Diagnostics company SphingoTec GmbH (“sphingotec”) and 4TEEN4 Pharmaceuticals GmbH (“4TEEN4”) announced today the publication of new data showing that high blood levels of Dipeptidyl Peptidase 3 (DPP3) are indicative of upcoming multiple organ failure and mortality risk in burn patients. DPP3 is a proprietary biomarker of 4TEEN4 for hemodynamic instability and cardiac depression. Sphingotec has in-licensed global rights to develop and commercialize in vitro diagnostic (IVD) tests for the DPP3 biomarker from 4TEEN4 and made it available on its proprietary Nexus IB10 point-of-care platform.
The results from the recent study provide evidence that DPP3 blood concentrations in severely ill burn patients are indicating fatal outcomes. The data also shows that high DPP3 concentration in the blood is linked to circulatory failure, cardiac depression, and acute kidney injury. Decreasing DPP3 levels in the blood, on the other hand, indicate a substantially reduced risk of mortality.
According to a newly identified disease mechanism, the release of the cardiac depressant factor DPP3 into the bloodstream is a major cause of short-term organ failure: DPP3 is an enzyme that is present in many cell types and normally plays an important role in the recycling of cellular proteins. When massive uncontrolled cell death occurs, like in the case of burn patients, DPP3 is released into the bloodstream where it degrades angiotensin II, a peptide hormone controlling the heart function. Unphysiologically low levels of angiotensin II rapidly lead to cardiac depression and ultimately organ failure. Previously published data2,3 provided evidence that poor outcome of patients with severe heart failure or cardiogenic shock are caused by DPP3. Furthermore, the causal role of DPP3 in cardiac depression could be reproduced in several model systems.
“The new data adds to the growing body of evidence that places the cardiac depressant factor DPP3 in strong connection with short-term organ failure and high mortality in critical care settings. We have already started a collaboration with the critical care community to provide our fully automated DPP3 point-of-care test to support the management of acute care patients,” said Dr. Andreas Bergmann, CEO and founder of sphingotec.
