Active participation with the industry

Chairman or member of the Steering Committee of more than 15 phase II and III studies on heart failure. The most recent are: FROG-ICU (2015, data presented as Late Bracking Trial at the European Society of Intensive Care Medicine, 2015), TRUE-AHF (2016, data presented as Late Bracking Trial, in Rome at the European Society of Cardiology in August 2016).

Member of the Board or Senior Consultant of the following Medical and biotech companies:
- Sphyngotec (sphyngotec.com): I lead the program of assessing the prognostic value of plasma adrenomedullin in intensive care units; data are provided by the international FROG-ICU study (2200 patients). In addition, Adrenoss (600 septic shock patients, 1.5 Millions Euros) was finished in July 2016.
- Adrenomed (adrenomed.com): Chair of the Adrecizumab Program in humans (5 Millions Euros) with the objective of assessing benefits of antibodies against adrenomedulline in improving organ dysfunction in sepsis; a paper was published to recommend how to design phase II in sepsis Mebazaa A et al. Designing phase 3 sepsis trials: application of learned experiences from critical care trials in acute heart failure. J Intensive Care. 2016 31;4:24

For years, clinicians thought that AHF and its associated organ injury were due to reduced cardiac output. Several studies including a meta-regression of AHF trials using pulmonary artery catheter showed that cardiac output was rather preserved. When invasive hemodynamic was measured within few hours of admission for AHF in patients with acute dyspnea and with known low left ventricular ejection fraction, filling pressures of right and left ventricles were strikingly elevated. This confirms that acute pulmonary edema is related to striking increase in left atrial pressure. Increased filling pressure of the right ventricle demonstrated that patients with low left ventricular ejection fraction have also a striking congestion upstream the right ventricle. Despite striking biventricular congestion, cardiac output was preserved. In summary, congestion is the predominant clinical profile in most patients admitted with acute heart failure (AHF) and also the main mechanism of organ injury and impairment in those patients.
In AHF, injury and dysfunction of target organs such as heart, lungs, kidneys and/or liver are associated with increased risk for death. In recent years, it appeared that restoring organ function after decongestive therapies has been associated with a lower risk for post-discharge mortality. Treatment strategies that specifically prevent, reduce or reverse organ dysfunction remain to be identified and evaluated.
Defining adequate endpoints of decongestion is a major clinical challenge in AHF. Change in body weight is often used as a guide, but this approach is frequently inadequate as body weight is not increased in all patients and does not reflect congestion caused by vascular-type fluid redistribution. Novel biomarkers to achieve decongestion are needed. We recently identified the endothelial marker CD146 that is released by vascular stretch. Circulating CD146 was correlated in several cohorts to the size of inferior vena cava. Furthermore, in dialysed patients, changes in volemia between dialysis were correlated to changes in circulating CD146.
The treatment of congestion, especially acute pulmonary oedema remains largely opinion-based as there is a general lack of robust evidence to guide therapy. Yet, managing patients with AHF remains a clinical challenge and current therapies have uncertain impacts on long-term morbidity and mortality. The use of therapies that prevent or reverse congestion-induced organ injury may represent a strategy to reduce subsequent organ impairment and morbidity that is more successful than the traditional approach of targeting dyspnoea relief.
