• Alliance marks first penKid licensing agreement for high throughput immunoassay.
• Partnership leverages SphingoTec's proficiency in acute kidney injury testing, and Beckman Coulter’s extensive, globally installed Access Family of immunoassay analyzers.
HENNIGSDORF/BERLIN, GERMANY — October 9, 2024:
Diagnostic company SphingoTec GmbH (“SphingoTec”) today announced a new partnership with Beckman Coulter Diagnostics Inc.
(“Beckman Coulter”). Through this collaboration, the companies will bring an assay for SphingoTec’s innovative kidney function biomarker, Proenkephalin 119-159 (penKid), to Beckman Coulter’s extensive test menu for use on the Access Family of Immunoassay Analyzers. This alliance marks the first central laboratory license for a penKid assay and aims to significantly enhance the diagnostic capabilities for acute kidney injury (AKI) globally, by leveraging Beckman Coulter’s global installed base of instruments.
PenKid is a real-time biomarker in plasma designed to address critical gaps in the standard diagnostic practices for AKI, particularly in critical care environments. Specifically, scientific evidence shows that, unlike current methods, a penKid assay offers early detection of kidney function decline, unaffected by inflammation, potentially enabling earlier intervention and improved patient outcomes (1,2,3). The incidence of AKI is increasing in both hospital and community settings; it is estimated that more than 13 million people are affected by AKI annually worldwide (4, 5).
Under the terms of the agreement, Beckman Coulter will develop and validate a fully automated diagnostic test for penKid, leveraging SphingoTec’s IVD certified assay. This assay has already been implemented as a routine test in the first university hospitals. This collaborative effort will facilitate high-throughput availability of penKid assays in central laboratories, supporting critical care physicians with the ability for timely and precise kidney health assessment.
“Acute kidney injury exerts a profound impact on patients globally, complicates acute and chronic illnesses frequently resulting in poor outcomes, and rivals many other critical diseases in its severity and consequences,” said Kevin O’Reilly, President, at Beckman Coulter Diagnostics. “The published evidence for penKid testing combined with SphingoTec’s scientific expertise provides an exciting opportunity to improve kidney health management. Working with SphingoTec, our goal is to expand access to and improve workflow from this important kidney health innovation underscoring our commitment to enhancing patient care worldwide.”
Deborah Bergmann, Managing Director and CEO of SphingoTec, emphasized, “The development of a penKid-based assay for use on Beckman Coulter’s globally installed immunoassay platforms represents a significant step toward realizing our vision of transforming diagnostic innovation into tangible patient benefits. This partnership accelerates our mission to deliver precise, actionable insights to clinicians worldwide, ultimately improving outcomes for patients suffering from acute kidney injury.”

• 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.

• 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.
