SphingoTec’s innovative biomarkers to enable personalized medicine in septic organ failure
• Sepsis is a life-threatening medical emergency that quickly escalates into multiple organ failure.
• SphingoTec’s biomarkers for assessing organ function in real-time help guide clinical decision making by providing patient-specific information.
• Multiple presentations at the Weimar Sepsis Update in Weimar help push forward the science and practice of precision medicine with diagnosis and biomarker-guided therapy.
Hennigsdorf/Berlin, Germany, September 9, 2021 –
Diagnostics company SphingoTec GmbH (“SphingoTec”) announces a series of presentations demonstrating the utility of its innovative biomarkers in sepsis, positively impacting diagnostic and treatment decisions for critically ill patients. The new data will be presented at the 10th Weimar Sepsis Update, Germany.
In the oral presentation on the “Properties of Proenkephalin in septic acute kidney injury”, Dr. med. Christian Nusshag presented the results of a prospective observational study and the performance of kidney function biomarker Proenkephalin (penKid). Measured on top of standard of care, penKid can reliably indicate changes in renal function more dynamically than serum creatinine and can also provide additional diagnostic information on renal function, even when the patient is under renal replacement therapy.
In addition to the research presentation, during a lunch symposium, new data will highlight the utility of the biomarkers in clinical routine as well as in biomarker-guided clinical trials in sepsis. In the presentation “Implementing new Biomarkers in Daily Practice: Proenkephalin and bioactive Adrenomedullin in sepsis”, Dr. med. Lukas Martin from the Uniklinik RWTH Aachen, shares the insights from the first hospital to have implemented the innovative biomarkers in clinical routine. The regular measurements of the biomarkers penKid and bio-ADM have supported clinicians to improve diagnosis, help earlier risk stratification and optimize the treatment of critically ill patients. Bioactive adrenomedullin (bio-ADM) is a dynamic biomarker delivering real-time information on the endothelial function, one of the most common causes of septic shock. Moreover, increased bio-ADM levels were used as inclusion criteria in the AdrenOSS-2 Phase II trial to identify patients with endothelial dysfunction. In the presentation “Biomarker-guided Approach for the Treatment of Septic Shock – Precision Medicine in the AdrenOSS-2”, Prof. Dr. med. Tobias Schürholz from the Uniklinik RWTH Aachen will show a closer look at the steps taken to achieve precision medicine in septic organ failure.
Dr. Andreas Bergmann, CEO and founder of SphingoTec said “it is clear that sepsis is not only characterized by a high incidence worldwide, but it is also diagnostically underserved. Our biomarkers provide actionable information on pathophysiological mechanisms in sepsis. By early identifying and monitoring the hallmarks of sepsis, such as endothelial dysfunction and kidney dysfunction, our biomarkers can provide patient-specific information, paving the way for personalized medicine in sepsis, and beyond.”

• New ELISA sphingotest® penKid® enables widespread measurement of the kidney function biomarker Proenkephalin 119-159 (penKid) using standard laboratory equipment. • Only available test to match SphingoTec’s reference chemiluminescence assay, developed with patented high-sensitivity technology to provide consistent results across platforms. Hennigsdorf/Berlin, Germany, April 28 2026 - SphingoTec GmbH announces the launch of the ELISA sphingotest® penKid®, a new assay designed to make testing of its proprietary biomarker broadly accessible to research laboratories and pharmaceutical partners. Providing ease-of-use and precision, the test facilitates large-scale investigations of human kidney function in both acute and broader clinical research contexts. Responding to growing research interest The launch follows increasing demand from the scientific community to study penKid - a biomarker reflecting the current state of kidney function in critical care environments. While SphingoTec’s high-sensitivity sphingotest® penKid® assay serves as the reference method for clinical research and third-party IVD assays, the assay technology requiring dedicated equipment was not easily adoptable in research laboratories. The new ELISA sphingotest® penKid® now allows researchers worldwide to benefit from SphingoTec’s patented detection technology using standard photometers, extending penKid testing capability to a wider range of laboratories. Proven performance and data continuity The ELISA sphingotest® penKid® has been developed to achieve excellent correlation with SphingoTec’s reference chemiluminescence assay, ensuring consistent, high-quality results across different assay platforms. Both methods share the same underlying technology capable of detecting penKid concentrations in the picomolar range. Thanks to this technology transfer, researchers can rely on the same analytical precision and reliability that supported the clinical studies establishing penKid as a valuable kidney function biomarker. The assay’s robust design and German manufacturing ensure durable consistency and reproducibility. With this research-use ELISA, SphingoTec responds to the increasing availability of non-validated assays and encourages researchers to not compromise assay quality and performance to ensure trustworthy results - since data from non-validated tests may reflect assay limitations rather than the true performance of the penKid biomarker. Complementary approaches for clinical use and scientific exploration SphingoTec pursues its commercial strategy for the biomarker penKid through strategic out-licensing partnerships such as Boditech Med, which has developed an IVDR-certified assay for routine clinical use and rapid diagnostics. The newly launched ELISA sphingotest® penKid® represents a complementary initiative, specifically designed to support high-throughput clinical and translational research. Through this dual approach, SphingoTec reaffirms its commitment to fostering scientific collaboration and promoting the broader exploration of penKid across diverse research settings. “Developing the ELISA sphingotest® penKid® reflects our long-term commitment to improving critical care diagnostics,” said Deborah Bergmann, Managing Director and CEO of SphingoTec GmbH. “Beyond its currently validated clinical applications, we see strong potential for penKid to support research and improve diagnostics in other fields where kidney function is relevant.

• 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.
