sphingotec and GeneNews Limited/Innovative Diagnostics Laboratory (IDL) Sign a Licensing and Cooperation Agreement for the U.S. Market
Cambridge, Mass. – October 14, 2014
– SphingoTec GmbH, headquartered in Hennigsdorf, Germany with U.S. operations in Cambridge, Massachusetts, today announced that it has out-licensed two of its biomarker assays—sphingotest® pro-NT and sphingotest® pro-ENK—to GeneNews Limited (TSX:GEN). The biomarker assays will aid physicians in risk assessment for breast cancer in females in the general population. sphingotec discovers and develops blood tests to detect cancer, cardiovascular conditions and kidney disease in high-risk patients.
GeneNews expects to add sphingotest pro-NT to the menu of advanced cancer assays offered by its U.S. joint venture, Innovative Diagnostic Laboratory LLP (IDL), by early 2015. GeneNews/IDL will be the first major U.S. laboratory to sell and market sphingotec’s innovative breast cancer risk tests, allowing potentially millions of women to better understand their individual near-term risk of breast cancer. The company is also evaluating the potential expansion of IDL’s testing menu in the area of breast cancer risk prediction through the addition of sphingotest pro-ENK and other biomarker candidates.
GeneNews is committed to helping IDL become a leader in molecular diagnostics and personalized medicine, serving as a strong commercialization outlet for advanced cancer tests. Taking a "multi-view" approach to the diagnosis and treatment of cancer, IDL is working to assemble—through a combination of internal pipeline development, third-party licenses and potential acquisitions—a robust menu of novel, patent-protected cancer assays to be offered throughout the U.S.“We are excited to sign this agreement with GeneNews, especially during Breast Cancer Awareness Month,” said Dr. Andreas Bergmann, founder and managing director of SphingoTec GmbH. “Our partnership will allow sphingotec’s markers to be available to potentially millions of women in the U.S. It is our common goal to lower the incidence of breast cancer by providing tests that are reliable, cost-effective and accessible for patients at risk regardless of health coverage status.”
“sphingotest pro-NT is the third advanced cancer assay added to our offering menu beyond our ColonSentry blood test,” said GeneNews Executive Chairman James R. Howard-Tripp. “We believe sphingotest pro-NT represents a major step forward in breast cancer detection and management, and we are looking forward to making it available to U.S. physicians nationwide through IDL as soon as possible.”
Breast cancer is the second leading cause of cancer death in U.S. women, exceeded only by lung cancer. The American Cancer Society estimates that, in 2014, approximately 232,670 new cases of invasive breast cancer will be diagnosed in women, and approximately 40,000 women will die from the disease. As with most cancers, early identification of high-risk women and intervention are the keys to improved clinical decision making.
Unlike other blood tests on the market that look for genetic indicators for breast cancer, sphingotest pro-NT is a simple blood test for the determination of proneurotensin (pro-NT). sphingotest pro-NT detects the release of the satiety hormone neurotensin and is applicable to all female individuals, regardless of genetic predispositions. A study published in the peer-reviewed Journal of the American Medical Association (JAMA) in October 2012 demonstrated that the determination of proneurotensin levels offered a substantial advantage in prediction of breast cancer (O. Melander et al. [2012]. Plasma Pro-Neurotensin Independently Predicts Cardiometabolic Diseases, Breast Cancer, and Death In Women. Journal of the American Medical Association, 308[14], 1469-1475).
In addition, experts in the fields of breast cancer treatment and biomarker research also support the work sphingotech is conducting.
“Breast cancer risk prediction is a major advancement for science because it’s one of the main ways we can detect and treat high-risk individuals appropriately,” said Dr. Max S. Wicha, MD, professor of internal medicine and director of the University of Michigan’s Comprehensive Care Center. “This could be the future of lowering the incidence of breast cancer.”
“It is exciting to see that inexpensive, blood-based protein biomarkers are now available for detecting women who are at high risk for breast cancer, even when the family history is completely negative,” said Dr. Alan S. Maisel, professor of medicine at the University of California San Diego and director of the Coronary Care Unit and Heart Failure Program at the Veterans Affairs San Diego Healthcare System.
A new peer-reviewed study in Physiological Reports is the first to evaluate Proenkephalin A 119-159 (penKid) for kidney functional reserve (KFR) assessment, a stress test designed to reveal loss of kidney capacity that may not be apparent from routine blood tests. Within that method, penKid stood out: its dynamic had a far wider range after a protein stimulus than cystatin C (44.2% vs. 10.5% median fractional change) while reaching its maximal response within approx. two hours after protein stimulation. The results extend the published evidence for penKid beyond acute kidney injury into a potential complementary application: assessing kidney functional reserve. Hennigsdorf, Germany – October 6, 2026 – penKid has been evaluated for the first time as a marker of kidney functional reserve (KFR): a new study in Physiological Reports (1) found that its response spanned a much wider range than cystatin C and creatinine clearance after a protein stimulus. The study in 62 participants marks the first published evaluation of penKid for this use. Clinical context and unmet need Kidney function may appear normal on a standard blood test until a large portion of capacity has already gone. Kidney functional reserve testing addresses this gap by measuring how much a kidney's filtration rate can still rise in response to a stimulus, most commonly a protein meal. Once that reserve narrows, the kidney has less room to compensate for future stress such as major surgeries. The study authors note that reserve testing is rarely used in clinical practice, largely because the reference method used, creatinine clearance, is cumbersome, requiring blood and urine collection, can be difficult to perform outside specialized settings, and is affected by processes in the kidney unrelated to filtration itself. Study design and key findings Researchers at the University of New South Wales and Prince of Wales Hospital in Sydney conducted the study in 62 participants: 40 patients having heart surgery, and 22 healthy people, including volunteers, kidney donors, and patients who had a kidney auto-transplant. Participants drank a protein shake, followed by hourly collection of blood samples over a five hour-period. Urine samples were also collected for creatinine clearance testing. After a high protein intake, kidney filtration increases for a few hours: this "extra work" is what the methods were designed to measure. PenKid showed the largest dynamic response, with a median fractional increase of 44% from baseline compared with 30% for creatinine clearance and only about 10% for cystatin C. Unlike creatinine clearance, penKid differentiated healthy participants from cardiac surgery patients, who had a lower KFR. The study also found penKid measurements to be more homogeneous than creatinine clearance measurements, indicating greater consistency across assessments. PenKid was also fast, reaching its peak functional response in about two hours, similar in timing to a two-hour diabetes test (oral glucose tolerance test). Implications for clinical practice Beyond its wider dynamic range, the authors highlight practical advantages specific to penKid-based functional reserve testing: no urine collection is needed, minimal fasting is required, and penKid enables near real-time assessment of kidney functional reserve from blood samples alone. These features suggest penKid may offer a fast and simple alternative to assess how much reserve an individual patient has. "PenKid gave us a fast, consistent read on how much filtration capacity a kidney still has in reserve," said Prof. Zoltan H. Endre, corresponding author of the study, Department of Nephrology, Prince of Wales Hospital, and School of Clinical Medicine, University of New South Wales, Sydney. "A signal that's clear, captured that quickly, turns a kidney stress test from a research tool into something a clinic could actually use." About penKid, scientific insights PenKid is a biomarker for real-time assessment of kidney function. Unlike creatinine, penKid levels are not influenced by inflammation or factors such as age or sex, and prior studies show penKid can detect acute kidney injury (AKI) up to 48 hours before conventional criteria are met (2,3). The new Physiological Reports study provides data for another, complementary application: measuring kidney functional reserve to identify subclinical kidney disease.

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.
