Paris, France, and Hennigsdorf/Berlin, Germany, August 31, 2019 - Diagnostics company SphingoTec GmbH (“sphingotec”, Hennigsdorf near Berlin, Germany) today launched IB10 sphingotest® DPP3, the first CE-IVD-marked point-of-care biomarker test able to quantify DPP3 blood-plasma levels, a novel and unique biomarker predicting outcomes in patients with cardiogenic shock at admission to intensive care units (ICUs). The DPP3 biomarker indicates angiotensin II and enkephalin signaling pathway disruptions leading to acute, short-term organ dysfunction. sphingotec will make the test initially available to the critical care community for further assessment of the clinical utility of the DPP3biomarkerin critical care settings. The assay is designed and validated for use with sphingotec’s fully automated Nexus IB10 whole blood point-of-care platform for rapid testing in laboratories, emergency departments and intensive care units together with a menu of standard critical care tests also available on the Nexus IB10 instrument.

DPP3 is at the core of a novel disease mechanism presented by Prof. Alexandre Mebazaa (Hôpital Lariboisière, Paris) today at ESC Congress 2019 (organised by the European Society of Cardiology ESC, Paris) and was described in detail in two high-ranking peer-reviewed publications by Prof. Mebazaa and co-workers also published today1,2.Results from independent clinical studies provide evidence that outcomes of patients with cardiogenic shock are associated with DPP3 blood concentrations. The scientists hypothesize that DPP3 is released from cells into the bloodstream upon cell death and degrades central mediators of cardiovascular function, angiotensin II as well as kidney function mediator enkephalin.

In blood samples from patients with cardiogenic shock enrolled in the OptimaCC3(N=57) and the CardShock4 (174 patients) studies, sustained high or increasing DPP3 plasma levels were associated with a significantly reduced cardiac left ventricular ejection fraction, impaired kidney function, and a markedly increased risk of mortality while decreasing levels of DPP3 were associated with higher survival. The causal role of DPP3 was further substantiated by studies in pre-clinical models in which injection of DPP3 impaired heart and kidney function. All these effects were immediately reversed in vivo following administration of the pre-clinical stage anti-DPP3 antibody Procizumab in a severe acute heart failure model. Procizumab is developed by the biopharmaceutical company 4TEEN4 Pharmaceuticals GmbH (“4TEEN4”). 4TEEN4 has recently licensed DPP3 rights to sphingotec for diagnostic purposes.

“DPP3 represents a unique biomarker at the core of a novel disease mechanism with high potential utility in diagnosing organ dysfunction and predicting outcome in cardiogenic shock as well as in a range of other acute care indications”, said Prof. Mebazaa.

Dr. Andreas Bergmann, CEO and founder of sphingotec commented: “The new disease mechanism investigated by Prof Mebazaa has huge potential to provide novel diagnostic and therapeutic options in a range of acute care settings with high unmet clinical need. To better understand clinical utility of DPP3 in the management of acute care patients, we invite the critical care community to collaborate with us in the further evaluation of this promising biomarker with our fully automated DPP3 point-of-care test in laboratory and near-patient settings.”

About Acute Heart Failure

Heart failure is a state of reduced cardiac output, in which the heart cannot pump blood through the body effectively. When symptoms appear suddenly, or a person experiences rapid worsening of existing symptoms of heart failure, this is called acute heart failure (AHF) or acute decompensated heart failure (ADHF). This condition can be life threatening and should be urgently evaluated by a physician, as outcomes can be affected by early and appropriate treatment. Heart failure is a common condition affecting more than 30 million people world-wide. Typical symptoms of acute heart failure include shortness of breath, tiredness and swelling of the feet and legs (congestion). Treatment typically involves supporting breathing and adjusting the blood pressure and, where necessary, removing excess fluid from the body by diuretic treatment. There is no cure, but long-term treatment involving medications and rehabilitation can improve the heart’s function.

