Caris Life Sciences to Present Initial Study Results for Blood-Based Prostate Cancer Test at AACR Annual Meeting

Caris scientists and collaborators to also present posters on colorectal cancer biomarkers, mutations in the CYLD gene, mutations in head and neck squamous cell carcinoma, and PD-L1 expression
IRVING, Texas, March 27, 2019 – Caris Life Sciences®, a leading innovator in molecular science focused on fulfilling the promise of precision medicine, today announced that it will present initial validation of a blood-based prostate cancer assay at the American Association for Cancer Research (AACR) Annual Meeting being held March 29-April 3, 2019, at the Georgia World Conference Center in Atlanta. Caris President and Chief Scientific Officer Dr. David Spetzler will detail the results of a study on the assay during his oral presentation, “Poly-ligand Profiling of Plasma Samples as a Potential Predictor of Prostate Biopsy Results,” on Monday, April 1, from 4:35 – 4:50 p.m. Eastern in Room A315.
Caris developed the new blood-based prostate cancer test as part of an effort to improve the accuracy of prostate cancer screening and reduce the need for unnecessary prostate biopsies. With its proprietary profiling platform, ADAPT Biotargeting System™, the company used single stranded oligonucleotide (ssODN) libraries to perform poly-ligand profiling on plasma exosomes from men scheduled for biopsy to classify those with or without a subsequent diagnosis of prostate cancer. Results suggest that poly-ligand profiling may provide an additional approach to stratify men with suspicious PSA levels for prostate biopsies.
“We are encouraged by the results of this study, which indicate that a blood test has the potential to accurately identify prostate cancer prior to an invasive biopsy,” said Dr. Spetzler. “ADAPT is advancing diagnostics, and we hope that with further study, prostate cancer screenings will be made easier and less invasive by using a blood-based approach.”
The ADAPT Biotargeting System™ is an innovative and versatile unbiased profiling platform that identifies novel molecular targets to inform and enhance drug development and advanced diagnostics. It can measure thousands of protein aberrations and is being used to develop early cancer detection assays, discover novel drug targets, and characterize protein differences in cancers.
In addition to Dr. Spetzler’s oral presentation, Caris scientists and collaborators, comprised of experts from leading cancer centers around the world, will present four poster presentations at the AACR Annual Meeting:
