Biomarker-guided trial opens new avenues for personalised medicine in COVID-19
14 Apr 2022
A multi-centre study led by the University Hospital Hamburg-Eppendorf (UKE) is evaluating one of the first personalised approaches for moderate to severe COVID-19 patients. The innovative biomarkers bio-ADM and DPP3 are guiding the enrollment of patients suffering from endothelial barrier dysfunction. The biomarkers are measured with point of care tests for timely decision making.
Diagnostics company SphingoTec GmbH (SphingoTec) announced the implementation of two critical care biomarkers to guide the application of a potential new drug candidate for the treatment of COVID-19 patients. The personalised approach will distinguish between separate clinical pathways, requiring different treatment decisions.
This trial will implement the biomarker bioactive Adrenomedullin (bio-ADM) for early identification of endothelial dysfunction (1), which plays a central role in the pathophysiology of COVID-19 (2). The drug candidate Adrecizumab targets septic shock patients with high bio-ADM levels to restore the endothelial barrier function (3), and has already shown favourable outcomes in a case series of eight severe COVID-19 patients (4). At the same time, patients with high Dipeptidyl peptidase 3 (DPP3) levels will not be included in the trial. The biomarker DPP3 is indicating another underlying disease mechanism leading to cardiac depression and requiring different therapeutic options (5). Both critical care biomarkers are measured via SphingoTec’s rapid point of care platform Nexus IB10. For more information visit https://sphingotec.com/science/acute-care-pathways/covid-19 .
PD Dr med Mahir Karakas (Department of Intensive Care Medicine at UKE) said, “Not all COVID-19 patients have the same disease course and the pathology is very different. Therefore, we have to adapt the treatment to each individual patient. We will now use in a double-blind randomised multicentre trial the biomarker bio-ADM and DPP3 which proved to be useful for patient enrichment in a phase II trial for the treatment of septic shock.”
This is one of the first personalised, biomarker-guided trials in moderately to severely ill COVID-19 patients. The multicentre study led by UKE plans to enrol more than 200 patients for treatment with the new compound (6). Adrecizumab is provided by Adrenomed AG, and the critical care biomarkers are determined via SphingoTec’s rapid point of care platform Nexus IB10.
Dr Andreas Bergmann, founder of SphingoTec and co-founder of Adrenomed stated: “The innovative biomarkers generate better insights into the pathophysiology of critically ill patients. This is translated into clear decisions that allow better treatment guidance and ultimately reduce mortality. This study represents a leap from “one drug fits all” to a personalised approach in treating COVID-19.”
