Nordic Bioscience launches novel Endotrophin assay

HERLEV, Denmark, May 16, 2025 /PRNewswire/ -- Nordic Bioscience introduces nordicEndotrophin™, 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 studies¹.

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 countries². 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%^1,2. 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 insights¹.

"Endotrophin is a significant prognostic biomarker to emerge," said CEO Dr. Morten Karsdal. "Evidenced in a study of HFpEF patients, Endotrophin and PRO-C6 outperformed NT-proBNP in HFpEF for mortality and hospitalization risk³. 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. To accelerate drug fibro-inflammatory profiling, clients considering nordicEndotrophin™ are invited to co-measure nordicPRO-C3™ and nordicPRO-C6™. Together, these assays facilitate precise risk stratification, dose selection, patient enrichment, proof-of-mechanism and treatment monitoring in anti-fibrotic and oncology trials².
