We Develop Patient-First Technology   

It has often been said that the best tests are easily recognized because they are the ones being used. That’s why we specialize in using already-existing technologies that can be employed for earlier cancer detection and screening  purposes. Through this approach, we are able to create highly accurate tests for cancer screening and detection that are affordable and can be readily adopted.

Signaling Protein Based Test

 The foundational protein for Beacon's laboratory developed test is called teratocarcinoma derived growth factor-1, aka Cripto-1, and was licensed from the National Institutes of Health and National Cancer Institute for exclusive use by Beacon to develop and commercialize laboratory developed tests and test kits for early cancer recognition, detection, screening and monitoring purposes. Cripto-1 is a required protein for tumor formation, progression and invasion, and has been detected in 50-100% of carcinomas of the breast, colon, lung, pancreas, gallbladder, stomach, endometrium and cervix.

Laboratory Developed Test

BeScreened™-CRC is an ELISA-based multiplexed, CLIA laboratory developed colorectal cancer (CRC) screening test.  The test used three blood-based tumor-associated protein biomarkers; a patented oncoprotein called teratocarcinoma derived growth factor-1 (TDGF-1, Cripto-1); carcinoembryonic antigen (CEA), a well-established biomarker associated with CRC; and an extracellular matrix protein involved in early stage tumor stroma changes. These three proteins are intimately involved in the structure, function, and regulation of activities associated with CRC tumorigenesis; generation, invasion, progression and migration.

BeScreened-CRC was developed exclusively by Beacon Biomedical, Inc. Beacon is certified under CLIA to perform high complexity clinical laboratory testing and is providing BeScreened-CRC to the public as alternate test option for CRC screening test to those individuals who are unwilling or unable to use existing recommended fecal-based screening test or imaging procedures.  This test’s performance characteristics has been established by Beacon Biomedical in a cross-sectional study in patients of both genders, 50 years of age or older, and who are at typical average-risk for colorectal cancer.

The  assay results are processed through Beacon’s proprietary relational algorithm and evaluated against the algorithm’s healthy patient-state status criteria. Patients that fall within the acceptance criteria are reported as negative for the likely presence of CRC with a recommendation to stay compliant with their individual healthcare and screening needs. Patients calculated as outliers to that same criteria are reported as positive with an elevated-risk of CRC’s presence with a recommendation to follow-up with their physician to schedule a screening colonoscopy.

As a laboratory developed test (LDT) under the Centers for Medicare and Medicaid Services’ (CMS’) Clinical Laboratory Improvement Amendments (CLIA), BeScreened-CRC is approved for clinical use and it does not require FDA clearance or approval.
