Detailed Description
Adrenomedullin (ADM) is a natural occurring 52 amino acid peptide which is mainly expressed in endothelial and smooth muscle cells. ADM plasma levels are increased in patients with sepsis and related with severity of disease. ADM is a key regulator of vasotonus and of endothelial integrity in sepsis.
ADRECIZUMAB is an antibody against the N-terminus of ADM which only partially inhibits the bioactivity of ADM. Several septic animal studies have shown that administration of ADRECIZUMAB leads to reduced catecholamine demand, improved renal function, improved fluid balance and improved survival.
The administration of ADRECIZUMAB to rodents and non-human primates (NHP) has been tolerated very well. Single dose and repeated administrations over 14 days to rats and NHP in the GLP toxicology and safety study have not shown any clinical side-effects or histopathological findings.
Based on these data the starting dose for human beings should be 0.5 mg/kg ADRECIZUMAB as single infusion over 1 hour and should be increased up to 8 mg/kg.
