Adrecizumab in Cardiogenic Shock
Sponsor:

Dr. Made. Expert Karakas

Information provided by (Responsible Party):

Brief Summary:

Cardiogenic shock is a serious medical condition with high mortality and morbidity. This trial assesses safety, tolerability and efficacy of Adrecizumab on top of standard of care in patients with cardiogenic shock.

Condition or disease

Endothelial Dysfunction

Intervention/treatment

Adrecizumab

Phase

PHASE2

PHASE3

Detailed Description:

Despite optimal treatment the mortality in patients with cardiogenic shock still exceeds 50% and surviving patients mostly suffer from severe heart failure due to an impaired cardiac function.It is hypothesized, that Adrenomedullin is a key player in the (dys)-regulation of vascular integrity. 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.When the anti-Adrenomedullin antibody Adrecizumab is administered in the blood circulation at high concentrations by far exceeding those of plasma Adrenomedullin, the compartmental distribution of Adrenomedullin is altered. Adrecizumab, an IgG with a molecular weight of more than 150 kDa, is too large to freely diffuse from the blood circulation to the interstitium. With its fast association kinetics Adrecizumab quickly binds to Adrenomedullin in the blood circulation and "pulls" Adrenomedullin, which has been initially located in the interstitium, from this compartment to the blood circulation. The more Adrecizumab is applied, the stronger is the "pulling" effect and the higher the resulting concentrations of Adrecizumab-bound Adrenomedullin in the blood circulation. The increase of Adrecizumab-bound Adrenomedullin in the blood circulation occurs within 5-15 minutes after administration of Adrecizumab, since it induces a translocation of preformed Adrenomedullin. As a consequence of this redistribution, the Adrenomedullin concentration in the interstitium decreases, and less Adrenomedullin is able to act on smooth muscle cells to exert its vasodilatative activity. In the progression to cardiogenic shock, when it comes to excessive vasodilation and hypotension, administration of Adrecizumab thus can reduce vasodilation by substracting excessive levels of interstitially located Adrenomedullin.
