Brief Summary:

The clinical trial is designed as a prospective, multi-center, double-blind, randomised, placebo-controlled, interventional trial to assess safety, tolerability and efficacy of Adrecizumab (on top of SOC) in patients with COVID-19, and to evaluate if improvement of vascular integrity with Adrecizumab on top of SOC is superior to placebo/ control substance (NaCl 0.9%) on top of SOC in reduction of morbidity and mortality endpoints in patients with COVID-19.

The main reason for admission to ICU and need for mechanical ventilation of these patients is acute lung injury within a broad pneumonic spectrum, increased ventricular filling pressures and resulting congestion. It is hypothesized, that Adrenomedullin (ADM) is a key player in the (dys)-regulation of vascular integrity (Figure 2). Adrecizumab is the first-in-class humanized monoclonal anti-Adrenomedullin antibody, and acts as a long-lasting plasma Adrenomedullin enhancer stabilizing barrier function at a reasonable safety profile. The mode of action for the anti-Adrenomedullin antibody Adrecizumab has been developed on the basis of published data, own experimental data and theoretical considerations.
