Ilomedin in Septic Shock With Persistent Microperfusion Defects (I-MICRO)

• Status: Recruiting
• Trial end date: 2022-08-18
• Target enrollment: 0
• Participant gender: All

Summary

Septic shock remains a major cause of death in critically ill patients. Alterations in microcirculation have long been proposed as a key pathophysiological factor of organ dysfunction and death in septic shock patients. Persistence of mottling, prolonged skin recoloration time and cyanosis of the extremities are the easily and frequently observed manifestations of these microcirculatory disorders. Ilomedin is a prostaglandin analog with a potent vasodilatory effect together with anti-thrombotic properties (inhibition of platelet aggregation) preferentially at the microcirculatory level. An increase in cardiac output with increased arterial oxygen delivery has been observed in clinical and preclinical studies with no episodes of hypotension. Improvement in mesenteric perfusion has moreover been observed in experimental sepsis using Ilomedin. Our group has furthermore reported that administration of Ilomedin in patients with refractory septic shock (peripheral hypoperfusion) resulted in a rapid and sustained improvement in peripheral perfusion. Altogether, Ilomedin may prevent or improve recovery of organ dysfunction in septic shock patients through recruitment of the microcirculation and, thereby, ultimately improve outcome.
