treatment decisions in cancer care management.
About COLVERA
COLVERA is the first of its kind blood test to detect circulating tumor DNA for minimal residual disease (“MRD”) assessment and recurrence monitoring in patients previously diagnosed with colorectal cancer. COLVERA targets aberrant methylation of two genes (BCAT1 and IKZF1) and is mutation agnostic. COLVERA does not require any form of tissue biopsy prior to use. Introduced in 2017, COLVERA has been ordered by hundreds of colorectal surgeons and medical oncologists across the United States.
About Colorectal Cancer
Colorectal cancer is the third most commonly diagnosed cancer and the second-leading cause of cancer-related deaths in the United States, with more than 140,000 people per year expected to be diagnosed with CRC and over 50,000 succumbing to the disease annually. For patients who survive, 30%-50% will experience a recurrence, most within the first two to three years of primary treatment. On average, the lifetime risk of developing colorectal cancer is about one in 23 for men and women combined; however, this varies widely according to individual risk factors.