About Cardiogenic Shock

Cardiogenic shock is an emergency with mortality rates up to 50 %. Most cases of cardiogenic shock occur after myocardial infarction and are defined by persistent low cardiac output state resulting in arterial hypotension, shortness of breath, reduced organ perfusion. Refractory cardiogenic shock presents as persistent organ hypoperfusion despite the administration of vasoactive treatments. Early initiation of mechanical circulatory support, early percutaneous coronary intervention, inotropes, and heart transplantation may improve outcomes for patients with cardiogenic shock.

About DPP3

Human Dipeptidyl Peptidase 3 (DPP3) is an ubiquitously expressed and highly conserved enzyme. DPP3 cleaves various bioactive peptides, such as such as angiotensin II, enkephalins. The most prominent substrate of DPP3 is angiotensin II, the central effector of the renin–angiotensin system (RAS), implicating extracellular DPP3 in the regulation of the RAS. RAS is activated in cardiovascular diseases, sepsis and septic shock and angiotensin II, in particular, has been shown to modulate many cardiovascular functions including the control of blood pressure and cardiac remodelling.

In a prospective, real-world study of 1,436 critically ill ICU patients, proenkephalin A 119–159 (penKid) provided clinically relevant information across AKI severity and during kidney replacement therapy (KRT). PenKid addressed a key unmet need in KRT management by identifying, with greater precision than standard biomarkers, patients at high risk of KRT liberation failure – helping to avoid stopping therapy too early. The findings support a future role for penKid in helping to standardize one of the few intensive care processes where the need for better decision support is widely acknowledged and current tools remain insufficient. Hennigsdorf, Germany – August 27, 2026 – SphingoTec GmbH announces the publication of new real-world data on proenkephalin A 119–159 (penKid) in critically ill patients. The data, published in Annals of Intensive Care, add to the growing body of evidence supporting penKid as a functional biomarker for kidney function and help inform clinical decision-making in AKI and KRT (1). In a prospective observational study at Heidelberg University Hospital, penKid was measured in 1,436 critically ill patients, including 138 patients receiving KRT for liberation analyses. The findings showed that penKid rose with AKI severity and, unlike serum creatinine and urine output, distinguished stage 3 AKI patients with and without an acute KRT requirement. In contrast to serum creatinine, penKid also differentiated acute KRT patients from those with pre-existing kidney failure and on chronic hemodialysis prior ICU admission, even while KRT treatment was ongoing (1). The study further showed that penKid levels increased progressively from the start of KRT, while serum creatinine decreased under treatment. Following successful liberation from KRT, penKid declined, whereas higher levels were seen in cases of liberation failure. In multivariable analysis, penKid was the strongest independent predictor of liberation failure and outperformed serum creatinine. A penKid cut-off of ≥250 pmol/L provided more than 90% specificity for liberation failure (1). By identifying patients at high risk of unsuccessful liberation, penKid may help clinicians make KRT discontinuation decisions more objectively, reduce the risk of stopping therapy too early, and support more standardized decision-making across critical care settings. “These data are important because they address a real-world clinical problem: how to better assess kidney function and support KRT decisions when standard markers fall short,” said Deborah Bergmann, CEO of SphingoTec. “penKid provides clinicians with an objective, real-time measurable parameter that may help support more informed and consistent kidney-related decisions in critical care.” Christian Nusshag, MD, Department of Nephrology, Heidelberg University Hospital, said: “Current markers often leave clinicians with an incomplete picture. Our findings suggest that penKid may help standardize decision-making by providing additional, actionable information on kidney integrity and recovery.” About penKid, scientific insights PenKid is a biomarker that enables real-time assessment of kidney function. Unlike conventional markers such as serum creatinine, penKid levels are not influenced by inflammation or other confounding factors like age or sex. Studies have shown that penKid allows earlier detection of AKI, predicting changes in serum creatinine up to 48 hours before conventional diagnostic criteria are met. This early detection capability is particularly valuable in critically ill patients, including those with sepsis or septic shock. Additionally, penKid has shown potential for monitoring renal recovery under KRT and could help predict successful liberation from KRT.
