NTRK Fusion Testing for New Therapies

Detecting & Managing Rare Pediatric & Adult Cancers

Posted by Omo Clement, Ph.D. on Feb 6, 2019 9:15:00 AM

Neurotrophic tyrosine receptor kinases (NTRK) can become abnormally fused to other genes resulting in growth signals that can lead to cancer in many organs of the human body. TRK gene fusion-based cancers are rare but present in pediatric and adult cancers such as lung, thyroid, colon, etc. (see, e.g., Figure 1).

Building and Implementing Liquid Biopsy Assays with the Industry’s Most Patient-Like Reference Materials

Posted by Omo Clement, Ph.D. on Oct 24, 2018 9:00:00 AM

SeraCare’s clinical genomics technologies are developed to address challenges faced across the spectrum of NGS assays. From early development of assays – either IVD assay manufacturers or clinical labs building their own LDTs - there is a scarcity of characterized, complex, difficult variants to ensure the assay can robustly detect all the critical genomic variants in a patient sample. Using our highly characterized, reproducible, and GMP-grade NGS standards, laboratories have a wide range of analytical and clinical validation tools to deeply characterize assay performance such as LOD, linearity, specificity, sensitivity, and reproducibility.

How A New Generation of ctDNA Reference Standards Are Enabling the Promise of Precision Medicine

Posted by Omo Clement, Ph.D. on Jun 14, 2018 10:00:00 AM

An important goal in cancer disease management is early detection. When detected early, disease progression can be significantly mitigated with a plethora of options (targeted therapy, chemotherapy, surgery, etc.) available to medical practitioners, to afford progression free survival and a higher quality of life. A great promise of liquid biopsies is the possibility of early detection of cancer long before clear evidence of lesions and tumor growth observable by imaging or other techniques.1 As proxy for solid tissue biopsies, plasma-based liquid biopsy application is rapidly gaining traction in cancer disease diagnosis, progression, monitoring, and in predicting resistance to treatment options.2
