  • Dipeptidyl Peptidase 3 release is a fatal clinical pathway in severe COVID-19 patients resulting in organ dysfunction and short-term mortality
  • New COVID-19 trial conducted by University Hospital Hamburg-Eppendorf is implementing a biomarker-guided therapy using DPP3 and bio-ADM for patient enrollment  
  • Targeted intervention for specific activated pathways in COVID-19 patients is crucial to ensure treatment success

Hennigsdorf/Berlin, Germany, April 11, 2022- 4TEEN4 pharmaceuticals GmbH announces today that its biomarker DPP3 will be used in a biomarker-guided trial in severe COVID-19 as communicated by the University Hospital Hamburg-Eppendorf (UKE) and SphingoTec GmbH. The study will be using two biomarkers, bioactive adrenomedullin (bio-ADM) and dipeptidyl peptidase 3 (DPP3), for patient stratification and inclusion criteria for the use of Adrecizumab (1). This revolutionary approach could serve as a precision medicine strategy in patients with severe COVID 19 infection.

Similar to Sepsis, patients with severe COVID-19 infection undergo several life-threatening clinical pathways. Loss of endothelial function is a major pathway contributing to worsening lung function.  Another concurrent pathway is the uncontrolled release of DPP3 due to cell injury resulting in loss of organ function and hemodynamic instability (1,2).

Both clinical pathways can be detected by specific biomarkers, bioactive Adrenomedullin (bio-ADM) for the loss of endothelial function and Dipeptidyl peptidase (DPP3) for the loss of heart function. A thorough understanding of the heterogeneity of COVID 19 will enable the administration of the right intervention and could potentially make a difference between life and death (1,2).

Adrecizumab, a new drug candidate to treat endothelial barrier dysfunction, is under development for the treatment of septic shock and it is currently investigated in hospitalized COVID-19 patients (3,4). The trial will follow a biomarker-guided therapy approach treating only patients with endothelial barrier dysfunction (bio-ADM positive). Patients with high DPP3 levels indicate the use of different therapeutic options and will not be enrolled (3,4).

DPP3 is a novel biomarker developed by 4TEEN4 pharmaceuticals and out-licensed to SphingoTec GmbH. It is available on a point of care platform for rapid testing. In several studies with critically ill patients such as septic shock, cardiogenic shock, burn shock, severe surgeries, and COVID-19, high DPP3 levels have been associated with reduced cardiac output, multiple organ failure, circulatory shock, and short-term mortality. DPP3 mediates the degradation of Angiotensin II, a hormone important for hemodynamic balance and cardiac function. This inactivation leads to hemodynamic instability, resulting in short-term organ dysfunction (4,5).

To treat patients with high DPP3 and circulatory failure, 4TEEN4 Pharmaceuticals develops an anti-DPP3 therapy that restores cardiac function, hemodynamic stability and improves survival. The drug candidate anti-DPP3 antibody, Procizumab, already demonstrated efficacy in preclinical models and will enter the first-in-human clinical trial by the end of 2022.
Dr. Andreas Bergmann, founder, and CEO of 4TEEN4 mentioned: "We are developing Procizumab as a targeted therapy to be available for critically-ill patients suffering from organ dysfunction due to high DPP3 levels and provide them with a treatment option for hard-to-treat diseases such as septic shock, cardiogenic shock, and COVID-19"

About DPP3
Dipeptidyl peptidase 3 is an active enzyme that, when released into the blood, inactivates angiotensin II, a hormone that is important for hemodynamic balance as well as cardiac function. This inactivation leads to hemodynamic instability and consequently to cardiac dysfunction. The DPP3 release is a newly identified disease mechanism explaining short-term organ failure in critically ill patients. Early identification of DPP3 release may allow better patient stratification and earlier therapy escalation to improve outcomes.

About Procizumab
Procizumab is a humanized monoclonal antibody in preclinical development specifically binding circulating Dipeptidyl Peptidase 3 (DPP3). It will be a first-in-class drug that targets and modulates DPP3 as an essential regulator of cardiovascular function. Procizumab has an innovative mode of action, relevant to acute diseases. Massive cell death and release of DPP3 into the bloodstream lead to degradation of its substrates, including angiotensin II and enkephalin, which are responsible for cardiac and renal function regulation. Procizumab inhibits the activity of DPP3, thereby reducing bioactive peptide degradation, stabilizing hemodynamics, cardiovascular function, and potentially increasing survival chances e.g., in cardiogenic and septic shock. Preclinical studies of Procizumab in models of cardiovascular failure showed instant efficacy.
