sphingotec and Shuwen Biotech partner to market sphingotec´s biomarkers portfolio in China
Hennigsdorf-Berlin 14. August 2017
German diagnostic company SphingoTec GmbH (Hennigsdorf) and Chinese Company Shuwen Biotech Co. Ltd (Deqing) have signed an agreement to market Sphingotec’s biomarkers portfolio in China.
Under the agreement, Shuwen will directly develop and market Sphingotec reliable immunoassays. For acute care, these are the Sphingotest® penKid and Sphingotest® bio-ADM tests, set to improve therapy monitoring and outcomes in intensive care units and emergency departments.
For the “Medicine of the Future” predictive test field, the sphingotest® pro-NT, sphingotest® pro-ENK, sphingotest® vr-hGH and sphingotest® ApoE4 are set to improve prediction and hence timely prevention of life-threatening diseases such as breast cancer, cardiovascular disease and Alzheimer, respectively.
In the acute care field, bio-ADM is a biomarker for vascular dysfunction, oftentimes causing worsening or escalation of conditions in various disease states. For example, bio-ADM predicts septic shock in critically ill patients and thus can guide treatment choices. In congestive heart failure, bio-ADM is the first biomarker that identifies patients having (residual) edema, caused by incomplete response or therapy resistance to decongestion therapy with loop diuretics. Septic shock is the most expensive conditions treated in the US hospital with a mortality rate of up to 80%, while unidentified residual congestion is the major cause for re-hospitalization and post-discharge mortality in congestive heart failure patients causing 30% of deaths and global annual cost of US$39bn.
penKid is a kidney function biomarker predictive for development of acute kidney Injury (AKI), a condition that complicates up to 30% of all hospital admission and that widely increase mortality and length of stay.
„We are delighted that Shuwen will distribute our biomarker portfolio in China“, said Dr. Andreas Bergmann, founder and CEO of SphingoTec GmbH. „Our patent-protected assays support physicians with information needed to improve patient management in acute settings and in prevention of life-threatening diseases“.
„The introduction of sphingotec tests is a major step forward for the Chinese healthcare system“, said Jay Z. Zhang, CEO of Shuwen Biotech. „Both acute care and disease prevention will vastly benefit from the sphingotec® biomarkers by supporting timely and clear clinical decision making to change patient outcome.
About penKid:
penkid is the very first plasma marker to monitor renal function, which is independent from comorbidities and inflammation and provides timely information about the changing kidney function in critically ill patients. sphingotest® penKid is non-inferior to the gold standard in vivo measurement of glomerular filtration rate (GFR) and penkid is elevated about 24-48 h earlier than the standard marker serum creatinine in patients developing acute kidney injury (AKI). These features enable physicians to predict, diagnose and closely monitor worsening and improving kidney function in critically ill patients. In congestive heart failure, penKid allows to adjust diuretics dosage to the situation in individual patients.
About bio-ADM:
As a marker of acute vascular endothelial dysfunction, bio-ADM enables both prediction of circulatory shock, e.g. in septic patients, and prediction of residual, diuretic resistant congestion in acute heart failure patients. bio-ADM plasma levels below the cut-off value of 70 pg/ml indicate successful diuretic therapy.
About pro-NT & pro-ENK:
pro-NT is a strong risk predictor for the development of breast cancer in the next five years. This predictive power can be further enhanced by the measurement of Sphingotest® pro-ENK, which results can be added on top of pro-NT to further quantify the risk of developing breast cancer. In contrast to genetic testing that solely focus on the encoded predisposition to develop breast cancer, pro-NT and pro-ENK values represent the phenotype and show to change following lifestyle adjustments.
About vr-HgH:
vr-hGH allows for the assessment of future onset of cardiovascular events in male, such as stroke and myocardial infarction, with a predictive power that largely overshadow the currently known measured parameters like troponin and natriuretic peptides.
About ApoE4: ApoE4 is a reliable and simple method to detect Apolipoprotein 4, a protein that is widely known to be connected to the future onset of Alzhaimer Disease. Sphingotest® ApoE4 is much simpler and cost-effective than the currently used genetic tests.

• 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.
