sphingotec’s endothelial function biomarker bio-ADM® predicts need for organ support in general ICU patient population

  • Data from more than 2,000 patients enrolled in the FROG-ICU study demonstrate that high levels of bioactive adrenomedullin (bio-ADM®) predict the need for organ support, ionotropes, and vasopressors in the general patient population at admission to the intensive care unit (ICU).
  • bio-ADM® screening of patients admitted for septic or non-septic reasons supports stratification of risk patients that need immediate therapeutic intervention due to an elevated risk of organ failure.
  • sphingotec will launch a CE-marked IVD point-of-care assay for bio-ADM® rapid testing on its proprietary Nexus IB10 immunoassay platform in mid-2020.
Hennigsdorf/Berlin, Germany, December 23, 2019 - Diagnostics company SphingoTec GmbH ("sphingotec", Hennigsdorf, Germany) today announced a publication in Critical Care1 with data on 2,000 ICU patients demonstrating that sphingotec‘s proprietary biomarker bio-ADM® (Bioactive Adrenomedullin) not only identifies high-risk patients for septic shock at admission but also identifies patients in the general ICU patient population who require immediate life-saving therapeutic intervention.

In an observational ancillary study to the FROG-ICU study, high blood levels of bio-ADM® at admission to the ICU were an early predictor of the requirement for organ support and treatment with ionotropes and vasopressors. Elevated bio-ADM® blood levels were also significantly associated with a prolonged length of ICU stay and fatal outcomes within 28 days post-admission, whereas low levels of bio-ADM® at admission were associated with positive outcomes.

This study is the largest published investigation on bio-ADM® in a patient cohort of which about 25% of patients suffered from sepsis and 75% of patients had conditions that were not sepsis-related. According to principal investigator Prof. Alexandre Mebazaa (Hôpital Lariboisière, Paris, France), the results demonstrate that bio-ADM® is not only a biomarker indicating impaired endothelial function in patients with septic shock as previously shown2, but also identifies further ICU patients who require rapid therapeutic intervention at admission due to distortion in endothelial function, which is independently associated with malperfusion of organs.

Previous data from more than 20,000 patients provide evidence, that high blood levels of bio-ADM® reflect impaired endothelial function independently from inflammation and other co-morbidities. High bio-ADM® blood levels indicate distortions in the barrier function of the endothelium before the patients progress to a critical stage. Failure of endothelial function has been demonstrated to precede the life-threatening blood pressure drop that causes shock and multiorgan failure e.g. in patients with sepsis at ICUs and in emergency departments (EDs) 2-3. Each year, 6 million people die from sepsis, one of the largest contributors to global disease burden causing $24 billion in direct annual costs to the U.S. healthcare system alone. As elevated bio-ADM® blood levels precede septic shock, bio-ADM® screening can identify risk patients who require early life-saving therapeutic intervention.

“The new study results add data to the broad body of existing evidence that our biomarker bio-ADM® can reliably support critical care physicians in identifying high-risk patients when they first present at the ICU,” said Dr. Andreas Bergmann, founder and CEO of sphingotec. “We are set to launch the fully automated CE-IVD-marked point-of-care bio-ADM® assay on our widely established Nexus IB10 immunoassay platform by mid-2020. We are convinced that this rapid test for bio-ADM® will support earlier treatment decisions and improve outcomes of patients at ICUs and emergency departments.”

About bio-ADM®
As a marker of endothelial function, bioactive Adrenomedullin (bio-ADM®) enables both prediction of circulatory shock before blood pressure decline, e.g. in septic patients, and diagnosis of residual congestion in acute heart failure patients. Data from more than 20,000 patients provide evidence, that high plasma levels of bio-ADM® reflect impaired endothelial function independently from inflammation and other co-morbidities. High bio-ADM® plasma levels indicate distortions in the barrier function of the endothelium before the patients progress to a critical stage. Failure of endothelial function has been demonstrated to precede the life-threatening blood pressure drop that causes shock and multiorgan failure e.g. in patients with sepsis at ICUs and in emergency departments (EDs). As elevated bio-ADM® plasma levels precede septic shock, bio-ADM® screening can identify risk patients who require early life-saving therapeutic intervention.

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.
