Aachen, Germany and Hennigsdorf/Berlin, German, December 10, 2020
– The Uniklinik RWTH Aachen (“Uniklinik RWTH Aachen”) has successfully translated the collaboration for research and biomarker validation with SphingoTec GmbH (“SphingoTec”) into clinical routine. The routine measurements of the innovative biomarkers are providing organ-specific information for monitoring critical care conditions such as sepsis and acute kidney injury and support clinical decisions to improve patient outcomes.
Uniklinik RWTH Aachen is one of Germany’s most modern hospitals due to the way it integrates diagnostics and therapy, research and teaching under the same roof. Following a patient-centric approach, Uniklinik RWTH Aachen has adopted innovative pathways in intensive medicine by introducing these new diagnostic tools for monitoring organ function of critically ill patients. The routine measurements of penKid® and bio-ADM® provide clinicians with more insights on the disease pathology and etiology of clinical symptoms and facilitate more efficient, timely, and adequate treatment.
Prof. Dr. Gernot Marx, the Director of the Clinic for Operative Intensive Care and Intermediate Care at Uniklinik RWTH Aachen explained: “Critically ill patients are highly dynamic with many complications interfering in the diagnostics process, thus a very challenging environment for introducing innovations. We have been looking for a long time for the right diagnostic tools to allow us a faster and better diagnosis, risk stratification, and monitoring of the disease progression so that we can provide the best available treatment immediately for acute cases. The first routine measurements do confirm the utility and value of these novel diagnostic biomarkers in clinical decision-making and ultimately in maximizing the patient’s benefit. “
In intensive care units, 1 in 3 patients is developing acute kidney injury [1]. The existing diagnostic parameters for the determination of renal function or kidney damage, which are routinely used as standard procedure, have a considerable time delay or are influenced by inflammation or other diseases. These limitations are underlining the need for more precise tools to support clinical decisions. The biomarker penKid® offers real-time information about the kidney function with the first measurement and without being influenced by co-morbidities or the frequently occurring inflammation in critically ill patients [2,3,4]. Moreover, penKid® shows the best representation of the current kidney function, measured by the glomerular filtration rate (true GFR). [5]
World-wide, sepsis is accountable for 1 in 5 deaths [6]. Reduced organ perfusion in shock, which can be determined by existing laboratory values, is the culprit for the fatal course, but it can be induced by various factors. The loss of endothelial function is often a main cause for shock in sepsis, but it could not be detected by blood-based tests so far. The measurement of the bio-ADM® biomarker now allows for the first time the direct assessment of endothelial function in real time [7,8,9] independent of co-morbidities and inflammation, thus supporting precise and rapid treatment decisions.
Dr. Andreas Bergmann, founder and CEO of SphingoTec added: “We are excited that the initial clinical evaluation ended in a successful translation of the biomarkers into clinical routine. The comprehensive amount of routine data on our biomarkers collected by Prof. Gernot Marx and his team will allow us to deepen our knowledge of the biomarkers and to explore further application areas. Encouraged by this implementation of our novel diagnostic tools at the frontlines of medical care, we intend to offer them in a near future on a larger scale in other European countries.”

About penKid®
sphingotest® penKid® measures Proenkephalin (penKid®), a stable fragment of the kidney stimulating hormone Enkephalin. penKid® has been demonstrated to be a real-time surrogate biomarker for glomerular filtration rate, the gold standard to assess renal function. Measuring penKid® blood concentrations allows for timely information on kidney function in critically ill patients. Early assessment of worsening and improving of renal function on intensive care units and in emergency departments allows adjustment of nephrotoxic drug administration and the initiation of kidney-protective strategies to prevent acute kidney injury and thereby improve outcomes.

About bio-ADM®
sphingotest® bio-ADM® measures bioactive Adrenomedullin (bio-ADM®), a hormone maintaining endothelial function. The endothelium contributes to blood pressure and separates blood from the surrounding tissue. Elevated blood levels of bio-ADM® predict blood pressure break down and leaky vessels resulting in oedema. Imbalanced endothelial function is the major cause of shock ultimately resulting in organ dysfunction and death. Early identification of an imbalance in endothelial function allows guidance of vasopressor and diuretic therapy in critically ill patients to improve outcomes.

• PenKid surpasses serum creatinine on Day 1 post-transplant in detecting delayed graft function (DGF), with an AUROC of 0.87 versus 0.56 for creatinine. • PenKid differentiates slow graft function (SGF) from DGF up to 8 days earlier than current methods, supporting more timely clinical decisions. • PenKid levels remain unaffected by kidney replacement therapy (KRT), allowing for more accurate assessment of kidney function. • Independent validation in transplant cohort from Australia confirms performance and broad applicability. Hennigsdorf/Berlin, Germany, July 1, 2025 - Diagnostic company SphingoTec GmbH (“SphingoTec”) announces a landmark study (1) published in Transplant International, led by Heidelberg University Hospital in Germany in collaboration with researchers from Sydney, Australia, which identifies Proenkephalin A 119-159 (penKid) as a reliable biomarker for early and precise assessment of graft function trajectories following kidney transplantation. The research demonstrates that PenKid not only identifies patients at risk for DGF significantly earlier than traditional markers but also distinguishes between slow and delayed graft function with remarkable accuracy, offering clinicians a valuable new tool for patient management. The study prospectively evaluated 159 consecutive kidney transplant recipients at Heidelberg University Hospital and validated findings in an independent cohort from Sydney. PenKid consistently outperformed serum creatinine (SCr) in predicting graft function trajectories, particularly in the critical early post-transplant period. Notably, PenKid’s ability to remain unaffected by KRT—a treatment for severe kidney dysfunction—further sets it apart from SCr, which can be influenced by non-renal factors and KRT itself, thereby enhancing the reliability of graft function assessment. Multivariate analysis confirmed PenKid as the strongest independent predictor of both short-term graft function and 30-day outcomes, underscoring its clinical utility for early risk stratification. The biomarker’s superior granularity allows for nuanced classification of DGF severity, supporting more informed decisions regarding the initiation of dialysis or biopsy and offering potential for individualized patient care. With these findings, penKid steps forward as a practical addition to the transplant clinician’s toolkit, promising to sharpen decision-making for optimal outcomes. Its adoption could help transplant teams act with greater confidence and precision, ultimately strengthening the standard of care in kidney transplantation. ## References 1. Benning L et al.

Unlike traditional markers such as serum creatinine, penKid levels are not influenced by inflammation or other confounding factors like age or sex (1,2,3). Studies have shown that penKid allows earlier detection of acute kidney injury (AKI), predicting changes in serum creatinine up to 48 hours before conventional diagnostic criteria are met (1,3). This early detection capability is particularly valuable in critically ill patients, including those with sepsis or septic shock (1,3,4). Additionally, penKid has shown potential for monitoring renal recovery under dialysis and could help predict successful weaning from renal replacement therapy (5,6). ## References 1.
