Nordic Bioscience has introduced Nordic Endotrophin, a fully automated high-precision assay that selectively quantifies the intact 77-amino-acid Endotrophin signaling hormone, qualified in the CAP/CLIA certified Nordic Bioscience laboratory. When integrated with the company's existing product line, the biomarker assay demonstrated prognostic utility in fibrosis and cancer studies.

NordicEndotrophin joins nordicPRO-C6 and nordicPRO-C3 – in-house versions of the FDA-supported PRO-C6 and CE approved PRO-C3 assays, to deliver a one-stop solution for assessing the fibro-inflammatory axis in chronic diseases, including cardiovascular, metabolic, renal and more. Following PRO-C3's recent deployment on Roche IVD platforms, the new Endotrophin assay strengthens risk stratification and pharmacodynamic monitoring.

Endotrophin was first identified in 2012 as a collagen-derived hormone released from type VI collagen. Type VI collagen is a contributor to fibroblast activation and driver of fibrosis across organs—inflammatory processes that underlie roughly 40 percent of deaths in Western countries.

Obesity exacerbates this by activating fibroblasts in the liver, kidney and heart. Across a range of chronic diseases, patients with a two-fold increase of circulating Endotrophin levels increased risk of mortality by 100 percent. Quantifying Endotrophin enables researchers to connect wound healing and fibrotic progression to patient outcomes, supporting precision-medicine approaches that pharmacodynamically modulate this dangerous hormone.

Whereas PRO-C6, Nordic Bioscience's first hand-held ELISA assay measuring the formation of the total pool of type VI collagen (a3 chain encompassing 12 Von Willebrand binding domains), a collagen responsible for binding of platelets that cause fibroblast activation and would healing, nordicEndotrophin specifically measures the intact 77-amino-acid hormone. This specificity means additional risk stratification and prognostic value that complement PRO-C6's fibrosis-driven pharmacodynamic insights.

Dr. Morten Karsdal, CEO, Nordic Bioscience said, “Endotrophin is a significant prognostic biomarker to emerge. Evidenced in a study of HFpEF patients, Endotrophin and PRO-C6 outperformed NT-proBNP in HFpEF for mortality and hospitalization risk. Together with PRO-C3, quantifying this fibro-inflammatory hormone will refine patient stratification and treatment monitoring across obesity, fibrotic diseases, and autoimmune endotypes.”

Offered in Nordic Bioscience's CAP/CLIA-certified laboratory in Herlev, Denmark, the nordicEndotrophin high-precision sandwich assay is available on fully automated, high-accuracy, high-throughput platforms.
